1.1.1.20! root 1: 9B1230 lockscr/unlockscr fixes in drawing.c. ! 2: Add sdlgfx from Bernd [4] Lachner. ! 3: Filesystem asm code improvements from Toni (make it pic, call ! 4: setup_exter earlier in the boot sequence, etc.) ! 5: Also add Toni's patch to make rtarea position configurable (keep it ! 6: at 0xF00000 for now, though). ! 7: Avoid installing filesystem stuff if user didn't request to mount ! 8: directories. ! 9: BEAMCON0 is only available with ECS Agnus. ! 10: Revert some bogus parts of the write_log patch. ! 11: 9B1219 Add some missing clipping to the Picasso code. ! 12: Limit number of illegal-mem warnings. ! 13: 9B1217 Fix the GUI crash when changing floppies. ! 14: Changes to support programs that change between HAM/no HAM in the ! 15: middle of a line. ! 16: Some bug fixes, and a big fprintf->write_log patch from Alex Kazik. 1.1.1.19 root 17: 9B1125 Panning support for Picasso96 (in part from WinUAE). 18: More state save fixes from Toni, and a small disk.c update as well 19: which corrects track/gap lengths. 20: More evolution of the AHI code. 21: 9B1124 Merged a few more small pieces from WinUAE (larger pieces in case of 22: the Picasso code). 23: CLXCON2 was never called or statesaved. Fixed by Toni. 24: Sound sample frequency now always based on PAL timings. 25: 9B1123 Goodness! Massive memory corruption bug in picasso96.c - passing 26: last color changed to DX_SetPalette instead of count. 27: Fixes for the AHI code. 28: Changed prefetch emulation to be more similar to the one MAME uses. 29: Trace mode fixes (Bernd Roesch & myself). 30: 9B1122 Redo the ExNext code in the filesystem to make sure we always match 31: opendir with closedir and to fix some renaming problems. 32: Fix hd changing code in gtkui. 1.1.1.18 root 33: 9B1121 Mini-merge of noncontroversial WinUAE filesys.c code. 34: Add harddisk page to gtkui. Also change gui behaviour to wait for 35: the user to unpause before starting the emulator. 36: Add Toni's drive-led display. 37: Fixed a rather amazing source of crashes (we could fail to notice 38: the end of the frame in some cases). 39: Default to scanline mode. 40: Some tweaks to the SDL driver and the Win32 gui, mostly buffer-size 41: related. 42: Moved C source files back from tools directory (but still build them 43: there) to preserve my CVS history. 44: 9B1119 Move all the build tools (gencpu, cpuopti etc.) into their own 45: directory which is configured separately. This was necessary to 46: avoid picking up SDL CFLAGS (which can #define main to _SDL_main, and 47: that breaks if you don't link with SDL), and to make cross-compiling 48: at least a little more likely. 49: Remove sanity check for SDL header file - rely on sdl-config getting 50: things right (not that we have much choice). 51: Move thread support code past sound code in configure, and make sure 52: that SDL sound enables threads. 53: Move sername into options structure. 54: Check for existance of isinf/isnan before using them. 55: Rather large WinUAE merge - this tree compiles again under Windows. 56: Most of the additional features are missing though. 57: 9B1118 Restore code to mirror banks for 24 bit address space which got lost 58: when all the JIT memory changes were put in. 59: Speed up the CPU time calibration code. 60: Fix the broken file selector handling in the gtk ui. Add kickstart 61: selector. 62: Don't call XCloseDisplay, it apparently leads to crashes. 63: Try to solve the "missing write_log" problem in a sane way. 64: SDL joystick support. 65: When configure detects win32, use fsdb_win32 rather than fsdb_unix. 66: 9B1117 Proper masking for DDFSTOP; proper handling of AUDLEN == 0, changed 67: delayoffset code, gencpu BFINS fix, and lots of disk updates (all 68: Toni). 69: Some additional regs for move2c/movec2 (also by Toni IIRC) 70: 9B1115 COLOR_READ typo fix (Toni). 71: 9B1024 Filesystem reset leak fixes (Brian) 72: Allocate enough memory for custom state saving. 73: bploff renamed to bpl_off. 74: AGA copper cycle diagram (Toni) 75: Disable disk_data_used optimization. 76: 9B0926 Delayed palette setting for Picasso modes. Also fixed problem with 77: palette setting in CLUT emulation - we need to redraw the entire 78: screen if that happens. 79: 9B0921 Miscellaneous small bugfixes. Delete some obsolete code. 80: 9B0907 Beginnings of SDL support. Exterminated some penguins. 81: 9B0825 Some xwin.c fixes from Maik Qualmann. 1.1.1.17 root 82: 9B0730 Some sprite state machine tweaks. Fix sprite vs. DIW comparison. 83: HAM linebuffer was too small by half - oops. 84: Make absolutely, positively sure that when hsync_handler calls 85: sync_copper_with_cpu, we don't take any invalid shortcuts. 1.1.1.18 root 86: Memory management changes for JIT (Bernie [2], mostly). 1.1.1.17 root 87: 9B0729 Silly mistake - need to call flush_plane_data unless plfleft is 88: -1, even if no planes were enabled. 89: 9B0728 Small hack to reduce the time we lose with unnecessary 90: disk_doupdate_read calls. 91: Avoid calling flush_plane_data if we have no bitplanes enabled. 92: Tweak the SPCFLAG_INT handling to make "Delirium" demo work. 93: Limit rate of DDF warning messages. 94: Adjust display parameters so that things are shifted to the left 95: even more. 96: Fix (hopefully) CIA & blitter saving code. 97: 9B0727 Copper code reorganized; speedup code rewritten. Can now be 98: enabled with a GUI setting. 99: Fixed the delayoffset stuff. 100: 9B0725 AGA sprites, and some patches to sprite/playfield collision code, 101: mostly by Toni. 102: Fixed a small sprite restore problem; added missing code to map 103: fastmem banks when restoring them. 104: Some more state saving updates from Toni. 105: 9B0724 Fix a nasty bug in the copper SKIP instruction introduced by recent 106: changes. 107: Update the FAST_COPPER code. Not quite enabled yet. 108: More work on the memory configuration stuff. 109: Fix CPU type writeout in cfgfile.c (taken from WinUAE source). 110: Move the WOC demo BPLCON0 fix to compute_toscr_delay (Toni). 111: Added Toni's new disk patches, which include HD disk support by 112: Adil Temel. 113: Rewrote the memory and audio save/restore code. 114: Mask DDFSTOP with 0xFE, not 0xFC. 115: 9B0723 Yet another new and correct copper state machine (this time for sure) 116: Fix some AGA problems in DDF speedup code. 117: In gencpu.c, branch insns return a hardcoded cycle count; this had 118: not been updated for the CYCLE_UNIT stuff. Fixed. 119: xwin.c: If mouse is grabbed, we don't need mousehack. 120: Don't clear audio state if produce_sound == 0; this causes problems 121: if we want to turn the sound back on. 122: If an audio channel had a period of PERIOD_MAX, allow AUDxPER to 123: set its evtime back to a reasonable value. 124: Massive cleanup of memory initialization code; it will now use changed 125: prefs on reset. Added some memory options to gtkui.c. 126: Added Toni's state saving code, then added gtkui options and code to 127: initiate saving/restoring. 128: 9B0722 filesys.c: Fix writeout of hardfile params (Bernie [2]) 129: Add an A1000 Kickstart disk loader (Gerald Schnabel). Got rid of 130: the automount_uaedev code; we can detect the Kickstart version and 131: do the right thing. 132: Deleted a few unused variables (Toni) 133: Avoid aborting in decode_ham if Amiga code turns on the HAM bit but 134: has too few bitplanes (found by Toni). 135: Make the dummy mem bank return other values than 0; helps some 136: stupid memory detection code. 137: Implemented a little exec task lister for the debugger. 138: Added new debugger commands from Mark Cox. Improved his copper list 139: debugger by adding recorded timing information to it. 140: MOVE16 fixes from Gwenole Beauchesne. 141: xBCD fixes by Maik Qualmann, with some additional flag fixes by myself 142: (ABCD & SBCD behave exactly like on a 68000 now; dunno about NBCD). 143: 9B0520 AGA bscan2 fixes and disk.c kickstart speedup fixes from Toni. 144: Remove bogus changes I made to one of Toni's earlier disk.c updates. 145: Call RethinkICRA/B from INTREQ (suggested by Toni). 146: Properly save mixed_stereo setting. 147: NEGX uses X and Z (Bernd Roesch). 148: Danish keyboard support (Jesper Bojesen). 1.1.1.16 root 149: 9B0311 Repair "emulated but no output" sound setting. 150: 9B0310 Fix massive bug introduced in do_cycles_slow with the rescaling 151: changes. 152: CLXCON logic updated for AGA (Toni). Change meaning of collision_level 153: and add support for it in cfgfile.c. 154: 9B0309 Fix problem where a fsdb file could prevent deletion of otherwise 155: empty directory discovered by Torsten Enderling. 156: Rescale return values of CPU emulator functions. 157: 9B0225 Undo parts of the audio changes that made the "accurate" setting the 158: default. 159: 9B0221 Make fsdb_unix compile again. 160: 9B0219 Fix ddf for cases where start isn't aligned to fetchunit. 161: Fix some problems with the sound code going into infinite loops or 162: crashing. 163: Try to re-add Toni's ddf delay fixes properly. 164: Added a fix from Krister Walfridsson for X11 SHM code. 165: Rename OBJECT_NOT_FOUND to OBJECT_NOT_AROUND (not sure why, but the 166: win32 port does this; Fellow picked it up as well...) 167: Give in and allocate ainos with xcalloc. 168: Import fsdb_win32 code from Fellow. 169: Some tidyup and fixes in fsdb code. 170: Lose the lastdiv10 variable, and update CIA timers when reading them 171: (mostly by Bernie [2] Meyer) 172: Move reset_uaedevices and get_new_device to filesys.c. Add extra 173: parameter to get_new_device. 174: 9B0213 Fix mouse pointer jumping bug in X11 code (Ralf Hoffmann) 175: Scaled event handling by a factor of 512.

Instead, allow SPRxPT 645: functions to set the state to SPR_restart in the vertical blanking 646: area. 647: 971030 Fix 8MB Chip RAM. 648: filesys_dev_storeinfo: New function and calltrap. Use it to store 649: per-unit data (which now includes geometry information) in the 650: parampacket. Modify filesys.asm to use it instead of trying to find 651: the values by itself. 652: 971028 "AMIROMTYPE1" has 11 characters, not 0. 653: 971027 Implement encrypted ROM features.

Fix configure so that it can be enabled 775: Get rid of spixstate by implementing a new sprite drawing method. 776: 970607 do_copper_cheat(): New function, Implement inaccurate, line-based 777: copper as an option (-C). calc_copcomp_true(): Fix possible hr 4 plane 778: bug (split the wait into several pieces in this mode). 779: Allow 0 bytes for fast and bogomem (to override .uaerc) 780: 970606 Fix some bugs in transdisk, and make it compile with SAS C (Joanne Dow) 781: Stupid compilation fixes: Get rid of "==" in shell scripts, check that 782: B300 and friends are defined in serial.c before using them. 783: Implement blitter prefetch. Fix silly typo in main.c that prevented 784: immediate blits. 785: init_ham_decoding(): new function, handles case where the first few 786: pixels of a HAM display are outside the window. 787: 970605 disk.c: Get rid of need_read. Save cylinder/track number for the data 788: in the MFM buffer for each drive. Force rereads on disk insert and 789: write operations. In drive_fill_bigbuf(), do nothing if saved data 790: matches current. Fix disk change logic: give the program time to read 791: the change bit a couple of times before inserting a new disk. 792: custom.c: Fix really subtle bug: when deciding a line as border, 793: plfstrt/plflinelen were not set up properly, which could confuse 794: post_decide_line(), and eventually there would be lines decided as 795: playfield with plfstrt == 0, plflinelen == -32 ==> Bang. A related 796: bug was that setting DDFSTRT to 0 would result in both plfstrt and 797: plfstop having value 0. 798: gfxutil.c: Fix bug that could cause color values to go out of bounds. 799: xwin.c, svga.c: When dithering, color values were not doubled properly. 800: 970604 filesys.c: when deleting an a_ino, remove it from hash table (Mathias 801: Ortmann). In do_find(), if creating a file failed and we didn't have 802: an a_ino before, call delete_aino on the one we created. 803: More configure changes: Add $X_PRE_LIBS and $X_EXTRA_LIBS in some 804: places. See if MIT-SHM support for X will compile and link. Always 805: compile it in if it will. Turn DONT_WANT_SHM and LOW_BANDWIDTH into 806: run-time options (-T, -L). Use single line buffer when dithering and 807: in low-bandwidth mode (but in all cases there's a full buffer for the 808: X image). 809: memory.c: Don't map in custom regs at 0x200000 if chipmem_size > 2MB. 810: Split up init_sound(): new function setup_sound(). Make "-B" accept 811: minimum and maximum values as in Gustavo's latest patch. Add code to 812: tui.c to support changing buffer size, number of bits and frequency. 813: 970603 If using compiler, define NO_EXCEPTION_3 and NO_PREFETCH_BUFFER. 814: (bugreport by Raphael Poss). 815: GGI support from Christian Schmitt/Stefan Reinauer. More serial patches 816: from Stefan. 3 button joystick patch from Mathias. 817: Add linemem field to gfxvidinfo, for systems that don't want to keep 818: a buffer of the full screen. Adjust custom.c to use it instead of 819: bufmem if it's not NULL (mostly by Mathias). svga.c, xwin.c: Use single 820: line buffer in some cases. xwin.c: If USE_DGA_EXTENSION, undef 821: LOW_BANDWIDTH. Move test of DONT_WANT_SHM after inclusion of config.h 822: Make configure.in a bit more structured. 823: Move colormodes array to main.c. 824: 970602 gfxlib.c: Start implementing layers workalike. 825: md-i386-gcc/support.c: Don't mix sleep and alarm. (Petter Schau) 826: 970601 Remove may_run_compiled. Print error and abort if m68k_go is called 827: twice. 828: Fix yesterdays bugfix in svga.c. 829: Change FRAME_RATE_HACK so it tries to average the times a bit. 830: Re-implement a call_m68k function in autoconf.c. The new version 831: works by doing some heavy setjmp/longjmp magic and switching stacks. 832: With this, it's even possible to call things that Wait(), so use 833: the new functionality in gfxlib.c to call LockLayer() in WritePixel(). 834: 970531 Turn some inline functions in memory.h into macros. Get rid of 835: get_along and get_aword. Implement CIA A OVL bit. 836: main.c: Add missing close_sound() call. 837: Remove INTEL_FLAG_OPT, use X86_ASSEMBLY for everything. 838: tui.c/svgancui.c: Implement scrollable menus. Add code to select 839: video mode from a given list. Add "graphics_setup" call to graphics 840: specific files. Use it in svga.c to build a video mode menu. 841: Fix bug in svga.c that would crash non-linear modes. 842: disk.c needs to include gensound.h and sounddep/sound.h. 843: Fix bug in fuzzy_memset. In pfield_init_linetoscr, always adjust ddf 844: values if lores hack is being used. 845: 970530 Apply some patches by Samuel Devulder. 846: 970529 filesys.c: In "Houston, we have a problem" case, do not only delete 847: the oldest ExKey, but also use it instead of random memory for the 848: new one. Attempt to reduce the number of lost exkeys by allocating 849: them in action_examine_next instead of action_examine_object. 850: Initialize the "uniq" field of unit->rootnode. 851: Attempt to speed up sprite drawing loop. 852: Implement sprite<->sprite collisions. 853: Get rid of -Wtraditional. 854: 970524 New config option NO_PREFETCH_BUFFER. Emulate 16 byte prefetch if 855: unset. 856: For exception 3, the stack frame seems to be: 857: (saved SR).w, (faulting address).l, (faulting instruction).w, 0.w, 858: (pc at fault time).l. Make everything that could generate this fault 859: handle it properly. That got Cybernoid II working! 860: 970523 Makefile.in: Make sure $(DEBUGFLAGS) is used for CPU emulation files. 861: memory.c: Don't map chipmem at 0x200000, use custom chip bank for now. 862: 970507 configure.in: Mutate ac_cv_c_inline=no to ac_cv_c_inline= 863: Check for tcgetattr, <sys/termios.h>, cfmakeraw, <sys/ioctl.h> 864: Check for sem_init in -lposix4 (Marc Zimmermann) 865: serial.c, cia.c, cia.h, serial.c: changes (Stefan Reinauer) 866: Make disk gap 360 (Michael Krause) 867: 970404 In configure, check for features.h before including it in test program. 868: 970401 New option -4. Bugreport by Mirko Viviani. 869: 970324 Petter Schau says the exception frame for Bus Error and Address Error 870: is 14 bytes, not 6, on the 68000. Change Exception() accordingly. 871: It's *** OUCH *** day! Make hardfile beginio return the correct value. 872: Also load execbase before calling ReplyMsg(). 873: It's *** OUCH *** day again! The filesystem asm code was an odd number 874: of bytes, leaving the hardfile code unaligned. 875: 970318 custom.c: Rename spron to sprst, and use new variable spron to indicate 876: for which sprites the sprite pointer registers have been written. Don't 877: do sprite DMA if spron==0. (The problem was that some programs write 878: SPRxCTL and then SPRxPT, which used to set the sprite state to 879: SPR_restart, but it must be SPR_waiting_start.) 880: Turn a few m68k_reset()s into uae_reset()s. 881: New variable nr_joysticks. Delete joystickpresent. New arg "nr" for 882: getjoystate() and read_joystick(). 883: New extra keycode AK_RCTRL. Handle multiple joysticks & different key 884: replacements in keybuf.c/custom.c. Make tui.c handle all the settings. 885: 970310 od-linux/joystick.c now compiles again without the joystick header. 886: Fix some problems in configure; also check whether [n]curses.h defines 887: attr_t. Keep count of warnings and errors during configuration and 888: print a hopefully helpful message at the end. 889: disk.c sanitized by Mathias Ortmann. 890: Change the replacement getopt around a bit. 891: execlib.c, timerdev.c: Files removed. This will never be compatible 892: enough. Also remove related code (several SPCFLAGs, etc.) 893: Make main.c a bit nicer by introducing additional defines for the t-* 894: files. Also canonicalize the .uaerc file on all systems, eliminating 895: lines starting with '#' in the process. 896: Remove code in autoconf.c to set up 8MB chip; move it to filesys.asm. 897: Try doing the copper end-of-line hack in copper_memory_cycles(). 898: Disable the copper speedup hack. 899: 970309 Add a small, dumb hash table to struct _unit to speed up repeated 900: aino lookups. Delete aino in action_delete_object(). Move children in 901: action_rename_object(). In action_examine_next(), call new function 902: lookup_child_aino_for_exnext() which behaves more or less like 903: lookup_child_aino(), except it uses new function get_aname() to 904: translate filenames. 905: More portability fixes. New links set up in configure: sounddep, 906: target.h. All machine-dependent and joystick code removed 907: from os.c, renamed to audio.c. os.h renamed to audio.h, joystick stuff 908: moved to joystick.h. New directory targets/. 909: missing.c: New file. 910: 970308 Rewrite filesystem. Now it keeps one unique "a_inode" structure for 911: every object in the filesystem. This contains Amiga name, native 912: name, Amiga permissions, lock counts and several links for building 913: a tree structure. Keys are now made only for files which need a fd 914: and a file position. 915: Treat invalid locking modes als shared. 916: Comment out the code using readdir_r because that function appears 917: to be broken in glibc-2.0.1. 918: Clear RES2 in all packets before handling them. 919: Give mousehack the same task priority as the input.device. 920: Fix (?) some silly bugs in disk.c. 921: 970307 Include some Acorn port code from Peter Teichmann. 922: Yet Another Serial Diff from Stefan. 923: 970306 filesys.c: Don't just crash if lookup_key() has no success. 924: action_find_write() is supposed to create the file if it does not 925: exist. 926: 970305 More DOS patches. Make the Makefile parallel-make safe. 927: svgancui.c: Do cyclic search if character is typed in file selector. 928: my_alphasort(): New function (work around glibc bug) 929: custom.c: Fix error in yesterdays change. 930: filesys.h: New file. 931: 970304 New serial patch from Stefan and Christian. 932: Remove the assembler code to generate inputevents. Instead, add a new 933: Amiga C program ("mousehack") which does the trick. New function 934: mousehack_helper() in custom.c, activated by calltrap 0xF0FF70. 935: Mouse default is now always normal_mouse, not follow_mouse. 936: Do disk change checks only every 1/2 second. disk.c: Reverse 937: nodskchange to dskchange, and make sure there has been a step with the 938: drive empty before calling drive_insert() from DISK_check_change() (but 939: this _still_ doesn't work. Arrrghh). 940: 970303 filesys.c: Initialize _all_ of struct _unit in startup_handler(). 941: Remove message_lock and friends and use new variables cmds_sent, 942: cmds_acked and cmds_completed to determine when to send dummy messages. 943: Changed examinekey handling so that "dir all" on a large tree doesn't 944: crash anymore (it used to reuse the top-level exkeys which were still 945: in use after a wraparound). Don't allocate examinekeys if we're 946: examining files. 947: Check for readdir_r in configure. Use a wrapper my_readdir() around 948: either readdir or readdir_r. 949: Call filesys_reset() also from filesys_diagentry(). 950: Get rid of most of uaelib.c. Now there isn't a library, just a calltrap 951: at 0xF0FF60. Changed uae_pragmas.h accordingly and recompiled uaectrl. 952: Added a bunch of "volatile"s in various places in filesys.c and 953: penguin.h. 954: Make the filesystem reset-safe in the threaded case (paranoia changes). 955: Check disk changes only every 1/10 second in vsync_handler(). 956: Add assembler code to generate InputEvents once every vblank to 957: filesys.asm. (Doesn't work yet.) 958: 970302 filesys.c: Get rid of DosPacket type, pass pointers into Amiga memory 959: instead. Use GET_PCK_* and PUT_PCK_* macros to access fields. 960: Start making filesystem code thread safe & multithreaded. Move static 961: variables from some functions into struct _unit, likewise the key 962: and exkey variables. Add code to filesys.asm to queue commands which 963: did not complete and to reply to them later. Do multithreading if 964: compiled with SUPPORT_THREADS. See source for details. 965: Change hardfile and uaelib code not to call 68k routines. Make emulator 966: traps more efficient (no need to save regs, don't need SPCFLAG_EMULTRAP 967: anymore). 968: 970301 Fixed ncurses.c so it works with currprefs. 969: filesys_reset(): New function, called from customreset(). 970: Changed source layout. Break up machdep into machdep, osdep and 971: threaddep. 972: penguin.h: Now supports arbitrary types in pipes. 973: Changed filesys.c so that no 68k code is called from native C code. 974: filesys.asm, filesys.sh: New files. filesys.asm contains some 975: startup code and the main loop for the filesystem. Several locks 976: are allocated by the assembler code for use by the C code. 977: DOS_AllocMem(), DOS_FreeMem(), make_dev(), build_parmpacket(), 978: filesys_init(): Functions removed. 979: 970228 ncurses.c: Fix problem in b/w modes. 980: finish_drawing_frame(): Don't need to draw lines in multipenguin mode. 981: Move all options into new struct uae_prefs. New variables currprefs, 982: changed_prefs. 983: svgancui.c, tui_filereq(): If user presses a key, start search at 984: current position, not at the beginning. 985: DISK_check_change(): new function, compares currprefs with 986: changed_prefs and handles diskchanges if they differ. Called from 987: vsync_handler(). 988: DISK_validate_filename(): new function, checks whether a file exists. 989: Modify svga.c and tui.c so that F11 now brings up a limited UI. 990: 970227 Reimplement Mathias Ortmann's frame rate hack: New option HAVE_RDTSC 991: in config.h. New typedef frame_time_t. New variables vsynctime and 992: vsyncmintime. New function machdep_init() in md-*/support.c which 993: sets up vsynctime in the md-i386-gcc and md-i386-linux cases. Use 994: all of those in events.h, do_cycles() to determine whether to spend 995: more time on the CPU emulation. 996: Add missing "int i;" to xwin.c, init_colors(). 997: Unroll some loops in sample_*handler(). 998: Improve quitting/resetting behaviour: Move quit_program from GUI 999: specific files to main.c. New functions uae_reset() and uae_quit(), 1000: quit_program is now handled in vsync_handler() and m68k_go(). 1001: New variable sample_evtime, used in customreset() and set up in 1002: init_sound(). 1003: 970226 Solaris sound update from Manfred Thole. 1004: keybuf.c: Decided that it doesn't need locking after all. 1005: Add a bunch of Gustavo's latest diffs. (I hate CR characters!) 1006: Move gfxvidinfo from all the target-specific files to custom.c 1007: More Win32 stuff: New function notice_new_xcolors(). 1008: 970225 configure.in: In shell string comparisons, always put spaces around = 1009: Add warning about standard SVGAlib being incompatible with 1010: LinuxThreads. 1011: os.c, SOLARIS_SOUND: Remove reference to obsolete variable smplcnt. 1012: Two new variables sound8_base and sound16_base. 1013: sysdeps.h: Split off some stuff into md-amiga/amiga-kludges.h. Also 1014: make the main types now uae_u32 and variants instead of ULONG, etc. 1015: Convert some files to use the new types. 1016: cia.c: use int/long instead of ULONG/UWORD/etc for most static vars. 1017: xdebug.c: Some cleanup. 1018: md-i386-linux/penguin.h: Fix bug. Add "chunks" parameter to 1019: init_comm_pipe. Use it to decide in write routine whether to signal 1020: the other thread if it's waiting. Add no_buffer parameter to 1021: write_comm_pipe_int. 1022: Start adding Mathias Ortmann's Win32 patches. 1023: md-i386-win32: New directory 1024: include/sysconfig.h.win32: New file 1025: custom.c: is_lastline: new variable, set in hsync_handler(). 1026: sysdeps.h: Make it possible for system specific code to say that 1027: POSIX/ANSI stdio/malloc functions aren't present and are defined 1028: by a system-specific file instead. In filesys.c, don't reference 1029: errno if DONT_HAVE_POSIX is defined. 1030: readcpu.h: Kludge around the fact that Messysoft C apparently doesn't 1031: handle enums properly. 1032: newcpu.c/sysdeps.h: Preprocessor magic for 64 bit constants to get 1033: around a problem with MS C. 1034: md-*/penguin.h: Add dummy definitions for semaphores. 1035: keybuf.c: Use semaphores to synchronize access. 1036: os.c, win32 sound stuff: add memcpy avoidance code. 1037: 970221 X86.S: Don't use .type ifdef USE_UNDERSCORE. 1038: Move thread support configuration to configure from config.h. Change 1039: pipe implementation to use POSIX semaphore functions. 1040: 970217 From Samuel Devulder: Fix off-by-one error in LINE_TO_SCR, EHB case. 1041: 970215 customreset(): Initialize current_colors.color_regs to invalid values 1042: [reported by Samuel Devulder]. config.h: Uncomment ECS_DENISE [reported 1043: by Mathias Ortmann]. Add ami-win.c and custom.c patch from Samuel 1044: Devulder. 1045: 970213 disk.c: Set FLOPPY_SPEED to 3 1046: custom.c: SPRxCTL_1(): if spron was SPR_restart set it to 1047: SPR_waiting_start. do_sprites(): don't do that. 1048: SPRxPT{H,L}: Call decide_line(). 1049: 970210 custom.c, X86.S: Do LORES_HACK for dual playfield screens. Plug memory 1050: leak in custom_reset(). Fix pfield_draw_line() not to do so many 1051: multiplications. Make line_changed a char array. In remember_ctable(), 1052: remember comparison results also if negative. 1053: In 8 and 16 bit graphics modes, use the high parts of the color values 1054: to duplicate the actual values. This saves a lot of code in the 1055: hdoubling routines. Add a special fill_line in the X86_ASSEMBLY case. 1056: Check for glibc-2 and libpthread in configure. 1057: options.h: In fuzzy_memset(), do rounding slightly more conservative. 1058: Add tons of new keycodes to svga.c 1059: In record_color_change(), also check if vertically outside DIW. 1060: New variable hdiwstate, to represent the horizontal DIW state machine 1061: (thanks Petter!) Handled in reset_decisions(), finish_decisions() and 1062: decide_diw(). 1063: 970209 Change ncurses.c not to do so many multiplications/divisions. Add bold 1064: character support. Add color support. Make configure recognize 1065: --without-svgalib and enable ncurses.c in that case. 1066: 970208 X86.S, custom.c: Do LORES_HACK for EHB screens also. 1067: New function write_log(); convert some fprintf(stderr, ...) calls. 1068: 970207 Argh, Linux/i386/ELF check in configure got broken by latest sh-utils. 1069: In disk.c, drive_reset(), clear nodskchange flag. 1070: 970206 Sprite fix from Mathias Ortmann: _really_ get rid of SPR_vtop, and 1071: replace all uses by SPR_stop. 1.1.1.2 root 1072: 970204 Disk change fix from Mathias Ortmann. 1073: 970203 New file ncurses.c, from Samuel Devulder. 1074: Disabled Exec stuff completely. Now it isn't even compiled in anymore. 1075: 970129 Changes from Samuel Devulder for Amiga and Christian Bauer for BeBox. 1076: 970122 Reorder the set_planes_unaligned functions so that better code is 1077: generated. Remove the or_planes_unaligned functions, add a parameter 1078: do_or to the set_planes functions and rely on the compiler to optimize 1079: the additional if away. 1080: post_decide_line() can now turn DMA off early. 1081: Make struct flag_struct 64 bits large for i386 systems, so we can use 1082: long move insns without clobbering the X flag. 1083: "make clean" should delete machdep/support.o. 1084: Maybe we do need SPR_vtop after all - undo 970120 change. Instead, 1085: comment out the code that clears the pos and ctl words at vsync time. 1086: In xwin.c, restrict window height to 300 or 600 depending on linedbl 1087: mode. 1088: 970121 Get rid of SPCFLAG_BLIT, call do_blitter() directly. 1089: In finish_decisions(), don't check for sprite draws in the border. 1090: Reimplement the SMART_UPDATE define so that the memcmpy() overhead can 1091: be avoided by not setting it (but this usually loses). 1092: Detect 7 lores planes in BPLCON0() and change to 6 to avoid memory 1093: clobbers. 1094: In pfield_draw_line(), do memcpy linedoubling after handling the line 1095: to be doubled, not when we see a LINE_AS_PREVIOUS. Get rid of prev_ypos 1096: parameter. 1097: Add special code for bpldelay1 == bpldelay2 to the UNALIGNED_PROFITABLE 1098: code. 1099: In pfield_init_linetoscr(), when delays 1 and 2 differ, clear the areas 1100: which are covered only by half of the planes at the start and end of 1101: the DDF area. 1102: Replace FASTER_CPU and LINUX_SOUND_SLOW_MACHINE with M68K_SPEED. 1103: Replace fast_unaligned_memset macros with fuzzy_memset; use this also 1104: in pfield_init_linetoscr(). 1105: Use real (PAL) vblank end in do_sprites(). 1106: 970120 Mask out high byte in DDF{STRT,STOP} 1107: Oops, forgot about long frames while calculating the bounds of all the 1108: maxvpos*2-sized arrays. Increment them all by two. 1109: Try to detect empty sprites before recording them for the drawing code, 1110: but be careful not to hurt attached sprites. 1111: From Paul Kienitz: hack for keyboard code in cia.c to work better with 1112: newer Kickstarts; small cleanup in cpuopti.c. 1113: Undo yesterday's change in copper_memory_cycles(), instead call 1114: decide_line() each iteration and test whether copper_cycle_time == -1 1115: to determine whether we're vertically in the DIW. 1116: calculate_copper_cycle_time() could get astronomical plane counts due 1117: to missing masking operation. 1118: No need to put the copper to sleep for one memory cycle after a WAIT, 1119: merge that with the two cycles for the next instruction. 1120: Get rid of SPR_vtop, no longer needed (it was unnatural anyway) 1121: 970119 Implemented alternate pfield_doline functions that access the apixels 1122: array at unaligned addresses; conditional on UNALIGNED_PROFITABLE. 1123: Move LORES_HACK from config.h to custom.c. 1124: Fix loop exit test for pfield_linetoscr_hdouble_asm8(). Clear the 1125: right parts of apixels in pfield_init_linetoscr() when LORES_HACK is 1126: enabled. 1127: Get rid of bordercol array: the decision-making code should handle 1128: lines in the border correctly by setting line_changed. 1129: Disable bitplane DMA if more than 4 hires bitplanes are set in BPLCON0. 1130: Fix some more copper timing inaccuracies: used to test 1131: thisline_decision.which without calling decide_line() before. 1132: 970118 Now remember BPLCON1 changes during data fetch. New functions 1133: decide_delay(), pfield_adjust_delay(); new fields in struct drawinfo 1134: and new variables next_delay_change, delay_changes. 1135: Forgot to set copstate to COP_morewait in one case in do_copper(). 1136: Add a kludge that checks for copper position 0xDC and changes it to 1137: 0xDE. 1138: Restore equality test for vertical sprite positions. Disable sprite 1139: DMA before the end of the vertical blank area. 1140: Mask not only the positions, but also comparison values in 1141: calc_copcomp_true(). 1142: 970117 Change custom_bput to put the byte value in each half of the word that 1143: is put. 1144: 970116 disk.c: Set the gap between sector 11 and 0 to 380 words. Andromeda's 1145: "Seven Seas" demo expects at least 320. Make the KILLEHB bit 1146: conditional on AGA_CHIPSET. Decide BPLCON1 (scrolling delays) in 1147: decide_diw(). Fix off-by-one errors in the very_broken_program case 1148: of decide_plane(). Fix aspect calculation when horizontal resolutions 1149: differ. Simplify copper horizontal comparison logic slightly. 1150: Fix divide by zero errors when reading from empty floppies. 1151: 970115 pfield_draw_line(): Check for frame_redraw_necessary also for border 1152: lines. New global variable pfield_last_drawn_line, used to implement 1153: clever Y centering. Make the KILLEHB test conditional on ECS_AGNUS. 1154: Move joystick and sound initialization before gui startup. Adapt tui.c 1155: so it understands the gfx_requested_* options. 1156: We can't always avoid clearing pixdata.apixels if DIW is larger than 1157: DDF. There may be sprites in the area outside DDF, but inside the DIW, 1158: so we can't just adjust linetoscr_diw_{start,end} blindly in 1159: pfield_init_linetoscr() [Sanity Arte demo]. 1160: 970114 Bebox diffs from Christian Bauer. 1161: Support for Symmetric Multi Penguins under Linux (start second thread 1162: with clone and use some pipes for communication - rather simpleminded 1163: for now). Rework do_flush_line() and do_flush_screen() so that X 1164: libraries are only called from the first thread. 1165: Eliminate valid field from struct decision (set which to -2 instead of 1166: valid = 0) 1167: Fix definition for gui_filename() in xdebug.c to use const char * for 1168: the second parameter. Remove CRs from disk.c (now how did they get in 1169: there??). Likewise for cpuopti.c. 1170: 970113 When post_decide_line() detects mid-line DDF change, must adjust 1171: bitplane pointers in decide_plane() also. Make plfstrt the earlier a 1172: position in this case, and adjust bitplane pointers/modulos 1173: accordingly. 1174: current_hpos() isn't what GCC calls a constant function. 1175: Replace line_drawinfo[current_change_set] with new variable 1176: curr_drawinfo throughout. Likewise for new variables prev_drawinfo, 1177: {curr,prev}_{color_{change,table}s,sprite_positions}; all initialized 1178: in init_drawing_frame (). Turn line_data into a 2dim. array, do some 1179: CSE/SR on line_data[lineno] in pfield_doline_{l,h}() and 1180: decide_plane(). Make some custom registers unsigned int instead of 1181: UWORD. 1182: calc_copcomp_true(): Masking with 0xF000 isn't likely to give 0xC0000. 1183: Comment out bplcon{3,4} from struct decision. 1184: 970112 filesys.c, action_set_protect(): if __unix is defined, check whether 1185: user wants to change directory protection, and if so, force rwx to be 1186: the new protection. 1187: Force sane window sizes in xwin.c, and set width/height from mode specs 1188: in svga.c. 1189: Implement LORES_HACK compile-time option. 1190: Whee, there _are_ broken programs that enable bitplane DMA in the 1191: middle of the data fetch area, draw half a picture on the first line 1192: and the full picture on all subsequent lines. New function 1193: post_decide_line(), called from BPLCON0() and DMACON() which tries to 1194: detect this case and turns the decision from border to playfield if 1195: necessary. 1196: New arrays, sprvstart and sprvstop, calculated in SPRxPOS and SPRxCTL, 1197: and used by do_sprites. Handle sprites with vstart == vstop correctly. 1198: Sprite vpos comparisons are now done with <= , not ==. 1199: _Now_ the X86-specific linetoscr routines do their masking correctly. 1200: configure: If we have GCC, #define GCCCONSTFUNC as __attribute__ 1201: ((const)) 1202: 970111 Eliminate can_draw from struct decision. 1203: Change vertical DIW code; use enum of two states (waiting for start and 1204: for stop) which is updated in decide_line(). Lines during the wait for 1205: stop phase are decided as border. No data is fetched outside the 1206: vertical DIW. 1207: Optimize copper memory cycle calculation a little: the new variable 1208: copper_cycle_time is set to a time >= 0 if this time is constant 1209: (i.e. 2). Calculated whenever DMA, BPLCON0, or DIW state changes. 1210: blitter.c, genblitter.c, custom.c: For BLTBDAT, follow the HRM which 1211: says that immediate data is shifted as soon as it is written. This 1212: seems to be wrong for the A channel, though. Also, don't change prevb 1213: during blitter loops if DMA B is off (Sanity Arte). Turn FAST_BLITTER 1214: stuff into run-time option "-n", and eliminate the ancient blitting 1215: code (former FAST_BLITTER == 0). 1216: Big OOPS: Copper move checked copcon, but there was no COPCON function 1217: so it was always zero -> copper-controlled blitter never worked. As a 1218: speed optimization, recognize 00010000 copper commands and put the 1219: copper to sleep until the blit is finished. 1220: Slow down the blitter in decide_line() if bitplane DMA steals blitter/ 1221: copper/CPU cycles (but this code is commented out for now). 1222: 970110 New function pfield_init_linetoscr(). Move calculation of diw_end and 1223: diw_start values there from x86-specific code. Also use DDF values to 1224: determine where data in pixdata.apixels is valid. The x86-specific 1225: linetoscr routines now only do the alignment masking (and they now do 1226: it correctly, too). 1227: Got rid of the display-related contents of struct draw_info, make 1228: static variables and them initialize from pfield_draw_line() only when 1229: necessary in function pfield_expand_dp_bplcon (). Get rid of the four 1230: saved_* arrays, remember line_drawinfo instead now that it's smaller. 1231: Color compare avoidance didn't work because color_src_match didn't get 1232: set when a compare was successful. Fixed. 1233: Reorder parts of the decision-making code so that less redundant checks 1234: are performed. 1235: Add clever x centering. Change "-O" option parameter format. 1236: In md-i386-linux/support.c, memcmpy(), do memcmp() first, then switch 1237: to a plain memcpy routine once we find the first difference. 1238: Patches from Stefan Reinauer/Christian Schmitt for 1239: xdebug.c/configure.in 1240: New uae-ui.tk from Volker Zota. 1241: Add --enable-profiling to configure.in. 1242: Check for period==0 in AUDxPER() was accidentally commented out - 1243: revert. 1244: 970109 Some tweaks in X86.S, plus a new option X86_PPRO_OPT to use movzbl 1245: instead of xorl/movb when possible. 1246: Fix maxline calculation in finish_drawing_frame(). 1247: Make next_lineno always a valid array index. Decrease minfirstline to 1248: 21 (NTSC vblank end). New option -O to specify display parameters, 1249: supersedes -d and -C which will be removed eventually. Differentiate 1250: between line doubling and aspect correction. Put aspect correction code 1251: in custom.c. 1252: Remove some more unused stuff from custom.c. 1253: Fix Makefile problems when cpuopti isn't used. 1254: 970108 use_lores isn't initialized before custom_init(), setup lores_frame and 1255: friends in customreset(). Optimize spixstate clearing. Optimize border 1256: drawing with copper color changes (use fill_line instead of linetoscr) 1257: Fix the sprite DMA logic, it now works with the Interference demo. 1258: Silly bug: Sprite 7 never got displayed (introduced sometime last week) 1259: Implement USER_PROGRAMS_BEHAVE for normal (non-compiler) CPU emulation. 1260: Add most of Gustavo's last patch (new dir md-i386-dos) 1261: 970107 Finish rewriting most of the drawing code in custom.c/X86.S. See 1262: README.PROGRAMMERS and source for details. Improvements include better 1263: copper precision, better interlace support, hopefully much less bugs 1264: and not too many new ones. 1265: Remove calc_adjustment() and gfxvidinfo.x_adjust; replace with code in 1266: custom.c that looks at gfxvidinfo.follow_diwstop (new field) 1267: Some operations (like EHB playfields) now have a higher penalty than 1268: before, the assumption being that these are rare and the normal case 1269: runs faster if it doesn't have to care too much about exceptions. 1270: Fix sign mismatch bug in BPL1MOD() and BPL2MOD(). 1271: 970104 Move x_ShowEA() from xdebug.c in newcpu.c, rename as ShowEA(). 1272: 970102 Add check for XK_W to decode_es() in xwin.c. 1273: New uae-ui.tk from Volker Zota. 1274: 961218 Add a patch by Bernie Solomon to overcome a problem with K&R compilers. 1275: Change X86.S in a way that may make it either faster or slower. 1276: Fix ADF_EXT1. 1277: 961217 #ifdef XK_dead_*, since Solaris doesn't have it. 1278: 961202 Fixed joystick.h problem in configure. X11/DGA support from Kai 1279: Kollmorgen. 1280: 961117 Some fixes in svgancui.c. 1281: 961112 Gustavo's latest patch, with GUS support for DOS by Michael Sontheimer. 1282: Add menu browsing to tui.c/svgancui.c 1283: 961107 Fix m68k_areg and m68k_dreg macros (put args in parentheses) 1284: Initialize gfxvidinfo.maxlinetoscr in xwin.c (found by Sam Devulder) 1285: 961104 svgancui.c tui_refresh() routine tweaked to work with the non-standard 1286: ncurses that came with my new SuSE-Linux CD. 1287: 961031 Added Christian Schmitt's xdebug.c (disabled for this release) 1288: 961024 Module search function from Michael Krause. 1289: 961019 Add Samuel Devulder's Amiga patches. 1290: 961018 Don't use -lm on NeXTStep. 1291: 961017 configure checks for -lforms. 1292: 961016 Ian Stephenson's new NeXTwin.m. Make CLXDAT return 0 (no collisions) 1293: transdisk and transrom patches from Rodney Hester. Don't warn about 1294: 256K Kickstarts. Check diskfile sizes and try to determine whether it's 1295: a normal or a HD diskfile. No HD drive identification yet (is it 1296: different?) 1297: 961013 Corrected lots of bugs in the return address stack. Fix some errors in 1298: the compiler memory management. Use the "locked" flag for hash entries 1299: differently, and don't enforce it on a cache flush. Compile JMP to a 1300: constant address. 1301: 961012 Remove regs from cache before sign extending them for ADDA, MOVEA and 1302: similar things. Compile NOPs to nothing. Implement variable shifts/ 1303: rotates. Most shifts clear the V flag: Handle this in the compiler by 1304: some extra magic sequences after shifts or in the CC_AFTER_RO case in 1305: flush_cc_cache(). 1306: Implement a stack containing return addresses and their hash entries, 1307: and compile JSR (to constant addresses)/BSR/RTS instructions inline. 1308: 961011 compiler.c: Several bugs introduced in the last two days fixed. 1309: New function compile_note_modify() which is used when an ea is 1310: modified. This replaces calls to storeea with eaino_s == eaino_d. 1311: Bah, the 386 doesn't set flags on a NOT. Use CC_TEST_REG again. 1312: Do flag life analysis until no more changes are found. 1313: Make sure all "data" parts of EAs are locked exclusively (esp. for 1314: LEA, PEA) 1315: 961010 compiler.c: Finish yesterdays changes. Get rid of reg/offset 1316: bookkeeping in m68k_compile_block(), keep the information in struct 1317: ea_info instead. Rewrite all instructions to use the new fetch and 1318: store routines. 1319: Don't force a byteorder conversion in sync_reg() if the reg doesn't need 1320: to be written back. Don't do a SAHF or equivalent in compile_condbranch 1321: if we are doing a BRA or BF. 1322: Don't use CC_TEST_REG for NEG and NOT (this was inefficient for NOT and 1323: wrong for NEG). 1324: 961009 compiler.c: Two types of locks for registers; shared and exclusive. 1325: Implement better EA fetching and storing routines. For pdi addressing 1326: modes, lock the necessary registers shared before calling prepareea. 1327: Unlock those registers again in generate_possible_exit(). 1328: 961008 MOVEM instructions in the compiler to an absolute address could have 1329: caused random memory corruption. 1330: 961007 Spanish keyboard support for X by Ruben Martinez. Some configure fixes 1331: (don't assume current dir is in path, don't assume ncurses.h exists if 1332: libncurses does). 1333: If we're calling 68k code from an emulator function, don't use compiled 1334: code. 1335: Add a compilation option USER_PROGRAMS_BEHAVE (for compiler). Make 1336: compiler hash table larger. 1337: 961004 Fix typo in configure.in. 1338: Modify the compiler so it doesn't ever throw away code, unless it's 1339: necessary for a cache flush. 1340: Didn't quite squash the compiler flag bug yesterday. Try again. 1341: In filesys.c, do_find(), add a parameter fallback that indicates that 1342: the open should be retried with O_RDONLY if it failed with O_RDWR. 1343: Use this in find_input(). This fixes problems with r/o files on r/w 1344: volumes. 1345: 961003 Play around with the x86 specific memory access functions. Problem: 1346: __attribute__((regparam)) isn't reliable, and it seems that that's a 1347: rather hard to fix bug in GCC. Add some alternatives to 1348: md-i386-linux/memory.h; these aren't used yet though. 1349: Huh, the compiler was completely wrong about the flag needs of 1350: conditional instructions. I wonder how it could work at all... 1351: Remove a and d arrays from struct regstruct; replace with array regs 1352: with 16 elements. This allows better code for get_disp_ea() 1353: 961002 BeBox diffs from Christian Bauer. Move all code from main() to new 1354: function real_main(). 1355: 961001 Use do_get_mem_*() functions for nextiword(), nextilong() and new 1356: function nextibyte(). 1357: 960930 genblitter optimizations: Don't generate expressions in genblitter, use 1358: a second program called gengenblitter to generate a table of 1359: expressions for genblitter to use. gengenblitter knows about a lot of 1360: rules to simplify expressions. Some other tweaks to make GCC output 1361: better assembly for blitfunc.c. 1362: 960927 Turn off LED() in xwin.c (may fix SunOS joystick emulation problems) 1363: Call XFlush() and XSync() when exiting. 1364: Add some DOS patches. 1365: Add hooks in filesys.c to support filesystem units in a GUI. Use them 1366: in tui.c. Bugfixes in svgancui.c. Change the way tui_refresh() works. 1367: New option "-A". 1368: 960925 For read-only filesystems (CD...), use O_RDONLY in action_find_input. 1369: 960923 Save options file even if rename fails. 1370: Mirror address space every 16MB like we used to (got turned off by 1371: accident). 1372: Move some checks out of options.h into configure. Set up md-* 1373: directories with machine-dependent stuff in them; configure creates 1374: a link called machdep to the appropriate one. 1375: 960918 Solaris sound update from Manfred Thole. 1376: 960917 Add a timer.device replacement (buggy). 1377: 960916 Tristan Cavelier's french keyboard patch. 1378: Apply ReadTheSpecsBeforeYouWrite(tm) technology to AddPort(). 1379: Implement RemPort(), GetCC(). 1380: 960915 Tighten up some of the return values in Exec. 1381: 960914 EXEC: Implement RemTask(), ObtainSemaphoreList() and 1382: ReleaseSemaphoreList(). Set up more fields of the ExecBase properly 1383: and Enqueue it in the library list. Make InitResident call AddLibrary 1384: when appropriate (otherwise, intuition is never put into the library 1385: list). Fix major braino in Obtain/ReleaseSemaphore() (tried to Enqueue 1386: tasks into two lists). Make OpenLibrary() honor the version parameter. 1387: 960913 EXEC: Idle task now runs in user mode (abuse 0xFF0D as second STOP 1388: instruction). Make EXEC_IntTrap perform the RTE before trying to 1389: schedule. 1390: 960912 Solaris sound didn't compile. So much for making blind changes without 1391: being able to test them. 1392: 960911 As soon as you compile it under Solaris, it bombs... Now check that the 1393: hardfile exists before determining the size in main.c. 1394: execlib fixes: Set master DMA enable bit at startup, fix interrupt 1395: code to survive an interrupt that occurs before the proper SetIntVector 1396: call. Implement RawDoFmt(), CloseDevice(), CloseLibrary(), 1397: FindResident(). 1.1 root 1398: 960905 Lower 8 bits of POTGOR should be 0. 1399: 960904 Implement MULU, MULS, ADDX and SUBX in compiler. 1400: 960903 ncurses interface works. DOS people: please use the new portable tui.c 1401: and turn dos-ui.c into a frontend for conio.h, similar to svgancui.c 1402: In xui.c, unlink the temporary files ASAP. 1403: Two new command-line options, "-o" and "-G". 1404: Get rid of sz_unknown. 1405: compiler.h, compiler.c: New files. 1406: filesys.c, action_read(): Added a hack to test whether the first four 1407: bytes read from a file a file contain 0x000003F3 (HUNK_HEADER), in 1408: which case there's probably a LoadSeg() call going on and we ought to 1409: flush the cache. Also, use the fact that memory is now linear. 1410: 960902 Struggle a bit with dos-ui.c, rename it to tui.c (text-based ui), add 1411: new file svgancui.c (ncurses ui) and try to make these two understand 1412: each other. 1413: 960829 New transdisk from Stefan Ropke (can write images) 1414: Apply Patrick Hanevolds BeBox patches. 1415: 96082x many changes to Exec. Still not booting (DMACON seems not to be set up 1416: properly, and sometimes Signal is called with task==0). 1417: 960821 Solaris sound from Manfred Thole. 1418: 960820 In filesys.c, get_fileinfo(), return volume name for top-level 1419: directory. 1420: 960819 Reimplement WritePixel(). Layer locking is still missing. 1421: 960818 Reverse meaning of -x flag for X11. More Exec code. 1422: Several changes to the main CPU loop and the way call traps work. 1423: 960817 Implement some simple Exec functions (Lists, AllocMem & friends) 1424: 960816 filesys.c fixes from David Varley. 1425: 960815 Implement graphics library region functions. 1426: 960814 Modify memory layout: All memory is linear now; get_real_address() 1427: returns a (UBYTE *). 1428: 960810 Add Gustavo's latest DOS code. 1429: In configure, include <sys/param.h> earlier for the sake of some *BSD. 1430: Add three options for sound code (bits, frequency, buffer size). 1431: Make -S option take a parameter; remove SPEED_UP_SIDMON_MODULES. 1432: New version of transrom (return 0, duh). 1433: 960805 Fixed the blitter line mode emulation (this time, really! I hope.) 1434: Thanks to Fabio Ciucci for a detailed description of the correct 1435: behaviour. 1436: 960730 Spent the last three days trying to make the filesystem emulation 1437: bootable by adding an expansion device for it. A fair bit of trial and 1438: error, but now it works! Even the hardfile now works with Kick 1.3, but 1439: you have to mount it manually after booting. 1440: hardfile.c, filesys.c, expansion.c and autoconf.c now are an 1441: entangled mess which badly needs to be cleaned up. 1442: We can now mount more than one filesystem even with Kick 1.3: we 1443: recognize them by param 2 of the startup packet, which has the same 1444: value as the dn_Startup field of the devicenode. 1445: Make Kickstart replacement work again (didn't like the CPU emulator 1446: changes) 1447: Include preliminary serial support from Stefan Reinauer. 1448: 960728 Fixed the scancodes for <> and #' keys in svga.c 1449: Apparently, CIA timer latches ought to be 0xFFFF after a reset 1450: (prevents Eagleplayer from crashing occasionally). #ifdeffed out a 1.1.1.2 root 1451: slightly weird call to INTREQ from RethinkICRB() 1.1 root 1452: 960727 Sound code rewritten again. Now uses events (five new ones). All 1453: modules seem to play correctly now. It's a bit slower, though. 1454: AF sound should work again, patches from Marcus Sundberg. 1455: 960723 ... and more CPU emulation bugs fixed by Herman. 1456: Added uae.library from Tauno Taipaleenmaki, plus support files in the 1457: "amiga" directory. 1458: Added some files for the XFree86/OS2 port from Krister Bergman. 1459: Reorganized all the directories. 1460: 960717 Add latest patch from Herman. 1461: More FAST_BLITTER options: 4 and 5. These finish the blit immediately. 1462: 960713 Call XAutoRepeatXXX() only if we know we want to change the state. 1463: 960709 Work around a few AIX bugs (ughhh... what a broken OS). New test for 1464: sys/select.h. 1465: In xui.c, don't try to communicate with a dead process. 1466: 960704 More bugfixes from Herman. 1467: Get rid of dummy_xlate(), use default_xlate() to abort with error. 1468: In svga.c, set correct_aspect to 0 if using lores. 1469: Change the Bcc exception 3 handling code a bit. 1470: Add new program "cpuopti" that takes gcc-generated assembly files and 1471: optimizes away unnecessary pushl/popl instructions on the x86. 1472: 960701 68020 exception handling & various bugfixes from Herman ten Brugge. 1473: In ersatz.c, use 0xFF0D instead of 0xF00D as trap opcode. 1474: Do MMU "emulation" (no-op MMU instructions, probably many cases decoded 1475: incorrectly). 1476: 960627 New file LIESMICH, with minimal German instructions. Somebody want to 1477: translate the docs to French, Spanish, Italian, all the Scandinavian 1478: languages, Hebrew, Polish, Dutch, Russian, Welsh, Gaelic and something 1479: [email protected] understands? (No offense meant - I'm sure there are 1480: brillant minds using AOL. There must be.) 1481: 960626 In zfile.c, make sure we delete the temporary file even if file 1482: decompression fails. 1483: Reimplemented sound support, this time following the HRM closely. Seems 1484: to work fine most of the time, but occasionally loses drum beats in 1485: TFMX modules. do_sound() is now unconditional, it calls 1486: flush_sound_buffer(), which is system-dependent. This breaks everything 1487: except Linux sound for now :( 1488: Add Herman ten Brugge's 68020/68881 emulation code. 1489: FreeBSD chokes if sys/mount.h is included without sys/types.h. Fix the 1490: configure script. 1491: 960622 More work on AGA code. 1492: Removed 2-bit display routines from custom.c. Ian: please use dithering 1493: code. 1494: Make slowmem and chipmem sizes run-time configurable. 1495: Mask out the high bits in BLT?PTH(). 1496: Add exception 3 checks to Bcc/BSR instructions. Seems to be not quite 1497: correct yet. 1498: Completely rewrote the disk emulation. We now create a big track buffer 1499: full of MFM data, used in a cyclic fashion by DSKBYTR() and friends. 1500: The current position in the buffer is determined by the cycle counter. 1501: DMA reads are now done in one piece. Two new event types: ev_diskblk 1502: and ev_diskindex. 1503: ARRGGHH! The RSI demo has _completely_ broken disk loading routines. 1504: They start disk DMA on a block while the blitter is still working on 1505: the same memory region. 1506: In zfile.c, unlink() the temporary file directly after opening it so 1507: it will be freed by the OS as soon as we close it (or crash... :) 1508: 960621 Merge pfield_sprite_h() and pfield_sprite_l() into one function. 1509: Split off new files blitter.c and blitter.h from custom.c. 1510: Fixed null-pointer dereference in zfile.c when filename has no 1511: extension. 1512: Add new field maxline to gfxvidinfo that prevents writing past the 1513: screen buffer if it has less lines than expected. 1514: Modify the 256 color allocation routine to set nb_cols to the same 1515: value first for r,g and b; allocate everything as usual and fill the 1516: lost colors afterwards with those that have the greatest difference. 1517: 960620 For some extremely weird reason, it is faster to simply call the 1518: assembly-optimized pfield_linetoscr_full routines _twice_ to double the 1519: line than calling the new (also assembly-optimized) 1520: pfield_linetoscr_full_double routines, at least when writing directly 1521: into the framebuffer. If someone has a good theory why, let me know 1522: about it. 1523: Drawing into memory is faster with the _double routines, but not 1524: noticeably (about 1%). 1525: Consequence: Removed the new pfield_linetoscr_full_double assembly 1526: routines again. 1527: Add a "--disable-gui" option to configure. 1528: Add Samuel Devulder's dithering code. Provide support for mono and 1529: 16 color X servers. 1530: Put an assembly version of DitherLine() in X86.S. 1531: New color mode (3) available, tells UAE to use 256 colors and dither 1532: the image. This is meant for people who have only a 256 color X server 1533: available, but it works with the SVGA version, too. It's much slower 1534: than normal 256 color mode, though. 1535: Use the color allocation algorithm from the dither code in 1536: alloc_colors256(), too. 1537: 960619 New files: zfile.c and zfile.h, from Samuel Devulder. These provide 1538: transparent decompression of various compressed file formats. Enabled 1539: by configure only for Unix systems. 1540: Eliminate dont_want_aspect. New option "-C", sets correct_aspect. Make 1541: video mode 3 640x480, video mode 4 800x600. Honor correct_aspect in 1542: 320x400, 640x480 and 800x600 mode with SVGAlib. 1543: Add fields maxlinetoscr and x_adjust to gfxvidinfo. 1544: Rename pfield_slow_linetoscr() to pfield_do_linetoscr(). Use new fields 1545: in gfxvidinfo to enable writing directly to the framebuffer in 1546: resolutions with <800 horizontal pixels. 1547: New function pfield_do_linetoscr_full(), called when sure that full 1548: line update is being done. 1549: Move some of the usage() information into some target_specific_usage() 1550: functions, defined in the various system-specific files. 1551: Support lower resolutions with LOW_BANDWIDTH, too. 1552: memcpy() within screen memory is dog slow. Prevent some common cases: 1553: 1. Use fill_line() to double a line in the border. 1554: 2. Add a parameter to pfield_do_linetoscr_full() to indicate whether 1555: the line has to be doubled. New functions 1556: pfield_linetoscr_*_double_slow() that simply do a memcpy(), plus 1557: optimized ones in X86.S that are much faster by avoiding the copy. 1558: Smart update code could get confused by lores modes when 1559: prev_max_diwstop changed from one frame to the next. New variable 1560: frame_redraw_necessary, which acts as a counter. It's initialized to 1561: 2 in interlace mode to handle that case properly, too. 1562: Move sprite priority checks into pfield_sprite_?(), move HAM 1563: calculations into new function decode_ham6() to simplify the various 1564: linetoscr functions. 1565: Fixed a bug that would cause sprites to get deformed in some cases 1566: when they overlapped (never seen it). 1567: 960618 New file: dos-snd.c, from Gustavo. 1568: 1569: 960617 Release 0.6.0 1570: 960617 Fix memory clobber in X86.S when diwfirstword==0. Eliminate double test 1571: for HAVE_SYS_MOUNT_H in sysdeps.h. 1572: 960616 Handle programs that don't wait for the blitter by finishing a pending 1573: blit as soon as a blitter register is written to (regardless of DMACON, 1574: to be safe). 1575: Call gui_led only if the LED changed. 1576: 960615 Fixed dual playfield sprite priorities. Optimized dual playfield code 1577: in X86.S. More work on AGA code. Get joystick status only in 1578: vsync_handler to speed things up. 1579: Make blitter fill more intelligent with table lookups instead of loop. 1580: 960614 DOS update from Gustavo. Pass real bitplane pointer to 1581: bpl_data_differs(), don't calculate it again. 1582: 960610 Fixed silly INTEL_FLAG_OPT bug: The new __asm__ expressions use 1583: regflags, which is of course _regflags on a.out... 1584: More BeBox fixes from Christian. 1585: Make the CIA bank bigger (A0..BF) and relax the CIA A/B selection 1586: checks to make broken software (Kingsoft's Emerald Mine, reportedly) 1587: happy. 1588: Default framerate is now 1. 1589: 960603 New BeBox code from Christian. Fix test for ELF in configure.in. 1590: 960529 genblitter.c: generate blitfunc as a function taking ULONGs and 1591: returning an ULONG. This makes custom.o about 4500 bytes smaller on the 1592: x86 by removing worthless size prefixes, and should increase 1593: performance (better for the cache, and the P6 reportedly doesn't like 1594: 16 bit instructions anyway). 1595: memory.c: Load Kickstart in one block and swap bytes after that if 1596: necessary (eliminates the need for the special bebox load routine) 1597: custom.c: Some preliminary work for AGA support. 1598: 960528 Saw a real awful piece of code that detects the right mouse button by 1599: reading a value from POT0DAT, counting up to 25, reading from POT0DAT 1600: again, and deciding the button is pressed if the value changed. Urgl! 1601: Added POT0DAT() in custom.c ... 1602: Gustavo's latest patches. 1603: 960525 Do index pulse handling in CIA_hsync_handler(). Make sure bit 12 in 1604: INTREQ gets set on an index pulse. Don't call DISK_Index() for now, 1605: since this breaks the Workbench. 1606: The CIA code should _probably_ not be resetting the bits in INTREQ. 1607: Disable this as an experiment, let's see what breaks. 1608: 960524 Z flag handling for ABCD/SBCD/ADDX/SUBX was wrong (must be clear if not 1609: zero, was set if zero). Some other flag bugs in these functions fixed. 1610: 960523 gfxlib.c update from Christian Schmitt. Some new Mac code from Ernesto, 1611: still not all of it, though. Italian keyboard from Alessandro Bissacco. 1612: 960522 Fix the CHK instruction. Implement middle mouse button. 1613: 960515 Fix some Nextstep problems in configure.in. 1614: 960513 New Makefile target "streifenfrei" to remove all output from configure. 1615: Use autoconf 2.7; 2.9 is buggy. 1616: 960512 Remove BIG_ALIGNMENT hack. Remove superfluous pfield_fetchdata() call 1617: in pfield_doline_slow_l() that resulted in garbage on the screen. 1618: Move blttbl array from custom.h to genblitter.c 1619: Use new lookup tables imm8_table and areg_byteinc in CPU emulation 1620: instead of ?: expressions. 1621: GCC appears to generate better code if the opcode is passed as ULONG to 1622: the CPU emulation functions instead of as UWORD. 1623: Modify some of the flag emulation __asm__ statements so that GCC uses 1624: less registers for them. 1625: 960510 Cast malloc() results to char *, for C++ compilers. 1626: 960509 Use test for GCC and __i386__ in options.h to decide whether to use 1627: intel flag optimization. 1628: Use test for wish4.0 to decide whether to use the GUI. 1629: 960507 New bebox.cpp from Christian. AF sound patches from Marcus Sundberg. 1630: 960505 Fix the configuration stuff so it works. Fix some bugs in gfxlib.c 1631: 960504 Use GNU autoconf scripts to generate Makefile and sysconfig.h. Add new 1632: files sysdeps.h that includes the right system header files. Remove 1633: amiga.h and Makefile. 1634: 960502 More Next code from Ian (new Uae.app directory, 2 bit drawing for 1635: custom.c). 1636: 960501 Allow the sound driver to set the frequency to a value that is slightly 1637: different from the requested one. 1638: 960430 Added AmigaOS port from Olaf Barthel. 1639: 960427 Fixed single playfield sprite priorities in X86.S. 1640: 960426 Added new NeXTwin.m from Ian. 1641: Turn off the blitter delay in line mode. 1642: Added a CPU optimization from Olivier Raoul: gencpu now reads a file 1643: "insncount" that can be generated by UAE during execution and generates 1644: specific functions for the most common opcodes. Not documented yet. 1645: 960414 Reimplemented the fast disk emulation in a more sane way. Also it's 1646: only done for reads now. (Plus, it no longer works :-/ Need to work 1647: some more on this). 1648: In blitter emulation, defer not only the setting of the bltfinish bit, 1649: but actually defer the whole blit for the number of cycles it will 1650: take. This makes programs the clear the screen while it is still being 1651: displayed look much better. 1652: Changed supervisor mode handling around a bit (was messy). 1653: New DOS code from Gustavo. 1654: 960412 Removed smart update method 2. Added Alessandro Bissacco's blitter 1655: optimization patch. 1656: Fixed some sprite problems: during hysnc, clear sprpos and sprctl, and 1657: don't do_sprites() in line 0. 1658: 960409 Be a little more intelligent about when to call pfield_linetoscr() from 1659: pfield_doline_slow(). It's only necessary if a color register changed. 1660: If it can be deferred to the end of the line, use the the _full 1661: variants. 1662: Some CIA TOD fixes. 1663: Better transdisk, accepts first/last track parameters. 1664: 960405 New function memcmpy(), inline assembler for the i386. Compares two 1665: memory blocks and copies them at the same time. Used in 1666: bpl_data_differs. 1667: 960404 French keyboard from Tristan Cavelier. Parallel port emulation from 1668: Stefan Reinauer. 1669: Turn bpl?pt and r_bpl?pt into arrays, simplify some code using them. 1670: 960401 Some parts of Ernesto's new Mac sources. 1671: 960331 filesys.c: Close filedescriptors in free_key(). get_path() sometimes 1672: read uninitialized bytes. 1673: Minor cleanups all over the place. 1674: unchain_mnn() leaves sibling intact, but clobbers next. customreset() 1675: didn't care about that and crashed. 1676: Use the __asm__("intel_flag_lookup") magic not only for DOS. 1677: Support 320x300 for X (without LOW_BANDWIDTH). 1678: Add new function fast_memcmp(), defined as memcmp if __i386__ is 1679: undefined, otherwise a slightly optimized inline assembly function. 1680: 960329 Some bug fixes in gencpu.c 1681: 960328 Stupid programs write odd playfield modulos into the hw registers... 1682: Eek! Sometimes, linedescr[] was indexed with a negative value... Add a 1683: vpos >= minfirstline check to pfield_may_need_update(). I really need 1684: to rewrite this in Oberon... 1685: Don't turn off SHM when LOW_BANDWIDTH is selected. 1686: Keep the nextpos and linepos variables from pfield_doline_slow_?() as 1687: globals and initialize them in pfield_may_need_udpate(). 1688: Modified alloc_colors256() some more. 1689: Try to make sprite DMA follow the Amiga DMA slots more closely by 1690: adding a currhp parameter to do_sprites() and calling it at the end 1691: of a scanline or in pfield_may_need_update(). 1692: 960327 Added Gustavo's latest DOS code, as far as possible. Modified X86.S to 1693: use a macro SYM() to create symbol names either with underscore or 1694: without. 1695: Fixed some very silly SVGAlib lores bugs. Move screen 8 pixels up in 1696: low resolution. 1697: Use diwstop instead of diwstart to caclulate the DIW for 320x200 modes. 1698: Reset it not only in calcdiw(), but also in init_frame(). 1699: Speed up 256 color allocation a little bit. 1700: 960326 New function flush_block() in xwin.c and svga.c. Called from 1701: do_flush_line() and (new function) do_flush_screen(). Modify struct 1702: vidbuf_description, new member maxblocklines that records the maximum 1703: number of scanlines that do_flush_line() should collect before calling 1704: flush_block(). If it is zero, then flush_line() is used as before. 1705: This makes the special case stuff for SHM unnecessary, so it's removed. 1706: Fixed a stupid bug in events code: Put ev_hsync in front of ev_copper, 1707: so that do_copper gets called with hpos == 0 instead of hpos == 227 at 1708: the beginning of the line. 1709: New function init_frame() that sets up some variables, called from 1710: customreset() and vsync_handler(). 1711: Move smart update code to pfield_doline() from pfield_doline_h() and 1712: ..._l(). Clean up these two with a macro DO_ONE_PLANE, removing 1713: duplicate code. 1714: Implement big blits and ECS chip ids. New configuration options 1715: ECS_AGNUS and ECS_DENISE. 1716: Implement MOVEP. 1717: 960325 Before calling pfield_may_need_update(), make sure the value that was 1718: written to a register actually differs from the previous one. 1719: New expansion code from Stefan Reinauer. 1720: Modify struct mem_notify_node to contain a pointer to a valid bit 1721: instead of the valid bit itself, so that the playfield code has to 1722: check only one flag to decide whether to draw the line (SU method 2) 1723: 960324 The chip_flags approach has several problems. A flag may cover an area 1724: in memory that spans two scanlines, or several scanlines may use the 1725: same area in memory. 1726: Provide two other, different methods for the smart update: 1727: 1. Save all the bitplane data for each line and compare the chipmem 1728: with the saved data to decide whether an update is necessary. 1729: 2. Use a chain of memory_notify_node structs instead of a single bit 1730: for flags. Each scanline owns a set of these structs and chains them 1731: into the right place, and the chipmem_?put routines walk the chains 1732: and set the modified bit for each element. 1733: Unfortunately, both methods are slower than the old one. Especially the 1734: first one has some advantages though: it speeds up programs that clear 1735: the screen each update and write the same contents back, and it 1736: can speed up double-buffering programs at full framerate, since it does 1737: not have to check whether the bitplane pointers have changed. 1738: Remember the first and last drawn line for each frame, and pass them to 1739: flush_screen. Use this in xwin.c for SHM. Modify SHM logic: if smart 1740: update is selected, call XShmPutImage() from flush_line() instead of 1741: from flush_screen(). But gather blocks of consecutive lines to avoid 1742: calling XShmPutImage() too often. 1743: 960323 "Smart update" method, based very loosely on Alessandro Bissacco's 1744: work, implemented: 1745: Add an array chip_flags that records any change made to specific words 1746: in chip memory. 1747: Move all the hardware registers relevant to playfield display into a 1748: new structure bplinfo. Remember the contents of this structure in 1749: struct line_description for every line on the screen. Avoid redrawing 1750: in pfield_doline if the screen memory has not been modified for the 1751: line to be drawn and if the information from the last frame matches 1752: that in the current frame. 1753: 960322 Duplicate all functions responsible for drawing (pfield_doline, 1754: pfield_doline_slow, pfield_sprite, pfield_*word_*res) and append _h 1755: or _l (ah, the golden C++ days, when we had templates... which never 1756: worked). Modify the *_l functions to support drawing in low resolution 1757: (i.e. 320x200). Change the options -d and -H to support selecting color 1758: mode and resolution, thereby getting rid of some SVGALIB_* options. 1759: Get rid of the old pfield_*word_*res functions. 1760: Collect information about the minimum diwstart value during the 1761: previous frame and use that in case 320x200 was selected to fit the 1762: image on the screen. 1763: Get rid of HAVE_JOYSTICK (breaks the "-J" option) 1764: 960321 Give up in op_illg() if opcode is 0x4e7b and the exception handler for 1765: it is NULL. In that case, it's a 68020 Kickstart. 1766: 960319 New Next code from Ian. SunOS target was still screwed (two CFLAGS). 1767: Turn -x option into a "hair cursor" option. Support multiple mounts, 1768: but warn if more than one is seen (still does not work with Kick 1.3). 1769: Integrated Samuel Devulder's new LOW_BANDWIDTH patch. 1770: 960318 Integrated the start of Markus Gietzen's gfx library replacement. 1771: Changed the interface between custom.c and the graphics code. There has 1772: to be a buffer holding the data of all the lines on the screen. For 1773: linear SVGAlib modes, this is the video memory. Eliminated -x option, 1774: prepare_line(), DrawPixel() and the X_?BIT_SCREEN options, replace with 1775: 3 versions of pfield_linetoscr for different datatypes. Implement 1776: proper handling of the borders above and below the DIW in custom.c 1777: instead of in flush_screen(). 1778: Move common code (color allocation) from all the graphics files to new 1779: file gfxutil.c. 1780: Swedish keyboard from Per Olofsson. 1781: 1782: 960315 Release 0.5.0 1783: 960315 Newest DOS port from Gustavo. New sgi-gcc target. 1784: 960314 Add -lXext to osf target. Use "rb" for fopen() in main.c 1785: 960310 Play a bit with the __asm__ constraints. Implement CHK. 1786: 960307 Fix some stupid Makefile errors. Call parse_cmdline() if no init file 1787: is found. 1788: First round of NextStep patches; new file NeXTwin.m 1789: Stupid bug in custom.c: The #define is called NO_FAST_DISK, not 1790: NO_FAST_FLOPPY. 1791: Fix one of the problems the Deform demo had with the blitter: The 1792: line texture wasn't rotated to the right position in blitter_init(). 1793: 960306 Use some black GCC __asm__ magic to calculate flags more quickly 1794: (config INTEL_FLAG_OPT) 1795: HAM was broken by pfield_linetoscr changes. Fixed. 1796: LOW_BANDWIDTH sometimes got confused when the display window changed. 1797: 960305 BCD instructions work well enough for Locomotive Basic on CPE. 1798: New function parse_cmdline_and_init_file() that reads ~/.uaerc or 1799: ./.uaerc and adds the options found in those files to those in argv[]. 1800: Patch from Denis Sablic to make disk image filenames runtime 1801: configurable. Extend it for the ROM filename. 1802: Remove some of the run-time configurable stuff from config.h. 1803: More X keysym fixes (I finally got a proper .Xmodmap ...) 1804: for SVGAlib: Delete key, and PgUp/PgDn as Amiga keys. 1805: The sound driver can now handle 22050 Hz and/or 8 bit samples. Both of 1806: these are the default with LINUX_SOUND_SLOW_MACHINE. 1807: Also use the SNDCTL_DSP_GETBLKSIZE ioctl and write the buffer when 1808: there is enough data. 1809: Abuse keybuf.c to provide a fake joystick emulation with the numeric 1810: pad (enable with -J) 1811: 960304 bebox.cpp from Christian. 1812: Rename pfield_linetoscr_full to pfield_linetoscr_full8. 1813: More x86 assembly: pfield_linetoscr_full16. 1814: 960303 SunOS target from Dirk Vangestel. Put some not-so-superfluous includes 1815: back in. Added the DOS specific patches to filesys.c. 1816: Started x86 assembly optimizations. New file X86.S, includes an 1817: optimized version of pfield_linetoscr (for 8 bit screens only). 1818: Don't use SA_RESTART if it isn't defined. 1819: prepare_line() wasn't called often enough (again...), leading to memory 1820: corruption and "hit the reset button" bugs when using SVGAlib. 1821: 960226 Get rid of bool, true and false in amiga.h and everywhere else. 1822: Copy yesterdays code to AF_SOUND code, too. 1823: Include first round of Christian Bauer's BeBox patches. Add AIX fix 1824: from Samuel Mackrill. 1825: Add #include <string.h> and #include <stdlib.h> in some more places. 1826: Modify gencpu.c and readcpu.c so that immediate types j and J (0..15 1827: and 1..8) can be merged. Replace HAVE_ONE_GIG... option with a new 1828: CPU_EMU_SIZE option that can be set to a value in the range 0..5, 1829: where 0 is minimum size and 5 is equivalent to HAVE_ONE_GIG... 1830: 960225 Remove multiplications in sound code, use a big lookup table. 1831: 960222 Go back to having only one memory bank table of type addrbank instead 1832: of several function pointer arrays. Eliminate the HAVE_BROKEN_SOFTWARE 1833: define by extending the memory bank table to 65536 entries. 1834: Remove remaining DUALCPU code. Allow BTST src,imm instructions in 1835: table68k. 1836: 960220 Back out filesys.c change from Stefan Reinauer: don't call V36 specific 1837: functions in expansion.library. 1838: Better fix for the filesys.c assign problems by Oliver Moehrke. 1839: Make new playfield code conditional on EXPERIMENTAL_SCREEN_UPDATE. 1840: Improve the 64bit variant of said code. Try to get alignment for 1841: apixels by putting it into a union with a long. 1842: Kill the child in gui_exit(). Make graphics_init() return a value and 1843: check it in main.c to see whether graphics were initialized. If not, 1844: call gui_exit() anyway. 1845: Use new 256 color allocation routine from svga.c in xwin.c, too. 1846: Make LOW_BANDWIDTH compile _and_ work (wow...). 1847: 960219 Fix bug in memory.c: When loading 256K Kickstart, copy 256K, not 128K. 1848: 960218 Finished the rest of the UI: reset, debug and quit buttons as well as 1849: drive LEDs. New target linux-gui; all others use dummy file nogui.c 1850: for now. 1851: 960217 The GUI now supports inserting and ejecting diskfiles and displays 1852: their names. Two pipes are used now, one for reading and one for 1853: writing. Properly wait for the process to start up. 1854: Use sigaction() instead of signal() in debug.c. 1855: More fixes for the new display routines: Need to do a final call to 1856: pfield_*word_*res with the data shifted right from the last fetched 1857: word. 1858: 960216 Copper & sprite bugfixes from Marco Nelissen. Better X keyboard support 1859: from Bruno Coste. 1860: Move my_strdup() from filesys.c to options.h 1861: New files xui.c, uae-ui (shell script) and uae-ui.tk (wish script). 1862: These create a GUI for the X version of the emulator. So far, the 1863: power LED works. 1864: 960215 Don't rely on SVGAlib headers defining any keycodes at all. 1865: Include Thorsten Frueauf's NetBSD patch. Apparently, the devname 1866: variable in hardfile.c caused a namespace collision, so rename it to 1867: uaedevname. Fastmem fixes, debugger help, and ConfigDev allocation in 1868: hardfile and filesys from Stefan Reinauer. 1869: xwin.c: Give the window a title. 1870: Half-implemented the DIVU.L, DIVS.L, MULU.L and MULS.L instructions. 1871: 960213 AF sound system support from Marcus Sundberg. Win95 keyboard support 1872: for SVGAlib from Thierry Lescot. Added most of Gustavo Goedert's MS-DOS 1873: port. 1874: When using the old pfield_*word_*res functions, the gen_pfield_tables() 1875: function was undefined. 1876: Hmmm, /dev/brain must have been unmounted when I wrote the new pfield_* 1877: functions. Now they make sure they access the apixels array only with 1878: addresses that are multiples of 16 bytes. 1879: 960212 Fix copy&paste bug in cia.c found by Marco Nelissen: Need to call 1880: RethinkICRB() instead of RethinkICRA() for CIA B timers. 1881: Added Stefan Reinauers autoconfig area/fastmem support. Added run-time 1882: options for use_slow_mem and use_fast_mem. 1883: Oops, the pfield_*word_*res() optimizations break completely on HPs and 1884: Sparcs. Now use this optimization only if we are using GCC 2.7. 1885: HPUX fixes in the Makefile. New target hpux-gcc. 1886: The code for clearing the areas above and below the DIW was trying to 1887: be a little too clever selecting the color. Just use the current 1888: background color. 1889: Added channel attachment to the sound code. Untested. 1890: 960211 Found some flag setting bugs in the rotate/shift instructions and in 1891: addx/subx (which I thought I had already fixed) by reimplementing 1892: DUALCPU mode to work with Ed's e68k. 1893: Argh! The copper is completely disabled during DDF in Hires 4 bitplane 1894: mode - so copper positions 0x30 and 0x34 are about 640 pixels apart. 1895: The Kickstart uses FF39FFFE to wait for the end of line 256 instead of 1896: FFDFFFFE as in all the other modes. This is implemented now, but 1897: probably not 100% correct. 1898: Added check whether SVGAlib doesn't support our mode. 1899: If using GCC >= 2.7, define __attribute__((aligned(16))) as 1900: BIG_ALIGNMENT in config.h. Use it for the apixels array to prevent 1901: potential problems on the Alpha. 1902: Tried to make the color selection routine produce better results in 256 1903: color mode. 1904: 960210 readdisk didn't work at all for large files - fixed. 1905: In pfield_doline(), clear the apixels array if playfield DMA is off. 1906: In SPRxCTL(), reset sprite mode when sprpos==sprctl==0 1907: Rewrite pfield_orword_hires() and friends to use lookup tables. No 1908: noticeable improvement on my machine, but might be different on other 1909: machines. Two versions of this code: one using 64bit longs on the Alpha. 1910: New targets linux-debug and linux-prof. 1911: Use 1MB slow mem. 1912: -funroll-loops is a little excessive. Remove it. 1913: Add support for linear addressing modes for SVGAlib version. Speedup 1914: is 20-30% on my old 486 VLB. Now, would someone please fix SVGAlib to 1915: support that for the S3-864 as well? 1916: Set SVGAlib keyboard mode to DONT_CATCH_CTRLC. 1917: Change custom.c, xwin.c and svga.c to keep track of the display window 1918: and background color and to clear the areas above and below the display 1919: window if necessary to remove garbage images from previous frames. 1920: Set the LOF bit in the Kickstart replacement init routine. Also 1921: initialize CIAs to Kick 1.3-like values. 1922: 960209 Some more -DHAVE_xxx_H options in the Makefile and filesys.c. DEC Alpha 1923: fixes for filesys.c from Ed and Marcus. HPUX fixes. 1924: New field in table68k for CPU type, parsed by readcpu and compared to 1925: CPU_LEVEL which is defined in config.h. New instructions MOVE2C, MOVEC2 1926: and CAS. Also a new field for priviledge level that is used by gencpu to 1927: generate tests for regs.s and Exception(8) calls if necessary. 1928: Move parsing of table68k into a new file build68k.c. Generate a file 1929: called cpudefs.c containing the information from table68k in 1930: machine-readable form. Change readcpu.c to use the array found in 1931: cpudefs.c. 1932: Don't generate the d8(An,Dn) addressing mode in-line. Generate a call to 1933: get_disp_ea(), which is an inline function in newcpu.h if UAE is 1934: configured for 68000 emulation; for 68020 emulation, it is defined in 1935: newcpu.c. 1936: Debugger could crash on illegals because there was no mnemonic defined 1937: in lookuptab[]. 1938: Return zero for SERDATR. 1939: 960207 It seems that the copper stops completely if an attempt to write to a 1940: specific register fails because of COPDANG. Apparently, the Kickstarts 1941: use this to stop the copper with a 0x00000000 longword. This leaves the 1942: question why they don't do 0xFFFFFFFE like everybody else. 1943: Enable 512K slow memory by default. 1944: Integrate Stefan Reinauers battclock patch that makes it work with 1945: newer Kickstarts. 1946: In cia.c, do the little index pulse hack even if dskdmaen==1, because 1947: DMA is only enabled when dskdmaen==2 (Helps the "Mad Decision" demo). 1948: Add solaris entry to Makefile (GCC, Openwin, -DHAVE_STATFS_H) 1949: Define HAVE_STRINGS_H for SGIs, change filesys.c accordingly. 1950: 960206 Build a smaller table instead of cputbl.c. Use readcpu and the smaller 1951: table to build the cpufunctbl array at run-time. 1952: Nuked the other half of the old CPU emulator. Reimplemented debugger to 1953: use the information generated by readcpu. 1954: Define HAVE_STATFS_H for SGIs in the Makefile, and use that as a test 1955: in filesys.c instead of #ifndef __linux. 1956: Hack filesys.c, get_path() to support the assign command. 1957: Add -fstrength-reduce and -funroll-loops in Makefile to make people 1958: nervous. 1959: Rewrite Sam Devulder's LOW_BANDWIDTH patch and add it to xwin.c. 1960: 960205 Forgot some PC-relative bit instructions in table68k. 1961: Nuked half of the old CPU emulator. 1962: Split gencpu.c into two parts, new one is called readcpu.c and just 1963: parses the table68k file. Link it to the main program. 1964: 1965: 960205 Release 0.4 1966: 960203 filesys.c, action_read(): Slightly more efficient code (translate Amiga 1967: address to real pointer). 1968: Moved some common code in the generate_* functions in gencpu.c to a 1969: separate function. 1970: 960202 Added an experimental fast disk option. Currently turned off by 1971: default (it's not such a big win). 1972: Attached sprite fixes (overlapping att. sprites looked bad, Katakis). 1973: Add sleep(1) before resetting the console to text mode when using 1974: SVGAlib: this might fix some screen corruption problems. 1975: Add sprite/playfield priority checking to the most important case 1976: (single playfield, no HAM). 1977: In filesys.c, do_find(): open() returns -1 on error, not zero. 1978: Return ERROR_OBJECT_WRONG_TYPE if do_find() is called for a directory 1979: (fixes Champions of Krynn harddisk installation). 1980: 960201 Don't abort if sound driver not present, just set produce_sound to 0. 1981: New files keybuf.c and keybuf.h to record keypresses in the right 1982: order and without losing any. In cia.c, force 15 scanlines between 1983: keypresses, just to be sure. 1984: unixfs.device _does_ work with Kick 1.3: just don't trust what Kick 1.3 1985: sends in the startup packet. For now, disable more than one mount per 1986: command line. 1987: Started integrating Ernesto's new Mac sources. 1988: Remove superfluous includes from some files. 1989: 960131 Added Ed's unixfs.device (great stuff). 1990: Adding ULONGs to pointers is a bad idea on the Alpha if the ULONG value 1991: really is signed. Add some casts to LONG in (pc_p + src) expressions 1992: in genpu.c. 1993: If DMACON is written and copper DMA is enabled, do a COPJMP1 at once. 1994: Helps the "Interference" demo. 1995: 960129 More SGI fixes from Ed. Bugfixes and transdisk improvements from Marcus 1996: Sundberg. 1997: Remove EXTRA_DEFINES from Makefile. Breaks some systems. 1998: Move common sprite code from pfield_doline() and pfield_doline_slow() 1999: to new function pfield_sprite(). The same sprite may appear more than 2000: once on the same line, so don't shift out the bits of sprdata[] and 2001: sprdatb[] while displaying it (Turrican I). 2002: In xwin.c and svga.c, barf if LINUX_SVGALIB doesn't match the file 2003: being compiled. 2004: Make all .o files depend on config.h in the Makefile. 2005: No need to exit if sound driver unavailable, but -S given. 2006: Small debugger fix: Missing space in output. 2007: Fix for the sprite logic: Specifically, use a state variable indicating 2008: whether the sprite has been restarted after a VSYNC. Fixes most 2009: Turrican problems. 2010: 960124 Added Denis Sablic's patch for sound run-time option. 2011: Added Ed Hanway's patch for better Makefile, X mouse cursor blanking 2012: and more SGI compilation fixes. 2013: 960123 Include options.h everywhere. 2014: Handle 8 bit GrayScale visuals like PseudoColor. 2015: Remove C++ leftovers from joystick code. 2016: 960122 When using the joystick driver, the button test must come after 2017: handle_events() in vsync_handler(). 2018: 960118 Removed all the remaining C++ comments. Changed all inline keywords to 2019: __inline__. Define __inline__ if not using gcc. 2020: Make proper prototypes for everything. Compile with maximum warnings + 2021: -ansi + -pedantic. 2022: Remove CIA_cycle(), obsolete. 2023: Reimplemented the STOP optimization in newcpu.c. Removed DualCPU 2024: support in CPU emulator. 2025: Real nasty bug in pfield_doline() fixed: sprxpos could be evaluated as 2026: negative, with not-so-amusing results. (Need to rewrite this in 2027: Oberon to get array bounds checking :-) 2028: 960117 Heroic effort: Rewrote the thing in C. This might help fix some 2029: problems with users being unable to compile it. 2030: Fixed a problem in hsync_handler(): Only call flush_line() for lines 2031: in the display window, i.e. when we did a prepare_line() before. 2032: Better code for relative branches: Don't use setpc(getpc()+x) calls, 2033: increment regs.pc_p instead. 2034: 960116 Reimplemented the function to load the Kickstart ROM. Use stdio instead 2035: of fstreams since this apparently does not work on the Mac. Detect 256K 2036: Kickstarts. Detect corrupt ROM images (calculate checksum). 2037: Added Ernesto Corvi's Mac port. Changed it around a bit, so it 2038: probably won't compile. 2039: 960115 Reinstate config.h options for X screen depth, so that DrawPixel() can 2040: be inlined in custom.cc for speed. xlinebuffer is now incremented in 2041: each call to DrawPixel() (for both X and SVGAlib) to get rid of some 2042: address calculations. 2043: 960114 Fixed X generic pixel drawing routine for SHM. 2044: Still trying to fix the harddisk emulation. 2045: uae.device no longer breaks the debugger (can step through uae.device 2046: functions now) 2047: Bugs affecting performance: SPCFLAG_STOP never got reset, and DSKLEN() 2048: would set SPCFLAG_DISK even if DMA was being turned off. 2049: Made slow memory a run-time option. 2050: Defer interrupts by one CPU instruction to give programs a chance to 2051: read INTREQR ("Seeing is Believing" and "Substance" demos) 2052: Added ScrollLock hack for X, too. 2053: 960113 SVGAlib version compiles again. Fixed SVGAlib mouse bug. 2054: Fixed SHM bug: Maximum scanline is 313, not 312. 2055: Sometimes, disk.cc missed a side change and would read the wrong data. 2056: Fixed. Apparently, this was the worst compatibility problem. 2057: Implemented trace mode. 2058: 960112 Changed layout of class amigamemory a little so that gcc can generate 2059: better addressing modes. 2060: Finally wrote functions in gencpu to generate MOVEMs. 2061: 960109 Integrated Ed Hanway's patches for better X support and run-time 2062: configuration of some options. 2063: Got rid of the direct VGA memory access. (Need to do this differently). 2064: Changed the method of drawing lines: custom.cc now tells the graphics 2065: code the line number and whether it needs to be doubleed before drawing 2066: it. 2067: Added Andre Beck's MIT-SHM patch. 2068: Remove warnings for newcpu.cc. 2069: 960108 Fixed exceptions in op_illg(): Need to decrement PC. 2070: 960107 Added an "uae.device" resident module at 0xF00000. This emulates a hard 2071: disk (fixed size 8MB for now). 2072: 960106 Moved some common code from pfield_doline() and pfield_doline_slow() to 2073: a separate function. This fixes a potential HAM bug (two static vars 2074: for the same value). 2075: Sound support for Linux. Works only with graphics off and the CPU 2076: slowed down. 2077: Better SVGAlib keyboard support. 2078: 960105 Added AvailMem(), AllocMem(), AllocAbs() and FreeMem() dummies. 2079: The Hardwired demo times the multiplication instructions and prints 2080: "This demo don't like Axel" if they are too fast. Apparently, Axel has 2081: a 68040. Added a WANT_SLOW_MULTIPLY option to config.h. 2082: Fixed the fast blitter emulation (seems to work now). 2083: 960104 Fixed all the ChangeLog entries from 95 that said 96 (oops??!) 2084: pfield_may_need_update() should check whether bitplane DMA is on. 2085: Added ersatz.cc and ersatz.h. The purpose of these files is to 2086: implement one or two Kickstart functions that are commonly called from 2087: bootblocks. This should help support some games and demos that only use 2088: the Kickstart as an initial track loader. So far, it's only good enough 2089: for one program. 2090: 951223 More intelligent event handling in the CPU emulator. Slightly faster. 2091: 951222 Optimize CPU emulation by inlining cctrue(). Also, the real PC no 2092: longer needs to be incremented each instruction. The real PC value 2093: now has to be fetched by m68k_getpc(). 2094: Added direct screen access for SVGAlib, but it didn't help much. I'll 2095: probably remove it again. 2096: The gencpu executable is 2M smaller if it allocates memory 2097: dynamically. 2098: 951216 custom_bput() enhanced a little. Now remembers the value that was 2099: written in the other half of the register. 2100: Apparently, the USEx bits of BLTCON0 are ignored in line draw mode. 2101: (Silents-Demo) 2102: 2103: 951212 Release 0.3 2104: 951212 Included Alessandro's battclock patch. 2105: Fixed mouse autocalibration for wrong-aspect screens. 2106: 951210 Joystick support for Linux. 2107: Better color matching for 256 color modes. 2108: Rewrote most of the memory management in plain C, mainly to avoid the 2109: various template bugs in some compilers, but also because gcc can't 2110: handle the regparm attribute for virtual functions yet. 2111: 951209 Added Alessandro's patches for automatic mouse calibration. 2112: Tried to optimize the blitter loop a bit. Doesn't work. 2113: 951205 Added Hannu's patches for diskfile write support. 2114: 951201 More portability fixes, especially for weird compilers that workstation 2115: vendors ship. 2116: 951125 More keys for X, some keyboard support for SVGAlib (slightly 2117: dangerous); beginnings of US keyboard support. 2118: 951124 256 color mode support for SVGAlib. FAST! 2119: 951123 Tiny tweak to central loops in playfield code results in much better 2120: assembly. Apparently, GCC does not feel too good about optimizing 2121: reference variables. 2122: 951113 Bug fix in the events code (nextevent must not be changed while events 2123: are being processed). 2124: 951112 The playfield can now be drawn with the right aspect (i.e., every line 2125: twice). Slower, but looks nicer and supports interlaced mode 2126: (flickerfree!). The first 29 lines (blanking interval) are omitted 2127: now to fit everything in 800x600. 2128: Oops, disk drive identification did not work. Fixed, all four drives 2129: appear now. 2130: Oops, CIA_reset() was there all the time but never got called. 2131: Optimized the planar->chunky conversion in pfield_doline() a little. 2132: This really is time critical. 2133: 951111 If colors change on a line, we might still be able to use the full 2134: line update, if the change occurred outside the DIW. Have to be a 2135: little careful, though. 2136: Playfield code now uses real pointers again, but makes sure it can 2137: read enough bytes to complete the current line without segfaulting. 2138: Oops, my "better estimate" (see below) was a mistake. Restored the 2139: original 4 hw cycles per instruction relation. This slows down the 2140: emulator while booting (more screen refreshs), but speeds up many 2141: demos that otherwise spend most of their time waiting for a specific 2142: raster position. 2143: Playfield modulos must be added immediately when DDF stops. (WOC demo) 2144: Portability fixes in disk.cc (null pointers). 2145: Implemented average frame rate calculation ('c' in the debugger). 2146: Debugger fixes. 2147: Sprite fixes (height was wrong, wrong priorities in fast update) 2148: Added an AutoConfig expansion RAM device. The OS seems to recognize 2149: it, but breaks sometime later (seems to be the same bug that kills 2150: the emulator when there's RAM at 0xC00000). 2151: SVGAlib now has mouse support, too. 2152: HAM mode implemented. 2153: 951110 Implemented fast complete line playfield update. Switches back if 2154: necessary. Fixed attached sprites bug. 2155: Copper wait no longer slows down the CPU emulation. (there were 2156: lots of new copper bugs because of this, but I hope I fixed all 2157: of them). 2158: Changed cia?t? from UWORD to ULONG, since there were overflows in 2159: the assertion (because of 65535+1 == 0). 2160: 951108 The DIVS remainder could have the wrong sign. 2161: New HAVE_BROKEN_SOFTWARE define in config.h that makes the emulator 2162: mask out the high byte of all addresses. 2163: Wrote genblitter.cc and replaced the awful code in blitter_blit() 2164: and blitter_line() with calls to the generated function. 2165: 951107 Implemented ?BCD. These don't really work yet. 2166: 2167: 951106 Release 0.2 2168: 951105 Fixed a bug in the new CIA timer code. 2169: Fixed flag settings for some cases of ADDX/SUBX 2170: 951104 Changed the main loop a bit - call all the *cycle() functions only if 2171: it is really necessary. I hope everything still works - at least it is 2172: twice as fast now :-D 2173: Improved mouse emulation - avoid overflows, permit "wraparound". 2174: Added debugger 'g' command. 2175: Removed some useless casts from the CPU emulator. 2176: Added a configuration option to prevent checks for odd addresses. Only 2177: very bad programs need this check. 2178: 951103 The sprite emulation sometimes did not work too well, especially with 2179: dual playfield mode. Hopefully fixed. 2180: 951102 The 10 cycle counter is more like a 5 cycle counter in this 2181: implementation. (Fine, that makes floppy loading even faster :-) 2182: Implemented mouse movement. Totally out of sync with the X pointer, 2183: but at least something. 2184: Found out about the XAutoRepeatOff() function. Real useful. 2185: DualCPU mode works again. 2186: Corrected flag settings for CMPA.W. 2187: Fixed DIV instructions: Don't change dest in case of overflow. 2188: 951031 The PC is now converted to a real pointer. This is safe (much safer 2189: than converting bitplane pointers, since the PC always has to be valid) 2190: and should speed things up a little. 2191: 951029 Some primitive event handling: 2 mouse buttons and 1 joystick button 2192: are emulated, as well as parts of the keyboard (only german mapping). 2193: Fixes: Delay values and sprite widths are always LoRes. Playfield 2 2194: uses colors 9..15. 2195: Implemented a frame rate configuration option that can speed up the 2196: emulation quite a bit. 2197: 951028 A-ha. The 68000 has one strange feature after all. MOVEM.W to Dn sign 2198: extends the value to a longword. 2199: Katakis expects that accessing odd addresses causes exception 3, so 2200: we have to emulate this. *Sigh* 2201: Do at least something with the index pulse bit. It's more or less a 2202: toggle now. 2203: Implemented sprites & dual playfields, both with small glitches. 2204: 951027 When LOF is set, the frame is one line longer. 2205: 951026 Implemented a preliminary diskfile type for special formats. Turrican 2206: boots up correctly (crashes if I want to play a game, though). 2207: Implemented EHB and added a few missing masking operations in the color 2208: handling. 2209: Fixed the absw addressing mode - need to sign extend here as well. 2210: 951025 Fixed another extremely stupid bug, this time in the playfield code. 2211: Each pixel was calculated four times... 2212: Increased the size of the apixels array - this was being overrun. 2213: 951024 Fixed an extremely stupid bug in flag settings for byte and word 2214: operations. 2215: The "sectors until gap" field must be in the range 1..11 instead of 2216: 0..10, or very bad things will happen if it is used to calculate a 2217: blit size. 2218: 951021 Don't use real pointers to fetch bitplane data - too many segfaults. 2219: Delay the copper after executing an instruction, or wait sequences like 2220: FFDF FFFE 0200 FFFE won't work. 2221: Some programs expect that the CPU is completely turned off if the 2222: blitter nasty bit is set. So be it. 2223: The RSI Megademo chokes when disk DMA fetches two syncs. Leave one out. 2224: The LOF bit wasn't set correctly. 2225: 951020 Blitter fixes: Load fill carry from FCI each line; keep the masked 2226: value of bltadat in bltolda 2227: Give the CPU twice as many "cycles" - this still is not even remotely 2228: correct, but a better estimate. 2229: 951017 Added SVGAlib support. Unfortunately, my graphics card isn't fully 2230: supported by the current SVGAlib version. 2231: 951015 More small optimizations to memory.h and custom.cc. 2232: Added code for 256 color screens. The type of screen has to be 2233: selected at compile time. 2234: 951014 Modified the memory management to be (hopefully) a little more 2235: efficient. 2236: Changed gencpu.cc to generate functions and a big function pointer 2237: array instead of the old case labels. The generated C++ files now 2238: compile a lot faster, and the code should be better as well. 2239: 951013 Implemented pseudo POTGOR to keep the RMB from being detected as 2240: pressed all the time. 2241: GenerateDecTab() generated TRAP incorrectly. 2242: Made some more instructions (MOVE.B A0,D0 etc) illegal in gencpu.cc. 2243: Fixed X colors. Fixed data fetching for HiRes screens. 2244: 951011 EXT.WL instructions set the flags. 2245: Implemented second CPU emulator, plus "DualCPU" option. The new CPU 2246: emulator is generated automatically from a file called table68k by 2247: a program called gencpu. 2248: 951002 Removed version information from the file headers. 2249: Removed some sillinesses in custom.cc. 2250: DSKLEN bug fixed (mask out 0xC000). 2251: Playfield code rewritten. Now supports horizontal scrolling. Implemented 2252: some primitive color support. 2253: 950927 Fixed predecrement/postincrement addressing with byte size for the 2254: stack pointer. 2255: 950926 Fixes to the disk code: Terminate disk DMA, flip disk side, read more 2256: than just two sectors during disk DMA, fix checksum calculation. 2257: Fixed copper comparison bugs. 2258: 2259: 950901 Release 0.1 2260: 950826 bugfix in GenerateDecTab(): LEA.W instructions were generated. 2261: 950312 New file disk.cc, for (guess what) disk support. Doesn't work yet. 2262: 950311 Multiplication instructions were generating 16 bit results. 2263: Sign extension was wrong in some places. 2264: Removed bugs in the blitter (one word width: ALWM & AFWM and line mode) 2265: The Kickstart logo looks perfect now. 2266: Playfield routine should check BPLCON0 instead of BLTCON0 2267: 950309 ASR D8,D0 is not a valid instruction. 2268: Bitplane pointers were not incremented. 2269: Copper comparison didn't work. COP2LC and bitplane pointers were written 2270: incorrectly. Fixed. 2271: Something that bears a striking resemblance to the familiar Kickstart 2272: logo now appears in my X window! 2273: 950306 ROR used to set the X flag. Bug fixes in GenerateDecTab. 2274: More bug fixes in several 68000 instructions. 2275: Improved blitter. ?????? KS1.3 doesn't seem to set BLTDMOD on a 2276: line draw. What is this?? 2277: Fixed stupid bugs in playfield code. 2278: 950305 fixed bugs in opcode generation and interrupt handling. Implemented 2279: STOP. Fixed flag settings: Result wasn't masked. Ooops!! 2280: ADDQ #imm,An doesn't set flags. 2281: One-shot timer mode didn't work. 2282: Implemented blitter, doesn't work. 2283: Some primitive and slow playfield support, only to make the things that 2284: hopefully will soon appear visible. 2285: 950304 CIA timers ought to work OK. Copper is emulated. 2286: Emulator loops infinitely when trying to initialize the console.device 2287: 950303 experiments with X, figured out how to open a window and draw pixels. 2288: No graphics emulation yet, though. 2289: 950301 Nearly all instructions work. 2290: Fixed supervisor mode stack. 2291: The memory manager now handles CIA chips. 2292: 950228 Bug fixes in 68000 code, exceptions and more instructions implemented 2293: Memory management extended to handle custom chips as well. 2294: Debugger improved. 2295: Kickstart passes memory & CPU type test, builds up some system 2296: structures. 2297: 950227 MC68000 & little debugger for tracing. It can execute the first couple 2298: of KS1.3 instructions, but doesn't get past the memory test. 2299: 950225 Work begun
