The new insns describe the machine more faithfully, and 713: allow things like clobbering the fp register containing the value, 714: if it is the last use rather than using a specific hard register. 715: (fixuns_truncsfsi2, fixuns_truncdfsi2): New patterns to 716: automatically convert {single,double} precision to unsigned. 717: (anonymous move df/sf patterns): Put the operands to mfc1 in the 718: order the assembler likes them (always put gp reg first, even if 719: moving from gp register to fp register). 720: (wild_insn): Remove bogus insn which is commented out. 721: (jump): Remove TARGET_PIC code for now. 722: 723: * out-mips.c (toplevel, function_epilogue, mips_asm_file_end, 724: mips_output_external): If optimizing for the global pointer, emit 725: all code after processing the entire program, rather than emitting 726: the code at the end of the function. Also, properly sized .extern's 727: are emitted for variables that are not defined in the current 728: module. This is because the MIPS assembler uses single pass 729: semantics, and will emit a 2 instruction sequence for externals it 730: doesn't know anything about, and GCC emits data definitions at the 731: end of the program. You can't just emit a properly sized .extern 732: either, because the assembler will complain if it sees an .extern 733: followed by a definition. The ADDRESSABLE bit in the identifier 734: node for the external name is used to indicate whether a definition 735: for the name exists or not. This replaces code which told the 736: assembler to preprocess the source, and include the same source 737: twice. 738: (sym_lineno): Add a new variable to keep trace of labels emitted 739: after each .loc for Silicon Graphics. 740: (function_prologue, function_epilogue, toplevel): Explicitly use 741: temporary registers for stack frames > 32K, since the Silicon 742: Graphics system doesn't automatically use $at if the value overflows, 743: also save an instruction or two for large stack frames. 744: (init_cumulative_args): Fix to work with the method types G++ 745: produces as well as normal function types. 746: (compare_collect): In debug code, print the mode symbolically. 747: (trace): Take two additional arguments which are passed to fprintf. 748: (override_options): Remove unsupported -mpic code. 749: 750: * tm-decstatn.h (toplevel): Add a GNU copyright. 751: 752: * tm-iris.h (toplevel): Add a GNU copyright. 753: (CPP_SPEC): If -ansi, define __EXTENSIONS__. 754: (SGI_TARGET): Define this for other mips files. 755: (LABEL_AFTER_LOC): New macro to put a label after .loc. 756: (SET_FILE_NUMBER): New macro to force .file/.loc file # to be 1. 757: (ADJUST_STACK_SIZE): Don't deal with variable arguments. 758: 759: * tm-mips.h (*_SPEC): Add #ifdef's so other files can define their 760: own, without #undef. 761: (LINK_SPEC, ASM_SPEC): Pass -EB/-EL to assembler, linker so cross 762: compilers can be made from little endian mips to big endian mips and 763: vica versa. Generate an error message if the wrong flag is used. 764: Do not pass -EB/-EL to Silicon Graphics assembler/linker. 765: (CPP_SPEC, MACHINE_NAME): Add Silicon Graphics defaults. 766: (MIPS_TEMP?_REGNUM): New macros for temporary registers used in the 767: prologue and epilogue if the stack frame is > 32K. 768: (ASM_OUTPUT_LABEL): If optimizing the global pointer, set the 769: addressable bit in the indentifier node, so that mips_asm_file_end 770: and mips_output_external can figure out if a particular identifier 771: really is external to the compiliation unit. 772: (ASM_OUTPUT_COMMON): Same change as ASM_OUTPUT_LABEL. 773: (ASM_OUTPUT_LOCAL): Same change as ASM_OUTPUT_LABEL. 774: (MACHINE_TYPE): Key off of OSF_OS and SGI_TARGET macros. 775: (TARGET_DEFAULT): For OSF/1 make -mgas and -G 0 default. 776: (STACK_POINTER_OFFSET): Define as 0. 777: (external variables): Declare flag_omit_frame_pointer, 778: sdb_label_count, mips_section_threshold, and sym_lineno. 779: (STACK_ARGS_ADJUST): Protect with an #ifndef. 780: (FUNCTION_PROFILER): Talk to the MIPS profiling routines the same 781: way the MIPS compiler does. 782: (INDIRECTABLE_ADDRESS_P): Allow disp+reg in addition to reg+disp. 783: (ASM_FILE_START): If optimizing for the global pointer, create a 784: temporay stream to hold text until program ends. Put gcc_compiled. 785: in the data section. 786: (ASM_DECLARE_FUNCTION_NAME): Switch file streams used to the text 787: stream if optimizing for the global pointer. 788: (ASM_FILE_END): New macro to invoke mips_asm_file_end function. 789: (ASM_OUTPUT_SOURCE_LINE): Invoke macro LABEL_AFTER_LOC after .loc, 790: so that Silicon Graphics can put out a label after each .loc. 791: (ASM_OUTPUT_SOURCE_FILENAME): Invoke macro SET_FILE_NUMBER to set 792: the file number, so Silicon Graphics can hardwire this to 1. 793: (LABEL_AFTER_LOC, SET_FILE_NUMBER): Provide defaults if not Silicon 794: Graphics. 795: (ASM_OUTPUT_ASCII): Assign parameter to local variable, and remove 796: special \a, \v support. 797: (ASM_OUTPUT_IDENT): Dump #ident directives into .data. 798: 799: Mon Nov 26 16:50:57 1990 Richard Stallman (rms at mole.ai.mit.edu) 800: 801: * cccp.c (main): Handle -w. 802: (warning): Do nothing if -w. 803: * gcc.c (compilers): Pass -w to cpp. 804: 805: Sun Nov 25 16:37:10 1990 Richard Stallman (rms at mole.ai.mit.edu) 806: 807: * expr.c (emit_push_insn): Don't pad at all if space already allocated 808: and padding is upward. 809: 810: * gcc.c (do_spec_1): Handle %W{...}. 811: (compilers): Use %W{...} when passing -o option. 812: 813: Sat Nov 24 16:50:11 1990 Richard Stallman (rms at mole.ai.mit.edu) 814: 815: * va-mips.h (va_list): Don't typedef if _VA_LIST_ is defined. 816: 817: Wed Nov 21 15:57:48 1990 Richard Stallman (rms at mole.ai.mit.edu) 818: 819: * expr.c (expand_expr, expand_assignment): 820: Check for TREE_THIS_VOLATILE in ARRAY_REF. 821: expand_assignment failed to handle volstruct at all. 822: 823: Tue Nov 20 17:47:22 1990 Richard Stallman (rms at mole.ai.mit.edu) 824: 825: * out-sparc.c (output_fp_move_double): Handle reg+reg address 826: when moving each word separately. 827: 828: * ns32k.md (addsi3): Don't use `addr' for very large displacements. 829: 830: * recog.c (address_operand): Don't allow volatile mem as indirect. 831: 832: Mon Nov 19 14:55:44 1990 Richard Stallman (rms at mole.ai.mit.edu) 833: 834: * out-sparc.c (output_fp_move_double): Don't assume arrays are aligned. 835: 836: Sun Nov 18 19:21:10 1990 Richard Stallman (rms at mole.ai.mit.edu) 837: 838: * expr.c (emit_push_insn): set extra to 0 once the padding is done, 839: to avoid padding twice. 840: 841: Thu Nov 15 21:56:07 1990 Richard Stallman (rms at mole.ai.mit.edu) 842: 843: * math-68881.h (HUGE_VAL): Add extra braces on Sun. 844: 845: Wed Nov 14 14:30:29 1990 Richard Stallman (rms at mole.ai.mit.edu) 846: 847: * c-decl.c (grokdeclarator): Don't ignore prototype if -traditional. 848: 849: Tue Nov 13 18:16:47 1990 Richard Stallman (rms at mole.ai.mit.edu) 850: 851: * out-i860.c (output_block_move): Move .Lm%3 down one insn. 852: 853: Wed Nov 7 00:01:18 1990 Richard Stallman (rms at mole.ai.mit.edu) 854: 855: * c-parse.y (component_decl_list): Allow missing semi at end. 856: 857: Tue Nov 6 20:49:57 1990 Richard Stallman (rms at mole.ai.mit.edu) 858: 859: * expr.c (expand_builtin): For ffs, use mode of operand. 860: 861: * xm-iris.h (alloca): Don't define it. 862: * tm-iris.h (CPP_SPEC): Define variant symbols starting with _. 863: Define __EXTENSIONS__. 864: 865: * config.gcc (editing .gdbinit): Search current dir, not just srcdir. 866: 867: Sun Nov 4 12:55:03 1990 Richard Stallman (rms at mole.ai.mit.edu) 868: 869: * i386.md (extend*): Take out last change. 870: Unix assembler rejects movsx... 871: 872: * expr.c (expand_expr): Special case for ignored volatile 873: failed to return. 874: 875: Fri Nov 2 15:30:48 1990 Richard Stallman (rms at mole.ai.mit.edu) 876: 877: * va-i860.h (_VA_LIST): New macro avoids duplicate typedefs. 878: 879: * gnulib2.c (__builtin_saveregs): Add version for i860. 880: 881: * out-i860.c (output_block_move): Rearrange the copy loop. 882: Now uses two labels and a more complicated lead-in. 883: 884: Thu Nov 1 18:15:11 1990 Richard Stallman (rms at mole.ai.mit.edu) 885: 886: * config.gcc (sun3, etc.): Assume os4 as default for Sun 3 and Sun 4. 887: 888: * math-68881.h (HUGE_VAL): Alternate definition for Suns. 889: 890: * tm-i386v.h (STARTFILE_SPEC, LIB_SPEC): Handle -posix. 891: (CPP_SPEC): New macro. 892: (LIB_SPEC): Handle -shlib. 893: 894: Wed Oct 31 22:12:33 1990 Richard Stallman (rms at mole.ai.mit.edu) 895: 896: * config.gcc (ultrix): New alternative. 897: 898: * i386.md (extend*): Change opcode to movsx.
