Also 509: made sure that the symbol indicies were correct even in the 510: presence of indirection information. 511: 512: * ld.c (write_rel): When specifying symbol numbers, make sure to 513: leave room for the extra undefined ref that will be written for 514: the sake of N_INDR entries. 515: 516: * ld.c (write_syms): Fixed typo; a duplicate of the N_INDR entry 517: was being written instead of the undefined ref required. 518: 519: Tue Jan 17 16:23:56 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu) 520: 521: * strip.c (rename): Arranged to ignore return code from "unlink"; 522: file may not be there. 523: 524: Thu Jan 12 15:24:23 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu) 525: 526: * Makefile: Modified "dist" target so as to get hp-* 527: subdirectories. 528: 529: * strip.c (rename): Added function to mimic BSD system call for 530: system V. 531: 532: Tue Jan 10 19:44:33 1989 Pace Willison (pace at prep.ai.mit.edu) 533: 534: * Makefile: put -Dnounderscore back for COFF_ENCAPSULATE. 535: 536: Tue Jan 10 17:58:50 1989 Randall Smith (randy at cream-of-wheat.ai.mit.edu) 537: 538: * ld.c (linear_library, symdef_library, list_file_locals, 539: write_file_syms): Took care to make sure that when the buffer 540: pointed to by entry->strings became invalid, entry->strings was 541: set to zero (either on a free or a function return if space had 542: been allocated through alloca). 543: 544: * ld.c (getpagesize): Deleted define in hpux dependent section; 545: taken care of when compiling on hpux because of define of USG in 546: Makefile. 547: 548: Mon Jan 9 22:49:42 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu) 549: 550: * strip.c (strip_file): Effectively defer certain signals 551: while rewriting the file. 552: 553: Mon Jan 9 09:45:41 1989 Pace Willisson (pace at prep.ai.mit.edu) 554: 555: * These changes improve support for COFF_ENCAPSULATE, and 556: for the future development of the GNU exec header. The 557: main change is to rename the exec header field a_magic 558: so that it can contain additional information. Now, the 559: magic number must be accessed with N_MAGIC(exec), and set 560: with N_SET_MAGIC(exec,val). Programs that only need to use 561: N_BADMAG will not have to change. Also COFF_ENCAPSULATE will 562: no longer use "nounderscore", so that it will be more like 563: normal bsd systems. This means gcc must be updated before using 564: these new tools. (It is safe to put -Dnounderscore back in 565: if you want to use an old gcc for a while.) 566: 567: * README-ENCAP: new documentation for how to set up to use 568: COFF_ENCAPSULATE. 569: 570: * Makefile: Add target for gnulib. 571: Don't define 'nounderscore' (must tell gcc about that too.) 572: 573: * ar.c: Don't automatically define COFF_ENCAPSULATE. 574: 575: * nm.c: No need to initialize the header before reading it. 576: 577: * size.c: Include, sys/types.h, and sys/fcntl.h if USG 578: * strip.c: Likewise--types.h before file.h. 579: 580: * ld.c, objdump.c, robotussin.c: 581: Changed to use new exec macros for a_magic. 582: 583: * libconvert: now takes arguments 584: 585: * robotussin.c: don't automatically define nounderscore - leave 586: that to the makefile, if desired 587: 588: Fri Jan 6 13:06:37 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu) 589: 590: * ld.c (digest_symbols, write_text, write_data): Changed N_SETV 591: from being in the text area to being in the data area. 592: * nm.c, a.out.gnu.h: Changed comments to conform with above. 593: 594: * ld.c (do_file_warnings): Added loop to go through each external 595: nlist entry and check for multiple definitions, as well as 596: catching any references which weren't caught by the relocation 597: pass. 598: 599: * ld.c (address_to_line): Changed so that it will work (albeit 600: slowly) with an address less than the current address. 601: (do_file_warnings, do_relocation_warnings): Broke out scan through 602: relocation entries into a separate function. Added creation of a 603: bitvector with each bit refereing to an nlist entry so that 604: do_relocation_warnings could mark which symbol entries it had 605: output for undefined references. 606: 607: Thu Jan 5 20:36:44 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu) 608: 609: * ld.c: Cosmetic changes: Moved helper functions for 610: do_file_warnings to before it and modified comments to 611: next_debug_symbol and address_to_line. 612: 613: Wed Jan 4 15:37:52 1989 Randall Smith (randy at gluteus.ai.mit.edu) 614: 615: * ld.c: Added #define getpagesize() EXEC_PAGESIZE for hpux. 616: 617: * ld.c (do_warnings): Will now print out all undefined external 618: symbols which were not referenced from the text or data sections 619: separately. 620: (do_file_warnings): Decreases undefined_global_sym_count for each 621: symbol printed. 622: 623: Tue Jan 3 23:43:41 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu) 624: 625: * Makefile (nm): Link with $(LIBS). 626: 627: * ld.c (getpagesize): HPUX definition deleted; not needed. 628: 629: Mon Jan 2 23:04:35 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu) 630: 631: * ld.c (digest_symbols): Modified the creation of set vectors 632: to include a zero word after the end of the vector. 633: (write_text): Made the same modification of the set vector section 634: size. 635: 636: Sun Jan 1 12:01:22 1989 Randall Smith (randy at apple-gunkies.ai.mit.edu) 637: 638: * ld.c: Fixed typo in description of relocation values, and 639: changed note on RELOC_ADD_EXTRA to force is to be an lvalue if 640: it's defined. 641: (coptxtrel): If a specific relocation entry has just changed from 642: external to internal, and we aren't supposed to add in memory on 643: the new relocation value, make sure that the value of the symbol 644: get's added to the ADD_EXTRA in the relocation value. Otherwise, 645: all the work we do in a partial linking will be wasted (will be in 646: memory, but will be ignored on the next pass of the linker). 647: 648: Sat Dec 31 13:13:01 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu) 649: 650: * ld.c: Removed "|| TARGET == SUN2" from line 210; I believe that 651: TARGET and SUN2 were both showing up defined as 0 on the sparc, 652: which resulted in a redefine of the INITIALIZE_HEADER macro, back 653: to sun2 style. 654: 1.1 root 655: Thu Dec 29 01:48:03 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu) 656: 657: * ld.c, ar.c: Don't define COFF_ENCAPSULATE automatically. 658: The recommended Makefile change defines it. 659: 660: * ld.c (alloca): If compiling with GCC, use __builtin_alloca. 661: 662: * robotussin.c: New reformatted version with all variables renamed. 663: 664: * ranlib.c: New file, just runs `ar rs' on each specified file. 665: * Makefile: Special hack to tell ranlib where to find GNU ar. 666: (LIBS): Recommend -lPW on USG; ld needs it for alloca (if not GCC). 667: 668: Sat Dec 24 13:59:09 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu) 669: 670: * ld.c (error): Start with name of program running. 671: (main): Set `progname' to that name. 672: (digest_symbols): Fix punctuation and spelling in calls to `error'. 673: 674: Tue Dec 20 21:49:46 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu) 675: 676: * robotussin.c (INPUT_MAGIC): New macro, has the magic number 677: to expect in input files. 678: (nounderscore): New macro; as in ld, define it to inhibit 679: adding underscore to symbols. 680: 681: * Makefile: Don't compile objdump on BSD; N_DATADDR causes trouble. 682: 683: Tue Dec 20 14:57:38 1988 Pace Willisson (pace at prep.at.mit.edu) 684: 685: * objdump.c: New program like the system 5 'dump' program. 686: Documentation will follow... 687: 688: * Makefile: Set up CFLAGS for USG systems. Added target 689: libc.a to do robotussin conversion. Added objdump. 690: 691: * libconvert: Wrote shell script to do robotussin conversion. 692: 693: * ar.c, ld.c: Don't define COFF_ENCAPSULATE if it is already defined. 694: 695: * ld.c: If i386, set a_machtype to M_386. Use a_flags instead 696: of a_encap. Don't compute coff header if it isn't going to 697: get written out. 698: 699: * robotussin.c: Define COFF_ENCAPSULATE. Include a.out.encap.h 700: instead of a.out.h. Check magic number of input 701: file. Skip over optional header, if present. Don't ignore 702: symbols with aux entries (they could be function definitions), 703: instead, ignore symbols beginning with '.' (.text, etc). 704: Don't prepend underscore to externals, since gcc doesn't do 705: it now. Don't run past the end of symbols that are exactly 706: eight characters long. Always write the string table size, 707: even if it is empty. Change relocation types handled from 708: R_PCRBYTE, etc, to R_DIR32 and R_PCRLONG (these are the 709: only two emitted by the system 5 assembler.) 710: 711: * size.c: Include <sys/types.h> so including sys/file.h will 712: not get an error on USG systems. Include fcntl.h on usg systems. 713: 714: * strip.c: Move inclusion of file.h to after types.h. Include 715: fcntl.h. Add defintion of rename. 716: 717: Fri Dec 16 13:55:11 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu) 718: 719: * size.c: Delete all ROBOTUSSIN conditionals and contents. 720: Change SYSV conditionals to USG. 721: COFF_ENCAPSULATE conditionals for headers. 722: (do_one_file, read_header): Skip encapsulation headers if any. 723: 724: * strip.c: Delete all ROBOTUSSIN conditionals and contents. 725: Change SYSV conditionals to USG. 726: COFF_ENCAPSULATE conditionals for headers. 727: (file_open, read_header): Skip encapsulation headers if any. 728: 729: * strip.c: Change most fatal errors to nonfatal. 730: (file_open, read_header, read_{file,entry}_symbols): 731: Now return 0 for success, -1 for failure. 732: Failure means do no more for the current file. 733: (modify_relocation): Now just warn if strip a symbol needed 734: for relocation, and warn only once per file. 735: (error_with_file): New function, replaces most fatal_with_file. 736: Print filename first, as in most programs. 737: (fatal_with_file): Deleted. 738: (rewrite_file_symbols): Use perror_file when system call fails. 739: 740: Tue Dec 13 17:16:39 1988 Jay Fenlason (hack at apple-gunkies.ai.mit.edu) 741: 742: * ar.c: Changed pad character after odd-length archive member 743: from \0 to \n so archives can be cmp'd with the output from /bin/ar 744: Added fix for when ranlib is using ar to insert an __.SYMDEF member 745: 746: Tue Dec 13 09:09:27 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu) 747: 748: * ar.c: conditional #includes for USG. 749: * COFF_ENCAPSULATE conditionals for headers. 750: (extract_member): Don't do fchmod if USG. 751: Alternate USG code to set modtimes of extracted members. 752: (write_archive): Don't do fsync if USG. 753: (make_new_symdefs): Skip encapsulation headers if any. 754: [USG] (bcopy, bzero, bcmp): New fns. 755: 756: * nm.c: Delete all ROBOTUSSIN conditionals and contents. 757: Include types.h. 758: Change SYSV conditionals to USG. 759: * COFF_ENCAPSULATE conditionals for headers. 760: (do_one_file): Skip encapsulation headers if any. 761: (read_header): Likewise. 762: 763: * ld.c: Delete all ROBOTUSSIN conditionals and contents. 764: Change SYSV conditionals to USG. 765: Change HEADER_TYPE back to `struct exec'. 766: (L_SET): Define it if headers don't. 767: * COFF_ENCAPSULATE conditionals for headers. 768: (main): Update text_size differently if encapsulating. 769: (write_header): Write the encapsulation headers if nec. 770: Don't end with padding if encapsulation being done. 771: [USG] (bzero, bcopy, getpagesize): New fns. 772: 773: Tue Dec 6 13:26:56 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu) 774: 775: * ld.c (do_file_warnings): Ignored text relocation entries that 776: went through local symbols; any problems with lack of definitions 777: etc. with them would have been caught by the compiler. 778: 779: Mon Dec 5 16:13:22 1988 Jay Fenlason (hack at sugar-bombs.ai.mit.edu) 780: 781: * ar.c (make_new_symdefs): On error, close the input files. 782: 783: Thu Nov 10 18:15:07 1988 Randall Smith (randy at apple-gunkies.ai.mit.edu) 784: 785: * ld.c: Put declaration of alloca inside an #ifdef so that it 786: wouldn't mess up on the sparc. 787: 788: * ld.c: Added #define CORE_ADDR for include of symseg.h from gdb 789: and took out TARGET == SUN2 for sun2 INITIALIZE_HEADER. 790: 791: Wed Nov 2 18:43:09 1988 Randall Smith (randy at gluteus.ai.mit.edu) 792: 793: * ld.c: Merged in isi68k port. This included a kludge for symbols 794: starting with _$ (#ifdef DOLLAR_KLUDGE) and addition of the 795: STANDARD_SEARCH_DIRS macro to override the default if it's 796: defined. 797: 798: * ld.c: Added code for the N_WARNING symbol type. If a reference 799: is found to a symbol in an input .o file which contains an 800: N_WARNING symbol, a warning message (the name of the N_WARNING 801: symbol) is printed. This name is treated as a printf format 802: string; the name of the symbol referenced (which caused the 803: warning) is supplied as a single argument to the print which 804: interpets this string. 805: 806: Tue Nov 1 16:57:00 1988 Randall Smith (randy at gluteus.ai.mit.edu) 807: 808: * ld.c: Added code for Sun 2. 809: 810: * ld.c: Modified access to the relocation information to be *much* 811: more general; added in sparc support. This change is a minor 812: performance hit; the perform_relocation routine uses about 0.1 813: seconds more time on linking gdb than did the original ld. 814: (perform_relocation is about 5% of the total time the loader 815: spends). The price of generality. 816: 817: Thu Aug 4 13:20:50 1988 Randy Smith (randy at rice-chex.ai.mit.edu) 818: 819: * Modified ld.c to print only the first 10 unresolved references 820: for each symbol, followed by a message indicating that there are 821: more unresolved references that have not been printed (if indeed 822: there are). Made default behaivior upon errors *not* writing any 823: output file at all. Also added the -noinhibit-exec flag to force 824: writing of an executable when that was desirable. 825: 826: Tue Aug 2 12:04:01 1988 Randy Smith (randy at rice-chex.ai.mit.edu) 827: 828: * Modified ld.c to give line numbers wherever possible on 829: unreferenced symbols. Added a new symbol (N_DSLNE) to allow for 830: the same mapping of data location to line number as is done for 831: text segments by N_SLINE. Added code to sort the relocation 832: entries when it is necessary to output these line numbers. The 833: assumption was made that both N_SLINE and N_DSLNE symbols would 834: always be in order by address. 835: 836: Wed Jul 27 15:13:08 1988 Randy Smith (randy at rice-chex.ai.mit.edu) 837: 838: * Modified ld.c to include a facility for equivalencing two 839: symbols (translating one to another). Modified lib/a.out.h to 840: include a definition of this new symbol. Modified nm.c to 841: recognize this symbol and all of the set element and vector 842: symbols I had added before. 843: 844: Thu Jul 21 17:06:10 1988 Randy Smith (randy at rice-chex.ai.mit.edu) 845: 846: * Modified ld.c to printout source file and line numbers for 847: unresolved references whenever possible (ie. whenever the input 848: file has debugger symbols and the reference is from the text area). 849: 850: Wed Jul 13 17:21:33 1988 Randy Smith (randy at frosted-flakes.ai.mit.edu) 851: 852: * Modified ld.c and a.out.h to handle new types of symbols; the 853: loader can now create "sets" of symbols from entries in its input 854: files. See a.out.h for more info. Also fixed a bug in ld in 855: which references to common areas that we not defined in one pass 856: of the loader caused errors on the next. 857: 858: Sat Jul 2 00:05:44 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu) 859: 860: * ld.c (symdef_library): Error check was off by one. 861: 862: Mon May 9 12:53:08 1988 Chris Hanson (cph at kleph) 863: 864: * ar.c (replace_members): After updating map, write out 865: `change_map->next' rather than `map', since the latter may be 866: null. 1.1.1.3 ! root 867: ! 868: Local Variables: ! 869: mode: indented-text ! 870: left-margin: 8 ! 871: version-control: never ! 872: End:
