495 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
496 *-*-solaris case, and move to before *-sysv* case that wants to
497 set obj_format to coff.

521 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
523 * Extensive changes to permit symbols to contain any expression
524 type and to delay the computation of the expression until the
525 value is actually needed. This permits setting symbols to values
526 calculated based on object code size. Expressions were changed to
527 no longer be in a section, to stop the overloading of segment and
528 expression type that previously occurred.
530 * as.c (big_section, pass1_section, diff_section, absent_section):

616 (previous_section, previous_subsection): New vars.
617 (obj_elf_section): Save current place in case DWARF code wants us
618 to pop back to it. Handle unquoted section name as well as quoted
619 section name. Don't crash on invalid strings.
620 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
623 * config/obj-elf.h: Don't include struc-symbol.h.

657 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
659 * read.c (float_cons): Simplified parsing logic. If
660 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
662 * symbols.c (colon): Rather than a special case for TC_HPPA,

679 (append_insn): Only insert necessary NOP instructions.
680 (macro): Call mips_emit_delays before setting mips_noreorder.
681 Increment and decrement mips_noreorder rather than using
682 save_reorder_condition. Don't bother to use noreorder in

1973 prototypes for all static functions. Moved existing minimal
1974 debugging format support info #ifndef OBJ_ECOFF blocks.

2347 (operand): Treat zero byte as end-of-operand.
2349 * configure.in (per-target): Look for with_bfd_assembler option.
2350 For now, only accept "no", until the merge is done.
2352 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
2353 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
2354 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
2355 * read.c: Finish conversion to S_* macros in the VMS only
2356 parts of the program. Add "const" modifier to hex_value.
2357 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
2359 * expr.c: Add "const" modifier to hex_value.
2360 * symbols.c: Finish conversion to S_* macros in the VMS only
2361 parts of the program. Add "const" modifier to
2362 md_[long,short]_jump_size. Remove declaration of const_flag
2363 (which will be declared in obj-vms.h).
2364 * write.c: Add "const" modifier to md_[long,short]_jump_size.
2365 Fix arguments to VMS_write_object_file.
2366 * config-gas.com: New file. Script for VMS systems to set up the
2367 configuration to build gas for VMS, and create config.status.

2383 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2384 as symbols as well in the object file. Look for external functions

2434 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2436 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2437 declare with format attribute for -Wformat checking.
2439 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2441 * app.c, config/tc-*.c: Don't include read.h, since it is already
2444 * These are based on patches from Minh Tran-le
2445 <mtranle@paris.intellicorp.com>.
2446 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2447 obj_format coffbfd and gas_target i386coff for target.
2448 (i[34]86-*-isc*): New host (uses sysv).
2449 * config/i386aix.mt: Removed (no longer used).
2450 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2452 (LDFLAGS): Added, defined as -shlib.
2453 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2454 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2455 (DOT_LABEL_PREFIX): Define.
2456 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2457 name rather than L0\001.
2458 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
2460 * symbols.c, symbols.h (local_bss_counter): Removed.
2461 * write.c (write_object_file): bss no longer uses
2462 local_bss_counter. Pass correct data and bss size to
2463 VMS_write_object_file.

2469 (size_section): Restored sanity check.
2470 (do_relocs_for): Base section address on s_paddr rather than
2471 computing it. Adjust a29k R_IHIHALF special case to account for
2472 section paddr (used to require paddr to be zero). If there are no
2473 reclos, set s_relptr to 0. Set relocation size in object_headers.
2474 (fill_section): Always set s_vaddr here, removing
2475 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2476 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2477 Set STYP_INFO for .comment.

2482 (do_linenos_for): Set lineno size in object_headers.
2483 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2484 set s_vaddr here. If string_byte_count remains 4, set it back to
2485 0, and only write strings out if there are some. Call
2486 fill_section before do_relocs_for and do_linenos_for.
2487 (obj_coff_section): Handle optional quoted second argument giving
2488 section characteristics.
2489 (obj_coff_bss): Added to handle .bss.
2490 (obj_coff_ident): Added to handle .ident (puts string in .comment
2492 (obj_coff_lcomm): Put common symbols in .bss, not .data.
2493 (fixup_mdeps): Change to segment. Call frag_wane after
2495 (fixup_segment): Explicitly check S_IS_COMMON before making 386
2496 adjustment (already happened only for common symbols, but this is
2498 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

2510 (do_scrub_next_char): For \", return " not '.
2511 (symbol_chars): Now const.
2513 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2514 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2516 * config/obj-coff.h: Don't use #elif.
2518 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2519 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2546 using ZERO_BASED_SEGMENTS.
2547 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2548 never set segment address for SEG_E2 (.bss) and don't write out
2549 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2550 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2551 definitions, and don't merge tags with non-tags. Check for .bf
2552 rather than just checking whether the second character is b and
2553 the third character is f.
2554 (obj_coff_val): gcc can generate values which we don't handle
2555 correctly; discard information for now, since it only affects the
2556 debugging information.

2558 (yank_symbols): Don't merge labels.
2559 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2704 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
2705 could be doing emulation.
2707 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2710 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
2713 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
2715 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

2739 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
2741 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2742 constant will not fit in an immediate field.
2743 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
2745 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

2778 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
2780 * Support for i386-sysv.
2781 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

2785 (fill_section): Don't set STYP_NOLOAD for .bss section.
2786 (fixup_segment): 386 uses strange common symbol format.

2805 * tc-m68k.c (get_num): make it work for all segments, not just the
2808 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
2810 * configure.in: recognize i386-*-bsd emulation.

2819 * tc-z8k.c: lots of bug fixes
2821 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2823 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2824 #elif, since it is not supported by old compilers.
2825 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2826 couple of expressions in tc-m68k.c.
2828 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2830 * read.c (cons): If NO_RELOC is defined, use it.
2832 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2834 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2836 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2837 local labels to start with a .) and set REGISTER_PREFIX to %.
2838 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2840 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
2842 * messages.c: Comment changes.
2844 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
2846 * as.h: Test if __STDC__ is defined only, don't test its value.
2847 * messages.c: If __STDC__ is not defined, define NO_STDARG.
2849 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
2851 * listing.c (debugging_pseudo): Add stabs and stabn as things to
2854 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2856 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2857 sections starting from zero, rather than making them consecutive.
2858 This makes subsequent reloc calculations easier, esp if the object
2859 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2860 allocate lcomm in .data rather than in .bss. It seems that some
2861 tools can't cope with a non-zero sized bss before linkage.
2863 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2865 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2866 throughout. That enum no longer means what we thought it meant.
2868 * tc-m68k.c (md_assemble, md_parse_option): Handle new
2869 "-mno-688[58]1" options.
2871 * tc-m68k.c: Added CPU32 support.
2873 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2875 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
2877 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
2879 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
2880 Change LIBDEPS dependence to LIBS.
2882 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
2884 * Makefile.in (install): if $(tooldir) exists, install as in
2887 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2889 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2890 .word is < -32768 or > 32767. The -J flag causes the error to be
2891 ignored. This is to catch over-sized switches generated by gcc on
2892 systems which don't support the broken .word hack.
2893 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2894 write.c (fixup_segment): check for signed .word overflow if
2895 WARN_SIGNED_OVERFLOW_WORD.

3382 machine is a SPARC or a 29K.
3383 * config/obj-aout.c: added s_sect pseudo op
3384 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3385 fill in the timestamp.

3394 * Makefile.in: put header files before C source for TAGS; remove
3395 references to non-existent syscalls.h.
3397 * read.c, write.c subsegs.c: back out the .bss changes.
3399 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3401 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

3407 * symbols.c (local_label_name): symbols now start with ^A.
3409 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3410 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3411 generate these sections. .align: will use NOP_OPCODE or 0
3412 for padding. This is just for being nice to the
3415 * expr.c (operand): changed to generate local label "\001L0"
3416 starting with a ^A so that it is recognized as a local label.
3418 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3420 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3421 i/o opcodes - inb, inw, outb and outw. string manipulation with
3422 att syntax - scmp, slod, smov, ssca, ssto.
3424 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3425 to just after .file .
3427 In obj_crawl_symbol_chain() where it tries to put the external
3428 symbols apart, with the condition:
3429 (!S_IS_DEFINED(symbolP) &&
3430 !S_IS_DEBUG(symbolP) &&
3431 !SF_GET_STATICS(symbolP))
3432 it was moving too many symbols out. So I switch it back to the
3434 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3436 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3437 so that we don't use the F_RELFLG which make the linker complain
3438 that somebody has stripped the relocation info.
3440 Also, the AIX ld program require that the relocation table
3441 is sorted by r_vaddr like the standard ATT assembler does.
3443 [he also changed the sizeof(struct ...)'s into the coff
3444 style FOOSZ macros. I'm not sure this is right, but I can't
3445 remember why. xoxorich.]

3449 * Makefile.in, configure.in, doc: use the doc. Build it, install
3452 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3454 * read.c: white space and comments only.
3456 * configure.in: use the new atof-ns32.c for ns32k.
3458 * write.c: comment change only.
3460 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3461 aren't yet integrated.
3463 * tc-i860.[hc]: blew off the dust. Something must still be done
3464 about conflicting relocation types.
3466 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3469 * tc-i960.c, tc-sparc.c: white space and comments only.
3471 * tc-a29k.h: delete duplicate macro definition.
3473 * new file atof-ns32k.c copied from hack's last unreleased gas.
3475 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3477 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3480 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3481 ChangeLog's prior to this are sketchy at best. I have logs.
3482 They just aren't ChangeLogs.
