498 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
500 * Extensive changes to permit symbols to contain any expression
501 type and to delay the computation of the expression until the
502 value is actually needed. This permits setting symbols to values
503 calculated based on object code size. Expressions were changed to
504 no longer be in a section, to stop the overloading of segment and
505 expression type that previously occurred.

596 section name. Don't crash on invalid strings.
597 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
600 * config/obj-elf.h: Don't include struc-symbol.h.

634 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
636 * read.c (float_cons): Simplified parsing logic. If

657 (macro): Call mips_emit_delays before setting mips_noreorder.
658 Increment and decrement mips_noreorder rather than using

1875 * config/tc-mips.c (macro): Use $AT if target register is zero in
1876 load instruction, which it can be for a floating point load.

1950 prototypes for all static functions. Moved existing minimal
1951 debugging format support info #ifndef OBJ_ECOFF blocks.

2324 (operand): Treat zero byte as end-of-operand.
2326 * configure.in (per-target): Look for with_bfd_assembler option.
2327 For now, only accept "no", until the merge is done.
2329 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
2330 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

2336 * expr.c: Add "const" modifier to hex_value.
2337 * symbols.c: Finish conversion to S_* macros in the VMS only
2338 parts of the program. Add "const" modifier to
2339 md_[long,short]_jump_size. Remove declaration of const_flag
2340 (which will be declared in obj-vms.h).
2341 * write.c: Add "const" modifier to md_[long,short]_jump_size.
2342 Fix arguments to VMS_write_object_file.
2343 * config-gas.com: New file. Script for VMS systems to set up the

2403 mapping to segT enum values.
2404 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
2405 if these are used or defined, if BFD_ASSEMBLER.
2406 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
2407 subseg_new split into two functions.
2408 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2410 * as.h (volatile): Don't define if already defined.
2411 (had_errors, had_warnings): Provide prototypes for ANSI C even if

2414 declare with format attribute for -Wformat checking.
2416 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2418 * app.c, config/tc-*.c: Don't include read.h, since it is already
2421 * These are based on patches from Minh Tran-le
2422 <mtranle@paris.intellicorp.com>.
2423 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2424 obj_format coffbfd and gas_target i386coff for target.
2425 (i[34]86-*-isc*): New host (uses sysv).
2426 * config/i386aix.mt: Removed (no longer used).
2427 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2429 (LDFLAGS): Added, defined as -shlib.
2430 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2431 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2432 (DOT_LABEL_PREFIX): Define.
2433 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2434 name rather than L0\001.
2435 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
2437 * symbols.c, symbols.h (local_bss_counter): Removed.
2438 * write.c (write_object_file): bss no longer uses
2439 local_bss_counter. Pass correct data and bss size to
2440 VMS_write_object_file.

2446 (size_section): Restored sanity check.
2447 (do_relocs_for): Base section address on s_paddr rather than
2448 computing it. Adjust a29k R_IHIHALF special case to account for
2449 section paddr (used to require paddr to be zero). If there are no
2450 reclos, set s_relptr to 0. Set relocation size in object_headers.
2451 (fill_section): Always set s_vaddr here, removing
2452 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2453 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2454 Set STYP_INFO for .comment.
2455 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
2456 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

2458 H_{SET,GET}_* macros.
2459 (do_linenos_for): Set lineno size in object_headers.
2460 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2461 set s_vaddr here. If string_byte_count remains 4, set it back to
2462 0, and only write strings out if there are some. Call
2463 fill_section before do_relocs_for and do_linenos_for.
2464 (obj_coff_section): Handle optional quoted second argument giving
2465 section characteristics.
2466 (obj_coff_bss): Added to handle .bss.
2467 (obj_coff_ident): Added to handle .ident (puts string in .comment
2469 (obj_coff_lcomm): Put common symbols in .bss, not .data.
2470 (fixup_mdeps): Change to segment. Call frag_wane after
2472 (fixup_segment): Explicitly check S_IS_COMMON before making 386
2473 adjustment (already happened only for common symbols, but this is
2475 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
2476 * config/tc-i386.c (s_bss): Don't use if I386COFF.

2486 * app.c (app_push): Use memcpy, not bcopy.
2487 (do_scrub_next_char): For \", return " not '.
2488 (symbol_chars): Now const.
2490 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2491 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2493 * config/obj-coff.h: Don't use #elif.
2495 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2496 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2522 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
2523 using ZERO_BASED_SEGMENTS.
2524 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2525 never set segment address for SEG_E2 (.bss) and don't write out
2526 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2527 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2528 definitions, and don't merge tags with non-tags. Check for .bf
2529 rather than just checking whether the second character is b and
2530 the third character is f.
2531 (obj_coff_val): gcc can generate values which we don't handle
2532 correctly; discard information for now, since it only affects the
2533 debugging information.
2534 (tag_find_or_name): Don't insert tags in the symbol table.
2535 (yank_symbols): Don't merge labels.
2536 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2542 relative addends by the segment vaddr.
2543 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
2544 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

2682 could be doing emulation.
2684 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2687 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

2718 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2719 constant will not fit in an immediate field.
2720 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

2757 * Support for i386-sysv.
2758 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

2782 * tc-m68k.c (get_num): make it work for all segments, not just the
2785 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
2787 * configure.in: recognize i386-*-bsd emulation.

2796 * tc-z8k.c: lots of bug fixes
2798 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2800 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2801 #elif, since it is not supported by old compilers.
2802 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2803 couple of expressions in tc-m68k.c.
2805 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2807 * read.c (cons): If NO_RELOC is defined, use it.
2809 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2811 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2813 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2814 local labels to start with a .) and set REGISTER_PREFIX to %.
2815 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2817 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
2819 * messages.c: Comment changes.
2821 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
2823 * as.h: Test if __STDC__ is defined only, don't test its value.
2824 * messages.c: If __STDC__ is not defined, define NO_STDARG.

2828 * listing.c (debugging_pseudo): Add stabs and stabn as things to
2831 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2833 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2834 sections starting from zero, rather than making them consecutive.
2835 This makes subsequent reloc calculations easier, esp if the object
2836 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2837 allocate lcomm in .data rather than in .bss. It seems that some
2838 tools can't cope with a non-zero sized bss before linkage.
2840 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2842 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2843 throughout. That enum no longer means what we thought it meant.
2845 * tc-m68k.c (md_assemble, md_parse_option): Handle new
2846 "-mno-688[58]1" options.
2848 * tc-m68k.c: Added CPU32 support.
2850 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2852 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
2854 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
2856 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
2857 Change LIBDEPS dependence to LIBS.
2859 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
2861 * Makefile.in (install): if $(tooldir) exists, install as in
2864 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2866 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2867 .word is < -32768 or > 32767. The -J flag causes the error to be
2868 ignored. This is to catch over-sized switches generated by gcc on
2869 systems which don't support the broken .word hack.
2870 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2871 write.c (fixup_segment): check for signed .word overflow if
2872 WARN_SIGNED_OVERFLOW_WORD.
2874 * write.c (fixup_segment): fixed missing parens in expression
2875 checking for byte or word overflow.
2877 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
2878 obj-coffbfd.c (fixup_segment): check for signed .word overflow if

2886 Support for i386 coff
2887 * obj-coffbfd.h : added stuff
2888 * tc-i386.c (tc_coff_fix2rtype): new function
2889 * tc-i386.h : new coff defines
2891 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
2893 * input-scrub.c (input_scrub_push): call input_file_begin, not
2895 messages.c (as_perror): print ": " between the passed in error and
2896 the strerror, like perror does.
2898 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

2905 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2906 Motorola and MIT syntax; gas can now assemble either type of

2988 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2989 written with indirection on the last two operands, which can be
2990 either data or address registers. Added a new operand type 'r'
2991 which accepts either register type. Added '(' to notend stuff in
2992 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

3333 * expr.c: If an expression is single comma, then return with
3334 SEG_ABSENT rather than an error - since the sparc front end does
3335 really strange things with things like fbge,a
3337 * as.h: include bfd.h if using many sections
3338 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so

3352 * expr.c: Much rewriting, to accomodate MRI syntax for
3353 expressions. Also easier to read now.
3354 * listing.c: Put back defuns
3355 * read.c: modified to accept MRI syntax, put back listing pseudo
3356 ops so that an assembler built with NO_LISTING ignores list ops
3358 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
3359 machine is a SPARC or a 29K.
3360 * config/obj-aout.c: added s_sect pseudo op
3361 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3362 fill in the timestamp.
3363 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3364 anymore, define all the relocs which the tc-<x> bit will use so we
3365 can translate from them to the coff types.
3366 * config/tc-a29k.c: reloc_type isn't ane enum any more
3367 * config/tc-m68k.c: Added NO_RELOC definition.

3386 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3387 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3388 generate these sections. .align: will use NOP_OPCODE or 0
3389 for padding. This is just for being nice to the
3392 * expr.c (operand): changed to generate local label "\001L0"
3393 starting with a ^A so that it is recognized as a local label.
3395 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3397 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3398 i/o opcodes - inb, inw, outb and outw. string manipulation with
3399 att syntax - scmp, slod, smov, ssca, ssto.
3401 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3402 to just after .file .
3404 In obj_crawl_symbol_chain() where it tries to put the external
3405 symbols apart, with the condition:
3406 (!S_IS_DEFINED(symbolP) &&
3407 !S_IS_DEBUG(symbolP) &&
3408 !SF_GET_STATICS(symbolP))
3409 it was moving too many symbols out. So I switch it back to the
3411 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3413 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3414 so that we don't use the F_RELFLG which make the linker complain
3415 that somebody has stripped the relocation info.
3417 Also, the AIX ld program require that the relocation table
3418 is sorted by r_vaddr like the standard ATT assembler does.
3420 [he also changed the sizeof(struct ...)'s into the coff
3421 style FOOSZ macros. I'm not sure this is right, but I can't
3422 remember why. xoxorich.]

3426 * Makefile.in, configure.in, doc: use the doc. Build it, install
3429 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3431 * read.c: white space and comments only.
3433 * configure.in: use the new atof-ns32.c for ns32k.
3435 * write.c: comment change only.
3437 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3438 aren't yet integrated.
3440 * tc-i860.[hc]: blew off the dust. Something must still be done
3441 about conflicting relocation types.
3443 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3446 * tc-i960.c, tc-sparc.c: white space and comments only.
3448 * tc-a29k.h: delete duplicate macro definition.
3450 * new file atof-ns32k.c copied from hack's last unreleased gas.
3452 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3454 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3457 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3458 ChangeLog's prior to this are sketchy at best. I have logs.
3459 They just aren't ChangeLogs.
