160 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
161 the table, require that the one without bit 0x1000000 set come

281 * config/tc-sparc.c (md_end): Function deleted.

294 through inclusion of tc-hppa.h. Delete all forward declarations
295 for functions only used within tc-hppa.c, likewise for structures,
296 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
297 conditional code in a few small places.
299 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
300 structures, global variables, forward declarations together.
301 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
302 conditional code -- try to group conditional code together
303 into a few places. Make all functions and variables which
304 are only used within tc-hppa.c static. PARAMize all functions.
305 Add comments to functions. Delete unused functions, variables,
306 #defines, etc. Delete unused members within structures. Delete
307 ldil;ble hacks -- it is believed they were installed to work
308 around old gas bugs. Avoid using mixed case for local
309 functions, variables, and structures. Fix formatting problems
310 not found by GNU-indent. Add FIXME notices for things which
311 should be worked on the near future. Delete lots of old
312 useless (1.36 PA-SOM) code.

341 a multiple of the section alignment rather than always a
344 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
345 bits are zero (eg they specify no relocations), then do not even
346 bother adding their entries to thesymextn section.

385 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
387 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
388 ELF, since the ELF object format does not have these type of
389 relocations. Change the abort into as as_bad and return
390 BFD_RELOC_NONE to silence compiler warnings.
391 (md_assemble): Keep track of the instruction size. Allow white
392 space between the $ and the constant for compatibility with older
393 gases and other assemblers.
394 (i386_operand): Skip spaces between $ and expression.
395 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

1426 case to set obj_format=elf. Must go before i386-*-sysv* case that
1427 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
1428 *-*-solaris case, and move to before *-sysv* case that wants to

1455 * Extensive changes to permit symbols to contain any expression
1456 type and to delay the computation of the expression until the
1457 value is actually needed. This permits setting symbols to values
1458 calculated based on object code size. Expressions were changed to
1459 no longer be in a section, to stop the overloading of segment and
1460 expression type that previously occurred.
1462 * as.c (big_section, pass1_section, diff_section, absent_section):
1464 (expr_section): Added (used for dummy symbols which hold

1485 (fix_new): Removed sub_symbol argument.
1486 (fix_new_exp): New function, takes expression argument.

1548 (previous_section, previous_subsection): New vars.
1549 (obj_elf_section): Save current place in case DWARF code wants us
1550 to pop back to it. Handle unquoted section name as well as quoted
1551 section name. Don't crash on invalid strings.
1552 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
1555 * config/obj-elf.h: Don't include struc-symbol.h.
1556 (obj_elf_frob_symbol): Declare arg as struct symbol *.

1595 use new macro tc_frob_label.
1596 * config/tc-hppa.h (tc_frob_label): Define.
1598 * config/tc-mips.c: Many changes to support simple assembler

1635 * config/obj-coffbfd.c (fixup_segment): If TC_M88K, don't adjust
1636 by md_pcrel_from if we are relocating against a symbol (we still
1637 need md_pcrel_from for a PC relative relocation within the same

1640 (omagic): Removed unused variable.
1642 * Preliminary support for m88k-coff.

1664 sy_resolved and sy_resolving single bit fields.
1665 * symbols.c (symbol_new): Don't initialize sy_forward field.

2800 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
2802 * Makefile.in: add dvi target; as-$(config).texinfo might live in
2803 srcdir, might be in objdir.

2827 dropping a space immediately following an identifier.

2830 * config/tc-mips.c (macro): Use $AT if target register is zero in
2831 load instruction, which it can be for a floating point load.

2905 prototypes for all static functions. Moved existing minimal
2906 debugging format support info #ifndef OBJ_ECOFF blocks.

2958 redundant, and triggers a VMS gcc compiler bug.
2960 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
2961 current segment as an argument. (Ignored in all cases but VMS.)
2962 All callers and definitions changed.

3279 (operand): Treat zero byte as end-of-operand.
3281 * configure.in (per-target): Look for with_bfd_assembler option.
3282 For now, only accept "no", until the merge is done.
3284 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3285 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
3286 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
3287 * read.c: Finish conversion to S_* macros in the VMS only
3288 parts of the program. Add "const" modifier to hex_value.
3289 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
3291 * expr.c: Add "const" modifier to hex_value.
3292 * symbols.c: Finish conversion to S_* macros in the VMS only
3293 parts of the program. Add "const" modifier to
3294 md_[long,short]_jump_size. Remove declaration of const_flag
3295 (which will be declared in obj-vms.h).
3296 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3297 Fix arguments to VMS_write_object_file.
3298 * config-gas.com: New file. Script for VMS systems to set up the

3311 resolve the data types of as many struct elements as possible
3312 when some part of the struct is not fully defined by the compiler.
3313 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
3315 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3316 as symbols as well in the object file. Look for external functions

3318 g++ compiler is incapable of doing this.
3319 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3321 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

3328 * read.c (s_data): Always use "data_section", since it'll map to
3329 SEG_DATA or SEG_E1 if needed.
3330 (s_lcomm): Likewise with bss_section.
3331 (s_fill): Use memset, not bzero.
3333 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
3335 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

3345 * Changes for BFD_ASSEMBLER:
3346 * obj.h (obj_crawl_symbol_chain): Declare only if not
3348 (obj_header_append, obj_pre_write_hook): Ditto.
3349 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
3350 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
3351 (segment_name) If BFD_ASSEMBLER, look up BFD section name;

3355 (big_section, reg_section, pass1_section, diff_section,
3356 absent_section, text_section, data_section, bss_section): If
3357 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3358 mapping to segT enum values.

3360 if these are used or defined, if BFD_ASSEMBLER.
3361 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

3366 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3368 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3369 declare with format attribute for -Wformat checking.
3371 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3373 * app.c, config/tc-*.c: Don't include read.h, since it is already
3376 * These are based on patches from Minh Tran-le
3377 <mtranle@paris.intellicorp.com>.
3378 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3379 obj_format coffbfd and gas_target i386coff for target.
3380 (i[34]86-*-isc*): New host (uses sysv).
3381 * config/i386aix.mt: Removed (no longer used).
3382 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3384 (LDFLAGS): Added, defined as -shlib.
3385 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3386 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3387 (DOT_LABEL_PREFIX): Define.
3388 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3389 name rather than L0\001.
3390 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3392 * symbols.c, symbols.h (local_bss_counter): Removed.
3393 * write.c (write_object_file): bss no longer uses

3401 (size_section): Restored sanity check.
3402 (do_relocs_for): Base section address on s_paddr rather than
3403 computing it. Adjust a29k R_IHIHALF special case to account for
3404 section paddr (used to require paddr to be zero). If there are no
3405 reclos, set s_relptr to 0. Set relocation size in object_headers.
3406 (fill_section): Always set s_vaddr here, removing
3407 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3408 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3409 Set STYP_INFO for .comment.

3414 (do_linenos_for): Set lineno size in object_headers.
3415 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3416 set s_vaddr here. If string_byte_count remains 4, set it back to
3417 0, and only write strings out if there are some. Call
3418 fill_section before do_relocs_for and do_linenos_for.
3419 (obj_coff_section): Handle optional quoted second argument giving
3420 section characteristics.
3421 (obj_coff_bss): Added to handle .bss.
3422 (obj_coff_ident): Added to handle .ident (puts string in .comment
3424 (obj_coff_lcomm): Put common symbols in .bss, not .data.
3425 (fixup_mdeps): Change to segment. Call frag_wane after
3427 (fixup_segment): Explicitly check S_IS_COMMON before making 386
3428 adjustment (already happened only for common symbols, but this is
3430 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

3442 (do_scrub_next_char): For \", return " not '.
3443 (symbol_chars): Now const.
3445 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3446 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3448 * config/obj-coff.h: Don't use #elif.
3450 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3451 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
3453 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

3478 using ZERO_BASED_SEGMENTS.
3479 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3480 never set segment address for SEG_E2 (.bss) and don't write out
3481 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3482 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3483 definitions, and don't merge tags with non-tags. Check for .bf
3484 rather than just checking whether the second character is b and
3485 the third character is f.
3486 (obj_coff_val): gcc can generate values which we don't handle
3487 correctly; discard information for now, since it only affects the
3488 debugging information.

3490 (yank_symbols): Don't merge labels.
3491 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3636 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
3637 could be doing emulation.
3639 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3642 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

3671 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
3673 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
3674 constant will not fit in an immediate field.
3675 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
3677 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

3710 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
3712 * Support for i386-sysv.
3713 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

3750 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
3751 * tc-z8k.c: lots of bug fixes
3753 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
3755 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3756 #elif, since it is not supported by old compilers.
3757 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3758 couple of expressions in tc-m68k.c.
3760 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3762 * read.c (cons): If NO_RELOC is defined, use it.
3764 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
3766 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
3768 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3769 local labels to start with a .) and set REGISTER_PREFIX to %.
3770 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
3772 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
3774 * messages.c: Comment changes.
3776 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

3786 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
3788 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3789 sections starting from zero, rather than making them consecutive.
3790 This makes subsequent reloc calculations easier, esp if the object
3791 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3792 allocate lcomm in .data rather than in .bss. It seems that some
3793 tools can't cope with a non-zero sized bss before linkage.
3795 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3797 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
3798 throughout. That enum no longer means what we thought it meant.

3821 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3822 .word is < -32768 or > 32767. The -J flag causes the error to be
3823 ignored. This is to catch over-sized switches generated by gcc on
3824 systems which don't support the broken .word hack.
3825 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.

3905 * config/tc-m68k.c (init_table): Now const. Always include 68851
3906 data, so that "bc" is available to 68040 cache instructions.
3907 Added "tt0", "tt1", and 68ec030 variants.
3908 (md_assemble): Complain if 68000 (only) and 68881 are specified.

3937 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
3938 has already been formatted (but may still contain %-characters).
3941 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
3943 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
3944 written with indirection on the last two operands, which can be
3945 either data or address registers. Added a new operand type 'r'
3946 which accepts either register type. Added '(' to notend stuff in
3947 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4304 * app.c: MRI compatibility - allow single quote to start a string.
4305 * as.c: fix typo recently introduced.
4306 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4307 * expr.c: Much rewriting, to accomodate MRI syntax for
4308 expressions. Also easier to read now.
4309 * listing.c: Put back defuns
4310 * read.c: modified to accept MRI syntax, put back listing pseudo
4311 ops so that an assembler built with NO_LISTING ignores list ops
4313 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4314 machine is a SPARC or a 29K.
4315 * config/obj-aout.c: added s_sect pseudo op
4316 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4317 fill in the timestamp.
4318 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4319 anymore, define all the relocs which the tc-<x> bit will use so we
4320 can translate from them to the coff types.
4321 * config/tc-a29k.c: reloc_type isn't ane enum any more
4322 * config/tc-m68k.c: Added NO_RELOC definition.

4326 * Makefile.in: put header files before C source for TAGS; remove
4327 references to non-existent syscalls.h.
4329 * read.c, write.c subsegs.c: back out the .bss changes.
4331 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4333 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4337 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4339 * symbols.c (local_label_name): symbols now start with ^A.
4341 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4342 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4343 generate these sections. .align: will use NOP_OPCODE or 0
4344 for padding. This is just for being nice to the
4347 * expr.c (operand): changed to generate local label "\001L0"
4348 starting with a ^A so that it is recognized as a local label.
4350 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4352 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4353 i/o opcodes - inb, inw, outb and outw. string manipulation with
4354 att syntax - scmp, slod, smov, ssca, ssto.
4356 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4357 to just after .file .
4359 In obj_crawl_symbol_chain() where it tries to put the external
4360 symbols apart, with the condition:
4361 (!S_IS_DEFINED(symbolP) &&
4362 !S_IS_DEBUG(symbolP) &&
4363 !SF_GET_STATICS(symbolP))
4364 it was moving too many symbols out. So I switch it back to the
4366 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4368 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4369 so that we don't use the F_RELFLG which make the linker complain
4370 that somebody has stripped the relocation info.
4372 Also, the AIX ld program require that the relocation table
4373 is sorted by r_vaddr like the standard ATT assembler does.
4375 [he also changed the sizeof(struct ...)'s into the coff
4376 style FOOSZ macros. I'm not sure this is right, but I can't
4377 remember why. xoxorich.]
4379 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4381 * Makefile.in, configure.in, doc: use the doc. Build it, install
4384 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4386 * read.c: white space and comments only.
4388 * configure.in: use the new atof-ns32.c for ns32k.
4390 * write.c: comment change only.
4392 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4393 aren't yet integrated.
4395 * tc-i860.[hc]: blew off the dust. Something must still be done
4396 about conflicting relocation types.
4398 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4401 * tc-i960.c, tc-sparc.c: white space and comments only.
4403 * tc-a29k.h: delete duplicate macro definition.
4405 * new file atof-ns32k.c copied from hack's last unreleased gas.
4407 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4409 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4412 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4413 ChangeLog's prior to this are sketchy at best. I have logs.
4414 They just aren't ChangeLogs.
