327 through inclusion of tc-hppa.h. Delete all forward declarations
328 for functions only used within tc-hppa.c, likewise for structures,
329 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
330 conditional code in a few small places.
332 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
333 structures, global variables, forward declarations together.

335 conditional code -- try to group conditional code together
336 into a few places. Make all functions and variables which
337 are only used within tc-hppa.c static. PARAMize all functions.
338 Add comments to functions. Delete unused functions, variables,
339 #defines, etc. Delete unused members within structures. Delete
340 ldil;ble hacks -- it is believed they were installed to work
341 around old gas bugs. Avoid using mixed case for local
342 functions, variables, and structures. Fix formatting problems
343 not found by GNU-indent. Add FIXME notices for things which
344 should be worked on the near future. Delete lots of old
345 useless (1.36 PA-SOM) code.

418 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
420 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
421 ELF, since the ELF object format does not have these type of
422 relocations. Change the abort into as as_bad and return
423 BFD_RELOC_NONE to silence compiler warnings.
424 (md_assemble): Keep track of the instruction size. Allow white
425 space between the $ and the constant for compatibility with older
426 gases and other assemblers.
427 (i386_operand): Skip spaces between $ and expression.

1423 are also magic, and have special default flag settings.
1424 (obj_elf_frob_symbol): Since the return value from this function
1425 isn't used, don't bother calling obj_elf_write_symbol_p, since it
1426 doesn't accomplish anything else.
1428 * config/tc-sparc.c (md_section_align): Round up section size only
1431 * symbols.c: Don't define DEBUG by default.

1435 * write.c (fix_new_exp): Handle a O_uminus expression.
1437 * expr.c (expr): Don't let absolute_section override
1438 undefined_section for the return value.
1440 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
1441 pseudo-op with a poc_handler field of NULL, ignore it and treat it
1442 as an instruction instead.
1443 * config/tc-m88k.c (md_pseudo_table): Add "set" with a NULL
1446 * config/tc-h8500.c (md_begin): Use a local variable when
1447 initializing md_relax_table to avoid warnings about modifying a
1448 supposedly const data structure.

1458 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
1459 case to set obj_format=elf. Must go before i386-*-sysv* case that
1460 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
1461 *-*-solaris case, and move to before *-sysv* case that wants to
1462 set obj_format to coff.
1463 * config/tc-i386.c (i386_operand): Change all 'exp.X_op' to
1465 * config/tc-i386.c (md_apply_fix): Fix valp to be 'valueT *' for

1480 Output the low 16 bits for RELOC_HI16, not the high 16 bits.
1481 * config/obj-coffbfd.c (do_relocs_for): If TC_M88K, set the
1482 r_offset field of the reloc to the fixup offset.

1486 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1488 * Extensive changes to permit symbols to contain any expression
1489 type and to delay the computation of the expression until the
1490 value is actually needed. This permits setting symbols to values
1491 calculated based on object code size. Expressions were changed to
1492 no longer be in a section, to stop the overloading of segment and
1493 expression type that previously occurred.
1495 * as.c (big_section, pass1_section, diff_section, absent_section):
1497 (expr_section): Added (used for dummy symbols which hold
1498 intermediate expression values).

1581 (previous_section, previous_subsection): New vars.
1582 (obj_elf_section): Save current place in case DWARF code wants us
1583 to pop back to it. Handle unquoted section name as well as quoted
1584 section name. Don't crash on invalid strings.
1585 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
1588 * config/obj-elf.h: Don't include struc-symbol.h.

1668 * config/obj-coffbfd.c (fixup_segment): If TC_M88K, don't adjust
1669 by md_pcrel_from if we are relocating against a symbol (we still
1670 need md_pcrel_from for a PC relative relocation within the same

1673 (omagic): Removed unused variable.
1675 * Preliminary support for m88k-coff.

1697 sy_resolved and sy_resolving single bit fields.
1698 * symbols.c (symbol_new): Don't initialize sy_forward field.

2862 lines; I don't think that can be done portably.
2863 * config/tc-mips.c (macro): Use $AT if target register is zero in
2864 load instruction, which it can be for a floating point load.

2990 * read.c (s_ignore): Don't declare is_end_of_line. It's
2991 redundant, and triggers a VMS gcc compiler bug.
2993 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
2994 current segment as an argument. (Ignored in all cases but VMS.)
2995 All callers and definitions changed.

3328 (which will be declared in obj-vms.h).
3329 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3330 Fix arguments to VMS_write_object_file.
3331 * config-gas.com: New file. Script for VMS systems to set up the
3332 configuration to build gas for VMS, and create config.status.
3333 * make-gas.com: Redone to work with new scheme.
3334 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3336 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
3337 will swap bytes if needed on a big endian system. Use throughout
3339 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3340 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3341 types of malformed stabs. Change parsing algorithm so that we are
3342 more certain of having all of the information that we need on hand.
3343 * obj-vms.c (final_forward_reference): New function, used to help
3344 resolve the data types of as many struct elements as possible
3345 when some part of the struct is not fully defined by the compiler.
3346 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
3348 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3349 as symbols as well in the object file. Look for external functions
3350 that start with "__vt.", and turn them into variables, since the
3351 g++ compiler is incapable of doing this.
3352 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3354 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3355 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3356 have the name of the source file yet.
3357 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3359 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3361 * read.c (s_data): Always use "data_section", since it'll map to
3362 SEG_DATA or SEG_E1 if needed.
3363 (s_lcomm): Likewise with bss_section.
3364 (s_fill): Use memset, not bzero.
3366 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3388 (big_section, reg_section, pass1_section, diff_section,
3389 absent_section, text_section, data_section, bss_section): If
3390 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3391 mapping to segT enum values.
3392 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3393 if these are used or defined, if BFD_ASSEMBLER.
3394 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3395 subseg_new split into two functions.
3396 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3398 * as.h (volatile): Don't define if already defined.
3399 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3401 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3402 declare with format attribute for -Wformat checking.
3404 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3406 * app.c, config/tc-*.c: Don't include read.h, since it is already
3409 * These are based on patches from Minh Tran-le
3410 <mtranle@paris.intellicorp.com>.
3411 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3412 obj_format coffbfd and gas_target i386coff for target.
3413 (i[34]86-*-isc*): New host (uses sysv).
3414 * config/i386aix.mt: Removed (no longer used).
3415 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3417 (LDFLAGS): Added, defined as -shlib.
3418 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3419 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3420 (DOT_LABEL_PREFIX): Define.
3421 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3422 name rather than L0\001.
3423 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3425 * symbols.c, symbols.h (local_bss_counter): Removed.

3434 (size_section): Restored sanity check.
3435 (do_relocs_for): Base section address on s_paddr rather than
3436 computing it. Adjust a29k R_IHIHALF special case to account for
3437 section paddr (used to require paddr to be zero). If there are no
3438 reclos, set s_relptr to 0. Set relocation size in object_headers.
3439 (fill_section): Always set s_vaddr here, removing
3440 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3441 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3442 Set STYP_INFO for .comment.

3446 H_{SET,GET}_* macros.
3447 (do_linenos_for): Set lineno size in object_headers.
3448 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3449 set s_vaddr here. If string_byte_count remains 4, set it back to
3450 0, and only write strings out if there are some. Call
3451 fill_section before do_relocs_for and do_linenos_for.
3452 (obj_coff_section): Handle optional quoted second argument giving
3453 section characteristics.
3454 (obj_coff_bss): Added to handle .bss.
3455 (obj_coff_ident): Added to handle .ident (puts string in .comment

3475 (do_scrub_next_char): For \", return " not '.
3476 (symbol_chars): Now const.
3478 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3479 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3481 * config/obj-coff.h: Don't use #elif.
3483 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3484 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

3513 never set segment address for SEG_E2 (.bss) and don't write out
3514 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3515 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3516 definitions, and don't merge tags with non-tags. Check for .bf
3517 rather than just checking whether the second character is b and
3518 the third character is f.
3519 (obj_coff_val): gcc can generate values which we don't handle
3520 correctly; discard information for now, since it only affects the
3521 debugging information.

3523 (yank_symbols): Don't merge labels.
3524 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3802 local labels to start with a .) and set REGISTER_PREFIX to %.
3803 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
3805 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

3821 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3822 sections starting from zero, rather than making them consecutive.
3823 This makes subsequent reloc calculations easier, esp if the object
3824 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3825 allocate lcomm in .data rather than in .bss. It seems that some
3826 tools can't cope with a non-zero sized bss before linkage.
3828 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3830 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
3831 throughout. That enum no longer means what we thought it meant.

3852 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
3854 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3855 .word is < -32768 or > 32767. The -J flag causes the error to be
3856 ignored. This is to catch over-sized switches generated by gcc on
3857 systems which don't support the broken .word hack.
3858 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
3859 write.c (fixup_segment): check for signed .word overflow if
3860 WARN_SIGNED_OVERFLOW_WORD.
3862 * write.c (fixup_segment): fixed missing parens in expression
3863 checking for byte or word overflow.

3889 From Steve Chamberlain:
3890 Makefile.in: Handle m68*-*-coff*.
3891 read.c, read.h: add mult argument to s_space
3893 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
3894 Motorola and MIT syntax; gas can now assemble either type of
3896 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

3903 (fixup_segment) set fx_subsy to 0.
3904 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
3906 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
3909 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3911 * Makefile.in (LIBS): Include opcode library.

3938 * config/tc-m68k.c (init_table): Now const. Always include 68851
3939 data, so that "bc" is available to 68040 cache instructions.
3940 Added "tt0", "tt1", and 68ec030 variants.
3941 (md_assemble): Complain if 68000 (only) and 68881 are specified.
3942 (enum _register): Added TT0, TT1.
3943 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
3944 line number correctly in "internal error" messages. Don't print
3945 architecture-mismatch message for operand errors.

3970 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
3971 has already been formatted (but may still contain %-characters).
3974 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
3976 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
3977 written with indirection on the last two operands, which can be
3978 either data or address registers. Added a new operand type 'r'
3979 which accepts either register type. Added '(' to notend stuff in
3980 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4299 * Makefile.in (strerror.o): Add rule so that broken Sun make can
4302 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4304 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4306 * expr.c (operand): if can't work out what sort of operand it is,
4307 then look through FLT_CHARS for a hint.
4309 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4311 * Makefile.in, configure.in: removed traces of namesubdir,
4312 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4313 copyrights to '92, changed some from Cygnus to FSF.
4315 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4316 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4317 copyrights to '92, changed some from Cygnus to FSF.
4319 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4321 * expr.c: If an expression is single comma, then return with
4322 SEG_ABSENT rather than an error - since the sparc front end does
4323 really strange things with things like fbge,a
4325 * as.h: include bfd.h if using many sections
4326 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4327 local labels didn't work.
4328 * listing.c (list_symbol_table): don't core dump when there's no
4330 * write.c, write.h: call fix_new with the right number of args on
4332 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4335 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4337 * app.c: MRI compatibility - allow single quote to start a string.
4338 * as.c: fix typo recently introduced.
4339 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4340 * expr.c: Much rewriting, to accomodate MRI syntax for
4341 expressions. Also easier to read now.
4342 * listing.c: Put back defuns
4343 * read.c: modified to accept MRI syntax, put back listing pseudo
4344 ops so that an assembler built with NO_LISTING ignores list ops
4346 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4347 machine is a SPARC or a 29K.
4348 * config/obj-aout.c: added s_sect pseudo op
4349 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4350 fill in the timestamp.
4351 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4352 anymore, define all the relocs which the tc-<x> bit will use so we
4353 can translate from them to the coff types.
4354 * config/tc-a29k.c: reloc_type isn't ane enum any more
4355 * config/tc-m68k.c: Added NO_RELOC definition.
4357 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4359 * Makefile.in: put header files before C source for TAGS; remove
4360 references to non-existent syscalls.h.
4362 * read.c, write.c subsegs.c: back out the .bss changes.
4364 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4366 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4370 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4372 * symbols.c (local_label_name): symbols now start with ^A.
4374 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4375 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4376 generate these sections. .align: will use NOP_OPCODE or 0
4377 for padding. This is just for being nice to the
4380 * expr.c (operand): changed to generate local label "\001L0"
4381 starting with a ^A so that it is recognized as a local label.
4383 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4385 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4386 i/o opcodes - inb, inw, outb and outw. string manipulation with
4387 att syntax - scmp, slod, smov, ssca, ssto.
4389 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4390 to just after .file .
4392 In obj_crawl_symbol_chain() where it tries to put the external
4393 symbols apart, with the condition:
4394 (!S_IS_DEFINED(symbolP) &&
4395 !S_IS_DEBUG(symbolP) &&
4396 !SF_GET_STATICS(symbolP))
4397 it was moving too many symbols out. So I switch it back to the
4399 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4401 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4402 so that we don't use the F_RELFLG which make the linker complain
4403 that somebody has stripped the relocation info.
4405 Also, the AIX ld program require that the relocation table
4406 is sorted by r_vaddr like the standard ATT assembler does.
4408 [he also changed the sizeof(struct ...)'s into the coff
4409 style FOOSZ macros. I'm not sure this is right, but I can't
4410 remember why. xoxorich.]
4412 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4414 * Makefile.in, configure.in, doc: use the doc. Build it, install
4417 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4419 * read.c: white space and comments only.
4421 * configure.in: use the new atof-ns32.c for ns32k.
4423 * write.c: comment change only.
4425 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4426 aren't yet integrated.
4428 * tc-i860.[hc]: blew off the dust. Something must still be done
4429 about conflicting relocation types.
4431 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4434 * tc-i960.c, tc-sparc.c: white space and comments only.
4436 * tc-a29k.h: delete duplicate macro definition.
4438 * new file atof-ns32k.c copied from hack's last unreleased gas.
4440 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4442 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4445 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4446 ChangeLog's prior to this are sketchy at best. I have logs.
4447 They just aren't ChangeLogs.
