1235 for keeping or rejecting configurations still under development;
1236 default is to assume production environment, and reject configs
1237 still being worked on. Mark Elf configurations (except sparc and
1238 i386) as developmental. Deleted cases matching some generic names
1239 in favor of more specific names. (E.g., when we get Alpha

1256 through inclusion of tc-hppa.h. Delete all forward declarations
1257 for functions only used within tc-hppa.c, likewise for structures,
1258 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1259 conditional code in a few small places.
1261 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1262 structures, global variables, forward declarations together.

1264 conditional code -- try to group conditional code together
1265 into a few places. Make all functions and variables which
1266 are only used within tc-hppa.c static. PARAMize all functions.
1267 Add comments to functions. Delete unused functions, variables,
1268 #defines, etc. Delete unused members within structures. Delete
1269 ldil;ble hacks -- it is believed they were installed to work
1270 around old gas bugs. Avoid using mixed case for local
1271 functions, variables, and structures. Fix formatting problems
1272 not found by GNU-indent. Add FIXME notices for things which
1273 should be worked on the near future. Delete lots of old
1274 useless (1.36 PA-SOM) code.

1347 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1349 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1350 ELF, since the ELF object format does not have these type of
1351 relocations. Change the abort into as as_bad and return
1352 BFD_RELOC_NONE to silence compiler warnings.
1353 (md_assemble): Keep track of the instruction size. Allow white
1354 space between the $ and the constant for compatibility with older
1355 gases and other assemblers.
1356 (i386_operand): Skip spaces between $ and expression.

2349 Fri Jul 23 13:09:44 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
2351 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
2352 are also magic, and have special default flag settings.
2353 (obj_elf_frob_symbol): Since the return value from this function
2354 isn't used, don't bother calling obj_elf_write_symbol_p, since it
2355 doesn't accomplish anything else.
2357 * config/tc-sparc.c (md_section_align): Round up section size only
2360 * symbols.c: Don't define DEBUG by default.

2366 * expr.c (expr): Don't let absolute_section override
2367 undefined_section for the return value.
2369 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
2370 pseudo-op with a poc_handler field of NULL, ignore it and treat it
2371 as an instruction instead.
2372 * config/tc-m88k.c (md_pseudo_table): Add "set" with a NULL
2375 * config/tc-h8500.c (md_begin): Use a local variable when

2387 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
2388 case to set obj_format=elf. Must go before i386-*-sysv* case that
2389 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
2390 *-*-solaris case, and move to before *-sysv* case that wants to
2391 set obj_format to coff.

2417 * Extensive changes to permit symbols to contain any expression
2418 type and to delay the computation of the expression until the
2419 value is actually needed. This permits setting symbols to values
2420 calculated based on object code size. Expressions were changed to
2421 no longer be in a section, to stop the overloading of segment and
2422 expression type that previously occurred.
2424 * as.c (big_section, pass1_section, diff_section, absent_section):
2426 (expr_section): Added (used for dummy symbols which hold

2510 (previous_section, previous_subsection): New vars.
2511 (obj_elf_section): Save current place in case DWARF code wants us
2512 to pop back to it. Handle unquoted section name as well as quoted
2513 section name. Don't crash on invalid strings.
2514 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
2517 * config/obj-elf.h: Don't include struc-symbol.h.

2602 (omagic): Removed unused variable.
2604 * Preliminary support for m88k-coff.

2626 sy_resolved and sy_resolving single bit fields.
2627 * symbols.c (symbol_new): Don't initialize sy_forward field.

3762 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

3789 dropping a space immediately following an identifier.
3790 * expr.c, write.c: Rewrote assert expressions to not use multiple
3791 lines; I don't think that can be done portably.
3792 * config/tc-mips.c (macro): Use $AT if target register is zero in
3793 load instruction, which it can be for a floating point load.

3867 prototypes for all static functions. Moved existing minimal
3868 debugging format support info #ifndef OBJ_ECOFF blocks.

3917 * make-gas.com: Find obstack.obj if it's not in the current
3919 * read.c (s_ignore): Don't declare is_end_of_line. It's
3920 redundant, and triggers a VMS gcc compiler bug.
3922 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3923 current segment as an argument. (Ignored in all cases but VMS.)
3924 All callers and definitions changed.

4254 * symbols.c: Finish conversion to S_* macros in the VMS only
4255 parts of the program. Add "const" modifier to
4256 md_[long,short]_jump_size. Remove declaration of const_flag
4257 (which will be declared in obj-vms.h).
4258 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4259 Fix arguments to VMS_write_object_file.
4260 * config-gas.com: New file. Script for VMS systems to set up the
4261 configuration to build gas for VMS, and create config.status.
4262 * make-gas.com: Redone to work with new scheme.
4263 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4265 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4266 will swap bytes if needed on a big endian system. Use throughout
4268 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4269 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4270 types of malformed stabs. Change parsing algorithm so that we are
4271 more certain of having all of the information that we need on hand.
4272 * obj-vms.c (final_forward_reference): New function, used to help
4273 resolve the data types of as many struct elements as possible
4274 when some part of the struct is not fully defined by the compiler.
4275 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
4277 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4278 as symbols as well in the object file. Look for external functions
4279 that start with "__vt.", and turn them into variables, since the
4280 g++ compiler is incapable of doing this.
4281 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4283 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4284 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4285 have the name of the source file yet.

4291 SEG_DATA or SEG_E1 if needed.
4292 (s_lcomm): Likewise with bss_section.
4293 (s_fill): Use memset, not bzero.
4295 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4317 (big_section, reg_section, pass1_section, diff_section,
4318 absent_section, text_section, data_section, bss_section): If
4319 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4320 mapping to segT enum values.
4321 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4322 if these are used or defined, if BFD_ASSEMBLER.
4323 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4324 subseg_new split into two functions.
4325 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4327 * as.h (volatile): Don't define if already defined.
4328 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4330 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4331 declare with format attribute for -Wformat checking.
4333 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4335 * app.c, config/tc-*.c: Don't include read.h, since it is already
4338 * These are based on patches from Minh Tran-le
4339 <mtranle@paris.intellicorp.com>.
4340 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4341 obj_format coffbfd and gas_target i386coff for target.
4342 (i[34]86-*-isc*): New host (uses sysv).
4343 * config/i386aix.mt: Removed (no longer used).
4344 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4346 (LDFLAGS): Added, defined as -shlib.
4347 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4348 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4349 (DOT_LABEL_PREFIX): Define.
4350 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4351 name rather than L0\001.
4352 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4354 * symbols.c, symbols.h (local_bss_counter): Removed.

4363 (size_section): Restored sanity check.
4364 (do_relocs_for): Base section address on s_paddr rather than
4365 computing it. Adjust a29k R_IHIHALF special case to account for
4366 section paddr (used to require paddr to be zero). If there are no
4367 reclos, set s_relptr to 0. Set relocation size in object_headers.
4368 (fill_section): Always set s_vaddr here, removing
4369 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4370 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4371 Set STYP_INFO for .comment.

4375 H_{SET,GET}_* macros.
4376 (do_linenos_for): Set lineno size in object_headers.
4377 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4378 set s_vaddr here. If string_byte_count remains 4, set it back to
4379 0, and only write strings out if there are some. Call
4380 fill_section before do_relocs_for and do_linenos_for.
4381 (obj_coff_section): Handle optional quoted second argument giving
4382 section characteristics.
4383 (obj_coff_bss): Added to handle .bss.
4384 (obj_coff_ident): Added to handle .ident (puts string in .comment

4404 (do_scrub_next_char): For \", return " not '.
4405 (symbol_chars): Now const.
4407 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4408 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4410 * config/obj-coff.h: Don't use #elif.
4412 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4413 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

4442 never set segment address for SEG_E2 (.bss) and don't write out
4443 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4444 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4445 definitions, and don't merge tags with non-tags. Check for .bf
4446 rather than just checking whether the second character is b and
4447 the third character is f.
4448 (obj_coff_val): gcc can generate values which we don't handle
4449 correctly; discard information for now, since it only affects the
4450 debugging information.

4452 (yank_symbols): Don't merge labels.
4453 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4728 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4730 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4731 local labels to start with a .) and set REGISTER_PREFIX to %.
4732 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4750 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4751 sections starting from zero, rather than making them consecutive.
4752 This makes subsequent reloc calculations easier, esp if the object
4753 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4754 allocate lcomm in .data rather than in .bss. It seems that some
4755 tools can't cope with a non-zero sized bss before linkage.
4757 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4759 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4781 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4783 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4784 .word is < -32768 or > 32767. The -J flag causes the error to be
4785 ignored. This is to catch over-sized switches generated by gcc on
4786 systems which don't support the broken .word hack.
4787 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4788 write.c (fixup_segment): check for signed .word overflow if
4789 WARN_SIGNED_OVERFLOW_WORD.
4791 * write.c (fixup_segment): fixed missing parens in expression
4792 checking for byte or word overflow.

4818 From Steve Chamberlain:
4819 Makefile.in: Handle m68*-*-coff*.
4820 read.c, read.h: add mult argument to s_space
4822 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge

4833 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4835 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4838 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4840 * Makefile.in (LIBS): Include opcode library.

4867 * config/tc-m68k.c (init_table): Now const. Always include 68851
4868 data, so that "bc" is available to 68040 cache instructions.
4869 Added "tt0", "tt1", and 68ec030 variants.
4870 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4871 (enum _register): Added TT0, TT1.
4872 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4873 line number correctly in "internal error" messages. Don't print
4874 architecture-mismatch message for operand errors.

4899 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4900 has already been formatted (but may still contain %-characters).
4903 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4905 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4906 written with indirection on the last two operands, which can be
4907 either data or address registers. Added a new operand type 'r'
4908 which accepts either register type. Added '(' to notend stuff in
4909 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5224 * write.{c,h} (fix_new): Make these declarations consistent.
5226 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
5228 * Makefile.in (strerror.o): Add rule so that broken Sun make can
5231 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5233 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5235 * expr.c (operand): if can't work out what sort of operand it is,
5236 then look through FLT_CHARS for a hint.
5238 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5240 * Makefile.in, configure.in: removed traces of namesubdir,
5241 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5242 copyrights to '92, changed some from Cygnus to FSF.
5244 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5245 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5246 copyrights to '92, changed some from Cygnus to FSF.
5248 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5250 * expr.c: If an expression is single comma, then return with
5251 SEG_ABSENT rather than an error - since the sparc front end does
5252 really strange things with things like fbge,a
5254 * as.h: include bfd.h if using many sections
5255 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5256 local labels didn't work.
5257 * listing.c (list_symbol_table): don't core dump when there's no
5259 * write.c, write.h: call fix_new with the right number of args on
5261 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5264 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5266 * app.c: MRI compatibility - allow single quote to start a string.
5267 * as.c: fix typo recently introduced.
5268 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5269 * expr.c: Much rewriting, to accomodate MRI syntax for
5270 expressions. Also easier to read now.
5271 * listing.c: Put back defuns
5272 * read.c: modified to accept MRI syntax, put back listing pseudo
5273 ops so that an assembler built with NO_LISTING ignores list ops
5275 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5276 machine is a SPARC or a 29K.
5277 * config/obj-aout.c: added s_sect pseudo op
5278 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5279 fill in the timestamp.
5280 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5281 anymore, define all the relocs which the tc-<x> bit will use so we
5282 can translate from them to the coff types.
5283 * config/tc-a29k.c: reloc_type isn't ane enum any more
5284 * config/tc-m68k.c: Added NO_RELOC definition.
5286 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5288 * Makefile.in: put header files before C source for TAGS; remove
5289 references to non-existent syscalls.h.
5291 * read.c, write.c subsegs.c: back out the .bss changes.
5293 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5295 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5299 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5301 * symbols.c (local_label_name): symbols now start with ^A.
5303 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5304 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5305 generate these sections. .align: will use NOP_OPCODE or 0
5306 for padding. This is just for being nice to the
5309 * expr.c (operand): changed to generate local label "\001L0"
5310 starting with a ^A so that it is recognized as a local label.
5312 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5314 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5315 i/o opcodes - inb, inw, outb and outw. string manipulation with
5316 att syntax - scmp, slod, smov, ssca, ssto.
5318 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5319 to just after .file .
5321 In obj_crawl_symbol_chain() where it tries to put the external
5322 symbols apart, with the condition:
5323 (!S_IS_DEFINED(symbolP) &&
5324 !S_IS_DEBUG(symbolP) &&
5325 !SF_GET_STATICS(symbolP))
5326 it was moving too many symbols out. So I switch it back to the
5328 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5330 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5331 so that we don't use the F_RELFLG which make the linker complain
5332 that somebody has stripped the relocation info.
5334 Also, the AIX ld program require that the relocation table
5335 is sorted by r_vaddr like the standard ATT assembler does.
5337 [he also changed the sizeof(struct ...)'s into the coff
5338 style FOOSZ macros. I'm not sure this is right, but I can't
5339 remember why. xoxorich.]
5341 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5343 * Makefile.in, configure.in, doc: use the doc. Build it, install
5346 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5348 * read.c: white space and comments only.
5350 * configure.in: use the new atof-ns32.c for ns32k.
5352 * write.c: comment change only.
5354 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5355 aren't yet integrated.
5357 * tc-i860.[hc]: blew off the dust. Something must still be done
5358 about conflicting relocation types.
5360 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5363 * tc-i960.c, tc-sparc.c: white space and comments only.
5365 * tc-a29k.h: delete duplicate macro definition.
5367 * new file atof-ns32k.c copied from hack's last unreleased gas.
5369 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5371 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5374 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5375 ChangeLog's prior to this are sketchy at best. I have logs.
5376 They just aren't ChangeLogs.
