1186 default is to assume production environment, and reject configs
1187 still being worked on. Mark Elf configurations (except sparc and
1188 i386) as developmental. Deleted cases matching some generic names
1189 in favor of more specific names. (E.g., when we get Alpha

1206 through inclusion of tc-hppa.h. Delete all forward declarations
1207 for functions only used within tc-hppa.c, likewise for structures,
1208 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1209 conditional code in a few small places.
1211 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1212 structures, global variables, forward declarations together.

1214 conditional code -- try to group conditional code together
1215 into a few places. Make all functions and variables which
1216 are only used within tc-hppa.c static. PARAMize all functions.
1217 Add comments to functions. Delete unused functions, variables,
1218 #defines, etc. Delete unused members within structures. Delete
1219 ldil;ble hacks -- it is believed they were installed to work
1220 around old gas bugs. Avoid using mixed case for local
1221 functions, variables, and structures. Fix formatting problems
1222 not found by GNU-indent. Add FIXME notices for things which
1223 should be worked on the near future. Delete lots of old
1224 useless (1.36 PA-SOM) code.

1297 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1299 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1300 ELF, since the ELF object format does not have these type of
1301 relocations. Change the abort into as as_bad and return
1302 BFD_RELOC_NONE to silence compiler warnings.
1303 (md_assemble): Keep track of the instruction size. Allow white
1304 space between the $ and the constant for compatibility with older
1305 gases and other assemblers.
1306 (i386_operand): Skip spaces between $ and expression.
1307 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

2367 * Extensive changes to permit symbols to contain any expression
2368 type and to delay the computation of the expression until the
2369 value is actually needed. This permits setting symbols to values
2370 calculated based on object code size. Expressions were changed to
2371 no longer be in a section, to stop the overloading of segment and
2372 expression type that previously occurred.
2374 * as.c (big_section, pass1_section, diff_section, absent_section):
2376 (expr_section): Added (used for dummy symbols which hold

2460 (previous_section, previous_subsection): New vars.
2461 (obj_elf_section): Save current place in case DWARF code wants us
2462 to pop back to it. Handle unquoted section name as well as quoted
2463 section name. Don't crash on invalid strings.
2464 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
2467 * config/obj-elf.h: Don't include struc-symbol.h.

2576 sy_resolved and sy_resolving single bit fields.
2577 * symbols.c (symbol_new): Don't initialize sy_forward field.

3712 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3714 * Makefile.in: add dvi target; as-$(config).texinfo might live in

3769 to be on a single line.
3771 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3773 * Makefile.in (config.h): Create file, writing out definitions of

3775 (ALL_CFLAGS): No longer define TARGET_CPU.
3777 * Makefile.in (check): Print a message, instead of quitting
3780 * as.c (main): Don't catch any signals, for now.

3817 prototypes for all static functions. Moved existing minimal
3818 debugging format support info #ifndef OBJ_ECOFF blocks.

3867 * make-gas.com: Find obstack.obj if it's not in the current
3869 * read.c (s_ignore): Don't declare is_end_of_line. It's
3870 redundant, and triggers a VMS gcc compiler bug.
3872 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3873 current segment as an argument. (Ignored in all cases but VMS.)
3874 All callers and definitions changed.

4187 * expr.c (operand): If character other than comma or newline is a
4188 logical end-of-line character, use the newline case.
4189 From Eric Youngdale:
4190 (operand): Set X_add_number field for floating-point numbers.
4191 (operand): Treat zero byte as end-of-operand.
4193 * configure.in (per-target): Look for with_bfd_assembler option.
4194 For now, only accept "no", until the merge is done.
4196 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4197 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4198 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4199 * read.c: Finish conversion to S_* macros in the VMS only
4200 parts of the program. Add "const" modifier to hex_value.
4201 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4203 * expr.c: Add "const" modifier to hex_value.
4204 * symbols.c: Finish conversion to S_* macros in the VMS only
4205 parts of the program. Add "const" modifier to
4206 md_[long,short]_jump_size. Remove declaration of const_flag
4207 (which will be declared in obj-vms.h).
4208 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4209 Fix arguments to VMS_write_object_file.
4210 * config-gas.com: New file. Script for VMS systems to set up the
4211 configuration to build gas for VMS, and create config.status.
4212 * make-gas.com: Redone to work with new scheme.
4213 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4215 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4216 will swap bytes if needed on a big endian system. Use throughout
4218 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4219 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4220 types of malformed stabs. Change parsing algorithm so that we are
4221 more certain of having all of the information that we need on hand.
4222 * obj-vms.c (final_forward_reference): New function, used to help
4223 resolve the data types of as many struct elements as possible
4224 when some part of the struct is not fully defined by the compiler.
4225 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
4227 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4228 as symbols as well in the object file. Look for external functions
4229 that start with "__vt.", and turn them into variables, since the
4230 g++ compiler is incapable of doing this.
4231 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4233 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4234 * input-scrub.c (as_where): Fix bug where as would crash if we did not

4255 * config/obj-coffbfd.h (segment_name): Ditto.
4257 * Changes for BFD_ASSEMBLER:
4258 * obj.h (obj_crawl_symbol_chain): Declare only if not
4260 (obj_header_append, obj_pre_write_hook): Ditto.
4261 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
4262 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

4267 (big_section, reg_section, pass1_section, diff_section,
4268 absent_section, text_section, data_section, bss_section): If
4269 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4270 mapping to segT enum values.
4271 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4272 if these are used or defined, if BFD_ASSEMBLER.
4273 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

4278 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4280 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4281 declare with format attribute for -Wformat checking.
4283 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4285 * app.c, config/tc-*.c: Don't include read.h, since it is already
4288 * These are based on patches from Minh Tran-le
4289 <mtranle@paris.intellicorp.com>.
4290 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4291 obj_format coffbfd and gas_target i386coff for target.
4292 (i[34]86-*-isc*): New host (uses sysv).
4293 * config/i386aix.mt: Removed (no longer used).
4294 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4296 (LDFLAGS): Added, defined as -shlib.
4297 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4298 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4299 (DOT_LABEL_PREFIX): Define.
4300 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4301 name rather than L0\001.
4302 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4304 * symbols.c, symbols.h (local_bss_counter): Removed.
4305 * write.c (write_object_file): bss no longer uses

4313 (size_section): Restored sanity check.
4314 (do_relocs_for): Base section address on s_paddr rather than
4315 computing it. Adjust a29k R_IHIHALF special case to account for
4316 section paddr (used to require paddr to be zero). If there are no
4317 reclos, set s_relptr to 0. Set relocation size in object_headers.
4318 (fill_section): Always set s_vaddr here, removing
4319 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4320 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4321 Set STYP_INFO for .comment.
4322 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4323 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4326 (do_linenos_for): Set lineno size in object_headers.
4327 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4328 set s_vaddr here. If string_byte_count remains 4, set it back to
4329 0, and only write strings out if there are some. Call
4330 fill_section before do_relocs_for and do_linenos_for.
4331 (obj_coff_section): Handle optional quoted second argument giving
4332 section characteristics.
4333 (obj_coff_bss): Added to handle .bss.
4334 (obj_coff_ident): Added to handle .ident (puts string in .comment

4337 (fixup_mdeps): Change to segment. Call frag_wane after
4339 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4340 adjustment (already happened only for common symbols, but this is
4342 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

4354 (do_scrub_next_char): For \", return " not '.
4355 (symbol_chars): Now const.
4357 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4358 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4360 * config/obj-coff.h: Don't use #elif.
4362 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4363 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4365 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

4389 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4390 using ZERO_BASED_SEGMENTS.
4391 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4392 never set segment address for SEG_E2 (.bss) and don't write out
4393 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4394 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4395 definitions, and don't merge tags with non-tags. Check for .bf
4396 rather than just checking whether the second character is b and
4397 the third character is f.
4398 (obj_coff_val): gcc can generate values which we don't handle
4399 correctly; discard information for now, since it only affects the
4400 debugging information.

4402 (yank_symbols): Don't merge labels.
4403 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4548 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
4549 could be doing emulation.
4551 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4554 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4583 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4585 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4586 constant will not fit in an immediate field.
4587 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
4589 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

4624 * Support for i386-sysv.
4625 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4662 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
4663 * tc-z8k.c: lots of bug fixes
4665 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4667 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4668 #elif, since it is not supported by old compilers.
4669 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4670 couple of expressions in tc-m68k.c.
4672 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4674 * read.c (cons): If NO_RELOC is defined, use it.
4676 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4678 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4680 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4681 local labels to start with a .) and set REGISTER_PREFIX to %.
4682 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4684 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
4686 * messages.c: Comment changes.

4698 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4700 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4701 sections starting from zero, rather than making them consecutive.
4702 This makes subsequent reloc calculations easier, esp if the object
4703 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4704 allocate lcomm in .data rather than in .bss. It seems that some
4705 tools can't cope with a non-zero sized bss before linkage.
4707 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4709 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4713 "-mno-688[58]1" options.
4715 * tc-m68k.c: Added CPU32 support.

4731 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4733 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4734 .word is < -32768 or > 32767. The -J flag causes the error to be
4735 ignored. This is to catch over-sized switches generated by gcc on
4736 systems which don't support the broken .word hack.
4737 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4738 write.c (fixup_segment): check for signed .word overflow if

4768 From Steve Chamberlain:
4769 Makefile.in: Handle m68*-*-coff*.
4770 read.c, read.h: add mult argument to s_space
4772 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4773 Motorola and MIT syntax; gas can now assemble either type of

4817 * config/tc-m68k.c (init_table): Now const. Always include 68851
4818 data, so that "bc" is available to 68040 cache instructions.
4819 Added "tt0", "tt1", and 68ec030 variants.
4820 (md_assemble): Complain if 68000 (only) and 68881 are specified.

4849 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4850 has already been formatted (but may still contain %-characters).
4853 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4855 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4856 written with indirection on the last two operands, which can be
4857 either data or address registers. Added a new operand type 'r'
4858 which accepts either register type. Added '(' to notend stuff in
4859 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5220 expressions. Also easier to read now.
5221 * listing.c: Put back defuns
5222 * read.c: modified to accept MRI syntax, put back listing pseudo
5223 ops so that an assembler built with NO_LISTING ignores list ops
5225 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5226 machine is a SPARC or a 29K.
5227 * config/obj-aout.c: added s_sect pseudo op
5228 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5229 fill in the timestamp.
5230 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5231 anymore, define all the relocs which the tc-<x> bit will use so we
5232 can translate from them to the coff types.
5233 * config/tc-a29k.c: reloc_type isn't ane enum any more
5234 * config/tc-m68k.c: Added NO_RELOC definition.

5238 * Makefile.in: put header files before C source for TAGS; remove
5239 references to non-existent syscalls.h.
5241 * read.c, write.c subsegs.c: back out the .bss changes.
5243 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5245 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

5251 * symbols.c (local_label_name): symbols now start with ^A.
5253 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5254 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5255 generate these sections. .align: will use NOP_OPCODE or 0
5256 for padding. This is just for being nice to the
5259 * expr.c (operand): changed to generate local label "\001L0"
5260 starting with a ^A so that it is recognized as a local label.
5262 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5264 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5265 i/o opcodes - inb, inw, outb and outw. string manipulation with
5266 att syntax - scmp, slod, smov, ssca, ssto.
5268 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5269 to just after .file .
5271 In obj_crawl_symbol_chain() where it tries to put the external
5272 symbols apart, with the condition:
5273 (!S_IS_DEFINED(symbolP) &&
5274 !S_IS_DEBUG(symbolP) &&
5275 !SF_GET_STATICS(symbolP))
5276 it was moving too many symbols out. So I switch it back to the
5278 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5280 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5281 so that we don't use the F_RELFLG which make the linker complain
5282 that somebody has stripped the relocation info.
5284 Also, the AIX ld program require that the relocation table
5285 is sorted by r_vaddr like the standard ATT assembler does.
5287 [he also changed the sizeof(struct ...)'s into the coff
5288 style FOOSZ macros. I'm not sure this is right, but I can't
5289 remember why. xoxorich.]
5291 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5293 * Makefile.in, configure.in, doc: use the doc. Build it, install
5296 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5298 * read.c: white space and comments only.
5300 * configure.in: use the new atof-ns32.c for ns32k.
5302 * write.c: comment change only.
5304 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5305 aren't yet integrated.
5307 * tc-i860.[hc]: blew off the dust. Something must still be done
5308 about conflicting relocation types.
5310 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5313 * tc-i960.c, tc-sparc.c: white space and comments only.
5315 * tc-a29k.h: delete duplicate macro definition.
5317 * new file atof-ns32k.c copied from hack's last unreleased gas.
5319 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5321 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5324 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5325 ChangeLog's prior to this are sketchy at best. I have logs.
5326 They just aren't ChangeLogs.
