1014 OPTIONAL_REGISTER_PREFIX if either is already defined.
1016 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
1018 * configure.in: Set bfd_gas for all sparc targets. Added facility
1019 for keeping or rejecting configurations still under development;
1020 default is to assume production environment, and reject configs
1021 still being worked on. Mark Elf configurations (except sparc and
1022 i386) as developmental. Deleted cases matching some generic names
1023 in favor of more specific names. (E.g., when we get Alpha
1024 support, we'll still only support VMS for Vax.)

1040 through inclusion of tc-hppa.h. Delete all forward declarations
1041 for functions only used within tc-hppa.c, likewise for structures,
1042 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1043 conditional code in a few small places.
1045 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1046 structures, global variables, forward declarations together.
1047 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
1048 conditional code -- try to group conditional code together
1049 into a few places. Make all functions and variables which
1050 are only used within tc-hppa.c static. PARAMize all functions.
1051 Add comments to functions. Delete unused functions, variables,
1052 #defines, etc. Delete unused members within structures. Delete
1053 ldil;ble hacks -- it is believed they were installed to work
1054 around old gas bugs. Avoid using mixed case for local
1055 functions, variables, and structures. Fix formatting problems
1056 not found by GNU-indent. Add FIXME notices for things which
1057 should be worked on the near future. Delete lots of old
1058 useless (1.36 PA-SOM) code.

1075 * config/tc-hppa.c: Likewise.
1077 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1078 of elf32_symbol_type.
1079 (pa_export_args): Likewise.
1080 (elf_hppa_final_processing): Likewise.
1081 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

1087 a multiple of the section alignment rather than always a
1090 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

1131 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1133 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1134 ELF, since the ELF object format does not have these type of
1135 relocations. Change the abort into as as_bad and return
1136 BFD_RELOC_NONE to silence compiler warnings.
1137 (md_assemble): Keep track of the instruction size. Allow white
1138 space between the $ and the constant for compatibility with older

3479 a29k .bss section; the mondfe program doesn't like it.

3500 source directory, if that's not the current directory.
3502 * configure.in (per-host): Accept MIPS host with BSD version

3528 avoid some redefinition complaints on some systems.
3529 (const, volatile): Don't need these conditionally defined if we
3530 use CONST and VOLATILE from ansidecl.h.
3531 (seg_name): Use CONST, not const.
3533 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3535 * config/tc-mips.c: Reindented to GNU standards.

3539 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3540 (fixup_segment): Add a29k special case; the linker is not prepared
3541 to see a segment offset here.
3543 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3546 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3548 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3549 srcdir, might be in objdir.

3568 * Makefile.in (targ-cpu.o): Depend on config.h.
3570 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3572 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3573 dropping a space immediately following an identifier.
3574 * expr.c, write.c: Rewrote assert expressions to not use multiple
3575 lines; I don't think that can be done portably.
3576 * config/tc-mips.c (macro): Use $AT if target register is zero in
3577 load instruction, which it can be for a floating point load.
3579 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3600 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3602 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3603 to be on a single line.
3605 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

3651 prototypes for all static functions. Moved existing minimal
3652 debugging format support info #ifndef OBJ_ECOFF blocks.

3701 * make-gas.com: Find obstack.obj if it's not in the current
3703 * read.c (s_ignore): Don't declare is_end_of_line. It's
3704 redundant, and triggers a VMS gcc compiler bug.
3706 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3707 current segment as an argument. (Ignored in all cases but VMS.)
3708 All callers and definitions changed.

4005 md_relax_table): Use default zero initialization.
4006 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4007 latter, instead of selecting with preprocessor conditionals.
4009 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4011 * configure.in: recognise all sparclite variants

4021 * expr.c (operand): If character other than comma or newline is a
4022 logical end-of-line character, use the newline case.
4023 From Eric Youngdale:
4024 (operand): Set X_add_number field for floating-point numbers.
4025 (operand): Treat zero byte as end-of-operand.
4027 * configure.in (per-target): Look for with_bfd_assembler option.
4028 For now, only accept "no", until the merge is done.
4030 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4031 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4037 * expr.c: Add "const" modifier to hex_value.
4038 * symbols.c: Finish conversion to S_* macros in the VMS only
4039 parts of the program. Add "const" modifier to
4040 md_[long,short]_jump_size. Remove declaration of const_flag
4041 (which will be declared in obj-vms.h).
4042 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4043 Fix arguments to VMS_write_object_file.
4044 * config-gas.com: New file. Script for VMS systems to set up the

4053 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4054 types of malformed stabs. Change parsing algorithm so that we are
4055 more certain of having all of the information that we need on hand.
4056 * obj-vms.c (final_forward_reference): New function, used to help
4057 resolve the data types of as many struct elements as possible
4058 when some part of the struct is not fully defined by the compiler.

4061 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4062 as symbols as well in the object file. Look for external functions

4065 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4067 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4068 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4069 have the name of the source file yet.

4072 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4074 * read.c (s_data): Always use "data_section", since it'll map to
4075 SEG_DATA or SEG_E1 if needed.
4076 (s_lcomm): Likewise with bss_section.
4077 (s_fill): Use memset, not bzero.
4079 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4104 mapping to segT enum values.
4105 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4106 if these are used or defined, if BFD_ASSEMBLER.
4107 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4108 subseg_new split into two functions.
4109 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4111 * as.h (volatile): Don't define if already defined.
4112 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4114 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4115 declare with format attribute for -Wformat checking.
4117 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4119 * app.c, config/tc-*.c: Don't include read.h, since it is already

4123 <mtranle@paris.intellicorp.com>.
4124 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4125 obj_format coffbfd and gas_target i386coff for target.

4127 * config/i386aix.mt: Removed (no longer used).
4128 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4130 (LDFLAGS): Added, defined as -shlib.
4131 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4132 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4133 (DOT_LABEL_PREFIX): Define.

4135 name rather than L0\001.
4136 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4138 * symbols.c, symbols.h (local_bss_counter): Removed.

4147 (size_section): Restored sanity check.
4148 (do_relocs_for): Base section address on s_paddr rather than
4149 computing it. Adjust a29k R_IHIHALF special case to account for
4150 section paddr (used to require paddr to be zero). If there are no
4151 reclos, set s_relptr to 0. Set relocation size in object_headers.
4152 (fill_section): Always set s_vaddr here, removing
4153 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4154 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4155 Set STYP_INFO for .comment.
4156 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4157 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4159 H_{SET,GET}_* macros.
4160 (do_linenos_for): Set lineno size in object_headers.
4161 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4162 set s_vaddr here. If string_byte_count remains 4, set it back to
4163 0, and only write strings out if there are some. Call
4164 fill_section before do_relocs_for and do_linenos_for.
4165 (obj_coff_section): Handle optional quoted second argument giving
4166 section characteristics.
4167 (obj_coff_bss): Added to handle .bss.
4168 (obj_coff_ident): Added to handle .ident (puts string in .comment

4188 (do_scrub_next_char): For \", return " not '.
4189 (symbol_chars): Now const.
4191 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4192 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4194 * config/obj-coff.h: Don't use #elif.
4196 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4197 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4199 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4201 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4223 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4224 using ZERO_BASED_SEGMENTS.
4225 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4226 never set segment address for SEG_E2 (.bss) and don't write out
4227 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4228 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4229 definitions, and don't merge tags with non-tags. Check for .bf
4230 rather than just checking whether the second character is b and
4231 the third character is f.
4232 (obj_coff_val): gcc can generate values which we don't handle
4233 correctly; discard information for now, since it only affects the
4234 debugging information.

4236 (yank_symbols): Don't merge labels.
4237 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4383 could be doing emulation.
4385 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4388 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4417 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4419 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4420 constant will not fit in an immediate field.
4421 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4456 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4458 * Support for i386-sysv.
4459 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4463 (fill_section): Don't set STYP_NOLOAD for .bss section.
4464 (fixup_segment): 386 uses strange common symbol format.

4497 * tc-z8k.c: lots of bug fixes
4499 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4501 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4502 #elif, since it is not supported by old compilers.
4503 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4504 couple of expressions in tc-m68k.c.
4506 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4508 * read.c (cons): If NO_RELOC is defined, use it.
4510 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4512 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4514 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4515 local labels to start with a .) and set REGISTER_PREFIX to %.
4516 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4518 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4532 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4534 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4535 sections starting from zero, rather than making them consecutive.
4536 This makes subsequent reloc calculations easier, esp if the object
4537 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4538 allocate lcomm in .data rather than in .bss. It seems that some
4539 tools can't cope with a non-zero sized bss before linkage.
4541 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4543 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4547 "-mno-688[58]1" options.
4549 * tc-m68k.c: Added CPU32 support.

4558 Change LIBDEPS dependence to LIBS.
4560 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4562 * Makefile.in (install): if $(tooldir) exists, install as in
4565 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4567 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4568 .word is < -32768 or > 32767. The -J flag causes the error to be
4569 ignored. This is to catch over-sized switches generated by gcc on
4570 systems which don't support the broken .word hack.
4571 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4572 write.c (fixup_segment): check for signed .word overflow if
4573 WARN_SIGNED_OVERFLOW_WORD.
4575 * write.c (fixup_segment): fixed missing parens in expression
4576 checking for byte or word overflow.
4578 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

4592 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4594 * input-scrub.c (input_scrub_push): call input_file_begin, not
4596 messages.c (as_perror): print ": " between the passed in error and
4597 the strerror, like perror does.

4602 From Steve Chamberlain:
4603 Makefile.in: Handle m68*-*-coff*.
4604 read.c, read.h: add mult argument to s_space
4606 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4607 Motorola and MIT syntax; gas can now assemble either type of
4609 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4615 (write_object_file) call fixup_mdeps
4616 (fixup_segment) set fx_subsy to 0.
4617 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4619 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4622 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4624 * Makefile.in (LIBS): Include opcode library.
4626 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

4646 tc-i960.c (md_ri_to_chars): Always output bout object file in
4647 little endian byte order (used to use endianness of host).
4649 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4651 * config/tc-m68k.c (init_table): Now const. Always include 68851
4652 data, so that "bc" is available to 68040 cache instructions.
4653 Added "tt0", "tt1", and 68ec030 variants.
4654 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4655 (enum _register): Added TT0, TT1.
4656 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4657 line number correctly in "internal error" messages. Don't print
4658 architecture-mismatch message for operand errors.
4660 From Colin Smith (colin@wrs.com):
4661 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4662 than install_operand.
4664 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4666 * listing.c (buffer_line): rewind to the start of include
4667 files, they might be included twice.
4669 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
4671 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)

4674 one element of a family.
4676 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
4678 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4679 so that we can assemble hand-written libgcc code.
4681 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4683 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4684 has already been formatted (but may still contain %-characters).
4687 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4689 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4690 written with indirection on the last two operands, which can be
4691 either data or address registers. Added a new operand type 'r'
4692 which accepts either register type. Added '(' to notend stuff in
4693 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4695 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
4697 * as.h (enum _relax_state): Start off at one, not zero, to better
4698 catch uninitialized-variable errors.

4706 data_last_frag): No longer static.
4707 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
4708 defined, call it. Change segments before calling fixup_segment.
4709 (relax_align): If linkrelax, provide extra padding.
4711 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4712 their not having symbols associated.
4714 * tc-i960.c (norelax, instrument_branches): Default initializer is
4716 (linkrelax): Delete variable definition.
4717 (mem_fmt): Call fix_new with NO_RELOC.

4805 characteristics have been), default to 68020. Don't need extra
4806 quotes around error string.

4888 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
4890 * write.c (write_object_file): keep the fix_tail clean, which
4891 fixes a bug in -R where relocations were being lost.
4893 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
4895 * configure.in: recognize m680x0 as having sun3 emulation mode for

4942 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4944 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4945 where gcc looks for it.
4947 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4949 * Makefile.in: Changed some lines to be less confusing for some

5019 * expr.c (operand): if can't work out what sort of operand it is,
5020 then look through FLT_CHARS for a hint.
5022 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5024 * Makefile.in, configure.in: removed traces of namesubdir,

5026 copyrights to '92, changed some from Cygnus to FSF.
5028 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5029 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5030 copyrights to '92, changed some from Cygnus to FSF.
5032 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5034 * expr.c: If an expression is single comma, then return with
5035 SEG_ABSENT rather than an error - since the sparc front end does
5036 really strange things with things like fbge,a
5038 * as.h: include bfd.h if using many sections
5039 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5040 local labels didn't work.
5041 * listing.c (list_symbol_table): don't core dump when there's no
5043 * write.c, write.h: call fix_new with the right number of args on
5045 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5048 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5050 * app.c: MRI compatibility - allow single quote to start a string.
5051 * as.c: fix typo recently introduced.
5052 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5053 * expr.c: Much rewriting, to accomodate MRI syntax for
5054 expressions. Also easier to read now.
5055 * listing.c: Put back defuns
5056 * read.c: modified to accept MRI syntax, put back listing pseudo
5057 ops so that an assembler built with NO_LISTING ignores list ops
5059 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5060 machine is a SPARC or a 29K.
5061 * config/obj-aout.c: added s_sect pseudo op
5062 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5063 fill in the timestamp.
5064 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5065 anymore, define all the relocs which the tc-<x> bit will use so we
5066 can translate from them to the coff types.
5067 * config/tc-a29k.c: reloc_type isn't ane enum any more
5068 * config/tc-m68k.c: Added NO_RELOC definition.
5070 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5072 * Makefile.in: put header files before C source for TAGS; remove
5073 references to non-existent syscalls.h.
5075 * read.c, write.c subsegs.c: back out the .bss changes.
5077 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5079 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5083 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5085 * symbols.c (local_label_name): symbols now start with ^A.
5087 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5088 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5089 generate these sections. .align: will use NOP_OPCODE or 0
5090 for padding. This is just for being nice to the
5093 * expr.c (operand): changed to generate local label "\001L0"
5094 starting with a ^A so that it is recognized as a local label.
5096 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5098 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5099 i/o opcodes - inb, inw, outb and outw. string manipulation with
5100 att syntax - scmp, slod, smov, ssca, ssto.
5102 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5103 to just after .file .
5105 In obj_crawl_symbol_chain() where it tries to put the external
5106 symbols apart, with the condition:
5107 (!S_IS_DEFINED(symbolP) &&
5108 !S_IS_DEBUG(symbolP) &&
5109 !SF_GET_STATICS(symbolP))
5110 it was moving too many symbols out. So I switch it back to the
5112 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5114 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5115 so that we don't use the F_RELFLG which make the linker complain
5116 that somebody has stripped the relocation info.
5118 Also, the AIX ld program require that the relocation table
5119 is sorted by r_vaddr like the standard ATT assembler does.
5121 [he also changed the sizeof(struct ...)'s into the coff
5122 style FOOSZ macros. I'm not sure this is right, but I can't
5123 remember why. xoxorich.]
5125 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5127 * Makefile.in, configure.in, doc: use the doc. Build it, install

5132 * read.c: white space and comments only.
5134 * configure.in: use the new atof-ns32.c for ns32k.
5136 * write.c: comment change only.
5138 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5139 aren't yet integrated.
5141 * tc-i860.[hc]: blew off the dust. Something must still be done
5142 about conflicting relocation types.
5144 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5147 * tc-i960.c, tc-sparc.c: white space and comments only.
5149 * tc-a29k.h: delete duplicate macro definition.
5151 * new file atof-ns32k.c copied from hack's last unreleased gas.
5153 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5155 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5158 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5159 ChangeLog's prior to this are sketchy at best. I have logs.
5160 They just aren't ChangeLogs.
