487 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
488 applied are in range. Use bfd_put_32 rather than inserting each
489 byte of the fixed instrution into the buffer ourselves.
491 * write.c (fixup_segment): Delete {SEG,GLOBAL}_DIFF_ALLOWED code,
492 it was PA specific and is no longer needed (it's now handled

988 against placing additional object-file dependent code here. Warn
989 against contaminating all of GAS with the internals of tc-hppa.c
990 through inclusion of tc-hppa.h. Delete all forward declarations
991 for functions only used within tc-hppa.c, likewise for structures,
992 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
993 conditional code in a few small places.
995 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
996 structures, global variables, forward declarations together.

999 into a few places. Make all functions and variables which
1000 are only used within tc-hppa.c static. PARAMize all functions.
1001 Add comments to functions. Delete unused functions, variables,
1002 #defines, etc. Delete unused members within structures. Delete
1003 ldil;ble hacks -- it is believed they were installed to work
1004 around old gas bugs. Avoid using mixed case for local
1005 functions, variables, and structures. Fix formatting problems
1006 not found by GNU-indent. Add FIXME notices for things which
1007 should be worked on the near future. Delete lots of old
1008 useless (1.36 PA-SOM) code.

1037 a multiple of the section alignment rather than always a
1040 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2151 * Extensive changes to permit symbols to contain any expression
2152 type and to delay the computation of the expression until the
2153 value is actually needed. This permits setting symbols to values
2154 calculated based on object code size. Expressions were changed to
2155 no longer be in a section, to stop the overloading of segment and
2156 expression type that previously occurred.
2158 * as.c (big_section, pass1_section, diff_section, absent_section):
2160 (expr_section): Added (used for dummy symbols which hold

2246 to pop back to it. Handle unquoted section name as well as quoted
2247 section name. Don't crash on invalid strings.
2248 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

2269 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
2270 calculating opP->isiz; this permits the expression size to be
2271 determined as well, later on.
2273 * expr.c (clean_up_expression): Don't cancel the subtraction of
2276 * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R,

2285 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
2287 * read.c (float_cons): Simplified parsing logic. If
2288 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
2290 * symbols.c (colon): Rather than a special case for TC_HPPA,
2291 use new macro tc_frob_label.
2292 * config/tc-hppa.h (tc_frob_label): Define.
2294 * config/tc-mips.c: Many changes to support simple assembler

3450 source directory, if that's not the current directory.
3452 * configure.in (per-host): Accept MIPS host with BSD version

3478 avoid some redefinition complaints on some systems.
3479 (const, volatile): Don't need these conditionally defined if we
3480 use CONST and VOLATILE from ansidecl.h.
3481 (seg_name): Use CONST, not const.
3483 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3485 * config/tc-mips.c: Reindented to GNU standards.

3489 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3490 (fixup_segment): Add a29k special case; the linker is not prepared
3491 to see a segment offset here.

3496 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3498 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3499 srcdir, might be in objdir.

3518 * Makefile.in (targ-cpu.o): Depend on config.h.
3520 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3522 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3523 dropping a space immediately following an identifier.
3524 * expr.c, write.c: Rewrote assert expressions to not use multiple
3525 lines; I don't think that can be done portably.
3526 * config/tc-mips.c (macro): Use $AT if target register is zero in
3527 load instruction, which it can be for a floating point load.
3529 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3550 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3552 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3553 to be on a single line.

3601 prototypes for all static functions. Moved existing minimal
3602 debugging format support info #ifndef OBJ_ECOFF blocks.

3651 * make-gas.com: Find obstack.obj if it's not in the current
3653 * read.c (s_ignore): Don't declare is_end_of_line. It's
3654 redundant, and triggers a VMS gcc compiler bug.
3656 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3657 current segment as an argument. (Ignored in all cases but VMS.)
3658 All callers and definitions changed.

3955 md_relax_table): Use default zero initialization.
3956 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3957 latter, instead of selecting with preprocessor conditionals.
3959 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3961 * configure.in: recognise all sparclite variants

3971 * expr.c (operand): If character other than comma or newline is a
3972 logical end-of-line character, use the newline case.
3973 From Eric Youngdale:
3974 (operand): Set X_add_number field for floating-point numbers.
3975 (operand): Treat zero byte as end-of-operand.
3977 * configure.in (per-target): Look for with_bfd_assembler option.
3978 For now, only accept "no", until the merge is done.
3980 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3981 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

3987 * expr.c: Add "const" modifier to hex_value.
3988 * symbols.c: Finish conversion to S_* macros in the VMS only
3989 parts of the program. Add "const" modifier to
3990 md_[long,short]_jump_size. Remove declaration of const_flag
3991 (which will be declared in obj-vms.h).
3992 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3993 Fix arguments to VMS_write_object_file.
3994 * config-gas.com: New file. Script for VMS systems to set up the
3995 configuration to build gas for VMS, and create config.status.
3996 * make-gas.com: Redone to work with new scheme.
3997 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3999 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

4002 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4003 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4004 types of malformed stabs. Change parsing algorithm so that we are
4005 more certain of having all of the information that we need on hand.
4006 * obj-vms.c (final_forward_reference): New function, used to help
4007 resolve the data types of as many struct elements as possible
4008 when some part of the struct is not fully defined by the compiler.

4011 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4012 as symbols as well in the object file. Look for external functions

4014 g++ compiler is incapable of doing this.
4015 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4017 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4018 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4019 have the name of the source file yet.
4020 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4022 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4024 * read.c (s_data): Always use "data_section", since it'll map to
4025 SEG_DATA or SEG_E1 if needed.
4026 (s_lcomm): Likewise with bss_section.
4027 (s_fill): Use memset, not bzero.
4029 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4051 (big_section, reg_section, pass1_section, diff_section,
4052 absent_section, text_section, data_section, bss_section): If
4053 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4054 mapping to segT enum values.
4055 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4056 if these are used or defined, if BFD_ASSEMBLER.
4057 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4058 subseg_new split into two functions.
4059 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4061 * as.h (volatile): Don't define if already defined.
4062 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4064 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4065 declare with format attribute for -Wformat checking.
4067 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4069 * app.c, config/tc-*.c: Don't include read.h, since it is already
4072 * These are based on patches from Minh Tran-le
4073 <mtranle@paris.intellicorp.com>.
4074 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4075 obj_format coffbfd and gas_target i386coff for target.
4076 (i[34]86-*-isc*): New host (uses sysv).
4077 * config/i386aix.mt: Removed (no longer used).
4078 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4080 (LDFLAGS): Added, defined as -shlib.
4081 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4082 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4083 (DOT_LABEL_PREFIX): Define.
4084 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4085 name rather than L0\001.
4086 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4088 * symbols.c, symbols.h (local_bss_counter): Removed.

4097 (size_section): Restored sanity check.
4098 (do_relocs_for): Base section address on s_paddr rather than
4099 computing it. Adjust a29k R_IHIHALF special case to account for
4100 section paddr (used to require paddr to be zero). If there are no
4101 reclos, set s_relptr to 0. Set relocation size in object_headers.
4102 (fill_section): Always set s_vaddr here, removing
4103 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4104 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4105 Set STYP_INFO for .comment.
4106 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4107 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4109 H_{SET,GET}_* macros.
4110 (do_linenos_for): Set lineno size in object_headers.
4111 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4112 set s_vaddr here. If string_byte_count remains 4, set it back to
4113 0, and only write strings out if there are some. Call
4114 fill_section before do_relocs_for and do_linenos_for.
4115 (obj_coff_section): Handle optional quoted second argument giving
4116 section characteristics.
4117 (obj_coff_bss): Added to handle .bss.
4118 (obj_coff_ident): Added to handle .ident (puts string in .comment

4138 (do_scrub_next_char): For \", return " not '.
4139 (symbol_chars): Now const.
4141 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4142 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4144 * config/obj-coff.h: Don't use #elif.
4146 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4147 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4149 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4151 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4171 SEG_BSS, fill with NOP_OPCODE.
4172 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4173 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4174 using ZERO_BASED_SEGMENTS.
4175 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4176 never set segment address for SEG_E2 (.bss) and don't write out
4177 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4178 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4179 definitions, and don't merge tags with non-tags. Check for .bf
4180 rather than just checking whether the second character is b and
4181 the third character is f.
4182 (obj_coff_val): gcc can generate values which we don't handle
4183 correctly; discard information for now, since it only affects the
4184 debugging information.
4185 (tag_find_or_name): Don't insert tags in the symbol table.
4186 (yank_symbols): Don't merge labels.
4187 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4206 * config/tc-i386.c (md_pseudo_table): For 386bsd and linux, do
4207 power-of-two alignment for .align.
4209 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
4210 and leave everything else alone.

4333 could be doing emulation.
4335 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4338 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4369 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4370 constant will not fit in an immediate field.
4371 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4408 * Support for i386-sysv.
4409 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4451 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4452 #elif, since it is not supported by old compilers.
4453 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4454 couple of expressions in tc-m68k.c.
4456 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4458 * read.c (cons): If NO_RELOC is defined, use it.
4460 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4462 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4464 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4465 local labels to start with a .) and set REGISTER_PREFIX to %.
4466 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4482 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4484 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4485 sections starting from zero, rather than making them consecutive.
4486 This makes subsequent reloc calculations easier, esp if the object
4487 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4488 allocate lcomm in .data rather than in .bss. It seems that some
4489 tools can't cope with a non-zero sized bss before linkage.
4491 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4493 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4512 * Makefile.in (install): if $(tooldir) exists, install as in
4515 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4517 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4518 .word is < -32768 or > 32767. The -J flag causes the error to be
4519 ignored. This is to catch over-sized switches generated by gcc on
4520 systems which don't support the broken .word hack.
4521 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4522 write.c (fixup_segment): check for signed .word overflow if
4523 WARN_SIGNED_OVERFLOW_WORD.
4525 * write.c (fixup_segment): fixed missing parens in expression
4526 checking for byte or word overflow.

4542 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4544 * input-scrub.c (input_scrub_push): call input_file_begin, not
4546 messages.c (as_perror): print ": " between the passed in error and
4547 the strerror, like perror does.

4552 From Steve Chamberlain:
4553 Makefile.in: Handle m68*-*-coff*.
4554 read.c, read.h: add mult argument to s_space
4556 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4557 Motorola and MIT syntax; gas can now assemble either type of
4559 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4566 (fixup_segment) set fx_subsy to 0.
4567 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4569 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4572 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4574 * Makefile.in (LIBS): Include opcode library.
4576 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

4599 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4601 * config/tc-m68k.c (init_table): Now const. Always include 68851
4602 data, so that "bc" is available to 68040 cache instructions.
4603 Added "tt0", "tt1", and 68ec030 variants.
4604 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4605 (enum _register): Added TT0, TT1.
4606 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4607 line number correctly in "internal error" messages. Don't print
4608 architecture-mismatch message for operand errors.
4610 From Colin Smith (colin@wrs.com):
4611 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4612 than install_operand.

4628 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4629 so that we can assemble hand-written libgcc code.

4633 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4634 has already been formatted (but may still contain %-characters).
4637 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4639 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4640 written with indirection on the last two operands, which can be
4641 either data or address registers. Added a new operand type 'r'
4642 which accepts either register type. Added '(' to notend stuff in
4643 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4645 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

4661 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4662 their not having symbols associated.
4664 * tc-i960.c (norelax, instrument_branches): Default initializer is
4666 (linkrelax): Delete variable definition.

4701 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
4702 selected architecture, print a message saying so and listing what

4753 processor/opcode mismatch, so reword the error message.
4754 (md_assemble): If no CPU has been set (even if FPU/PMMU
4755 characteristics have been), default to 68020. Don't need extra
4756 quotes around error string.

4840 * write.c (write_object_file): keep the fix_tail clean, which
4841 fixes a bug in -R where relocations were being lost.
4843 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
4845 * configure.in: recognize m680x0 as having sun3 emulation mode for

4890 start addresses to match required alignment.
4892 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4894 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4895 where gcc looks for it.
4897 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4899 * Makefile.in: Changed some lines to be less confusing for some

4965 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4967 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4969 * expr.c (operand): if can't work out what sort of operand it is,
4970 then look through FLT_CHARS for a hint.
4972 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4974 * Makefile.in, configure.in: removed traces of namesubdir,
4975 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4976 copyrights to '92, changed some from Cygnus to FSF.
4978 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4979 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4980 copyrights to '92, changed some from Cygnus to FSF.
4982 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4984 * expr.c: If an expression is single comma, then return with
4985 SEG_ABSENT rather than an error - since the sparc front end does
4986 really strange things with things like fbge,a
4988 * as.h: include bfd.h if using many sections
4989 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4990 local labels didn't work.
4991 * listing.c (list_symbol_table): don't core dump when there's no
4993 * write.c, write.h: call fix_new with the right number of args on
4995 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4998 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5000 * app.c: MRI compatibility - allow single quote to start a string.
5001 * as.c: fix typo recently introduced.
5002 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5003 * expr.c: Much rewriting, to accomodate MRI syntax for
5004 expressions. Also easier to read now.
5005 * listing.c: Put back defuns
5006 * read.c: modified to accept MRI syntax, put back listing pseudo
5007 ops so that an assembler built with NO_LISTING ignores list ops
5009 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5010 machine is a SPARC or a 29K.
5011 * config/obj-aout.c: added s_sect pseudo op
5012 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5013 fill in the timestamp.
5014 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5015 anymore, define all the relocs which the tc-<x> bit will use so we
5016 can translate from them to the coff types.
5017 * config/tc-a29k.c: reloc_type isn't ane enum any more
5018 * config/tc-m68k.c: Added NO_RELOC definition.
5020 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5022 * Makefile.in: put header files before C source for TAGS; remove
5023 references to non-existent syscalls.h.
5025 * read.c, write.c subsegs.c: back out the .bss changes.
5027 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5029 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5033 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5035 * symbols.c (local_label_name): symbols now start with ^A.
5037 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5038 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5039 generate these sections. .align: will use NOP_OPCODE or 0
5040 for padding. This is just for being nice to the
5043 * expr.c (operand): changed to generate local label "\001L0"
5044 starting with a ^A so that it is recognized as a local label.
5046 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5048 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5049 i/o opcodes - inb, inw, outb and outw. string manipulation with
5050 att syntax - scmp, slod, smov, ssca, ssto.
5052 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5053 to just after .file .
5055 In obj_crawl_symbol_chain() where it tries to put the external
5056 symbols apart, with the condition:
5057 (!S_IS_DEFINED(symbolP) &&
5058 !S_IS_DEBUG(symbolP) &&
5059 !SF_GET_STATICS(symbolP))
5060 it was moving too many symbols out. So I switch it back to the
5062 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5064 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5065 so that we don't use the F_RELFLG which make the linker complain
5066 that somebody has stripped the relocation info.
5068 Also, the AIX ld program require that the relocation table
5069 is sorted by r_vaddr like the standard ATT assembler does.
5071 [he also changed the sizeof(struct ...)'s into the coff
5072 style FOOSZ macros. I'm not sure this is right, but I can't
5073 remember why. xoxorich.]
5075 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5077 * Makefile.in, configure.in, doc: use the doc. Build it, install

5082 * read.c: white space and comments only.
5084 * configure.in: use the new atof-ns32.c for ns32k.
5086 * write.c: comment change only.
5088 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5089 aren't yet integrated.
5091 * tc-i860.[hc]: blew off the dust. Something must still be done
5092 about conflicting relocation types.
5094 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5097 * tc-i960.c, tc-sparc.c: white space and comments only.
5099 * tc-a29k.h: delete duplicate macro definition.
5101 * new file atof-ns32k.c copied from hack's last unreleased gas.
5103 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5105 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5108 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5109 ChangeLog's prior to this are sketchy at best. I have logs.
5110 They just aren't ChangeLogs.
