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

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

552 conditional code -- try to group conditional code together
553 into a few places. Make all functions and variables which
554 are only used within tc-hppa.c static. PARAMize all functions.
555 Add comments to functions. Delete unused functions, variables,
556 #defines, etc. Delete unused members within structures. Delete
557 ldil;ble hacks -- it is believed they were installed to work
558 around old gas bugs. Avoid using mixed case for local
559 functions, variables, and structures. Fix formatting problems
560 not found by GNU-indent. Add FIXME notices for things which
561 should be worked on the near future. Delete lots of old
562 useless (1.36 PA-SOM) code.

577 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
579 * config/tc-hppa.c: Likewise.
581 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
582 of elf32_symbol_type.
583 (pa_export_args): Likewise.
584 (elf_hppa_final_processing): Likewise.
585 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed
587 (hppa_tc_make_sections): Do not declare elf_get_symtab_map any

591 a multiple of the section alignment rather than always a
594 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
595 bits are zero (eg they specify no relocations), then do not even
596 bother adding their entries to thesymextn section.

635 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
637 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
638 ELF, since the ELF object format does not have these type of
639 relocations. Change the abort into as as_bad and return
640 BFD_RELOC_NONE to silence compiler warnings.

2983 a29k .bss section; the mondfe program doesn't like it.

3004 source directory, if that's not the current directory.
3006 * configure.in (per-host): Accept MIPS host with BSD version

3032 avoid some redefinition complaints on some systems.
3033 (const, volatile): Don't need these conditionally defined if we
3034 use CONST and VOLATILE from ansidecl.h.
3035 (seg_name): Use CONST, not const.
3037 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3039 * config/tc-mips.c: Reindented to GNU standards.

3043 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3044 (fixup_segment): Add a29k special case; the linker is not prepared
3045 to see a segment offset here.
3047 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3050 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3052 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3053 srcdir, might be in objdir.

3068 bignums, but don't emit error message.
3070 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3072 * Makefile.in (targ-cpu.o): Depend on config.h.
3074 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3076 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3077 dropping a space immediately following an identifier.
3078 * expr.c, write.c: Rewrote assert expressions to not use multiple
3079 lines; I don't think that can be done portably.
3080 * config/tc-mips.c (macro): Use $AT if target register is zero in
3081 load instruction, which it can be for a floating point load.
3083 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3097 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
3100 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

3104 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3106 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3107 to be on a single line.
3109 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3111 * Makefile.in (config.h): Create file, writing out definitions of

3154 * config/tc-mips.c: Rearranged for ECOFF support. Added
3155 prototypes for all static functions. Moved existing minimal
3156 debugging format support info #ifndef OBJ_ECOFF blocks.

3205 * make-gas.com: Find obstack.obj if it's not in the current
3207 * read.c (s_ignore): Don't declare is_end_of_line. It's
3208 redundant, and triggers a VMS gcc compiler bug.
3210 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3211 current segment as an argument. (Ignored in all cases but VMS.)
3212 All callers and definitions changed.

3231 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
3232 Call elf_xstabs for .stabs and .xstabs operators.

3509 md_relax_table): Use default zero initialization.
3510 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3511 latter, instead of selecting with preprocessor conditionals.
3513 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3515 * configure.in: recognise all sparclite variants

3525 * expr.c (operand): If character other than comma or newline is a
3526 logical end-of-line character, use the newline case.
3527 From Eric Youngdale:
3528 (operand): Set X_add_number field for floating-point numbers.
3529 (operand): Treat zero byte as end-of-operand.
3531 * configure.in (per-target): Look for with_bfd_assembler option.
3532 For now, only accept "no", until the merge is done.
3534 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3535 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

3541 * expr.c: Add "const" modifier to hex_value.
3542 * symbols.c: Finish conversion to S_* macros in the VMS only
3543 parts of the program. Add "const" modifier to
3544 md_[long,short]_jump_size. Remove declaration of const_flag
3545 (which will be declared in obj-vms.h).
3546 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3547 Fix arguments to VMS_write_object_file.
3548 * config-gas.com: New file. Script for VMS systems to set up the
3549 configuration to build gas for VMS, and create config.status.
3550 * make-gas.com: Redone to work with new scheme.
3551 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

3556 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3557 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3558 types of malformed stabs. Change parsing algorithm so that we are
3559 more certain of having all of the information that we need on hand.
3560 * obj-vms.c (final_forward_reference): New function, used to help
3561 resolve the data types of as many struct elements as possible
3562 when some part of the struct is not fully defined by the compiler.

3565 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3566 as symbols as well in the object file. Look for external functions

3568 g++ compiler is incapable of doing this.
3569 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3571 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3572 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3573 have the name of the source file yet.
3574 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3576 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3578 * read.c (s_data): Always use "data_section", since it'll map to
3579 SEG_DATA or SEG_E1 if needed.
3580 (s_lcomm): Likewise with bss_section.
3581 (s_fill): Use memset, not bzero.
3583 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3605 (big_section, reg_section, pass1_section, diff_section,
3606 absent_section, text_section, data_section, bss_section): If
3607 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3608 mapping to segT enum values.
3609 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3610 if these are used or defined, if BFD_ASSEMBLER.
3611 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3612 subseg_new split into two functions.
3613 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3615 * as.h (volatile): Don't define if already defined.
3616 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3618 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3619 declare with format attribute for -Wformat checking.
3621 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3623 * app.c, config/tc-*.c: Don't include read.h, since it is already
3626 * These are based on patches from Minh Tran-le
3627 <mtranle@paris.intellicorp.com>.
3628 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3629 obj_format coffbfd and gas_target i386coff for target.
3630 (i[34]86-*-isc*): New host (uses sysv).
3631 * config/i386aix.mt: Removed (no longer used).
3632 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3634 (LDFLAGS): Added, defined as -shlib.
3635 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3636 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3637 (DOT_LABEL_PREFIX): Define.
3638 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3639 name rather than L0\001.
3640 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3642 * symbols.c, symbols.h (local_bss_counter): Removed.

3651 (size_section): Restored sanity check.
3652 (do_relocs_for): Base section address on s_paddr rather than
3653 computing it. Adjust a29k R_IHIHALF special case to account for
3654 section paddr (used to require paddr to be zero). If there are no
3655 reclos, set s_relptr to 0. Set relocation size in object_headers.
3656 (fill_section): Always set s_vaddr here, removing
3657 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3658 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3659 Set STYP_INFO for .comment.
3660 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
3661 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

3663 H_{SET,GET}_* macros.
3664 (do_linenos_for): Set lineno size in object_headers.
3665 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3666 set s_vaddr here. If string_byte_count remains 4, set it back to
3667 0, and only write strings out if there are some. Call
3668 fill_section before do_relocs_for and do_linenos_for.
3669 (obj_coff_section): Handle optional quoted second argument giving
3670 section characteristics.
3671 (obj_coff_bss): Added to handle .bss.
3672 (obj_coff_ident): Added to handle .ident (puts string in .comment

3692 (do_scrub_next_char): For \", return " not '.
3693 (symbol_chars): Now const.
3695 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3696 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3698 * config/obj-coff.h: Don't use #elif.
3700 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3701 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
3703 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
3705 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

3725 SEG_BSS, fill with NOP_OPCODE.
3726 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
3727 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
3728 using ZERO_BASED_SEGMENTS.
3729 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3730 never set segment address for SEG_E2 (.bss) and don't write out
3731 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3732 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3733 definitions, and don't merge tags with non-tags. Check for .bf
3734 rather than just checking whether the second character is b and
3735 the third character is f.
3736 (obj_coff_val): gcc can generate values which we don't handle
3737 correctly; discard information for now, since it only affects the
3738 debugging information.
3739 (tag_find_or_name): Don't insert tags in the symbol table.
3740 (yank_symbols): Don't merge labels.
3741 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3760 * config/tc-i386.c (md_pseudo_table): For 386bsd and linux, do
3761 power-of-two alignment for .align.
3763 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
3764 and leave everything else alone.

3887 could be doing emulation.
3889 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3892 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4005 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4006 #elif, since it is not supported by old compilers.
4007 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4008 couple of expressions in tc-m68k.c.
4010 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4012 * read.c (cons): If NO_RELOC is defined, use it.

4016 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4018 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4019 local labels to start with a .) and set REGISTER_PREFIX to %.
4020 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4036 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4038 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4039 sections starting from zero, rather than making them consecutive.
4040 This makes subsequent reloc calculations easier, esp if the object
4041 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4042 allocate lcomm in .data rather than in .bss. It seems that some
4043 tools can't cope with a non-zero sized bss before linkage.
4045 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4047 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4066 * Makefile.in (install): if $(tooldir) exists, install as in
4069 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4071 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4072 .word is < -32768 or > 32767. The -J flag causes the error to be
4073 ignored. This is to catch over-sized switches generated by gcc on
4074 systems which don't support the broken .word hack.
4075 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4076 write.c (fixup_segment): check for signed .word overflow if
4077 WARN_SIGNED_OVERFLOW_WORD.

4096 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4098 * input-scrub.c (input_scrub_push): call input_file_begin, not
4100 messages.c (as_perror): print ": " between the passed in error and
4101 the strerror, like perror does.

4106 From Steve Chamberlain:
4107 Makefile.in: Handle m68*-*-coff*.
4108 read.c, read.h: add mult argument to s_space
4110 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4111 Motorola and MIT syntax; gas can now assemble either type of

4121 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4123 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4126 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4128 * Makefile.in (LIBS): Include opcode library.

4153 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4155 * config/tc-m68k.c (init_table): Now const. Always include 68851
4156 data, so that "bc" is available to 68040 cache instructions.
4157 Added "tt0", "tt1", and 68ec030 variants.
4158 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4159 (enum _register): Added TT0, TT1.
4160 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4161 line number correctly in "internal error" messages. Don't print
4162 architecture-mismatch message for operand errors.
4164 From Colin Smith (colin@wrs.com):
4165 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

4182 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4183 so that we can assemble hand-written libgcc code.

4187 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4188 has already been formatted (but may still contain %-characters).
4191 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4193 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4194 written with indirection on the last two operands, which can be
4195 either data or address registers. Added a new operand type 'r'
4196 which accepts either register type. Added '(' to notend stuff in
4197 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4199 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

4215 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4216 their not having symbols associated.
4218 * tc-i960.c (norelax, instrument_branches): Default initializer is
4220 (linkrelax): Delete variable definition.

4244 being used with args swapped, causing occasional lossage when
4245 refilling buffers after an include file.

4249 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
4250 version. Discard bogus DONTDEF version.

4255 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
4256 selected architecture, print a message saying so and listing what

4309 characteristics have been), default to 68020. Don't need extra
4310 quotes around error string.

4392 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
4394 * write.c (write_object_file): keep the fix_tail clean, which
4395 fixes a bug in -R where relocations were being lost.
4397 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
4399 * configure.in: recognize m680x0 as having sun3 emulation mode for

4444 start addresses to match required alignment.
4446 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4448 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4449 where gcc looks for it.
4451 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4453 * Makefile.in: Changed some lines to be less confusing for some

4519 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4521 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4523 * expr.c (operand): if can't work out what sort of operand it is,
4524 then look through FLT_CHARS for a hint.
4526 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4528 * Makefile.in, configure.in: removed traces of namesubdir,
4529 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4530 copyrights to '92, changed some from Cygnus to FSF.
4532 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4533 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4534 copyrights to '92, changed some from Cygnus to FSF.
4536 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4538 * expr.c: If an expression is single comma, then return with
4539 SEG_ABSENT rather than an error - since the sparc front end does
4540 really strange things with things like fbge,a
4542 * as.h: include bfd.h if using many sections
4543 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4544 local labels didn't work.
4545 * listing.c (list_symbol_table): don't core dump when there's no
4547 * write.c, write.h: call fix_new with the right number of args on
4549 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4552 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4554 * app.c: MRI compatibility - allow single quote to start a string.
4555 * as.c: fix typo recently introduced.
4556 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4557 * expr.c: Much rewriting, to accomodate MRI syntax for
4558 expressions. Also easier to read now.
4559 * listing.c: Put back defuns
4560 * read.c: modified to accept MRI syntax, put back listing pseudo
4561 ops so that an assembler built with NO_LISTING ignores list ops
4563 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4564 machine is a SPARC or a 29K.
4565 * config/obj-aout.c: added s_sect pseudo op
4566 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4567 fill in the timestamp.
4568 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4569 anymore, define all the relocs which the tc-<x> bit will use so we
4570 can translate from them to the coff types.
4571 * config/tc-a29k.c: reloc_type isn't ane enum any more
4572 * config/tc-m68k.c: Added NO_RELOC definition.
4574 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4576 * Makefile.in: put header files before C source for TAGS; remove
4577 references to non-existent syscalls.h.
4579 * read.c, write.c subsegs.c: back out the .bss changes.
4581 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4583 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4587 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4589 * symbols.c (local_label_name): symbols now start with ^A.
4591 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4592 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4593 generate these sections. .align: will use NOP_OPCODE or 0
4594 for padding. This is just for being nice to the
4597 * expr.c (operand): changed to generate local label "\001L0"
4598 starting with a ^A so that it is recognized as a local label.
4600 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4602 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4603 i/o opcodes - inb, inw, outb and outw. string manipulation with
4604 att syntax - scmp, slod, smov, ssca, ssto.
4606 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4607 to just after .file .
4609 In obj_crawl_symbol_chain() where it tries to put the external
4610 symbols apart, with the condition:
4611 (!S_IS_DEFINED(symbolP) &&
4612 !S_IS_DEBUG(symbolP) &&
4613 !SF_GET_STATICS(symbolP))
4614 it was moving too many symbols out. So I switch it back to the
4616 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4618 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4619 so that we don't use the F_RELFLG which make the linker complain
4620 that somebody has stripped the relocation info.
4622 Also, the AIX ld program require that the relocation table
4623 is sorted by r_vaddr like the standard ATT assembler does.
4625 [he also changed the sizeof(struct ...)'s into the coff
4626 style FOOSZ macros. I'm not sure this is right, but I can't
4627 remember why. xoxorich.]
4629 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4631 * Makefile.in, configure.in, doc: use the doc. Build it, install

4636 * read.c: white space and comments only.
4638 * configure.in: use the new atof-ns32.c for ns32k.
4640 * write.c: comment change only.
4642 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4643 aren't yet integrated.
4645 * tc-i860.[hc]: blew off the dust. Something must still be done
4646 about conflicting relocation types.
4648 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4651 * tc-i960.c, tc-sparc.c: white space and comments only.
4653 * tc-a29k.h: delete duplicate macro definition.
4655 * new file atof-ns32k.c copied from hack's last unreleased gas.
4657 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4659 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4662 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4663 ChangeLog's prior to this are sketchy at best. I have logs.
4664 They just aren't ChangeLogs.
