1000 * config/tc-m68k.h: Don't define REGISTER_PREFIX or
1001 OPTIONAL_REGISTER_PREFIX if either is already defined.
1003 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
1005 * configure.in: Set bfd_gas for all sparc targets. Added facility
1006 for keeping or rejecting configurations still under development;
1007 default is to assume production environment, and reject configs
1008 still being worked on. Mark Elf configurations (except sparc and
1009 i386) as developmental. Deleted cases matching some generic names
1010 in favor of more specific names. (E.g., when we get Alpha
1011 support, we'll still only support VMS for Vax.)
1013 * config/tc-sparc.h (md_end): New macro.
1014 * config/tc-sparc.c (md_end): Function deleted.
1015 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

1025 against placing additional object-file dependent code here. Warn
1026 against contaminating all of GAS with the internals of tc-hppa.c
1027 through inclusion of tc-hppa.h. Delete all forward declarations
1028 for functions only used within tc-hppa.c, likewise for structures,
1029 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1030 conditional code in a few small places.
1032 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1033 structures, global variables, forward declarations together.
1034 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
1035 conditional code -- try to group conditional code together
1036 into a few places. Make all functions and variables which
1037 are only used within tc-hppa.c static. PARAMize all functions.
1038 Add comments to functions. Delete unused functions, variables,
1039 #defines, etc. Delete unused members within structures. Delete
1040 ldil;ble hacks -- it is believed they were installed to work
1041 around old gas bugs. Avoid using mixed case for local
1042 functions, variables, and structures. Fix formatting problems
1043 not found by GNU-indent. Add FIXME notices for things which
1044 should be worked on the near future. Delete lots of old
1045 useless (1.36 PA-SOM) code.

1057 which do not involve function symbols.
1059 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
1060 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
1062 * config/tc-hppa.c: Likewise.
1064 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1065 of elf32_symbol_type.
1066 (pa_export_args): Likewise.
1067 (elf_hppa_final_processing): Likewise.
1068 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

1073 * config/tc-hppa.c: (md_section_align): Align all sections to
1074 a multiple of the section alignment rather than always a
1077 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
1078 bits are zero (eg they specify no relocations), then do not even

1118 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1120 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1121 ELF, since the ELF object format does not have these type of
1122 relocations. Change the abort into as as_bad and return
1123 BFD_RELOC_NONE to silence compiler warnings.
1124 (md_assemble): Keep track of the instruction size. Allow white
1125 space between the $ and the constant for compatibility with older
1126 gases and other assemblers.

3465 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
3466 a29k .bss section; the mondfe program doesn't like it.

3487 source directory, if that's not the current directory.
3489 * configure.in (per-host): Accept MIPS host with BSD version

3511 process relocs if there aren't any relocs to process. Avoids
3512 malloc/free bug on SCO too.

3515 avoid some redefinition complaints on some systems.
3516 (const, volatile): Don't need these conditionally defined if we
3517 use CONST and VOLATILE from ansidecl.h.
3518 (seg_name): Use CONST, not const.
3520 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3522 * config/tc-mips.c: Reindented to GNU standards.

3526 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3527 (fixup_segment): Add a29k special case; the linker is not prepared
3528 to see a segment offset here.
3530 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3533 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3535 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3536 srcdir, might be in objdir.

3551 bignums, but don't emit error message.
3553 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3555 * Makefile.in (targ-cpu.o): Depend on config.h.
3557 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3559 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3560 dropping a space immediately following an identifier.
3561 * expr.c, write.c: Rewrote assert expressions to not use multiple
3562 lines; I don't think that can be done portably.
3563 * config/tc-mips.c (macro): Use $AT if target register is zero in
3564 load instruction, which it can be for a floating point load.
3566 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3587 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3589 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3590 to be on a single line.
3592 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

3638 prototypes for all static functions. Moved existing minimal
3639 debugging format support info #ifndef OBJ_ECOFF blocks.

3688 * make-gas.com: Find obstack.obj if it's not in the current
3690 * read.c (s_ignore): Don't declare is_end_of_line. It's
3691 redundant, and triggers a VMS gcc compiler bug.
3693 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3694 current segment as an argument. (Ignored in all cases but VMS.)
3695 All callers and definitions changed.

3713 argument to s_ignore. Put "#if 0" around unused code.
3714 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
3715 Call elf_xstabs for .stabs and .xstabs operators.
3717 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
3719 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are

3992 md_relax_table): Use default zero initialization.
3993 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3994 latter, instead of selecting with preprocessor conditionals.
3996 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3998 * configure.in: recognise all sparclite variants

4008 * expr.c (operand): If character other than comma or newline is a
4009 logical end-of-line character, use the newline case.
4010 From Eric Youngdale:
4011 (operand): Set X_add_number field for floating-point numbers.
4012 (operand): Treat zero byte as end-of-operand.
4014 * configure.in (per-target): Look for with_bfd_assembler option.
4015 For now, only accept "no", until the merge is done.
4017 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4018 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4024 * expr.c: Add "const" modifier to hex_value.
4025 * symbols.c: Finish conversion to S_* macros in the VMS only
4026 parts of the program. Add "const" modifier to
4027 md_[long,short]_jump_size. Remove declaration of const_flag
4028 (which will be declared in obj-vms.h).
4029 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4030 Fix arguments to VMS_write_object_file.
4031 * config-gas.com: New file. Script for VMS systems to set up the
4032 configuration to build gas for VMS, and create config.status.
4033 * make-gas.com: Redone to work with new scheme.
4034 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

4039 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4040 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4041 types of malformed stabs. Change parsing algorithm so that we are
4042 more certain of having all of the information that we need on hand.
4043 * obj-vms.c (final_forward_reference): New function, used to help
4044 resolve the data types of as many struct elements as possible
4045 when some part of the struct is not fully defined by the compiler.

4048 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4049 as symbols as well in the object file. Look for external functions

4051 g++ compiler is incapable of doing this.
4052 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4054 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4055 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4056 have the name of the source file yet.
4057 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4059 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4061 * read.c (s_data): Always use "data_section", since it'll map to
4062 SEG_DATA or SEG_E1 if needed.
4063 (s_lcomm): Likewise with bss_section.
4064 (s_fill): Use memset, not bzero.
4066 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4088 (big_section, reg_section, pass1_section, diff_section,
4089 absent_section, text_section, data_section, bss_section): If
4090 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4091 mapping to segT enum values.
4092 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4093 if these are used or defined, if BFD_ASSEMBLER.
4094 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4095 subseg_new split into two functions.
4096 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4098 * as.h (volatile): Don't define if already defined.
4099 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4101 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4102 declare with format attribute for -Wformat checking.
4104 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4106 * app.c, config/tc-*.c: Don't include read.h, since it is already
4109 * These are based on patches from Minh Tran-le
4110 <mtranle@paris.intellicorp.com>.
4111 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4112 obj_format coffbfd and gas_target i386coff for target.
4113 (i[34]86-*-isc*): New host (uses sysv).
4114 * config/i386aix.mt: Removed (no longer used).
4115 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4117 (LDFLAGS): Added, defined as -shlib.
4118 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4119 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4120 (DOT_LABEL_PREFIX): Define.
4121 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4122 name rather than L0\001.
4123 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4125 * symbols.c, symbols.h (local_bss_counter): Removed.

4134 (size_section): Restored sanity check.
4135 (do_relocs_for): Base section address on s_paddr rather than
4136 computing it. Adjust a29k R_IHIHALF special case to account for
4137 section paddr (used to require paddr to be zero). If there are no
4138 reclos, set s_relptr to 0. Set relocation size in object_headers.
4139 (fill_section): Always set s_vaddr here, removing
4140 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4141 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4142 Set STYP_INFO for .comment.
4143 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4144 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4146 H_{SET,GET}_* macros.
4147 (do_linenos_for): Set lineno size in object_headers.
4148 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4149 set s_vaddr here. If string_byte_count remains 4, set it back to
4150 0, and only write strings out if there are some. Call
4151 fill_section before do_relocs_for and do_linenos_for.
4152 (obj_coff_section): Handle optional quoted second argument giving
4153 section characteristics.
4154 (obj_coff_bss): Added to handle .bss.
4155 (obj_coff_ident): Added to handle .ident (puts string in .comment

4175 (do_scrub_next_char): For \", return " not '.
4176 (symbol_chars): Now const.
4178 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4179 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4181 * config/obj-coff.h: Don't use #elif.
4183 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4184 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4186 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4188 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4208 SEG_BSS, fill with NOP_OPCODE.
4209 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4210 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4211 using ZERO_BASED_SEGMENTS.
4212 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4213 never set segment address for SEG_E2 (.bss) and don't write out
4214 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4215 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4216 definitions, and don't merge tags with non-tags. Check for .bf
4217 rather than just checking whether the second character is b and
4218 the third character is f.
4219 (obj_coff_val): gcc can generate values which we don't handle
4220 correctly; discard information for now, since it only affects the
4221 debugging information.
4222 (tag_find_or_name): Don't insert tags in the symbol table.

4370 could be doing emulation.
4372 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4375 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4404 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4406 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4407 constant will not fit in an immediate field.
4408 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4443 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4445 * Support for i386-sysv.
4446 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4484 * tc-z8k.c: lots of bug fixes
4486 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4488 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4489 #elif, since it is not supported by old compilers.
4490 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4491 couple of expressions in tc-m68k.c.
4493 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4495 * read.c (cons): If NO_RELOC is defined, use it.
4497 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4499 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4501 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4502 local labels to start with a .) and set REGISTER_PREFIX to %.
4503 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4505 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4519 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4521 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4522 sections starting from zero, rather than making them consecutive.
4523 This makes subsequent reloc calculations easier, esp if the object
4524 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4525 allocate lcomm in .data rather than in .bss. It seems that some
4526 tools can't cope with a non-zero sized bss before linkage.
4528 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4530 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4534 "-mno-688[58]1" options.
4536 * tc-m68k.c: Added CPU32 support.

4547 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4549 * Makefile.in (install): if $(tooldir) exists, install as in
4552 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4554 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4555 .word is < -32768 or > 32767. The -J flag causes the error to be
4556 ignored. This is to catch over-sized switches generated by gcc on
4557 systems which don't support the broken .word hack.
4558 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4559 write.c (fixup_segment): check for signed .word overflow if
4560 WARN_SIGNED_OVERFLOW_WORD.
4562 * write.c (fixup_segment): fixed missing parens in expression
4563 checking for byte or word overflow.
4565 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

4579 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4581 * input-scrub.c (input_scrub_push): call input_file_begin, not
4583 messages.c (as_perror): print ": " between the passed in error and
4584 the strerror, like perror does.

4589 From Steve Chamberlain:
4590 Makefile.in: Handle m68*-*-coff*.
4591 read.c, read.h: add mult argument to s_space
4593 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4594 Motorola and MIT syntax; gas can now assemble either type of
4596 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4603 (fixup_segment) set fx_subsy to 0.
4604 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4606 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4609 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4611 * Makefile.in (LIBS): Include opcode library.
4613 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

4633 tc-i960.c (md_ri_to_chars): Always output bout object file in
4634 little endian byte order (used to use endianness of host).
4636 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4638 * config/tc-m68k.c (init_table): Now const. Always include 68851
4639 data, so that "bc" is available to 68040 cache instructions.
4640 Added "tt0", "tt1", and 68ec030 variants.
4641 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4642 (enum _register): Added TT0, TT1.
4643 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4644 line number correctly in "internal error" messages. Don't print
4645 architecture-mismatch message for operand errors.
4647 From Colin Smith (colin@wrs.com):
4648 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4649 than install_operand.
4651 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4653 * listing.c (buffer_line): rewind to the start of include
4654 files, they might be included twice.
4656 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
4658 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)

4661 one element of a family.
4663 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
4665 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4666 so that we can assemble hand-written libgcc code.
4668 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4670 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4671 has already been formatted (but may still contain %-characters).
4674 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4676 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4677 written with indirection on the last two operands, which can be
4678 either data or address registers. Added a new operand type 'r'
4679 which accepts either register type. Added '(' to notend stuff in
4680 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4682 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
4684 * as.h (enum _relax_state): Start off at one, not zero, to better
4685 catch uninitialized-variable errors.

4693 data_last_frag): No longer static.
4694 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
4695 defined, call it. Change segments before calling fixup_segment.
4696 (relax_align): If linkrelax, provide extra padding.
4698 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4699 their not having symbols associated.
4701 * tc-i960.c (norelax, instrument_branches): Default initializer is
4703 (linkrelax): Delete variable definition.
4704 (mem_fmt): Call fix_new with NO_RELOC.

4792 characteristics have been), default to 68020. Don't need extra
4793 quotes around error string.

4877 * write.c (write_object_file): keep the fix_tail clean, which
4878 fixes a bug in -R where relocations were being lost.
4880 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
4882 * configure.in: recognize m680x0 as having sun3 emulation mode for

4929 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4931 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4932 where gcc looks for it.
4934 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4936 * Makefile.in: Changed some lines to be less confusing for some

5002 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5004 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5006 * expr.c (operand): if can't work out what sort of operand it is,
5007 then look through FLT_CHARS for a hint.
5009 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5011 * Makefile.in, configure.in: removed traces of namesubdir,
5012 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5013 copyrights to '92, changed some from Cygnus to FSF.
5015 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5016 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5017 copyrights to '92, changed some from Cygnus to FSF.
5019 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5021 * expr.c: If an expression is single comma, then return with
5022 SEG_ABSENT rather than an error - since the sparc front end does
5023 really strange things with things like fbge,a
5025 * as.h: include bfd.h if using many sections
5026 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5027 local labels didn't work.
5028 * listing.c (list_symbol_table): don't core dump when there's no
5030 * write.c, write.h: call fix_new with the right number of args on
5032 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5035 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5037 * app.c: MRI compatibility - allow single quote to start a string.
5038 * as.c: fix typo recently introduced.
5039 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5040 * expr.c: Much rewriting, to accomodate MRI syntax for
5041 expressions. Also easier to read now.
5042 * listing.c: Put back defuns
5043 * read.c: modified to accept MRI syntax, put back listing pseudo
5044 ops so that an assembler built with NO_LISTING ignores list ops
5046 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5047 machine is a SPARC or a 29K.
5048 * config/obj-aout.c: added s_sect pseudo op
5049 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5050 fill in the timestamp.
5051 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5052 anymore, define all the relocs which the tc-<x> bit will use so we
5053 can translate from them to the coff types.
5054 * config/tc-a29k.c: reloc_type isn't ane enum any more
5055 * config/tc-m68k.c: Added NO_RELOC definition.
5057 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5059 * Makefile.in: put header files before C source for TAGS; remove
5060 references to non-existent syscalls.h.
5062 * read.c, write.c subsegs.c: back out the .bss changes.
5064 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5066 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5070 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5072 * symbols.c (local_label_name): symbols now start with ^A.
5074 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5075 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5076 generate these sections. .align: will use NOP_OPCODE or 0
5077 for padding. This is just for being nice to the
5080 * expr.c (operand): changed to generate local label "\001L0"
5081 starting with a ^A so that it is recognized as a local label.
5083 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5085 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5086 i/o opcodes - inb, inw, outb and outw. string manipulation with
5087 att syntax - scmp, slod, smov, ssca, ssto.
5089 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5090 to just after .file .
5092 In obj_crawl_symbol_chain() where it tries to put the external
5093 symbols apart, with the condition:
5094 (!S_IS_DEFINED(symbolP) &&
5095 !S_IS_DEBUG(symbolP) &&
5096 !SF_GET_STATICS(symbolP))
5097 it was moving too many symbols out. So I switch it back to the
5099 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5101 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5102 so that we don't use the F_RELFLG which make the linker complain
5103 that somebody has stripped the relocation info.
5105 Also, the AIX ld program require that the relocation table
5106 is sorted by r_vaddr like the standard ATT assembler does.
5108 [he also changed the sizeof(struct ...)'s into the coff
5109 style FOOSZ macros. I'm not sure this is right, but I can't
5110 remember why. xoxorich.]
5112 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5114 * Makefile.in, configure.in, doc: use the doc. Build it, install
5117 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5119 * read.c: white space and comments only.
5121 * configure.in: use the new atof-ns32.c for ns32k.
5123 * write.c: comment change only.
5125 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5126 aren't yet integrated.
5128 * tc-i860.[hc]: blew off the dust. Something must still be done
5129 about conflicting relocation types.
5131 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5134 * tc-i960.c, tc-sparc.c: white space and comments only.
5136 * tc-a29k.h: delete duplicate macro definition.
5138 * new file atof-ns32k.c copied from hack's last unreleased gas.
5140 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5142 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5145 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5146 ChangeLog's prior to this are sketchy at best. I have logs.
5147 They just aren't ChangeLogs.
