988 * config/tc-m68k.h: Don't define REGISTER_PREFIX or
989 OPTIONAL_REGISTER_PREFIX if either is already defined.
991 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
993 * configure.in: Set bfd_gas for all sparc targets. Added facility
994 for keeping or rejecting configurations still under development;
995 default is to assume production environment, and reject configs
996 still being worked on. Mark Elf configurations (except sparc and
997 i386) as developmental. Deleted cases matching some generic names
998 in favor of more specific names. (E.g., when we get Alpha
999 support, we'll still only support VMS for Vax.)
1001 * config/tc-sparc.h (md_end): New macro.
1002 * config/tc-sparc.c (md_end): Function deleted.
1003 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

1013 against placing additional object-file dependent code here. Warn
1014 against contaminating all of GAS with the internals of tc-hppa.c
1015 through inclusion of tc-hppa.h. Delete all forward declarations
1016 for functions only used within tc-hppa.c, likewise for structures,
1017 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1018 conditional code in a few small places.
1020 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1021 structures, global variables, forward declarations together.
1022 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
1023 conditional code -- try to group conditional code together
1024 into a few places. Make all functions and variables which
1025 are only used within tc-hppa.c static. PARAMize all functions.
1026 Add comments to functions. Delete unused functions, variables,
1027 #defines, etc. Delete unused members within structures. Delete
1028 ldil;ble hacks -- it is believed they were installed to work
1029 around old gas bugs. Avoid using mixed case for local
1030 functions, variables, and structures. Fix formatting problems
1031 not found by GNU-indent. Add FIXME notices for things which
1032 should be worked on the near future. Delete lots of old
1033 useless (1.36 PA-SOM) code.

1045 which do not involve function symbols.
1047 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
1048 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
1050 * config/tc-hppa.c: Likewise.
1052 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1053 of elf32_symbol_type.
1054 (pa_export_args): Likewise.
1055 (elf_hppa_final_processing): Likewise.
1056 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

1061 * config/tc-hppa.c: (md_section_align): Align all sections to
1062 a multiple of the section alignment rather than always a
1065 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
1066 bits are zero (eg they specify no relocations), then do not even
1067 bother adding their entries to thesymextn section.

1106 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1108 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1109 ELF, since the ELF object format does not have these type of
1110 relocations. Change the abort into as as_bad and return
1111 BFD_RELOC_NONE to silence compiler warnings.
1112 (md_assemble): Keep track of the instruction size. Allow white
1113 space between the $ and the constant for compatibility with older
1114 gases and other assemblers.

3451 dependencies are read, not when they are used).
3453 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
3454 a29k .bss section; the mondfe program doesn't like it.

3475 source directory, if that's not the current directory.
3477 * configure.in (per-host): Accept MIPS host with BSD version

3503 avoid some redefinition complaints on some systems.
3504 (const, volatile): Don't need these conditionally defined if we
3505 use CONST and VOLATILE from ansidecl.h.
3506 (seg_name): Use CONST, not const.
3508 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3510 * config/tc-mips.c: Reindented to GNU standards.

3514 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3515 (fixup_segment): Add a29k special case; the linker is not prepared
3516 to see a segment offset here.
3518 * app.c (do_scrub_next_char): Added new state, 10, modifying state
3519 9 to only keep a space in between identifier characters.
3521 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3523 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3524 srcdir, might be in objdir.
3526 * doc/Makefile.in: dvi depends on as.dvi

3539 bignums, but don't emit error message.
3541 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3543 * Makefile.in (targ-cpu.o): Depend on config.h.
3545 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3547 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3548 dropping a space immediately following an identifier.
3549 * expr.c, write.c: Rewrote assert expressions to not use multiple
3550 lines; I don't think that can be done portably.
3551 * config/tc-mips.c (macro): Use $AT if target register is zero in
3552 load instruction, which it can be for a floating point load.
3554 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3568 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
3571 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

3575 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3577 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3578 to be on a single line.
3580 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

3625 * config/tc-mips.c: Rearranged for ECOFF support. Added
3626 prototypes for all static functions. Moved existing minimal
3627 debugging format support info #ifndef OBJ_ECOFF blocks.

3676 * make-gas.com: Find obstack.obj if it's not in the current
3678 * read.c (s_ignore): Don't declare is_end_of_line. It's
3679 redundant, and triggers a VMS gcc compiler bug.
3681 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3682 current segment as an argument. (Ignored in all cases but VMS.)
3683 All callers and definitions changed.

3701 argument to s_ignore. Put "#if 0" around unused code.
3702 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
3703 Call elf_xstabs for .stabs and .xstabs operators.

3980 md_relax_table): Use default zero initialization.
3981 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3982 latter, instead of selecting with preprocessor conditionals.
3984 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3986 * configure.in: recognise all sparclite variants

3996 * expr.c (operand): If character other than comma or newline is a
3997 logical end-of-line character, use the newline case.
3998 From Eric Youngdale:
3999 (operand): Set X_add_number field for floating-point numbers.
4000 (operand): Treat zero byte as end-of-operand.
4002 * configure.in (per-target): Look for with_bfd_assembler option.
4003 For now, only accept "no", until the merge is done.
4005 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4006 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4007 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4008 * read.c: Finish conversion to S_* macros in the VMS only
4009 parts of the program. Add "const" modifier to hex_value.
4010 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4012 * expr.c: Add "const" modifier to hex_value.
4013 * symbols.c: Finish conversion to S_* macros in the VMS only
4014 parts of the program. Add "const" modifier to
4015 md_[long,short]_jump_size. Remove declaration of const_flag
4016 (which will be declared in obj-vms.h).
4017 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4018 Fix arguments to VMS_write_object_file.
4019 * config-gas.com: New file. Script for VMS systems to set up the
4020 configuration to build gas for VMS, and create config.status.
4021 * make-gas.com: Redone to work with new scheme.
4022 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4024 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4025 will swap bytes if needed on a big endian system. Use throughout
4027 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4028 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4029 types of malformed stabs. Change parsing algorithm so that we are
4030 more certain of having all of the information that we need on hand.
4031 * obj-vms.c (final_forward_reference): New function, used to help
4032 resolve the data types of as many struct elements as possible
4033 when some part of the struct is not fully defined by the compiler.

4036 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4037 as symbols as well in the object file. Look for external functions
4038 that start with "__vt.", and turn them into variables, since the
4039 g++ compiler is incapable of doing this.
4040 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4042 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4043 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4044 have the name of the source file yet.
4045 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4047 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4049 * read.c (s_data): Always use "data_section", since it'll map to
4050 SEG_DATA or SEG_E1 if needed.
4051 (s_lcomm): Likewise with bss_section.
4052 (s_fill): Use memset, not bzero.
4054 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4075 (section_alignment): Declare only if not BFD_ASSEMBLER.
4076 (big_section, reg_section, pass1_section, diff_section,
4077 absent_section, text_section, data_section, bss_section): If
4078 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4079 mapping to segT enum values.
4080 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4081 if these are used or defined, if BFD_ASSEMBLER.
4082 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4083 subseg_new split into two functions.
4084 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4086 * as.h (volatile): Don't define if already defined.
4087 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4089 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4090 declare with format attribute for -Wformat checking.
4092 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4094 * app.c, config/tc-*.c: Don't include read.h, since it is already
4097 * These are based on patches from Minh Tran-le
4098 <mtranle@paris.intellicorp.com>.
4099 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4100 obj_format coffbfd and gas_target i386coff for target.
4101 (i[34]86-*-isc*): New host (uses sysv).
4102 * config/i386aix.mt: Removed (no longer used).
4103 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4105 (LDFLAGS): Added, defined as -shlib.
4106 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4107 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4108 (DOT_LABEL_PREFIX): Define.
4109 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4110 name rather than L0\001.
4111 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4113 * symbols.c, symbols.h (local_bss_counter): Removed.
4114 * write.c (write_object_file): bss no longer uses

4122 (size_section): Restored sanity check.
4123 (do_relocs_for): Base section address on s_paddr rather than
4124 computing it. Adjust a29k R_IHIHALF special case to account for
4125 section paddr (used to require paddr to be zero). If there are no
4126 reclos, set s_relptr to 0. Set relocation size in object_headers.
4127 (fill_section): Always set s_vaddr here, removing
4128 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4129 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4130 Set STYP_INFO for .comment.
4131 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4132 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4134 H_{SET,GET}_* macros.
4135 (do_linenos_for): Set lineno size in object_headers.
4136 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4137 set s_vaddr here. If string_byte_count remains 4, set it back to
4138 0, and only write strings out if there are some. Call
4139 fill_section before do_relocs_for and do_linenos_for.
4140 (obj_coff_section): Handle optional quoted second argument giving
4141 section characteristics.
4142 (obj_coff_bss): Added to handle .bss.
4143 (obj_coff_ident): Added to handle .ident (puts string in .comment

4163 (do_scrub_next_char): For \", return " not '.
4164 (symbol_chars): Now const.
4166 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4167 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4169 * config/obj-coff.h: Don't use #elif.
4171 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4172 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4174 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4176 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4190 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
4192 * listing.c: Call xmalloc, not malloc; don't declare malloc.
4194 * Changes to support SCO 3.2v4:
4195 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
4196 SEG_BSS, fill with NOP_OPCODE.
4197 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4198 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4199 using ZERO_BASED_SEGMENTS.
4200 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4201 never set segment address for SEG_E2 (.bss) and don't write out
4202 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4203 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4204 definitions, and don't merge tags with non-tags. Check for .bf
4205 rather than just checking whether the second character is b and
4206 the third character is f.
4207 (obj_coff_val): gcc can generate values which we don't handle
4208 correctly; discard information for now, since it only affects the
4209 debugging information.
4210 (tag_find_or_name): Don't insert tags in the symbol table.
4211 (yank_symbols): Don't merge labels.
4212 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4215 (obj_coff_section): Accept and ignore a trailing quoted string, as
4216 used in AT&T i386 syntax.
4217 (fixup_segment): Take segment as argument. On the i386, adjust PC
4218 relative addends by the segment vaddr.
4219 * tc-i386.h: Define SUB_SEGMENT_ALIGN.

4358 could be doing emulation.
4360 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4363 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4392 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4394 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4395 constant will not fit in an immediate field.
4396 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4431 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4433 * Support for i386-sysv.
4434 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4472 * tc-z8k.c: lots of bug fixes
4474 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4476 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4477 #elif, since it is not supported by old compilers.
4478 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4479 couple of expressions in tc-m68k.c.
4481 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4483 * read.c (cons): If NO_RELOC is defined, use it.
4485 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4487 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4489 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4490 local labels to start with a .) and set REGISTER_PREFIX to %.
4491 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4493 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4507 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4509 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4510 sections starting from zero, rather than making them consecutive.
4511 This makes subsequent reloc calculations easier, esp if the object
4512 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4513 allocate lcomm in .data rather than in .bss. It seems that some
4514 tools can't cope with a non-zero sized bss before linkage.
4516 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4518 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4537 * Makefile.in (install): if $(tooldir) exists, install as in
4540 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4542 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4543 .word is < -32768 or > 32767. The -J flag causes the error to be
4544 ignored. This is to catch over-sized switches generated by gcc on
4545 systems which don't support the broken .word hack.
4546 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4547 write.c (fixup_segment): check for signed .word overflow if
4548 WARN_SIGNED_OVERFLOW_WORD.
4550 * write.c (fixup_segment): fixed missing parens in expression
4551 checking for byte or word overflow.
4553 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

4567 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4569 * input-scrub.c (input_scrub_push): call input_file_begin, not
4571 messages.c (as_perror): print ": " between the passed in error and
4572 the strerror, like perror does.

4577 From Steve Chamberlain:
4578 Makefile.in: Handle m68*-*-coff*.
4579 read.c, read.h: add mult argument to s_space
4581 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4582 Motorola and MIT syntax; gas can now assemble either type of
4584 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4591 (fixup_segment) set fx_subsy to 0.
4592 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4594 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4597 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4599 * Makefile.in (LIBS): Include opcode library.
4601 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

4621 tc-i960.c (md_ri_to_chars): Always output bout object file in
4622 little endian byte order (used to use endianness of host).
4624 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4626 * config/tc-m68k.c (init_table): Now const. Always include 68851
4627 data, so that "bc" is available to 68040 cache instructions.
4628 Added "tt0", "tt1", and 68ec030 variants.
4629 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4630 (enum _register): Added TT0, TT1.
4631 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4632 line number correctly in "internal error" messages. Don't print
4633 architecture-mismatch message for operand errors.
4635 From Colin Smith (colin@wrs.com):
4636 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4637 than install_operand.

4641 * listing.c (buffer_line): rewind to the start of include
4642 files, they might be included twice.
4644 * z8k.c, z8k.h, z8k.mt: z8000 support stuff

4651 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
4653 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4654 so that we can assemble hand-written libgcc code.
4656 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4658 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4659 has already been formatted (but may still contain %-characters).
4662 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4664 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4665 written with indirection on the last two operands, which can be
4666 either data or address registers. Added a new operand type 'r'
4667 which accepts either register type. Added '(' to notend stuff in
4668 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4670 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
4672 * as.h (enum _relax_state): Start off at one, not zero, to better

4681 data_last_frag): No longer static.
4682 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
4683 defined, call it. Change segments before calling fixup_segment.
4684 (relax_align): If linkrelax, provide extra padding.
4686 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4687 their not having symbols associated.
4689 * tc-i960.c (norelax, instrument_branches): Default initializer is
4691 (linkrelax): Delete variable definition.
4692 (mem_fmt): Call fix_new with NO_RELOC.

4715 being used with args swapped, causing occasional lossage when
4716 refilling buffers after an include file.
4718 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
4720 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
4721 version. Discard bogus DONTDEF version.
4722 (as_warn, as_bad, as_fatal): Likewise.
4724 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
4726 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the

4779 (md_assemble): If no CPU has been set (even if FPU/PMMU
4780 characteristics have been), default to 68020. Don't need extra
4781 quotes around error string.

4863 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
4865 * write.c (write_object_file): keep the fix_tail clean, which
4866 fixes a bug in -R where relocations were being lost.
4868 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
4870 * configure.in: recognize m680x0 as having sun3 emulation mode for

4915 start addresses to match required alignment.
4917 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4919 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4920 where gcc looks for it.
4922 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4924 * Makefile.in: Changed some lines to be less confusing for some

4990 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4992 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4994 * expr.c (operand): if can't work out what sort of operand it is,
4995 then look through FLT_CHARS for a hint.
4997 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4999 * Makefile.in, configure.in: removed traces of namesubdir,
5000 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5001 copyrights to '92, changed some from Cygnus to FSF.
5003 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5004 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5005 copyrights to '92, changed some from Cygnus to FSF.
5007 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5009 * expr.c: If an expression is single comma, then return with
5010 SEG_ABSENT rather than an error - since the sparc front end does
5011 really strange things with things like fbge,a
5013 * as.h: include bfd.h if using many sections
5014 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5015 local labels didn't work.
5016 * listing.c (list_symbol_table): don't core dump when there's no
5018 * write.c, write.h: call fix_new with the right number of args on
5020 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5023 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5025 * app.c: MRI compatibility - allow single quote to start a string.
5026 * as.c: fix typo recently introduced.
5027 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5028 * expr.c: Much rewriting, to accomodate MRI syntax for
5029 expressions. Also easier to read now.
5030 * listing.c: Put back defuns
5031 * read.c: modified to accept MRI syntax, put back listing pseudo
5032 ops so that an assembler built with NO_LISTING ignores list ops
5034 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5035 machine is a SPARC or a 29K.
5036 * config/obj-aout.c: added s_sect pseudo op
5037 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5038 fill in the timestamp.
5039 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5040 anymore, define all the relocs which the tc-<x> bit will use so we
5041 can translate from them to the coff types.
5042 * config/tc-a29k.c: reloc_type isn't ane enum any more
5043 * config/tc-m68k.c: Added NO_RELOC definition.
5045 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5047 * Makefile.in: put header files before C source for TAGS; remove
5048 references to non-existent syscalls.h.
5050 * read.c, write.c subsegs.c: back out the .bss changes.
5052 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5054 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5058 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5060 * symbols.c (local_label_name): symbols now start with ^A.
5062 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5063 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5064 generate these sections. .align: will use NOP_OPCODE or 0
5065 for padding. This is just for being nice to the
5068 * expr.c (operand): changed to generate local label "\001L0"
5069 starting with a ^A so that it is recognized as a local label.
5071 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5073 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5074 i/o opcodes - inb, inw, outb and outw. string manipulation with
5075 att syntax - scmp, slod, smov, ssca, ssto.
5077 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5078 to just after .file .
5080 In obj_crawl_symbol_chain() where it tries to put the external
5081 symbols apart, with the condition:
5082 (!S_IS_DEFINED(symbolP) &&
5083 !S_IS_DEBUG(symbolP) &&
5084 !SF_GET_STATICS(symbolP))
5085 it was moving too many symbols out. So I switch it back to the
5087 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5089 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5090 so that we don't use the F_RELFLG which make the linker complain
5091 that somebody has stripped the relocation info.
5093 Also, the AIX ld program require that the relocation table
5094 is sorted by r_vaddr like the standard ATT assembler does.
5096 [he also changed the sizeof(struct ...)'s into the coff
5097 style FOOSZ macros. I'm not sure this is right, but I can't
5098 remember why. xoxorich.]
5100 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5102 * Makefile.in, configure.in, doc: use the doc. Build it, install
5105 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5107 * read.c: white space and comments only.
5109 * configure.in: use the new atof-ns32.c for ns32k.
5111 * write.c: comment change only.
5113 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5114 aren't yet integrated.
5116 * tc-i860.[hc]: blew off the dust. Something must still be done
5117 about conflicting relocation types.
5119 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5122 * tc-i960.c, tc-sparc.c: white space and comments only.
5124 * tc-a29k.h: delete duplicate macro definition.
5126 * new file atof-ns32k.c copied from hack's last unreleased gas.
5128 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5130 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5133 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5134 ChangeLog's prior to this are sketchy at best. I have logs.
5135 They just aren't ChangeLogs.
