995 OPTIONAL_REGISTER_PREFIX if either is already defined.
997 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
999 * configure.in: Set bfd_gas for all sparc targets. Added facility
1000 for keeping or rejecting configurations still under development;
1001 default is to assume production environment, and reject configs
1002 still being worked on. Mark Elf configurations (except sparc and
1003 i386) as developmental. Deleted cases matching some generic names
1004 in favor of more specific names. (E.g., when we get Alpha
1005 support, we'll still only support VMS for Vax.)

1021 through inclusion of tc-hppa.h. Delete all forward declarations
1022 for functions only used within tc-hppa.c, likewise for structures,
1023 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1024 conditional code in a few small places.
1026 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1027 structures, global variables, forward declarations together.
1028 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
1029 conditional code -- try to group conditional code together
1030 into a few places. Make all functions and variables which
1031 are only used within tc-hppa.c static. PARAMize all functions.
1032 Add comments to functions. Delete unused functions, variables,
1033 #defines, etc. Delete unused members within structures. Delete
1034 ldil;ble hacks -- it is believed they were installed to work
1035 around old gas bugs. Avoid using mixed case for local
1036 functions, variables, and structures. Fix formatting problems
1037 not found by GNU-indent. Add FIXME notices for things which
1038 should be worked on the near future. Delete lots of old
1039 useless (1.36 PA-SOM) code.

1053 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
1054 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
1056 * config/tc-hppa.c: Likewise.
1058 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1059 of elf32_symbol_type.
1060 (pa_export_args): Likewise.
1061 (elf_hppa_final_processing): Likewise.
1062 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

1068 a multiple of the section alignment rather than always a
1071 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

1112 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1114 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1115 ELF, since the ELF object format does not have these type of
1116 relocations. Change the abort into as as_bad and return
1117 BFD_RELOC_NONE to silence compiler warnings.
1118 (md_assemble): Keep track of the instruction size. Allow white
1119 space between the $ and the constant for compatibility with older
1120 gases and other assemblers.

3457 dependencies are read, not when they are used).
3459 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
3460 a29k .bss section; the mondfe program doesn't like it.

3481 source directory, if that's not the current directory.
3483 * configure.in (per-host): Accept MIPS host with BSD version

3505 process relocs if there aren't any relocs to process. Avoids
3506 malloc/free bug on SCO too.

3509 avoid some redefinition complaints on some systems.
3510 (const, volatile): Don't need these conditionally defined if we
3511 use CONST and VOLATILE from ansidecl.h.
3512 (seg_name): Use CONST, not const.
3514 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3516 * config/tc-mips.c: Reindented to GNU standards.

3520 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3521 (fixup_segment): Add a29k special case; the linker is not prepared
3522 to see a segment offset here.
3524 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3527 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3529 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3530 srcdir, might be in objdir.
3532 * doc/Makefile.in: dvi depends on as.dvi

3545 bignums, but don't emit error message.
3547 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3549 * Makefile.in (targ-cpu.o): Depend on config.h.
3551 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3553 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3554 dropping a space immediately following an identifier.
3555 * expr.c, write.c: Rewrote assert expressions to not use multiple
3556 lines; I don't think that can be done portably.
3557 * config/tc-mips.c (macro): Use $AT if target register is zero in
3558 load instruction, which it can be for a floating point load.
3560 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3574 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
3577 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

3581 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3583 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3584 to be on a single line.

3631 * config/tc-mips.c: Rearranged for ECOFF support. Added
3632 prototypes for all static functions. Moved existing minimal
3633 debugging format support info #ifndef OBJ_ECOFF blocks.

3682 * make-gas.com: Find obstack.obj if it's not in the current
3684 * read.c (s_ignore): Don't declare is_end_of_line. It's
3685 redundant, and triggers a VMS gcc compiler bug.
3687 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3688 current segment as an argument. (Ignored in all cases but VMS.)
3689 All callers and definitions changed.

3707 argument to s_ignore. Put "#if 0" around unused code.
3708 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
3709 Call elf_xstabs for .stabs and .xstabs operators.

3986 md_relax_table): Use default zero initialization.
3987 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3988 latter, instead of selecting with preprocessor conditionals.
3990 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3992 * configure.in: recognise all sparclite variants

4002 * expr.c (operand): If character other than comma or newline is a
4003 logical end-of-line character, use the newline case.
4004 From Eric Youngdale:
4005 (operand): Set X_add_number field for floating-point numbers.
4006 (operand): Treat zero byte as end-of-operand.
4008 * configure.in (per-target): Look for with_bfd_assembler option.
4009 For now, only accept "no", until the merge is done.
4011 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4012 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4014 * read.c: Finish conversion to S_* macros in the VMS only
4015 parts of the program. Add "const" modifier to hex_value.
4016 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4018 * expr.c: Add "const" modifier to hex_value.
4019 * symbols.c: Finish conversion to S_* macros in the VMS only
4020 parts of the program. Add "const" modifier to
4021 md_[long,short]_jump_size. Remove declaration of const_flag
4022 (which will be declared in obj-vms.h).
4023 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4024 Fix arguments to VMS_write_object_file.
4025 * config-gas.com: New file. Script for VMS systems to set up the
4026 configuration to build gas for VMS, and create config.status.
4027 * make-gas.com: Redone to work with new scheme.
4028 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4030 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

4033 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4034 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4035 types of malformed stabs. Change parsing algorithm so that we are
4036 more certain of having all of the information that we need on hand.
4037 * obj-vms.c (final_forward_reference): New function, used to help
4038 resolve the data types of as many struct elements as possible
4039 when some part of the struct is not fully defined by the compiler.

4042 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4043 as symbols as well in the object file. Look for external functions
4044 that start with "__vt.", and turn them into variables, since the
4045 g++ compiler is incapable of doing this.
4046 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4048 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4049 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4050 have the name of the source file yet.
4051 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4053 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4055 * read.c (s_data): Always use "data_section", since it'll map to
4056 SEG_DATA or SEG_E1 if needed.
4057 (s_lcomm): Likewise with bss_section.
4058 (s_fill): Use memset, not bzero.
4060 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4081 (section_alignment): Declare only if not BFD_ASSEMBLER.
4082 (big_section, reg_section, pass1_section, diff_section,
4083 absent_section, text_section, data_section, bss_section): If
4084 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4085 mapping to segT enum values.
4086 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4087 if these are used or defined, if BFD_ASSEMBLER.
4088 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4089 subseg_new split into two functions.
4090 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4092 * as.h (volatile): Don't define if already defined.
4093 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4095 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4096 declare with format attribute for -Wformat checking.
4098 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4100 * app.c, config/tc-*.c: Don't include read.h, since it is already
4103 * These are based on patches from Minh Tran-le
4104 <mtranle@paris.intellicorp.com>.
4105 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4106 obj_format coffbfd and gas_target i386coff for target.
4107 (i[34]86-*-isc*): New host (uses sysv).
4108 * config/i386aix.mt: Removed (no longer used).
4109 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4111 (LDFLAGS): Added, defined as -shlib.
4112 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4113 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4114 (DOT_LABEL_PREFIX): Define.
4115 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4116 name rather than L0\001.
4117 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4119 * symbols.c, symbols.h (local_bss_counter): Removed.
4120 * write.c (write_object_file): bss no longer uses
4121 local_bss_counter. Pass correct data and bss size to
4122 VMS_write_object_file.

4128 (size_section): Restored sanity check.
4129 (do_relocs_for): Base section address on s_paddr rather than
4130 computing it. Adjust a29k R_IHIHALF special case to account for
4131 section paddr (used to require paddr to be zero). If there are no
4132 reclos, set s_relptr to 0. Set relocation size in object_headers.
4133 (fill_section): Always set s_vaddr here, removing
4134 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4135 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4136 Set STYP_INFO for .comment.
4137 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4138 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4140 H_{SET,GET}_* macros.
4141 (do_linenos_for): Set lineno size in object_headers.
4142 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4143 set s_vaddr here. If string_byte_count remains 4, set it back to
4144 0, and only write strings out if there are some. Call
4145 fill_section before do_relocs_for and do_linenos_for.
4146 (obj_coff_section): Handle optional quoted second argument giving
4147 section characteristics.
4148 (obj_coff_bss): Added to handle .bss.
4149 (obj_coff_ident): Added to handle .ident (puts string in .comment

4169 (do_scrub_next_char): For \", return " not '.
4170 (symbol_chars): Now const.
4172 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4173 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4175 * config/obj-coff.h: Don't use #elif.
4177 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4178 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4180 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4182 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4196 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
4198 * listing.c: Call xmalloc, not malloc; don't declare malloc.
4200 * Changes to support SCO 3.2v4:
4201 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
4202 SEG_BSS, fill with NOP_OPCODE.
4203 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4204 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4205 using ZERO_BASED_SEGMENTS.
4206 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4207 never set segment address for SEG_E2 (.bss) and don't write out
4208 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4209 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4210 definitions, and don't merge tags with non-tags. Check for .bf
4211 rather than just checking whether the second character is b and
4212 the third character is f.
4213 (obj_coff_val): gcc can generate values which we don't handle
4214 correctly; discard information for now, since it only affects the
4215 debugging information.
4216 (tag_find_or_name): Don't insert tags in the symbol table.
4217 (yank_symbols): Don't merge labels.
4218 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4364 could be doing emulation.
4366 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4369 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4398 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4400 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4401 constant will not fit in an immediate field.
4402 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4439 * Support for i386-sysv.
4440 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4478 * tc-z8k.c: lots of bug fixes
4480 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4482 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4483 #elif, since it is not supported by old compilers.
4484 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4485 couple of expressions in tc-m68k.c.
4487 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4489 * read.c (cons): If NO_RELOC is defined, use it.
4491 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4493 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4495 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4496 local labels to start with a .) and set REGISTER_PREFIX to %.
4497 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4499 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4513 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4515 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4516 sections starting from zero, rather than making them consecutive.
4517 This makes subsequent reloc calculations easier, esp if the object
4518 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4519 allocate lcomm in .data rather than in .bss. It seems that some
4520 tools can't cope with a non-zero sized bss before linkage.
4522 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4524 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4543 * Makefile.in (install): if $(tooldir) exists, install as in
4546 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4548 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4549 .word is < -32768 or > 32767. The -J flag causes the error to be
4550 ignored. This is to catch over-sized switches generated by gcc on
4551 systems which don't support the broken .word hack.
4552 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4553 write.c (fixup_segment): check for signed .word overflow if
4554 WARN_SIGNED_OVERFLOW_WORD.
4556 * write.c (fixup_segment): fixed missing parens in expression
4557 checking for byte or word overflow.
4559 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

4573 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4575 * input-scrub.c (input_scrub_push): call input_file_begin, not
4577 messages.c (as_perror): print ": " between the passed in error and
4578 the strerror, like perror does.

4583 From Steve Chamberlain:
4584 Makefile.in: Handle m68*-*-coff*.
4585 read.c, read.h: add mult argument to s_space
4587 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4588 Motorola and MIT syntax; gas can now assemble either type of

4597 (fixup_segment) set fx_subsy to 0.
4598 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4600 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4603 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4605 * Makefile.in (LIBS): Include opcode library.

4630 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4632 * config/tc-m68k.c (init_table): Now const. Always include 68851
4633 data, so that "bc" is available to 68040 cache instructions.
4634 Added "tt0", "tt1", and 68ec030 variants.
4635 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4636 (enum _register): Added TT0, TT1.
4637 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4638 line number correctly in "internal error" messages. Don't print
4639 architecture-mismatch message for operand errors.
4641 From Colin Smith (colin@wrs.com):
4642 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4643 than install_operand.

4647 * listing.c (buffer_line): rewind to the start of include
4648 files, they might be included twice.
4650 * z8k.c, z8k.h, z8k.mt: z8000 support stuff

4657 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
4659 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4660 so that we can assemble hand-written libgcc code.
4662 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4664 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4665 has already been formatted (but may still contain %-characters).
4668 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4670 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4671 written with indirection on the last two operands, which can be
4672 either data or address registers. Added a new operand type 'r'
4673 which accepts either register type. Added '(' to notend stuff in
4674 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4676 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
4678 * as.h (enum _relax_state): Start off at one, not zero, to better

4689 defined, call it. Change segments before calling fixup_segment.
4690 (relax_align): If linkrelax, provide extra padding.
4692 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4693 their not having symbols associated.
4695 * tc-i960.c (norelax, instrument_branches): Default initializer is
4697 (linkrelax): Delete variable definition.

4721 being used with args swapped, causing occasional lossage when
4722 refilling buffers after an include file.

4726 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
4727 version. Discard bogus DONTDEF version.

4785 (md_assemble): If no CPU has been set (even if FPU/PMMU
4786 characteristics have been), default to 68020. Don't need extra
4787 quotes around error string.

4869 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
4871 * write.c (write_object_file): keep the fix_tail clean, which
4872 fixes a bug in -R where relocations were being lost.
4874 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
4876 * configure.in: recognize m680x0 as having sun3 emulation mode for

4921 start addresses to match required alignment.
4923 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4925 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4926 where gcc looks for it.
4928 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4930 * Makefile.in: Changed some lines to be less confusing for some

4996 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4998 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5000 * expr.c (operand): if can't work out what sort of operand it is,
5001 then look through FLT_CHARS for a hint.
5003 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5005 * Makefile.in, configure.in: removed traces of namesubdir,
5006 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5007 copyrights to '92, changed some from Cygnus to FSF.
5009 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5010 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5011 copyrights to '92, changed some from Cygnus to FSF.
5013 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5015 * expr.c: If an expression is single comma, then return with
5016 SEG_ABSENT rather than an error - since the sparc front end does
5017 really strange things with things like fbge,a
5019 * as.h: include bfd.h if using many sections
5020 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5021 local labels didn't work.
5022 * listing.c (list_symbol_table): don't core dump when there's no
5024 * write.c, write.h: call fix_new with the right number of args on
5026 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5029 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5031 * app.c: MRI compatibility - allow single quote to start a string.
5032 * as.c: fix typo recently introduced.
5033 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5034 * expr.c: Much rewriting, to accomodate MRI syntax for
5035 expressions. Also easier to read now.
5036 * listing.c: Put back defuns
5037 * read.c: modified to accept MRI syntax, put back listing pseudo
5038 ops so that an assembler built with NO_LISTING ignores list ops
5040 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5041 machine is a SPARC or a 29K.
5042 * config/obj-aout.c: added s_sect pseudo op
5043 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5044 fill in the timestamp.
5045 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5046 anymore, define all the relocs which the tc-<x> bit will use so we
5047 can translate from them to the coff types.
5048 * config/tc-a29k.c: reloc_type isn't ane enum any more
5049 * config/tc-m68k.c: Added NO_RELOC definition.
5051 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5053 * Makefile.in: put header files before C source for TAGS; remove
5054 references to non-existent syscalls.h.
5056 * read.c, write.c subsegs.c: back out the .bss changes.
5058 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5060 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5064 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5066 * symbols.c (local_label_name): symbols now start with ^A.
5068 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5069 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5070 generate these sections. .align: will use NOP_OPCODE or 0
5071 for padding. This is just for being nice to the
5074 * expr.c (operand): changed to generate local label "\001L0"
5075 starting with a ^A so that it is recognized as a local label.
5077 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5079 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5080 i/o opcodes - inb, inw, outb and outw. string manipulation with
5081 att syntax - scmp, slod, smov, ssca, ssto.
5083 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5084 to just after .file .
5086 In obj_crawl_symbol_chain() where it tries to put the external
5087 symbols apart, with the condition:
5088 (!S_IS_DEFINED(symbolP) &&
5089 !S_IS_DEBUG(symbolP) &&
5090 !SF_GET_STATICS(symbolP))
5091 it was moving too many symbols out. So I switch it back to the
5093 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5095 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5096 so that we don't use the F_RELFLG which make the linker complain
5097 that somebody has stripped the relocation info.
5099 Also, the AIX ld program require that the relocation table
5100 is sorted by r_vaddr like the standard ATT assembler does.
5102 [he also changed the sizeof(struct ...)'s into the coff
5103 style FOOSZ macros. I'm not sure this is right, but I can't
5104 remember why. xoxorich.]
5106 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5108 * Makefile.in, configure.in, doc: use the doc. Build it, install
5111 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5113 * read.c: white space and comments only.
5115 * configure.in: use the new atof-ns32.c for ns32k.
5117 * write.c: comment change only.
5119 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5120 aren't yet integrated.
5122 * tc-i860.[hc]: blew off the dust. Something must still be done
5123 about conflicting relocation types.
5125 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5128 * tc-i960.c, tc-sparc.c: white space and comments only.
5130 * tc-a29k.h: delete duplicate macro definition.
5132 * new file atof-ns32k.c copied from hack's last unreleased gas.
5134 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5136 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5139 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5140 ChangeLog's prior to this are sketchy at best. I have logs.
5141 They just aren't ChangeLogs.
