1888 i386) as developmental. Deleted cases matching some generic names
1889 in favor of more specific names. (E.g., when we get Alpha

3067 * Extensive changes to permit symbols to contain any expression
3068 type and to delay the computation of the expression until the
3069 value is actually needed. This permits setting symbols to values
3070 calculated based on object code size. Expressions were changed to
3071 no longer be in a section, to stop the overloading of segment and
3072 expression type that previously occurred.
3074 * as.c (big_section, pass1_section, diff_section, absent_section):
3076 (expr_section): Added (used for dummy symbols which hold

3162 to pop back to it. Handle unquoted section name as well as quoted
3163 section name. Don't crash on invalid strings.

3185 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
3186 calculating opP->isiz; this permits the expression size to be
3187 determined as well, later on.

3201 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
3203 * read.c (float_cons): Simplified parsing logic. If
3204 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

3207 use new macro tc_frob_label.
3208 * config/tc-hppa.h (tc_frob_label): Define.

3247 * config/obj-coffbfd.c (fixup_segment): If TC_M88K, don't adjust
3248 by md_pcrel_from if we are relocating against a symbol (we still
3249 need md_pcrel_from for a PC relative relocation within the same

4342 dependencies are read, not when they are used).
4344 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4345 a29k .bss section; the mondfe program doesn't like it.

4394 avoid some redefinition complaints on some systems.
4395 (const, volatile): Don't need these conditionally defined if we
4396 use CONST and VOLATILE from ansidecl.h.
4397 (seg_name): Use CONST, not const.
4399 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4401 * config/tc-mips.c: Reindented to GNU standards.

4412 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4414 * Makefile.in: add dvi target; as-$(config).texinfo might live in

4434 * Makefile.in (targ-cpu.o): Depend on config.h.
4436 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4438 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4439 dropping a space immediately following an identifier.
4440 * expr.c, write.c: Rewrote assert expressions to not use multiple
4441 lines; I don't think that can be done portably.
4442 * config/tc-mips.c (macro): Use $AT if target register is zero in
4443 load instruction, which it can be for a floating point load.
4445 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4466 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4468 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4469 to be on a single line.

4517 prototypes for all static functions. Moved existing minimal
4518 debugging format support info #ifndef OBJ_ECOFF blocks.

4521 all callers accordingly.
4522 (tc_get_register): Renamed from get_register, and made non-static.
4524 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4567 * make-gas.com: Find obstack.obj if it's not in the current
4569 * read.c (s_ignore): Don't declare is_end_of_line. It's
4570 redundant, and triggers a VMS gcc compiler bug.
4572 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4573 current segment as an argument. (Ignored in all cases but VMS.)
4574 All callers and definitions changed.

4705 for now; should be machine-dependent.
4707 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
4708 targets, forcing BFD use.

4871 md_relax_table): Use default zero initialization.
4872 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4873 latter, instead of selecting with preprocessor conditionals.
4875 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4877 * configure.in: recognise all sparclite variants

4887 * expr.c (operand): If character other than comma or newline is a
4888 logical end-of-line character, use the newline case.
4889 From Eric Youngdale:
4890 (operand): Set X_add_number field for floating-point numbers.
4891 (operand): Treat zero byte as end-of-operand.
4893 * configure.in (per-target): Look for with_bfd_assembler option.
4894 For now, only accept "no", until the merge is done.
4896 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4897 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4899 * read.c: Finish conversion to S_* macros in the VMS only
4900 parts of the program. Add "const" modifier to hex_value.
4901 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4903 * expr.c: Add "const" modifier to hex_value.
4904 * symbols.c: Finish conversion to S_* macros in the VMS only
4905 parts of the program. Add "const" modifier to
4906 md_[long,short]_jump_size. Remove declaration of const_flag
4907 (which will be declared in obj-vms.h).
4908 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4909 Fix arguments to VMS_write_object_file.
4910 * config-gas.com: New file. Script for VMS systems to set up the
4911 configuration to build gas for VMS, and create config.status.
4912 * make-gas.com: Redone to work with new scheme.
4913 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4915 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4916 will swap bytes if needed on a big endian system. Use throughout
4918 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4919 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4920 types of malformed stabs. Change parsing algorithm so that we are
4921 more certain of having all of the information that we need on hand.
4922 * obj-vms.c (final_forward_reference): New function, used to help
4923 resolve the data types of as many struct elements as possible
4924 when some part of the struct is not fully defined by the compiler.

4927 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4928 as symbols as well in the object file. Look for external functions
4929 that start with "__vt.", and turn them into variables, since the
4930 g++ compiler is incapable of doing this.
4931 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4933 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4934 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4935 have the name of the source file yet.
4936 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4938 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4940 * read.c (s_data): Always use "data_section", since it'll map to
4941 SEG_DATA or SEG_E1 if needed.
4942 (s_lcomm): Likewise with bss_section.
4943 (s_fill): Use memset, not bzero.
4945 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4967 (big_section, reg_section, pass1_section, diff_section,
4968 absent_section, text_section, data_section, bss_section): If
4969 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4970 mapping to segT enum values.
4971 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4972 if these are used or defined, if BFD_ASSEMBLER.
4973 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4974 subseg_new split into two functions.
4975 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4977 * as.h (volatile): Don't define if already defined.
4978 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4980 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4981 declare with format attribute for -Wformat checking.
4983 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4985 * app.c, config/tc-*.c: Don't include read.h, since it is already
4988 * These are based on patches from Minh Tran-le
4989 <mtranle@paris.intellicorp.com>.
4990 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4991 obj_format coffbfd and gas_target i386coff for target.
4992 (i[34]86-*-isc*): New host (uses sysv).
4993 * config/i386aix.mt: Removed (no longer used).
4994 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4996 (LDFLAGS): Added, defined as -shlib.
4997 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4998 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4999 (DOT_LABEL_PREFIX): Define.
5000 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5001 name rather than L0\001.
5002 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5004 * symbols.c, symbols.h (local_bss_counter): Removed.
5005 * write.c (write_object_file): bss no longer uses

5013 (size_section): Restored sanity check.
5014 (do_relocs_for): Base section address on s_paddr rather than
5015 computing it. Adjust a29k R_IHIHALF special case to account for
5016 section paddr (used to require paddr to be zero). If there are no
5017 reclos, set s_relptr to 0. Set relocation size in object_headers.
5018 (fill_section): Always set s_vaddr here, removing
5019 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5020 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5021 Set STYP_INFO for .comment.
5022 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5023 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5025 H_{SET,GET}_* macros.
5026 (do_linenos_for): Set lineno size in object_headers.
5027 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5028 set s_vaddr here. If string_byte_count remains 4, set it back to
5029 0, and only write strings out if there are some. Call
5030 fill_section before do_relocs_for and do_linenos_for.
5031 (obj_coff_section): Handle optional quoted second argument giving
5032 section characteristics.
5033 (obj_coff_bss): Added to handle .bss.
5034 (obj_coff_ident): Added to handle .ident (puts string in .comment

5054 (do_scrub_next_char): For \", return " not '.
5055 (symbol_chars): Now const.
5057 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5058 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5060 * config/obj-coff.h: Don't use #elif.
5062 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5063 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5065 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5067 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5087 SEG_BSS, fill with NOP_OPCODE.
5088 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5089 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5090 using ZERO_BASED_SEGMENTS.
5091 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5092 never set segment address for SEG_E2 (.bss) and don't write out
5093 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5094 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5095 definitions, and don't merge tags with non-tags. Check for .bf
5096 rather than just checking whether the second character is b and
5097 the third character is f.
5098 (obj_coff_val): gcc can generate values which we don't handle
5099 correctly; discard information for now, since it only affects the
5100 debugging information.
5101 (tag_find_or_name): Don't insert tags in the symbol table.
5102 (yank_symbols): Don't merge labels.
5103 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5123 power-of-two alignment for .align.
5125 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
5126 and leave everything else alone.

5158 options. Updated options documentation for m68k. Some minor
5159 wording/punctuation changes.
5161 Mon Nov 30 11:42:11 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5163 * configure.in: Accept target OS "vms".
5165 * symbols.c: Merged ANSI and non-ANSI function decls, using

5215 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
5217 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
5220 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
5222 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

5249 could be doing emulation.
5251 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5254 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5283 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5285 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5286 constant will not fit in an immediate field.
5287 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5322 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5324 * Support for i386-sysv.
5325 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5365 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5367 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5368 #elif, since it is not supported by old compilers.
5369 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5370 couple of expressions in tc-m68k.c.
5372 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5374 * read.c (cons): If NO_RELOC is defined, use it.
5376 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5378 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5380 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5381 local labels to start with a .) and set REGISTER_PREFIX to %.
5382 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5384 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5398 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5400 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5401 sections starting from zero, rather than making them consecutive.
5402 This makes subsequent reloc calculations easier, esp if the object
5403 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5404 allocate lcomm in .data rather than in .bss. It seems that some
5405 tools can't cope with a non-zero sized bss before linkage.
5407 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5409 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5426 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
5428 * Makefile.in (install): if $(tooldir) exists, install as in
5431 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5433 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5434 .word is < -32768 or > 32767. The -J flag causes the error to be
5435 ignored. This is to catch over-sized switches generated by gcc on
5436 systems which don't support the broken .word hack.
5437 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5438 write.c (fixup_segment): check for signed .word overflow if
5439 WARN_SIGNED_OVERFLOW_WORD.
5441 * write.c (fixup_segment): fixed missing parens in expression
5442 checking for byte or word overflow.
5444 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

5458 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5460 * input-scrub.c (input_scrub_push): call input_file_begin, not
5462 messages.c (as_perror): print ": " between the passed in error and
5463 the strerror, like perror does.
5465 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
5467 * Makefile.in: use gas_target instead of modifying target_cpu.
5468 From Steve Chamberlain:
5469 Makefile.in: Handle m68*-*-coff*.
5470 read.c, read.h: add mult argument to s_space
5472 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5473 Motorola and MIT syntax; gas can now assemble either type of
5475 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5481 (write_object_file) call fixup_mdeps
5482 (fixup_segment) set fx_subsy to 0.
5483 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5485 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5488 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5490 * Makefile.in (LIBS): Include opcode library.
5492 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5512 tc-i960.c (md_ri_to_chars): Always output bout object file in
5513 little endian byte order (used to use endianness of host).
5515 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5517 * config/tc-m68k.c (init_table): Now const. Always include 68851
5518 data, so that "bc" is available to 68040 cache instructions.
5519 Added "tt0", "tt1", and 68ec030 variants.
5520 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5521 (enum _register): Added TT0, TT1.
5522 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5523 line number correctly in "internal error" messages. Don't print
5524 architecture-mismatch message for operand errors.
5526 From Colin Smith (colin@wrs.com):
5527 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5528 than install_operand.

5532 * listing.c (buffer_line): rewind to the start of include
5533 files, they might be included twice.

5542 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5544 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5545 so that we can assemble hand-written libgcc code.
5547 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5549 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5550 has already been formatted (but may still contain %-characters).
5553 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5555 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5556 written with indirection on the last two operands, which can be
5557 either data or address registers. Added a new operand type 'r'
5558 which accepts either register type. Added '(' to notend stuff in
5559 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5561 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
5563 * as.h (enum _relax_state): Start off at one, not zero, to better

5574 defined, call it. Change segments before calling fixup_segment.
5575 (relax_align): If linkrelax, provide extra padding.
5577 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5578 their not having symbols associated.
5580 * tc-i960.c (norelax, instrument_branches): Default initializer is
5582 (linkrelax): Delete variable definition.

5605 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
5606 being used with args swapped, causing occasional lossage when
5607 refilling buffers after an include file.
5609 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5611 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
5612 version. Discard bogus DONTDEF version.
5613 (as_warn, as_bad, as_fatal): Likewise.
5615 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
5617 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5618 selected architecture, print a message saying so and listing what
5619 processors support it, rather than saying "operands mismatch".

5648 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
5649 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

5659 fx_offset into account.
5661 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
5663 * configure.in (mips host): Accept "ultrix" with version number.
5665 * expr.c (floating_constant): Separate "=-" to avoid confusing
5666 ancient or broken compilers.
5668 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5669 processor/opcode mismatch, so reword the error message.

5808 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5810 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5811 where gcc looks for it.
5813 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5815 * Makefile.in: Changed some lines to be less confusing for some

5881 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5883 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5885 * expr.c (operand): if can't work out what sort of operand it is,
5886 then look through FLT_CHARS for a hint.
5888 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5890 * Makefile.in, configure.in: removed traces of namesubdir,

5892 copyrights to '92, changed some from Cygnus to FSF.
5894 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5895 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5896 copyrights to '92, changed some from Cygnus to FSF.
5898 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5900 * expr.c: If an expression is single comma, then return with
5901 SEG_ABSENT rather than an error - since the sparc front end does
5902 really strange things with things like fbge,a
5904 * as.h: include bfd.h if using many sections
5905 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5906 local labels didn't work.
5907 * listing.c (list_symbol_table): don't core dump when there's no
5909 * write.c, write.h: call fix_new with the right number of args on
5911 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5914 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5916 * app.c: MRI compatibility - allow single quote to start a string.
5917 * as.c: fix typo recently introduced.
5918 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5919 * expr.c: Much rewriting, to accomodate MRI syntax for
5920 expressions. Also easier to read now.
5921 * listing.c: Put back defuns
5922 * read.c: modified to accept MRI syntax, put back listing pseudo
5923 ops so that an assembler built with NO_LISTING ignores list ops
5925 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5926 machine is a SPARC or a 29K.
5927 * config/obj-aout.c: added s_sect pseudo op
5928 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5929 fill in the timestamp.
5930 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5931 anymore, define all the relocs which the tc-<x> bit will use so we
5932 can translate from them to the coff types.
5933 * config/tc-a29k.c: reloc_type isn't ane enum any more
5934 * config/tc-m68k.c: Added NO_RELOC definition.
5936 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5938 * Makefile.in: put header files before C source for TAGS; remove
5939 references to non-existent syscalls.h.
5941 * read.c, write.c subsegs.c: back out the .bss changes.
5943 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5945 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5949 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5951 * symbols.c (local_label_name): symbols now start with ^A.
5953 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5954 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5955 generate these sections. .align: will use NOP_OPCODE or 0
5956 for padding. This is just for being nice to the
5959 * expr.c (operand): changed to generate local label "\001L0"
5960 starting with a ^A so that it is recognized as a local label.
5962 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5964 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5965 i/o opcodes - inb, inw, outb and outw. string manipulation with
5966 att syntax - scmp, slod, smov, ssca, ssto.
5968 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5969 to just after .file .
5971 In obj_crawl_symbol_chain() where it tries to put the external
5972 symbols apart, with the condition:
5973 (!S_IS_DEFINED(symbolP) &&
5974 !S_IS_DEBUG(symbolP) &&
5975 !SF_GET_STATICS(symbolP))
5976 it was moving too many symbols out. So I switch it back to the
5978 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5980 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5981 so that we don't use the F_RELFLG which make the linker complain
5982 that somebody has stripped the relocation info.
5984 Also, the AIX ld program require that the relocation table
5985 is sorted by r_vaddr like the standard ATT assembler does.
5987 [he also changed the sizeof(struct ...)'s into the coff
5988 style FOOSZ macros. I'm not sure this is right, but I can't
5989 remember why. xoxorich.]
5991 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5993 * Makefile.in, configure.in, doc: use the doc. Build it, install
5996 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5998 * read.c: white space and comments only.
6000 * configure.in: use the new atof-ns32.c for ns32k.
6002 * write.c: comment change only.
6004 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6005 aren't yet integrated.
6007 * tc-i860.[hc]: blew off the dust. Something must still be done
6008 about conflicting relocation types.
6010 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6013 * tc-i960.c, tc-sparc.c: white space and comments only.
6015 * tc-a29k.h: delete duplicate macro definition.
6017 * new file atof-ns32k.c copied from hack's last unreleased gas.
6019 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6021 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6024 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6025 ChangeLog's prior to this are sketchy at best. I have logs.
6026 They just aren't ChangeLogs.
