7 * write.c (symbol_table_frozen): New variable, to be set after
8 bfd_set_symtab is called.
9 (dump_section_relocs): Note whether a symbol is a section symbol
11 (adjust_reloc_syms): For now, always supply an absolute symbol for
12 fixups without symbols but not yet `done'. Use section_symbol to
13 get the symbol, instead of going directly for abs_symbol.
14 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
15 reloc is not a section symbol and is not in the symbol table.
16 (set_symtab): New function, broken out from write_object_file.
17 Counts symbol table instead of relying on an earlier count.
18 (write_object_file): Call set_symtab, but do it after potentially
19 invoking the *_frob_file macros. Don't bother counting symbols.
20 Call symbol_remove, instead of expanding it in place. Moved the
21 conditionalized `object_file_size' declaration down to
22 conditionalized block where it's used. When using the absolute
23 symbol for a fixup without a symbol, set sy_used_in_reloc.
24 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
25 the correct symbol for the absolute section.
27 * subsegs.c (section_symbol): Use symbol_new instead of
28 symbol_make, since we may want it to go into the symbol table.
29 Make the new symbol have internal linkage. If
30 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
31 symbol with the newly created GAS symbol.
32 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
33 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

38 (in_signed_range): New function.
40 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
41 (sparc_ip, label "immediate"): Reject constants for pcrel
42 instructions only if the relocation type indicates a "call"
43 instruction and the offset is within range of a "jmpl %g0". If
44 it's not in range, use the absolute section symbol plus an offset.
45 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
47 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
49 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
52 * configure.in: Eliminated all targets using obj-coff but not
53 defining BFD_ASSEMBLER; I think all such targets that are
54 supported will be matched by real CPU-OS combinations earlier in
56 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
57 some comments about the dpx2 configuration, but left it disabled,
58 since it couldn't be reached before.

69 the 'j' operand if there are no further alternatives for this
72 * config/obj-coffbfd.c (adjust_stab_section): Initialize
73 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
74 is not SEG_UNKNOWN rather than checking whether it is >= 0.
76 * config/tc-mips.c (mips_align): Take new argument, label, and use
77 it instead of global insn_label.
78 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
79 call to mips_emit_delay and pass it to mips_align.
81 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
83 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
85 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
86 argument to a .callinfo directive. Don't loop forever on errors.
88 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
89 use pre-defined registers as arguments.
91 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
93 * write.c (write_object_file): Check both S_IS_LOCAL and
94 S_IS_EXTERNAL when deciding whether to discard a symbol.
96 * config-gas.com: Scan Makefile.in, not version.c, for current
97 version number. Delete all versions of temp files when finished
98 with them. Create config.h.
100 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
101 values to reduce number of lookups with S_GET_VALUE. Skip debug
102 symbols to avoid "a really nasty bug". (From Holger Teutsch,
103 holger@botbso.rhein-main.de.)
104 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
105 field. (Also from Holger Teutsch.) Watch for a would-be register
106 mask that spans frags.
108 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
109 this_base, not line_base. (Patch from Andreas Arens,
110 ari@obelix.av.rwth-aachen.de.)
112 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
113 look local if they're exported or undefined. Used to be done for
116 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
117 Get it from the looked-up symbol, instead of using the string from
118 the input stream, which is no longer null-terminated.

120 (lex_type): Use it for `%'.
122 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

1903 pass new argument for i, j and o cases.
1904 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2239 default is to assume production environment, and reject configs
2240 still being worked on. Mark Elf configurations (except sparc and
2241 i386) as developmental. Deleted cases matching some generic names
2242 in favor of more specific names. (E.g., when we get Alpha

2259 through inclusion of tc-hppa.h. Delete all forward declarations
2260 for functions only used within tc-hppa.c, likewise for structures,
2261 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2262 conditional code in a few small places.

2268 into a few places. Make all functions and variables which
2269 are only used within tc-hppa.c static. PARAMize all functions.
2270 Add comments to functions. Delete unused functions, variables,
2271 #defines, etc. Delete unused members within structures. Delete
2272 ldil;ble hacks -- it is believed they were installed to work
2273 around old gas bugs. Avoid using mixed case for local
2274 functions, variables, and structures. Fix formatting problems
2275 not found by GNU-indent. Add FIXME notices for things which
2276 should be worked on the near future. Delete lots of old
2277 useless (1.36 PA-SOM) code.

2350 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2352 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2353 ELF, since the ELF object format does not have these type of
2354 relocations. Change the abort into as as_bad and return
2355 BFD_RELOC_NONE to silence compiler warnings.
2356 (md_assemble): Keep track of the instruction size. Allow white
2357 space between the $ and the constant for compatibility with older
2358 gases and other assemblers.
2359 (i386_operand): Skip spaces between $ and expression.

3420 * Extensive changes to permit symbols to contain any expression
3421 type and to delay the computation of the expression until the
3422 value is actually needed. This permits setting symbols to values
3423 calculated based on object code size. Expressions were changed to
3424 no longer be in a section, to stop the overloading of segment and
3425 expression type that previously occurred.
3427 * as.c (big_section, pass1_section, diff_section, absent_section):

4695 dependencies are read, not when they are used).
4697 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4698 a29k .bss section; the mondfe program doesn't like it.

4743 process relocs if there aren't any relocs to process. Avoids
4744 malloc/free bug on SCO too.

4747 avoid some redefinition complaints on some systems.
4748 (const, volatile): Don't need these conditionally defined if we
4749 use CONST and VOLATILE from ansidecl.h.
4750 (seg_name): Use CONST, not const.
4752 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4754 * config/tc-mips.c: Reindented to GNU standards.

4765 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4767 * Makefile.in: add dvi target; as-$(config).texinfo might live in

4783 bignums, but don't emit error message.
4785 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
4787 * Makefile.in (targ-cpu.o): Depend on config.h.
4789 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4791 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4792 dropping a space immediately following an identifier.
4793 * expr.c, write.c: Rewrote assert expressions to not use multiple
4794 lines; I don't think that can be done portably.
4795 * config/tc-mips.c (macro): Use $AT if target register is zero in
4796 load instruction, which it can be for a floating point load.
4798 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4819 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4821 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4822 to be on a single line.
4824 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4826 * Makefile.in (config.h): Create file, writing out definitions of

4869 * config/tc-mips.c: Rearranged for ECOFF support. Added
4870 prototypes for all static functions. Moved existing minimal
4871 debugging format support info #ifndef OBJ_ECOFF blocks.

4875 (tc_get_register): Renamed from get_register, and made non-static.
4877 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4920 * make-gas.com: Find obstack.obj if it's not in the current
4922 * read.c (s_ignore): Don't declare is_end_of_line. It's
4923 redundant, and triggers a VMS gcc compiler bug.
4925 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4926 current segment as an argument. (Ignored in all cases but VMS.)
4927 All callers and definitions changed.

5223 * config/tc-sparc.c (architecture_requested, warn_on_bump,
5224 md_relax_table): Use default zero initialization.
5225 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5226 latter, instead of selecting with preprocessor conditionals.
5228 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5230 * configure.in: recognise all sparclite variants
5232 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

5238 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5240 * expr.c (operand): If character other than comma or newline is a
5241 logical end-of-line character, use the newline case.
5242 From Eric Youngdale:
5243 (operand): Set X_add_number field for floating-point numbers.
5244 (operand): Treat zero byte as end-of-operand.
5246 * configure.in (per-target): Look for with_bfd_assembler option.
5247 For now, only accept "no", until the merge is done.
5249 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5250 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5251 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5252 * read.c: Finish conversion to S_* macros in the VMS only
5253 parts of the program. Add "const" modifier to hex_value.
5254 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5256 * expr.c: Add "const" modifier to hex_value.
5257 * symbols.c: Finish conversion to S_* macros in the VMS only
5258 parts of the program. Add "const" modifier to
5259 md_[long,short]_jump_size. Remove declaration of const_flag
5260 (which will be declared in obj-vms.h).
5261 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5262 Fix arguments to VMS_write_object_file.
5263 * config-gas.com: New file. Script for VMS systems to set up the
5264 configuration to build gas for VMS, and create config.status.
5265 * make-gas.com: Redone to work with new scheme.
5266 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5268 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5269 will swap bytes if needed on a big endian system. Use throughout
5271 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5272 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5273 types of malformed stabs. Change parsing algorithm so that we are
5274 more certain of having all of the information that we need on hand.
5275 * obj-vms.c (final_forward_reference): New function, used to help
5276 resolve the data types of as many struct elements as possible
5277 when some part of the struct is not fully defined by the compiler.
5278 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5280 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5281 as symbols as well in the object file. Look for external functions
5282 that start with "__vt.", and turn them into variables, since the
5283 g++ compiler is incapable of doing this.
5284 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5286 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5287 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5288 have the name of the source file yet.
5289 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5291 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5293 * read.c (s_data): Always use "data_section", since it'll map to
5294 SEG_DATA or SEG_E1 if needed.
5295 (s_lcomm): Likewise with bss_section.
5296 (s_fill): Use memset, not bzero.
5298 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5319 (section_alignment): Declare only if not BFD_ASSEMBLER.
5320 (big_section, reg_section, pass1_section, diff_section,
5321 absent_section, text_section, data_section, bss_section): If
5322 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5323 mapping to segT enum values.
5324 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5325 if these are used or defined, if BFD_ASSEMBLER.
5326 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5327 subseg_new split into two functions.
5328 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5330 * as.h (volatile): Don't define if already defined.
5331 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5333 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5334 declare with format attribute for -Wformat checking.
5336 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5338 * app.c, config/tc-*.c: Don't include read.h, since it is already
5341 * These are based on patches from Minh Tran-le
5342 <mtranle@paris.intellicorp.com>.
5343 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5344 obj_format coffbfd and gas_target i386coff for target.
5345 (i[34]86-*-isc*): New host (uses sysv).
5346 * config/i386aix.mt: Removed (no longer used).
5347 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5349 (LDFLAGS): Added, defined as -shlib.
5350 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5351 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5352 (DOT_LABEL_PREFIX): Define.
5353 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5354 name rather than L0\001.
5355 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5357 * symbols.c, symbols.h (local_bss_counter): Removed.
5358 * write.c (write_object_file): bss no longer uses
5359 local_bss_counter. Pass correct data and bss size to

5366 (size_section): Restored sanity check.
5367 (do_relocs_for): Base section address on s_paddr rather than
5368 computing it. Adjust a29k R_IHIHALF special case to account for
5369 section paddr (used to require paddr to be zero). If there are no
5370 reclos, set s_relptr to 0. Set relocation size in object_headers.
5371 (fill_section): Always set s_vaddr here, removing
5372 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5373 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5374 Set STYP_INFO for .comment.
5375 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5376 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5378 H_{SET,GET}_* macros.
5379 (do_linenos_for): Set lineno size in object_headers.
5380 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5381 set s_vaddr here. If string_byte_count remains 4, set it back to
5382 0, and only write strings out if there are some. Call
5383 fill_section before do_relocs_for and do_linenos_for.
5384 (obj_coff_section): Handle optional quoted second argument giving
5385 section characteristics.
5386 (obj_coff_bss): Added to handle .bss.
5387 (obj_coff_ident): Added to handle .ident (puts string in .comment

5390 (fixup_mdeps): Change to segment. Call frag_wane after
5392 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5393 adjustment (already happened only for common symbols, but this is
5395 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
5396 * config/tc-i386.c (s_bss): Don't use if I386COFF.

5407 (do_scrub_next_char): For \", return " not '.
5408 (symbol_chars): Now const.
5410 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5411 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5413 * config/obj-coff.h: Don't use #elif.
5415 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5416 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5418 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5442 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5443 using ZERO_BASED_SEGMENTS.
5444 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5445 never set segment address for SEG_E2 (.bss) and don't write out
5446 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5447 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5448 definitions, and don't merge tags with non-tags. Check for .bf
5449 rather than just checking whether the second character is b and
5450 the third character is f.
5451 (obj_coff_val): gcc can generate values which we don't handle
5452 correctly; discard information for now, since it only affects the
5453 debugging information.
5454 (tag_find_or_name): Don't insert tags in the symbol table.
5455 (yank_symbols): Don't merge labels.
5456 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5639 constant will not fit in an immediate field.
5640 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5659 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
5660 so widening works consistently.
5662 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
5664 * version.c: Put conditional "const" before version_string, not
5665 before dummy function for VMS. Now version 1.91.03.
5667 * app.c (do_scrub_next_char): Need double-\ before `000' to show
5668 printed rep of null character.
5670 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
5672 * obj-coffbfd.c (write_object_file): check return value of
5675 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5677 * Support for i386-sysv.
5678 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
5679 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
5680 be used to set them all to zero as was done before.
5681 (fill_section): segment addresses now set in write_object_file.
5682 (fill_section): Don't set STYP_NOLOAD for .bss section.
5683 (fixup_segment): 386 uses strange common symbol format.
5684 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
5685 compatibility with SVR3.2 linker.
5686 * configure.in: i386-sysv and i386-sco use coffbfd.

5697 fix i960+non-bfd coff bit rot.
5698 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
5699 support for C source listings. (obj_coff_endef): look in the right
5700 part of the symbol for the symbol name
5702 * tc-m68k.c (get_num): make it work for all segments, not just the
5705 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
5707 * configure.in: recognize i386-*-bsd emulation.

5716 * tc-z8k.c: lots of bug fixes
5718 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5720 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5721 #elif, since it is not supported by old compilers.
5722 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5723 couple of expressions in tc-m68k.c.
5725 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5727 * read.c (cons): If NO_RELOC is defined, use it.
5729 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5731 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5733 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5734 local labels to start with a .) and set REGISTER_PREFIX to %.
5735 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

5753 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5754 sections starting from zero, rather than making them consecutive.
5755 This makes subsequent reloc calculations easier, esp if the object
5756 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5757 allocate lcomm in .data rather than in .bss. It seems that some
5758 tools can't cope with a non-zero sized bss before linkage.
5760 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5762 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5781 * Makefile.in (install): if $(tooldir) exists, install as in
5784 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5786 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5787 .word is < -32768 or > 32767. The -J flag causes the error to be
5788 ignored. This is to catch over-sized switches generated by gcc on
5789 systems which don't support the broken .word hack.
5790 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5791 write.c (fixup_segment): check for signed .word overflow if
5792 WARN_SIGNED_OVERFLOW_WORD.

5811 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5813 * input-scrub.c (input_scrub_push): call input_file_begin, not
5815 messages.c (as_perror): print ": " between the passed in error and
5816 the strerror, like perror does.
5818 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

5821 From Steve Chamberlain:
5822 Makefile.in: Handle m68*-*-coff*.
5823 read.c, read.h: add mult argument to s_space
5825 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5826 Motorola and MIT syntax; gas can now assemble either type of
5828 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5835 (fixup_segment) set fx_subsy to 0.
5836 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5838 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5841 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5843 * Makefile.in (LIBS): Include opcode library.

5868 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5870 * config/tc-m68k.c (init_table): Now const. Always include 68851
5871 data, so that "bc" is available to 68040 cache instructions.
5872 Added "tt0", "tt1", and 68ec030 variants.
5873 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5874 (enum _register): Added TT0, TT1.
5875 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5876 line number correctly in "internal error" messages. Don't print
5877 architecture-mismatch message for operand errors.
5879 From Colin Smith (colin@wrs.com):
5880 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5881 than install_operand.

5902 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5903 has already been formatted (but may still contain %-characters).
5906 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5908 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5909 written with indirection on the last two operands, which can be
5910 either data or address registers. Added a new operand type 'r'
5911 which accepts either register type. Added '(' to notend stuff in
5912 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5931 their not having symbols associated.
5933 * tc-i960.c (norelax, instrument_branches): Default initializer is
5935 (linkrelax): Delete variable definition.

5959 being used with args swapped, causing occasional lossage when
5960 refilling buffers after an include file.

6139 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
6140 calc the base of relocs correctly.
6141 * tc-a29k.c (parse_operand): allow expressions to be in any section.
6143 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
6145 * as.c, write.c: use -K rather than -k for the broken word warning
6148 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
6150 * Makefile.in: do not print recursion lines.
6152 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6154 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
6156 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6158 * write.c (write_object_file): For b.out format, round up section
6159 start addresses to match required alignment.
6161 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6163 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6164 where gcc looks for it.
6166 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6168 * Makefile.in: Changed some lines to be less confusing for some
6171 * input-file.c: Conditionalize on _IOFBF, not VMS.
6173 * read.c, write.c: Change a series of ifdef/elif to
6174 ifdef/else/ifdef etc.
6176 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
6178 * symbols.c (fb_label_init): fix sizeof to memset.
6180 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
6182 * Makefile.in: install the man page.
6184 * Makefile.in: pass down MAKEINFO explicitly on info.
6186 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
6188 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6190 * flonum-const.c: renamed flonum-konst.c to stop dos name
6193 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
6195 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
6196 tc-m68k.h to te-sun3.h.
6198 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
6200 * configure.in: vxworks68 gets te-sun3.h.
6202 * expr.c: remove limitation that local_labels_dollar or
6203 local_labels_fb must be < 10.
6205 * symbols.c: remove local_labels_dollar, replace with a function
6206 interface for a sparse array. All users adjusted.
6208 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
6210 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6212 * doc/Makefile.in: commented out line for building as-all.texinfo.
6215 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
6217 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
6219 * Makefile.in: added check target.
6221 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6223 * Makefile.in: added tooldir and program_prefix.
6225 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
6227 * write.{c,h} (fix_new): Make these declarations consistent.
6229 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
6231 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6234 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6236 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6238 * expr.c (operand): if can't work out what sort of operand it is,
6239 then look through FLT_CHARS for a hint.
6241 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6243 * Makefile.in, configure.in: removed traces of namesubdir,
6244 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6245 copyrights to '92, changed some from Cygnus to FSF.
6247 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6248 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6249 copyrights to '92, changed some from Cygnus to FSF.
6251 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6253 * expr.c: If an expression is single comma, then return with
6254 SEG_ABSENT rather than an error - since the sparc front end does
6255 really strange things with things like fbge,a
6257 * as.h: include bfd.h if using many sections
6258 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6259 local labels didn't work.
6260 * listing.c (list_symbol_table): don't core dump when there's no
6262 * write.c, write.h: call fix_new with the right number of args on
6264 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6267 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6269 * app.c: MRI compatibility - allow single quote to start a string.
6270 * as.c: fix typo recently introduced.
6271 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6272 * expr.c: Much rewriting, to accomodate MRI syntax for
6273 expressions. Also easier to read now.
6274 * listing.c: Put back defuns
6275 * read.c: modified to accept MRI syntax, put back listing pseudo
6276 ops so that an assembler built with NO_LISTING ignores list ops
6278 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6279 machine is a SPARC or a 29K.
6280 * config/obj-aout.c: added s_sect pseudo op
6281 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6282 fill in the timestamp.
6283 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6284 anymore, define all the relocs which the tc-<x> bit will use so we
6285 can translate from them to the coff types.
6286 * config/tc-a29k.c: reloc_type isn't ane enum any more
6287 * config/tc-m68k.c: Added NO_RELOC definition.
6289 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6291 * Makefile.in: put header files before C source for TAGS; remove
6292 references to non-existent syscalls.h.
6294 * read.c, write.c subsegs.c: back out the .bss changes.
6296 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6298 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6302 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6304 * symbols.c (local_label_name): symbols now start with ^A.
6306 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6307 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6308 generate these sections. .align: will use NOP_OPCODE or 0
6309 for padding. This is just for being nice to the
6312 * expr.c (operand): changed to generate local label "\001L0"
6313 starting with a ^A so that it is recognized as a local label.
6315 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6317 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6318 i/o opcodes - inb, inw, outb and outw. string manipulation with
6319 att syntax - scmp, slod, smov, ssca, ssto.
6321 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6322 to just after .file .
6324 In obj_crawl_symbol_chain() where it tries to put the external
6325 symbols apart, with the condition:
6326 (!S_IS_DEFINED(symbolP) &&
6327 !S_IS_DEBUG(symbolP) &&
6328 !SF_GET_STATICS(symbolP))
6329 it was moving too many symbols out. So I switch it back to the
6331 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6333 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6334 so that we don't use the F_RELFLG which make the linker complain
6335 that somebody has stripped the relocation info.
6337 Also, the AIX ld program require that the relocation table
6338 is sorted by r_vaddr like the standard ATT assembler does.
6340 [he also changed the sizeof(struct ...)'s into the coff
6341 style FOOSZ macros. I'm not sure this is right, but I can't
6342 remember why. xoxorich.]
6344 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6346 * Makefile.in, configure.in, doc: use the doc. Build it, install
6349 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6351 * read.c: white space and comments only.
6353 * configure.in: use the new atof-ns32.c for ns32k.
6355 * write.c: comment change only.
6357 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6358 aren't yet integrated.
6360 * tc-i860.[hc]: blew off the dust. Something must still be done
6361 about conflicting relocation types.
6363 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6366 * tc-i960.c, tc-sparc.c: white space and comments only.
6368 * tc-a29k.h: delete duplicate macro definition.
6370 * new file atof-ns32k.c copied from hack's last unreleased gas.
6372 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6374 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6377 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6378 ChangeLog's prior to this are sketchy at best. I have logs.
6379 They just aren't ChangeLogs.
6383 version-control: never
