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

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

64 * config/tc-mips.c (mips_ip): Only accept overly large values for
65 the 'j' operand if there are no further alternatives for this
68 * config/obj-coffbfd.c (adjust_stab_section): Initialize
69 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
70 is not SEG_UNKNOWN rather than checking whether it is >= 0.
72 * config/tc-mips.c (mips_align): Take new argument, label, and use
73 it instead of global insn_label.
74 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
75 call to mips_emit_delay and pass it to mips_align.
77 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
79 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
81 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
82 argument to a .callinfo directive. Don't loop forever on errors.
84 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
85 use pre-defined registers as arguments.

93 version number. Delete all versions of temp files when finished
94 with them. Create config.h.
96 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
97 values to reduce number of lookups with S_GET_VALUE. Skip debug
98 symbols to avoid "a really nasty bug". (From Holger Teutsch,
99 holger@botbso.rhein-main.de.)
100 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
101 field. (Also from Holger Teutsch.) Watch for a would-be register
102 mask that spans frags.
104 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
105 this_base, not line_base. (Patch from Andreas Arens,
106 ari@obelix.av.rwth-aachen.de.)
108 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
109 look local if they're exported or undefined. Used to be done for
112 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
113 Get it from the looked-up symbol, instead of using the string from
114 the input stream, which is no longer null-terminated.

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

1899 pass new argument for i, j and o cases.
1900 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2177 * write.c (write_relocs): For relocs that are pc_relative and
2178 pcrel_offset and not partial_inplace, adjust reloc->addend to

2234 for keeping or rejecting configurations still under development;
2235 default is to assume production environment, and reject configs
2236 still being worked on. Mark Elf configurations (except sparc and
2237 i386) as developmental. Deleted cases matching some generic names
2238 in favor of more specific names. (E.g., when we get Alpha

2255 through inclusion of tc-hppa.h. Delete all forward declarations
2256 for functions only used within tc-hppa.c, likewise for structures,
2257 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2258 conditional code in a few small places.
2260 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group

2263 conditional code -- try to group conditional code together
2264 into a few places. Make all functions and variables which
2265 are only used within tc-hppa.c static. PARAMize all functions.
2266 Add comments to functions. Delete unused functions, variables,
2267 #defines, etc. Delete unused members within structures. Delete
2268 ldil;ble hacks -- it is believed they were installed to work
2269 around old gas bugs. Avoid using mixed case for local
2270 functions, variables, and structures. Fix formatting problems
2271 not found by GNU-indent. Add FIXME notices for things which
2272 should be worked on the near future. Delete lots of old
2273 useless (1.36 PA-SOM) code.

2346 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2348 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2349 ELF, since the ELF object format does not have these type of
2350 relocations. Change the abort into as as_bad and return
2351 BFD_RELOC_NONE to silence compiler warnings.
2352 (md_assemble): Keep track of the instruction size. Allow white
2353 space between the $ and the constant for compatibility with older
2354 gases and other assemblers.
2355 (i386_operand): Skip spaces between $ and expression.

3305 w/ ANSI, and which weren't needed anyway
3307 Wed Jul 28 16:34:55 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3309 * config/obj-elf.h (obj_frob_symbol): Renamed from tc_frob_symbol,

3351 are also magic, and have special default flag settings.
3352 (obj_elf_frob_symbol): Since the return value from this function

3416 * Extensive changes to permit symbols to contain any expression
3417 type and to delay the computation of the expression until the
3418 value is actually needed. This permits setting symbols to values
3419 calculated based on object code size. Expressions were changed to
3420 no longer be in a section, to stop the overloading of segment and
3421 expression type that previously occurred.
3423 * as.c (big_section, pass1_section, diff_section, absent_section):
3425 (expr_section): Added (used for dummy symbols which hold

3511 to pop back to it. Handle unquoted section name as well as quoted
3512 section name. Don't crash on invalid strings.

3625 sy_resolved and sy_resolving single bit fields.
3626 * symbols.c (symbol_new): Don't initialize sy_forward field.

4690 the bottom (make expands variables in dependencies when the
4691 dependencies are read, not when they are used).
4693 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4694 a29k .bss section; the mondfe program doesn't like it.

4709 (srcdir): Delete second, bogus definition.
4710 (as.info): Look for as-*.texinfo in current directory rather than
4714 * doc/configure.in: Create links to all as-*.texinfo files in the
4715 source directory, if that's not the current directory.
4717 * configure.in (per-host): Accept MIPS host with BSD version

4735 * doc/as.texinfo: Updated description of -a* (listing) options,
4736 and describe how to pass them through from gcc.
4738 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
4739 process relocs if there aren't any relocs to process. Avoids
4740 malloc/free bug on SCO too.
4742 * as.h: Move local include files below system include files, to
4743 avoid some redefinition complaints on some systems.
4744 (const, volatile): Don't need these conditionally defined if we
4745 use CONST and VOLATILE from ansidecl.h.
4746 (seg_name): Use CONST, not const.
4748 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4750 * config/tc-mips.c: Reindented to GNU standards.
4752 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
4754 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4755 (fixup_segment): Add a29k special case; the linker is not prepared
4756 to see a segment offset here.
4758 * app.c (do_scrub_next_char): Added new state, 10, modifying state
4759 9 to only keep a space in between identifier characters.
4761 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4763 * Makefile.in: add dvi target; as-$(config).texinfo might live in

4779 bignums, but don't emit error message.
4781 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
4783 * Makefile.in (targ-cpu.o): Depend on config.h.
4785 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4787 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4788 dropping a space immediately following an identifier.
4789 * expr.c, write.c: Rewrote assert expressions to not use multiple
4790 lines; I don't think that can be done portably.
4791 * config/tc-mips.c (macro): Use $AT if target register is zero in
4792 load instruction, which it can be for a floating point load.
4794 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
4796 * write.c (write_contents): Compute the relocs before writing out

4815 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4817 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4818 to be on a single line.
4820 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4822 * Makefile.in (config.h): Create file, writing out definitions of

4864 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
4865 * config/tc-mips.c: Rearranged for ECOFF support. Added
4866 prototypes for all static functions. Moved existing minimal
4867 debugging format support info #ifndef OBJ_ECOFF blocks.
4868 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
4869 does not support a non sign extended high 16 bits reloc. Adjusted
4870 all callers accordingly.
4871 (tc_get_register): Renamed from get_register, and made non-static.
4873 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4916 * make-gas.com: Find obstack.obj if it's not in the current
4918 * read.c (s_ignore): Don't declare is_end_of_line. It's
4919 redundant, and triggers a VMS gcc compiler bug.
4921 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4922 current segment as an argument. (Ignored in all cases but VMS.)
4923 All callers and definitions changed.

5219 * config/tc-sparc.c (architecture_requested, warn_on_bump,
5220 md_relax_table): Use default zero initialization.
5221 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5222 latter, instead of selecting with preprocessor conditionals.
5224 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5226 * configure.in: recognise all sparclite variants
5228 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5230 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --

5234 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5236 * expr.c (operand): If character other than comma or newline is a
5237 logical end-of-line character, use the newline case.
5238 From Eric Youngdale:
5239 (operand): Set X_add_number field for floating-point numbers.
5240 (operand): Treat zero byte as end-of-operand.
5242 * configure.in (per-target): Look for with_bfd_assembler option.
5243 For now, only accept "no", until the merge is done.
5245 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5246 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5247 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5248 * read.c: Finish conversion to S_* macros in the VMS only
5249 parts of the program. Add "const" modifier to hex_value.
5250 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5252 * expr.c: Add "const" modifier to hex_value.
5253 * symbols.c: Finish conversion to S_* macros in the VMS only
5254 parts of the program. Add "const" modifier to
5255 md_[long,short]_jump_size. Remove declaration of const_flag
5256 (which will be declared in obj-vms.h).
5257 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5258 Fix arguments to VMS_write_object_file.
5259 * config-gas.com: New file. Script for VMS systems to set up the
5260 configuration to build gas for VMS, and create config.status.
5261 * make-gas.com: Redone to work with new scheme.
5262 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5264 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5265 will swap bytes if needed on a big endian system. Use throughout
5267 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5268 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5269 types of malformed stabs. Change parsing algorithm so that we are
5270 more certain of having all of the information that we need on hand.
5271 * obj-vms.c (final_forward_reference): New function, used to help
5272 resolve the data types of as many struct elements as possible
5273 when some part of the struct is not fully defined by the compiler.
5274 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5276 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5277 as symbols as well in the object file. Look for external functions
5278 that start with "__vt.", and turn them into variables, since the
5279 g++ compiler is incapable of doing this.
5280 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5282 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5283 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5284 have the name of the source file yet.
5285 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5287 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5289 * read.c (s_data): Always use "data_section", since it'll map to
5290 SEG_DATA or SEG_E1 if needed.
5291 (s_lcomm): Likewise with bss_section.
5292 (s_fill): Use memset, not bzero.
5294 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
5296 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

5315 (section_alignment): Declare only if not BFD_ASSEMBLER.
5316 (big_section, reg_section, pass1_section, diff_section,
5317 absent_section, text_section, data_section, bss_section): If
5318 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5319 mapping to segT enum values.
5320 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5321 if these are used or defined, if BFD_ASSEMBLER.
5322 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5323 subseg_new split into two functions.
5324 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5326 * as.h (volatile): Don't define if already defined.
5327 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5329 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5330 declare with format attribute for -Wformat checking.
5332 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5334 * app.c, config/tc-*.c: Don't include read.h, since it is already
5337 * These are based on patches from Minh Tran-le
5338 <mtranle@paris.intellicorp.com>.
5339 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5340 obj_format coffbfd and gas_target i386coff for target.
5341 (i[34]86-*-isc*): New host (uses sysv).
5342 * config/i386aix.mt: Removed (no longer used).
5343 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5345 (LDFLAGS): Added, defined as -shlib.
5346 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5347 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5348 (DOT_LABEL_PREFIX): Define.
5349 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5350 name rather than L0\001.
5351 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5353 * symbols.c, symbols.h (local_bss_counter): Removed.
5354 * write.c (write_object_file): bss no longer uses
5355 local_bss_counter. Pass correct data and bss size to
5356 VMS_write_object_file.

5362 (size_section): Restored sanity check.
5363 (do_relocs_for): Base section address on s_paddr rather than
5364 computing it. Adjust a29k R_IHIHALF special case to account for
5365 section paddr (used to require paddr to be zero). If there are no
5366 reclos, set s_relptr to 0. Set relocation size in object_headers.
5367 (fill_section): Always set s_vaddr here, removing
5368 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5369 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5370 Set STYP_INFO for .comment.
5371 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5372 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5374 H_{SET,GET}_* macros.
5375 (do_linenos_for): Set lineno size in object_headers.
5376 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5377 set s_vaddr here. If string_byte_count remains 4, set it back to
5378 0, and only write strings out if there are some. Call
5379 fill_section before do_relocs_for and do_linenos_for.
5380 (obj_coff_section): Handle optional quoted second argument giving
5381 section characteristics.
5382 (obj_coff_bss): Added to handle .bss.
5383 (obj_coff_ident): Added to handle .ident (puts string in .comment

5386 (fixup_mdeps): Change to segment. Call frag_wane after
5388 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5389 adjustment (already happened only for common symbols, but this is
5391 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

5403 (do_scrub_next_char): For \", return " not '.
5404 (symbol_chars): Now const.
5406 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5407 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5409 * config/obj-coff.h: Don't use #elif.
5411 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5412 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5414 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5438 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5439 using ZERO_BASED_SEGMENTS.
5440 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5441 never set segment address for SEG_E2 (.bss) and don't write out
5442 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5443 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5444 definitions, and don't merge tags with non-tags. Check for .bf
5445 rather than just checking whether the second character is b and
5446 the third character is f.
5447 (obj_coff_val): gcc can generate values which we don't handle
5448 correctly; discard information for now, since it only affects the
5449 debugging information.

5451 (yank_symbols): Don't merge labels.
5452 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5634 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5635 constant will not fit in an immediate field.
5636 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5663 * app.c (do_scrub_next_char): Need double-\ before `000' to show
5664 printed rep of null character.
5666 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)

5671 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5673 * Support for i386-sysv.
5674 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
5675 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
5676 be used to set them all to zero as was done before.
5677 (fill_section): segment addresses now set in write_object_file.
5678 (fill_section): Don't set STYP_NOLOAD for .bss section.
5679 (fixup_segment): 386 uses strange common symbol format.
5680 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
5681 compatibility with SVR3.2 linker.
5682 * configure.in: i386-sysv and i386-sco use coffbfd.

5694 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
5695 support for C source listings. (obj_coff_endef): look in the right
5696 part of the symbol for the symbol name
5698 * tc-m68k.c (get_num): make it work for all segments, not just the
5701 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
5703 * configure.in: recognize i386-*-bsd emulation.

5712 * tc-z8k.c: lots of bug fixes
5714 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5716 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5717 #elif, since it is not supported by old compilers.
5718 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5719 couple of expressions in tc-m68k.c.
5721 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5723 * read.c (cons): If NO_RELOC is defined, use it.
5725 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5727 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5729 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5730 local labels to start with a .) and set REGISTER_PREFIX to %.
5731 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

5749 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5750 sections starting from zero, rather than making them consecutive.
5751 This makes subsequent reloc calculations easier, esp if the object
5752 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5753 allocate lcomm in .data rather than in .bss. It seems that some
5754 tools can't cope with a non-zero sized bss before linkage.
5756 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5758 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5780 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5782 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5783 .word is < -32768 or > 32767. The -J flag causes the error to be
5784 ignored. This is to catch over-sized switches generated by gcc on
5785 systems which don't support the broken .word hack.
5786 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5787 write.c (fixup_segment): check for signed .word overflow if
5788 WARN_SIGNED_OVERFLOW_WORD.
5790 * write.c (fixup_segment): fixed missing parens in expression
5791 checking for byte or word overflow.

5807 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5809 * input-scrub.c (input_scrub_push): call input_file_begin, not
5811 messages.c (as_perror): print ": " between the passed in error and
5812 the strerror, like perror does.
5814 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

5817 From Steve Chamberlain:
5818 Makefile.in: Handle m68*-*-coff*.
5819 read.c, read.h: add mult argument to s_space
5821 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5822 Motorola and MIT syntax; gas can now assemble either type of
5824 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5832 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5834 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5837 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5839 * Makefile.in (LIBS): Include opcode library.

5864 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5866 * config/tc-m68k.c (init_table): Now const. Always include 68851
5867 data, so that "bc" is available to 68040 cache instructions.
5868 Added "tt0", "tt1", and 68ec030 variants.
5869 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5870 (enum _register): Added TT0, TT1.
5871 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5872 line number correctly in "internal error" messages. Don't print
5873 architecture-mismatch message for operand errors.
5875 From Colin Smith (colin@wrs.com):
5876 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

5898 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5899 has already been formatted (but may still contain %-characters).
5902 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5904 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5905 written with indirection on the last two operands, which can be
5906 either data or address registers. Added a new operand type 'r'
5907 which accepts either register type. Added '(' to notend stuff in
5908 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6015 ancient or broken compilers.
6017 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
6018 processor/opcode mismatch, so reword the error message.

6141 * as.c, write.c: use -K rather than -k for the broken word warning
6144 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
6146 * Makefile.in: do not print recursion lines.
6148 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6150 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
6152 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6154 * write.c (write_object_file): For b.out format, round up section
6155 start addresses to match required alignment.
6157 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6159 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6160 where gcc looks for it.
6162 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6164 * Makefile.in: Changed some lines to be less confusing for some
6167 * input-file.c: Conditionalize on _IOFBF, not VMS.
6169 * read.c, write.c: Change a series of ifdef/elif to
6170 ifdef/else/ifdef etc.
6172 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
6174 * symbols.c (fb_label_init): fix sizeof to memset.
6176 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
6178 * Makefile.in: install the man page.
6180 * Makefile.in: pass down MAKEINFO explicitly on info.
6182 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
6184 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6186 * flonum-const.c: renamed flonum-konst.c to stop dos name
6189 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
6191 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
6192 tc-m68k.h to te-sun3.h.
6194 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
6196 * configure.in: vxworks68 gets te-sun3.h.
6198 * expr.c: remove limitation that local_labels_dollar or
6199 local_labels_fb must be < 10.
6201 * symbols.c: remove local_labels_dollar, replace with a function
6202 interface for a sparse array. All users adjusted.
6204 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
6206 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6208 * doc/Makefile.in: commented out line for building as-all.texinfo.
6211 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
6213 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
6215 * Makefile.in: added check target.
6217 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6219 * Makefile.in: added tooldir and program_prefix.
6221 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
6223 * write.{c,h} (fix_new): Make these declarations consistent.
6225 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
6227 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6230 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6232 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6234 * expr.c (operand): if can't work out what sort of operand it is,
6235 then look through FLT_CHARS for a hint.
6237 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6239 * Makefile.in, configure.in: removed traces of namesubdir,
6240 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6241 copyrights to '92, changed some from Cygnus to FSF.
6243 * doc/Makefile.in, doc/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 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6249 * expr.c: If an expression is single comma, then return with
6250 SEG_ABSENT rather than an error - since the sparc front end does
6251 really strange things with things like fbge,a
6253 * as.h: include bfd.h if using many sections
6254 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6255 local labels didn't work.
6256 * listing.c (list_symbol_table): don't core dump when there's no
6258 * write.c, write.h: call fix_new with the right number of args on
6260 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6263 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6265 * app.c: MRI compatibility - allow single quote to start a string.
6266 * as.c: fix typo recently introduced.
6267 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6268 * expr.c: Much rewriting, to accomodate MRI syntax for
6269 expressions. Also easier to read now.
6270 * listing.c: Put back defuns
6271 * read.c: modified to accept MRI syntax, put back listing pseudo
6272 ops so that an assembler built with NO_LISTING ignores list ops
6274 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6275 machine is a SPARC or a 29K.
6276 * config/obj-aout.c: added s_sect pseudo op
6277 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6278 fill in the timestamp.
6279 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6280 anymore, define all the relocs which the tc-<x> bit will use so we
6281 can translate from them to the coff types.
6282 * config/tc-a29k.c: reloc_type isn't ane enum any more
6283 * config/tc-m68k.c: Added NO_RELOC definition.
6285 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6287 * Makefile.in: put header files before C source for TAGS; remove
6288 references to non-existent syscalls.h.
6290 * read.c, write.c subsegs.c: back out the .bss changes.
6292 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6294 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6298 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6300 * symbols.c (local_label_name): symbols now start with ^A.
6302 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6303 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6304 generate these sections. .align: will use NOP_OPCODE or 0
6305 for padding. This is just for being nice to the
6308 * expr.c (operand): changed to generate local label "\001L0"
6309 starting with a ^A so that it is recognized as a local label.
6311 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6313 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6314 i/o opcodes - inb, inw, outb and outw. string manipulation with
6315 att syntax - scmp, slod, smov, ssca, ssto.
6317 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6318 to just after .file .
6320 In obj_crawl_symbol_chain() where it tries to put the external
6321 symbols apart, with the condition:
6322 (!S_IS_DEFINED(symbolP) &&
6323 !S_IS_DEBUG(symbolP) &&
6324 !SF_GET_STATICS(symbolP))
6325 it was moving too many symbols out. So I switch it back to the
6327 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6329 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6330 so that we don't use the F_RELFLG which make the linker complain
6331 that somebody has stripped the relocation info.
6333 Also, the AIX ld program require that the relocation table
6334 is sorted by r_vaddr like the standard ATT assembler does.
6336 [he also changed the sizeof(struct ...)'s into the coff
6337 style FOOSZ macros. I'm not sure this is right, but I can't
6338 remember why. xoxorich.]
6340 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6342 * Makefile.in, configure.in, doc: use the doc. Build it, install
6345 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6347 * read.c: white space and comments only.
6349 * configure.in: use the new atof-ns32.c for ns32k.
6351 * write.c: comment change only.
6353 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6354 aren't yet integrated.
6356 * tc-i860.[hc]: blew off the dust. Something must still be done
6357 about conflicting relocation types.
6359 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6362 * tc-i960.c, tc-sparc.c: white space and comments only.
6364 * tc-a29k.h: delete duplicate macro definition.
6366 * new file atof-ns32k.c copied from hack's last unreleased gas.
6368 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6370 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6373 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6374 ChangeLog's prior to this are sketchy at best. I have logs.
6375 They just aren't ChangeLogs.
6379 version-control: never
