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

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

73 the 'j' operand if there are no further alternatives for this
76 * config/obj-coffbfd.c (adjust_stab_section): Initialize
77 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
78 is not SEG_UNKNOWN rather than checking whether it is >= 0.
80 * config/tc-mips.c (mips_align): Take new argument, label, and use
81 it instead of global insn_label.
82 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
83 call to mips_emit_delay and pass it to mips_align.
85 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
87 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
89 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
90 argument to a .callinfo directive. Don't loop forever on errors.
92 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
93 use pre-defined registers as arguments.
95 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
97 * write.c (write_object_file): Check both S_IS_LOCAL and
98 S_IS_EXTERNAL when deciding whether to discard a symbol.

101 version number. Delete all versions of temp files when finished
102 with them. Create config.h.
104 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
105 values to reduce number of lookups with S_GET_VALUE. Skip debug
106 symbols to avoid "a really nasty bug". (From Holger Teutsch,
107 holger@botbso.rhein-main.de.)
108 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
109 field. (Also from Holger Teutsch.) Watch for a would-be register
110 mask that spans frags.
112 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
113 this_base, not line_base. (Patch from Andreas Arens,
114 ari@obelix.av.rwth-aachen.de.)
116 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
117 look local if they're exported or undefined. Used to be done for
120 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

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

1907 pass new argument for i, j and o cases.
1908 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2243 default is to assume production environment, and reject configs
2244 still being worked on. Mark Elf configurations (except sparc and
2245 i386) as developmental. Deleted cases matching some generic names
2246 in favor of more specific names. (E.g., when we get Alpha

2263 through inclusion of tc-hppa.h. Delete all forward declarations
2264 for functions only used within tc-hppa.c, likewise for structures,
2265 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2266 conditional code in a few small places.

2272 into a few places. Make all functions and variables which
2273 are only used within tc-hppa.c static. PARAMize all functions.
2274 Add comments to functions. Delete unused functions, variables,
2275 #defines, etc. Delete unused members within structures. Delete
2276 ldil;ble hacks -- it is believed they were installed to work
2277 around old gas bugs. Avoid using mixed case for local
2278 functions, variables, and structures. Fix formatting problems
2279 not found by GNU-indent. Add FIXME notices for things which
2280 should be worked on the near future. Delete lots of old
2281 useless (1.36 PA-SOM) code.

2354 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2356 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2357 ELF, since the ELF object format does not have these type of
2358 relocations. Change the abort into as as_bad and return
2359 BFD_RELOC_NONE to silence compiler warnings.
2360 (md_assemble): Keep track of the instruction size. Allow white
2361 space between the $ and the constant for compatibility with older
2362 gases and other assemblers.
2363 (i386_operand): Skip spaces between $ and expression.
2364 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

3424 * Extensive changes to permit symbols to contain any expression
3425 type and to delay the computation of the expression until the
3426 value is actually needed. This permits setting symbols to values
3427 calculated based on object code size. Expressions were changed to
3428 no longer be in a section, to stop the overloading of segment and
3429 expression type that previously occurred.
3431 * as.c (big_section, pass1_section, diff_section, absent_section):
3433 (expr_section): Added (used for dummy symbols which hold

4699 dependencies are read, not when they are used).
4701 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4702 a29k .bss section; the mondfe program doesn't like it.

4747 process relocs if there aren't any relocs to process. Avoids
4748 malloc/free bug on SCO too.

4751 avoid some redefinition complaints on some systems.
4752 (const, volatile): Don't need these conditionally defined if we
4753 use CONST and VOLATILE from ansidecl.h.
4754 (seg_name): Use CONST, not const.
4756 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4758 * config/tc-mips.c: Reindented to GNU standards.

4762 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4763 (fixup_segment): Add a29k special case; the linker is not prepared
4764 to see a segment offset here.

4769 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4771 * Makefile.in: add dvi target; as-$(config).texinfo might live in

4787 bignums, but don't emit error message.
4789 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
4791 * Makefile.in (targ-cpu.o): Depend on config.h.
4793 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4795 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4796 dropping a space immediately following an identifier.
4797 * expr.c, write.c: Rewrote assert expressions to not use multiple
4798 lines; I don't think that can be done portably.
4799 * config/tc-mips.c (macro): Use $AT if target register is zero in
4800 load instruction, which it can be for a floating point load.
4802 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4823 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4825 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4826 to be on a single line.
4828 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

4873 * config/tc-mips.c: Rearranged for ECOFF support. Added
4874 prototypes for all static functions. Moved existing minimal
4875 debugging format support info #ifndef OBJ_ECOFF blocks.

4879 (tc_get_register): Renamed from get_register, and made non-static.
4881 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4924 * make-gas.com: Find obstack.obj if it's not in the current
4926 * read.c (s_ignore): Don't declare is_end_of_line. It's
4927 redundant, and triggers a VMS gcc compiler bug.
4929 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4930 current segment as an argument. (Ignored in all cases but VMS.)
4931 All callers and definitions changed.

5227 * config/tc-sparc.c (architecture_requested, warn_on_bump,
5228 md_relax_table): Use default zero initialization.
5229 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5230 latter, instead of selecting with preprocessor conditionals.
5232 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5234 * configure.in: recognise all sparclite variants
5236 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

5242 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5244 * expr.c (operand): If character other than comma or newline is a
5245 logical end-of-line character, use the newline case.
5246 From Eric Youngdale:
5247 (operand): Set X_add_number field for floating-point numbers.
5248 (operand): Treat zero byte as end-of-operand.
5250 * configure.in (per-target): Look for with_bfd_assembler option.
5251 For now, only accept "no", until the merge is done.
5253 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5254 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5255 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5256 * read.c: Finish conversion to S_* macros in the VMS only
5257 parts of the program. Add "const" modifier to hex_value.

5260 * expr.c: Add "const" modifier to hex_value.
5261 * symbols.c: Finish conversion to S_* macros in the VMS only
5262 parts of the program. Add "const" modifier to
5263 md_[long,short]_jump_size. Remove declaration of const_flag
5264 (which will be declared in obj-vms.h).
5265 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5266 Fix arguments to VMS_write_object_file.
5267 * config-gas.com: New file. Script for VMS systems to set up the
5268 configuration to build gas for VMS, and create config.status.
5269 * make-gas.com: Redone to work with new scheme.
5270 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5272 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5273 will swap bytes if needed on a big endian system. Use throughout
5275 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5276 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5277 types of malformed stabs. Change parsing algorithm so that we are
5278 more certain of having all of the information that we need on hand.
5279 * obj-vms.c (final_forward_reference): New function, used to help
5280 resolve the data types of as many struct elements as possible
5281 when some part of the struct is not fully defined by the compiler.

5284 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5285 as symbols as well in the object file. Look for external functions
5286 that start with "__vt.", and turn them into variables, since the
5287 g++ compiler is incapable of doing this.
5288 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5290 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5291 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5292 have the name of the source file yet.
5293 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5295 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5297 * read.c (s_data): Always use "data_section", since it'll map to
5298 SEG_DATA or SEG_E1 if needed.
5299 (s_lcomm): Likewise with bss_section.
5300 (s_fill): Use memset, not bzero.
5302 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5323 (section_alignment): Declare only if not BFD_ASSEMBLER.
5324 (big_section, reg_section, pass1_section, diff_section,
5325 absent_section, text_section, data_section, bss_section): If
5326 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5327 mapping to segT enum values.
5328 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5329 if these are used or defined, if BFD_ASSEMBLER.
5330 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5331 subseg_new split into two functions.
5332 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5334 * as.h (volatile): Don't define if already defined.
5335 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5337 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5338 declare with format attribute for -Wformat checking.
5340 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5342 * app.c, config/tc-*.c: Don't include read.h, since it is already
5345 * These are based on patches from Minh Tran-le
5346 <mtranle@paris.intellicorp.com>.
5347 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5348 obj_format coffbfd and gas_target i386coff for target.
5349 (i[34]86-*-isc*): New host (uses sysv).
5350 * config/i386aix.mt: Removed (no longer used).
5351 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5353 (LDFLAGS): Added, defined as -shlib.
5354 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5355 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5356 (DOT_LABEL_PREFIX): Define.
5357 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5358 name rather than L0\001.
5359 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5361 * symbols.c, symbols.h (local_bss_counter): Removed.
5362 * write.c (write_object_file): bss no longer uses
5363 local_bss_counter. Pass correct data and bss size to

5370 (size_section): Restored sanity check.
5371 (do_relocs_for): Base section address on s_paddr rather than
5372 computing it. Adjust a29k R_IHIHALF special case to account for
5373 section paddr (used to require paddr to be zero). If there are no
5374 reclos, set s_relptr to 0. Set relocation size in object_headers.
5375 (fill_section): Always set s_vaddr here, removing
5376 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5377 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5378 Set STYP_INFO for .comment.

5382 H_{SET,GET}_* macros.
5383 (do_linenos_for): Set lineno size in object_headers.
5384 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5385 set s_vaddr here. If string_byte_count remains 4, set it back to
5386 0, and only write strings out if there are some. Call
5387 fill_section before do_relocs_for and do_linenos_for.
5388 (obj_coff_section): Handle optional quoted second argument giving
5389 section characteristics.
5390 (obj_coff_bss): Added to handle .bss.
5391 (obj_coff_ident): Added to handle .ident (puts string in .comment

5411 (do_scrub_next_char): For \", return " not '.
5412 (symbol_chars): Now const.
5414 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5415 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5417 * config/obj-coff.h: Don't use #elif.
5419 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5420 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5447 using ZERO_BASED_SEGMENTS.
5448 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5449 never set segment address for SEG_E2 (.bss) and don't write out
5450 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5451 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5452 definitions, and don't merge tags with non-tags. Check for .bf
5453 rather than just checking whether the second character is b and
5454 the third character is f.
5455 (obj_coff_val): gcc can generate values which we don't handle
5456 correctly; discard information for now, since it only affects the
5457 debugging information.

5459 (yank_symbols): Don't merge labels.
5460 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5663 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
5664 so widening works consistently.
5666 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
5668 * version.c: Put conditional "const" before version_string, not
5669 before dummy function for VMS. Now version 1.91.03.
5671 * app.c (do_scrub_next_char): Need double-\ before `000' to show
5672 printed rep of null character.
5674 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
5676 * obj-coffbfd.c (write_object_file): check return value of
5679 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5681 * Support for i386-sysv.
5682 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
5683 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
5684 be used to set them all to zero as was done before.
5685 (fill_section): segment addresses now set in write_object_file.
5686 (fill_section): Don't set STYP_NOLOAD for .bss section.
5687 (fixup_segment): 386 uses strange common symbol format.
5688 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
5689 compatibility with SVR3.2 linker.
5690 * configure.in: i386-sysv and i386-sco use coffbfd.

5701 fix i960+non-bfd coff bit rot.
5702 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
5703 support for C source listings. (obj_coff_endef): look in the right
5704 part of the symbol for the symbol name
5706 * tc-m68k.c (get_num): make it work for all segments, not just the
5709 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
5711 * configure.in: recognize i386-*-bsd emulation.

5720 * tc-z8k.c: lots of bug fixes
5722 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5724 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5725 #elif, since it is not supported by old compilers.
5726 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5727 couple of expressions in tc-m68k.c.
5729 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5731 * read.c (cons): If NO_RELOC is defined, use it.
5733 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5735 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5737 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5738 local labels to start with a .) and set REGISTER_PREFIX to %.
5739 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

5757 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5758 sections starting from zero, rather than making them consecutive.
5759 This makes subsequent reloc calculations easier, esp if the object
5760 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5761 allocate lcomm in .data rather than in .bss. It seems that some
5762 tools can't cope with a non-zero sized bss before linkage.
5764 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5766 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5785 * Makefile.in (install): if $(tooldir) exists, install as in
5788 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5790 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5791 .word is < -32768 or > 32767. The -J flag causes the error to be
5792 ignored. This is to catch over-sized switches generated by gcc on
5793 systems which don't support the broken .word hack.
5794 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5795 write.c (fixup_segment): check for signed .word overflow if
5796 WARN_SIGNED_OVERFLOW_WORD.
5798 * write.c (fixup_segment): fixed missing parens in expression
5799 checking for byte or word overflow.

5815 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5817 * input-scrub.c (input_scrub_push): call input_file_begin, not
5819 messages.c (as_perror): print ": " between the passed in error and
5820 the strerror, like perror does.
5822 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

5825 From Steve Chamberlain:
5826 Makefile.in: Handle m68*-*-coff*.
5827 read.c, read.h: add mult argument to s_space
5829 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5830 Motorola and MIT syntax; gas can now assemble either type of
5832 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5839 (fixup_segment) set fx_subsy to 0.
5840 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5842 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5845 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5847 * Makefile.in (LIBS): Include opcode library.

5872 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5874 * config/tc-m68k.c (init_table): Now const. Always include 68851
5875 data, so that "bc" is available to 68040 cache instructions.
5876 Added "tt0", "tt1", and 68ec030 variants.
5877 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5878 (enum _register): Added TT0, TT1.
5879 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5880 line number correctly in "internal error" messages. Don't print
5881 architecture-mismatch message for operand errors.
5883 From Colin Smith (colin@wrs.com):
5884 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5885 than install_operand.

5906 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5907 has already been formatted (but may still contain %-characters).
5910 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5912 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5913 written with indirection on the last two operands, which can be
5914 either data or address registers. Added a new operand type 'r'
5915 which accepts either register type. Added '(' to notend stuff in
5916 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5935 their not having symbols associated.
5937 * tc-i960.c (norelax, instrument_branches): Default initializer is

5963 being used with args swapped, causing occasional lossage when
5964 refilling buffers after an include file.

6023 ancient or broken compilers.
6025 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
6026 processor/opcode mismatch, so reword the error message.

6143 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
6144 calc the base of relocs correctly.
6145 * tc-a29k.c (parse_operand): allow expressions to be in any section.
6147 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
6149 * as.c, write.c: use -K rather than -k for the broken word warning
6152 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
6154 * Makefile.in: do not print recursion lines.
6156 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6158 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
6160 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6162 * write.c (write_object_file): For b.out format, round up section
6163 start addresses to match required alignment.
6165 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6167 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6168 where gcc looks for it.
6170 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6172 * Makefile.in: Changed some lines to be less confusing for some
6175 * input-file.c: Conditionalize on _IOFBF, not VMS.
6177 * read.c, write.c: Change a series of ifdef/elif to
6178 ifdef/else/ifdef etc.
6180 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
6182 * symbols.c (fb_label_init): fix sizeof to memset.
6184 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
6186 * Makefile.in: install the man page.
6188 * Makefile.in: pass down MAKEINFO explicitly on info.
6190 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
6192 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6194 * flonum-const.c: renamed flonum-konst.c to stop dos name
6197 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
6199 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
6200 tc-m68k.h to te-sun3.h.
6202 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
6204 * configure.in: vxworks68 gets te-sun3.h.
6206 * expr.c: remove limitation that local_labels_dollar or
6207 local_labels_fb must be < 10.
6209 * symbols.c: remove local_labels_dollar, replace with a function
6210 interface for a sparse array. All users adjusted.
6212 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
6214 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6216 * doc/Makefile.in: commented out line for building as-all.texinfo.
6219 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
6221 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
6223 * Makefile.in: added check target.
6225 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6227 * Makefile.in: added tooldir and program_prefix.
6229 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
6231 * write.{c,h} (fix_new): Make these declarations consistent.
6233 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
6235 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6238 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6240 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6242 * expr.c (operand): if can't work out what sort of operand it is,
6243 then look through FLT_CHARS for a hint.
6245 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6247 * Makefile.in, 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 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6252 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6253 copyrights to '92, changed some from Cygnus to FSF.
6255 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6257 * expr.c: If an expression is single comma, then return with
6258 SEG_ABSENT rather than an error - since the sparc front end does
6259 really strange things with things like fbge,a
6261 * as.h: include bfd.h if using many sections
6262 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6263 local labels didn't work.
6264 * listing.c (list_symbol_table): don't core dump when there's no
6266 * write.c, write.h: call fix_new with the right number of args on
6268 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6271 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6273 * app.c: MRI compatibility - allow single quote to start a string.
6274 * as.c: fix typo recently introduced.
6275 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6276 * expr.c: Much rewriting, to accomodate MRI syntax for
6277 expressions. Also easier to read now.
6278 * listing.c: Put back defuns
6279 * read.c: modified to accept MRI syntax, put back listing pseudo
6280 ops so that an assembler built with NO_LISTING ignores list ops
6282 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6283 machine is a SPARC or a 29K.
6284 * config/obj-aout.c: added s_sect pseudo op
6285 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6286 fill in the timestamp.
6287 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6288 anymore, define all the relocs which the tc-<x> bit will use so we
6289 can translate from them to the coff types.
6290 * config/tc-a29k.c: reloc_type isn't ane enum any more
6291 * config/tc-m68k.c: Added NO_RELOC definition.
6293 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6295 * Makefile.in: put header files before C source for TAGS; remove
6296 references to non-existent syscalls.h.
6298 * read.c, write.c subsegs.c: back out the .bss changes.
6300 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6302 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6306 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6308 * symbols.c (local_label_name): symbols now start with ^A.
6310 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6311 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6312 generate these sections. .align: will use NOP_OPCODE or 0
6313 for padding. This is just for being nice to the
6316 * expr.c (operand): changed to generate local label "\001L0"
6317 starting with a ^A so that it is recognized as a local label.
6319 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6321 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6322 i/o opcodes - inb, inw, outb and outw. string manipulation with
6323 att syntax - scmp, slod, smov, ssca, ssto.
6325 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6326 to just after .file .
6328 In obj_crawl_symbol_chain() where it tries to put the external
6329 symbols apart, with the condition:
6330 (!S_IS_DEFINED(symbolP) &&
6331 !S_IS_DEBUG(symbolP) &&
6332 !SF_GET_STATICS(symbolP))
6333 it was moving too many symbols out. So I switch it back to the
6335 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6337 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6338 so that we don't use the F_RELFLG which make the linker complain
6339 that somebody has stripped the relocation info.
6341 Also, the AIX ld program require that the relocation table
6342 is sorted by r_vaddr like the standard ATT assembler does.
6344 [he also changed the sizeof(struct ...)'s into the coff
6345 style FOOSZ macros. I'm not sure this is right, but I can't
6346 remember why. xoxorich.]
6348 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6350 * Makefile.in, configure.in, doc: use the doc. Build it, install
6353 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6355 * read.c: white space and comments only.
6357 * configure.in: use the new atof-ns32.c for ns32k.
6359 * write.c: comment change only.
6361 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6362 aren't yet integrated.
6364 * tc-i860.[hc]: blew off the dust. Something must still be done
6365 about conflicting relocation types.
6367 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6370 * tc-i960.c, tc-sparc.c: white space and comments only.
6372 * tc-a29k.h: delete duplicate macro definition.
6374 * new file atof-ns32k.c copied from hack's last unreleased gas.
6376 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6378 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6381 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6382 ChangeLog's prior to this are sketchy at best. I have logs.
6383 They just aren't ChangeLogs.
6387 version-control: never
