1369 i386) as developmental. Deleted cases matching some generic names
1370 in favor of more specific names. (E.g., when we get Alpha

1398 Add comments to functions. Delete unused functions, variables,
1399 #defines, etc. Delete unused members within structures. Delete
1400 ldil;ble hacks -- it is believed they were installed to work
1401 around old gas bugs. Avoid using mixed case for local
1402 functions, variables, and structures. Fix formatting problems
1403 not found by GNU-indent. Add FIXME notices for things which
1404 should be worked on the near future. Delete lots of old
1405 useless (1.36 PA-SOM) code.

2548 * Extensive changes to permit symbols to contain any expression
2549 type and to delay the computation of the expression until the
2550 value is actually needed. This permits setting symbols to values
2551 calculated based on object code size. Expressions were changed to
2552 no longer be in a section, to stop the overloading of segment and
2553 expression type that previously occurred.
2555 * as.c (big_section, pass1_section, diff_section, absent_section):
2557 (expr_section): Added (used for dummy symbols which hold

2643 to pop back to it. Handle unquoted section name as well as quoted
2644 section name. Don't crash on invalid strings.

2757 sy_resolved and sy_resolving single bit fields.
2758 * symbols.c (symbol_new): Don't initialize sy_forward field.

3761 than ECOFF line number information.
3762 (obj_ecoff_stab): Accept non-zero values for stabs line number.

3794 * doc/as.texinfo: First pass at using new texinfo features --
3795 variables, conditional tests. Far from complete.

3823 dependencies are read, not when they are used).
3825 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
3826 a29k .bss section; the mondfe program doesn't like it.

3871 process relocs if there aren't any relocs to process. Avoids
3872 malloc/free bug on SCO too.

3875 avoid some redefinition complaints on some systems.
3876 (const, volatile): Don't need these conditionally defined if we
3877 use CONST and VOLATILE from ansidecl.h.
3878 (seg_name): Use CONST, not const.
3880 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3882 * config/tc-mips.c: Reindented to GNU standards.

3886 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3887 (fixup_segment): Add a29k special case; the linker is not prepared
3888 to see a segment offset here.

3893 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3895 * Makefile.in: add dvi target; as-$(config).texinfo might live in

3911 bignums, but don't emit error message.
3913 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3915 * Makefile.in (targ-cpu.o): Depend on config.h.
3917 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3919 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3920 dropping a space immediately following an identifier.
3921 * expr.c, write.c: Rewrote assert expressions to not use multiple
3922 lines; I don't think that can be done portably.
3923 * config/tc-mips.c (macro): Use $AT if target register is zero in
3924 load instruction, which it can be for a floating point load.
3926 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3947 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3949 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3950 to be on a single line.

3998 prototypes for all static functions. Moved existing minimal
3999 debugging format support info #ifndef OBJ_ECOFF blocks.

4002 all callers accordingly.
4003 (tc_get_register): Renamed from get_register, and made non-static.
4005 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4048 * make-gas.com: Find obstack.obj if it's not in the current
4050 * read.c (s_ignore): Don't declare is_end_of_line. It's
4051 redundant, and triggers a VMS gcc compiler bug.
4053 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4054 current segment as an argument. (Ignored in all cases but VMS.)
4055 All callers and definitions changed.

4352 md_relax_table): Use default zero initialization.
4353 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4354 latter, instead of selecting with preprocessor conditionals.
4356 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4358 * configure.in: recognise all sparclite variants

4368 * expr.c (operand): If character other than comma or newline is a
4369 logical end-of-line character, use the newline case.
4370 From Eric Youngdale:
4371 (operand): Set X_add_number field for floating-point numbers.
4372 (operand): Treat zero byte as end-of-operand.
4374 * configure.in (per-target): Look for with_bfd_assembler option.
4375 For now, only accept "no", until the merge is done.
4377 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4378 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4379 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4380 * read.c: Finish conversion to S_* macros in the VMS only
4381 parts of the program. Add "const" modifier to hex_value.

4384 * expr.c: Add "const" modifier to hex_value.
4385 * symbols.c: Finish conversion to S_* macros in the VMS only
4386 parts of the program. Add "const" modifier to
4387 md_[long,short]_jump_size. Remove declaration of const_flag
4388 (which will be declared in obj-vms.h).
4389 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4390 Fix arguments to VMS_write_object_file.
4391 * config-gas.com: New file. Script for VMS systems to set up the
4392 configuration to build gas for VMS, and create config.status.
4393 * make-gas.com: Redone to work with new scheme.
4394 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4396 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4397 will swap bytes if needed on a big endian system. Use throughout
4399 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4400 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4401 types of malformed stabs. Change parsing algorithm so that we are
4402 more certain of having all of the information that we need on hand.
4403 * obj-vms.c (final_forward_reference): New function, used to help
4404 resolve the data types of as many struct elements as possible
4405 when some part of the struct is not fully defined by the compiler.

4408 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4409 as symbols as well in the object file. Look for external functions
4410 that start with "__vt.", and turn them into variables, since the
4411 g++ compiler is incapable of doing this.
4412 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4414 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4415 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4416 have the name of the source file yet.
4417 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4419 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4421 * read.c (s_data): Always use "data_section", since it'll map to
4422 SEG_DATA or SEG_E1 if needed.
4423 (s_lcomm): Likewise with bss_section.
4424 (s_fill): Use memset, not bzero.
4426 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4447 (section_alignment): Declare only if not BFD_ASSEMBLER.
4448 (big_section, reg_section, pass1_section, diff_section,
4449 absent_section, text_section, data_section, bss_section): If
4450 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4451 mapping to segT enum values.
4452 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4453 if these are used or defined, if BFD_ASSEMBLER.
4454 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4455 subseg_new split into two functions.
4456 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4458 * as.h (volatile): Don't define if already defined.
4459 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4461 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4462 declare with format attribute for -Wformat checking.
4464 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4466 * app.c, config/tc-*.c: Don't include read.h, since it is already
4469 * These are based on patches from Minh Tran-le
4470 <mtranle@paris.intellicorp.com>.
4471 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4472 obj_format coffbfd and gas_target i386coff for target.
4473 (i[34]86-*-isc*): New host (uses sysv).
4474 * config/i386aix.mt: Removed (no longer used).
4475 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4477 (LDFLAGS): Added, defined as -shlib.
4478 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4479 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4480 (DOT_LABEL_PREFIX): Define.
4481 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4482 name rather than L0\001.
4483 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4485 * symbols.c, symbols.h (local_bss_counter): Removed.
4486 * write.c (write_object_file): bss no longer uses
4487 local_bss_counter. Pass correct data and bss size to
4488 VMS_write_object_file.

4494 (size_section): Restored sanity check.
4495 (do_relocs_for): Base section address on s_paddr rather than
4496 computing it. Adjust a29k R_IHIHALF special case to account for
4497 section paddr (used to require paddr to be zero). If there are no
4498 reclos, set s_relptr to 0. Set relocation size in object_headers.
4499 (fill_section): Always set s_vaddr here, removing
4500 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4501 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4502 Set STYP_INFO for .comment.
4503 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4504 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4506 H_{SET,GET}_* macros.
4507 (do_linenos_for): Set lineno size in object_headers.
4508 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4509 set s_vaddr here. If string_byte_count remains 4, set it back to
4510 0, and only write strings out if there are some. Call
4511 fill_section before do_relocs_for and do_linenos_for.
4512 (obj_coff_section): Handle optional quoted second argument giving
4513 section characteristics.
4514 (obj_coff_bss): Added to handle .bss.
4515 (obj_coff_ident): Added to handle .ident (puts string in .comment

4518 (fixup_mdeps): Change to segment. Call frag_wane after
4520 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4521 adjustment (already happened only for common symbols, but this is

4535 (do_scrub_next_char): For \", return " not '.
4536 (symbol_chars): Now const.
4538 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4539 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4541 * config/obj-coff.h: Don't use #elif.
4543 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4544 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4546 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4548 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4568 SEG_BSS, fill with NOP_OPCODE.
4569 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4570 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4571 using ZERO_BASED_SEGMENTS.
4572 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4573 never set segment address for SEG_E2 (.bss) and don't write out
4574 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4575 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4576 definitions, and don't merge tags with non-tags. Check for .bf
4577 rather than just checking whether the second character is b and
4578 the third character is f.
4579 (obj_coff_val): gcc can generate values which we don't handle
4580 correctly; discard information for now, since it only affects the
4581 debugging information.
4582 (tag_find_or_name): Don't insert tags in the symbol table.
4583 (yank_symbols): Don't merge labels.
4584 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4725 * configure.in: No te-386bsd.h file exists; don't try to use it.
4727 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
4729 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
4730 could be doing emulation.
4732 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4735 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4760 * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
4761 comment_chars, line_comment_chars and line_seperator_chars
4762 consistently const, and always initialized them. Included read.h.
4764 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4766 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4767 constant will not fit in an immediate field.
4768 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
4770 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
4772 * obj-coff.c (callj_table): Delete global variable.

4779 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
4780 with a single set using PARAMS macro.
4782 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length

4787 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
4788 so widening works consistently.
4790 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
4792 * version.c: Put conditional "const" before version_string, not
4793 before dummy function for VMS. Now version 1.91.03.
4795 * app.c (do_scrub_next_char): Need double-\ before `000' to show
4796 printed rep of null character.
4798 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
4800 * obj-coffbfd.c (write_object_file): check return value of
4803 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4805 * Support for i386-sysv.
4806 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
4807 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
4808 be used to set them all to zero as was done before.
4809 (fill_section): segment addresses now set in write_object_file.
4810 (fill_section): Don't set STYP_NOLOAD for .bss section.
4811 (fixup_segment): 386 uses strange common symbol format.
4812 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
4813 compatibility with SVR3.2 linker.
4814 * configure.in: i386-sysv and i386-sco use coffbfd.
4816 * app.c (do_scrub_next_char): discard whitespace after a label.

4825 fix i960+non-bfd coff bit rot.
4826 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
4827 support for C source listings. (obj_coff_endef): look in the right

4830 * tc-m68k.c (get_num): make it work for all segments, not just the
4833 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
4835 * configure.in: recognize i386-*-bsd emulation.

4844 * tc-z8k.c: lots of bug fixes
4846 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4848 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4849 #elif, since it is not supported by old compilers.
4850 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4851 couple of expressions in tc-m68k.c.
4853 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4855 * read.c (cons): If NO_RELOC is defined, use it.
4857 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4859 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4861 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4862 local labels to start with a .) and set REGISTER_PREFIX to %.
4863 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4865 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4879 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4881 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4882 sections starting from zero, rather than making them consecutive.
4883 This makes subsequent reloc calculations easier, esp if the object
4884 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4885 allocate lcomm in .data rather than in .bss. It seems that some
4886 tools can't cope with a non-zero sized bss before linkage.
4888 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4890 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
4891 throughout. That enum no longer means what we thought it meant.

4905 Change LIBDEPS dependence to LIBS.
4907 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4909 * Makefile.in (install): if $(tooldir) exists, install as in
4912 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4914 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4915 .word is < -32768 or > 32767. The -J flag causes the error to be
4916 ignored. This is to catch over-sized switches generated by gcc on
4917 systems which don't support the broken .word hack.
4918 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4919 write.c (fixup_segment): check for signed .word overflow if
4920 WARN_SIGNED_OVERFLOW_WORD.
4922 * write.c (fixup_segment): fixed missing parens in expression
4923 checking for byte or word overflow.
4925 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
4926 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
4927 WARN_SIGNED_OVERFLOW_WORD.

4935 * obj-coffbfd.h : added stuff
4936 * tc-i386.c (tc_coff_fix2rtype): new function
4937 * tc-i386.h : new coff defines
4939 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4941 * input-scrub.c (input_scrub_push): call input_file_begin, not
4943 messages.c (as_perror): print ": " between the passed in error and
4944 the strerror, like perror does.
4946 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
4948 * Makefile.in: use gas_target instead of modifying target_cpu.
4949 From Steve Chamberlain:
4950 Makefile.in: Handle m68*-*-coff*.
4951 read.c, read.h: add mult argument to s_space
4953 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4954 Motorola and MIT syntax; gas can now assemble either type of
4956 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
4957 From Steve Chamberlain:
4958 m68kcoff.mt: for m68k COFF.
4959 obj-coffbfd.c: (fixup_mdeps) added

4962 (write_object_file) call fixup_mdeps
4963 (fixup_segment) set fx_subsy to 0.
4964 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4966 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4969 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4971 * Makefile.in (LIBS): Include opcode library.
4973 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

4993 tc-i960.c (md_ri_to_chars): Always output bout object file in
4994 little endian byte order (used to use endianness of host).
4996 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4998 * config/tc-m68k.c (init_table): Now const. Always include 68851
4999 data, so that "bc" is available to 68040 cache instructions.
5000 Added "tt0", "tt1", and 68ec030 variants.
5001 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5002 (enum _register): Added TT0, TT1.
5003 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5004 line number correctly in "internal error" messages. Don't print
5005 architecture-mismatch message for operand errors.
5007 From Colin Smith (colin@wrs.com):
5008 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5009 than install_operand.

5013 * listing.c (buffer_line): rewind to the start of include
5014 files, they might be included twice.

5023 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5025 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5026 so that we can assemble hand-written libgcc code.
5028 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5030 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5031 has already been formatted (but may still contain %-characters).
5034 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5036 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5037 written with indirection on the last two operands, which can be
5038 either data or address registers. Added a new operand type 'r'
5039 which accepts either register type. Added '(' to notend stuff in
5040 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5042 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

5056 (relax_align): If linkrelax, provide extra padding.
5058 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5059 their not having symbols associated.
5061 * tc-i960.c (norelax, instrument_branches): Default initializer is
5063 (linkrelax): Delete variable definition.

5086 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
5087 being used with args swapped, causing occasional lossage when
5088 refilling buffers after an include file.
5090 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5092 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
5093 version. Discard bogus DONTDEF version.
5094 (as_warn, as_bad, as_fatal): Likewise.
5096 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
5098 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5099 selected architecture, print a message saying so and listing what

5144 * configure.in (mips host): Accept "ultrix" with version number.
5146 * expr.c (floating_constant): Separate "=-" to avoid confusing
5147 ancient or broken compilers.
5149 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5150 processor/opcode mismatch, so reword the error message.
5151 (md_assemble): If no CPU has been set (even if FPU/PMMU
5152 characteristics have been), default to 68020. Don't need extra
5153 quotes around error string.
5155 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5157 * read.c (potable): Revert sac's incorrect change made Jul 13.

5227 * write.c (write_object_file): If a.out don't use the old way for
5229 * config/obj-a.out (s_sect): complain if the user tries to use a
5230 subsegment with a value which might interfere with out -R hackery.
5231 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
5232 rather than use ugly if tree. (init_regtable): insert register
5233 names into symbol table.
5235 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5237 * write.c (write_object_file): keep the fix_tail clean, which
5238 fixes a bug in -R where relocations were being lost.
5240 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5242 * configure.in: recognize m680x0 as having sun3 emulation mode for

5265 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5267 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
5268 calc the base of relocs correctly.
5269 * tc-a29k.c (parse_operand): allow expressions to be in any section.
5271 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
5273 * as.c, write.c: use -K rather than -k for the broken word warning

5284 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5286 * write.c (write_object_file): For b.out format, round up section
5287 start addresses to match required alignment.
5289 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5291 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5292 where gcc looks for it.
5294 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5296 * Makefile.in: Changed some lines to be less confusing for some
5299 * input-file.c: Conditionalize on _IOFBF, not VMS.
5301 * read.c, write.c: Change a series of ifdef/elif to

5324 tc-m68k.h to te-sun3.h.
5326 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
5328 * configure.in: vxworks68 gets te-sun3.h.

5336 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
5338 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

5359 * Makefile.in (strerror.o): Add rule so that broken Sun make can
5362 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5364 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5366 * expr.c (operand): if can't work out what sort of operand it is,
5367 then look through FLT_CHARS for a hint.
5369 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5371 * Makefile.in, configure.in: removed traces of namesubdir,
5372 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5373 copyrights to '92, changed some from Cygnus to FSF.
5375 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5376 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5377 copyrights to '92, changed some from Cygnus to FSF.
5379 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5381 * expr.c: If an expression is single comma, then return with
5382 SEG_ABSENT rather than an error - since the sparc front end does
5383 really strange things with things like fbge,a
5385 * as.h: include bfd.h if using many sections
5386 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5387 local labels didn't work.
5388 * listing.c (list_symbol_table): don't core dump when there's no
5390 * write.c, write.h: call fix_new with the right number of args on
5392 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5395 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5397 * app.c: MRI compatibility - allow single quote to start a string.
5398 * as.c: fix typo recently introduced.
5399 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5400 * expr.c: Much rewriting, to accomodate MRI syntax for
5401 expressions. Also easier to read now.
5402 * listing.c: Put back defuns
5403 * read.c: modified to accept MRI syntax, put back listing pseudo
5404 ops so that an assembler built with NO_LISTING ignores list ops
5406 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5407 machine is a SPARC or a 29K.
5408 * config/obj-aout.c: added s_sect pseudo op
5409 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5410 fill in the timestamp.
5411 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5412 anymore, define all the relocs which the tc-<x> bit will use so we
5413 can translate from them to the coff types.
5414 * config/tc-a29k.c: reloc_type isn't ane enum any more
5415 * config/tc-m68k.c: Added NO_RELOC definition.
5417 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5419 * Makefile.in: put header files before C source for TAGS; remove
5420 references to non-existent syscalls.h.
5422 * read.c, write.c subsegs.c: back out the .bss changes.
5424 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5426 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5430 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5432 * symbols.c (local_label_name): symbols now start with ^A.
5434 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5435 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5436 generate these sections. .align: will use NOP_OPCODE or 0
5437 for padding. This is just for being nice to the
5440 * expr.c (operand): changed to generate local label "\001L0"
5441 starting with a ^A so that it is recognized as a local label.
5443 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5445 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5446 i/o opcodes - inb, inw, outb and outw. string manipulation with
5447 att syntax - scmp, slod, smov, ssca, ssto.
5449 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5450 to just after .file .
5452 In obj_crawl_symbol_chain() where it tries to put the external
5453 symbols apart, with the condition:
5454 (!S_IS_DEFINED(symbolP) &&
5455 !S_IS_DEBUG(symbolP) &&
5456 !SF_GET_STATICS(symbolP))
5457 it was moving too many symbols out. So I switch it back to the
5459 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5461 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5462 so that we don't use the F_RELFLG which make the linker complain
5463 that somebody has stripped the relocation info.
5465 Also, the AIX ld program require that the relocation table
5466 is sorted by r_vaddr like the standard ATT assembler does.
5468 [he also changed the sizeof(struct ...)'s into the coff
5469 style FOOSZ macros. I'm not sure this is right, but I can't
5470 remember why. xoxorich.]
5472 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5474 * Makefile.in, configure.in, doc: use the doc. Build it, install
5477 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5479 * read.c: white space and comments only.
5481 * configure.in: use the new atof-ns32.c for ns32k.
5483 * write.c: comment change only.
5485 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5486 aren't yet integrated.
5488 * tc-i860.[hc]: blew off the dust. Something must still be done
5489 about conflicting relocation types.
5491 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5494 * tc-i960.c, tc-sparc.c: white space and comments only.
5496 * tc-a29k.h: delete duplicate macro definition.
5498 * new file atof-ns32k.c copied from hack's last unreleased gas.
5500 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5502 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5505 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5506 ChangeLog's prior to this are sketchy at best. I have logs.
5507 They just aren't ChangeLogs.
