1692 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1693 the table, require that the one without bit 0x1000000 set come

1748 * write.c (write_relocs): For relocs that are pc_relative and
1749 pcrel_offset and not partial_inplace, adjust reloc->addend to

1805 for keeping or rejecting configurations still under development;
1806 default is to assume production environment, and reject configs
1807 still being worked on. Mark Elf configurations (except sparc and
1808 i386) as developmental. Deleted cases matching some generic names
1809 in favor of more specific names. (E.g., when we get Alpha
1810 support, we'll still only support VMS for Vax.)

1826 through inclusion of tc-hppa.h. Delete all forward declarations
1827 for functions only used within tc-hppa.c, likewise for structures,
1828 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1829 conditional code in a few small places.
1831 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1832 structures, global variables, forward declarations together.

1834 conditional code -- try to group conditional code together
1835 into a few places. Make all functions and variables which
1836 are only used within tc-hppa.c static. PARAMize all functions.
1837 Add comments to functions. Delete unused functions, variables,
1838 #defines, etc. Delete unused members within structures. Delete
1839 ldil;ble hacks -- it is believed they were installed to work
1840 around old gas bugs. Avoid using mixed case for local
1841 functions, variables, and structures. Fix formatting problems
1842 not found by GNU-indent. Add FIXME notices for things which
1843 should be worked on the near future. Delete lots of old
1844 useless (1.36 PA-SOM) code.
1846 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
1847 field of the fixS structure. Needed to build unwind

1873 a multiple of the section alignment rather than always a
1876 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
1877 bits are zero (eg they specify no relocations), then do not even
1878 bother adding their entries to thesymextn section.

1913 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
1914 call strchr for each character to see if it is a special char,
1915 instead add a second loop over special_chars. Set alignment
1916 of text, data and bss sections to 4.
1917 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1919 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1920 ELF, since the ELF object format does not have these type of
1921 relocations. Change the abort into as as_bad and return
1922 BFD_RELOC_NONE to silence compiler warnings.
1923 (md_assemble): Keep track of the instruction size. Allow white

2873 Thu Jul 29 18:38:37 1993 david d `zoo' zuhn (zoo@rtl.cygnus.com)
2875 * config/ho-sunos.h: remove some old function decls that conflict
2876 w/ ANSI, and which weren't needed anyway

2922 are also magic, and have special default flag settings.
2923 (obj_elf_frob_symbol): Since the return value from this function

2987 * Extensive changes to permit symbols to contain any expression
2988 type and to delay the computation of the expression until the
2989 value is actually needed. This permits setting symbols to values
2990 calculated based on object code size. Expressions were changed to
2991 no longer be in a section, to stop the overloading of segment and
2992 expression type that previously occurred.
2994 * as.c (big_section, pass1_section, diff_section, absent_section):
2996 (expr_section): Added (used for dummy symbols which hold

3083 section name. Don't crash on invalid strings.
3084 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

3196 sy_resolved and sy_resolving single bit fields.
3197 * symbols.c (symbol_new): Don't initialize sy_forward field.

4228 references don't appear to work right.
4230 * as.h (const, volatile): Put these definitions back, and use
4233 * doc/as.texinfo: First pass at using new texinfo features --
4234 variables, conditional tests. Far from complete.

4262 dependencies are read, not when they are used).
4264 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4265 a29k .bss section; the mondfe program doesn't like it.

4286 source directory, if that's not the current directory.
4288 * configure.in (per-host): Accept MIPS host with BSD version

4310 process relocs if there aren't any relocs to process. Avoids
4311 malloc/free bug on SCO too.

4314 avoid some redefinition complaints on some systems.
4315 (const, volatile): Don't need these conditionally defined if we
4316 use CONST and VOLATILE from ansidecl.h.
4317 (seg_name): Use CONST, not const.
4319 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4321 * config/tc-mips.c: Reindented to GNU standards.

4325 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4326 (fixup_segment): Add a29k special case; the linker is not prepared
4327 to see a segment offset here.
4329 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4332 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4334 * Makefile.in: add dvi target; as-$(config).texinfo might live in

4350 bignums, but don't emit error message.
4352 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
4354 * Makefile.in (targ-cpu.o): Depend on config.h.
4356 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4358 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4359 dropping a space immediately following an identifier.
4360 * expr.c, write.c: Rewrote assert expressions to not use multiple
4361 lines; I don't think that can be done portably.
4362 * config/tc-mips.c (macro): Use $AT if target register is zero in
4363 load instruction, which it can be for a floating point load.
4365 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
4367 * write.c (write_contents): Compute the relocs before writing out

4386 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4388 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4389 to be on a single line.
4391 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4393 * Makefile.in (config.h): Create file, writing out definitions of

4436 * config/tc-mips.c: Rearranged for ECOFF support. Added
4437 prototypes for all static functions. Moved existing minimal
4438 debugging format support info #ifndef OBJ_ECOFF blocks.

4441 all callers accordingly.
4442 (tc_get_register): Renamed from get_register, and made non-static.
4444 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4487 * make-gas.com: Find obstack.obj if it's not in the current
4489 * read.c (s_ignore): Don't declare is_end_of_line. It's
4490 redundant, and triggers a VMS gcc compiler bug.
4492 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4493 current segment as an argument. (Ignored in all cases but VMS.)
4494 All callers and definitions changed.

4790 * config/tc-sparc.c (architecture_requested, warn_on_bump,
4791 md_relax_table): Use default zero initialization.
4792 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4793 latter, instead of selecting with preprocessor conditionals.
4795 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4797 * configure.in: recognise all sparclite variants
4799 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

4805 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4807 * expr.c (operand): If character other than comma or newline is a
4808 logical end-of-line character, use the newline case.
4809 From Eric Youngdale:
4810 (operand): Set X_add_number field for floating-point numbers.
4811 (operand): Treat zero byte as end-of-operand.
4813 * configure.in (per-target): Look for with_bfd_assembler option.
4814 For now, only accept "no", until the merge is done.
4816 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4817 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4818 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4819 * read.c: Finish conversion to S_* macros in the VMS only
4820 parts of the program. Add "const" modifier to hex_value.
4821 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4823 * expr.c: Add "const" modifier to hex_value.
4824 * symbols.c: Finish conversion to S_* macros in the VMS only
4825 parts of the program. Add "const" modifier to
4826 md_[long,short]_jump_size. Remove declaration of const_flag
4827 (which will be declared in obj-vms.h).
4828 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4829 Fix arguments to VMS_write_object_file.
4830 * config-gas.com: New file. Script for VMS systems to set up the
4831 configuration to build gas for VMS, and create config.status.
4832 * make-gas.com: Redone to work with new scheme.
4833 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4835 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4836 will swap bytes if needed on a big endian system. Use throughout
4838 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4839 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4840 types of malformed stabs. Change parsing algorithm so that we are
4841 more certain of having all of the information that we need on hand.
4842 * obj-vms.c (final_forward_reference): New function, used to help
4843 resolve the data types of as many struct elements as possible
4844 when some part of the struct is not fully defined by the compiler.
4845 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
4847 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4848 as symbols as well in the object file. Look for external functions
4849 that start with "__vt.", and turn them into variables, since the
4850 g++ compiler is incapable of doing this.
4851 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4853 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4854 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4855 have the name of the source file yet.
4856 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4858 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4860 * read.c (s_data): Always use "data_section", since it'll map to
4861 SEG_DATA or SEG_E1 if needed.
4862 (s_lcomm): Likewise with bss_section.
4863 (s_fill): Use memset, not bzero.
4865 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4886 (section_alignment): Declare only if not BFD_ASSEMBLER.
4887 (big_section, reg_section, pass1_section, diff_section,
4888 absent_section, text_section, data_section, bss_section): If
4889 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4890 mapping to segT enum values.
4891 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4892 if these are used or defined, if BFD_ASSEMBLER.
4893 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4894 subseg_new split into two functions.
4895 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4897 * as.h (volatile): Don't define if already defined.
4898 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4900 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4901 declare with format attribute for -Wformat checking.
4903 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4905 * app.c, config/tc-*.c: Don't include read.h, since it is already
4908 * These are based on patches from Minh Tran-le
4909 <mtranle@paris.intellicorp.com>.
4910 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4911 obj_format coffbfd and gas_target i386coff for target.
4912 (i[34]86-*-isc*): New host (uses sysv).
4913 * config/i386aix.mt: Removed (no longer used).
4914 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4916 (LDFLAGS): Added, defined as -shlib.
4917 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4918 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4919 (DOT_LABEL_PREFIX): Define.
4920 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4921 name rather than L0\001.
4922 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4924 * symbols.c, symbols.h (local_bss_counter): Removed.
4925 * write.c (write_object_file): bss no longer uses
4926 local_bss_counter. Pass correct data and bss size to
4927 VMS_write_object_file.

4933 (size_section): Restored sanity check.
4934 (do_relocs_for): Base section address on s_paddr rather than
4935 computing it. Adjust a29k R_IHIHALF special case to account for
4936 section paddr (used to require paddr to be zero). If there are no
4937 reclos, set s_relptr to 0. Set relocation size in object_headers.
4938 (fill_section): Always set s_vaddr here, removing
4939 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4940 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4941 Set STYP_INFO for .comment.
4942 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4943 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4945 H_{SET,GET}_* macros.
4946 (do_linenos_for): Set lineno size in object_headers.
4947 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4948 set s_vaddr here. If string_byte_count remains 4, set it back to
4949 0, and only write strings out if there are some. Call
4950 fill_section before do_relocs_for and do_linenos_for.
4951 (obj_coff_section): Handle optional quoted second argument giving
4952 section characteristics.
4953 (obj_coff_bss): Added to handle .bss.
4954 (obj_coff_ident): Added to handle .ident (puts string in .comment

4974 (do_scrub_next_char): For \", return " not '.
4975 (symbol_chars): Now const.
4977 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4978 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4980 * config/obj-coff.h: Don't use #elif.
4982 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4983 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5009 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5010 using ZERO_BASED_SEGMENTS.
5011 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5012 never set segment address for SEG_E2 (.bss) and don't write out
5013 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5014 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5015 definitions, and don't merge tags with non-tags. Check for .bf
5016 rather than just checking whether the second character is b and
5017 the third character is f.
5018 (obj_coff_val): gcc can generate values which we don't handle
5019 correctly; discard information for now, since it only affects the
5020 debugging information.

5022 (yank_symbols): Don't merge labels.
5023 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5201 consistently const, and always initialized them. Included read.h.
5203 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5205 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5206 constant will not fit in an immediate field.
5207 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
5209 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

5226 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
5227 so widening works consistently.
5229 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
5231 * version.c: Put conditional "const" before version_string, not

5234 * app.c (do_scrub_next_char): Need double-\ before `000' to show
5235 printed rep of null character.
5237 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
5239 * obj-coffbfd.c (write_object_file): check return value of
5242 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5244 * Support for i386-sysv.
5245 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
5246 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
5247 be used to set them all to zero as was done before.

5249 (fill_section): Don't set STYP_NOLOAD for .bss section.
5250 (fixup_segment): 386 uses strange common symbol format.

5269 * tc-m68k.c (get_num): make it work for all segments, not just the
5272 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

5283 * tc-z8k.c: lots of bug fixes
5285 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5287 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5288 #elif, since it is not supported by old compilers.
5289 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5290 couple of expressions in tc-m68k.c.
5292 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5294 * read.c (cons): If NO_RELOC is defined, use it.
5296 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5298 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5300 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5301 local labels to start with a .) and set REGISTER_PREFIX to %.
5302 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

5320 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5321 sections starting from zero, rather than making them consecutive.
5322 This makes subsequent reloc calculations easier, esp if the object
5323 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5324 allocate lcomm in .data rather than in .bss. It seems that some
5325 tools can't cope with a non-zero sized bss before linkage.
5327 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5329 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5348 * Makefile.in (install): if $(tooldir) exists, install as in
5351 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5353 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5354 .word is < -32768 or > 32767. The -J flag causes the error to be
5355 ignored. This is to catch over-sized switches generated by gcc on
5356 systems which don't support the broken .word hack.
5357 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5358 write.c (fixup_segment): check for signed .word overflow if
5359 WARN_SIGNED_OVERFLOW_WORD.

5378 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5380 * input-scrub.c (input_scrub_push): call input_file_begin, not
5382 messages.c (as_perror): print ": " between the passed in error and
5383 the strerror, like perror does.

5388 From Steve Chamberlain:
5389 Makefile.in: Handle m68*-*-coff*.
5390 read.c, read.h: add mult argument to s_space
5392 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5393 Motorola and MIT syntax; gas can now assemble either type of
5395 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5403 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5405 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5408 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5410 * Makefile.in (LIBS): Include opcode library.

5435 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5437 * config/tc-m68k.c (init_table): Now const. Always include 68851
5438 data, so that "bc" is available to 68040 cache instructions.
5439 Added "tt0", "tt1", and 68ec030 variants.
5440 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5441 (enum _register): Added TT0, TT1.
5442 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5443 line number correctly in "internal error" messages. Don't print
5444 architecture-mismatch message for operand errors.
5446 From Colin Smith (colin@wrs.com):
5447 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5448 than install_operand.

5469 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5470 has already been formatted (but may still contain %-characters).
5473 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5475 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5476 written with indirection on the last two operands, which can be
5477 either data or address registers. Added a new operand type 'r'
5478 which accepts either register type. Added '(' to notend stuff in
5479 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5498 their not having symbols associated.
5500 * tc-i960.c (norelax, instrument_branches): Default initializer is

5526 being used with args swapped, causing occasional lossage when
5527 refilling buffers after an include file.

5585 * expr.c (floating_constant): Separate "=-" to avoid confusing
5586 ancient or broken compilers.
5588 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5589 processor/opcode mismatch, so reword the error message.
5590 (md_assemble): If no CPU has been set (even if FPU/PMMU
5591 characteristics have been), default to 68020. Don't need extra
5592 quotes around error string.

5677 fixes a bug in -R where relocations were being lost.
5679 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5681 * configure.in: recognize m680x0 as having sun3 emulation mode for
5682 vxworks environment.

5704 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5706 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
5707 calc the base of relocs correctly.
5708 * tc-a29k.c (parse_operand): allow expressions to be in any section.
5710 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
5712 * as.c, write.c: use -K rather than -k for the broken word warning
5715 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
5717 * Makefile.in: do not print recursion lines.
5719 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)

5723 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5725 * write.c (write_object_file): For b.out format, round up section
5726 start addresses to match required alignment.
5728 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5730 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5731 where gcc looks for it.
5733 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5735 * Makefile.in: Changed some lines to be less confusing for some
5738 * input-file.c: Conditionalize on _IOFBF, not VMS.
5740 * read.c, write.c: Change a series of ifdef/elif to
5741 ifdef/else/ifdef etc.

5755 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5757 * flonum-const.c: renamed flonum-konst.c to stop dos name
5760 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
5762 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
5763 tc-m68k.h to te-sun3.h.
5765 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
5767 * configure.in: vxworks68 gets te-sun3.h.
5769 * expr.c: remove limitation that local_labels_dollar or
5770 local_labels_fb must be < 10.
5772 * symbols.c: remove local_labels_dollar, replace with a function
5773 interface for a sparse array. All users adjusted.
5775 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
5777 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5779 * doc/Makefile.in: commented out line for building as-all.texinfo.
5782 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
5784 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

5796 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
5798 * Makefile.in (strerror.o): Add rule so that broken Sun make can
5801 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5803 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5805 * expr.c (operand): if can't work out what sort of operand it is,
5806 then look through FLT_CHARS for a hint.
5808 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5810 * Makefile.in, configure.in: removed traces of namesubdir,
5811 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5812 copyrights to '92, changed some from Cygnus to FSF.
5814 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5815 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5816 copyrights to '92, changed some from Cygnus to FSF.
5818 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5820 * expr.c: If an expression is single comma, then return with
5821 SEG_ABSENT rather than an error - since the sparc front end does
5822 really strange things with things like fbge,a
5824 * as.h: include bfd.h if using many sections
5825 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5826 local labels didn't work.
5827 * listing.c (list_symbol_table): don't core dump when there's no
5829 * write.c, write.h: call fix_new with the right number of args on
5831 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5834 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5836 * app.c: MRI compatibility - allow single quote to start a string.
5837 * as.c: fix typo recently introduced.
5838 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5839 * expr.c: Much rewriting, to accomodate MRI syntax for
5840 expressions. Also easier to read now.
5841 * listing.c: Put back defuns
5842 * read.c: modified to accept MRI syntax, put back listing pseudo
5843 ops so that an assembler built with NO_LISTING ignores list ops
5845 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5846 machine is a SPARC or a 29K.
5847 * config/obj-aout.c: added s_sect pseudo op
5848 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5849 fill in the timestamp.
5850 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5851 anymore, define all the relocs which the tc-<x> bit will use so we
5852 can translate from them to the coff types.
5853 * config/tc-a29k.c: reloc_type isn't ane enum any more
5854 * config/tc-m68k.c: Added NO_RELOC definition.
5856 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5858 * Makefile.in: put header files before C source for TAGS; remove
5859 references to non-existent syscalls.h.
5861 * read.c, write.c subsegs.c: back out the .bss changes.
5863 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5865 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5869 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5871 * symbols.c (local_label_name): symbols now start with ^A.
5873 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5874 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5875 generate these sections. .align: will use NOP_OPCODE or 0
5876 for padding. This is just for being nice to the
5879 * expr.c (operand): changed to generate local label "\001L0"
5880 starting with a ^A so that it is recognized as a local label.
5882 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5884 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5885 i/o opcodes - inb, inw, outb and outw. string manipulation with
5886 att syntax - scmp, slod, smov, ssca, ssto.
5888 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5889 to just after .file .
5891 In obj_crawl_symbol_chain() where it tries to put the external
5892 symbols apart, with the condition:
5893 (!S_IS_DEFINED(symbolP) &&
5894 !S_IS_DEBUG(symbolP) &&
5895 !SF_GET_STATICS(symbolP))
5896 it was moving too many symbols out. So I switch it back to the
5898 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5900 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5901 so that we don't use the F_RELFLG which make the linker complain
5902 that somebody has stripped the relocation info.
5904 Also, the AIX ld program require that the relocation table
5905 is sorted by r_vaddr like the standard ATT assembler does.
5907 [he also changed the sizeof(struct ...)'s into the coff
5908 style FOOSZ macros. I'm not sure this is right, but I can't
5909 remember why. xoxorich.]
5911 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5913 * Makefile.in, configure.in, doc: use the doc. Build it, install
5916 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5918 * read.c: white space and comments only.
5920 * configure.in: use the new atof-ns32.c for ns32k.
5922 * write.c: comment change only.
5924 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5925 aren't yet integrated.
5927 * tc-i860.[hc]: blew off the dust. Something must still be done
5928 about conflicting relocation types.
5930 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5933 * tc-i960.c, tc-sparc.c: white space and comments only.
5935 * tc-a29k.h: delete duplicate macro definition.
5937 * new file atof-ns32k.c copied from hack's last unreleased gas.
5939 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5941 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5944 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5945 ChangeLog's prior to this are sketchy at best. I have logs.
5946 They just aren't ChangeLogs.
