1686 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1687 the table, require that the one without bit 0x1000000 set come

1742 * write.c (write_relocs): For relocs that are pc_relative and
1743 pcrel_offset and not partial_inplace, adjust reloc->addend to

1799 for keeping or rejecting configurations still under development;
1800 default is to assume production environment, and reject configs
1801 still being worked on. Mark Elf configurations (except sparc and
1802 i386) as developmental. Deleted cases matching some generic names
1803 in favor of more specific names. (E.g., when we get Alpha
1804 support, we'll still only support VMS for Vax.)

1820 through inclusion of tc-hppa.h. Delete all forward declarations
1821 for functions only used within tc-hppa.c, likewise for structures,
1822 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1823 conditional code in a few small places.
1825 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1826 structures, global variables, forward declarations together.

1828 conditional code -- try to group conditional code together
1829 into a few places. Make all functions and variables which
1830 are only used within tc-hppa.c static. PARAMize all functions.
1831 Add comments to functions. Delete unused functions, variables,
1832 #defines, etc. Delete unused members within structures. Delete
1833 ldil;ble hacks -- it is believed they were installed to work
1834 around old gas bugs. Avoid using mixed case for local
1835 functions, variables, and structures. Fix formatting problems
1836 not found by GNU-indent. Add FIXME notices for things which
1837 should be worked on the near future. Delete lots of old
1838 useless (1.36 PA-SOM) code.
1840 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
1841 field of the fixS structure. Needed to build unwind

1867 a multiple of the section alignment rather than always a
1870 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
1871 bits are zero (eg they specify no relocations), then do not even
1872 bother adding their entries to thesymextn section.

1907 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
1908 call strchr for each character to see if it is a special char,

1910 of text, data and bss sections to 4.
1911 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1913 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1914 ELF, since the ELF object format does not have these type of
1915 relocations. Change the abort into as as_bad and return
1916 BFD_RELOC_NONE to silence compiler warnings.
1917 (md_assemble): Keep track of the instruction size. Allow white
1918 space between the $ and the constant for compatibility with older
1919 gases and other assemblers.
1920 (i386_operand): Skip spaces between $ and expression.

2916 are also magic, and have special default flag settings.
2917 (obj_elf_frob_symbol): Since the return value from this function

2981 * Extensive changes to permit symbols to contain any expression
2982 type and to delay the computation of the expression until the
2983 value is actually needed. This permits setting symbols to values
2984 calculated based on object code size. Expressions were changed to
2985 no longer be in a section, to stop the overloading of segment and
2986 expression type that previously occurred.
2988 * as.c (big_section, pass1_section, diff_section, absent_section):
2990 (expr_section): Added (used for dummy symbols which hold

4256 dependencies are read, not when they are used).
4258 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4259 a29k .bss section; the mondfe program doesn't like it.

4280 source directory, if that's not the current directory.
4282 * configure.in (per-host): Accept MIPS host with BSD version

4304 process relocs if there aren't any relocs to process. Avoids
4305 malloc/free bug on SCO too.

4308 avoid some redefinition complaints on some systems.
4309 (const, volatile): Don't need these conditionally defined if we
4310 use CONST and VOLATILE from ansidecl.h.
4311 (seg_name): Use CONST, not const.
4313 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4315 * config/tc-mips.c: Reindented to GNU standards.

4319 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4320 (fixup_segment): Add a29k special case; the linker is not prepared
4321 to see a segment offset here.
4323 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4326 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4328 * Makefile.in: add dvi target; as-$(config).texinfo might live in

4344 bignums, but don't emit error message.
4346 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
4348 * Makefile.in (targ-cpu.o): Depend on config.h.
4350 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4352 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4353 dropping a space immediately following an identifier.
4354 * expr.c, write.c: Rewrote assert expressions to not use multiple
4355 lines; I don't think that can be done portably.
4356 * config/tc-mips.c (macro): Use $AT if target register is zero in
4357 load instruction, which it can be for a floating point load.
4359 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4380 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4382 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4383 to be on a single line.
4385 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4387 * Makefile.in (config.h): Create file, writing out definitions of

4430 * config/tc-mips.c: Rearranged for ECOFF support. Added
4431 prototypes for all static functions. Moved existing minimal
4432 debugging format support info #ifndef OBJ_ECOFF blocks.

4434 does not support a non sign extended high 16 bits reloc. Adjusted
4435 all callers accordingly.
4436 (tc_get_register): Renamed from get_register, and made non-static.
4438 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4481 * make-gas.com: Find obstack.obj if it's not in the current
4483 * read.c (s_ignore): Don't declare is_end_of_line. It's
4484 redundant, and triggers a VMS gcc compiler bug.
4486 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4487 current segment as an argument. (Ignored in all cases but VMS.)
4488 All callers and definitions changed.

4784 * config/tc-sparc.c (architecture_requested, warn_on_bump,
4785 md_relax_table): Use default zero initialization.
4786 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4787 latter, instead of selecting with preprocessor conditionals.
4789 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4791 * configure.in: recognise all sparclite variants
4793 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

4796 accidentally changed to use subseg_change where it should have
4799 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4801 * expr.c (operand): If character other than comma or newline is a
4802 logical end-of-line character, use the newline case.
4803 From Eric Youngdale:
4804 (operand): Set X_add_number field for floating-point numbers.
4805 (operand): Treat zero byte as end-of-operand.
4807 * configure.in (per-target): Look for with_bfd_assembler option.
4808 For now, only accept "no", until the merge is done.
4810 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4811 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4812 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4813 * read.c: Finish conversion to S_* macros in the VMS only
4814 parts of the program. Add "const" modifier to hex_value.
4815 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4817 * expr.c: Add "const" modifier to hex_value.
4818 * symbols.c: Finish conversion to S_* macros in the VMS only
4819 parts of the program. Add "const" modifier to
4820 md_[long,short]_jump_size. Remove declaration of const_flag
4821 (which will be declared in obj-vms.h).
4822 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4823 Fix arguments to VMS_write_object_file.
4824 * config-gas.com: New file. Script for VMS systems to set up the
4825 configuration to build gas for VMS, and create config.status.
4826 * make-gas.com: Redone to work with new scheme.
4827 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4829 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4830 will swap bytes if needed on a big endian system. Use throughout
4832 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4833 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4834 types of malformed stabs. Change parsing algorithm so that we are
4835 more certain of having all of the information that we need on hand.
4836 * obj-vms.c (final_forward_reference): New function, used to help
4837 resolve the data types of as many struct elements as possible
4838 when some part of the struct is not fully defined by the compiler.
4839 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
4841 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4842 as symbols as well in the object file. Look for external functions
4843 that start with "__vt.", and turn them into variables, since the
4844 g++ compiler is incapable of doing this.
4845 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4847 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4848 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4849 have the name of the source file yet.
4850 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4852 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4854 * read.c (s_data): Always use "data_section", since it'll map to
4855 SEG_DATA or SEG_E1 if needed.
4856 (s_lcomm): Likewise with bss_section.
4857 (s_fill): Use memset, not bzero.
4859 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4880 (section_alignment): Declare only if not BFD_ASSEMBLER.
4881 (big_section, reg_section, pass1_section, diff_section,
4882 absent_section, text_section, data_section, bss_section): If
4883 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4884 mapping to segT enum values.
4885 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4886 if these are used or defined, if BFD_ASSEMBLER.
4887 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4888 subseg_new split into two functions.
4889 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4891 * as.h (volatile): Don't define if already defined.
4892 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4894 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4895 declare with format attribute for -Wformat checking.
4897 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4899 * app.c, config/tc-*.c: Don't include read.h, since it is already
4902 * These are based on patches from Minh Tran-le
4903 <mtranle@paris.intellicorp.com>.
4904 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4905 obj_format coffbfd and gas_target i386coff for target.
4906 (i[34]86-*-isc*): New host (uses sysv).
4907 * config/i386aix.mt: Removed (no longer used).
4908 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4910 (LDFLAGS): Added, defined as -shlib.
4911 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4912 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4913 (DOT_LABEL_PREFIX): Define.
4914 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4915 name rather than L0\001.
4916 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4918 * symbols.c, symbols.h (local_bss_counter): Removed.
4919 * write.c (write_object_file): bss no longer uses
4920 local_bss_counter. Pass correct data and bss size to
4921 VMS_write_object_file.

4927 (size_section): Restored sanity check.
4928 (do_relocs_for): Base section address on s_paddr rather than
4929 computing it. Adjust a29k R_IHIHALF special case to account for
4930 section paddr (used to require paddr to be zero). If there are no
4931 reclos, set s_relptr to 0. Set relocation size in object_headers.
4932 (fill_section): Always set s_vaddr here, removing
4933 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4934 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4935 Set STYP_INFO for .comment.
4936 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4937 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4939 H_{SET,GET}_* macros.
4940 (do_linenos_for): Set lineno size in object_headers.
4941 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4942 set s_vaddr here. If string_byte_count remains 4, set it back to
4943 0, and only write strings out if there are some. Call
4944 fill_section before do_relocs_for and do_linenos_for.
4945 (obj_coff_section): Handle optional quoted second argument giving
4946 section characteristics.
4947 (obj_coff_bss): Added to handle .bss.
4948 (obj_coff_ident): Added to handle .ident (puts string in .comment

4951 (fixup_mdeps): Change to segment. Call frag_wane after
4953 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4954 adjustment (already happened only for common symbols, but this is
4956 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

4968 (do_scrub_next_char): For \", return " not '.
4969 (symbol_chars): Now const.
4971 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4972 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4974 * config/obj-coff.h: Don't use #elif.
4976 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4977 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4979 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5003 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5004 using ZERO_BASED_SEGMENTS.
5005 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5006 never set segment address for SEG_E2 (.bss) and don't write out
5007 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5008 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5009 definitions, and don't merge tags with non-tags. Check for .bf
5010 rather than just checking whether the second character is b and
5011 the third character is f.
5012 (obj_coff_val): gcc can generate values which we don't handle
5013 correctly; discard information for now, since it only affects the
5014 debugging information.
5015 (tag_find_or_name): Don't insert tags in the symbol table.
5016 (yank_symbols): Don't merge labels.
5017 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5195 consistently const, and always initialized them. Included read.h.
5197 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5199 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5200 constant will not fit in an immediate field.
5201 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
5203 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

5220 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
5221 so widening works consistently.
5223 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
5225 * version.c: Put conditional "const" before version_string, not

5228 * app.c (do_scrub_next_char): Need double-\ before `000' to show
5229 printed rep of null character.
5231 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
5233 * obj-coffbfd.c (write_object_file): check return value of
5236 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5238 * Support for i386-sysv.
5239 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
5240 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
5241 be used to set them all to zero as was done before.
5242 (fill_section): segment addresses now set in write_object_file.
5243 (fill_section): Don't set STYP_NOLOAD for .bss section.
5244 (fixup_segment): 386 uses strange common symbol format.

5263 * tc-m68k.c (get_num): make it work for all segments, not just the
5266 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

5277 * tc-z8k.c: lots of bug fixes
5279 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5281 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5282 #elif, since it is not supported by old compilers.
5283 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5284 couple of expressions in tc-m68k.c.
5286 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5288 * read.c (cons): If NO_RELOC is defined, use it.
5290 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5292 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5294 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5295 local labels to start with a .) and set REGISTER_PREFIX to %.
5296 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

5314 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5315 sections starting from zero, rather than making them consecutive.
5316 This makes subsequent reloc calculations easier, esp if the object
5317 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5318 allocate lcomm in .data rather than in .bss. It seems that some
5319 tools can't cope with a non-zero sized bss before linkage.
5321 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5323 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5342 * Makefile.in (install): if $(tooldir) exists, install as in
5345 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5347 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5348 .word is < -32768 or > 32767. The -J flag causes the error to be
5349 ignored. This is to catch over-sized switches generated by gcc on
5350 systems which don't support the broken .word hack.
5351 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5352 write.c (fixup_segment): check for signed .word overflow if
5353 WARN_SIGNED_OVERFLOW_WORD.
5355 * write.c (fixup_segment): fixed missing parens in expression
5356 checking for byte or word overflow.

5372 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5374 * input-scrub.c (input_scrub_push): call input_file_begin, not
5376 messages.c (as_perror): print ": " between the passed in error and
5377 the strerror, like perror does.

5382 From Steve Chamberlain:
5383 Makefile.in: Handle m68*-*-coff*.
5384 read.c, read.h: add mult argument to s_space
5386 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5387 Motorola and MIT syntax; gas can now assemble either type of
5389 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5397 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5399 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5402 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5404 * Makefile.in (LIBS): Include opcode library.

5429 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5431 * config/tc-m68k.c (init_table): Now const. Always include 68851
5432 data, so that "bc" is available to 68040 cache instructions.
5433 Added "tt0", "tt1", and 68ec030 variants.
5434 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5435 (enum _register): Added TT0, TT1.
5436 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5437 line number correctly in "internal error" messages. Don't print
5438 architecture-mismatch message for operand errors.
5440 From Colin Smith (colin@wrs.com):
5441 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5442 than install_operand.

5463 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5464 has already been formatted (but may still contain %-characters).
5467 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5469 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5470 written with indirection on the last two operands, which can be
5471 either data or address registers. Added a new operand type 'r'
5472 which accepts either register type. Added '(' to notend stuff in
5473 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5580 ancient or broken compilers.
5582 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5583 processor/opcode mismatch, so reword the error message.

5585 characteristics have been), default to 68020. Don't need extra
5586 quotes around error string.

5684 * configure.in: Recognize sparclite as a sparc variant.
5686 * tc-sparc.c: Use new ARCHITECTURES_CONFLICT_P macro. Mention new
5689 Tue May 26 16:47:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5691 * config/tc-a29k.c: lint

5698 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5700 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
5701 calc the base of relocs correctly.
5702 * tc-a29k.c (parse_operand): allow expressions to be in any section.
5704 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
5706 * as.c, write.c: use -K rather than -k for the broken word warning
5709 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
5711 * Makefile.in: do not print recursion lines.
5713 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)

5717 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5719 * write.c (write_object_file): For b.out format, round up section
5720 start addresses to match required alignment.
5722 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5724 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5725 where gcc looks for it.
5727 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5729 * Makefile.in: Changed some lines to be less confusing for some
5732 * input-file.c: Conditionalize on _IOFBF, not VMS.
5734 * read.c, write.c: Change a series of ifdef/elif to
5735 ifdef/else/ifdef etc.
5737 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)

5743 * Makefile.in: install the man page.
5745 * Makefile.in: pass down MAKEINFO explicitly on info.
5747 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
5749 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5751 * flonum-const.c: renamed flonum-konst.c to stop dos name
5754 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
5756 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
5757 tc-m68k.h to te-sun3.h.
5759 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
5761 * configure.in: vxworks68 gets te-sun3.h.
5763 * expr.c: remove limitation that local_labels_dollar or
5764 local_labels_fb must be < 10.
5766 * symbols.c: remove local_labels_dollar, replace with a function
5767 interface for a sparse array. All users adjusted.
5769 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
5771 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5773 * doc/Makefile.in: commented out line for building as-all.texinfo.
5776 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
5778 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

5790 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
5792 * Makefile.in (strerror.o): Add rule so that broken Sun make can
5795 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5797 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5799 * expr.c (operand): if can't work out what sort of operand it is,
5800 then look through FLT_CHARS for a hint.
5802 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5804 * Makefile.in, configure.in: removed traces of namesubdir,
5805 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5806 copyrights to '92, changed some from Cygnus to FSF.
5808 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5809 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5810 copyrights to '92, changed some from Cygnus to FSF.
5812 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5814 * expr.c: If an expression is single comma, then return with
5815 SEG_ABSENT rather than an error - since the sparc front end does
5816 really strange things with things like fbge,a
5818 * as.h: include bfd.h if using many sections
5819 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5820 local labels didn't work.
5821 * listing.c (list_symbol_table): don't core dump when there's no
5823 * write.c, write.h: call fix_new with the right number of args on
5825 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5828 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5830 * app.c: MRI compatibility - allow single quote to start a string.
5831 * as.c: fix typo recently introduced.
5832 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5833 * expr.c: Much rewriting, to accomodate MRI syntax for
5834 expressions. Also easier to read now.
5835 * listing.c: Put back defuns
5836 * read.c: modified to accept MRI syntax, put back listing pseudo
5837 ops so that an assembler built with NO_LISTING ignores list ops
5839 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5840 machine is a SPARC or a 29K.
5841 * config/obj-aout.c: added s_sect pseudo op
5842 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5843 fill in the timestamp.
5844 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5845 anymore, define all the relocs which the tc-<x> bit will use so we
5846 can translate from them to the coff types.
5847 * config/tc-a29k.c: reloc_type isn't ane enum any more
5848 * config/tc-m68k.c: Added NO_RELOC definition.
5850 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5852 * Makefile.in: put header files before C source for TAGS; remove
5853 references to non-existent syscalls.h.
5855 * read.c, write.c subsegs.c: back out the .bss changes.
5857 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5859 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5863 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5865 * symbols.c (local_label_name): symbols now start with ^A.
5867 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5868 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5869 generate these sections. .align: will use NOP_OPCODE or 0
5870 for padding. This is just for being nice to the
5873 * expr.c (operand): changed to generate local label "\001L0"
5874 starting with a ^A so that it is recognized as a local label.
5876 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5878 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5879 i/o opcodes - inb, inw, outb and outw. string manipulation with
5880 att syntax - scmp, slod, smov, ssca, ssto.
5882 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5883 to just after .file .
5885 In obj_crawl_symbol_chain() where it tries to put the external
5886 symbols apart, with the condition:
5887 (!S_IS_DEFINED(symbolP) &&
5888 !S_IS_DEBUG(symbolP) &&
5889 !SF_GET_STATICS(symbolP))
5890 it was moving too many symbols out. So I switch it back to the
5892 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5894 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5895 so that we don't use the F_RELFLG which make the linker complain
5896 that somebody has stripped the relocation info.
5898 Also, the AIX ld program require that the relocation table
5899 is sorted by r_vaddr like the standard ATT assembler does.
5901 [he also changed the sizeof(struct ...)'s into the coff
5902 style FOOSZ macros. I'm not sure this is right, but I can't
5903 remember why. xoxorich.]
5905 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5907 * Makefile.in, configure.in, doc: use the doc. Build it, install
5910 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5912 * read.c: white space and comments only.
5914 * configure.in: use the new atof-ns32.c for ns32k.
5916 * write.c: comment change only.
5918 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5919 aren't yet integrated.
5921 * tc-i860.[hc]: blew off the dust. Something must still be done
5922 about conflicting relocation types.
5924 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5927 * tc-i960.c, tc-sparc.c: white space and comments only.
5929 * tc-a29k.h: delete duplicate macro definition.
5931 * new file atof-ns32k.c copied from hack's last unreleased gas.
5933 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5935 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5938 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5939 ChangeLog's prior to this are sketchy at best. I have logs.
5940 They just aren't ChangeLogs.
