1519 * configure.in: Set bfd_gas for all sparc targets. Added facility
1520 for keeping or rejecting configurations still under development;
1521 default is to assume production environment, and reject configs
1522 still being worked on. Mark Elf configurations (except sparc and
1523 i386) as developmental. Deleted cases matching some generic names
1524 in favor of more specific names. (E.g., when we get Alpha

1542 for functions only used within tc-hppa.c, likewise for structures,
1543 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1544 conditional code in a few small places.
1546 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1547 structures, global variables, forward declarations together.

1550 into a few places. Make all functions and variables which
1551 are only used within tc-hppa.c static. PARAMize all functions.
1552 Add comments to functions. Delete unused functions, variables,
1553 #defines, etc. Delete unused members within structures. Delete
1554 ldil;ble hacks -- it is believed they were installed to work
1555 around old gas bugs. Avoid using mixed case for local
1556 functions, variables, and structures. Fix formatting problems
1557 not found by GNU-indent. Add FIXME notices for things which
1558 should be worked on the near future. Delete lots of old
1559 useless (1.36 PA-SOM) code.

1576 * config/tc-hppa.c: Likewise.
1578 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1579 of elf32_symbol_type.
1580 (pa_export_args): Likewise.
1581 (elf_hppa_final_processing): Likewise.

1588 a multiple of the section alignment rather than always a
1591 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

1632 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1634 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1635 ELF, since the ELF object format does not have these type of
1636 relocations. Change the abort into as as_bad and return
1637 BFD_RELOC_NONE to silence compiler warnings.
1638 (md_assemble): Keep track of the instruction size. Allow white
1639 space between the $ and the constant for compatibility with older
1640 gases and other assemblers.

4029 avoid some redefinition complaints on some systems.
4030 (const, volatile): Don't need these conditionally defined if we
4031 use CONST and VOLATILE from ansidecl.h.
4032 (seg_name): Use CONST, not const.

4040 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4041 (fixup_segment): Add a29k special case; the linker is not prepared
4042 to see a segment offset here.

4047 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4049 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4050 srcdir, might be in objdir.

4069 * Makefile.in (targ-cpu.o): Depend on config.h.
4071 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4073 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4074 dropping a space immediately following an identifier.

4076 lines; I don't think that can be done portably.
4077 * config/tc-mips.c (macro): Use $AT if target register is zero in
4078 load instruction, which it can be for a floating point load.
4080 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4101 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4103 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4104 to be on a single line.

4152 prototypes for all static functions. Moved existing minimal
4153 debugging format support info #ifndef OBJ_ECOFF blocks.

4202 * make-gas.com: Find obstack.obj if it's not in the current
4204 * read.c (s_ignore): Don't declare is_end_of_line. It's
4205 redundant, and triggers a VMS gcc compiler bug.
4207 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4208 current segment as an argument. (Ignored in all cases but VMS.)
4209 All callers and definitions changed.

4228 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
4229 Call elf_xstabs for .stabs and .xstabs operators.
4231 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
4233 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
4236 * configure.in: mips-bsd configuration was missing format spec.
4239 * Makefile.in (Makefile): Depends on configure.in.

4506 md_relax_table): Use default zero initialization.
4507 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4508 latter, instead of selecting with preprocessor conditionals.
4510 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4512 * configure.in: recognise all sparclite variants

4522 * expr.c (operand): If character other than comma or newline is a
4523 logical end-of-line character, use the newline case.
4524 From Eric Youngdale:
4525 (operand): Set X_add_number field for floating-point numbers.
4526 (operand): Treat zero byte as end-of-operand.
4528 * configure.in (per-target): Look for with_bfd_assembler option.
4529 For now, only accept "no", until the merge is done.
4531 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4532 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4538 * expr.c: Add "const" modifier to hex_value.
4539 * symbols.c: Finish conversion to S_* macros in the VMS only
4540 parts of the program. Add "const" modifier to
4541 md_[long,short]_jump_size. Remove declaration of const_flag
4542 (which will be declared in obj-vms.h).
4543 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4544 Fix arguments to VMS_write_object_file.
4545 * config-gas.com: New file. Script for VMS systems to set up the
4546 configuration to build gas for VMS, and create config.status.
4547 * make-gas.com: Redone to work with new scheme.
4548 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4550 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

4553 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4554 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4555 types of malformed stabs. Change parsing algorithm so that we are
4556 more certain of having all of the information that we need on hand.
4557 * obj-vms.c (final_forward_reference): New function, used to help
4558 resolve the data types of as many struct elements as possible
4559 when some part of the struct is not fully defined by the compiler.

4562 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4563 as symbols as well in the object file. Look for external functions

4566 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4568 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

4576 SEG_DATA or SEG_E1 if needed.
4577 (s_lcomm): Likewise with bss_section.
4578 (s_fill): Use memset, not bzero.
4580 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4605 mapping to segT enum values.
4606 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4607 if these are used or defined, if BFD_ASSEMBLER.
4608 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4609 subseg_new split into two functions.
4610 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4612 * as.h (volatile): Don't define if already defined.
4613 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4615 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4616 declare with format attribute for -Wformat checking.
4618 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4620 * app.c, config/tc-*.c: Don't include read.h, since it is already

4633 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4634 (DOT_LABEL_PREFIX): Define.

4636 name rather than L0\001.
4637 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4639 * symbols.c, symbols.h (local_bss_counter): Removed.
4640 * write.c (write_object_file): bss no longer uses

4648 (size_section): Restored sanity check.
4649 (do_relocs_for): Base section address on s_paddr rather than
4650 computing it. Adjust a29k R_IHIHALF special case to account for

4652 reclos, set s_relptr to 0. Set relocation size in object_headers.
4653 (fill_section): Always set s_vaddr here, removing
4654 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4655 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4656 Set STYP_INFO for .comment.
4657 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4658 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4660 H_{SET,GET}_* macros.
4661 (do_linenos_for): Set lineno size in object_headers.
4662 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4663 set s_vaddr here. If string_byte_count remains 4, set it back to
4664 0, and only write strings out if there are some. Call
4665 fill_section before do_relocs_for and do_linenos_for.
4666 (obj_coff_section): Handle optional quoted second argument giving
4667 section characteristics.
4668 (obj_coff_bss): Added to handle .bss.
4669 (obj_coff_ident): Added to handle .ident (puts string in .comment

4693 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4695 * config/obj-coff.h: Don't use #elif.
4697 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4698 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4700 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

4712 Sun Dec 13 00:04:38 1992 Ian Lance Taylor (ian@cygnus.com)
4714 * read.c (read_a_source_file): avoid calling xmalloc (0).
4716 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
4718 * listing.c: Call xmalloc, not malloc; don't declare malloc.
4720 * Changes to support SCO 3.2v4:
4721 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
4722 SEG_BSS, fill with NOP_OPCODE.
4723 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4724 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4725 using ZERO_BASED_SEGMENTS.
4726 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4727 never set segment address for SEG_E2 (.bss) and don't write out
4728 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4729 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4730 definitions, and don't merge tags with non-tags. Check for .bf
4731 rather than just checking whether the second character is b and
4732 the third character is f.
4733 (obj_coff_val): gcc can generate values which we don't handle
4734 correctly; discard information for now, since it only affects the
4735 debugging information.

4737 (yank_symbols): Don't merge labels.
4738 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4740 set segment address if ZERO_BASED_SEGMENTS.
4741 (obj_coff_section): Accept and ignore a trailing quoted string, as
4742 used in AT&T i386 syntax.

4744 relative addends by the segment vaddr.
4745 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
4746 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
4747 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

4848 xrealloc from xrealloc.c.
4849 * xrealloc.c: Deleted.
4850 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
4852 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
4855 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
4857 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

4876 * all files: Whitespace changes for GNU indentation style, done by
4877 GNU `indent'. Some cleanup still needed, especially of comments.
4879 * configure.in: No te-386bsd.h file exists; don't try to use it.
4881 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
4883 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
4884 could be doing emulation.
4886 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4889 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
4892 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
4894 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

4918 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4920 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4921 constant will not fit in an immediate field.
4922 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
4924 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
4926 * obj-coff.c (callj_table): Delete global variable.

4944 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
4946 * version.c: Put conditional "const" before version_string, not

4957 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4959 * Support for i386-sysv.
4960 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4964 (fill_section): Don't set STYP_NOLOAD for .bss section.
4965 (fixup_segment): 386 uses strange common symbol format.

4979 fix i960+non-bfd coff bit rot.
4980 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
4981 support for C source listings. (obj_coff_endef): look in the right

4998 * tc-z8k.c: lots of bug fixes
5000 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5002 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5003 #elif, since it is not supported by old compilers.
5004 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5005 couple of expressions in tc-m68k.c.
5007 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5009 * read.c (cons): If NO_RELOC is defined, use it.
5011 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5013 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5015 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5016 local labels to start with a .) and set REGISTER_PREFIX to %.
5017 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5019 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
5021 * messages.c: Comment changes.
5023 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

5026 * messages.c: If __STDC__ is not defined, define NO_STDARG.
5028 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
5030 * listing.c (debugging_pseudo): Add stabs and stabn as things to
5033 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5035 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5036 sections starting from zero, rather than making them consecutive.
5037 This makes subsequent reloc calculations easier, esp if the object
5038 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5039 allocate lcomm in .data rather than in .bss. It seems that some
5040 tools can't cope with a non-zero sized bss before linkage.
5042 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5044 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5045 throughout. That enum no longer means what we thought it meant.

5048 "-mno-688[58]1" options.
5050 * tc-m68k.c: Added CPU32 support.

5058 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
5059 Change LIBDEPS dependence to LIBS.
5061 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
5063 * Makefile.in (install): if $(tooldir) exists, install as in
5066 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5068 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5069 .word is < -32768 or > 32767. The -J flag causes the error to be
5070 ignored. This is to catch over-sized switches generated by gcc on
5071 systems which don't support the broken .word hack.
5072 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5073 write.c (fixup_segment): check for signed .word overflow if
5074 WARN_SIGNED_OVERFLOW_WORD.
5076 * write.c (fixup_segment): fixed missing parens in expression
5077 checking for byte or word overflow.
5079 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
5080 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
5081 WARN_SIGNED_OVERFLOW_WORD.

5089 * obj-coffbfd.h : added stuff
5090 * tc-i386.c (tc_coff_fix2rtype): new function
5091 * tc-i386.h : new coff defines
5093 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5095 * input-scrub.c (input_scrub_push): call input_file_begin, not
5097 messages.c (as_perror): print ": " between the passed in error and
5098 the strerror, like perror does.
5100 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
5102 * Makefile.in: use gas_target instead of modifying target_cpu.
5103 From Steve Chamberlain:
5104 Makefile.in: Handle m68*-*-coff*.
5105 read.c, read.h: add mult argument to s_space
5107 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5108 Motorola and MIT syntax; gas can now assemble either type of
5110 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
5111 From Steve Chamberlain:
5112 m68kcoff.mt: for m68k COFF.
5113 obj-coffbfd.c: (fixup_mdeps) added
5114 (size_section) removed bad sanity check
5115 (fill_section) added rs_machine_dependent case
5116 (write_object_file) call fixup_mdeps
5117 (fixup_segment) set fx_subsy to 0.
5118 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5120 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5123 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5125 * Makefile.in (LIBS): Include opcode library.
5127 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
5129 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers

5147 tc-i960.c (md_ri_to_chars): Always output bout object file in
5148 little endian byte order (used to use endianness of host).
5150 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5152 * config/tc-m68k.c (init_table): Now const. Always include 68851
5153 data, so that "bc" is available to 68040 cache instructions.
5154 Added "tt0", "tt1", and 68ec030 variants.
5155 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5156 (enum _register): Added TT0, TT1.
5157 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5158 line number correctly in "internal error" messages. Don't print
5159 architecture-mismatch message for operand errors.
5161 From Colin Smith (colin@wrs.com):
5162 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5163 than install_operand.
5165 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5167 * listing.c (buffer_line): rewind to the start of include
5168 files, they might be included twice.
5170 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
5172 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
5174 * Makefile.in: defined TARGET_CPU for C code so that it can choose
5175 one element of a family.
5177 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5179 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5180 so that we can assemble hand-written libgcc code.
5182 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5184 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5185 has already been formatted (but may still contain %-characters).
5188 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5190 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5191 written with indirection on the last two operands, which can be
5192 either data or address registers. Added a new operand type 'r'
5193 which accepts either register type. Added '(' to notend stuff in

5443 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5445 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5446 where gcc looks for it.
5448 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5450 * Makefile.in: Changed some lines to be less confusing for some

5520 * expr.c (operand): if can't work out what sort of operand it is,
5521 then look through FLT_CHARS for a hint.
5523 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5525 * Makefile.in, configure.in: removed traces of namesubdir,

5529 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5530 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5531 copyrights to '92, changed some from Cygnus to FSF.
5533 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5535 * expr.c: If an expression is single comma, then return with
5536 SEG_ABSENT rather than an error - since the sparc front end does
5537 really strange things with things like fbge,a
5539 * as.h: include bfd.h if using many sections
5540 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5541 local labels didn't work.
5542 * listing.c (list_symbol_table): don't core dump when there's no
5544 * write.c, write.h: call fix_new with the right number of args on

5549 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5551 * app.c: MRI compatibility - allow single quote to start a string.
5552 * as.c: fix typo recently introduced.
5553 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5554 * expr.c: Much rewriting, to accomodate MRI syntax for
5555 expressions. Also easier to read now.
5556 * listing.c: Put back defuns
5557 * read.c: modified to accept MRI syntax, put back listing pseudo
5558 ops so that an assembler built with NO_LISTING ignores list ops
5560 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5561 machine is a SPARC or a 29K.
5562 * config/obj-aout.c: added s_sect pseudo op
5563 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5564 fill in the timestamp.
5565 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5566 anymore, define all the relocs which the tc-<x> bit will use so we
5567 can translate from them to the coff types.
5568 * config/tc-a29k.c: reloc_type isn't ane enum any more
5569 * config/tc-m68k.c: Added NO_RELOC definition.
5571 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5573 * Makefile.in: put header files before C source for TAGS; remove
5574 references to non-existent syscalls.h.
5576 * read.c, write.c subsegs.c: back out the .bss changes.
5578 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5580 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5584 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5586 * symbols.c (local_label_name): symbols now start with ^A.
5588 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5589 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5590 generate these sections. .align: will use NOP_OPCODE or 0
5591 for padding. This is just for being nice to the
5594 * expr.c (operand): changed to generate local label "\001L0"
5595 starting with a ^A so that it is recognized as a local label.
5597 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5599 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5600 i/o opcodes - inb, inw, outb and outw. string manipulation with
5601 att syntax - scmp, slod, smov, ssca, ssto.
5603 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5604 to just after .file .
5606 In obj_crawl_symbol_chain() where it tries to put the external
5607 symbols apart, with the condition:
5608 (!S_IS_DEFINED(symbolP) &&
5609 !S_IS_DEBUG(symbolP) &&
5610 !SF_GET_STATICS(symbolP))
5611 it was moving too many symbols out. So I switch it back to the
5613 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5615 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5616 so that we don't use the F_RELFLG which make the linker complain
5617 that somebody has stripped the relocation info.
5619 Also, the AIX ld program require that the relocation table
5620 is sorted by r_vaddr like the standard ATT assembler does.
5622 [he also changed the sizeof(struct ...)'s into the coff
5623 style FOOSZ macros. I'm not sure this is right, but I can't
5624 remember why. xoxorich.]
5626 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

5633 * read.c: white space and comments only.
5635 * configure.in: use the new atof-ns32.c for ns32k.
5637 * write.c: comment change only.
5639 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5640 aren't yet integrated.
5642 * tc-i860.[hc]: blew off the dust. Something must still be done
5643 about conflicting relocation types.
5645 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5648 * tc-i960.c, tc-sparc.c: white space and comments only.
5650 * tc-a29k.h: delete duplicate macro definition.
5652 * new file atof-ns32k.c copied from hack's last unreleased gas.
5654 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5656 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5659 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5660 ChangeLog's prior to this are sketchy at best. I have logs.
5661 They just aren't ChangeLogs.
