1270 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1271 the table, require that the one without bit 0x1000000 set come

1383 for keeping or rejecting configurations still under development;
1384 default is to assume production environment, and reject configs
1385 still being worked on. Mark Elf configurations (except sparc and
1386 i386) as developmental. Deleted cases matching some generic names
1387 in favor of more specific names. (E.g., when we get Alpha
1388 support, we'll still only support VMS for Vax.)

1404 through inclusion of tc-hppa.h. Delete all forward declarations
1405 for functions only used within tc-hppa.c, likewise for structures,
1406 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1407 conditional code in a few small places.
1409 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1410 structures, global variables, forward declarations together.

1413 into a few places. Make all functions and variables which
1414 are only used within tc-hppa.c static. PARAMize all functions.
1415 Add comments to functions. Delete unused functions, variables,
1416 #defines, etc. Delete unused members within structures. Delete
1417 ldil;ble hacks -- it is believed they were installed to work
1418 around old gas bugs. Avoid using mixed case for local
1419 functions, variables, and structures. Fix formatting problems
1420 not found by GNU-indent. Add FIXME notices for things which
1421 should be worked on the near future. Delete lots of old
1422 useless (1.36 PA-SOM) code.

2565 * Extensive changes to permit symbols to contain any expression
2566 type and to delay the computation of the expression until the
2567 value is actually needed. This permits setting symbols to values
2568 calculated based on object code size. Expressions were changed to
2569 no longer be in a section, to stop the overloading of segment and
2570 expression type that previously occurred.
2572 * as.c (big_section, pass1_section, diff_section, absent_section):
2574 (expr_section): Added (used for dummy symbols which hold

2658 (previous_section, previous_subsection): New vars.
2659 (obj_elf_section): Save current place in case DWARF code wants us
2660 to pop back to it. Handle unquoted section name as well as quoted
2661 section name. Don't crash on invalid strings.

2771 * Removed sy_forward and replaced it with an undefined expression
2772 as the value of a symbol.
2773 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
2774 sy_resolved and sy_resolving single bit fields.
2775 * symbols.c (symbol_new): Don't initialize sy_forward field.
2776 (resolve_symbol_value): New function to adjust symbol value by
2777 fragment address, using recursion to resolve forward symbols.

2779 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
2780 expression rather than setting symbolP->sy_forward.
2781 * write.c (write_object_file): Use resolve_symbol_value on
2782 symbols, keeping the common case (the old behaviour) inline.

3778 than ECOFF line number information.
3779 (obj_ecoff_stab): Accept non-zero values for stabs line number.

3811 * doc/as.texinfo: First pass at using new texinfo features --
3812 variables, conditional tests. Far from complete.

3840 dependencies are read, not when they are used).
3842 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
3843 a29k .bss section; the mondfe program doesn't like it.

3864 source directory, if that's not the current directory.
3866 * configure.in (per-host): Accept MIPS host with BSD version

3888 process relocs if there aren't any relocs to process. Avoids
3889 malloc/free bug on SCO too.
3891 * as.h: Move local include files below system include files, to
3892 avoid some redefinition complaints on some systems.
3893 (const, volatile): Don't need these conditionally defined if we
3894 use CONST and VOLATILE from ansidecl.h.
3895 (seg_name): Use CONST, not const.
3897 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3899 * config/tc-mips.c: Reindented to GNU standards.

3903 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3904 (fixup_segment): Add a29k special case; the linker is not prepared
3905 to see a segment offset here.
3907 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3910 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3912 * Makefile.in: add dvi target; as-$(config).texinfo might live in

3928 bignums, but don't emit error message.
3930 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3932 * Makefile.in (targ-cpu.o): Depend on config.h.
3934 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3936 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3937 dropping a space immediately following an identifier.
3938 * expr.c, write.c: Rewrote assert expressions to not use multiple
3939 lines; I don't think that can be done portably.
3940 * config/tc-mips.c (macro): Use $AT if target register is zero in
3941 load instruction, which it can be for a floating point load.
3943 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3964 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3966 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3967 to be on a single line.

4015 prototypes for all static functions. Moved existing minimal
4016 debugging format support info #ifndef OBJ_ECOFF blocks.

4018 does not support a non sign extended high 16 bits reloc. Adjusted
4019 all callers accordingly.
4020 (tc_get_register): Renamed from get_register, and made non-static.
4022 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4065 * make-gas.com: Find obstack.obj if it's not in the current
4067 * read.c (s_ignore): Don't declare is_end_of_line. It's
4068 redundant, and triggers a VMS gcc compiler bug.
4070 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4071 current segment as an argument. (Ignored in all cases but VMS.)
4072 All callers and definitions changed.

4203 for now; should be machine-dependent.
4205 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
4206 targets, forcing BFD use.

4369 md_relax_table): Use default zero initialization.
4370 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4371 latter, instead of selecting with preprocessor conditionals.
4373 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4375 * configure.in: recognise all sparclite variants

4383 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4385 * expr.c (operand): If character other than comma or newline is a
4386 logical end-of-line character, use the newline case.
4387 From Eric Youngdale:
4388 (operand): Set X_add_number field for floating-point numbers.
4389 (operand): Treat zero byte as end-of-operand.
4391 * configure.in (per-target): Look for with_bfd_assembler option.
4392 For now, only accept "no", until the merge is done.
4394 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4395 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4396 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4397 * read.c: Finish conversion to S_* macros in the VMS only
4398 parts of the program. Add "const" modifier to hex_value.
4399 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4401 * expr.c: Add "const" modifier to hex_value.
4402 * symbols.c: Finish conversion to S_* macros in the VMS only
4403 parts of the program. Add "const" modifier to
4404 md_[long,short]_jump_size. Remove declaration of const_flag
4405 (which will be declared in obj-vms.h).
4406 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4407 Fix arguments to VMS_write_object_file.
4408 * config-gas.com: New file. Script for VMS systems to set up the
4409 configuration to build gas for VMS, and create config.status.
4410 * make-gas.com: Redone to work with new scheme.
4411 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4413 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4414 will swap bytes if needed on a big endian system. Use throughout
4416 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4417 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4418 types of malformed stabs. Change parsing algorithm so that we are
4419 more certain of having all of the information that we need on hand.
4420 * obj-vms.c (final_forward_reference): New function, used to help
4421 resolve the data types of as many struct elements as possible
4422 when some part of the struct is not fully defined by the compiler.

4425 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4426 as symbols as well in the object file. Look for external functions
4427 that start with "__vt.", and turn them into variables, since the
4428 g++ compiler is incapable of doing this.
4429 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4431 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4432 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4433 have the name of the source file yet.
4434 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4436 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4438 * read.c (s_data): Always use "data_section", since it'll map to
4439 SEG_DATA or SEG_E1 if needed.
4440 (s_lcomm): Likewise with bss_section.
4441 (s_fill): Use memset, not bzero.
4443 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4464 (section_alignment): Declare only if not BFD_ASSEMBLER.
4465 (big_section, reg_section, pass1_section, diff_section,
4466 absent_section, text_section, data_section, bss_section): If
4467 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4468 mapping to segT enum values.
4469 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4470 if these are used or defined, if BFD_ASSEMBLER.
4471 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4472 subseg_new split into two functions.
4473 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4475 * as.h (volatile): Don't define if already defined.
4476 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4478 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4479 declare with format attribute for -Wformat checking.
4481 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4483 * app.c, config/tc-*.c: Don't include read.h, since it is already
4486 * These are based on patches from Minh Tran-le
4487 <mtranle@paris.intellicorp.com>.
4488 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4489 obj_format coffbfd and gas_target i386coff for target.
4490 (i[34]86-*-isc*): New host (uses sysv).
4491 * config/i386aix.mt: Removed (no longer used).
4492 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4494 (LDFLAGS): Added, defined as -shlib.
4495 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4496 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4497 (DOT_LABEL_PREFIX): Define.
4498 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4499 name rather than L0\001.
4500 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4502 * symbols.c, symbols.h (local_bss_counter): Removed.
4503 * write.c (write_object_file): bss no longer uses
4504 local_bss_counter. Pass correct data and bss size to
4505 VMS_write_object_file.

4511 (size_section): Restored sanity check.
4512 (do_relocs_for): Base section address on s_paddr rather than
4513 computing it. Adjust a29k R_IHIHALF special case to account for
4514 section paddr (used to require paddr to be zero). If there are no
4515 reclos, set s_relptr to 0. Set relocation size in object_headers.
4516 (fill_section): Always set s_vaddr here, removing
4517 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4518 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4519 Set STYP_INFO for .comment.
4520 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4521 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4523 H_{SET,GET}_* macros.
4524 (do_linenos_for): Set lineno size in object_headers.
4525 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4526 set s_vaddr here. If string_byte_count remains 4, set it back to
4527 0, and only write strings out if there are some. Call
4528 fill_section before do_relocs_for and do_linenos_for.
4529 (obj_coff_section): Handle optional quoted second argument giving
4530 section characteristics.
4531 (obj_coff_bss): Added to handle .bss.
4532 (obj_coff_ident): Added to handle .ident (puts string in .comment

4552 (do_scrub_next_char): For \", return " not '.
4553 (symbol_chars): Now const.
4555 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4556 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4558 * config/obj-coff.h: Don't use #elif.
4560 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4561 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4563 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4565 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4585 SEG_BSS, fill with NOP_OPCODE.
4586 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4587 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4588 using ZERO_BASED_SEGMENTS.
4589 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4590 never set segment address for SEG_E2 (.bss) and don't write out
4591 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4592 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4593 definitions, and don't merge tags with non-tags. Check for .bf
4594 rather than just checking whether the second character is b and
4595 the third character is f.
4596 (obj_coff_val): gcc can generate values which we don't handle
4597 correctly; discard information for now, since it only affects the
4598 debugging information.
4599 (tag_find_or_name): Don't insert tags in the symbol table.
4600 (yank_symbols): Don't merge labels.
4601 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4656 options. Updated options documentation for m68k. Some minor
4657 wording/punctuation changes.

4744 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
4746 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
4747 could be doing emulation.
4749 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4752 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4779 consistently const, and always initialized them. Included read.h.
4781 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4783 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4784 constant will not fit in an immediate field.
4785 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
4787 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
4789 * obj-coff.c (callj_table): Delete global variable.

4804 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
4805 so widening works consistently.
4807 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
4809 * version.c: Put conditional "const" before version_string, not

4820 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4822 * Support for i386-sysv.
4823 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
4824 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
4825 be used to set them all to zero as was done before.

4827 (fill_section): Don't set STYP_NOLOAD for .bss section.
4828 (fixup_segment): 386 uses strange common symbol format.

4861 * tc-z8k.c: lots of bug fixes
4863 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4865 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4866 #elif, since it is not supported by old compilers.
4867 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4868 couple of expressions in tc-m68k.c.
4870 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4872 * read.c (cons): If NO_RELOC is defined, use it.
4874 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4876 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4878 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4879 local labels to start with a .) and set REGISTER_PREFIX to %.
4880 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4882 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4896 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4898 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4899 sections starting from zero, rather than making them consecutive.
4900 This makes subsequent reloc calculations easier, esp if the object
4901 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4902 allocate lcomm in .data rather than in .bss. It seems that some
4903 tools can't cope with a non-zero sized bss before linkage.
4905 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4907 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
4908 throughout. That enum no longer means what we thought it meant.

4922 Change LIBDEPS dependence to LIBS.
4924 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4926 * Makefile.in (install): if $(tooldir) exists, install as in
4929 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4931 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4932 .word is < -32768 or > 32767. The -J flag causes the error to be
4933 ignored. This is to catch over-sized switches generated by gcc on
4934 systems which don't support the broken .word hack.
4935 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4936 write.c (fixup_segment): check for signed .word overflow if
4937 WARN_SIGNED_OVERFLOW_WORD.
4939 * write.c (fixup_segment): fixed missing parens in expression
4940 checking for byte or word overflow.
4942 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

4954 * tc-i386.h : new coff defines
4956 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4958 * input-scrub.c (input_scrub_push): call input_file_begin, not
4960 messages.c (as_perror): print ": " between the passed in error and
4961 the strerror, like perror does.
4963 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
4965 * Makefile.in: use gas_target instead of modifying target_cpu.
4966 From Steve Chamberlain:
4967 Makefile.in: Handle m68*-*-coff*.
4968 read.c, read.h: add mult argument to s_space
4970 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4971 Motorola and MIT syntax; gas can now assemble either type of
4973 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4979 (write_object_file) call fixup_mdeps
4980 (fixup_segment) set fx_subsy to 0.
4981 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4983 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4986 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4988 * Makefile.in (LIBS): Include opcode library.
4990 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5010 tc-i960.c (md_ri_to_chars): Always output bout object file in
5011 little endian byte order (used to use endianness of host).
5013 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5015 * config/tc-m68k.c (init_table): Now const. Always include 68851
5016 data, so that "bc" is available to 68040 cache instructions.
5017 Added "tt0", "tt1", and 68ec030 variants.
5018 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5019 (enum _register): Added TT0, TT1.
5020 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5021 line number correctly in "internal error" messages. Don't print
5022 architecture-mismatch message for operand errors.
5024 From Colin Smith (colin@wrs.com):
5025 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5026 than install_operand.

5030 * listing.c (buffer_line): rewind to the start of include
5031 files, they might be included twice.

5040 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5042 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5043 so that we can assemble hand-written libgcc code.
5045 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5047 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5048 has already been formatted (but may still contain %-characters).
5051 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5053 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5054 written with indirection on the last two operands, which can be
5055 either data or address registers. Added a new operand type 'r'
5056 which accepts either register type. Added '(' to notend stuff in
5057 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5059 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

5073 (relax_align): If linkrelax, provide extra padding.
5075 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5076 their not having symbols associated.
5078 * tc-i960.c (norelax, instrument_branches): Default initializer is
5080 (linkrelax): Delete variable definition.

5103 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
5104 being used with args swapped, causing occasional lossage when
5105 refilling buffers after an include file.
5107 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5109 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
5110 version. Discard bogus DONTDEF version.
5111 (as_warn, as_bad, as_fatal): Likewise.

5115 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5116 selected architecture, print a message saying so and listing what

5138 * read.c (s_fill): make the .fill size clamped error a warn and
5139 fix bug where 0's were always placed.
5141 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
5142 two bytes of any constant with 0xff:

5161 * configure.in (mips host): Accept "ultrix" with version number.
5163 * expr.c (floating_constant): Separate "=-" to avoid confusing
5164 ancient or broken compilers.
5166 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5167 processor/opcode mismatch, so reword the error message.
5168 (md_assemble): If no CPU has been set (even if FPU/PMMU
5169 characteristics have been), default to 68020. Don't need extra
5170 quotes around error string.
5172 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5174 * read.c (potable): Revert sac's incorrect change made Jul 13.

5252 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5254 * write.c (write_object_file): keep the fix_tail clean, which
5255 fixes a bug in -R where relocations were being lost.
5257 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5259 * configure.in: recognize m680x0 as having sun3 emulation mode for

5286 * tc-a29k.c (parse_operand): allow expressions to be in any section.
5288 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)

5304 start addresses to match required alignment.
5306 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5308 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5309 where gcc looks for it.
5311 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5313 * Makefile.in: Changed some lines to be less confusing for some

5379 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5381 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5383 * expr.c (operand): if can't work out what sort of operand it is,
5384 then look through FLT_CHARS for a hint.
5386 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5388 * Makefile.in, configure.in: removed traces of namesubdir,

5390 copyrights to '92, changed some from Cygnus to FSF.
5392 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5393 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5394 copyrights to '92, changed some from Cygnus to FSF.
5396 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5398 * expr.c: If an expression is single comma, then return with
5399 SEG_ABSENT rather than an error - since the sparc front end does
5400 really strange things with things like fbge,a
5402 * as.h: include bfd.h if using many sections
5403 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5404 local labels didn't work.
5405 * listing.c (list_symbol_table): don't core dump when there's no
5407 * write.c, write.h: call fix_new with the right number of args on
5409 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5412 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5414 * app.c: MRI compatibility - allow single quote to start a string.
5415 * as.c: fix typo recently introduced.
5416 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5417 * expr.c: Much rewriting, to accomodate MRI syntax for
5418 expressions. Also easier to read now.
5419 * listing.c: Put back defuns
5420 * read.c: modified to accept MRI syntax, put back listing pseudo
5421 ops so that an assembler built with NO_LISTING ignores list ops
5423 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5424 machine is a SPARC or a 29K.
5425 * config/obj-aout.c: added s_sect pseudo op
5426 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5427 fill in the timestamp.
5428 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5429 anymore, define all the relocs which the tc-<x> bit will use so we
5430 can translate from them to the coff types.
5431 * config/tc-a29k.c: reloc_type isn't ane enum any more
5432 * config/tc-m68k.c: Added NO_RELOC definition.
5434 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5436 * Makefile.in: put header files before C source for TAGS; remove
5437 references to non-existent syscalls.h.
5439 * read.c, write.c subsegs.c: back out the .bss changes.
5441 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5443 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5447 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5449 * symbols.c (local_label_name): symbols now start with ^A.
5451 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5452 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5453 generate these sections. .align: will use NOP_OPCODE or 0
5454 for padding. This is just for being nice to the
5457 * expr.c (operand): changed to generate local label "\001L0"
5458 starting with a ^A so that it is recognized as a local label.
5460 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5462 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5463 i/o opcodes - inb, inw, outb and outw. string manipulation with
5464 att syntax - scmp, slod, smov, ssca, ssto.
5466 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5467 to just after .file .
5469 In obj_crawl_symbol_chain() where it tries to put the external
5470 symbols apart, with the condition:
5471 (!S_IS_DEFINED(symbolP) &&
5472 !S_IS_DEBUG(symbolP) &&
5473 !SF_GET_STATICS(symbolP))
5474 it was moving too many symbols out. So I switch it back to the
5476 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5478 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5479 so that we don't use the F_RELFLG which make the linker complain
5480 that somebody has stripped the relocation info.
5482 Also, the AIX ld program require that the relocation table
5483 is sorted by r_vaddr like the standard ATT assembler does.
5485 [he also changed the sizeof(struct ...)'s into the coff
5486 style FOOSZ macros. I'm not sure this is right, but I can't
5487 remember why. xoxorich.]
5489 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5491 * Makefile.in, configure.in, doc: use the doc. Build it, install
5494 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5496 * read.c: white space and comments only.
5498 * configure.in: use the new atof-ns32.c for ns32k.
5500 * write.c: comment change only.
5502 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5503 aren't yet integrated.
5505 * tc-i860.[hc]: blew off the dust. Something must still be done
5506 about conflicting relocation types.
5508 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5511 * tc-i960.c, tc-sparc.c: white space and comments only.
5513 * tc-a29k.h: delete duplicate macro definition.
5515 * new file atof-ns32k.c copied from hack's last unreleased gas.
5517 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5519 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5522 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5523 ChangeLog's prior to this are sketchy at best. I have logs.
5524 They just aren't ChangeLogs.
