2030 for keeping or rejecting configurations still under development;
2031 default is to assume production environment, and reject configs
2032 still being worked on. Mark Elf configurations (except sparc and
2033 i386) as developmental. Deleted cases matching some generic names
2034 in favor of more specific names. (E.g., when we get Alpha

2053 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2054 conditional code in a few small places.
2056 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2057 structures, global variables, forward declarations together.

2060 into a few places. Make all functions and variables which
2061 are only used within tc-hppa.c static. PARAMize all functions.
2062 Add comments to functions. Delete unused functions, variables,
2063 #defines, etc. Delete unused members within structures. Delete
2064 ldil;ble hacks -- it is believed they were installed to work
2065 around old gas bugs. Avoid using mixed case for local
2066 functions, variables, and structures. Fix formatting problems
2067 not found by GNU-indent. Add FIXME notices for things which
2068 should be worked on the near future. Delete lots of old
2069 useless (1.36 PA-SOM) code.

2086 * config/tc-hppa.c: Likewise.
2088 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2089 of elf32_symbol_type.
2090 (pa_export_args): Likewise.
2091 (elf_hppa_final_processing): Likewise.

2142 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2144 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2145 ELF, since the ELF object format does not have these type of
2146 relocations. Change the abort into as as_bad and return
2147 BFD_RELOC_NONE to silence compiler warnings.
2148 (md_assemble): Keep track of the instruction size. Allow white
2149 space between the $ and the constant for compatibility with older
2150 gases and other assemblers.

4539 avoid some redefinition complaints on some systems.
4540 (const, volatile): Don't need these conditionally defined if we
4541 use CONST and VOLATILE from ansidecl.h.
4542 (seg_name): Use CONST, not const.

4550 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

4557 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4559 * Makefile.in: add dvi target; as-$(config).texinfo might live in

4584 dropping a space immediately following an identifier.

4586 lines; I don't think that can be done portably.
4587 * config/tc-mips.c (macro): Use $AT if target register is zero in
4588 load instruction, which it can be for a floating point load.

4611 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4613 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4614 to be on a single line.

4662 prototypes for all static functions. Moved existing minimal
4663 debugging format support info #ifndef OBJ_ECOFF blocks.

4714 * read.c (s_ignore): Don't declare is_end_of_line. It's
4715 redundant, and triggers a VMS gcc compiler bug.
4717 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4718 current segment as an argument. (Ignored in all cases but VMS.)
4719 All callers and definitions changed.

4728 * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
4729 so "~0x80" won't be rejected.

4732 (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
4733 (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
4735 (obj_elf_xstab): New routine.
4736 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
4737 argument to s_ignore. Put "#if 0" around unused code.
4738 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
4739 Call elf_xstabs for .stabs and .xstabs operators.
4741 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
4743 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
4746 * configure.in: mips-bsd configuration was missing format spec.
4749 * Makefile.in (Makefile): Depends on configure.in.
4751 * config/tc-mips.c (append_insn): Don't check for alignment of
4752 frag in memory; alignment of instructions in section is a separate
4755 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

4850 for now; should be machine-dependent.
4852 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
4853 targets, forcing BFD use.

5016 md_relax_table): Use default zero initialization.
5017 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

5030 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5032 * expr.c (operand): If character other than comma or newline is a
5033 logical end-of-line character, use the newline case.
5034 From Eric Youngdale:
5035 (operand): Set X_add_number field for floating-point numbers.
5036 (operand): Treat zero byte as end-of-operand.
5038 * configure.in (per-target): Look for with_bfd_assembler option.
5039 For now, only accept "no", until the merge is done.
5041 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5042 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5043 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5044 * read.c: Finish conversion to S_* macros in the VMS only
5045 parts of the program. Add "const" modifier to hex_value.
5046 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5048 * expr.c: Add "const" modifier to hex_value.
5049 * symbols.c: Finish conversion to S_* macros in the VMS only
5050 parts of the program. Add "const" modifier to
5051 md_[long,short]_jump_size. Remove declaration of const_flag
5052 (which will be declared in obj-vms.h).
5053 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5054 Fix arguments to VMS_write_object_file.
5055 * config-gas.com: New file. Script for VMS systems to set up the
5056 configuration to build gas for VMS, and create config.status.
5057 * make-gas.com: Redone to work with new scheme.
5058 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5060 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5061 will swap bytes if needed on a big endian system. Use throughout
5063 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5064 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5065 types of malformed stabs. Change parsing algorithm so that we are
5066 more certain of having all of the information that we need on hand.
5067 * obj-vms.c (final_forward_reference): New function, used to help
5068 resolve the data types of as many struct elements as possible
5069 when some part of the struct is not fully defined by the compiler.
5070 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5072 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5073 as symbols as well in the object file. Look for external functions
5074 that start with "__vt.", and turn them into variables, since the
5075 g++ compiler is incapable of doing this.
5076 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5078 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5079 * input-scrub.c (as_where): Fix bug where as would crash if we did not

5083 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5085 * read.c (s_data): Always use "data_section", since it'll map to
5086 SEG_DATA or SEG_E1 if needed.
5087 (s_lcomm): Likewise with bss_section.
5088 (s_fill): Use memset, not bzero.
5090 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
5092 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

5112 (big_section, reg_section, pass1_section, diff_section,
5113 absent_section, text_section, data_section, bss_section): If
5114 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5115 mapping to segT enum values.
5116 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5117 if these are used or defined, if BFD_ASSEMBLER.
5118 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5119 subseg_new split into two functions.
5120 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5122 * as.h (volatile): Don't define if already defined.
5123 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5125 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5126 declare with format attribute for -Wformat checking.
5128 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5130 * app.c, config/tc-*.c: Don't include read.h, since it is already
5133 * These are based on patches from Minh Tran-le
5134 <mtranle@paris.intellicorp.com>.
5135 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5136 obj_format coffbfd and gas_target i386coff for target.
5137 (i[34]86-*-isc*): New host (uses sysv).
5138 * config/i386aix.mt: Removed (no longer used).
5139 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5141 (LDFLAGS): Added, defined as -shlib.
5142 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5143 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5144 (DOT_LABEL_PREFIX): Define.
5145 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5146 name rather than L0\001.
5147 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5149 * symbols.c, symbols.h (local_bss_counter): Removed.
5150 * write.c (write_object_file): bss no longer uses
5151 local_bss_counter. Pass correct data and bss size to
5152 VMS_write_object_file.
5153 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
5154 argument, rather than using local_bss_counter.
5155 * config/tc-m88k.c (s_bss): Don't use local_bss_counter.
5156 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
5157 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
5158 (size_section): Restored sanity check.
5159 (do_relocs_for): Base section address on s_paddr rather than
5160 computing it. Adjust a29k R_IHIHALF special case to account for
5161 section paddr (used to require paddr to be zero). If there are no
5162 reclos, set s_relptr to 0. Set relocation size in object_headers.
5163 (fill_section): Always set s_vaddr here, removing
5164 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5165 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.

5172 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5173 set s_vaddr here. If string_byte_count remains 4, set it back to
5174 0, and only write strings out if there are some. Call
5175 fill_section before do_relocs_for and do_linenos_for.
5176 (obj_coff_section): Handle optional quoted second argument giving
5177 section characteristics.

5205 * config/obj-coff.h: Don't use #elif.
5207 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

5247 (yank_symbols): Don't merge labels.
5248 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5394 could be doing emulation.
5396 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5399 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5469 * Support for i386-sysv.
5470 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5508 * tc-z8k.c: lots of bug fixes
5510 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5512 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5513 #elif, since it is not supported by old compilers.
5514 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5515 couple of expressions in tc-m68k.c.
5517 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

5543 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5545 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5546 sections starting from zero, rather than making them consecutive.
5547 This makes subsequent reloc calculations easier, esp if the object
5548 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5549 allocate lcomm in .data rather than in .bss. It seems that some
5550 tools can't cope with a non-zero sized bss before linkage.

5573 * Makefile.in (install): if $(tooldir) exists, install as in
5576 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5578 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5579 .word is < -32768 or > 32767. The -J flag causes the error to be
5580 ignored. This is to catch over-sized switches generated by gcc on
5581 systems which don't support the broken .word hack.
5582 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5583 write.c (fixup_segment): check for signed .word overflow if
5584 WARN_SIGNED_OVERFLOW_WORD.
5586 * write.c (fixup_segment): fixed missing parens in expression
5587 checking for byte or word overflow.

5603 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5605 * input-scrub.c (input_scrub_push): call input_file_begin, not
5607 messages.c (as_perror): print ": " between the passed in error and
5608 the strerror, like perror does.
5610 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
5612 * Makefile.in: use gas_target instead of modifying target_cpu.
5613 From Steve Chamberlain:
5614 Makefile.in: Handle m68*-*-coff*.
5615 read.c, read.h: add mult argument to s_space
5617 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5618 Motorola and MIT syntax; gas can now assemble either type of

5626 (write_object_file) call fixup_mdeps
5627 (fixup_segment) set fx_subsy to 0.
5628 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5630 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5633 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5635 * Makefile.in (LIBS): Include opcode library.
5637 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5657 tc-i960.c (md_ri_to_chars): Always output bout object file in
5658 little endian byte order (used to use endianness of host).
5660 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5662 * config/tc-m68k.c (init_table): Now const. Always include 68851
5663 data, so that "bc" is available to 68040 cache instructions.
5664 Added "tt0", "tt1", and 68ec030 variants.
5665 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5666 (enum _register): Added TT0, TT1.
5667 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5668 line number correctly in "internal error" messages. Don't print
5669 architecture-mismatch message for operand errors.

5672 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5673 than install_operand.

5698 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5700 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5701 written with indirection on the last two operands, which can be
5702 either data or address registers. Added a new operand type 'r'
5703 which accepts either register type. Added '(' to notend stuff in
5704 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5723 their not having symbols associated.
5725 * tc-i960.c (norelax, instrument_branches): Default initializer is
5727 (linkrelax): Delete variable definition.

5814 processor/opcode mismatch, so reword the error message.
5815 (md_assemble): If no CPU has been set (even if FPU/PMMU
5816 characteristics have been), default to 68020. Don't need extra
5817 quotes around error string.

5821 * read.c (potable): Revert sac's incorrect change made Jul 13.

5899 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5901 * write.c (write_object_file): keep the fix_tail clean, which
5902 fixes a bug in -R where relocations were being lost.
5904 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5906 * configure.in: recognize m680x0 as having sun3 emulation mode for

5950 * write.c (write_object_file): For b.out format, round up section
5951 start addresses to match required alignment.
5953 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5955 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5956 where gcc looks for it.
5958 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5960 * Makefile.in: Changed some lines to be less confusing for some

6030 * expr.c (operand): if can't work out what sort of operand it is,
6031 then look through FLT_CHARS for a hint.
6033 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6035 * Makefile.in, configure.in: removed traces of namesubdir,

6037 copyrights to '92, changed some from Cygnus to FSF.
6039 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6040 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6041 copyrights to '92, changed some from Cygnus to FSF.
6043 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6045 * expr.c: If an expression is single comma, then return with
6046 SEG_ABSENT rather than an error - since the sparc front end does
6047 really strange things with things like fbge,a
6049 * as.h: include bfd.h if using many sections
6050 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6051 local labels didn't work.
6052 * listing.c (list_symbol_table): don't core dump when there's no
6054 * write.c, write.h: call fix_new with the right number of args on
6056 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6059 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6061 * app.c: MRI compatibility - allow single quote to start a string.
6062 * as.c: fix typo recently introduced.
6063 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6064 * expr.c: Much rewriting, to accomodate MRI syntax for
6065 expressions. Also easier to read now.
6066 * listing.c: Put back defuns
6067 * read.c: modified to accept MRI syntax, put back listing pseudo
6068 ops so that an assembler built with NO_LISTING ignores list ops
6070 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6071 machine is a SPARC or a 29K.
6072 * config/obj-aout.c: added s_sect pseudo op
6073 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6074 fill in the timestamp.
6075 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6076 anymore, define all the relocs which the tc-<x> bit will use so we
6077 can translate from them to the coff types.
6078 * config/tc-a29k.c: reloc_type isn't ane enum any more
6079 * config/tc-m68k.c: Added NO_RELOC definition.
6081 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6083 * Makefile.in: put header files before C source for TAGS; remove
6084 references to non-existent syscalls.h.
6086 * read.c, write.c subsegs.c: back out the .bss changes.
6088 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6090 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6094 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6096 * symbols.c (local_label_name): symbols now start with ^A.
6098 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6099 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6100 generate these sections. .align: will use NOP_OPCODE or 0
6101 for padding. This is just for being nice to the
6104 * expr.c (operand): changed to generate local label "\001L0"
6105 starting with a ^A so that it is recognized as a local label.
6107 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6109 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6110 i/o opcodes - inb, inw, outb and outw. string manipulation with
6111 att syntax - scmp, slod, smov, ssca, ssto.
6113 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6114 to just after .file .
6116 In obj_crawl_symbol_chain() where it tries to put the external
6117 symbols apart, with the condition:
6118 (!S_IS_DEFINED(symbolP) &&
6119 !S_IS_DEBUG(symbolP) &&
6120 !SF_GET_STATICS(symbolP))
6121 it was moving too many symbols out. So I switch it back to the
6123 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6125 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6126 so that we don't use the F_RELFLG which make the linker complain
6127 that somebody has stripped the relocation info.
6129 Also, the AIX ld program require that the relocation table
6130 is sorted by r_vaddr like the standard ATT assembler does.
6132 [he also changed the sizeof(struct ...)'s into the coff
6133 style FOOSZ macros. I'm not sure this is right, but I can't
6134 remember why. xoxorich.]
6136 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6138 * Makefile.in, configure.in, doc: use the doc. Build it, install

6143 * read.c: white space and comments only.
6145 * configure.in: use the new atof-ns32.c for ns32k.
6147 * write.c: comment change only.
6149 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6150 aren't yet integrated.
6152 * tc-i860.[hc]: blew off the dust. Something must still be done
6153 about conflicting relocation types.
6155 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6158 * tc-i960.c, tc-sparc.c: white space and comments only.
6160 * tc-a29k.h: delete duplicate macro definition.
6162 * new file atof-ns32k.c copied from hack's last unreleased gas.
6164 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6166 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6169 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6170 ChangeLog's prior to this are sketchy at best. I have logs.
6171 They just aren't ChangeLogs.
6175 version-control: never
