1424 still being worked on. Mark Elf configurations (except sparc and
1425 i386) as developmental. Deleted cases matching some generic names
1426 in favor of more specific names. (E.g., when we get Alpha

1444 for functions only used within tc-hppa.c, likewise for structures,
1445 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1446 conditional code in a few small places.
1448 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1449 structures, global variables, forward declarations together.

2604 * Extensive changes to permit symbols to contain any expression
2605 type and to delay the computation of the expression until the
2606 value is actually needed. This permits setting symbols to values
2607 calculated based on object code size. Expressions were changed to
2608 no longer be in a section, to stop the overloading of segment and
2609 expression type that previously occurred.
2611 * as.c (big_section, pass1_section, diff_section, absent_section):
2613 (expr_section): Added (used for dummy symbols which hold

2699 to pop back to it. Handle unquoted section name as well as quoted
2700 section name. Don't crash on invalid strings.

2722 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
2723 calculating opP->isiz; this permits the expression size to be
2724 determined as well, later on.
2726 * expr.c (clean_up_expression): Don't cancel the subtraction of
2729 * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R,

2738 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
2740 * read.c (float_cons): Simplified parsing logic. If
2741 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
2743 * symbols.c (colon): Rather than a special case for TC_HPPA,
2744 use new macro tc_frob_label.
2745 * config/tc-hppa.h (tc_frob_label): Define.
2747 * config/tc-mips.c: Many changes to support simple assembler

3903 source directory, if that's not the current directory.
3905 * configure.in (per-host): Accept MIPS host with BSD version

3931 avoid some redefinition complaints on some systems.
3932 (const, volatile): Don't need these conditionally defined if we
3933 use CONST and VOLATILE from ansidecl.h.
3934 (seg_name): Use CONST, not const.
3936 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3938 * config/tc-mips.c: Reindented to GNU standards.

3942 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3943 (fixup_segment): Add a29k special case; the linker is not prepared
3944 to see a segment offset here.

3949 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3951 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3952 srcdir, might be in objdir.

3971 * Makefile.in (targ-cpu.o): Depend on config.h.
3973 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3975 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3976 dropping a space immediately following an identifier.
3977 * expr.c, write.c: Rewrote assert expressions to not use multiple
3978 lines; I don't think that can be done portably.
3979 * config/tc-mips.c (macro): Use $AT if target register is zero in
3980 load instruction, which it can be for a floating point load.
3982 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4003 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4005 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4006 to be on a single line.

4054 prototypes for all static functions. Moved existing minimal
4055 debugging format support info #ifndef OBJ_ECOFF blocks.

4104 * make-gas.com: Find obstack.obj if it's not in the current
4106 * read.c (s_ignore): Don't declare is_end_of_line. It's
4107 redundant, and triggers a VMS gcc compiler bug.
4109 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4110 current segment as an argument. (Ignored in all cases but VMS.)
4111 All callers and definitions changed.

4240 * read.c: Don't include ctype.h.
4241 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
4242 for now; should be machine-dependent.

4408 md_relax_table): Use default zero initialization.
4409 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4410 latter, instead of selecting with preprocessor conditionals.
4412 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4414 * configure.in: recognise all sparclite variants

4424 * expr.c (operand): If character other than comma or newline is a
4425 logical end-of-line character, use the newline case.
4426 From Eric Youngdale:
4427 (operand): Set X_add_number field for floating-point numbers.
4428 (operand): Treat zero byte as end-of-operand.
4430 * configure.in (per-target): Look for with_bfd_assembler option.
4431 For now, only accept "no", until the merge is done.
4433 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4434 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4440 * expr.c: Add "const" modifier to hex_value.
4441 * symbols.c: Finish conversion to S_* macros in the VMS only
4442 parts of the program. Add "const" modifier to
4443 md_[long,short]_jump_size. Remove declaration of const_flag
4444 (which will be declared in obj-vms.h).
4445 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4446 Fix arguments to VMS_write_object_file.
4447 * config-gas.com: New file. Script for VMS systems to set up the
4448 configuration to build gas for VMS, and create config.status.
4449 * make-gas.com: Redone to work with new scheme.
4450 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4452 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

4455 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4456 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4457 types of malformed stabs. Change parsing algorithm so that we are
4458 more certain of having all of the information that we need on hand.
4459 * obj-vms.c (final_forward_reference): New function, used to help
4460 resolve the data types of as many struct elements as possible
4461 when some part of the struct is not fully defined by the compiler.

4464 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4465 as symbols as well in the object file. Look for external functions
4466 that start with "__vt.", and turn them into variables, since the
4467 g++ compiler is incapable of doing this.
4468 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4470 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4471 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4472 have the name of the source file yet.
4473 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4475 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4477 * read.c (s_data): Always use "data_section", since it'll map to
4478 SEG_DATA or SEG_E1 if needed.
4479 (s_lcomm): Likewise with bss_section.
4480 (s_fill): Use memset, not bzero.
4482 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4504 (big_section, reg_section, pass1_section, diff_section,
4505 absent_section, text_section, data_section, bss_section): If
4506 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4507 mapping to segT enum values.
4508 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4509 if these are used or defined, if BFD_ASSEMBLER.
4510 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4511 subseg_new split into two functions.
4512 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4514 * as.h (volatile): Don't define if already defined.
4515 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4517 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4518 declare with format attribute for -Wformat checking.
4520 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4522 * app.c, config/tc-*.c: Don't include read.h, since it is already
4525 * These are based on patches from Minh Tran-le
4526 <mtranle@paris.intellicorp.com>.
4527 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4528 obj_format coffbfd and gas_target i386coff for target.
4529 (i[34]86-*-isc*): New host (uses sysv).
4530 * config/i386aix.mt: Removed (no longer used).
4531 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4533 (LDFLAGS): Added, defined as -shlib.
4534 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4535 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4536 (DOT_LABEL_PREFIX): Define.
4537 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4538 name rather than L0\001.
4539 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4541 * symbols.c, symbols.h (local_bss_counter): Removed.
4542 * write.c (write_object_file): bss no longer uses

4550 (size_section): Restored sanity check.
4551 (do_relocs_for): Base section address on s_paddr rather than
4552 computing it. Adjust a29k R_IHIHALF special case to account for
4553 section paddr (used to require paddr to be zero). If there are no
4554 reclos, set s_relptr to 0. Set relocation size in object_headers.
4555 (fill_section): Always set s_vaddr here, removing
4556 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4557 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4558 Set STYP_INFO for .comment.
4559 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4560 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4562 H_{SET,GET}_* macros.
4563 (do_linenos_for): Set lineno size in object_headers.
4564 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4565 set s_vaddr here. If string_byte_count remains 4, set it back to
4566 0, and only write strings out if there are some. Call
4567 fill_section before do_relocs_for and do_linenos_for.
4568 (obj_coff_section): Handle optional quoted second argument giving
4569 section characteristics.
4570 (obj_coff_bss): Added to handle .bss.
4571 (obj_coff_ident): Added to handle .ident (puts string in .comment

4591 (do_scrub_next_char): For \", return " not '.
4592 (symbol_chars): Now const.
4594 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4595 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4597 * config/obj-coff.h: Don't use #elif.
4599 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4600 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4602 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4604 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4624 SEG_BSS, fill with NOP_OPCODE.
4625 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4626 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4627 using ZERO_BASED_SEGMENTS.
4628 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4629 never set segment address for SEG_E2 (.bss) and don't write out
4630 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4631 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4632 definitions, and don't merge tags with non-tags. Check for .bf
4633 rather than just checking whether the second character is b and
4634 the third character is f.
4635 (obj_coff_val): gcc can generate values which we don't handle
4636 correctly; discard information for now, since it only affects the
4637 debugging information.
4638 (tag_find_or_name): Don't insert tags in the symbol table.
4639 (yank_symbols): Don't merge labels.
4640 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4660 power-of-two alignment for .align.
4662 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
4663 and leave everything else alone.

4786 could be doing emulation.
4788 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4791 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4904 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4905 #elif, since it is not supported by old compilers.
4906 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4907 couple of expressions in tc-m68k.c.
4909 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4911 * read.c (cons): If NO_RELOC is defined, use it.

4937 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4938 sections starting from zero, rather than making them consecutive.
4939 This makes subsequent reloc calculations easier, esp if the object
4940 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4941 allocate lcomm in .data rather than in .bss. It seems that some
4942 tools can't cope with a non-zero sized bss before linkage.
4944 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4946 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4965 * Makefile.in (install): if $(tooldir) exists, install as in
4968 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4970 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4971 .word is < -32768 or > 32767. The -J flag causes the error to be
4972 ignored. This is to catch over-sized switches generated by gcc on
4973 systems which don't support the broken .word hack.
4974 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4975 write.c (fixup_segment): check for signed .word overflow if
4976 WARN_SIGNED_OVERFLOW_WORD.

4995 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4997 * input-scrub.c (input_scrub_push): call input_file_begin, not
4999 messages.c (as_perror): print ": " between the passed in error and
5000 the strerror, like perror does.

5005 From Steve Chamberlain:
5006 Makefile.in: Handle m68*-*-coff*.
5007 read.c, read.h: add mult argument to s_space
5009 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5010 Motorola and MIT syntax; gas can now assemble either type of

5019 (fixup_segment) set fx_subsy to 0.
5020 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5022 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5025 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5027 * Makefile.in (LIBS): Include opcode library.

5052 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5054 * config/tc-m68k.c (init_table): Now const. Always include 68851
5055 data, so that "bc" is available to 68040 cache instructions.
5056 Added "tt0", "tt1", and 68ec030 variants.
5057 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5058 (enum _register): Added TT0, TT1.
5059 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5060 line number correctly in "internal error" messages. Don't print
5061 architecture-mismatch message for operand errors.
5063 From Colin Smith (colin@wrs.com):
5064 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5065 than install_operand.

5081 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5082 so that we can assemble hand-written libgcc code.

5086 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5087 has already been formatted (but may still contain %-characters).
5090 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5092 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5093 written with indirection on the last two operands, which can be
5094 either data or address registers. Added a new operand type 'r'
5095 which accepts either register type. Added '(' to notend stuff in
5096 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5098 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

5114 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5115 their not having symbols associated.
5117 * tc-i960.c (norelax, instrument_branches): Default initializer is
5119 (linkrelax): Delete variable definition.

5143 being used with args swapped, causing occasional lossage when
5144 refilling buffers after an include file.

5154 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5155 selected architecture, print a message saying so and listing what

5293 * write.c (write_object_file): keep the fix_tail clean, which
5294 fixes a bug in -R where relocations were being lost.
5296 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5298 * configure.in: recognize m680x0 as having sun3 emulation mode for

5345 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5347 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5348 where gcc looks for it.
5350 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5352 * Makefile.in: Changed some lines to be less confusing for some

5418 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5420 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5422 * expr.c (operand): if can't work out what sort of operand it is,
5423 then look through FLT_CHARS for a hint.
5425 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5427 * Makefile.in, configure.in: removed traces of namesubdir,

5429 copyrights to '92, changed some from Cygnus to FSF.
5431 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5432 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5433 copyrights to '92, changed some from Cygnus to FSF.
5435 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5437 * expr.c: If an expression is single comma, then return with
5438 SEG_ABSENT rather than an error - since the sparc front end does
5439 really strange things with things like fbge,a
5441 * as.h: include bfd.h if using many sections
5442 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5443 local labels didn't work.
5444 * listing.c (list_symbol_table): don't core dump when there's no
5446 * write.c, write.h: call fix_new with the right number of args on
5448 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5451 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5453 * app.c: MRI compatibility - allow single quote to start a string.
5454 * as.c: fix typo recently introduced.
5455 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5456 * expr.c: Much rewriting, to accomodate MRI syntax for
5457 expressions. Also easier to read now.
5458 * listing.c: Put back defuns
5459 * read.c: modified to accept MRI syntax, put back listing pseudo
5460 ops so that an assembler built with NO_LISTING ignores list ops
5462 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5463 machine is a SPARC or a 29K.
5464 * config/obj-aout.c: added s_sect pseudo op
5465 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5466 fill in the timestamp.
5467 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5468 anymore, define all the relocs which the tc-<x> bit will use so we
5469 can translate from them to the coff types.
5470 * config/tc-a29k.c: reloc_type isn't ane enum any more
5471 * config/tc-m68k.c: Added NO_RELOC definition.
5473 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5475 * Makefile.in: put header files before C source for TAGS; remove
5476 references to non-existent syscalls.h.
5478 * read.c, write.c subsegs.c: back out the .bss changes.
5480 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5482 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5486 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5488 * symbols.c (local_label_name): symbols now start with ^A.
5490 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5491 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5492 generate these sections. .align: will use NOP_OPCODE or 0
5493 for padding. This is just for being nice to the
5496 * expr.c (operand): changed to generate local label "\001L0"
5497 starting with a ^A so that it is recognized as a local label.
5499 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5501 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5502 i/o opcodes - inb, inw, outb and outw. string manipulation with
5503 att syntax - scmp, slod, smov, ssca, ssto.
5505 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5506 to just after .file .
5508 In obj_crawl_symbol_chain() where it tries to put the external
5509 symbols apart, with the condition:
5510 (!S_IS_DEFINED(symbolP) &&
5511 !S_IS_DEBUG(symbolP) &&
5512 !SF_GET_STATICS(symbolP))
5513 it was moving too many symbols out. So I switch it back to the
5515 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5517 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5518 so that we don't use the F_RELFLG which make the linker complain
5519 that somebody has stripped the relocation info.
5521 Also, the AIX ld program require that the relocation table
5522 is sorted by r_vaddr like the standard ATT assembler does.
5524 [he also changed the sizeof(struct ...)'s into the coff
5525 style FOOSZ macros. I'm not sure this is right, but I can't
5526 remember why. xoxorich.]
5528 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5530 * Makefile.in, configure.in, doc: use the doc. Build it, install

5535 * read.c: white space and comments only.
5537 * configure.in: use the new atof-ns32.c for ns32k.
5539 * write.c: comment change only.
5541 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5542 aren't yet integrated.
5544 * tc-i860.[hc]: blew off the dust. Something must still be done
5545 about conflicting relocation types.
5547 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5550 * tc-i960.c, tc-sparc.c: white space and comments only.
5552 * tc-a29k.h: delete duplicate macro definition.
5554 * new file atof-ns32k.c copied from hack's last unreleased gas.
5556 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5558 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5561 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5562 ChangeLog's prior to this are sketchy at best. I have logs.
5563 They just aren't ChangeLogs.
