1453 in favor of more specific names. (E.g., when we get Alpha
1454 support, we'll still only support VMS for Vax.)
1456 * config/tc-sparc.h (md_end): New macro.
1457 * config/tc-sparc.c (md_end): Function deleted.
1458 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

1468 against placing additional object-file dependent code here. Warn
1469 against contaminating all of GAS with the internals of tc-hppa.c
1470 through inclusion of tc-hppa.h. Delete all forward declarations
1471 for functions only used within tc-hppa.c, likewise for structures,
1472 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1473 conditional code in a few small places.
1475 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1476 structures, global variables, forward declarations together.

1479 into a few places. Make all functions and variables which
1480 are only used within tc-hppa.c static. PARAMize all functions.
1481 Add comments to functions. Delete unused functions, variables,
1482 #defines, etc. Delete unused members within structures. Delete
1483 ldil;ble hacks -- it is believed they were installed to work
1484 around old gas bugs. Avoid using mixed case for local
1485 functions, variables, and structures. Fix formatting problems
1486 not found by GNU-indent. Add FIXME notices for things which
1487 should be worked on the near future. Delete lots of old
1488 useless (1.36 PA-SOM) code.

1517 a multiple of the section alignment rather than always a
1520 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2631 * Extensive changes to permit symbols to contain any expression
2632 type and to delay the computation of the expression until the
2633 value is actually needed. This permits setting symbols to values
2634 calculated based on object code size. Expressions were changed to
2635 no longer be in a section, to stop the overloading of segment and
2636 expression type that previously occurred.
2638 * as.c (big_section, pass1_section, diff_section, absent_section):

3930 source directory, if that's not the current directory.
3932 * configure.in (per-host): Accept MIPS host with BSD version

3958 avoid some redefinition complaints on some systems.
3959 (const, volatile): Don't need these conditionally defined if we
3960 use CONST and VOLATILE from ansidecl.h.
3961 (seg_name): Use CONST, not const.
3963 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3965 * config/tc-mips.c: Reindented to GNU standards.

3969 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3970 (fixup_segment): Add a29k special case; the linker is not prepared
3971 to see a segment offset here.
3973 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3976 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3978 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3979 srcdir, might be in objdir.

3994 bignums, but don't emit error message.
3996 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3998 * Makefile.in (targ-cpu.o): Depend on config.h.
4000 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4002 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4003 dropping a space immediately following an identifier.
4004 * expr.c, write.c: Rewrote assert expressions to not use multiple
4005 lines; I don't think that can be done portably.
4006 * config/tc-mips.c (macro): Use $AT if target register is zero in
4007 load instruction, which it can be for a floating point load.
4009 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4030 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4032 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4033 to be on a single line.
4035 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4037 * Makefile.in (config.h): Create file, writing out definitions of

4081 prototypes for all static functions. Moved existing minimal
4082 debugging format support info #ifndef OBJ_ECOFF blocks.

4131 * make-gas.com: Find obstack.obj if it's not in the current
4133 * read.c (s_ignore): Don't declare is_end_of_line. It's
4134 redundant, and triggers a VMS gcc compiler bug.
4136 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4137 current segment as an argument. (Ignored in all cases but VMS.)
4138 All callers and definitions changed.

4156 argument to s_ignore. Put "#if 0" around unused code.
4157 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
4158 Call elf_xstabs for .stabs and .xstabs operators.

4435 md_relax_table): Use default zero initialization.
4436 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4437 latter, instead of selecting with preprocessor conditionals.
4439 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4441 * configure.in: recognise all sparclite variants

4451 * expr.c (operand): If character other than comma or newline is a
4452 logical end-of-line character, use the newline case.
4453 From Eric Youngdale:
4454 (operand): Set X_add_number field for floating-point numbers.
4455 (operand): Treat zero byte as end-of-operand.
4457 * configure.in (per-target): Look for with_bfd_assembler option.
4458 For now, only accept "no", until the merge is done.
4460 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4461 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4463 * read.c: Finish conversion to S_* macros in the VMS only
4464 parts of the program. Add "const" modifier to hex_value.
4465 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4467 * expr.c: Add "const" modifier to hex_value.
4468 * symbols.c: Finish conversion to S_* macros in the VMS only
4469 parts of the program. Add "const" modifier to
4470 md_[long,short]_jump_size. Remove declaration of const_flag
4471 (which will be declared in obj-vms.h).
4472 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4473 Fix arguments to VMS_write_object_file.
4474 * config-gas.com: New file. Script for VMS systems to set up the
4475 configuration to build gas for VMS, and create config.status.
4476 * make-gas.com: Redone to work with new scheme.
4477 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4479 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4480 will swap bytes if needed on a big endian system. Use throughout
4482 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4483 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4484 types of malformed stabs. Change parsing algorithm so that we are
4485 more certain of having all of the information that we need on hand.
4486 * obj-vms.c (final_forward_reference): New function, used to help
4487 resolve the data types of as many struct elements as possible
4488 when some part of the struct is not fully defined by the compiler.

4491 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4492 as symbols as well in the object file. Look for external functions
4493 that start with "__vt.", and turn them into variables, since the
4494 g++ compiler is incapable of doing this.
4495 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4497 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4498 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4499 have the name of the source file yet.
4500 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4502 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4504 * read.c (s_data): Always use "data_section", since it'll map to
4505 SEG_DATA or SEG_E1 if needed.
4506 (s_lcomm): Likewise with bss_section.
4507 (s_fill): Use memset, not bzero.
4509 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4531 (big_section, reg_section, pass1_section, diff_section,
4532 absent_section, text_section, data_section, bss_section): If
4533 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4534 mapping to segT enum values.
4535 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4536 if these are used or defined, if BFD_ASSEMBLER.
4537 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4538 subseg_new split into two functions.
4539 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4541 * as.h (volatile): Don't define if already defined.
4542 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4544 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4545 declare with format attribute for -Wformat checking.
4547 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4549 * app.c, config/tc-*.c: Don't include read.h, since it is already
4552 * These are based on patches from Minh Tran-le
4553 <mtranle@paris.intellicorp.com>.
4554 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4555 obj_format coffbfd and gas_target i386coff for target.
4556 (i[34]86-*-isc*): New host (uses sysv).
4557 * config/i386aix.mt: Removed (no longer used).
4558 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4560 (LDFLAGS): Added, defined as -shlib.
4561 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4562 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4563 (DOT_LABEL_PREFIX): Define.
4564 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4565 name rather than L0\001.
4566 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4568 * symbols.c, symbols.h (local_bss_counter): Removed.
4569 * write.c (write_object_file): bss no longer uses

4577 (size_section): Restored sanity check.
4578 (do_relocs_for): Base section address on s_paddr rather than
4579 computing it. Adjust a29k R_IHIHALF special case to account for
4580 section paddr (used to require paddr to be zero). If there are no
4581 reclos, set s_relptr to 0. Set relocation size in object_headers.
4582 (fill_section): Always set s_vaddr here, removing
4583 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4584 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4585 Set STYP_INFO for .comment.
4586 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4587 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4589 H_{SET,GET}_* macros.
4590 (do_linenos_for): Set lineno size in object_headers.
4591 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4592 set s_vaddr here. If string_byte_count remains 4, set it back to
4593 0, and only write strings out if there are some. Call
4594 fill_section before do_relocs_for and do_linenos_for.
4595 (obj_coff_section): Handle optional quoted second argument giving
4596 section characteristics.
4597 (obj_coff_bss): Added to handle .bss.
4598 (obj_coff_ident): Added to handle .ident (puts string in .comment

4618 (do_scrub_next_char): For \", return " not '.
4619 (symbol_chars): Now const.
4621 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4622 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4624 * config/obj-coff.h: Don't use #elif.
4626 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4627 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4629 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4631 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4651 SEG_BSS, fill with NOP_OPCODE.
4652 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4653 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4654 using ZERO_BASED_SEGMENTS.
4655 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4656 never set segment address for SEG_E2 (.bss) and don't write out
4657 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4658 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4659 definitions, and don't merge tags with non-tags. Check for .bf
4660 rather than just checking whether the second character is b and
4661 the third character is f.
4662 (obj_coff_val): gcc can generate values which we don't handle
4663 correctly; discard information for now, since it only affects the
4664 debugging information.
4665 (tag_find_or_name): Don't insert tags in the symbol table.
4666 (yank_symbols): Don't merge labels.
4667 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4686 * config/tc-i386.c (md_pseudo_table): For 386bsd and linux, do
4687 power-of-two alignment for .align.
4689 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
4690 and leave everything else alone.
4692 Fri Dec 4 16:58:42 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

4813 could be doing emulation.
4815 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4818 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4847 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4849 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4850 constant will not fit in an immediate field.
4851 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4888 * Support for i386-sysv.
4889 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4927 * tc-z8k.c: lots of bug fixes
4929 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4931 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4932 #elif, since it is not supported by old compilers.
4933 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4934 couple of expressions in tc-m68k.c.
4936 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4938 * read.c (cons): If NO_RELOC is defined, use it.
4940 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4942 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4944 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4945 local labels to start with a .) and set REGISTER_PREFIX to %.
4946 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4948 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4962 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4964 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4965 sections starting from zero, rather than making them consecutive.
4966 This makes subsequent reloc calculations easier, esp if the object
4967 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4968 allocate lcomm in .data rather than in .bss. It seems that some
4969 tools can't cope with a non-zero sized bss before linkage.
4971 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4973 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4992 * Makefile.in (install): if $(tooldir) exists, install as in
4995 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4997 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4998 .word is < -32768 or > 32767. The -J flag causes the error to be
4999 ignored. This is to catch over-sized switches generated by gcc on
5000 systems which don't support the broken .word hack.
5001 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5002 write.c (fixup_segment): check for signed .word overflow if
5003 WARN_SIGNED_OVERFLOW_WORD.
5005 * write.c (fixup_segment): fixed missing parens in expression
5006 checking for byte or word overflow.

5022 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5024 * input-scrub.c (input_scrub_push): call input_file_begin, not
5026 messages.c (as_perror): print ": " between the passed in error and
5027 the strerror, like perror does.

5032 From Steve Chamberlain:
5033 Makefile.in: Handle m68*-*-coff*.
5034 read.c, read.h: add mult argument to s_space
5036 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5037 Motorola and MIT syntax; gas can now assemble either type of

5046 (fixup_segment) set fx_subsy to 0.
5047 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5049 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5052 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5054 * Makefile.in (LIBS): Include opcode library.
5056 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5079 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5081 * config/tc-m68k.c (init_table): Now const. Always include 68851
5082 data, so that "bc" is available to 68040 cache instructions.
5083 Added "tt0", "tt1", and 68ec030 variants.
5084 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5085 (enum _register): Added TT0, TT1.
5086 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5087 line number correctly in "internal error" messages. Don't print
5088 architecture-mismatch message for operand errors.
5090 From Colin Smith (colin@wrs.com):
5091 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5092 than install_operand.

5108 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5109 so that we can assemble hand-written libgcc code.

5113 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5114 has already been formatted (but may still contain %-characters).
5117 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5119 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5120 written with indirection on the last two operands, which can be
5121 either data or address registers. Added a new operand type 'r'
5122 which accepts either register type. Added '(' to notend stuff in
5123 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5125 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

5139 (relax_align): If linkrelax, provide extra padding.
5141 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5142 their not having symbols associated.
5144 * tc-i960.c (norelax, instrument_branches): Default initializer is
5146 (linkrelax): Delete variable definition.

5170 being used with args swapped, causing occasional lossage when
5171 refilling buffers after an include file.

5175 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
5176 version. Discard bogus DONTDEF version.

5179 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
5181 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5182 selected architecture, print a message saying so and listing what

5233 processor/opcode mismatch, so reword the error message.
5234 (md_assemble): If no CPU has been set (even if FPU/PMMU
5235 characteristics have been), default to 68020. Don't need extra
5236 quotes around error string.

5318 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5320 * write.c (write_object_file): keep the fix_tail clean, which
5321 fixes a bug in -R where relocations were being lost.
5323 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5325 * configure.in: recognize m680x0 as having sun3 emulation mode for

5370 start addresses to match required alignment.
5372 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5374 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5375 where gcc looks for it.
5377 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5379 * Makefile.in: Changed some lines to be less confusing for some

5419 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
5421 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

5445 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5447 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5449 * expr.c (operand): if can't work out what sort of operand it is,
5450 then look through FLT_CHARS for a hint.
5452 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5454 * Makefile.in, configure.in: removed traces of namesubdir,
5455 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5456 copyrights to '92, changed some from Cygnus to FSF.
5458 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5459 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5460 copyrights to '92, changed some from Cygnus to FSF.
5462 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5464 * expr.c: If an expression is single comma, then return with
5465 SEG_ABSENT rather than an error - since the sparc front end does
5466 really strange things with things like fbge,a
5468 * as.h: include bfd.h if using many sections
5469 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5470 local labels didn't work.
5471 * listing.c (list_symbol_table): don't core dump when there's no
5473 * write.c, write.h: call fix_new with the right number of args on
5475 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5478 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5480 * app.c: MRI compatibility - allow single quote to start a string.
5481 * as.c: fix typo recently introduced.
5482 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5483 * expr.c: Much rewriting, to accomodate MRI syntax for
5484 expressions. Also easier to read now.
5485 * listing.c: Put back defuns
5486 * read.c: modified to accept MRI syntax, put back listing pseudo
5487 ops so that an assembler built with NO_LISTING ignores list ops
5489 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5490 machine is a SPARC or a 29K.
5491 * config/obj-aout.c: added s_sect pseudo op
5492 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5493 fill in the timestamp.
5494 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5495 anymore, define all the relocs which the tc-<x> bit will use so we
5496 can translate from them to the coff types.
5497 * config/tc-a29k.c: reloc_type isn't ane enum any more
5498 * config/tc-m68k.c: Added NO_RELOC definition.
5500 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5502 * Makefile.in: put header files before C source for TAGS; remove
5503 references to non-existent syscalls.h.
5505 * read.c, write.c subsegs.c: back out the .bss changes.
5507 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5509 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5513 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5515 * symbols.c (local_label_name): symbols now start with ^A.
5517 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5518 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5519 generate these sections. .align: will use NOP_OPCODE or 0
5520 for padding. This is just for being nice to the
5523 * expr.c (operand): changed to generate local label "\001L0"
5524 starting with a ^A so that it is recognized as a local label.
5526 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5528 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5529 i/o opcodes - inb, inw, outb and outw. string manipulation with
5530 att syntax - scmp, slod, smov, ssca, ssto.
5532 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5533 to just after .file .
5535 In obj_crawl_symbol_chain() where it tries to put the external
5536 symbols apart, with the condition:
5537 (!S_IS_DEFINED(symbolP) &&
5538 !S_IS_DEBUG(symbolP) &&
5539 !SF_GET_STATICS(symbolP))
5540 it was moving too many symbols out. So I switch it back to the
5542 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5544 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5545 so that we don't use the F_RELFLG which make the linker complain
5546 that somebody has stripped the relocation info.
5548 Also, the AIX ld program require that the relocation table
5549 is sorted by r_vaddr like the standard ATT assembler does.
5551 [he also changed the sizeof(struct ...)'s into the coff
5552 style FOOSZ macros. I'm not sure this is right, but I can't
5553 remember why. xoxorich.]
5555 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5557 * Makefile.in, configure.in, doc: use the doc. Build it, install

5562 * read.c: white space and comments only.
5564 * configure.in: use the new atof-ns32.c for ns32k.
5566 * write.c: comment change only.
5568 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5569 aren't yet integrated.
5571 * tc-i860.[hc]: blew off the dust. Something must still be done
5572 about conflicting relocation types.
5574 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5577 * tc-i960.c, tc-sparc.c: white space and comments only.
5579 * tc-a29k.h: delete duplicate macro definition.
5581 * new file atof-ns32k.c copied from hack's last unreleased gas.
5583 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5585 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5588 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5589 ChangeLog's prior to this are sketchy at best. I have logs.
5590 They just aren't ChangeLogs.
