138 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
139 flag rather than signedp field. Only permit extended range if
140 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
141 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
143 * config/tc-ppc.c (ppc_size): New static variable.
144 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.

166 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
167 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
168 and -many (all architectures).

178 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
179 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
181 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
182 branch with an instruction that uses $at, in case the branch is
184 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
185 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
186 to make it pcrel_offset.
187 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
188 reloc->address; another gruesome hack to get gas reloc handling to
191 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
193 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

197 (md_assemble): Call it.
198 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
200 (lituse_pending): New variable. Set by anything that generates a
201 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
202 tested by code that might want to emit a LITUSE reloc.
203 (emit_unaligned_io): New function. Currently calls md_assemble,
204 but it should eventually be converted to generate the insn itself
205 and call emit_insn directly.
206 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
207 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
208 emit_bis_r): Likewise.

219 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
220 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

236 (load_address): Handle EMBEDDED_PIC.
237 (macro): Handle EMBEDDED_PIC in all PIC cases.
238 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
239 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
240 -non_shared to use NO_PIC (this is how the Irix 5 assembler
241 works). Do not permit -G with SVR4_PIC.
242 (s_abicalls): Warn if -G was used, and force -G 0.
243 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
244 anything but a.out, not just for ELF. For ECOFF, don't generate a
245 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
247 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
249 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

255 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
257 * Makefile.in (config-stamp): If `defs' is defined, emit a
258 preprocessor directive to create a macro named by this value into
259 config.new; don't explicitly go for BFD_ASSEMBLER.
260 * configure.in: Define `defs', not `BFDDEF'. Set it to
261 MANY_SEGMENTS for any obj-coffbfd target.
262 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
263 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
265 (LOCAL_LOADLIBES): Deleted.
266 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
267 * config/m88kcoff.mt (TDEFINES): Ditto.

293 bfd_set_symtab is called.
294 (dump_section_relocs): Note whether a symbol is a section symbol
296 (adjust_reloc_syms): For now, always supply an absolute symbol for
297 fixups without symbols but not yet `done'. Use section_symbol to
298 get the symbol, instead of going directly for abs_symbol.
299 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
300 reloc is not a section symbol and is not in the symbol table.
301 (set_symtab): New function, broken out from write_object_file.
302 Counts symbol table instead of relying on an earlier count.
303 (write_object_file): Call set_symtab, but do it after potentially
304 invoking the *_frob_file macros. Don't bother counting symbols.
305 Call symbol_remove, instead of expanding it in place. Moved the
306 conditionalized `object_file_size' declaration down to
307 conditionalized block where it's used. When using the absolute
308 symbol for a fixup without a symbol, set sy_used_in_reloc.
309 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
310 the correct symbol for the absolute section.
312 * subsegs.c (section_symbol): Use symbol_new instead of
313 symbol_make, since we may want it to go into the symbol table.
314 Make the new symbol have internal linkage. If
315 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
316 symbol with the newly created GAS symbol.
317 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
318 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

325 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
326 (sparc_ip, label "immediate"): Reject constants for pcrel
327 instructions only if the relocation type indicates a "call"
328 instruction and the offset is within range of a "jmpl %g0". If
329 it's not in range, use the absolute section symbol plus an offset.
330 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
332 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
334 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
337 * configure.in: Eliminated all targets using obj-coff but not
338 defining BFD_ASSEMBLER; I think all such targets that are
339 supported will be matched by real CPU-OS combinations earlier in
341 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
342 some comments about the dpx2 configuration, but left it disabled,
343 since it couldn't be reached before.
344 (target a29k-amd-ebmonold): Deleted.
346 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
348 * config/tc-hppa.c (pa_import): Correctly handle importing of an

354 the 'j' operand if there are no further alternatives for this
357 * config/obj-coffbfd.c (adjust_stab_section): Initialize
358 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
359 is not SEG_UNKNOWN rather than checking whether it is >= 0.
361 * config/tc-mips.c (mips_align): Take new argument, label, and use
362 it instead of global insn_label.
363 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
364 call to mips_emit_delay and pass it to mips_align.
366 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
368 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
370 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
371 argument to a .callinfo directive. Don't loop forever on errors.
373 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
374 use pre-defined registers as arguments.

378 * write.c (write_object_file): Check both S_IS_LOCAL and
379 S_IS_EXTERNAL when deciding whether to discard a symbol.
381 * config-gas.com: Scan Makefile.in, not version.c, for current
382 version number. Delete all versions of temp files when finished
383 with them. Create config.h.
385 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
386 values to reduce number of lookups with S_GET_VALUE. Skip debug

388 holger@botbso.rhein-main.de.)
389 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
390 field. (Also from Holger Teutsch.) Watch for a would-be register
391 mask that spans frags.
393 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
394 this_base, not line_base. (Patch from Andreas Arens,
395 ari@obelix.av.rwth-aachen.de.)
397 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
398 look local if they're exported or undefined. Used to be done for
401 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
402 Get it from the looked-up symbol, instead of using the string from
403 the input stream, which is no longer null-terminated.

405 (lex_type): Use it for `%'.
407 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
408 (vip_op): Now static, and returns void. Callers changed. Added

468 (obj_coff_section): Declare.
469 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
470 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this
471 work. It still doesn't. It now fails to compile, instead of
472 silently compiling to do nothing.
473 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
475 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

2188 pass new argument for i, j and o cases.

2410 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2411 the table, require that the one without bit 0x1000000 set come
2412 first. Require further that it be case 'b' or 'P'. The a29k
2413 opcode table already meets these constraints.
2414 (machine_ip): When handling case 'i' or 'A', make sure that the

2463 as.info* even if they're in $(srcdir) (e.g., for FSF
2466 * write.c (write_relocs): For relocs that are pc_relative and
2467 pcrel_offset and not partial_inplace, adjust reloc->addend to

2523 for keeping or rejecting configurations still under development;
2524 default is to assume production environment, and reject configs
2525 still being worked on. Mark Elf configurations (except sparc and
2526 i386) as developmental. Deleted cases matching some generic names
2527 in favor of more specific names. (E.g., when we get Alpha

2544 through inclusion of tc-hppa.h. Delete all forward declarations
2545 for functions only used within tc-hppa.c, likewise for structures,
2546 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2547 conditional code in a few small places.
2549 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2550 structures, global variables, forward declarations together.

2552 conditional code -- try to group conditional code together
2553 into a few places. Make all functions and variables which
2554 are only used within tc-hppa.c static. PARAMize all functions.
2555 Add comments to functions. Delete unused functions, variables,
2556 #defines, etc. Delete unused members within structures. Delete
2557 ldil;ble hacks -- it is believed they were installed to work
2558 around old gas bugs. Avoid using mixed case for local
2559 functions, variables, and structures. Fix formatting problems
2560 not found by GNU-indent. Add FIXME notices for things which
2561 should be worked on the near future. Delete lots of old
2562 useless (1.36 PA-SOM) code.

2579 * config/tc-hppa.c: Likewise.
2581 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2582 of elf32_symbol_type.
2583 (pa_export_args): Likewise.

2590 * config/tc-hppa.c: (md_section_align): Align all sections to
2591 a multiple of the section alignment rather than always a
2594 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2635 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2637 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2638 ELF, since the ELF object format does not have these type of
2639 relocations. Change the abort into as as_bad and return
2640 BFD_RELOC_NONE to silence compiler warnings.
2641 (md_assemble): Keep track of the instruction size. Allow white
2642 space between the $ and the constant for compatibility with older
2643 gases and other assemblers.
2644 (i386_operand): Skip spaces between $ and expression.
2645 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

5032 avoid some redefinition complaints on some systems.

5043 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

5050 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5052 * Makefile.in: add dvi target; as-$(config).texinfo might live in

5077 dropping a space immediately following an identifier.

5079 lines; I don't think that can be done portably.
5080 * config/tc-mips.c (macro): Use $AT if target register is zero in
5081 load instruction, which it can be for a floating point load.

5104 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5106 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

5207 * read.c (s_ignore): Don't declare is_end_of_line. It's
5208 redundant, and triggers a VMS gcc compiler bug.

5529 (operand): Treat zero byte as end-of-operand.
5531 * configure.in (per-target): Look for with_bfd_assembler option.
5532 For now, only accept "no", until the merge is done.
5534 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5535 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5541 * expr.c: Add "const" modifier to hex_value.
5542 * symbols.c: Finish conversion to S_* macros in the VMS only
5543 parts of the program. Add "const" modifier to
5544 md_[long,short]_jump_size. Remove declaration of const_flag
5545 (which will be declared in obj-vms.h).
5546 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5547 Fix arguments to VMS_write_object_file.
5548 * config-gas.com: New file. Script for VMS systems to set up the

5608 mapping to segT enum values.
5609 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5610 if these are used or defined, if BFD_ASSEMBLER.
5611 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5612 subseg_new split into two functions.
5613 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5615 * as.h (volatile): Don't define if already defined.
5616 (had_errors, had_warnings): Provide prototypes for ANSI C even if

5627 <mtranle@paris.intellicorp.com>.
5628 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5629 obj_format coffbfd and gas_target i386coff for target.
5630 (i[34]86-*-isc*): New host (uses sysv).
5631 * config/i386aix.mt: Removed (no longer used).
5632 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5634 (LDFLAGS): Added, defined as -shlib.
5635 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5636 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5637 (DOT_LABEL_PREFIX): Define.
5638 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5639 name rather than L0\001.
5640 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5642 * symbols.c, symbols.h (local_bss_counter): Removed.
5643 * write.c (write_object_file): bss no longer uses
5644 local_bss_counter. Pass correct data and bss size to
5645 VMS_write_object_file.

5651 (size_section): Restored sanity check.
5652 (do_relocs_for): Base section address on s_paddr rather than
5653 computing it. Adjust a29k R_IHIHALF special case to account for
5654 section paddr (used to require paddr to be zero). If there are no
5655 reclos, set s_relptr to 0. Set relocation size in object_headers.
5656 (fill_section): Always set s_vaddr here, removing
5657 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5658 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5659 Set STYP_INFO for .comment.
5660 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5661 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5664 (do_linenos_for): Set lineno size in object_headers.
5665 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5666 set s_vaddr here. If string_byte_count remains 4, set it back to
5667 0, and only write strings out if there are some. Call
5668 fill_section before do_relocs_for and do_linenos_for.
5669 (obj_coff_section): Handle optional quoted second argument giving
5670 section characteristics.
5671 (obj_coff_bss): Added to handle .bss.
5672 (obj_coff_ident): Added to handle .ident (puts string in .comment
5674 (obj_coff_lcomm): Put common symbols in .bss, not .data.
5675 (fixup_mdeps): Change to segment. Call frag_wane after
5677 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5678 adjustment (already happened only for common symbols, but this is
5680 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

5692 (do_scrub_next_char): For \", return " not '.
5693 (symbol_chars): Now const.
5695 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5696 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5698 * config/obj-coff.h: Don't use #elif.
5700 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5701 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5703 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5728 using ZERO_BASED_SEGMENTS.
5729 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5730 never set segment address for SEG_E2 (.bss) and don't write out
5731 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5732 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5733 definitions, and don't merge tags with non-tags. Check for .bf
5734 rather than just checking whether the second character is b and
5735 the third character is f.
5736 (obj_coff_val): gcc can generate values which we don't handle
5737 correctly; discard information for now, since it only affects the
5738 debugging information.
5739 (tag_find_or_name): Don't insert tags in the symbol table.
5740 (yank_symbols): Don't merge labels.
5741 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5744 (obj_coff_section): Accept and ignore a trailing quoted string, as
5745 used in AT&T i386 syntax.
5746 (fixup_segment): Take segment as argument. On the i386, adjust PC
5747 relative addends by the segment vaddr.
5748 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
5749 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

5886 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
5887 could be doing emulation.
5889 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5892 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
5895 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

5921 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5923 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5924 constant will not fit in an immediate field.
5925 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
5927 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

5944 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
5945 so widening works consistently.
5947 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)

5960 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5962 * Support for i386-sysv.
5963 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5967 (fill_section): Don't set STYP_NOLOAD for .bss section.
5968 (fixup_segment): 386 uses strange common symbol format.

5987 * tc-m68k.c (get_num): make it work for all segments, not just the
5990 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
5992 * configure.in: recognize i386-*-bsd emulation.

6001 * tc-z8k.c: lots of bug fixes
6003 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6005 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6006 #elif, since it is not supported by old compilers.
6007 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6008 couple of expressions in tc-m68k.c.
6010 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6012 * read.c (cons): If NO_RELOC is defined, use it.
6014 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6016 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6018 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6019 local labels to start with a .) and set REGISTER_PREFIX to %.
6020 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6022 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6024 * messages.c: Comment changes.
6026 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

6029 * messages.c: If __STDC__ is not defined, define NO_STDARG.
6031 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
6033 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6036 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6038 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6039 sections starting from zero, rather than making them consecutive.
6040 This makes subsequent reloc calculations easier, esp if the object
6041 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6042 allocate lcomm in .data rather than in .bss. It seems that some
6043 tools can't cope with a non-zero sized bss before linkage.
6045 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6047 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6048 throughout. That enum no longer means what we thought it meant.
6050 * tc-m68k.c (md_assemble, md_parse_option): Handle new
6051 "-mno-688[58]1" options.
6053 * tc-m68k.c: Added CPU32 support.
6055 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

6061 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
6062 Change LIBDEPS dependence to LIBS.
6064 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6066 * Makefile.in (install): if $(tooldir) exists, install as in
6069 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6071 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6072 .word is < -32768 or > 32767. The -J flag causes the error to be
6073 ignored. This is to catch over-sized switches generated by gcc on
6074 systems which don't support the broken .word hack.
6075 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6076 write.c (fixup_segment): check for signed .word overflow if
6077 WARN_SIGNED_OVERFLOW_WORD.
6079 * write.c (fixup_segment): fixed missing parens in expression
6080 checking for byte or word overflow.
6082 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

6094 * tc-i386.h : new coff defines
6096 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6098 * input-scrub.c (input_scrub_push): call input_file_begin, not
6100 messages.c (as_perror): print ": " between the passed in error and
6101 the strerror, like perror does.
6103 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6105 * Makefile.in: use gas_target instead of modifying target_cpu.
6106 From Steve Chamberlain:
6107 Makefile.in: Handle m68*-*-coff*.
6108 read.c, read.h: add mult argument to s_space
6110 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6111 Motorola and MIT syntax; gas can now assemble either type of
6113 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6193 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6194 written with indirection on the last two operands, which can be
6195 either data or address registers. Added a new operand type 'r'
6196 which accepts either register type. Added '(' to notend stuff in
6197 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6540 really strange things with things like fbge,a
6542 * as.h: include bfd.h if using many sections
6543 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so

6552 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6554 * app.c: MRI compatibility - allow single quote to start a string.

6556 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6557 * expr.c: Much rewriting, to accomodate MRI syntax for
6558 expressions. Also easier to read now.
6559 * listing.c: Put back defuns
6560 * read.c: modified to accept MRI syntax, put back listing pseudo
6561 ops so that an assembler built with NO_LISTING ignores list ops
6563 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6564 machine is a SPARC or a 29K.
6565 * config/obj-aout.c: added s_sect pseudo op
6566 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6567 fill in the timestamp.
6568 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6569 anymore, define all the relocs which the tc-<x> bit will use so we
6570 can translate from them to the coff types.
6571 * config/tc-a29k.c: reloc_type isn't ane enum any more
6572 * config/tc-m68k.c: Added NO_RELOC definition.

6591 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6592 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6593 generate these sections. .align: will use NOP_OPCODE or 0
6594 for padding. This is just for being nice to the
6597 * expr.c (operand): changed to generate local label "\001L0"
6598 starting with a ^A so that it is recognized as a local label.
6600 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6602 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6603 i/o opcodes - inb, inw, outb and outw. string manipulation with
6604 att syntax - scmp, slod, smov, ssca, ssto.
6606 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6607 to just after .file .
6609 In obj_crawl_symbol_chain() where it tries to put the external
6610 symbols apart, with the condition:

6614 it was moving too many symbols out. So I switch it back to the
6616 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6618 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6619 so that we don't use the F_RELFLG which make the linker complain
6620 that somebody has stripped the relocation info.
6622 Also, the AIX ld program require that the relocation table
6623 is sorted by r_vaddr like the standard ATT assembler does.
6625 [he also changed the sizeof(struct ...)'s into the coff
6626 style FOOSZ macros. I'm not sure this is right, but I can't
6627 remember why. xoxorich.]

6631 * Makefile.in, configure.in, doc: use the doc. Build it, install
6634 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6636 * read.c: white space and comments only.
6638 * configure.in: use the new atof-ns32.c for ns32k.
6640 * write.c: comment change only.
6642 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6643 aren't yet integrated.
6645 * tc-i860.[hc]: blew off the dust. Something must still be done
6646 about conflicting relocation types.
6648 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6651 * tc-i960.c, tc-sparc.c: white space and comments only.
6653 * tc-a29k.h: delete duplicate macro definition.
6655 * new file atof-ns32k.c copied from hack's last unreleased gas.

6659 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6662 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6663 ChangeLog's prior to this are sketchy at best. I have logs.
6664 They just aren't ChangeLogs.
