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

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

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

189 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
191 (lituse_pending): New variable. Set by anything that generates a
192 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
193 tested by code that might want to emit a LITUSE reloc.
194 (emit_unaligned_io): New function. Currently calls md_assemble,
195 but it should eventually be converted to generate the insn itself
196 and call emit_insn directly.
197 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
198 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
199 emit_bis_r): Likewise.

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

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

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

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

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

345 the 'j' operand if there are no further alternatives for this
348 * config/obj-coffbfd.c (adjust_stab_section): Initialize
349 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
350 is not SEG_UNKNOWN rather than checking whether it is >= 0.
352 * config/tc-mips.c (mips_align): Take new argument, label, and use
353 it instead of global insn_label.
354 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
355 call to mips_emit_delay and pass it to mips_align.
357 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
359 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
361 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
362 argument to a .callinfo directive. Don't loop forever on errors.
364 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
365 use pre-defined registers as arguments.
367 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
369 * write.c (write_object_file): Check both S_IS_LOCAL and
370 S_IS_EXTERNAL when deciding whether to discard a symbol.
372 * config-gas.com: Scan Makefile.in, not version.c, for current
373 version number. Delete all versions of temp files when finished
374 with them. Create config.h.
376 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
377 values to reduce number of lookups with S_GET_VALUE. Skip debug

379 holger@botbso.rhein-main.de.)
380 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
381 field. (Also from Holger Teutsch.) Watch for a would-be register
382 mask that spans frags.
384 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
385 this_base, not line_base. (Patch from Andreas Arens,
386 ari@obelix.av.rwth-aachen.de.)
388 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
389 look local if they're exported or undefined. Used to be done for
392 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
393 Get it from the looked-up symbol, instead of using the string from
394 the input stream, which is no longer null-terminated.
395 (LEX_PCT): New macro, defaults to 0.
396 (lex_type): Use it for `%'.
398 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
399 (vip_op): Now static, and returns void. Callers changed. Added

459 (obj_coff_section): Declare.
460 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
461 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

2401 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2402 the table, require that the one without bit 0x1000000 set come
2403 first. Require further that it be case 'b' or 'P'. The a29k

2457 * write.c (write_relocs): For relocs that are pc_relative and
2458 pcrel_offset and not partial_inplace, adjust reloc->addend to

2514 for keeping or rejecting configurations still under development;
2515 default is to assume production environment, and reject configs
2516 still being worked on. Mark Elf configurations (except sparc and
2517 i386) as developmental. Deleted cases matching some generic names
2518 in favor of more specific names. (E.g., when we get Alpha

2535 through inclusion of tc-hppa.h. Delete all forward declarations
2536 for functions only used within tc-hppa.c, likewise for structures,
2537 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2538 conditional code in a few small places.
2540 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2541 structures, global variables, forward declarations together.

2543 conditional code -- try to group conditional code together
2544 into a few places. Make all functions and variables which
2545 are only used within tc-hppa.c static. PARAMize all functions.
2546 Add comments to functions. Delete unused functions, variables,
2547 #defines, etc. Delete unused members within structures. Delete
2548 ldil;ble hacks -- it is believed they were installed to work
2549 around old gas bugs. Avoid using mixed case for local
2550 functions, variables, and structures. Fix formatting problems
2551 not found by GNU-indent. Add FIXME notices for things which
2552 should be worked on the near future. Delete lots of old
2553 useless (1.36 PA-SOM) code.

2570 * config/tc-hppa.c: Likewise.
2572 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2573 of elf32_symbol_type.
2574 (pa_export_args): Likewise.

2581 * config/tc-hppa.c: (md_section_align): Align all sections to
2582 a multiple of the section alignment rather than always a
2585 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2626 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2628 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2629 ELF, since the ELF object format does not have these type of
2630 relocations. Change the abort into as as_bad and return
2631 BFD_RELOC_NONE to silence compiler warnings.
2632 (md_assemble): Keep track of the instruction size. Allow white
2633 space between the $ and the constant for compatibility with older
2634 gases and other assemblers.
2635 (i386_operand): Skip spaces between $ and expression.
2636 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

5023 avoid some redefinition complaints on some systems.

5034 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

5068 dropping a space immediately following an identifier.

5071 * config/tc-mips.c (macro): Use $AT if target register is zero in
5072 load instruction, which it can be for a floating point load.

5095 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5097 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

5146 prototypes for all static functions. Moved existing minimal
5147 debugging format support info #ifndef OBJ_ECOFF blocks.

5198 * read.c (s_ignore): Don't declare is_end_of_line. It's
5199 redundant, and triggers a VMS gcc compiler bug.

5520 (operand): Treat zero byte as end-of-operand.
5522 * configure.in (per-target): Look for with_bfd_assembler option.
5523 For now, only accept "no", until the merge is done.
5525 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5526 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5532 * expr.c: Add "const" modifier to hex_value.
5533 * symbols.c: Finish conversion to S_* macros in the VMS only
5534 parts of the program. Add "const" modifier to
5535 md_[long,short]_jump_size. Remove declaration of const_flag
5536 (which will be declared in obj-vms.h).
5537 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5538 Fix arguments to VMS_write_object_file.
5539 * config-gas.com: New file. Script for VMS systems to set up the

5599 mapping to segT enum values.
5600 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5601 if these are used or defined, if BFD_ASSEMBLER.
5602 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5603 subseg_new split into two functions.
5604 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5606 * as.h (volatile): Don't define if already defined.
5607 (had_errors, had_warnings): Provide prototypes for ANSI C even if

5631 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5633 * symbols.c, symbols.h (local_bss_counter): Removed.
5634 * write.c (write_object_file): bss no longer uses
5635 local_bss_counter. Pass correct data and bss size to
5636 VMS_write_object_file.
5637 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
5638 argument, rather than using local_bss_counter.

5642 (size_section): Restored sanity check.
5643 (do_relocs_for): Base section address on s_paddr rather than
5644 computing it. Adjust a29k R_IHIHALF special case to account for
5645 section paddr (used to require paddr to be zero). If there are no
5646 reclos, set s_relptr to 0. Set relocation size in object_headers.
5647 (fill_section): Always set s_vaddr here, removing
5648 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5649 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5650 Set STYP_INFO for .comment.
5651 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5652 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5654 H_{SET,GET}_* macros.
5655 (do_linenos_for): Set lineno size in object_headers.
5656 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5657 set s_vaddr here. If string_byte_count remains 4, set it back to
5658 0, and only write strings out if there are some. Call
5659 fill_section before do_relocs_for and do_linenos_for.
5660 (obj_coff_section): Handle optional quoted second argument giving
5661 section characteristics.
5662 (obj_coff_bss): Added to handle .bss.
5663 (obj_coff_ident): Added to handle .ident (puts string in .comment
5665 (obj_coff_lcomm): Put common symbols in .bss, not .data.
5666 (fixup_mdeps): Change to segment. Call frag_wane after
5668 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5669 adjustment (already happened only for common symbols, but this is
5671 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
5672 * config/tc-i386.c (s_bss): Don't use if I386COFF.

5680 Mon Dec 28 10:32:05 1992 Ken Raeburn (raeburn@cygnus.com)
5682 * app.c (app_push): Use memcpy, not bcopy.
5683 (do_scrub_next_char): For \", return " not '.
5684 (symbol_chars): Now const.
5686 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5687 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5689 * config/obj-coff.h: Don't use #elif.
5691 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5692 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5694 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5719 using ZERO_BASED_SEGMENTS.
5720 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5721 never set segment address for SEG_E2 (.bss) and don't write out
5722 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5723 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5724 definitions, and don't merge tags with non-tags. Check for .bf
5725 rather than just checking whether the second character is b and
5726 the third character is f.
5727 (obj_coff_val): gcc can generate values which we don't handle
5728 correctly; discard information for now, since it only affects the
5729 debugging information.
5730 (tag_find_or_name): Don't insert tags in the symbol table.
5731 (yank_symbols): Don't merge labels.
5732 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5735 (obj_coff_section): Accept and ignore a trailing quoted string, as
5736 used in AT&T i386 syntax.
5737 (fixup_segment): Take segment as argument. On the i386, adjust PC
5738 relative addends by the segment vaddr.

5877 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
5878 could be doing emulation.
5880 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5883 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5912 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5914 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5915 constant will not fit in an immediate field.
5916 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5951 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5953 * Support for i386-sysv.
5954 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5978 * tc-m68k.c (get_num): make it work for all segments, not just the
5981 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

5992 * tc-z8k.c: lots of bug fixes
5994 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5996 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5997 #elif, since it is not supported by old compilers.
5998 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5999 couple of expressions in tc-m68k.c.
6001 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6003 * read.c (cons): If NO_RELOC is defined, use it.
6005 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6007 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6009 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6010 local labels to start with a .) and set REGISTER_PREFIX to %.
6011 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6013 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6015 * messages.c: Comment changes.
6017 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

6020 * messages.c: If __STDC__ is not defined, define NO_STDARG.
6022 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
6024 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6027 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6029 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6030 sections starting from zero, rather than making them consecutive.
6031 This makes subsequent reloc calculations easier, esp if the object
6032 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6033 allocate lcomm in .data rather than in .bss. It seems that some
6034 tools can't cope with a non-zero sized bss before linkage.
6036 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6038 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6039 throughout. That enum no longer means what we thought it meant.
6041 * tc-m68k.c (md_assemble, md_parse_option): Handle new
6042 "-mno-688[58]1" options.
6044 * tc-m68k.c: Added CPU32 support.

6053 Change LIBDEPS dependence to LIBS.
6055 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6057 * Makefile.in (install): if $(tooldir) exists, install as in
6060 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6062 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6063 .word is < -32768 or > 32767. The -J flag causes the error to be
6064 ignored. This is to catch over-sized switches generated by gcc on
6065 systems which don't support the broken .word hack.
6066 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6067 write.c (fixup_segment): check for signed .word overflow if
6068 WARN_SIGNED_OVERFLOW_WORD.
6070 * write.c (fixup_segment): fixed missing parens in expression
6071 checking for byte or word overflow.
6073 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

6085 * tc-i386.h : new coff defines
6087 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6089 * input-scrub.c (input_scrub_push): call input_file_begin, not
6091 messages.c (as_perror): print ": " between the passed in error and
6092 the strerror, like perror does.
6094 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6096 * Makefile.in: use gas_target instead of modifying target_cpu.
6097 From Steve Chamberlain:
6098 Makefile.in: Handle m68*-*-coff*.
6099 read.c, read.h: add mult argument to s_space
6101 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6102 Motorola and MIT syntax; gas can now assemble either type of
6104 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6105 From Steve Chamberlain:
6106 m68kcoff.mt: for m68k COFF.
6107 obj-coffbfd.c: (fixup_mdeps) added
6108 (size_section) removed bad sanity check
6109 (fill_section) added rs_machine_dependent case
6110 (write_object_file) call fixup_mdeps
6111 (fixup_segment) set fx_subsy to 0.
6112 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6114 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala

6146 * config/tc-m68k.c (init_table): Now const. Always include 68851
6147 data, so that "bc" is available to 68040 cache instructions.
6148 Added "tt0", "tt1", and 68ec030 variants.
6149 (md_assemble): Complain if 68000 (only) and 68881 are specified.

6182 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6184 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6185 written with indirection on the last two operands, which can be
6186 either data or address registers. Added a new operand type 'r'
6187 which accepts either register type. Added '(' to notend stuff in
6188 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6298 processor/opcode mismatch, so reword the error message.
6299 (md_assemble): If no CPU has been set (even if FPU/PMMU
6300 characteristics have been), default to 68020. Don't need extra
6301 quotes around error string.

6383 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6385 * write.c (write_object_file): keep the fix_tail clean, which
6386 fixes a bug in -R where relocations were being lost.

6437 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6439 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6440 where gcc looks for it.

6525 copyrights to '92, changed some from Cygnus to FSF.
6527 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6529 * expr.c: If an expression is single comma, then return with
6530 SEG_ABSENT rather than an error - since the sparc front end does
6531 really strange things with things like fbge,a
6533 * as.h: include bfd.h if using many sections
6534 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6535 local labels didn't work.
6536 * listing.c (list_symbol_table): don't core dump when there's no
6538 * write.c, write.h: call fix_new with the right number of args on
6540 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6543 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6545 * app.c: MRI compatibility - allow single quote to start a string.
6546 * as.c: fix typo recently introduced.
6547 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6548 * expr.c: Much rewriting, to accomodate MRI syntax for
6549 expressions. Also easier to read now.
6550 * listing.c: Put back defuns
6551 * read.c: modified to accept MRI syntax, put back listing pseudo
6552 ops so that an assembler built with NO_LISTING ignores list ops
6554 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6555 machine is a SPARC or a 29K.
6556 * config/obj-aout.c: added s_sect pseudo op
6557 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6558 fill in the timestamp.
6559 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6560 anymore, define all the relocs which the tc-<x> bit will use so we
6561 can translate from them to the coff types.
6562 * config/tc-a29k.c: reloc_type isn't ane enum any more
6563 * config/tc-m68k.c: Added NO_RELOC definition.
6565 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6567 * Makefile.in: put header files before C source for TAGS; remove
6568 references to non-existent syscalls.h.
6570 * read.c, write.c subsegs.c: back out the .bss changes.
6572 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6574 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6578 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6580 * symbols.c (local_label_name): symbols now start with ^A.
6582 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6583 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6584 generate these sections. .align: will use NOP_OPCODE or 0
6585 for padding. This is just for being nice to the
6588 * expr.c (operand): changed to generate local label "\001L0"
6589 starting with a ^A so that it is recognized as a local label.
6591 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6593 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6594 i/o opcodes - inb, inw, outb and outw. string manipulation with
6595 att syntax - scmp, slod, smov, ssca, ssto.
6597 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6598 to just after .file .
6600 In obj_crawl_symbol_chain() where it tries to put the external
6601 symbols apart, with the condition:
6602 (!S_IS_DEFINED(symbolP) &&
6603 !S_IS_DEBUG(symbolP) &&
6604 !SF_GET_STATICS(symbolP))
6605 it was moving too many symbols out. So I switch it back to the
6607 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6609 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6610 so that we don't use the F_RELFLG which make the linker complain
6611 that somebody has stripped the relocation info.
6613 Also, the AIX ld program require that the relocation table
6614 is sorted by r_vaddr like the standard ATT assembler does.
6616 [he also changed the sizeof(struct ...)'s into the coff

6629 * configure.in: use the new atof-ns32.c for ns32k.
6631 * write.c: comment change only.

6637 about conflicting relocation types.

6642 * tc-i960.c, tc-sparc.c: white space and comments only.

6646 * new file atof-ns32k.c copied from hack's last unreleased gas.
