39 argument, the reloc type.
40 (load_register): Pass reloc type to macro_build for 'u'.
41 (macro): Likewise. For M_LA_AB permit a difference expression
42 when generating embedded PIC code between an arbitrary symbol and
43 a symbol in the .text section.

88 elf_tc_make_sections stuff. It was there to support PA braindamage
89 which has been fixed, and in the case of elf_tc_make_sections is
90 redundant with elf_tc_final_processing.
92 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

110 don't spew remainder of input file in error message.
111 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
112 message with reloc type and try to process remainder of file.
114 * doc/Makefile.in (install-info-as, install-info-gasp): New
115 targets, now explicitly checking $(srcdir) for info files.

124 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
125 flag rather than signedp field. Only permit extended range if
126 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
127 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
129 * config/tc-ppc.c (ppc_size): New static variable.
130 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
131 (md_begin): If an instruction has a size specific flag set, only
132 add it if we are assembling that size.
134 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
136 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get

147 the type of symbol set symbols which happen to be in the absolute
148 or undefined section.
150 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
152 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
153 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
154 and -many (all architectures).

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

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

201 the value can't be resolved.
203 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
205 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
206 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

209 (mips_force_relocation): New function.
210 (md_apply_fix): Set fixP->fx_done appropriately.

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

241 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
243 * Makefile.in (config-stamp): If `defs' is defined, emit a
244 preprocessor directive to create a macro named by this value into
245 config.new; don't explicitly go for BFD_ASSEMBLER.
246 * configure.in: Define `defs', not `BFDDEF'. Set it to
247 MANY_SEGMENTS for any obj-coffbfd target.
248 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
249 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
251 (LOCAL_LOADLIBES): Deleted.
252 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
253 * config/m88kcoff.mt (TDEFINES): Ditto.
254 * config/ebmon29k.mt: Deleted.

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

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

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

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

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

454 (obj_coff_section): Declare.
455 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
456 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

458 silently compiling to do nothing.
459 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
461 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

2396 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2397 the table, require that the one without bit 0x1000000 set come
2398 first. Require further that it be case 'b' or 'P'. The a29k

2452 * write.c (write_relocs): For relocs that are pc_relative and
2453 pcrel_offset and not partial_inplace, adjust reloc->addend to

2508 * configure.in: Set bfd_gas for all sparc targets. Added facility
2509 for keeping or rejecting configurations still under development;
2510 default is to assume production environment, and reject configs
2511 still being worked on. Mark Elf configurations (except sparc and
2512 i386) as developmental. Deleted cases matching some generic names
2513 in favor of more specific names. (E.g., when we get Alpha

2530 through inclusion of tc-hppa.h. Delete all forward declarations
2531 for functions only used within tc-hppa.c, likewise for structures,
2532 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2533 conditional code in a few small places.
2535 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2536 structures, global variables, forward declarations together.
2537 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
2538 conditional code -- try to group conditional code together
2539 into a few places. Make all functions and variables which
2540 are only used within tc-hppa.c static. PARAMize all functions.
2541 Add comments to functions. Delete unused functions, variables,
2542 #defines, etc. Delete unused members within structures. Delete
2543 ldil;ble hacks -- it is believed they were installed to work
2544 around old gas bugs. Avoid using mixed case for local
2545 functions, variables, and structures. Fix formatting problems
2546 not found by GNU-indent. Add FIXME notices for things which
2547 should be worked on the near future. Delete lots of old
2548 useless (1.36 PA-SOM) code.

2565 * config/tc-hppa.c: Likewise.
2567 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2568 of elf32_symbol_type.
2569 (pa_export_args): Likewise.
2570 (elf_hppa_final_processing): Likewise.

2576 * config/tc-hppa.c: (md_section_align): Align all sections to
2577 a multiple of the section alignment rather than always a
2580 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
2581 bits are zero (eg they specify no relocations), then do not even
2582 bother adding their entries to thesymextn section.

2621 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2623 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2624 ELF, since the ELF object format does not have these type of
2625 relocations. Change the abort into as as_bad and return
2626 BFD_RELOC_NONE to silence compiler warnings.
2627 (md_assemble): Keep track of the instruction size. Allow white
2628 space between the $ and the constant for compatibility with older
2629 gases and other assemblers.
2630 (i386_operand): Skip spaces between $ and expression.
2631 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

5018 avoid some redefinition complaints on some systems.

5063 dropping a space immediately following an identifier.

5066 * config/tc-mips.c (macro): Use $AT if target register is zero in
5067 load instruction, which it can be for a floating point load.

5090 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5092 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

5141 prototypes for all static functions. Moved existing minimal
5142 debugging format support info #ifndef OBJ_ECOFF blocks.

5193 * read.c (s_ignore): Don't declare is_end_of_line. It's
5194 redundant, and triggers a VMS gcc compiler bug.

5515 (operand): Treat zero byte as end-of-operand.
5517 * configure.in (per-target): Look for with_bfd_assembler option.
5518 For now, only accept "no", until the merge is done.
5520 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5521 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5527 * expr.c: Add "const" modifier to hex_value.
5528 * symbols.c: Finish conversion to S_* macros in the VMS only
5529 parts of the program. Add "const" modifier to
5530 md_[long,short]_jump_size. Remove declaration of const_flag
5531 (which will be declared in obj-vms.h).
5532 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5533 Fix arguments to VMS_write_object_file.
5534 * config-gas.com: New file. Script for VMS systems to set up the
5535 configuration to build gas for VMS, and create config.status.

5594 mapping to segT enum values.
5595 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5596 if these are used or defined, if BFD_ASSEMBLER.
5597 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5598 subseg_new split into two functions.
5599 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5601 * as.h (volatile): Don't define if already defined.
5602 (had_errors, had_warnings): Provide prototypes for ANSI C even if

5626 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5628 * symbols.c, symbols.h (local_bss_counter): Removed.
5629 * write.c (write_object_file): bss no longer uses
5630 local_bss_counter. Pass correct data and bss size to
5631 VMS_write_object_file.
5632 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
5633 argument, rather than using local_bss_counter.

5637 (size_section): Restored sanity check.
5638 (do_relocs_for): Base section address on s_paddr rather than
5639 computing it. Adjust a29k R_IHIHALF special case to account for
5640 section paddr (used to require paddr to be zero). If there are no
5641 reclos, set s_relptr to 0. Set relocation size in object_headers.
5642 (fill_section): Always set s_vaddr here, removing
5643 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5644 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5645 Set STYP_INFO for .comment.
5646 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5647 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5649 H_{SET,GET}_* macros.
5650 (do_linenos_for): Set lineno size in object_headers.
5651 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5652 set s_vaddr here. If string_byte_count remains 4, set it back to
5653 0, and only write strings out if there are some. Call
5654 fill_section before do_relocs_for and do_linenos_for.
5655 (obj_coff_section): Handle optional quoted second argument giving
5656 section characteristics.
5657 (obj_coff_bss): Added to handle .bss.
5658 (obj_coff_ident): Added to handle .ident (puts string in .comment
5660 (obj_coff_lcomm): Put common symbols in .bss, not .data.
5661 (fixup_mdeps): Change to segment. Call frag_wane after
5663 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5664 adjustment (already happened only for common symbols, but this is
5666 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
5667 * config/tc-i386.c (s_bss): Don't use if I386COFF.

5678 (do_scrub_next_char): For \", return " not '.
5679 (symbol_chars): Now const.
5681 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5682 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5684 * config/obj-coff.h: Don't use #elif.
5686 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5687 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5689 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5713 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5714 using ZERO_BASED_SEGMENTS.
5715 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5716 never set segment address for SEG_E2 (.bss) and don't write out
5717 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5718 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5719 definitions, and don't merge tags with non-tags. Check for .bf
5720 rather than just checking whether the second character is b and
5721 the third character is f.
5722 (obj_coff_val): gcc can generate values which we don't handle
5723 correctly; discard information for now, since it only affects the
5724 debugging information.
5725 (tag_find_or_name): Don't insert tags in the symbol table.
5726 (yank_symbols): Don't merge labels.
5727 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5730 (obj_coff_section): Accept and ignore a trailing quoted string, as
5731 used in AT&T i386 syntax.
5732 (fixup_segment): Take segment as argument. On the i386, adjust PC
5733 relative addends by the segment vaddr.

5872 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
5873 could be doing emulation.
5875 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5878 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5907 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5909 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5910 constant will not fit in an immediate field.
5911 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5946 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5948 * Support for i386-sysv.
5949 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5973 * tc-m68k.c (get_num): make it work for all segments, not just the
5976 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
5978 * configure.in: recognize i386-*-bsd emulation.

5987 * tc-z8k.c: lots of bug fixes
5989 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5991 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5992 #elif, since it is not supported by old compilers.
5993 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5994 couple of expressions in tc-m68k.c.
5996 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5998 * read.c (cons): If NO_RELOC is defined, use it.
6000 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6002 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6004 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6005 local labels to start with a .) and set REGISTER_PREFIX to %.
6006 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6008 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6010 * messages.c: Comment changes.
6012 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

6015 * messages.c: If __STDC__ is not defined, define NO_STDARG.
6017 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
6019 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6022 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6024 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6025 sections starting from zero, rather than making them consecutive.
6026 This makes subsequent reloc calculations easier, esp if the object
6027 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6028 allocate lcomm in .data rather than in .bss. It seems that some
6029 tools can't cope with a non-zero sized bss before linkage.
6031 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6033 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6034 throughout. That enum no longer means what we thought it meant.
6036 * tc-m68k.c (md_assemble, md_parse_option): Handle new
6037 "-mno-688[58]1" options.
6039 * tc-m68k.c: Added CPU32 support.

6048 Change LIBDEPS dependence to LIBS.
6050 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6052 * Makefile.in (install): if $(tooldir) exists, install as in
6055 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6057 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6058 .word is < -32768 or > 32767. The -J flag causes the error to be
6059 ignored. This is to catch over-sized switches generated by gcc on
6060 systems which don't support the broken .word hack.
6061 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6062 write.c (fixup_segment): check for signed .word overflow if
6063 WARN_SIGNED_OVERFLOW_WORD.
6065 * write.c (fixup_segment): fixed missing parens in expression
6066 checking for byte or word overflow.
6068 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

6080 * tc-i386.h : new coff defines
6082 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6084 * input-scrub.c (input_scrub_push): call input_file_begin, not
6086 messages.c (as_perror): print ": " between the passed in error and
6087 the strerror, like perror does.
6089 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6091 * Makefile.in: use gas_target instead of modifying target_cpu.
6092 From Steve Chamberlain:
6093 Makefile.in: Handle m68*-*-coff*.
6094 read.c, read.h: add mult argument to s_space
6096 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6097 Motorola and MIT syntax; gas can now assemble either type of
6099 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6100 From Steve Chamberlain:
6101 m68kcoff.mt: for m68k COFF.
6102 obj-coffbfd.c: (fixup_mdeps) added
6103 (size_section) removed bad sanity check
6104 (fill_section) added rs_machine_dependent case
6105 (write_object_file) call fixup_mdeps
6106 (fixup_segment) set fx_subsy to 0.
6107 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6109 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala

6141 * config/tc-m68k.c (init_table): Now const. Always include 68851
6142 data, so that "bc" is available to 68040 cache instructions.
6143 Added "tt0", "tt1", and 68ec030 variants.
6144 (md_assemble): Complain if 68000 (only) and 68881 are specified.

6177 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6179 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6180 written with indirection on the last two operands, which can be
6181 either data or address registers. Added a new operand type 'r'
6182 which accepts either register type. Added '(' to notend stuff in
6183 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6295 characteristics have been), default to 68020. Don't need extra
6296 quotes around error string.

6432 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6434 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6435 where gcc looks for it.

6520 copyrights to '92, changed some from Cygnus to FSF.
6522 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6524 * expr.c: If an expression is single comma, then return with
6525 SEG_ABSENT rather than an error - since the sparc front end does
6526 really strange things with things like fbge,a
6528 * as.h: include bfd.h if using many sections
6529 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6530 local labels didn't work.
6531 * listing.c (list_symbol_table): don't core dump when there's no
6533 * write.c, write.h: call fix_new with the right number of args on
6535 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6538 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6540 * app.c: MRI compatibility - allow single quote to start a string.
6541 * as.c: fix typo recently introduced.
6542 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6543 * expr.c: Much rewriting, to accomodate MRI syntax for
6544 expressions. Also easier to read now.
6545 * listing.c: Put back defuns
6546 * read.c: modified to accept MRI syntax, put back listing pseudo
6547 ops so that an assembler built with NO_LISTING ignores list ops
6549 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6550 machine is a SPARC or a 29K.
6551 * config/obj-aout.c: added s_sect pseudo op
6552 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6553 fill in the timestamp.
6554 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6555 anymore, define all the relocs which the tc-<x> bit will use so we
6556 can translate from them to the coff types.
6557 * config/tc-a29k.c: reloc_type isn't ane enum any more
6558 * config/tc-m68k.c: Added NO_RELOC definition.
6560 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6562 * Makefile.in: put header files before C source for TAGS; remove
6563 references to non-existent syscalls.h.
6565 * read.c, write.c subsegs.c: back out the .bss changes.
6567 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6569 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6573 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6575 * symbols.c (local_label_name): symbols now start with ^A.
6577 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6578 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6579 generate these sections. .align: will use NOP_OPCODE or 0
6580 for padding. This is just for being nice to the
6583 * expr.c (operand): changed to generate local label "\001L0"
6584 starting with a ^A so that it is recognized as a local label.
6586 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6588 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6589 i/o opcodes - inb, inw, outb and outw. string manipulation with
6590 att syntax - scmp, slod, smov, ssca, ssto.
6592 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6593 to just after .file .
6595 In obj_crawl_symbol_chain() where it tries to put the external
6596 symbols apart, with the condition:
6597 (!S_IS_DEFINED(symbolP) &&
6598 !S_IS_DEBUG(symbolP) &&
6599 !SF_GET_STATICS(symbolP))
6600 it was moving too many symbols out. So I switch it back to the
6602 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6604 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6605 so that we don't use the F_RELFLG which make the linker complain
6606 that somebody has stripped the relocation info.
6608 Also, the AIX ld program require that the relocation table
6609 is sorted by r_vaddr like the standard ATT assembler does.
6611 [he also changed the sizeof(struct ...)'s into the coff

6624 * configure.in: use the new atof-ns32.c for ns32k.
6626 * write.c: comment change only.

6632 about conflicting relocation types.

6637 * tc-i960.c, tc-sparc.c: white space and comments only.
