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

107 message with reloc type and try to process remainder of file.
109 * doc/Makefile.in (install-info-as, install-info-gasp): New
110 targets, now explicitly checking $(srcdir) for info files.

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

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

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

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

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

204 (mips_force_relocation): New function.
205 (md_apply_fix): Set fixP->fx_done appropriately.

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

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

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

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

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

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

449 (obj_coff_section): Declare.
450 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
451 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

2391 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2392 the table, require that the one without bit 0x1000000 set come
2393 first. Require further that it be case 'b' or 'P'. The a29k

2447 * write.c (write_relocs): For relocs that are pc_relative and
2448 pcrel_offset and not partial_inplace, adjust reloc->addend to

2504 for keeping or rejecting configurations still under development;
2505 default is to assume production environment, and reject configs
2506 still being worked on. Mark Elf configurations (except sparc and
2507 i386) as developmental. Deleted cases matching some generic names
2508 in favor of more specific names. (E.g., when we get Alpha

2525 through inclusion of tc-hppa.h. Delete all forward declarations
2526 for functions only used within tc-hppa.c, likewise for structures,
2527 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2528 conditional code in a few small places.
2530 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2531 structures, global variables, forward declarations together.

2533 conditional code -- try to group conditional code together
2534 into a few places. Make all functions and variables which
2535 are only used within tc-hppa.c static. PARAMize all functions.
2536 Add comments to functions. Delete unused functions, variables,
2537 #defines, etc. Delete unused members within structures. Delete
2538 ldil;ble hacks -- it is believed they were installed to work
2539 around old gas bugs. Avoid using mixed case for local
2540 functions, variables, and structures. Fix formatting problems
2541 not found by GNU-indent. Add FIXME notices for things which
2542 should be worked on the near future. Delete lots of old
2543 useless (1.36 PA-SOM) code.

2560 * config/tc-hppa.c: Likewise.
2562 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2563 of elf32_symbol_type.
2564 (pa_export_args): Likewise.
2565 (elf_hppa_final_processing): Likewise.

2571 * config/tc-hppa.c: (md_section_align): Align all sections to
2572 a multiple of the section alignment rather than always a
2575 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2616 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2618 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2619 ELF, since the ELF object format does not have these type of
2620 relocations. Change the abort into as as_bad and return
2621 BFD_RELOC_NONE to silence compiler warnings.
2622 (md_assemble): Keep track of the instruction size. Allow white
2623 space between the $ and the constant for compatibility with older
2624 gases and other assemblers.
2625 (i386_operand): Skip spaces between $ and expression.
2626 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

5013 avoid some redefinition complaints on some systems.

5061 * config/tc-mips.c (macro): Use $AT if target register is zero in
5062 load instruction, which it can be for a floating point load.

5188 * read.c (s_ignore): Don't declare is_end_of_line. It's
5189 redundant, and triggers a VMS gcc compiler bug.

5510 (operand): Treat zero byte as end-of-operand.
5512 * configure.in (per-target): Look for with_bfd_assembler option.
5513 For now, only accept "no", until the merge is done.
5515 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5516 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5525 md_[long,short]_jump_size. Remove declaration of const_flag
5526 (which will be declared in obj-vms.h).
5527 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5528 Fix arguments to VMS_write_object_file.
5529 * config-gas.com: New file. Script for VMS systems to set up the

5591 if these are used or defined, if BFD_ASSEMBLER.
5592 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5593 subseg_new split into two functions.
5594 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5596 * as.h (volatile): Don't define if already defined.

5623 * symbols.c, symbols.h (local_bss_counter): Removed.
5624 * write.c (write_object_file): bss no longer uses
5625 local_bss_counter. Pass correct data and bss size to
5626 VMS_write_object_file.
5627 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
5628 argument, rather than using local_bss_counter.

5632 (size_section): Restored sanity check.
5633 (do_relocs_for): Base section address on s_paddr rather than
5634 computing it. Adjust a29k R_IHIHALF special case to account for
5635 section paddr (used to require paddr to be zero). If there are no
5636 reclos, set s_relptr to 0. Set relocation size in object_headers.
5637 (fill_section): Always set s_vaddr here, removing
5638 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5639 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5640 Set STYP_INFO for .comment.
5641 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5642 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
5643 (crawl_symbols): Handle 8 character section name correctly. Use
5644 H_{SET,GET}_* macros.
5645 (do_linenos_for): Set lineno size in object_headers.
5646 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5647 set s_vaddr here. If string_byte_count remains 4, set it back to
5648 0, and only write strings out if there are some. Call
5649 fill_section before do_relocs_for and do_linenos_for.
5650 (obj_coff_section): Handle optional quoted second argument giving
5651 section characteristics.
5652 (obj_coff_bss): Added to handle .bss.
5653 (obj_coff_ident): Added to handle .ident (puts string in .comment
5655 (obj_coff_lcomm): Put common symbols in .bss, not .data.
5656 (fixup_mdeps): Change to segment. Call frag_wane after
5658 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5659 adjustment (already happened only for common symbols, but this is
5661 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
5662 * config/tc-i386.c (s_bss): Don't use if I386COFF.

5670 Mon Dec 28 10:32:05 1992 Ken Raeburn (raeburn@cygnus.com)
5672 * app.c (app_push): Use memcpy, not bcopy.
5673 (do_scrub_next_char): For \", return " not '.
5674 (symbol_chars): Now const.
5676 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5677 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5679 * config/obj-coff.h: Don't use #elif.
5681 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5682 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5684 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5709 using ZERO_BASED_SEGMENTS.
5710 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5711 never set segment address for SEG_E2 (.bss) and don't write out
5712 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5713 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5714 definitions, and don't merge tags with non-tags. Check for .bf
5715 rather than just checking whether the second character is b and
5716 the third character is f.
5717 (obj_coff_val): gcc can generate values which we don't handle
5718 correctly; discard information for now, since it only affects the
5719 debugging information.
5720 (tag_find_or_name): Don't insert tags in the symbol table.
5721 (yank_symbols): Don't merge labels.
5722 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5725 (obj_coff_section): Accept and ignore a trailing quoted string, as
5726 used in AT&T i386 syntax.
5727 (fixup_segment): Take segment as argument. On the i386, adjust PC
5728 relative addends by the segment vaddr.

5867 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
5868 could be doing emulation.
5870 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5873 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5902 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5904 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5905 constant will not fit in an immediate field.
5906 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5941 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5943 * Support for i386-sysv.
5944 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5948 (fill_section): Don't set STYP_NOLOAD for .bss section.
5949 (fixup_segment): 386 uses strange common symbol format.

5968 * tc-m68k.c (get_num): make it work for all segments, not just the
5971 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
5973 * configure.in: recognize i386-*-bsd emulation.

5982 * tc-z8k.c: lots of bug fixes
5984 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5986 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5987 #elif, since it is not supported by old compilers.
5988 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5989 couple of expressions in tc-m68k.c.
5991 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5993 * read.c (cons): If NO_RELOC is defined, use it.
5995 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5997 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5999 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6000 local labels to start with a .) and set REGISTER_PREFIX to %.
6001 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6003 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6005 * messages.c: Comment changes.

6010 * messages.c: If __STDC__ is not defined, define NO_STDARG.
6012 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
6014 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6017 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6019 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6020 sections starting from zero, rather than making them consecutive.
6021 This makes subsequent reloc calculations easier, esp if the object
6022 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6023 allocate lcomm in .data rather than in .bss. It seems that some
6024 tools can't cope with a non-zero sized bss before linkage.
6026 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6028 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6029 throughout. That enum no longer means what we thought it meant.

6032 "-mno-688[58]1" options.
6034 * tc-m68k.c: Added CPU32 support.

6045 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6047 * Makefile.in (install): if $(tooldir) exists, install as in
6050 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6052 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6053 .word is < -32768 or > 32767. The -J flag causes the error to be
6054 ignored. This is to catch over-sized switches generated by gcc on
6055 systems which don't support the broken .word hack.
6056 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6057 write.c (fixup_segment): check for signed .word overflow if
6058 WARN_SIGNED_OVERFLOW_WORD.
6060 * write.c (fixup_segment): fixed missing parens in expression
6061 checking for byte or word overflow.
6063 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

6075 * tc-i386.h : new coff defines
6077 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6079 * input-scrub.c (input_scrub_push): call input_file_begin, not
6081 messages.c (as_perror): print ": " between the passed in error and
6082 the strerror, like perror does.
6084 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6086 * Makefile.in: use gas_target instead of modifying target_cpu.
6087 From Steve Chamberlain:
6088 Makefile.in: Handle m68*-*-coff*.
6089 read.c, read.h: add mult argument to s_space
6091 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6092 Motorola and MIT syntax; gas can now assemble either type of
6094 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6095 From Steve Chamberlain:
6096 m68kcoff.mt: for m68k COFF.
6097 obj-coffbfd.c: (fixup_mdeps) added
6098 (size_section) removed bad sanity check
6099 (fill_section) added rs_machine_dependent case
6100 (write_object_file) call fixup_mdeps
6101 (fixup_segment) set fx_subsy to 0.
6102 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6104 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6107 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6109 * Makefile.in (LIBS): Include opcode library.

6172 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6174 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6175 written with indirection on the last two operands, which can be
6176 either data or address registers. Added a new operand type 'r'
6177 which accepts either register type. Added '(' to notend stuff in
6178 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6290 characteristics have been), default to 68020. Don't need extra
6291 quotes around error string.

6427 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6429 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6430 where gcc looks for it.

6513 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6514 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6515 copyrights to '92, changed some from Cygnus to FSF.
6517 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6519 * expr.c: If an expression is single comma, then return with
6520 SEG_ABSENT rather than an error - since the sparc front end does
6521 really strange things with things like fbge,a
6523 * as.h: include bfd.h if using many sections
6524 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6525 local labels didn't work.
6526 * listing.c (list_symbol_table): don't core dump when there's no
6528 * write.c, write.h: call fix_new with the right number of args on
6530 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6533 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6535 * app.c: MRI compatibility - allow single quote to start a string.
6536 * as.c: fix typo recently introduced.
6537 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6538 * expr.c: Much rewriting, to accomodate MRI syntax for
6539 expressions. Also easier to read now.
6540 * listing.c: Put back defuns
6541 * read.c: modified to accept MRI syntax, put back listing pseudo
6542 ops so that an assembler built with NO_LISTING ignores list ops
6544 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6545 machine is a SPARC or a 29K.
6546 * config/obj-aout.c: added s_sect pseudo op
6547 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6548 fill in the timestamp.
6549 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6550 anymore, define all the relocs which the tc-<x> bit will use so we
6551 can translate from them to the coff types.
6552 * config/tc-a29k.c: reloc_type isn't ane enum any more
6553 * config/tc-m68k.c: Added NO_RELOC definition.
6555 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6557 * Makefile.in: put header files before C source for TAGS; remove
6558 references to non-existent syscalls.h.
6560 * read.c, write.c subsegs.c: back out the .bss changes.
6562 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6564 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6568 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6570 * symbols.c (local_label_name): symbols now start with ^A.
6572 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6573 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6574 generate these sections. .align: will use NOP_OPCODE or 0
6575 for padding. This is just for being nice to the
6578 * expr.c (operand): changed to generate local label "\001L0"
6579 starting with a ^A so that it is recognized as a local label.
6581 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6583 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6584 i/o opcodes - inb, inw, outb and outw. string manipulation with
6585 att syntax - scmp, slod, smov, ssca, ssto.
6587 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6588 to just after .file .
6590 In obj_crawl_symbol_chain() where it tries to put the external
6591 symbols apart, with the condition:
6592 (!S_IS_DEFINED(symbolP) &&
6593 !S_IS_DEBUG(symbolP) &&
6594 !SF_GET_STATICS(symbolP))
6595 it was moving too many symbols out. So I switch it back to the
6597 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6599 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6600 so that we don't use the F_RELFLG which make the linker complain
6601 that somebody has stripped the relocation info.
6603 Also, the AIX ld program require that the relocation table
6604 is sorted by r_vaddr like the standard ATT assembler does.
6606 [he also changed the sizeof(struct ...)'s into the coff
6607 style FOOSZ macros. I'm not sure this is right, but I can't
6608 remember why. xoxorich.]

6621 * write.c: comment change only.
6623 * tc-m88k.[hc]: pulled in from hack's unfinished work. These

6627 about conflicting relocation types.

6632 * tc-i960.c, tc-sparc.c: white space and comments only.

6645 They just aren't ChangeLogs.
