55 elf_tc_make_sections stuff. It was there to support PA braindamage
56 which has been fixed, and in the case of elf_tc_make_sections is
57 redundant with elf_tc_final_processing.

92 flag rather than signedp field. Only permit extended range if
93 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
94 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
96 * config/tc-ppc.c (ppc_size): New static variable.
97 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.

99 add it if we are assembling that size.
101 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
103 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get

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

132 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
134 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
135 branch with an instruction that uses $at, in case the branch is
137 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
138 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
139 to make it pcrel_offset.
140 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
141 reloc->address; another gruesome hack to get gas reloc handling to
144 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

153 (lituse_pending): New variable. Set by anything that generates a
154 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
155 tested by code that might want to emit a LITUSE reloc.
156 (emit_unaligned_io): New function. Currently calls md_assemble,
157 but it should eventually be converted to generate the insn itself
158 and call emit_insn directly.
159 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
160 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
161 emit_bis_r): Likewise.

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

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

208 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
210 * Makefile.in (config-stamp): If `defs' is defined, emit a
211 preprocessor directive to create a macro named by this value into
212 config.new; don't explicitly go for BFD_ASSEMBLER.
213 * configure.in: Define `defs', not `BFDDEF'. Set it to
214 MANY_SEGMENTS for any obj-coffbfd target.
215 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
216 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
218 (LOCAL_LOADLIBES): Deleted.
219 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
220 * config/m88kcoff.mt (TDEFINES): Ditto.

246 bfd_set_symtab is called.
247 (dump_section_relocs): Note whether a symbol is a section symbol
249 (adjust_reloc_syms): For now, always supply an absolute symbol for
250 fixups without symbols but not yet `done'. Use section_symbol to
251 get the symbol, instead of going directly for abs_symbol.
252 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
253 reloc is not a section symbol and is not in the symbol table.
254 (set_symtab): New function, broken out from write_object_file.
255 Counts symbol table instead of relying on an earlier count.
256 (write_object_file): Call set_symtab, but do it after potentially
257 invoking the *_frob_file macros. Don't bother counting symbols.
258 Call symbol_remove, instead of expanding it in place. Moved the
259 conditionalized `object_file_size' declaration down to
260 conditionalized block where it's used. When using the absolute
261 symbol for a fixup without a symbol, set sy_used_in_reloc.
262 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
263 the correct symbol for the absolute section.
265 * subsegs.c (section_symbol): Use symbol_new instead of
266 symbol_make, since we may want it to go into the symbol table.
267 Make the new symbol have internal linkage. If
268 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
269 symbol with the newly created GAS symbol.
270 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
271 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

276 (in_signed_range): New function.
278 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
279 (sparc_ip, label "immediate"): Reject constants for pcrel
280 instructions only if the relocation type indicates a "call"
281 instruction and the offset is within range of a "jmpl %g0". If
282 it's not in range, use the absolute section symbol plus an offset.
283 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
285 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
287 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
290 * configure.in: Eliminated all targets using obj-coff but not
291 defining BFD_ASSEMBLER; I think all such targets that are
292 supported will be matched by real CPU-OS combinations earlier in
294 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
295 some comments about the dpx2 configuration, but left it disabled,
296 since it couldn't be reached before.
297 (target a29k-amd-ebmonold): Deleted.
299 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
301 * config/tc-hppa.c (pa_import): Correctly handle importing of an
302 already defined symbol.

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

341 holger@botbso.rhein-main.de.)
342 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
343 field. (Also from Holger Teutsch.) Watch for a would-be register
344 mask that spans frags.
346 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
347 this_base, not line_base. (Patch from Andreas Arens,
348 ari@obelix.av.rwth-aachen.de.)
350 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
351 look local if they're exported or undefined. Used to be done for
354 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
355 Get it from the looked-up symbol, instead of using the string from
356 the input stream, which is no longer null-terminated.
357 (LEX_PCT): New macro, defaults to 0.
358 (lex_type): Use it for `%'.
360 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
361 (vip_op): Now static, and returns void. Callers changed. Added

367 * Makefile.in (literal.o): Provide dependencies.
369 * configure.in: Set new makefile variable OPCODES_LIB.

422 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
423 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

2419 * write.c (write_relocs): For relocs that are pc_relative and
2420 pcrel_offset and not partial_inplace, adjust reloc->addend to

2476 for keeping or rejecting configurations still under development;
2477 default is to assume production environment, and reject configs
2478 still being worked on. Mark Elf configurations (except sparc and
2479 i386) as developmental. Deleted cases matching some generic names
2480 in favor of more specific names. (E.g., when we get Alpha

2497 through inclusion of tc-hppa.h. Delete all forward declarations
2498 for functions only used within tc-hppa.c, likewise for structures,
2499 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2500 conditional code in a few small places.
2502 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2503 structures, global variables, forward declarations together.

2505 conditional code -- try to group conditional code together
2506 into a few places. Make all functions and variables which
2507 are only used within tc-hppa.c static. PARAMize all functions.
2508 Add comments to functions. Delete unused functions, variables,
2509 #defines, etc. Delete unused members within structures. Delete
2510 ldil;ble hacks -- it is believed they were installed to work
2511 around old gas bugs. Avoid using mixed case for local
2512 functions, variables, and structures. Fix formatting problems
2513 not found by GNU-indent. Add FIXME notices for things which
2514 should be worked on the near future. Delete lots of old
2515 useless (1.36 PA-SOM) code.

2532 * config/tc-hppa.c: Likewise.
2534 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2535 of elf32_symbol_type.
2536 (pa_export_args): Likewise.
2537 (elf_hppa_final_processing): Likewise.

2543 * config/tc-hppa.c: (md_section_align): Align all sections to
2544 a multiple of the section alignment rather than always a
2547 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
2548 bits are zero (eg they specify no relocations), then do not even

2588 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2590 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2591 ELF, since the ELF object format does not have these type of
2592 relocations. Change the abort into as as_bad and return
2593 BFD_RELOC_NONE to silence compiler warnings.
2594 (md_assemble): Keep track of the instruction size. Allow white
2595 space between the $ and the constant for compatibility with older
2596 gases and other assemblers.
2597 (i386_operand): Skip spaces between $ and expression.

4985 avoid some redefinition complaints on some systems.
4986 (const, volatile): Don't need these conditionally defined if we
4987 use CONST and VOLATILE from ansidecl.h.
4988 (seg_name): Use CONST, not const.

4996 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

4998 to see a segment offset here.

5003 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5005 * Makefile.in: add dvi target; as-$(config).texinfo might live in

5030 dropping a space immediately following an identifier.

5032 lines; I don't think that can be done portably.
5033 * config/tc-mips.c (macro): Use $AT if target register is zero in
5034 load instruction, which it can be for a floating point load.

5057 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5059 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5060 to be on a single line.

5108 prototypes for all static functions. Moved existing minimal
5109 debugging format support info #ifndef OBJ_ECOFF blocks.

5160 * read.c (s_ignore): Don't declare is_end_of_line. It's
5161 redundant, and triggers a VMS gcc compiler bug.
5163 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5164 current segment as an argument. (Ignored in all cases but VMS.)
5165 All callers and definitions changed.

5178 (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
5179 (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
5181 (obj_elf_xstab): New routine.
5182 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
5183 argument to s_ignore. Put "#if 0" around unused code.
5184 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5185 Call elf_xstabs for .stabs and .xstabs operators.
5187 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
5189 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
5192 * configure.in: mips-bsd configuration was missing format spec.
5195 * Makefile.in (Makefile): Depends on configure.in.
5197 * config/tc-mips.c (append_insn): Don't check for alignment of
5198 frag in memory; alignment of instructions in section is a separate
5201 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

5296 for now; should be machine-dependent.
5298 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
5299 targets, forcing BFD use.

5462 md_relax_table): Use default zero initialization.
5463 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

5476 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5478 * expr.c (operand): If character other than comma or newline is a
5479 logical end-of-line character, use the newline case.
5480 From Eric Youngdale:
5481 (operand): Set X_add_number field for floating-point numbers.
5482 (operand): Treat zero byte as end-of-operand.
5484 * configure.in (per-target): Look for with_bfd_assembler option.
5485 For now, only accept "no", until the merge is done.
5487 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5488 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5489 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5490 * read.c: Finish conversion to S_* macros in the VMS only
5491 parts of the program. Add "const" modifier to hex_value.
5492 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5494 * expr.c: Add "const" modifier to hex_value.
5495 * symbols.c: Finish conversion to S_* macros in the VMS only
5496 parts of the program. Add "const" modifier to
5497 md_[long,short]_jump_size. Remove declaration of const_flag
5498 (which will be declared in obj-vms.h).
5499 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5500 Fix arguments to VMS_write_object_file.
5501 * config-gas.com: New file. Script for VMS systems to set up the
5502 configuration to build gas for VMS, and create config.status.
5503 * make-gas.com: Redone to work with new scheme.
5504 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5506 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5507 will swap bytes if needed on a big endian system. Use throughout
5509 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5510 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5511 types of malformed stabs. Change parsing algorithm so that we are
5512 more certain of having all of the information that we need on hand.
5513 * obj-vms.c (final_forward_reference): New function, used to help
5514 resolve the data types of as many struct elements as possible
5515 when some part of the struct is not fully defined by the compiler.
5516 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5518 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5519 as symbols as well in the object file. Look for external functions
5520 that start with "__vt.", and turn them into variables, since the
5521 g++ compiler is incapable of doing this.
5522 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5524 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5525 * input-scrub.c (as_where): Fix bug where as would crash if we did not

5529 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5531 * read.c (s_data): Always use "data_section", since it'll map to
5532 SEG_DATA or SEG_E1 if needed.
5533 (s_lcomm): Likewise with bss_section.
5534 (s_fill): Use memset, not bzero.
5536 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
5538 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

5558 (big_section, reg_section, pass1_section, diff_section,
5559 absent_section, text_section, data_section, bss_section): If
5560 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5561 mapping to segT enum values.
5562 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5563 if these are used or defined, if BFD_ASSEMBLER.
5564 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5565 subseg_new split into two functions.
5566 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5568 * as.h (volatile): Don't define if already defined.
5569 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5571 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5572 declare with format attribute for -Wformat checking.
5574 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5576 * app.c, config/tc-*.c: Don't include read.h, since it is already
5579 * These are based on patches from Minh Tran-le
5580 <mtranle@paris.intellicorp.com>.
5581 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5582 obj_format coffbfd and gas_target i386coff for target.
5583 (i[34]86-*-isc*): New host (uses sysv).
5584 * config/i386aix.mt: Removed (no longer used).
5585 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5587 (LDFLAGS): Added, defined as -shlib.
5588 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5589 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5590 (DOT_LABEL_PREFIX): Define.
5591 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5592 name rather than L0\001.
5593 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5595 * symbols.c, symbols.h (local_bss_counter): Removed.
5596 * write.c (write_object_file): bss no longer uses
5597 local_bss_counter. Pass correct data and bss size to
5598 VMS_write_object_file.
5599 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
5600 argument, rather than using local_bss_counter.
5601 * config/tc-m88k.c (s_bss): Don't use local_bss_counter.
5602 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
5603 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
5604 (size_section): Restored sanity check.
5605 (do_relocs_for): Base section address on s_paddr rather than
5606 computing it. Adjust a29k R_IHIHALF special case to account for
5607 section paddr (used to require paddr to be zero). If there are no
5608 reclos, set s_relptr to 0. Set relocation size in object_headers.
5609 (fill_section): Always set s_vaddr here, removing
5610 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5611 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.

5617 (do_linenos_for): Set lineno size in object_headers.
5618 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5619 set s_vaddr here. If string_byte_count remains 4, set it back to
5620 0, and only write strings out if there are some. Call
5621 fill_section before do_relocs_for and do_linenos_for.
5622 (obj_coff_section): Handle optional quoted second argument giving
5623 section characteristics.

5651 * config/obj-coff.h: Don't use #elif.
5653 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

5693 (yank_symbols): Don't merge labels.
5694 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5840 could be doing emulation.
5842 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5845 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5915 * Support for i386-sysv.
5916 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5954 * tc-z8k.c: lots of bug fixes
5956 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5958 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5959 #elif, since it is not supported by old compilers.
5960 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5961 couple of expressions in tc-m68k.c.
5963 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

5989 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5991 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5992 sections starting from zero, rather than making them consecutive.
5993 This makes subsequent reloc calculations easier, esp if the object
5994 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5995 allocate lcomm in .data rather than in .bss. It seems that some
5996 tools can't cope with a non-zero sized bss before linkage.

6019 * Makefile.in (install): if $(tooldir) exists, install as in
6022 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6024 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6025 .word is < -32768 or > 32767. The -J flag causes the error to be
6026 ignored. This is to catch over-sized switches generated by gcc on
6027 systems which don't support the broken .word hack.
6028 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6029 write.c (fixup_segment): check for signed .word overflow if
6030 WARN_SIGNED_OVERFLOW_WORD.
6032 * write.c (fixup_segment): fixed missing parens in expression
6033 checking for byte or word overflow.

6049 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6051 * input-scrub.c (input_scrub_push): call input_file_begin, not
6053 messages.c (as_perror): print ": " between the passed in error and
6054 the strerror, like perror does.
6056 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6058 * Makefile.in: use gas_target instead of modifying target_cpu.
6059 From Steve Chamberlain:
6060 Makefile.in: Handle m68*-*-coff*.

6072 (write_object_file) call fixup_mdeps
6073 (fixup_segment) set fx_subsy to 0.
6074 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6076 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6079 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6081 * Makefile.in (LIBS): Include opcode library.
6083 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6103 tc-i960.c (md_ri_to_chars): Always output bout object file in
6104 little endian byte order (used to use endianness of host).
6106 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6108 * config/tc-m68k.c (init_table): Now const. Always include 68851
6109 data, so that "bc" is available to 68040 cache instructions.
6110 Added "tt0", "tt1", and 68ec030 variants.
6111 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6112 (enum _register): Added TT0, TT1.
6113 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6114 line number correctly in "internal error" messages. Don't print
6115 architecture-mismatch message for operand errors.

6144 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6146 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6147 written with indirection on the last two operands, which can be
6148 either data or address registers. Added a new operand type 'r'
6149 which accepts either register type. Added '(' to notend stuff in
6150 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6262 characteristics have been), default to 68020. Don't need extra
6263 quotes around error string.

6267 * read.c (potable): Revert sac's incorrect change made Jul 13.

6345 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6347 * write.c (write_object_file): keep the fix_tail clean, which
6348 fixes a bug in -R where relocations were being lost.
6350 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6352 * configure.in: recognize m680x0 as having sun3 emulation mode for

6396 * write.c (write_object_file): For b.out format, round up section
6397 start addresses to match required alignment.
6399 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6401 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6402 where gcc looks for it.
6404 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6406 * Makefile.in: Changed some lines to be less confusing for some

6476 * expr.c (operand): if can't work out what sort of operand it is,
6477 then look through FLT_CHARS for a hint.
6479 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6481 * Makefile.in, configure.in: removed traces of namesubdir,

6485 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6486 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6487 copyrights to '92, changed some from Cygnus to FSF.
6489 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6491 * expr.c: If an expression is single comma, then return with
6492 SEG_ABSENT rather than an error - since the sparc front end does
6493 really strange things with things like fbge,a
6495 * as.h: include bfd.h if using many sections
6496 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6497 local labels didn't work.
6498 * listing.c (list_symbol_table): don't core dump when there's no
6500 * write.c, write.h: call fix_new with the right number of args on
6502 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6505 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6507 * app.c: MRI compatibility - allow single quote to start a string.
6508 * as.c: fix typo recently introduced.
6509 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6510 * expr.c: Much rewriting, to accomodate MRI syntax for
6511 expressions. Also easier to read now.
6512 * listing.c: Put back defuns
6513 * read.c: modified to accept MRI syntax, put back listing pseudo
6514 ops so that an assembler built with NO_LISTING ignores list ops
6516 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6517 machine is a SPARC or a 29K.
6518 * config/obj-aout.c: added s_sect pseudo op
6519 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6520 fill in the timestamp.
6521 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6522 anymore, define all the relocs which the tc-<x> bit will use so we
6523 can translate from them to the coff types.
6524 * config/tc-a29k.c: reloc_type isn't ane enum any more
6525 * config/tc-m68k.c: Added NO_RELOC definition.
6527 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6529 * Makefile.in: put header files before C source for TAGS; remove
6530 references to non-existent syscalls.h.
6532 * read.c, write.c subsegs.c: back out the .bss changes.
6534 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6536 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6540 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6542 * symbols.c (local_label_name): symbols now start with ^A.
6544 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6545 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6546 generate these sections. .align: will use NOP_OPCODE or 0
6547 for padding. This is just for being nice to the
6550 * expr.c (operand): changed to generate local label "\001L0"
6551 starting with a ^A so that it is recognized as a local label.
6553 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6555 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6556 i/o opcodes - inb, inw, outb and outw. string manipulation with
6557 att syntax - scmp, slod, smov, ssca, ssto.
6559 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6560 to just after .file .
6562 In obj_crawl_symbol_chain() where it tries to put the external
6563 symbols apart, with the condition:
6564 (!S_IS_DEFINED(symbolP) &&
6565 !S_IS_DEBUG(symbolP) &&
6566 !SF_GET_STATICS(symbolP))
6567 it was moving too many symbols out. So I switch it back to the
6569 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6571 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6572 so that we don't use the F_RELFLG which make the linker complain
6573 that somebody has stripped the relocation info.
6575 Also, the AIX ld program require that the relocation table
6576 is sorted by r_vaddr like the standard ATT assembler does.
6578 [he also changed the sizeof(struct ...)'s into the coff
6579 style FOOSZ macros. I'm not sure this is right, but I can't
6580 remember why. xoxorich.]
6582 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

6591 * configure.in: use the new atof-ns32.c for ns32k.
6593 * write.c: comment change only.
6595 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6596 aren't yet integrated.
6598 * tc-i860.[hc]: blew off the dust. Something must still be done
6599 about conflicting relocation types.
6601 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6604 * tc-i960.c, tc-sparc.c: white space and comments only.
6606 * tc-a29k.h: delete duplicate macro definition.
6608 * new file atof-ns32k.c copied from hack's last unreleased gas.
6610 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6612 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6615 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6616 ChangeLog's prior to this are sketchy at best. I have logs.
6617 They just aren't ChangeLogs.
6621 version-control: never
