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

121 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
122 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),

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

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

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

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

212 * Makefile.in (config-stamp): If `defs' is defined, emit a
213 preprocessor directive to create a macro named by this value into
214 config.new; don't explicitly go for BFD_ASSEMBLER.
215 * configure.in: Define `defs', not `BFDDEF'. Set it to
216 MANY_SEGMENTS for any obj-coffbfd target.
217 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
218 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
220 (LOCAL_LOADLIBES): Deleted.
221 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
222 * config/m88kcoff.mt (TDEFINES): Ditto.

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

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

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

343 holger@botbso.rhein-main.de.)
344 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
345 field. (Also from Holger Teutsch.) Watch for a would-be register
346 mask that spans frags.
348 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
349 this_base, not line_base. (Patch from Andreas Arens,
350 ari@obelix.av.rwth-aachen.de.)
352 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
353 look local if they're exported or undefined. Used to be done for
356 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
357 Get it from the looked-up symbol, instead of using the string from
358 the input stream, which is no longer null-terminated.

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

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

2421 * write.c (write_relocs): For relocs that are pc_relative and
2422 pcrel_offset and not partial_inplace, adjust reloc->addend to

2478 for keeping or rejecting configurations still under development;
2479 default is to assume production environment, and reject configs
2480 still being worked on. Mark Elf configurations (except sparc and
2481 i386) as developmental. Deleted cases matching some generic names
2482 in favor of more specific names. (E.g., when we get Alpha

2500 for functions only used within tc-hppa.c, likewise for structures,
2501 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2502 conditional code in a few small places.
2504 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2505 structures, global variables, forward declarations together.

2508 into a few places. Make all functions and variables which
2509 are only used within tc-hppa.c static. PARAMize all functions.
2510 Add comments to functions. Delete unused functions, variables,
2511 #defines, etc. Delete unused members within structures. Delete
2512 ldil;ble hacks -- it is believed they were installed to work
2513 around old gas bugs. Avoid using mixed case for local
2514 functions, variables, and structures. Fix formatting problems
2515 not found by GNU-indent. Add FIXME notices for things which
2516 should be worked on the near future. Delete lots of old
2517 useless (1.36 PA-SOM) code.

2534 * config/tc-hppa.c: Likewise.
2536 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2537 of elf32_symbol_type.
2538 (pa_export_args): Likewise.
2539 (elf_hppa_final_processing): Likewise.

2545 * config/tc-hppa.c: (md_section_align): Align all sections to
2546 a multiple of the section alignment rather than always a
2549 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2590 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2592 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2593 ELF, since the ELF object format does not have these type of
2594 relocations. Change the abort into as as_bad and return
2595 BFD_RELOC_NONE to silence compiler warnings.
2596 (md_assemble): Keep track of the instruction size. Allow white
2597 space between the $ and the constant for compatibility with older
2598 gases and other assemblers.
2599 (i386_operand): Skip spaces between $ and expression.

4987 avoid some redefinition complaints on some systems.
4988 (const, volatile): Don't need these conditionally defined if we
4989 use CONST and VOLATILE from ansidecl.h.
4990 (seg_name): Use CONST, not const.

4998 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

5005 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5007 * Makefile.in: add dvi target; as-$(config).texinfo might live in

5032 dropping a space immediately following an identifier.

5034 lines; I don't think that can be done portably.
5035 * config/tc-mips.c (macro): Use $AT if target register is zero in
5036 load instruction, which it can be for a floating point load.
5038 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5059 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5061 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5062 to be on a single line.

5110 prototypes for all static functions. Moved existing minimal
5111 debugging format support info #ifndef OBJ_ECOFF blocks.

5162 * read.c (s_ignore): Don't declare is_end_of_line. It's
5163 redundant, and triggers a VMS gcc compiler bug.
5165 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5166 current segment as an argument. (Ignored in all cases but VMS.)
5167 All callers and definitions changed.

5180 (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
5181 (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
5183 (obj_elf_xstab): New routine.
5184 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
5185 argument to s_ignore. Put "#if 0" around unused code.
5186 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5187 Call elf_xstabs for .stabs and .xstabs operators.
5189 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
5191 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
5194 * configure.in: mips-bsd configuration was missing format spec.
5197 * Makefile.in (Makefile): Depends on configure.in.
5199 * config/tc-mips.c (append_insn): Don't check for alignment of
5200 frag in memory; alignment of instructions in section is a separate
5203 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

5298 for now; should be machine-dependent.
5300 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
5301 targets, forcing BFD use.

5464 md_relax_table): Use default zero initialization.
5465 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

5478 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5480 * expr.c (operand): If character other than comma or newline is a
5481 logical end-of-line character, use the newline case.
5482 From Eric Youngdale:
5483 (operand): Set X_add_number field for floating-point numbers.
5484 (operand): Treat zero byte as end-of-operand.
5486 * configure.in (per-target): Look for with_bfd_assembler option.
5487 For now, only accept "no", until the merge is done.
5489 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5490 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5491 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5492 * read.c: Finish conversion to S_* macros in the VMS only
5493 parts of the program. Add "const" modifier to hex_value.
5494 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5496 * expr.c: Add "const" modifier to hex_value.
5497 * symbols.c: Finish conversion to S_* macros in the VMS only
5498 parts of the program. Add "const" modifier to
5499 md_[long,short]_jump_size. Remove declaration of const_flag
5500 (which will be declared in obj-vms.h).
5501 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5502 Fix arguments to VMS_write_object_file.
5503 * config-gas.com: New file. Script for VMS systems to set up the
5504 configuration to build gas for VMS, and create config.status.
5505 * make-gas.com: Redone to work with new scheme.
5506 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5508 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5509 will swap bytes if needed on a big endian system. Use throughout
5511 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5512 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5513 types of malformed stabs. Change parsing algorithm so that we are
5514 more certain of having all of the information that we need on hand.
5515 * obj-vms.c (final_forward_reference): New function, used to help
5516 resolve the data types of as many struct elements as possible
5517 when some part of the struct is not fully defined by the compiler.
5518 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5520 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5521 as symbols as well in the object file. Look for external functions
5522 that start with "__vt.", and turn them into variables, since the
5523 g++ compiler is incapable of doing this.
5524 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5526 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5527 * input-scrub.c (as_where): Fix bug where as would crash if we did not

5531 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5533 * read.c (s_data): Always use "data_section", since it'll map to
5534 SEG_DATA or SEG_E1 if needed.
5535 (s_lcomm): Likewise with bss_section.
5536 (s_fill): Use memset, not bzero.
5538 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
5540 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

5560 (big_section, reg_section, pass1_section, diff_section,
5561 absent_section, text_section, data_section, bss_section): If
5562 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5563 mapping to segT enum values.
5564 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5565 if these are used or defined, if BFD_ASSEMBLER.
5566 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5567 subseg_new split into two functions.
5568 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5570 * as.h (volatile): Don't define if already defined.
5571 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5573 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5574 declare with format attribute for -Wformat checking.
5576 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5578 * app.c, config/tc-*.c: Don't include read.h, since it is already
5581 * These are based on patches from Minh Tran-le
5582 <mtranle@paris.intellicorp.com>.
5583 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5584 obj_format coffbfd and gas_target i386coff for target.
5585 (i[34]86-*-isc*): New host (uses sysv).
5586 * config/i386aix.mt: Removed (no longer used).
5587 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5589 (LDFLAGS): Added, defined as -shlib.
5590 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5591 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5592 (DOT_LABEL_PREFIX): Define.
5593 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5594 name rather than L0\001.
5595 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5597 * symbols.c, symbols.h (local_bss_counter): Removed.
5598 * write.c (write_object_file): bss no longer uses
5599 local_bss_counter. Pass correct data and bss size to
5600 VMS_write_object_file.
5601 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
5602 argument, rather than using local_bss_counter.
5603 * config/tc-m88k.c (s_bss): Don't use local_bss_counter.
5604 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
5605 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
5606 (size_section): Restored sanity check.
5607 (do_relocs_for): Base section address on s_paddr rather than
5608 computing it. Adjust a29k R_IHIHALF special case to account for
5609 section paddr (used to require paddr to be zero). If there are no
5610 reclos, set s_relptr to 0. Set relocation size in object_headers.
5611 (fill_section): Always set s_vaddr here, removing
5612 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5613 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.

5620 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5621 set s_vaddr here. If string_byte_count remains 4, set it back to
5622 0, and only write strings out if there are some. Call
5623 fill_section before do_relocs_for and do_linenos_for.
5624 (obj_coff_section): Handle optional quoted second argument giving
5625 section characteristics.

5653 * config/obj-coff.h: Don't use #elif.
5655 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

5695 (yank_symbols): Don't merge labels.
5696 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5842 could be doing emulation.
5844 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5847 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5958 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5960 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5961 #elif, since it is not supported by old compilers.
5962 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5963 couple of expressions in tc-m68k.c.
5965 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

5991 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5993 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5994 sections starting from zero, rather than making them consecutive.
5995 This makes subsequent reloc calculations easier, esp if the object
5996 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5997 allocate lcomm in .data rather than in .bss. It seems that some
5998 tools can't cope with a non-zero sized bss before linkage.

6021 * Makefile.in (install): if $(tooldir) exists, install as in
6024 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6026 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6027 .word is < -32768 or > 32767. The -J flag causes the error to be
6028 ignored. This is to catch over-sized switches generated by gcc on
6029 systems which don't support the broken .word hack.
6030 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6031 write.c (fixup_segment): check for signed .word overflow if
6032 WARN_SIGNED_OVERFLOW_WORD.

6051 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6053 * input-scrub.c (input_scrub_push): call input_file_begin, not
6055 messages.c (as_perror): print ": " between the passed in error and
6056 the strerror, like perror does.
6058 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

6074 (write_object_file) call fixup_mdeps
6075 (fixup_segment) set fx_subsy to 0.
6076 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6078 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6081 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6083 * Makefile.in (LIBS): Include opcode library.

6105 tc-i960.c (md_ri_to_chars): Always output bout object file in
6106 little endian byte order (used to use endianness of host).
6108 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6110 * config/tc-m68k.c (init_table): Now const. Always include 68851
6111 data, so that "bc" is available to 68040 cache instructions.
6112 Added "tt0", "tt1", and 68ec030 variants.
6113 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6114 (enum _register): Added TT0, TT1.
6115 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6116 line number correctly in "internal error" messages. Don't print
6117 architecture-mismatch message for operand errors.

6120 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6121 than install_operand.

6146 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6148 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6149 written with indirection on the last two operands, which can be
6150 either data or address registers. Added a new operand type 'r'
6151 which accepts either register type. Added '(' to notend stuff in
6152 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6264 characteristics have been), default to 68020. Don't need extra
6265 quotes around error string.

6269 * read.c (potable): Revert sac's incorrect change made Jul 13.

6347 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6349 * write.c (write_object_file): keep the fix_tail clean, which
6350 fixes a bug in -R where relocations were being lost.
6352 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6354 * configure.in: recognize m680x0 as having sun3 emulation mode for

6398 * write.c (write_object_file): For b.out format, round up section
6399 start addresses to match required alignment.
6401 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6403 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6404 where gcc looks for it.
6406 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6408 * Makefile.in: Changed some lines to be less confusing for some

6478 * expr.c (operand): if can't work out what sort of operand it is,
6479 then look through FLT_CHARS for a hint.
6481 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6483 * Makefile.in, configure.in: removed traces of namesubdir,

6485 copyrights to '92, changed some from Cygnus to FSF.
6487 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6488 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6489 copyrights to '92, changed some from Cygnus to FSF.
6491 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6493 * expr.c: If an expression is single comma, then return with
6494 SEG_ABSENT rather than an error - since the sparc front end does
6495 really strange things with things like fbge,a
6497 * as.h: include bfd.h if using many sections
6498 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6499 local labels didn't work.
6500 * listing.c (list_symbol_table): don't core dump when there's no
6502 * write.c, write.h: call fix_new with the right number of args on
6504 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6507 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6509 * app.c: MRI compatibility - allow single quote to start a string.
6510 * as.c: fix typo recently introduced.
6511 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6512 * expr.c: Much rewriting, to accomodate MRI syntax for
6513 expressions. Also easier to read now.
6514 * listing.c: Put back defuns
6515 * read.c: modified to accept MRI syntax, put back listing pseudo
6516 ops so that an assembler built with NO_LISTING ignores list ops
6518 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6519 machine is a SPARC or a 29K.
6520 * config/obj-aout.c: added s_sect pseudo op
6521 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6522 fill in the timestamp.
6523 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6524 anymore, define all the relocs which the tc-<x> bit will use so we
6525 can translate from them to the coff types.
6526 * config/tc-a29k.c: reloc_type isn't ane enum any more
6527 * config/tc-m68k.c: Added NO_RELOC definition.
6529 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6531 * Makefile.in: put header files before C source for TAGS; remove
6532 references to non-existent syscalls.h.
6534 * read.c, write.c subsegs.c: back out the .bss changes.
6536 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6538 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6542 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6544 * symbols.c (local_label_name): symbols now start with ^A.
6546 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6547 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6548 generate these sections. .align: will use NOP_OPCODE or 0
6549 for padding. This is just for being nice to the
6552 * expr.c (operand): changed to generate local label "\001L0"
6553 starting with a ^A so that it is recognized as a local label.
6555 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6557 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6558 i/o opcodes - inb, inw, outb and outw. string manipulation with
6559 att syntax - scmp, slod, smov, ssca, ssto.
6561 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6562 to just after .file .
6564 In obj_crawl_symbol_chain() where it tries to put the external
6565 symbols apart, with the condition:
6566 (!S_IS_DEFINED(symbolP) &&
6567 !S_IS_DEBUG(symbolP) &&
6568 !SF_GET_STATICS(symbolP))
6569 it was moving too many symbols out. So I switch it back to the
6571 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6573 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6574 so that we don't use the F_RELFLG which make the linker complain
6575 that somebody has stripped the relocation info.
6577 Also, the AIX ld program require that the relocation table
6578 is sorted by r_vaddr like the standard ATT assembler does.
6580 [he also changed the sizeof(struct ...)'s into the coff
6581 style FOOSZ macros. I'm not sure this is right, but I can't
6582 remember why. xoxorich.]
6584 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

6591 * read.c: white space and comments only.
6593 * configure.in: use the new atof-ns32.c for ns32k.
6595 * write.c: comment change only.
6597 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6598 aren't yet integrated.
6600 * tc-i860.[hc]: blew off the dust. Something must still be done
6601 about conflicting relocation types.
6603 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6606 * tc-i960.c, tc-sparc.c: white space and comments only.
6608 * tc-a29k.h: delete duplicate macro definition.
6610 * new file atof-ns32k.c copied from hack's last unreleased gas.
6612 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6614 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6617 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6618 ChangeLog's prior to this are sketchy at best. I have logs.
6619 They just aren't ChangeLogs.
6623 version-control: never
