41 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
42 branch with an instruction that uses $at, in case the branch is
44 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
45 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
46 to make it pcrel_offset.
47 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
48 reloc->address; another gruesome hack to get gas reloc handling to

53 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
56 (emit_insn): New function.
57 (md_assemble): Call it.
58 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
60 (lituse_pending): New variable. Set by anything that generates a
61 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
62 tested by code that might want to emit a LITUSE reloc.
63 (emit_unaligned_io): New function. Currently calls md_assemble,
64 but it should eventually be converted to generate the insn itself
65 and call emit_insn directly.
66 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
67 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
68 emit_bis_r): Likewise.

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

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

115 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
117 * Makefile.in (config-stamp): If `defs' is defined, emit a
118 preprocessor directive to create a macro named by this value into
119 config.new; don't explicitly go for BFD_ASSEMBLER.
120 * configure.in: Define `defs', not `BFDDEF'. Set it to
121 MANY_SEGMENTS for any obj-coffbfd target.
122 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
123 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
125 (LOCAL_LOADLIBES): Deleted.
126 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
127 * config/m88kcoff.mt (TDEFINES): Ditto.

153 bfd_set_symtab is called.
154 (dump_section_relocs): Note whether a symbol is a section symbol
156 (adjust_reloc_syms): For now, always supply an absolute symbol for
157 fixups without symbols but not yet `done'. Use section_symbol to
158 get the symbol, instead of going directly for abs_symbol.
159 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
160 reloc is not a section symbol and is not in the symbol table.
161 (set_symtab): New function, broken out from write_object_file.
162 Counts symbol table instead of relying on an earlier count.
163 (write_object_file): Call set_symtab, but do it after potentially
164 invoking the *_frob_file macros. Don't bother counting symbols.
165 Call symbol_remove, instead of expanding it in place. Moved the
166 conditionalized `object_file_size' declaration down to
167 conditionalized block where it's used. When using the absolute
168 symbol for a fixup without a symbol, set sy_used_in_reloc.
169 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
170 the correct symbol for the absolute section.
172 * subsegs.c (section_symbol): Use symbol_new instead of
173 symbol_make, since we may want it to go into the symbol table.
174 Make the new symbol have internal linkage. If
175 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
176 symbol with the newly created GAS symbol.
177 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
178 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

185 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
186 (sparc_ip, label "immediate"): Reject constants for pcrel
187 instructions only if the relocation type indicates a "call"
188 instruction and the offset is within range of a "jmpl %g0". If
189 it's not in range, use the absolute section symbol plus an offset.
190 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
192 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
194 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
197 * configure.in: Eliminated all targets using obj-coff but not
198 defining BFD_ASSEMBLER; I think all such targets that are
199 supported will be matched by real CPU-OS combinations earlier in
201 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
202 some comments about the dpx2 configuration, but left it disabled,
203 since it couldn't be reached before.
204 (target a29k-amd-ebmonold): Deleted.
206 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

214 the 'j' operand if there are no further alternatives for this
217 * config/obj-coffbfd.c (adjust_stab_section): Initialize
218 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
219 is not SEG_UNKNOWN rather than checking whether it is >= 0.
221 * config/tc-mips.c (mips_align): Take new argument, label, and use
222 it instead of global insn_label.
223 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
224 call to mips_emit_delay and pass it to mips_align.
226 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
228 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
230 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
231 argument to a .callinfo directive. Don't loop forever on errors.
233 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
234 use pre-defined registers as arguments.
236 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
238 * write.c (write_object_file): Check both S_IS_LOCAL and
239 S_IS_EXTERNAL when deciding whether to discard a symbol.
241 * config-gas.com: Scan Makefile.in, not version.c, for current
242 version number. Delete all versions of temp files when finished
243 with them. Create config.h.
245 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
246 values to reduce number of lookups with S_GET_VALUE. Skip debug

248 holger@botbso.rhein-main.de.)
249 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
250 field. (Also from Holger Teutsch.) Watch for a would-be register
251 mask that spans frags.
253 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
254 this_base, not line_base. (Patch from Andreas Arens,
255 ari@obelix.av.rwth-aachen.de.)
257 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
258 look local if they're exported or undefined. Used to be done for
261 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

265 (lex_type): Use it for `%'.
267 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2377 * config/tc-m68k.h: Don't define REGISTER_PREFIX or
2378 OPTIONAL_REGISTER_PREFIX if either is already defined.
2380 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
2382 * configure.in: Set bfd_gas for all sparc targets. Added facility
2383 for keeping or rejecting configurations still under development;
2384 default is to assume production environment, and reject configs
2385 still being worked on. Mark Elf configurations (except sparc and
2386 i386) as developmental. Deleted cases matching some generic names
2387 in favor of more specific names. (E.g., when we get Alpha
2388 support, we'll still only support VMS for Vax.)
2390 * config/tc-sparc.h (md_end): New macro.
2391 * config/tc-sparc.c (md_end): Function deleted.
2392 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

2402 against placing additional object-file dependent code here. Warn
2403 against contaminating all of GAS with the internals of tc-hppa.c
2404 through inclusion of tc-hppa.h. Delete all forward declarations
2405 for functions only used within tc-hppa.c, likewise for structures,
2406 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2407 conditional code in a few small places.
2409 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2410 structures, global variables, forward declarations together.
2411 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
2412 conditional code -- try to group conditional code together
2413 into a few places. Make all functions and variables which
2414 are only used within tc-hppa.c static. PARAMize all functions.
2415 Add comments to functions. Delete unused functions, variables,
2416 #defines, etc. Delete unused members within structures. Delete
2417 ldil;ble hacks -- it is believed they were installed to work
2418 around old gas bugs. Avoid using mixed case for local
2419 functions, variables, and structures. Fix formatting problems
2420 not found by GNU-indent. Add FIXME notices for things which
2421 should be worked on the near future. Delete lots of old
2422 useless (1.36 PA-SOM) code.

2434 which do not involve function symbols.
2436 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
2437 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
2439 * config/tc-hppa.c: Likewise.
2441 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2442 of elf32_symbol_type.
2443 (pa_export_args): Likewise.
2444 (elf_hppa_final_processing): Likewise.
2445 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed
2447 (hppa_tc_make_sections): Do not declare elf_get_symtab_map any
2450 * config/tc-hppa.c: (md_section_align): Align all sections to
2451 a multiple of the section alignment rather than always a
2454 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
2455 bits are zero (eg they specify no relocations), then do not even
2456 bother adding their entries to thesymextn section.

2493 instead add a second loop over special_chars. Set alignment
2494 of text, data and bss sections to 4.
2495 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2497 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2498 ELF, since the ELF object format does not have these type of
2499 relocations. Change the abort into as as_bad and return
2500 BFD_RELOC_NONE to silence compiler warnings.
2501 (md_assemble): Keep track of the instruction size. Allow white
2502 space between the $ and the constant for compatibility with older
2503 gases and other assemblers.
2504 (i386_operand): Skip spaces between $ and expression.

4778 than ECOFF line number information.
4779 (obj_ecoff_stab): Accept non-zero values for stabs line number.

4781 to small, undefined and/or readonly sections if appropriate.
4782 Don't output symbol names containing \001 characters.
4783 (ecoff_frob_file): Make sure at least one fdr is output.

4840 dependencies are read, not when they are used).
4842 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4843 a29k .bss section; the mondfe program doesn't like it.

4864 source directory, if that's not the current directory.
4866 * configure.in (per-host): Accept MIPS host with BSD version

4892 avoid some redefinition complaints on some systems.
4893 (const, volatile): Don't need these conditionally defined if we
4894 use CONST and VOLATILE from ansidecl.h.
4895 (seg_name): Use CONST, not const.
4897 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4899 * config/tc-mips.c: Reindented to GNU standards.

4903 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4904 (fixup_segment): Add a29k special case; the linker is not prepared
4905 to see a segment offset here.
4907 * app.c (do_scrub_next_char): Added new state, 10, modifying state
4908 9 to only keep a space in between identifier characters.
4910 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4912 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4913 srcdir, might be in objdir.
4915 * doc/Makefile.in: dvi depends on as.dvi

4928 bignums, but don't emit error message.
4930 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
4932 * Makefile.in (targ-cpu.o): Depend on config.h.
4934 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4936 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4937 dropping a space immediately following an identifier.
4938 * expr.c, write.c: Rewrote assert expressions to not use multiple
4939 lines; I don't think that can be done portably.
4940 * config/tc-mips.c (macro): Use $AT if target register is zero in
4941 load instruction, which it can be for a floating point load.
4943 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
4945 * write.c (write_contents): Compute the relocs before writing out

4957 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
4960 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

4964 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4966 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4967 to be on a single line.
4969 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

5014 * config/tc-mips.c: Rearranged for ECOFF support. Added
5015 prototypes for all static functions. Moved existing minimal
5016 debugging format support info #ifndef OBJ_ECOFF blocks.

5065 * make-gas.com: Find obstack.obj if it's not in the current
5067 * read.c (s_ignore): Don't declare is_end_of_line. It's
5068 redundant, and triggers a VMS gcc compiler bug.
5070 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5071 current segment as an argument. (Ignored in all cases but VMS.)
5072 All callers and definitions changed.

5090 argument to s_ignore. Put "#if 0" around unused code.
5091 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5092 Call elf_xstabs for .stabs and .xstabs operators.

5369 md_relax_table): Use default zero initialization.
5370 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5371 latter, instead of selecting with preprocessor conditionals.
5373 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5375 * configure.in: recognise all sparclite variants
5377 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

5385 * expr.c (operand): If character other than comma or newline is a
5386 logical end-of-line character, use the newline case.
5387 From Eric Youngdale:
5388 (operand): Set X_add_number field for floating-point numbers.
5389 (operand): Treat zero byte as end-of-operand.
5391 * configure.in (per-target): Look for with_bfd_assembler option.
5392 For now, only accept "no", until the merge is done.
5394 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5395 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5397 * read.c: Finish conversion to S_* macros in the VMS only
5398 parts of the program. Add "const" modifier to hex_value.
5399 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5401 * expr.c: Add "const" modifier to hex_value.
5402 * symbols.c: Finish conversion to S_* macros in the VMS only
5403 parts of the program. Add "const" modifier to
5404 md_[long,short]_jump_size. Remove declaration of const_flag
5405 (which will be declared in obj-vms.h).
5406 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5407 Fix arguments to VMS_write_object_file.
5408 * config-gas.com: New file. Script for VMS systems to set up the
5409 configuration to build gas for VMS, and create config.status.
5410 * make-gas.com: Redone to work with new scheme.
5411 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5413 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5414 will swap bytes if needed on a big endian system. Use throughout
5416 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5417 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5418 types of malformed stabs. Change parsing algorithm so that we are
5419 more certain of having all of the information that we need on hand.
5420 * obj-vms.c (final_forward_reference): New function, used to help
5421 resolve the data types of as many struct elements as possible
5422 when some part of the struct is not fully defined by the compiler.

5425 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5426 as symbols as well in the object file. Look for external functions
5427 that start with "__vt.", and turn them into variables, since the
5428 g++ compiler is incapable of doing this.
5429 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5431 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5432 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5433 have the name of the source file yet.
5434 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5436 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5438 * read.c (s_data): Always use "data_section", since it'll map to
5439 SEG_DATA or SEG_E1 if needed.
5440 (s_lcomm): Likewise with bss_section.
5441 (s_fill): Use memset, not bzero.
5443 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5464 (section_alignment): Declare only if not BFD_ASSEMBLER.
5465 (big_section, reg_section, pass1_section, diff_section,
5466 absent_section, text_section, data_section, bss_section): If
5467 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5468 mapping to segT enum values.
5469 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5470 if these are used or defined, if BFD_ASSEMBLER.
5471 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5472 subseg_new split into two functions.
5473 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5475 * as.h (volatile): Don't define if already defined.
5476 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5478 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5479 declare with format attribute for -Wformat checking.
5481 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5483 * app.c, config/tc-*.c: Don't include read.h, since it is already
5486 * These are based on patches from Minh Tran-le
5487 <mtranle@paris.intellicorp.com>.
5488 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5489 obj_format coffbfd and gas_target i386coff for target.
5490 (i[34]86-*-isc*): New host (uses sysv).
5491 * config/i386aix.mt: Removed (no longer used).
5492 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5494 (LDFLAGS): Added, defined as -shlib.
5495 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5496 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5497 (DOT_LABEL_PREFIX): Define.
5498 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5499 name rather than L0\001.
5500 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5502 * symbols.c, symbols.h (local_bss_counter): Removed.
5503 * write.c (write_object_file): bss no longer uses

5511 (size_section): Restored sanity check.
5512 (do_relocs_for): Base section address on s_paddr rather than
5513 computing it. Adjust a29k R_IHIHALF special case to account for
5514 section paddr (used to require paddr to be zero). If there are no
5515 reclos, set s_relptr to 0. Set relocation size in object_headers.
5516 (fill_section): Always set s_vaddr here, removing
5517 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5518 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5519 Set STYP_INFO for .comment.
5520 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5521 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5523 H_{SET,GET}_* macros.
5524 (do_linenos_for): Set lineno size in object_headers.
5525 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5526 set s_vaddr here. If string_byte_count remains 4, set it back to
5527 0, and only write strings out if there are some. Call
5528 fill_section before do_relocs_for and do_linenos_for.
5529 (obj_coff_section): Handle optional quoted second argument giving
5530 section characteristics.
5531 (obj_coff_bss): Added to handle .bss.
5532 (obj_coff_ident): Added to handle .ident (puts string in .comment

5552 (do_scrub_next_char): For \", return " not '.
5553 (symbol_chars): Now const.
5555 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5556 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5558 * config/obj-coff.h: Don't use #elif.
5560 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5561 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5563 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5565 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5575 Sun Dec 13 00:04:38 1992 Ian Lance Taylor (ian@cygnus.com)
5577 * read.c (read_a_source_file): avoid calling xmalloc (0).
5579 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
5581 * listing.c: Call xmalloc, not malloc; don't declare malloc.
5583 * Changes to support SCO 3.2v4:
5584 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
5585 SEG_BSS, fill with NOP_OPCODE.
5586 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5587 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5588 using ZERO_BASED_SEGMENTS.
5589 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5590 never set segment address for SEG_E2 (.bss) and don't write out
5591 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5592 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5593 definitions, and don't merge tags with non-tags. Check for .bf
5594 rather than just checking whether the second character is b and
5595 the third character is f.
5596 (obj_coff_val): gcc can generate values which we don't handle
5597 correctly; discard information for now, since it only affects the
5598 debugging information.
5599 (tag_find_or_name): Don't insert tags in the symbol table.
5600 (yank_symbols): Don't merge labels.
5601 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5604 (obj_coff_section): Accept and ignore a trailing quoted string, as
5605 used in AT&T i386 syntax.
5606 (fixup_segment): Take segment as argument. On the i386, adjust PC
5607 relative addends by the segment vaddr.
5608 * tc-i386.h: Define SUB_SEGMENT_ALIGN.

5747 could be doing emulation.
5749 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5752 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5781 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5783 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5784 constant will not fit in an immediate field.
5785 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5820 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5822 * Support for i386-sysv.
5823 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5863 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5865 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5866 #elif, since it is not supported by old compilers.
5867 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5868 couple of expressions in tc-m68k.c.
5870 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5872 * read.c (cons): If NO_RELOC is defined, use it.
5874 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5876 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5878 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5879 local labels to start with a .) and set REGISTER_PREFIX to %.
5880 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5882 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5896 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5898 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5899 sections starting from zero, rather than making them consecutive.
5900 This makes subsequent reloc calculations easier, esp if the object
5901 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5902 allocate lcomm in .data rather than in .bss. It seems that some
5903 tools can't cope with a non-zero sized bss before linkage.
5905 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5907 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5926 * Makefile.in (install): if $(tooldir) exists, install as in
5929 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5931 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5932 .word is < -32768 or > 32767. The -J flag causes the error to be
5933 ignored. This is to catch over-sized switches generated by gcc on
5934 systems which don't support the broken .word hack.
5935 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5936 write.c (fixup_segment): check for signed .word overflow if
5937 WARN_SIGNED_OVERFLOW_WORD.
5939 * write.c (fixup_segment): fixed missing parens in expression
5940 checking for byte or word overflow.
5942 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

5956 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5958 * input-scrub.c (input_scrub_push): call input_file_begin, not
5960 messages.c (as_perror): print ": " between the passed in error and
5961 the strerror, like perror does.

5966 From Steve Chamberlain:
5967 Makefile.in: Handle m68*-*-coff*.
5968 read.c, read.h: add mult argument to s_space
5970 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5971 Motorola and MIT syntax; gas can now assemble either type of

5980 (fixup_segment) set fx_subsy to 0.
5981 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5983 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5986 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5988 * Makefile.in (LIBS): Include opcode library.
5990 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6010 tc-i960.c (md_ri_to_chars): Always output bout object file in
6011 little endian byte order (used to use endianness of host).
6013 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6015 * config/tc-m68k.c (init_table): Now const. Always include 68851
6016 data, so that "bc" is available to 68040 cache instructions.
6017 Added "tt0", "tt1", and 68ec030 variants.
6018 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6019 (enum _register): Added TT0, TT1.
6020 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6021 line number correctly in "internal error" messages. Don't print
6022 architecture-mismatch message for operand errors.
6024 From Colin Smith (colin@wrs.com):
6025 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6026 than install_operand.

6030 * listing.c (buffer_line): rewind to the start of include
6031 files, they might be included twice.
6033 * z8k.c, z8k.h, z8k.mt: z8000 support stuff

6040 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6042 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6043 so that we can assemble hand-written libgcc code.
6045 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6047 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6048 has already been formatted (but may still contain %-characters).
6051 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6053 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6054 written with indirection on the last two operands, which can be
6055 either data or address registers. Added a new operand type 'r'
6056 which accepts either register type. Added '(' to notend stuff in
6057 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6059 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
6061 * as.h (enum _relax_state): Start off at one, not zero, to better

6072 defined, call it. Change segments before calling fixup_segment.
6073 (relax_align): If linkrelax, provide extra padding.
6075 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6076 their not having symbols associated.
6078 * tc-i960.c (norelax, instrument_branches): Default initializer is
6080 (linkrelax): Delete variable definition.
6081 (mem_fmt): Call fix_new with NO_RELOC.

6104 being used with args swapped, causing occasional lossage when
6105 refilling buffers after an include file.
6107 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
6109 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6110 version. Discard bogus DONTDEF version.
6111 (as_warn, as_bad, as_fatal): Likewise.
6113 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
6115 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the

6168 (md_assemble): If no CPU has been set (even if FPU/PMMU
6169 characteristics have been), default to 68020. Don't need extra
6170 quotes around error string.

6252 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6254 * write.c (write_object_file): keep the fix_tail clean, which
6255 fixes a bug in -R where relocations were being lost.
6257 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6259 * configure.in: recognize m680x0 as having sun3 emulation mode for

6304 start addresses to match required alignment.
6306 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6308 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6309 where gcc looks for it.
6311 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6313 * Makefile.in: Changed some lines to be less confusing for some

6379 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6381 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6383 * expr.c (operand): if can't work out what sort of operand it is,
6384 then look through FLT_CHARS for a hint.
6386 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6388 * Makefile.in, configure.in: removed traces of namesubdir,
6389 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6390 copyrights to '92, changed some from Cygnus to FSF.
6392 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6393 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6394 copyrights to '92, changed some from Cygnus to FSF.
6396 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6398 * expr.c: If an expression is single comma, then return with
6399 SEG_ABSENT rather than an error - since the sparc front end does
6400 really strange things with things like fbge,a
6402 * as.h: include bfd.h if using many sections
6403 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6404 local labels didn't work.
6405 * listing.c (list_symbol_table): don't core dump when there's no
6407 * write.c, write.h: call fix_new with the right number of args on
6409 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6412 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6414 * app.c: MRI compatibility - allow single quote to start a string.
6415 * as.c: fix typo recently introduced.
6416 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6417 * expr.c: Much rewriting, to accomodate MRI syntax for
6418 expressions. Also easier to read now.
6419 * listing.c: Put back defuns
6420 * read.c: modified to accept MRI syntax, put back listing pseudo
6421 ops so that an assembler built with NO_LISTING ignores list ops
6423 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6424 machine is a SPARC or a 29K.
6425 * config/obj-aout.c: added s_sect pseudo op
6426 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6427 fill in the timestamp.
6428 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6429 anymore, define all the relocs which the tc-<x> bit will use so we
6430 can translate from them to the coff types.
6431 * config/tc-a29k.c: reloc_type isn't ane enum any more
6432 * config/tc-m68k.c: Added NO_RELOC definition.
6434 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6436 * Makefile.in: put header files before C source for TAGS; remove
6437 references to non-existent syscalls.h.
6439 * read.c, write.c subsegs.c: back out the .bss changes.
6441 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6443 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6447 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6449 * symbols.c (local_label_name): symbols now start with ^A.
6451 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6452 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6453 generate these sections. .align: will use NOP_OPCODE or 0
6454 for padding. This is just for being nice to the
6457 * expr.c (operand): changed to generate local label "\001L0"
6458 starting with a ^A so that it is recognized as a local label.
6460 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6462 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6463 i/o opcodes - inb, inw, outb and outw. string manipulation with
6464 att syntax - scmp, slod, smov, ssca, ssto.
6466 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6467 to just after .file .
6469 In obj_crawl_symbol_chain() where it tries to put the external
6470 symbols apart, with the condition:
6471 (!S_IS_DEFINED(symbolP) &&
6472 !S_IS_DEBUG(symbolP) &&
6473 !SF_GET_STATICS(symbolP))
6474 it was moving too many symbols out. So I switch it back to the
6476 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6478 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6479 so that we don't use the F_RELFLG which make the linker complain
6480 that somebody has stripped the relocation info.
6482 Also, the AIX ld program require that the relocation table
6483 is sorted by r_vaddr like the standard ATT assembler does.
6485 [he also changed the sizeof(struct ...)'s into the coff
6486 style FOOSZ macros. I'm not sure this is right, but I can't
6487 remember why. xoxorich.]
6489 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6491 * Makefile.in, configure.in, doc: use the doc. Build it, install
6494 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6496 * read.c: white space and comments only.
6498 * configure.in: use the new atof-ns32.c for ns32k.
6500 * write.c: comment change only.
6502 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6503 aren't yet integrated.
6505 * tc-i860.[hc]: blew off the dust. Something must still be done
6506 about conflicting relocation types.
6508 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6511 * tc-i960.c, tc-sparc.c: white space and comments only.
6513 * tc-a29k.h: delete duplicate macro definition.
6515 * new file atof-ns32k.c copied from hack's last unreleased gas.
6517 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6519 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6522 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6523 ChangeLog's prior to this are sketchy at best. I have logs.
6524 They just aren't ChangeLogs.
6528 version-control: never
