40 If PC-relative fixup refers to a PLT entry for a symbol in the
41 current section, don't reduce it.

88 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
89 not symbol_new, for symbols holding expression values.
90 * expr.h (make_expr_symbol): Move declaration here.
91 * write.c (fix_new_exp): Handle O_add by creating an
92 expression-valued symbol, and calling fix_new_exp recursively.
93 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
94 undefined symbol and a constant, fold the constant into the fixup,
95 and refer to the undefined symbol directly. Then process the
96 fixup again from scratch.
97 (write_object_file): Before calling adjust_reloc_syms, make a pass
98 through the symbol list trying to resolve values.
100 * write.c (print_fixup): New routine, for debugging.
101 (write_relocs): Call bfd_install_relocation. Deleted various
102 hacks for working around problems with bfd_perform_relocation.

119 * write.c (write_relocs): Add file name and line number to
120 as_fatal calls. Handle bfd_reloc_overflow case specifically when
121 RELOC_EXPANSION_POSSIBLE.
123 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
125 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
126 here. Use them for deciding which PRINTF*LIKE macro definitions
128 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.

130 default definitions matching what we were doing before.
131 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
132 always use the varargs form if not using stdarg. It's safe to
133 always use vfprintf, because libiberty will provide it if the
134 native system doesn't. Also, always make format be const.
135 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

150 (listing_newline): Check filename as well as line number when
151 deciding whether to record it.
152 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
153 false (if defined) as well as checking for reg_section.
154 (listing_listing): Iterate fetching lines while line number is too
155 low, and we haven't run off the end of the input file.
157 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.

184 (brtab_emit): Use data_section, not SEG_DATA.
186 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
188 * config/vms-conf.h: new file, manually derived from conf.in.
189 * config-gas.com: use it, and eliminate obsolete "host.h".

200 from the csect of the enclosing block.
202 * config/tc-mips.c (insns_since_cache_access): Remove.

208 * config/tc-mips.c (md_shortopts): Remove E.
209 (md_longopts): Add EB and EL.
210 (md_parse_option): Handle -EB and -EL as separate options, rather
211 than as a single -E option with an argument.
213 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
215 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
216 involving global symbols too.
218 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
220 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
222 * configure.in: Test for remove, not delete. Fix cross-assembler

234 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
235 many others): new macros; values obtained from "DSTRECRDS.SDL".
236 * config/obj-vms.h (various): use them.
237 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
238 representation (only enum bitfields can avoid being bitstrings).
239 (bitfield_suffix, setup_basic_type): new routines.
240 (VMS_typedef_parse): use them. Now recognize bitfields of all
241 integral types, not just type `int'. Caveat: the representation
242 used for bitfields still does not work for objects placed in
243 registers, and gcc's optimizer sometimes puts small structs there.
245 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
247 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
249 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
250 (tc_frob_label): define this to call vms_check_for_special_label,
251 and declare the latter.

254 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
255 (vms_check_for_special_label): new routine (tc_frob_label).
256 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
257 and `gcc2_compiled.' labels; they won't reach here any more.
258 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
259 double', use `vax_g_doubles' flag to select type of double.
260 (VMS_write_object_file) [traceback setup]: don't pass symbols
261 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
262 and TBT_Routine_End functions.
264 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
266 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
267 S_GET_VALUE() to avoid many repeated function calls.
268 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
269 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
270 gets requested. [All the HACK_DEC_C_STARTUP code appears to
271 be obsolete; gcc does it automatically for vms target. It's
272 also misnamed, because it is for the "VAX C" run-time library,
273 not the newer "DEC C" one which has much different startup code.]
274 {various}: use `S_SET_xxx(symbol,new_value)' rather than
275 `S_GET_xxx(symbol) = new_value'.

284 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
286 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
288 * expr.c (expr): Don't reduce the difference of two symbols in the
289 same frag if the symbols are not in normal sections.
291 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
292 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
293 (obj_attach_unwind_info): Do not define. Not needed anymore.
294 * config/tc-hppa.c: Delete whitespace at EOL.
295 (struct hppa_fix_struct): Delete fx_unwind field and all references.
296 (fix_new_hppa): Last arg is now a pointer to an int. Do not
297 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
298 fixups, store 32bits of unwind information in the fx_addnumber
300 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
301 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
302 pointer to 32 bits of unwind info.
303 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
304 pointer to the dummy symbol; set the addend field to fx_addnumber.
305 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
306 rather than &bfd_XXX_section.
308 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
310 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
311 value by one; discard adjustments previously being made. From
314 VMS- and Vax-related changes from Pat Rankin:
315 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
316 * vmsconf.sh: no longer have make-gas.com echo text about needing
317 to modify the gcc-vms driver when intending to use with gcc 1.x.
318 * as.c (parse_options): suppress 'v' from std_short_options and
319 eliminate VMS-specific conditional initialization;
320 [default case]: check for '-v' if md_parse_options doesn't recognize
322 [default case, #if VMS]: check for filename argument when '-v' seen;
324 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
325 for O_big literal operands (double floats and long long ints);
326 [VMS, md_shortopts]: add second colon after 'v';
327 (md_parse_options) [VMS, case 'v']: check for argument, so
328 caller can handle `-v' w/o arg.

379 Update for autoconf 1.118:
380 * gdbinit.in: New file, created from old .gdbinit.
382 * aclocal.m4 (GAS_GDBINIT): Deleted.
383 * configure.in: Don't use it. Instead, generate .gdbinit from
384 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
385 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
386 to ensure that older versions of autoconf aren't used.

438 fixup is not local, to prevent relocations against externals from
440 (md_assemble): Initialize disp_reloc field to NO_RELOC. Pass

1444 VMS debugger now recognizes `long long' variables correctly.
1445 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1446 for gcc2's predefined types "long double" (same as double, as
1447 per gcc's current state), "long long int", "long long unsigned
1448 int", and final `otherwise' case (to avoid uninitialized type
1449 and size fields). [caveat: predefined types "complex int",
1450 "complex float", "complex double", and "complex long double" are
1453 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
1454 of 0, because the latter indicates success rather than failure

1929 * config/tc-ppc.c (ppc_size): New static variable.
1930 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
1931 (md_begin): If an instruction has a size specific flag set, only

1967 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
1968 branch with an instruction that uses $at, in case the branch is

1972 to make it pcrel_offset.
1973 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to

1983 (md_assemble): Call it.
1984 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
1986 (lituse_pending): New variable. Set by anything that generates a
1987 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
1988 tested by code that might want to emit a LITUSE reloc.
1989 (emit_unaligned_io): New function. Currently calls md_assemble,
1990 but it should eventually be converted to generate the insn itself
1991 and call emit_insn directly.
1992 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
1993 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

2023 (macro): Handle EMBEDDED_PIC in all PIC cases.
2024 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2025 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2026 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2027 works). Do not permit -G with SVR4_PIC.
2028 (s_abicalls): Warn if -G was used, and force -G 0.
2029 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2030 anything but a.out, not just for ELF. For ECOFF, don't generate a

2041 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2043 * Makefile.in (config-stamp): If `defs' is defined, emit a
2044 preprocessor directive to create a macro named by this value into
2045 config.new; don't explicitly go for BFD_ASSEMBLER.
2046 * configure.in: Define `defs', not `BFDDEF'. Set it to
2047 MANY_SEGMENTS for any obj-coffbfd target.

2079 bfd_set_symtab is called.
2080 (dump_section_relocs): Note whether a symbol is a section symbol
2082 (adjust_reloc_syms): For now, always supply an absolute symbol for
2083 fixups without symbols but not yet `done'. Use section_symbol to
2084 get the symbol, instead of going directly for abs_symbol.
2085 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2086 reloc is not a section symbol and is not in the symbol table.
2087 (set_symtab): New function, broken out from write_object_file.
2088 Counts symbol table instead of relying on an earlier count.
2089 (write_object_file): Call set_symtab, but do it after potentially
2090 invoking the *_frob_file macros. Don't bother counting symbols.
2091 Call symbol_remove, instead of expanding it in place. Moved the
2092 conditionalized `object_file_size' declaration down to
2093 conditionalized block where it's used. When using the absolute
2094 symbol for a fixup without a symbol, set sy_used_in_reloc.
2095 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2096 the correct symbol for the absolute section.
2098 * subsegs.c (section_symbol): Use symbol_new instead of
2099 symbol_make, since we may want it to go into the symbol table.
2100 Make the new symbol have internal linkage. If
2101 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2102 symbol with the newly created GAS symbol.
2103 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2104 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2111 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2112 (sparc_ip, label "immediate"): Reject constants for pcrel
2113 instructions only if the relocation type indicates a "call"
2114 instruction and the offset is within range of a "jmpl %g0". If
2115 it's not in range, use the absolute section symbol plus an offset.
2116 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2118 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2120 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2123 * configure.in: Eliminated all targets using obj-coff but not
2124 defining BFD_ASSEMBLER; I think all such targets that are
2125 supported will be matched by real CPU-OS combinations earlier in
2127 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2128 some comments about the dpx2 configuration, but left it disabled,
2129 since it couldn't be reached before.
2130 (target a29k-amd-ebmonold): Deleted.
2132 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2140 the 'j' operand if there are no further alternatives for this
2143 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2144 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2145 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2147 * config/tc-mips.c (mips_align): Take new argument, label, and use
2148 it instead of global insn_label.
2149 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2150 call to mips_emit_delay and pass it to mips_align.
2152 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2154 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

2165 S_IS_EXTERNAL when deciding whether to discard a symbol.
2167 * config-gas.com: Scan Makefile.in, not version.c, for current

2172 values to reduce number of lookups with S_GET_VALUE. Skip debug
2173 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2174 holger@botbso.rhein-main.de.)
2175 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2176 field. (Also from Holger Teutsch.) Watch for a would-be register
2177 mask that spans frags.
2179 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2180 this_base, not line_base. (Patch from Andreas Arens,

2184 look local if they're exported or undefined. Used to be done for
2187 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

2189 the input stream, which is no longer null-terminated.
2190 (LEX_PCT): New macro, defaults to 0.
2191 (lex_type): Use it for `%'.
2193 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2243 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2244 0xffff for 'j' to be compatible with MIPS assembler. These

4318 default is to assume production environment, and reject configs
4319 still being worked on. Mark Elf configurations (except sparc and
4320 i386) as developmental. Deleted cases matching some generic names
4321 in favor of more specific names. (E.g., when we get Alpha

4348 are only used within tc-hppa.c static. PARAMize all functions.
4349 Add comments to functions. Delete unused functions, variables,
4350 #defines, etc. Delete unused members within structures. Delete
4351 ldil;ble hacks -- it is believed they were installed to work
4352 around old gas bugs. Avoid using mixed case for local
4353 functions, variables, and structures. Fix formatting problems
4354 not found by GNU-indent. Add FIXME notices for things which
4355 should be worked on the near future. Delete lots of old
4356 useless (1.36 PA-SOM) code.

4435 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4437 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4438 ELF, since the ELF object format does not have these type of
4439 relocations. Change the abort into as as_bad and return
4440 BFD_RELOC_NONE to silence compiler warnings.
4441 (md_assemble): Keep track of the instruction size. Allow white
4442 space between the $ and the constant for compatibility with older
4443 gases and other assemblers.

6887 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

6894 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

6927 dropping a space immediately following an identifier.

6929 lines; I don't think that can be done portably.
6930 * config/tc-mips.c (macro): Use $AT if target register is zero in

7055 * make-gas.com: Find obstack.obj if it's not in the current
7057 * read.c (s_ignore): Don't declare is_end_of_line. It's
7058 redundant, and triggers a VMS gcc compiler bug.

7061 current segment as an argument. (Ignored in all cases but VMS.)
7062 All callers and definitions changed.

7120 (zero_address_frag, bss_address_frag): Now initialized at run
7122 * as.c (main): Call frag_init.

7393 (operand): Treat zero byte as end-of-operand.
7395 * configure.in (per-target): Look for with_bfd_assembler option.
7396 For now, only accept "no", until the merge is done.
7398 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7399 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

7405 * expr.c: Add "const" modifier to hex_value.
7406 * symbols.c: Finish conversion to S_* macros in the VMS only
7407 parts of the program. Add "const" modifier to
7408 md_[long,short]_jump_size. Remove declaration of const_flag
7409 (which will be declared in obj-vms.h).
7410 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7411 Fix arguments to VMS_write_object_file.
7412 * config-gas.com: New file. Script for VMS systems to set up the
7413 configuration to build gas for VMS, and create config.status.

7421 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7422 types of malformed stabs. Change parsing algorithm so that we are
7423 more certain of having all of the information that we need on hand.

7474 if these are used or defined, if BFD_ASSEMBLER.
7475 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7476 subseg_new split into two functions.
7477 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7479 * as.h (volatile): Don't define if already defined.
7480 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7482 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7483 declare with format attribute for -Wformat checking.
7485 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7487 * app.c, config/tc-*.c: Don't include read.h, since it is already
7490 * These are based on patches from Minh Tran-le
7491 <mtranle@paris.intellicorp.com>.
7492 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7493 obj_format coffbfd and gas_target i386coff for target.
7494 (i[34]86-*-isc*): New host (uses sysv).
7495 * config/i386aix.mt: Removed (no longer used).
7496 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7498 (LDFLAGS): Added, defined as -shlib.
7499 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7500 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7501 (DOT_LABEL_PREFIX): Define.
7502 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7503 name rather than L0\001.
7504 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7506 * symbols.c, symbols.h (local_bss_counter): Removed.
7507 * write.c (write_object_file): bss no longer uses
7508 local_bss_counter. Pass correct data and bss size to
7509 VMS_write_object_file.

7513 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
7514 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
7515 (size_section): Restored sanity check.
7516 (do_relocs_for): Base section address on s_paddr rather than
7517 computing it. Adjust a29k R_IHIHALF special case to account for
7518 section paddr (used to require paddr to be zero). If there are no
7519 reclos, set s_relptr to 0. Set relocation size in object_headers.
7520 (fill_section): Always set s_vaddr here, removing
7521 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7522 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7523 Set STYP_INFO for .comment.
7524 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7525 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7527 H_{SET,GET}_* macros.
7528 (do_linenos_for): Set lineno size in object_headers.
7529 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7530 set s_vaddr here. If string_byte_count remains 4, set it back to
7531 0, and only write strings out if there are some. Call
7532 fill_section before do_relocs_for and do_linenos_for.
7533 (obj_coff_section): Handle optional quoted second argument giving
7534 section characteristics.
7535 (obj_coff_bss): Added to handle .bss.
7536 (obj_coff_ident): Added to handle .ident (puts string in .comment
7538 (obj_coff_lcomm): Put common symbols in .bss, not .data.
7539 (fixup_mdeps): Change to segment. Call frag_wane after
7541 (fixup_segment): Explicitly check S_IS_COMMON before making 386
7542 adjustment (already happened only for common symbols, but this is
7544 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
7545 * config/tc-i386.c (s_bss): Don't use if I386COFF.

7556 (do_scrub_next_char): For \", return " not '.
7557 (symbol_chars): Now const.
7559 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7560 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7562 * config/obj-coff.h: Don't use #elif.
7564 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7565 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

7592 using ZERO_BASED_SEGMENTS.
7593 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7594 never set segment address for SEG_E2 (.bss) and don't write out
7595 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7596 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7597 definitions, and don't merge tags with non-tags. Check for .bf
7598 rather than just checking whether the second character is b and
7599 the third character is f.
7600 (obj_coff_val): gcc can generate values which we don't handle
7601 correctly; discard information for now, since it only affects the
7602 debugging information.
7603 (tag_find_or_name): Don't insert tags in the symbol table.
7604 (yank_symbols): Don't merge labels.
7605 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7750 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
7751 could be doing emulation.
7753 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7756 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

7785 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7787 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
7788 constant will not fit in an immediate field.
7789 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

7824 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
7826 * Support for i386-sysv.
7827 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7851 * tc-m68k.c (get_num): make it work for all segments, not just the
7854 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
7856 * configure.in: recognize i386-*-bsd emulation.

7865 * tc-z8k.c: lots of bug fixes
7867 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7869 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7870 #elif, since it is not supported by old compilers.
7871 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7872 couple of expressions in tc-m68k.c.
7874 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7876 * read.c (cons): If NO_RELOC is defined, use it.
7878 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
7880 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
7882 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
7883 local labels to start with a .) and set REGISTER_PREFIX to %.
7884 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
7886 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
7888 * messages.c: Comment changes.
7890 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

7893 * messages.c: If __STDC__ is not defined, define NO_STDARG.
7895 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
7897 * listing.c (debugging_pseudo): Add stabs and stabn as things to
7900 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7902 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7903 sections starting from zero, rather than making them consecutive.
7904 This makes subsequent reloc calculations easier, esp if the object
7905 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7906 allocate lcomm in .data rather than in .bss. It seems that some
7907 tools can't cope with a non-zero sized bss before linkage.
7909 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7911 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
7912 throughout. That enum no longer means what we thought it meant.
7914 * tc-m68k.c (md_assemble, md_parse_option): Handle new
7915 "-mno-688[58]1" options.
7917 * tc-m68k.c: Added CPU32 support.
7919 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

7925 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
7926 Change LIBDEPS dependence to LIBS.
7928 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
7930 * Makefile.in (install): if $(tooldir) exists, install as in
7933 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7935 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7936 .word is < -32768 or > 32767. The -J flag causes the error to be
7937 ignored. This is to catch over-sized switches generated by gcc on
7938 systems which don't support the broken .word hack.
7939 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7940 write.c (fixup_segment): check for signed .word overflow if
7941 WARN_SIGNED_OVERFLOW_WORD.
7943 * write.c (fixup_segment): fixed missing parens in expression
7944 checking for byte or word overflow.
7946 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
7947 obj-coffbfd.c (fixup_segment): check for signed .word overflow if

7956 * obj-coffbfd.h : added stuff
7957 * tc-i386.c (tc_coff_fix2rtype): new function
7958 * tc-i386.h : new coff defines
7960 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)

7974 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
7975 Motorola and MIT syntax; gas can now assemble either type of

8057 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8058 written with indirection on the last two operands, which can be
8059 either data or address registers. Added a new operand type 'r'
8060 which accepts either register type. Added '(' to notend stuff in
8061 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8400 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8402 * expr.c: If an expression is single comma, then return with
8403 SEG_ABSENT rather than an error - since the sparc front end does
8404 really strange things with things like fbge,a
8406 * as.h: include bfd.h if using many sections
8407 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so

8416 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8418 * app.c: MRI compatibility - allow single quote to start a string.

8420 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8421 * expr.c: Much rewriting, to accomodate MRI syntax for
8422 expressions. Also easier to read now.
8423 * listing.c: Put back defuns
8424 * read.c: modified to accept MRI syntax, put back listing pseudo
8425 ops so that an assembler built with NO_LISTING ignores list ops
8427 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8428 machine is a SPARC or a 29K.
8429 * config/obj-aout.c: added s_sect pseudo op
8430 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8431 fill in the timestamp.
8432 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8433 anymore, define all the relocs which the tc-<x> bit will use so we
8434 can translate from them to the coff types.
8435 * config/tc-a29k.c: reloc_type isn't ane enum any more
8436 * config/tc-m68k.c: Added NO_RELOC definition.
8438 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)

8451 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8453 * symbols.c (local_label_name): symbols now start with ^A.
8455 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8456 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8457 generate these sections. .align: will use NOP_OPCODE or 0
8458 for padding. This is just for being nice to the
8461 * expr.c (operand): changed to generate local label "\001L0"
8462 starting with a ^A so that it is recognized as a local label.
8464 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8466 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8467 i/o opcodes - inb, inw, outb and outw. string manipulation with
8468 att syntax - scmp, slod, smov, ssca, ssto.
8470 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8471 to just after .file .
8473 In obj_crawl_symbol_chain() where it tries to put the external
8474 symbols apart, with the condition:
8475 (!S_IS_DEFINED(symbolP) &&
8476 !S_IS_DEBUG(symbolP) &&
8477 !SF_GET_STATICS(symbolP))
8478 it was moving too many symbols out. So I switch it back to the
8480 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8482 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8483 so that we don't use the F_RELFLG which make the linker complain
8484 that somebody has stripped the relocation info.
8486 Also, the AIX ld program require that the relocation table
8487 is sorted by r_vaddr like the standard ATT assembler does.
8489 [he also changed the sizeof(struct ...)'s into the coff
8490 style FOOSZ macros. I'm not sure this is right, but I can't
8491 remember why. xoxorich.]

8495 * Makefile.in, configure.in, doc: use the doc. Build it, install
8498 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8500 * read.c: white space and comments only.
8502 * configure.in: use the new atof-ns32.c for ns32k.
8504 * write.c: comment change only.
8506 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8507 aren't yet integrated.
8509 * tc-i860.[hc]: blew off the dust. Something must still be done
8510 about conflicting relocation types.
8512 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8515 * tc-i960.c, tc-sparc.c: white space and comments only.
8517 * tc-a29k.h: delete duplicate macro definition.
8519 * new file atof-ns32k.c copied from hack's last unreleased gas.
8521 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8523 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8526 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8527 ChangeLog's prior to this are sketchy at best. I have logs.
8528 They just aren't ChangeLogs.
