30 expressions that couldn't be reduced to constants when initially
32 (elf_frob_symbol): Declare.
33 (obj_frob_symbol): Call elf_frob_symbol always, rather than
34 ecoff_frob_symbol only if ECOFF_DEBUGGING defined.

59 (obj_coff_line): Only reset line_base for .bf symbols.
60 * config/obj-coff.h (coff_adjust_section_syms, coff_frob_file):
62 (obj_frob_file): New macro.
64 * config/obj-coff.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Renamed from

121 (fixup_segment): Changed local var PCREL to type int, added PLT.
122 If PC-relative fixup refers to a PLT entry for a symbol in the
123 current section, don't reduce it.

126 DEBUG5 is defined, print out each fixup before and after
128 (fixup_segment): If DEBUG5 is defined, print out each fixup before
129 and after processing.

139 * Makefile.in (all): Depend on .gdbinit.
140 (.gdbinit): Rebuild from gdbinit.in by running config.status.
142 * gdbinit.in: Define new function "pf". Fix doc on "pe" and "ps".
144 * write.c (print_fixup): Print source location on first line.
145 Show fx_r_type and fx_addsy fields.
147 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
149 * configure.in: Set bfd_gas for all sparc targets in one place,

155 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
158 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
159 processing if add_symbol is undefined or in expr_section.
160 (resolve_symbol_value, case O_add): For symbol plus
161 constant-valued symbol, convert to O_symbol and re-reduce.

168 (print_expr_1): Fix whitespace before printing X_add_number.
170 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
171 not symbol_new, for symbols holding expression values.
172 * expr.h (make_expr_symbol): Move declaration here.
173 * write.c (fix_new_exp): Handle O_add by creating an
174 expression-valued symbol, and calling fix_new_exp recursively.
175 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
176 undefined symbol and a constant, fold the constant into the fixup,
177 and refer to the undefined symbol directly. Then process the
178 fixup again from scratch.
179 (write_object_file): Before calling adjust_reloc_syms, make a pass
180 through the symbol list trying to resolve values.
182 * write.c (print_fixup): New routine, for debugging.
183 (write_relocs): Call bfd_install_relocation. Deleted various
184 hacks for working around problems with bfd_perform_relocation.

188 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
190 * Makefile.in (gasp.o): Depends upon config.h.
192 * config/tc-mips.c: Include subsegs.h.
193 (md_apply_fix): If an unconditional b or bal overflows, and we are
194 not assembling PIC code, replace it with a j or jal.
196 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
197 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
199 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
201 * write.c (write_relocs): Add file name and line number to
202 as_fatal calls. Handle bfd_reloc_overflow case specifically when
203 RELOC_EXPANSION_POSSIBLE.
205 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
207 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
208 here. Use them for deciding which PRINTF*LIKE macro definitions
210 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
211 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
212 default definitions matching what we were doing before.
213 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
214 always use the varargs form if not using stdarg. It's safe to
215 always use vfprintf, because libiberty will provide it if the
216 native system doesn't. Also, always make format be const.
217 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
219 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

232 (listing_newline): Check filename as well as line number when
233 deciding whether to record it.
234 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
235 false (if defined) as well as checking for reg_section.
236 (listing_listing): Iterate fetching lines while line number is too
237 low, and we haven't run off the end of the input file.
239 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
241 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

252 * symbols.c (copy_symbol_attributes): New function. Copies BFD
253 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
254 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
255 zero. Don't call obj_frob_forward_symbol.

258 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
260 * config/tc-i960.c: Lots of whitespace, comment reformatting,
262 (strchr): Don't declare.

264 md_estimate_size_before_relax, md_ri_to_chars,
265 md_create_short_jump, md_create_long_jump.
266 (brtab_emit): Use data_section, not SEG_DATA.
268 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
270 * config/vms-conf.h: new file, manually derived from conf.in.
271 * config-gas.com: use it, and eliminate obsolete "host.h".
273 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
275 * config/tc-ppc.c (ppc_current_block): New static variable.

280 (ppc_es): Clear ppc_current_block.
281 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
282 from the csect of the enclosing block.
284 * config/tc-mips.c (insns_since_cache_access): Remove.
285 (append_insn): Remove setting of insns_since_cache_access, and

288 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
290 * config/tc-mips.c (md_shortopts): Remove E.
291 (md_longopts): Add EB and EL.
292 (md_parse_option): Handle -EB and -EL as separate options, rather
293 than as a single -E option with an argument.
295 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
297 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
298 involving global symbols too.
300 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
302 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
304 * configure.in: Test for remove, not delete. Fix cross-assembler
306 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
309 * read.c (pseudo_set, case O_symbol): If
310 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
311 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.

314 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
316 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
317 many others): new macros; values obtained from "DSTRECRDS.SDL".
318 * config/obj-vms.h (various): use them.
319 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
320 representation (only enum bitfields can avoid being bitstrings).
321 (bitfield_suffix, setup_basic_type): new routines.
322 (VMS_typedef_parse): use them. Now recognize bitfields of all
323 integral types, not just type `int'. Caveat: the representation
324 used for bitfields still does not work for objects placed in
325 registers, and gcc's optimizer sometimes puts small structs there.
327 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
329 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
331 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
332 (tc_frob_label): define this to call vms_check_for_special_label,
333 and declare the latter.
334 * config/obj-vms.c (vax_g_doubles): declare this file-scope
336 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
337 (vms_check_for_special_label): new routine (tc_frob_label).
338 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
339 and `gcc2_compiled.' labels; they won't reach here any more.
340 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
341 double', use `vax_g_doubles' flag to select type of double.
342 (VMS_write_object_file) [traceback setup]: don't pass symbols
343 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
344 and TBT_Routine_End functions.
346 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
348 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
349 S_GET_VALUE() to avoid many repeated function calls.
350 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
351 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
352 gets requested. [All the HACK_DEC_C_STARTUP code appears to
353 be obsolete; gcc does it automatically for vms target. It's
354 also misnamed, because it is for the "VAX C" run-time library,
355 not the newer "DEC C" one which has much different startup code.]
356 {various}: use `S_SET_xxx(symbol,new_value)' rather than
357 `S_GET_xxx(symbol) = new_value'.
359 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
361 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
362 not &bfd_abs_section.
364 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
366 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
368 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
370 * expr.c (expr): Don't reduce the difference of two symbols in the
371 same frag if the symbols are not in normal sections.
373 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
374 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
375 (obj_attach_unwind_info): Do not define. Not needed anymore.
376 * config/tc-hppa.c: Delete whitespace at EOL.
377 (struct hppa_fix_struct): Delete fx_unwind field and all references.
378 (fix_new_hppa): Last arg is now a pointer to an int. Do not
379 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
380 fixups, store 32bits of unwind information in the fx_addnumber
382 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
383 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
384 pointer to 32 bits of unwind info.
385 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
386 pointer to the dummy symbol; set the addend field to fx_addnumber.
387 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
388 rather than &bfd_XXX_section.
390 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
392 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
393 value by one; discard adjustments previously being made. From
396 VMS- and Vax-related changes from Pat Rankin:
397 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
398 * vmsconf.sh: no longer have make-gas.com echo text about needing
399 to modify the gcc-vms driver when intending to use with gcc 1.x.
400 * as.c (parse_options): suppress 'v' from std_short_options and
401 eliminate VMS-specific conditional initialization;
402 [default case]: check for '-v' if md_parse_options doesn't recognize
404 [default case, #if VMS]: check for filename argument when '-v' seen;
406 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
407 for O_big literal operands (double floats and long long ints);
408 [VMS, md_shortopts]: add second colon after 'v';
409 (md_parse_options) [VMS, case 'v']: check for argument, so
410 caller can handle `-v' w/o arg.

414 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET

424 * hex-value.c: Ditto.
425 * config/obj-vms.c: Ditto.
427 * config/tc-sparc.c (sparc_ip): Replace as_bad/exit sequence with

451 (parse_args): Use them always.
452 (main): Use exit rather than return.
454 * Makefile.in (*_FOR_TARGET, INSTALL_XFORM, install, uninstall):
455 Rewrite handling of program_transform_name.
457 * configure.in: Test for functions unlink and delete.
458 * as.h: If unlink isn't available but delete is, define unlink to
461 Update for autoconf 1.118:
462 * gdbinit.in: New file, created from old .gdbinit.
464 * aclocal.m4 (GAS_GDBINIT): Deleted.
465 * configure.in: Don't use it. Instead, generate .gdbinit from
466 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
467 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
468 to ensure that older versions of autoconf aren't used.
469 * Makefile.in: Added @configure_input@ line.

1903 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
1905 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>

1929 argument, the reloc type.
1930 (load_register): Pass reloc type to macro_build for 'u'.
1931 (macro): Likewise. For M_LA_AB permit a difference expression
1932 when generating embedded PIC code between an arbitrary symbol and

1975 (hppa_tc_symbol): Likewise.
1977 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
1978 elf_tc_make_sections stuff. It was there to support PA braindamage
1979 which has been fixed, and in the case of elf_tc_make_sections is
1980 redundant with elf_tc_final_processing.
1982 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1984 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

2000 don't spew remainder of input file in error message.
2001 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2002 message with reloc type and try to process remainder of file.

2010 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
2012 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2014 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2015 flag rather than signedp field. Only permit extended range if
2016 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2017 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2019 * config/tc-ppc.c (ppc_size): New static variable.
2020 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2021 (md_begin): If an instruction has a size specific flag set, only
2022 add it if we are assembling that size.

2026 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2027 cross section PC relative relocs right for COFF and ELF.
2029 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2031 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

2036 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2037 the type of symbol set symbols which happen to be in the absolute
2038 or undefined section.

2042 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2043 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2044 and -many (all architectures).

2048 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
2049 involving a function symbol which is not a plabel to zero.
2050 (md_apply_fix): Never pass a function symbol to field_adjust.

2054 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2055 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2057 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2058 branch with an instruction that uses $at, in case the branch is
2060 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2061 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2062 to make it pcrel_offset.
2063 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2064 reloc->address; another gruesome hack to get gas reloc handling to
2067 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2069 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2072 (emit_insn): New function.
2073 (md_assemble): Call it.
2074 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2076 (lituse_pending): New variable. Set by anything that generates a
2077 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2078 tested by code that might want to emit a LITUSE reloc.
2079 (emit_unaligned_io): New function. Currently calls md_assemble,
2080 but it should eventually be converted to generate the insn itself
2081 and call emit_insn directly.
2082 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2083 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2084 emit_bis_r): Likewise.
2085 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2086 (alpha_ip, label get_macro): Don't emit the final instruction if
2088 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2089 unaligned memory access macros.
2090 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2091 the value can't be resolved.
2093 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2095 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2096 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2097 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2109 * config/tc-mips.c (enum mips_pic_level): New enum.
2110 (mips_pic): Change from int to enum mips_pic_level. Change all
2111 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2112 (load_address): Handle EMBEDDED_PIC.
2113 (macro): Handle EMBEDDED_PIC in all PIC cases.
2114 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2115 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2116 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2117 works). Do not permit -G with SVR4_PIC.
2118 (s_abicalls): Warn if -G was used, and force -G 0.
2119 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2120 anything but a.out, not just for ELF. For ECOFF, don't generate a
2121 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2123 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2125 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2127 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2128 parameters to avoid losing when compiling with HP CC.

2131 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2133 * Makefile.in (config-stamp): If `defs' is defined, emit a
2134 preprocessor directive to create a macro named by this value into
2135 config.new; don't explicitly go for BFD_ASSEMBLER.
2136 * configure.in: Define `defs', not `BFDDEF'. Set it to
2137 MANY_SEGMENTS for any obj-coffbfd target.
2138 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2139 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2141 (LOCAL_LOADLIBES): Deleted.
2142 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2143 * config/m88kcoff.mt (TDEFINES): Ditto.
2144 * config/ebmon29k.mt: Deleted.

2169 bfd_set_symtab is called.
2170 (dump_section_relocs): Note whether a symbol is a section symbol
2172 (adjust_reloc_syms): For now, always supply an absolute symbol for
2173 fixups without symbols but not yet `done'. Use section_symbol to
2174 get the symbol, instead of going directly for abs_symbol.
2175 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2176 reloc is not a section symbol and is not in the symbol table.
2177 (set_symtab): New function, broken out from write_object_file.
2178 Counts symbol table instead of relying on an earlier count.
2179 (write_object_file): Call set_symtab, but do it after potentially
2180 invoking the *_frob_file macros. Don't bother counting symbols.
2181 Call symbol_remove, instead of expanding it in place. Moved the
2182 conditionalized `object_file_size' declaration down to
2183 conditionalized block where it's used. When using the absolute
2184 symbol for a fixup without a symbol, set sy_used_in_reloc.
2185 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2186 the correct symbol for the absolute section.
2188 * subsegs.c (section_symbol): Use symbol_new instead of
2189 symbol_make, since we may want it to go into the symbol table.
2190 Make the new symbol have internal linkage. If
2191 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2192 symbol with the newly created GAS symbol.
2193 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2194 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2201 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2202 (sparc_ip, label "immediate"): Reject constants for pcrel
2203 instructions only if the relocation type indicates a "call"
2204 instruction and the offset is within range of a "jmpl %g0". If
2205 it's not in range, use the absolute section symbol plus an offset.
2206 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2208 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2210 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2213 * configure.in: Eliminated all targets using obj-coff but not
2214 defining BFD_ASSEMBLER; I think all such targets that are
2215 supported will be matched by real CPU-OS combinations earlier in
2217 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2218 some comments about the dpx2 configuration, but left it disabled,
2219 since it couldn't be reached before.
2220 (target a29k-amd-ebmonold): Deleted.
2222 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2230 the 'j' operand if there are no further alternatives for this
2233 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2234 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2235 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2237 * config/tc-mips.c (mips_align): Take new argument, label, and use
2238 it instead of global insn_label.
2239 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2240 call to mips_emit_delay and pass it to mips_align.
2242 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2244 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2246 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2247 argument to a .callinfo directive. Don't loop forever on errors.
2249 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2250 use pre-defined registers as arguments.

2262 values to reduce number of lookups with S_GET_VALUE. Skip debug
2263 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2264 holger@botbso.rhein-main.de.)
2265 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2266 field. (Also from Holger Teutsch.) Watch for a would-be register
2267 mask that spans frags.
2269 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2270 this_base, not line_base. (Patch from Andreas Arens,
2271 ari@obelix.av.rwth-aachen.de.)
2273 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2274 look local if they're exported or undefined. Used to be done for
2277 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2278 Get it from the looked-up symbol, instead of using the string from
2279 the input stream, which is no longer null-terminated.
2280 (LEX_PCT): New macro, defaults to 0.
2281 (lex_type): Use it for `%'.
2283 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2333 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2334 0xffff for 'j' to be compatible with MIPS assembler. These
2335 numbers are actually treated as negative.

3918 Delete dead code. Simplify.
3919 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
3920 applied are in range. Use bfd_put_32 rather than inserting each

4036 an example of marker relocations.
4037 * write.c (write_relocs): Instead of assuming size of a relocation
4038 is 4 bytes, pick up the size from relocation itself.

4068 pass new argument for i, j and o cases.
4069 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

4290 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4291 the table, require that the one without bit 0x1000000 set come
4292 first. Require further that it be case 'b' or 'P'. The a29k
4293 opcode table already meets these constraints.
4294 (machine_ip): When handling case 'i' or 'A', make sure that the
4295 appropriate opcode really exists by looking at the next entry in

4404 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4406 * configure.in: Set bfd_gas for all sparc targets. Added facility
4407 for keeping or rejecting configurations still under development;
4408 default is to assume production environment, and reject configs
4409 still being worked on. Mark Elf configurations (except sparc and
4410 i386) as developmental. Deleted cases matching some generic names
4411 in favor of more specific names. (E.g., when we get Alpha

4428 through inclusion of tc-hppa.h. Delete all forward declarations
4429 for functions only used within tc-hppa.c, likewise for structures,
4430 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4431 conditional code in a few small places.
4433 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4434 structures, global variables, forward declarations together.

4436 conditional code -- try to group conditional code together
4437 into a few places. Make all functions and variables which
4438 are only used within tc-hppa.c static. PARAMize all functions.
4439 Add comments to functions. Delete unused functions, variables,
4440 #defines, etc. Delete unused members within structures. Delete
4441 ldil;ble hacks -- it is believed they were installed to work
4442 around old gas bugs. Avoid using mixed case for local
4443 functions, variables, and structures. Fix formatting problems
4444 not found by GNU-indent. Add FIXME notices for things which
4445 should be worked on the near future. Delete lots of old
4446 useless (1.36 PA-SOM) code.
4448 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
4449 field of the fixS structure. Needed to build unwind
4450 descriptors correctly.

4474 * config/tc-hppa.c: (md_section_align): Align all sections to
4475 a multiple of the section alignment rather than always a
4478 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4479 bits are zero (eg they specify no relocations), then do not even
4480 bother adding their entries to thesymextn section.

4524 of text, data and bss sections to 4.
4525 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4527 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4528 ELF, since the ELF object format does not have these type of
4529 relocations. Change the abort into as as_bad and return
4530 BFD_RELOC_NONE to silence compiler warnings.
4531 (md_assemble): Keep track of the instruction size. Allow white
4532 space between the $ and the constant for compatibility with older
4533 gases and other assemblers.
4534 (i386_operand): Skip spaces between $ and expression.

5578 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
5579 case to set obj_format=elf. Must go before i386-*-sysv* case that
5580 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
5581 *-*-solaris case, and move to before *-sysv* case that wants to
5582 set obj_format to coff.

5608 * Extensive changes to permit symbols to contain any expression
5609 type and to delay the computation of the expression until the
5610 value is actually needed. This permits setting symbols to values
5611 calculated based on object code size. Expressions were changed to
5612 no longer be in a section, to stop the overloading of segment and
5613 expression type that previously occurred.
5615 * as.c (big_section, pass1_section, diff_section, absent_section):
5617 (expr_section): Added (used for dummy symbols which hold

5701 (previous_section, previous_subsection): New vars.
5702 (obj_elf_section): Save current place in case DWARF code wants us
5703 to pop back to it. Handle unquoted section name as well as quoted
5704 section name. Don't crash on invalid strings.
5705 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
5708 * config/obj-elf.h: Don't include struc-symbol.h.

5817 sy_resolved and sy_resolving single bit fields.
5818 * symbols.c (symbol_new): Don't initialize sy_forward field.

7019 lines; I don't think that can be done portably.
7020 * config/tc-mips.c (macro): Use $AT if target register is zero in
7021 load instruction, which it can be for a floating point load.

7095 prototypes for all static functions. Moved existing minimal
7096 debugging format support info #ifndef OBJ_ECOFF blocks.

7145 * make-gas.com: Find obstack.obj if it's not in the current
7147 * read.c (s_ignore): Don't declare is_end_of_line. It's
7148 redundant, and triggers a VMS gcc compiler bug.
7150 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7151 current segment as an argument. (Ignored in all cases but VMS.)
7152 All callers and definitions changed.

7176 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7179 * configure.in: mips-bsd configuration was missing format spec.
7182 * Makefile.in (Makefile): Depends on configure.in.
7184 * config/tc-mips.c (append_insn): Don't check for alignment of
7185 frag in memory; alignment of instructions in section is a separate

7206 constants are accepted, but symbolic values are not. GCC will not
7207 generate the latter currently.
7209 * frags.c (frag_init): New function.
7210 (zero_address_frag, bss_address_frag): Now initialized at run
7212 * as.c (main): Call frag_init.

7488 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7489 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7490 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7491 * read.c: Finish conversion to S_* macros in the VMS only
7492 parts of the program. Add "const" modifier to hex_value.
7493 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7495 * expr.c: Add "const" modifier to hex_value.
7496 * symbols.c: Finish conversion to S_* macros in the VMS only
7497 parts of the program. Add "const" modifier to
7498 md_[long,short]_jump_size. Remove declaration of const_flag
7499 (which will be declared in obj-vms.h).
7500 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7501 Fix arguments to VMS_write_object_file.
7502 * config-gas.com: New file. Script for VMS systems to set up the
7503 configuration to build gas for VMS, and create config.status.
7504 * make-gas.com: Redone to work with new scheme.
7505 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
7507 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
7508 will swap bytes if needed on a big endian system. Use throughout
7510 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7511 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7512 types of malformed stabs. Change parsing algorithm so that we are
7513 more certain of having all of the information that we need on hand.
7514 * obj-vms.c (final_forward_reference): New function, used to help
7515 resolve the data types of as many struct elements as possible
7516 when some part of the struct is not fully defined by the compiler.
7517 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
7519 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7520 as symbols as well in the object file. Look for external functions
7521 that start with "__vt.", and turn them into variables, since the
7522 g++ compiler is incapable of doing this.
7523 * tc-vax.c: Add '1' option for backward compatibility with older GCC
7525 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
7526 * input-scrub.c (as_where): Fix bug where as would crash if we did not
7527 have the name of the source file yet.
7528 * config/ho-vms.h: define HO_VMS, not HO_VAX.
7530 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
7532 * read.c (s_data): Always use "data_section", since it'll map to
7533 SEG_DATA or SEG_E1 if needed.
7534 (s_lcomm): Likewise with bss_section.
7535 (s_fill): Use memset, not bzero.
7537 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
7539 * read.c: Deleted some code under "#ifdef DONTDEF" that was for
7540 handling GDB symbol table data.

7553 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
7554 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

7558 (section_alignment): Declare only if not BFD_ASSEMBLER.
7559 (big_section, reg_section, pass1_section, diff_section,
7560 absent_section, text_section, data_section, bss_section): If
7561 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7562 mapping to segT enum values.
7563 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7564 if these are used or defined, if BFD_ASSEMBLER.
7565 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7566 subseg_new split into two functions.
7567 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7569 * as.h (volatile): Don't define if already defined.
7570 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7572 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7573 declare with format attribute for -Wformat checking.
7575 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7577 * app.c, config/tc-*.c: Don't include read.h, since it is already
7580 * These are based on patches from Minh Tran-le
7581 <mtranle@paris.intellicorp.com>.
7582 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7583 obj_format coffbfd and gas_target i386coff for target.
7584 (i[34]86-*-isc*): New host (uses sysv).
7585 * config/i386aix.mt: Removed (no longer used).
7586 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7588 (LDFLAGS): Added, defined as -shlib.
7589 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7590 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7591 (DOT_LABEL_PREFIX): Define.
7592 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7593 name rather than L0\001.
7594 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7596 * symbols.c, symbols.h (local_bss_counter): Removed.
7597 * write.c (write_object_file): bss no longer uses
7598 local_bss_counter. Pass correct data and bss size to
7599 VMS_write_object_file.

7604 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
7605 (size_section): Restored sanity check.
7606 (do_relocs_for): Base section address on s_paddr rather than
7607 computing it. Adjust a29k R_IHIHALF special case to account for
7608 section paddr (used to require paddr to be zero). If there are no
7609 reclos, set s_relptr to 0. Set relocation size in object_headers.
7610 (fill_section): Always set s_vaddr here, removing
7611 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7612 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7613 Set STYP_INFO for .comment.
7614 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7615 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7617 H_{SET,GET}_* macros.
7618 (do_linenos_for): Set lineno size in object_headers.
7619 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7620 set s_vaddr here. If string_byte_count remains 4, set it back to
7621 0, and only write strings out if there are some. Call
7622 fill_section before do_relocs_for and do_linenos_for.
7623 (obj_coff_section): Handle optional quoted second argument giving
7624 section characteristics.
7625 (obj_coff_bss): Added to handle .bss.
7626 (obj_coff_ident): Added to handle .ident (puts string in .comment

7629 (fixup_mdeps): Change to segment. Call frag_wane after
7631 (fixup_segment): Explicitly check S_IS_COMMON before making 386
7632 adjustment (already happened only for common symbols, but this is
7634 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
7635 * config/tc-i386.c (s_bss): Don't use if I386COFF.

7646 (do_scrub_next_char): For \", return " not '.
7647 (symbol_chars): Now const.
7649 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7650 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7652 * config/obj-coff.h: Don't use #elif.
7654 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7655 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

7681 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7682 using ZERO_BASED_SEGMENTS.
7683 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7684 never set segment address for SEG_E2 (.bss) and don't write out
7685 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7686 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7687 definitions, and don't merge tags with non-tags. Check for .bf
7688 rather than just checking whether the second character is b and
7689 the third character is f.
7690 (obj_coff_val): gcc can generate values which we don't handle
7691 correctly; discard information for now, since it only affects the
7692 debugging information.

7694 (yank_symbols): Don't merge labels.
7695 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7959 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7960 #elif, since it is not supported by old compilers.
7961 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7962 couple of expressions in tc-m68k.c.
7964 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7966 * read.c (cons): If NO_RELOC is defined, use it.
7968 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
7970 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
7972 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
7973 local labels to start with a .) and set REGISTER_PREFIX to %.
7974 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
7976 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

7987 * listing.c (debugging_pseudo): Add stabs and stabn as things to
7990 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7992 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7993 sections starting from zero, rather than making them consecutive.
7994 This makes subsequent reloc calculations easier, esp if the object
7995 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7996 allocate lcomm in .data rather than in .bss. It seems that some
7997 tools can't cope with a non-zero sized bss before linkage.
7999 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8001 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8002 throughout. That enum no longer means what we thought it meant.

8005 "-mno-688[58]1" options.
8007 * tc-m68k.c: Added CPU32 support.

8020 * Makefile.in (install): if $(tooldir) exists, install as in
8023 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8025 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8026 .word is < -32768 or > 32767. The -J flag causes the error to be
8027 ignored. This is to catch over-sized switches generated by gcc on
8028 systems which don't support the broken .word hack.
8029 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8030 write.c (fixup_segment): check for signed .word overflow if
8031 WARN_SIGNED_OVERFLOW_WORD.
8033 * write.c (fixup_segment): fixed missing parens in expression
8034 checking for byte or word overflow.
8036 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
8037 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
8038 WARN_SIGNED_OVERFLOW_WORD.

8048 * tc-i386.h : new coff defines
8050 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8052 * input-scrub.c (input_scrub_push): call input_file_begin, not
8054 messages.c (as_perror): print ": " between the passed in error and
8055 the strerror, like perror does.
8057 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
8059 * Makefile.in: use gas_target instead of modifying target_cpu.
8060 From Steve Chamberlain:
8061 Makefile.in: Handle m68*-*-coff*.
8062 read.c, read.h: add mult argument to s_space
8064 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8065 Motorola and MIT syntax; gas can now assemble either type of
8067 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8069 m68kcoff.mt: for m68k COFF.
8070 obj-coffbfd.c: (fixup_mdeps) added

8073 (write_object_file) call fixup_mdeps
8074 (fixup_segment) set fx_subsy to 0.
8075 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8077 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8080 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8082 * Makefile.in (LIBS): Include opcode library.

8105 little endian byte order (used to use endianness of host).
8107 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8109 * config/tc-m68k.c (init_table): Now const. Always include 68851
8110 data, so that "bc" is available to 68040 cache instructions.
8111 Added "tt0", "tt1", and 68ec030 variants.
8112 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8113 (enum _register): Added TT0, TT1.
8114 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8115 line number correctly in "internal error" messages. Don't print
8116 architecture-mismatch message for operand errors.
8118 From Colin Smith (colin@wrs.com):
8119 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
8120 than install_operand.

8141 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8142 has already been formatted (but may still contain %-characters).
8145 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8147 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8148 written with indirection on the last two operands, which can be
8149 either data or address registers. Added a new operand type 'r'
8150 which accepts either register type. Added '(' to notend stuff in
8151 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8451 * doc/Makefile.in: commented out line for building as-all.texinfo.
8454 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
8456 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
8458 * Makefile.in: added check target.
8460 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8462 * Makefile.in: added tooldir and program_prefix.
8464 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
8466 * write.{c,h} (fix_new): Make these declarations consistent.
8468 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
8470 * Makefile.in (strerror.o): Add rule so that broken Sun make can
8473 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
8475 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
8477 * expr.c (operand): if can't work out what sort of operand it is,
8478 then look through FLT_CHARS for a hint.
8480 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8482 * Makefile.in, configure.in: removed traces of namesubdir,
8483 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8484 copyrights to '92, changed some from Cygnus to FSF.
8486 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8487 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8488 copyrights to '92, changed some from Cygnus to FSF.
8490 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8492 * expr.c: If an expression is single comma, then return with
8493 SEG_ABSENT rather than an error - since the sparc front end does
8494 really strange things with things like fbge,a
8496 * as.h: include bfd.h if using many sections
8497 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8498 local labels didn't work.
8499 * listing.c (list_symbol_table): don't core dump when there's no
8501 * write.c, write.h: call fix_new with the right number of args on
8503 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8506 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8508 * app.c: MRI compatibility - allow single quote to start a string.
8509 * as.c: fix typo recently introduced.
8510 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8511 * expr.c: Much rewriting, to accomodate MRI syntax for
8512 expressions. Also easier to read now.
8513 * listing.c: Put back defuns
8514 * read.c: modified to accept MRI syntax, put back listing pseudo
8515 ops so that an assembler built with NO_LISTING ignores list ops
8517 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8518 machine is a SPARC or a 29K.
8519 * config/obj-aout.c: added s_sect pseudo op
8520 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8521 fill in the timestamp.
8522 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8523 anymore, define all the relocs which the tc-<x> bit will use so we
8524 can translate from them to the coff types.
8525 * config/tc-a29k.c: reloc_type isn't ane enum any more
8526 * config/tc-m68k.c: Added NO_RELOC definition.
8528 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8530 * Makefile.in: put header files before C source for TAGS; remove
8531 references to non-existent syscalls.h.
8533 * read.c, write.c subsegs.c: back out the .bss changes.
8535 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8537 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8541 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8543 * symbols.c (local_label_name): symbols now start with ^A.
8545 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8546 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8547 generate these sections. .align: will use NOP_OPCODE or 0
8548 for padding. This is just for being nice to the
8551 * expr.c (operand): changed to generate local label "\001L0"
8552 starting with a ^A so that it is recognized as a local label.
8554 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8556 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8557 i/o opcodes - inb, inw, outb and outw. string manipulation with
8558 att syntax - scmp, slod, smov, ssca, ssto.
8560 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8561 to just after .file .
8563 In obj_crawl_symbol_chain() where it tries to put the external
8564 symbols apart, with the condition:
8565 (!S_IS_DEFINED(symbolP) &&
8566 !S_IS_DEBUG(symbolP) &&
8567 !SF_GET_STATICS(symbolP))
8568 it was moving too many symbols out. So I switch it back to the
8570 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8572 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8573 so that we don't use the F_RELFLG which make the linker complain
8574 that somebody has stripped the relocation info.
8576 Also, the AIX ld program require that the relocation table
8577 is sorted by r_vaddr like the standard ATT assembler does.
8579 [he also changed the sizeof(struct ...)'s into the coff
8580 style FOOSZ macros. I'm not sure this is right, but I can't
8581 remember why. xoxorich.]
8583 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8585 * Makefile.in, configure.in, doc: use the doc. Build it, install
8588 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8590 * read.c: white space and comments only.
8592 * configure.in: use the new atof-ns32.c for ns32k.
8594 * write.c: comment change only.
8596 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8597 aren't yet integrated.
8599 * tc-i860.[hc]: blew off the dust. Something must still be done
8600 about conflicting relocation types.
8602 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8605 * tc-i960.c, tc-sparc.c: white space and comments only.
8607 * tc-a29k.h: delete duplicate macro definition.
8609 * new file atof-ns32k.c copied from hack's last unreleased gas.
8611 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8613 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8616 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8617 ChangeLog's prior to this are sketchy at best. I have logs.
8618 They just aren't ChangeLogs.
8625 version-control: never
