14 * config/tc-ppc.c (ppc_fix_adjustable): Resolve symbol values
15 rather than explicitly adding the frag address.
16 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark
17 the end of the line numbers; this replaces the zero entry which
18 used to be added by coff_add_linesym, removed Oct 7.
19 (coff_adjust_section_syms): Ignore sections with no seginfo.
21 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

41 * Makefile.in (comparison): When comparing as.new or gasp.new, try
42 running the binary through sed to avoid differences due to
43 "stage1" or "stage2" having been written into the binary.
45 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
47 ELF symbol size handling, based on code from Eric Youngdale:

80 * config/obj-coff.h (coff_adjust_section_syms, coff_frob_file):
82 (obj_frob_file): New macro.
84 * config/obj-coff.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Renamed from

110 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
112 (diststuff): New target; builds DISTSTUFF.
113 (realclean): Separate target, depend on clean and distclean, then
115 * make-gas.com: Deleted.
117 * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New
118 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF

136 referring to PLT entries.
137 * write.c (fix_new_internal): Initialize fx_plt to zero.
138 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.

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

146 DEBUG5 is defined, print out each fixup before and after
148 (fixup_segment): If DEBUG5 is defined, print out each fixup before
149 and after processing.

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

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

186 Print segment name. Don't call print_expr_1 on an undefined
188 (print_expr_1): Fix whitespace before printing X_add_number.
190 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
191 not symbol_new, for symbols holding expression values.
192 * expr.h (make_expr_symbol): Move declaration here.
193 * write.c (fix_new_exp): Handle O_add by creating an
194 expression-valued symbol, and calling fix_new_exp recursively.
195 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
196 undefined symbol and a constant, fold the constant into the fixup,
197 and refer to the undefined symbol directly. Then process the
198 fixup again from scratch.
199 (write_object_file): Before calling adjust_reloc_syms, make a pass
200 through the symbol list trying to resolve values.
202 * write.c (print_fixup): New routine, for debugging.
203 (write_relocs): Call bfd_install_relocation. Deleted various
204 hacks for working around problems with bfd_perform_relocation.

212 * config/tc-mips.c: Include subsegs.h.
213 (md_apply_fix): If an unconditional b or bal overflows, and we are
214 not assembling PIC code, replace it with a j or jal.
216 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
217 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

221 * write.c (write_relocs): Add file name and line number to
222 as_fatal calls. Handle bfd_reloc_overflow case specifically when
223 RELOC_EXPANSION_POSSIBLE.
225 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
227 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
228 here. Use them for deciding which PRINTF*LIKE macro definitions
230 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
231 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
232 default definitions matching what we were doing before.
233 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
234 always use the varargs form if not using stdarg. It's safe to
235 always use vfprintf, because libiberty will provide it if the
236 native system doesn't. Also, always make format be const.
237 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
239 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

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

270 * config/ho-*.h: Now-unused files deleted.
272 * symbols.c (copy_symbol_attributes): New function. Copies BFD
273 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
274 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
275 zero. Don't call obj_frob_forward_symbol.
276 * read.c (pseudo_set): Call copy_symbol_attributes, but only if

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

284 md_estimate_size_before_relax, md_ri_to_chars,
285 md_create_short_jump, md_create_long_jump.
286 (brtab_emit): Use data_section, not SEG_DATA.
288 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
290 * config/vms-conf.h: new file, manually derived from conf.in.
291 * config-gas.com: use it, and eliminate obsolete "host.h".

300 (ppc_es): Clear ppc_current_block.
301 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
302 from the csect of the enclosing block.
304 * config/tc-mips.c (insns_since_cache_access): Remove.
305 (append_insn): Remove setting of insns_since_cache_access, and
306 special 4600 handling; it turns out not to be required.
308 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
310 * config/tc-mips.c (md_shortopts): Remove E.
311 (md_longopts): Add EB and EL.
312 (md_parse_option): Handle -EB and -EL as separate options, rather
313 than as a single -E option with an argument.
315 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
317 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
318 involving global symbols too.
320 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
322 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
324 * configure.in: Test for remove, not delete. Fix cross-assembler
326 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to

336 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
337 many others): new macros; values obtained from "DSTRECRDS.SDL".
338 * config/obj-vms.h (various): use them.
339 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
340 representation (only enum bitfields can avoid being bitstrings).
341 (bitfield_suffix, setup_basic_type): new routines.
342 (VMS_typedef_parse): use them. Now recognize bitfields of all
343 integral types, not just type `int'. Caveat: the representation
344 used for bitfields still does not work for objects placed in
345 registers, and gcc's optimizer sometimes puts small structs there.
347 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
349 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
351 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
352 (tc_frob_label): define this to call vms_check_for_special_label,
353 and declare the latter.
354 * config/obj-vms.c (vax_g_doubles): declare this file-scope
356 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
357 (vms_check_for_special_label): new routine (tc_frob_label).
358 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
359 and `gcc2_compiled.' labels; they won't reach here any more.
360 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
361 double', use `vax_g_doubles' flag to select type of double.
362 (VMS_write_object_file) [traceback setup]: don't pass symbols
363 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
364 and TBT_Routine_End functions.
366 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
368 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
369 S_GET_VALUE() to avoid many repeated function calls.
370 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
371 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
372 gets requested. [All the HACK_DEC_C_STARTUP code appears to
373 be obsolete; gcc does it automatically for vms target. It's
374 also misnamed, because it is for the "VAX C" run-time library,
375 not the newer "DEC C" one which has much different startup code.]
376 {various}: use `S_SET_xxx(symbol,new_value)' rather than
377 `S_GET_xxx(symbol) = new_value'.
379 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
381 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
382 not &bfd_abs_section.

386 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
388 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
390 * expr.c (expr): Don't reduce the difference of two symbols in the
391 same frag if the symbols are not in normal sections.
393 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
394 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
395 (obj_attach_unwind_info): Do not define. Not needed anymore.
396 * config/tc-hppa.c: Delete whitespace at EOL.
397 (struct hppa_fix_struct): Delete fx_unwind field and all references.
398 (fix_new_hppa): Last arg is now a pointer to an int. Do not
399 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
400 fixups, store 32bits of unwind information in the fx_addnumber
402 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
403 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
404 pointer to 32 bits of unwind info.
405 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
406 pointer to the dummy symbol; set the addend field to fx_addnumber.
407 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
408 rather than &bfd_XXX_section.
410 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
412 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
413 value by one; discard adjustments previously being made. From
416 VMS- and Vax-related changes from Pat Rankin:
417 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
418 * vmsconf.sh: no longer have make-gas.com echo text about needing
419 to modify the gcc-vms driver when intending to use with gcc 1.x.
420 * as.c (parse_options): suppress 'v' from std_short_options and
421 eliminate VMS-specific conditional initialization;
422 [default case]: check for '-v' if md_parse_options doesn't recognize
424 [default case, #if VMS]: check for filename argument when '-v' seen;
426 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
427 for O_big literal operands (double floats and long long ints);
428 [VMS, md_shortopts]: add second colon after 'v';
429 (md_parse_options) [VMS, case 'v']: check for argument, so
430 caller can handle `-v' w/o arg.

1428 arguments when the size is larger than sizeof (valueT), if
1429 TC_CONS_FIX_NEW is prepared to handle the case (as it is on MIPS).
1431 Fri Jun 3 12:50:13 1994 David J. MacKenzie (djm@rtl.cygnus.com)

1481 (control_regs): New pointer.
1482 (m68k_ip): Use control_regs instead of testing CPU every time.

1491 [DIFF_EXPR_OK]: Do conversion to pc-relative for difference, even
1492 if pcrel is already set.
1494 * read.c (potable): Add this_gcc_requires_the_gnu_assembler in all
1495 lower-case, in case we're ignoring case of opcodes in the input

1501 * config/tc-alpha.c (machine): New variable.
1502 (load_insn): New macro.
1503 (load_insn_table): New function.
1504 (md_begin): Call load_insn_table, once for basic instructions and

1555 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1556 for gcc2's predefined types "long double" (same as double, as
1557 per gcc's current state), "long long int", "long long unsigned

1560 "complex float", "complex double", and "complex long double" are
1563 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
1564 of 0, because the latter indicates success rather than failure

1570 allocating new symbol entry and linking it to VMS_Symbol_type_list.
1572 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
1574 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret

1800 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
1802 (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
1803 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
1804 R_DIR16, and R_DIR32 relocs.

1856 with the preceding instruction even if .set nobopt has been seen.
1857 .set nobopt actually controls whether to bring up an instruction
1858 from the branch target, which gas does not currently support.
1860 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1862 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

1923 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
1925 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>

1995 (hppa_tc_symbol): Likewise.
1997 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
1998 elf_tc_make_sections stuff. It was there to support PA braindamage
1999 which has been fixed, and in the case of elf_tc_make_sections is
2000 redundant with elf_tc_final_processing.
2002 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2004 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

2020 don't spew remainder of input file in error message.
2021 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2022 message with reloc type and try to process remainder of file.

2030 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
2032 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2034 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2035 flag rather than signedp field. Only permit extended range if
2036 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2037 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2039 * config/tc-ppc.c (ppc_size): New static variable.
2040 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2041 (md_begin): If an instruction has a size specific flag set, only
2042 add it if we are assembling that size.
2044 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2046 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2047 cross section PC relative relocs right for COFF and ELF.
2049 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2051 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
2052 (OBJ_PROCESS_STAB): Don't define.

2056 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2057 the type of symbol set symbols which happen to be in the absolute
2058 or undefined section.

2062 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2063 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2064 and -many (all architectures).
2066 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2068 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
2069 involving a function symbol which is not a plabel to zero.
2070 (md_apply_fix): Never pass a function symbol to field_adjust.

2074 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2075 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2077 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2078 branch with an instruction that uses $at, in case the branch is
2080 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2081 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2082 to make it pcrel_offset.
2083 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2084 reloc->address; another gruesome hack to get gas reloc handling to
2087 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2089 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2092 (emit_insn): New function.
2093 (md_assemble): Call it.
2094 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2096 (lituse_pending): New variable. Set by anything that generates a
2097 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2098 tested by code that might want to emit a LITUSE reloc.
2099 (emit_unaligned_io): New function. Currently calls md_assemble,
2100 but it should eventually be converted to generate the insn itself
2101 and call emit_insn directly.
2102 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2103 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2104 emit_bis_r): Likewise.
2105 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2106 (alpha_ip, label get_macro): Don't emit the final instruction if
2108 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2109 unaligned memory access macros.
2110 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2111 the value can't be resolved.
2113 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2115 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2116 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2117 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2119 (mips_force_relocation): New function.
2120 (md_apply_fix): Set fixP->fx_done appropriately.
2121 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2129 * config/tc-mips.c (enum mips_pic_level): New enum.
2130 (mips_pic): Change from int to enum mips_pic_level. Change all
2131 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2132 (load_address): Handle EMBEDDED_PIC.
2133 (macro): Handle EMBEDDED_PIC in all PIC cases.
2134 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2135 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2136 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2137 works). Do not permit -G with SVR4_PIC.
2138 (s_abicalls): Warn if -G was used, and force -G 0.
2139 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2140 anything but a.out, not just for ELF. For ECOFF, don't generate a
2141 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2143 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2145 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2147 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2148 parameters to avoid losing when compiling with HP CC.
2149 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2151 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2153 * Makefile.in (config-stamp): If `defs' is defined, emit a
2154 preprocessor directive to create a macro named by this value into
2155 config.new; don't explicitly go for BFD_ASSEMBLER.
2156 * configure.in: Define `defs', not `BFDDEF'. Set it to
2157 MANY_SEGMENTS for any obj-coffbfd target.
2158 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2159 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2161 (LOCAL_LOADLIBES): Deleted.
2162 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2163 * config/m88kcoff.mt (TDEFINES): Ditto.
2164 * config/ebmon29k.mt: Deleted.
2165 * config/h8300hds.mt: Deleted.

2189 bfd_set_symtab is called.
2190 (dump_section_relocs): Note whether a symbol is a section symbol
2192 (adjust_reloc_syms): For now, always supply an absolute symbol for
2193 fixups without symbols but not yet `done'. Use section_symbol to
2194 get the symbol, instead of going directly for abs_symbol.
2195 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2196 reloc is not a section symbol and is not in the symbol table.
2197 (set_symtab): New function, broken out from write_object_file.
2198 Counts symbol table instead of relying on an earlier count.
2199 (write_object_file): Call set_symtab, but do it after potentially
2200 invoking the *_frob_file macros. Don't bother counting symbols.
2201 Call symbol_remove, instead of expanding it in place. Moved the
2202 conditionalized `object_file_size' declaration down to
2203 conditionalized block where it's used. When using the absolute
2204 symbol for a fixup without a symbol, set sy_used_in_reloc.
2205 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2206 the correct symbol for the absolute section.
2208 * subsegs.c (section_symbol): Use symbol_new instead of
2209 symbol_make, since we may want it to go into the symbol table.
2210 Make the new symbol have internal linkage. If
2211 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2212 symbol with the newly created GAS symbol.
2213 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2214 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2219 (in_signed_range): New function.
2221 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2222 (sparc_ip, label "immediate"): Reject constants for pcrel
2223 instructions only if the relocation type indicates a "call"
2224 instruction and the offset is within range of a "jmpl %g0". If
2225 it's not in range, use the absolute section symbol plus an offset.
2226 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2228 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2230 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2233 * configure.in: Eliminated all targets using obj-coff but not
2234 defining BFD_ASSEMBLER; I think all such targets that are
2235 supported will be matched by real CPU-OS combinations earlier in
2237 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2238 some comments about the dpx2 configuration, but left it disabled,
2239 since it couldn't be reached before.
2240 (target a29k-amd-ebmonold): Deleted.
2242 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2250 the 'j' operand if there are no further alternatives for this
2253 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2254 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2255 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2257 * config/tc-mips.c (mips_align): Take new argument, label, and use
2258 it instead of global insn_label.
2259 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2260 call to mips_emit_delay and pass it to mips_align.
2262 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2264 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2266 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2267 argument to a .callinfo directive. Don't loop forever on errors.
2269 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2270 use pre-defined registers as arguments.

2275 S_IS_EXTERNAL when deciding whether to discard a symbol.
2277 * config-gas.com: Scan Makefile.in, not version.c, for current

2282 values to reduce number of lookups with S_GET_VALUE. Skip debug
2283 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2284 holger@botbso.rhein-main.de.)
2285 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2286 field. (Also from Holger Teutsch.) Watch for a would-be register
2287 mask that spans frags.
2289 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2290 this_base, not line_base. (Patch from Andreas Arens,
2291 ari@obelix.av.rwth-aachen.de.)
2293 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2294 look local if they're exported or undefined. Used to be done for
2297 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2298 Get it from the looked-up symbol, instead of using the string from
2299 the input stream, which is no longer null-terminated.
2300 (LEX_PCT): New macro, defaults to 0.
2301 (lex_type): Use it for `%'.
2303 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2304 (vip_op): Now static, and returns void. Callers changed. Added
2306 (vip): Ditto. Call as_fatal directly if a program bug is

3938 Delete dead code. Simplify.
3939 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
3940 applied are in range. Use bfd_put_32 rather than inserting each

4019 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
4020 standard hpux include files to pick up various function decls.
4022 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

4034 so GAS can attach unwind descriptor information to a BFD symbol.
4035 * config/tc-hppa.c (fix_new_hppa): If necessary attach unwind
4036 descriptor information to the BFD symbol.
4037 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

4055 of interest to the linker. ENTRY/EXIT relocations for SOM are
4056 an example of marker relocations.
4057 * write.c (write_relocs): Instead of assuming size of a relocation
4058 is 4 bytes, pick up the size from relocation itself.

4088 pass new argument for i, j and o cases.
4089 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

4172 text, data, and bss segments with new ones.
4173 (create_new_subspace): When not using aliases each subspace has a
4174 section/segment and subsegments are not needed, so set the subsegment

4310 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4311 the table, require that the one without bit 0x1000000 set come
4312 first. Require further that it be case 'b' or 'P'. The a29k
4313 opcode table already meets these constraints.
4314 (machine_ip): When handling case 'i' or 'A', make sure that the

4370 * write.c (write_relocs): For relocs that are pc_relative and
4371 pcrel_offset and not partial_inplace, adjust reloc->addend to

4424 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4426 * configure.in: Set bfd_gas for all sparc targets. Added facility
4427 for keeping or rejecting configurations still under development;
4428 default is to assume production environment, and reject configs
4429 still being worked on. Mark Elf configurations (except sparc and
4430 i386) as developmental. Deleted cases matching some generic names
4431 in favor of more specific names. (E.g., when we get Alpha

4448 through inclusion of tc-hppa.h. Delete all forward declarations
4449 for functions only used within tc-hppa.c, likewise for structures,
4450 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4451 conditional code in a few small places.
4453 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4454 structures, global variables, forward declarations together.

4456 conditional code -- try to group conditional code together
4457 into a few places. Make all functions and variables which
4458 are only used within tc-hppa.c static. PARAMize all functions.
4459 Add comments to functions. Delete unused functions, variables,
4460 #defines, etc. Delete unused members within structures. Delete
4461 ldil;ble hacks -- it is believed they were installed to work
4462 around old gas bugs. Avoid using mixed case for local
4463 functions, variables, and structures. Fix formatting problems
4464 not found by GNU-indent. Add FIXME notices for things which
4465 should be worked on the near future. Delete lots of old
4466 useless (1.36 PA-SOM) code.
4468 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
4469 field of the fixS structure. Needed to build unwind

4495 a multiple of the section alignment rather than always a
4498 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4499 bits are zero (eg they specify no relocations), then do not even
4500 bother adding their entries to thesymextn section.

4545 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4547 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4548 ELF, since the ELF object format does not have these type of
4549 relocations. Change the abort into as as_bad and return
4550 BFD_RELOC_NONE to silence compiler warnings.
4551 (md_assemble): Keep track of the instruction size. Allow white
4552 space between the $ and the constant for compatibility with older
4553 gases and other assemblers.

5577 * expr.c (expr): Don't let absolute_section override
5578 undefined_section for the return value.
5580 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
5581 pseudo-op with a poc_handler field of NULL, ignore it and treat it
5582 as an instruction instead.
5583 * config/tc-m88k.c (md_pseudo_table): Add "set" with a NULL
5586 * config/tc-h8500.c (md_begin): Use a local variable when
5587 initializing md_relax_table to avoid warnings about modifying a

5598 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
5599 case to set obj_format=elf. Must go before i386-*-sysv* case that
5600 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
5601 *-*-solaris case, and move to before *-sysv* case that wants to
5602 set obj_format to coff.
5603 * config/tc-i386.c (i386_operand): Change all 'exp.X_op' to
5605 * config/tc-i386.c (md_apply_fix): Fix valp to be 'valueT *' for

5628 * Extensive changes to permit symbols to contain any expression
5629 type and to delay the computation of the expression until the
5630 value is actually needed. This permits setting symbols to values
5631 calculated based on object code size. Expressions were changed to
5632 no longer be in a section, to stop the overloading of segment and
5633 expression type that previously occurred.
5635 * as.c (big_section, pass1_section, diff_section, absent_section):
5637 (expr_section): Added (used for dummy symbols which hold

5721 (previous_section, previous_subsection): New vars.
5722 (obj_elf_section): Save current place in case DWARF code wants us
5723 to pop back to it. Handle unquoted section name as well as quoted
5724 section name. Don't crash on invalid strings.
5725 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
5728 * config/obj-elf.h: Don't include struc-symbol.h.

5837 sy_resolved and sy_resolving single bit fields.
5838 * symbols.c (symbol_new): Don't initialize sy_forward field.

7039 lines; I don't think that can be done portably.
7040 * config/tc-mips.c (macro): Use $AT if target register is zero in
7041 load instruction, which it can be for a floating point load.

7115 prototypes for all static functions. Moved existing minimal
7116 debugging format support info #ifndef OBJ_ECOFF blocks.

7165 * make-gas.com: Find obstack.obj if it's not in the current
7167 * read.c (s_ignore): Don't declare is_end_of_line. It's
7168 redundant, and triggers a VMS gcc compiler bug.
7170 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7171 current segment as an argument. (Ignored in all cases but VMS.)
7172 All callers and definitions changed.

7196 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7199 * configure.in: mips-bsd configuration was missing format spec.
7202 * Makefile.in (Makefile): Depends on configure.in.
7204 * config/tc-mips.c (append_insn): Don't check for alignment of
7205 frag in memory; alignment of instructions in section is a separate

7225 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7226 constants are accepted, but symbolic values are not. GCC will not
7227 generate the latter currently.
7229 * frags.c (frag_init): New function.
7230 (zero_address_frag, bss_address_frag): Now initialized at run
7232 * as.c (main): Call frag_init.

7487 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
7489 * configure.in: recognise all sparclite variants
7491 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
7493 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
7494 accidentally changed to use subseg_change where it should have
7497 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
7499 * expr.c (operand): If character other than comma or newline is a
7500 logical end-of-line character, use the newline case.
7501 From Eric Youngdale:
7502 (operand): Set X_add_number field for floating-point numbers.
7503 (operand): Treat zero byte as end-of-operand.
7505 * configure.in (per-target): Look for with_bfd_assembler option.
7506 For now, only accept "no", until the merge is done.
7508 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7509 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7510 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7511 * read.c: Finish conversion to S_* macros in the VMS only
7512 parts of the program. Add "const" modifier to hex_value.
7513 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7515 * expr.c: Add "const" modifier to hex_value.
7516 * symbols.c: Finish conversion to S_* macros in the VMS only
7517 parts of the program. Add "const" modifier to
7518 md_[long,short]_jump_size. Remove declaration of const_flag
7519 (which will be declared in obj-vms.h).
7520 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7521 Fix arguments to VMS_write_object_file.
7522 * config-gas.com: New file. Script for VMS systems to set up the
7523 configuration to build gas for VMS, and create config.status.
7524 * make-gas.com: Redone to work with new scheme.
7525 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
7527 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
7528 will swap bytes if needed on a big endian system. Use throughout
7530 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7531 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7532 types of malformed stabs. Change parsing algorithm so that we are
7533 more certain of having all of the information that we need on hand.
7534 * obj-vms.c (final_forward_reference): New function, used to help
7535 resolve the data types of as many struct elements as possible
7536 when some part of the struct is not fully defined by the compiler.
7537 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
7539 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7540 as symbols as well in the object file. Look for external functions
7541 that start with "__vt.", and turn them into variables, since the
7542 g++ compiler is incapable of doing this.
7543 * tc-vax.c: Add '1' option for backward compatibility with older GCC
7545 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
7546 * input-scrub.c (as_where): Fix bug where as would crash if we did not
7547 have the name of the source file yet.
7548 * config/ho-vms.h: define HO_VMS, not HO_VAX.
7550 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
7552 * read.c (s_data): Always use "data_section", since it'll map to
7553 SEG_DATA or SEG_E1 if needed.
7554 (s_lcomm): Likewise with bss_section.
7555 (s_fill): Use memset, not bzero.
7557 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
7559 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

7573 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
7574 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

7578 (section_alignment): Declare only if not BFD_ASSEMBLER.
7579 (big_section, reg_section, pass1_section, diff_section,
7580 absent_section, text_section, data_section, bss_section): If
7581 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7582 mapping to segT enum values.
7583 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7584 if these are used or defined, if BFD_ASSEMBLER.
7585 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7586 subseg_new split into two functions.
7587 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7589 * as.h (volatile): Don't define if already defined.
7590 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7592 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7593 declare with format attribute for -Wformat checking.
7595 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7597 * app.c, config/tc-*.c: Don't include read.h, since it is already
7600 * These are based on patches from Minh Tran-le
7601 <mtranle@paris.intellicorp.com>.
7602 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7603 obj_format coffbfd and gas_target i386coff for target.
7604 (i[34]86-*-isc*): New host (uses sysv).
7605 * config/i386aix.mt: Removed (no longer used).
7606 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7608 (LDFLAGS): Added, defined as -shlib.
7609 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7610 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7611 (DOT_LABEL_PREFIX): Define.
7612 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7613 name rather than L0\001.
7614 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7616 * symbols.c, symbols.h (local_bss_counter): Removed.
7617 * write.c (write_object_file): bss no longer uses
7618 local_bss_counter. Pass correct data and bss size to
7619 VMS_write_object_file.

7625 (size_section): Restored sanity check.
7626 (do_relocs_for): Base section address on s_paddr rather than
7627 computing it. Adjust a29k R_IHIHALF special case to account for
7628 section paddr (used to require paddr to be zero). If there are no
7629 reclos, set s_relptr to 0. Set relocation size in object_headers.
7630 (fill_section): Always set s_vaddr here, removing
7631 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7632 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7633 Set STYP_INFO for .comment.
7634 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7635 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7637 H_{SET,GET}_* macros.
7638 (do_linenos_for): Set lineno size in object_headers.
7639 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7640 set s_vaddr here. If string_byte_count remains 4, set it back to
7641 0, and only write strings out if there are some. Call
7642 fill_section before do_relocs_for and do_linenos_for.
7643 (obj_coff_section): Handle optional quoted second argument giving
7644 section characteristics.
7645 (obj_coff_bss): Added to handle .bss.
7646 (obj_coff_ident): Added to handle .ident (puts string in .comment

7649 (fixup_mdeps): Change to segment. Call frag_wane after
7651 (fixup_segment): Explicitly check S_IS_COMMON before making 386
7652 adjustment (already happened only for common symbols, but this is
7654 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
7655 * config/tc-i386.c (s_bss): Don't use if I386COFF.

7666 (do_scrub_next_char): For \", return " not '.
7667 (symbol_chars): Now const.
7669 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7670 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7672 * config/obj-coff.h: Don't use #elif.
7674 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7675 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

7701 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7702 using ZERO_BASED_SEGMENTS.
7703 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7704 never set segment address for SEG_E2 (.bss) and don't write out
7705 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7706 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7707 definitions, and don't merge tags with non-tags. Check for .bf
7708 rather than just checking whether the second character is b and
7709 the third character is f.
7710 (obj_coff_val): gcc can generate values which we don't handle
7711 correctly; discard information for now, since it only affects the
7712 debugging information.

7714 (yank_symbols): Don't merge labels.
7715 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7958 support for C source listings. (obj_coff_endef): look in the right
7959 part of the symbol for the symbol name
7961 * tc-m68k.c (get_num): make it work for all segments, not just the
7964 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
7966 * configure.in: recognize i386-*-bsd emulation.

7975 * tc-z8k.c: lots of bug fixes
7977 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7979 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7980 #elif, since it is not supported by old compilers.
7981 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7982 couple of expressions in tc-m68k.c.
7984 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7986 * read.c (cons): If NO_RELOC is defined, use it.
7988 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
7990 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
7992 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
7993 local labels to start with a .) and set REGISTER_PREFIX to %.
7994 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
7996 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

8010 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8012 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8013 sections starting from zero, rather than making them consecutive.
8014 This makes subsequent reloc calculations easier, esp if the object
8015 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8016 allocate lcomm in .data rather than in .bss. It seems that some
8017 tools can't cope with a non-zero sized bss before linkage.
8019 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8021 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

8025 "-mno-688[58]1" options.
8027 * tc-m68k.c: Added CPU32 support.

8040 * Makefile.in (install): if $(tooldir) exists, install as in
8043 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8045 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8046 .word is < -32768 or > 32767. The -J flag causes the error to be
8047 ignored. This is to catch over-sized switches generated by gcc on
8048 systems which don't support the broken .word hack.
8049 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8050 write.c (fixup_segment): check for signed .word overflow if
8051 WARN_SIGNED_OVERFLOW_WORD.
8053 * write.c (fixup_segment): fixed missing parens in expression
8054 checking for byte or word overflow.

8068 * tc-i386.h : new coff defines
8070 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8072 * input-scrub.c (input_scrub_push): call input_file_begin, not
8074 messages.c (as_perror): print ": " between the passed in error and
8075 the strerror, like perror does.
8077 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

8080 From Steve Chamberlain:
8081 Makefile.in: Handle m68*-*-coff*.
8082 read.c, read.h: add mult argument to s_space
8084 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8085 Motorola and MIT syntax; gas can now assemble either type of
8087 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8093 (write_object_file) call fixup_mdeps
8094 (fixup_segment) set fx_subsy to 0.
8095 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8097 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8100 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8102 * Makefile.in (LIBS): Include opcode library.

8127 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8129 * config/tc-m68k.c (init_table): Now const. Always include 68851
8130 data, so that "bc" is available to 68040 cache instructions.
8131 Added "tt0", "tt1", and 68ec030 variants.
8132 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8133 (enum _register): Added TT0, TT1.
8134 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8135 line number correctly in "internal error" messages. Don't print
8136 architecture-mismatch message for operand errors.
8138 From Colin Smith (colin@wrs.com):
8139 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

8161 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8162 has already been formatted (but may still contain %-characters).
8165 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8167 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8168 written with indirection on the last two operands, which can be
8169 either data or address registers. Added a new operand type 'r'
8170 which accepts either register type. Added '(' to notend stuff in
8171 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8449 * flonum-const.c: renamed flonum-konst.c to stop dos name
8452 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
8454 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
8455 tc-m68k.h to te-sun3.h.
8457 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
8459 * configure.in: vxworks68 gets te-sun3.h.
8461 * expr.c: remove limitation that local_labels_dollar or
8462 local_labels_fb must be < 10.
8464 * symbols.c: remove local_labels_dollar, replace with a function
8465 interface for a sparse array. All users adjusted.
8467 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
8469 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8471 * doc/Makefile.in: commented out line for building as-all.texinfo.
8474 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
8476 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
8478 * Makefile.in: added check target.
8480 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8482 * Makefile.in: added tooldir and program_prefix.
8484 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
8486 * write.{c,h} (fix_new): Make these declarations consistent.
8488 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
8490 * Makefile.in (strerror.o): Add rule so that broken Sun make can
8493 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
8495 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
8497 * expr.c (operand): if can't work out what sort of operand it is,
8498 then look through FLT_CHARS for a hint.
8500 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8502 * Makefile.in, configure.in: removed traces of namesubdir,
8503 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8504 copyrights to '92, changed some from Cygnus to FSF.
8506 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8507 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8508 copyrights to '92, changed some from Cygnus to FSF.
8510 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8512 * expr.c: If an expression is single comma, then return with
8513 SEG_ABSENT rather than an error - since the sparc front end does
8514 really strange things with things like fbge,a
8516 * as.h: include bfd.h if using many sections
8517 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8518 local labels didn't work.
8519 * listing.c (list_symbol_table): don't core dump when there's no
8521 * write.c, write.h: call fix_new with the right number of args on
8523 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8526 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8528 * app.c: MRI compatibility - allow single quote to start a string.
8529 * as.c: fix typo recently introduced.
8530 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8531 * expr.c: Much rewriting, to accomodate MRI syntax for
8532 expressions. Also easier to read now.
8533 * listing.c: Put back defuns
8534 * read.c: modified to accept MRI syntax, put back listing pseudo
8535 ops so that an assembler built with NO_LISTING ignores list ops
8537 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8538 machine is a SPARC or a 29K.
8539 * config/obj-aout.c: added s_sect pseudo op
8540 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8541 fill in the timestamp.
8542 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8543 anymore, define all the relocs which the tc-<x> bit will use so we
8544 can translate from them to the coff types.
8545 * config/tc-a29k.c: reloc_type isn't ane enum any more
8546 * config/tc-m68k.c: Added NO_RELOC definition.
8548 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8550 * Makefile.in: put header files before C source for TAGS; remove
8551 references to non-existent syscalls.h.
8553 * read.c, write.c subsegs.c: back out the .bss changes.
8555 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8557 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8561 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8563 * symbols.c (local_label_name): symbols now start with ^A.
8565 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8566 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8567 generate these sections. .align: will use NOP_OPCODE or 0
8568 for padding. This is just for being nice to the
8571 * expr.c (operand): changed to generate local label "\001L0"
8572 starting with a ^A so that it is recognized as a local label.
8574 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8576 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8577 i/o opcodes - inb, inw, outb and outw. string manipulation with
8578 att syntax - scmp, slod, smov, ssca, ssto.
8580 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8581 to just after .file .
8583 In obj_crawl_symbol_chain() where it tries to put the external
8584 symbols apart, with the condition:
8585 (!S_IS_DEFINED(symbolP) &&
8586 !S_IS_DEBUG(symbolP) &&
8587 !SF_GET_STATICS(symbolP))
8588 it was moving too many symbols out. So I switch it back to the
8590 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8592 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8593 so that we don't use the F_RELFLG which make the linker complain
8594 that somebody has stripped the relocation info.
8596 Also, the AIX ld program require that the relocation table
8597 is sorted by r_vaddr like the standard ATT assembler does.
8599 [he also changed the sizeof(struct ...)'s into the coff
8600 style FOOSZ macros. I'm not sure this is right, but I can't
8601 remember why. xoxorich.]
8603 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8605 * Makefile.in, configure.in, doc: use the doc. Build it, install
8608 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8610 * read.c: white space and comments only.
8612 * configure.in: use the new atof-ns32.c for ns32k.
8614 * write.c: comment change only.
8616 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8617 aren't yet integrated.
8619 * tc-i860.[hc]: blew off the dust. Something must still be done
8620 about conflicting relocation types.
8622 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8625 * tc-i960.c, tc-sparc.c: white space and comments only.
8627 * tc-a29k.h: delete duplicate macro definition.
8629 * new file atof-ns32k.c copied from hack's last unreleased gas.
8631 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8633 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8636 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8637 ChangeLog's prior to this are sketchy at best. I have logs.
8638 They just aren't ChangeLogs.
8645 version-control: never
