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

135 processing if add_symbol is undefined or in expr_section.
136 (resolve_symbol_value, case O_add): For symbol plus
137 constant-valued symbol, convert to O_symbol and re-reduce.

144 (print_expr_1): Fix whitespace before printing X_add_number.
146 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
147 not symbol_new, for symbols holding expression values.
148 * expr.h (make_expr_symbol): Move declaration here.
149 * write.c (fix_new_exp): Handle O_add by creating an
150 expression-valued symbol, and calling fix_new_exp recursively.
151 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
152 undefined symbol and a constant, fold the constant into the fixup,
153 and refer to the undefined symbol directly. Then process the
154 fixup again from scratch.
155 (write_object_file): Before calling adjust_reloc_syms, make a pass
156 through the symbol list trying to resolve values.
158 * write.c (print_fixup): New routine, for debugging.
159 (write_relocs): Call bfd_install_relocation. Deleted various
160 hacks for working around problems with bfd_perform_relocation.

177 * write.c (write_relocs): Add file name and line number to
178 as_fatal calls. Handle bfd_reloc_overflow case specifically when
179 RELOC_EXPANSION_POSSIBLE.
181 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
183 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
184 here. Use them for deciding which PRINTF*LIKE macro definitions
186 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
187 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
188 default definitions matching what we were doing before.
189 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
190 always use the varargs form if not using stdarg. It's safe to
191 always use vfprintf, because libiberty will provide it if the
192 native system doesn't. Also, always make format be const.
193 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

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

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

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

266 * config/tc-mips.c (md_shortopts): Remove E.
267 (md_longopts): Add EB and EL.
268 (md_parse_option): Handle -EB and -EL as separate options, rather
269 than as a single -E option with an argument.
271 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
273 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
274 involving global symbols too.
276 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
278 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
280 * configure.in: Test for remove, not delete. Fix cross-assembler
282 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to

292 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
293 many others): new macros; values obtained from "DSTRECRDS.SDL".
294 * config/obj-vms.h (various): use them.
295 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
296 representation (only enum bitfields can avoid being bitstrings).
297 (bitfield_suffix, setup_basic_type): new routines.
298 (VMS_typedef_parse): use them. Now recognize bitfields of all
299 integral types, not just type `int'. Caveat: the representation
300 used for bitfields still does not work for objects placed in
301 registers, and gcc's optimizer sometimes puts small structs there.
303 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
305 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
307 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
308 (tc_frob_label): define this to call vms_check_for_special_label,
309 and declare the latter.
310 * config/obj-vms.c (vax_g_doubles): declare this file-scope
312 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
313 (vms_check_for_special_label): new routine (tc_frob_label).
314 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
315 and `gcc2_compiled.' labels; they won't reach here any more.
316 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
317 double', use `vax_g_doubles' flag to select type of double.
318 (VMS_write_object_file) [traceback setup]: don't pass symbols
319 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
320 and TBT_Routine_End functions.
322 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
324 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
325 S_GET_VALUE() to avoid many repeated function calls.
326 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
327 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
328 gets requested. [All the HACK_DEC_C_STARTUP code appears to
329 be obsolete; gcc does it automatically for vms target. It's
330 also misnamed, because it is for the "VAX C" run-time library,
331 not the newer "DEC C" one which has much different startup code.]
332 {various}: use `S_SET_xxx(symbol,new_value)' rather than
333 `S_GET_xxx(symbol) = new_value'.

342 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
344 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
346 * expr.c (expr): Don't reduce the difference of two symbols in the
347 same frag if the symbols are not in normal sections.
349 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
350 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
351 (obj_attach_unwind_info): Do not define. Not needed anymore.
352 * config/tc-hppa.c: Delete whitespace at EOL.
353 (struct hppa_fix_struct): Delete fx_unwind field and all references.
354 (fix_new_hppa): Last arg is now a pointer to an int. Do not
355 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
356 fixups, store 32bits of unwind information in the fx_addnumber
358 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
359 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
360 pointer to 32 bits of unwind info.
361 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
362 pointer to the dummy symbol; set the addend field to fx_addnumber.
363 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
364 rather than &bfd_XXX_section.
366 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
368 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
369 value by one; discard adjustments previously being made. From
372 VMS- and Vax-related changes from Pat Rankin:
373 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
374 * vmsconf.sh: no longer have make-gas.com echo text about needing
375 to modify the gcc-vms driver when intending to use with gcc 1.x.
376 * as.c (parse_options): suppress 'v' from std_short_options and
377 eliminate VMS-specific conditional initialization;
378 [default case]: check for '-v' if md_parse_options doesn't recognize

382 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
383 for O_big literal operands (double floats and long long ints);
384 [VMS, md_shortopts]: add second colon after 'v';
385 (md_parse_options) [VMS, case 'v']: check for argument, so
386 caller can handle `-v' w/o arg.

431 Rewrite handling of program_transform_name.
433 * configure.in: Test for functions unlink and delete.

437 Update for autoconf 1.118:
438 * gdbinit.in: New file, created from old .gdbinit.
440 * aclocal.m4 (GAS_GDBINIT): Deleted.
441 * configure.in: Don't use it. Instead, generate .gdbinit from
442 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
443 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
444 to ensure that older versions of autoconf aren't used.

470 PIC implementation for i386-linux, based on code from Eric
471 Youngdale and Paul Kranenburg, with some work of my own:

1759 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,

1875 floating point and binary numbers respectively; if it doesn't
1876 work, treat them as local labels.
1878 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
1879 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
1881 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
1883 * vmsconf.sh: In generated file, get ".obj" suffix right, build
1884 source files from other directories into objects in the current
1885 directory, and specify PSECT attributes explicitly to linker.
1886 Also added missing label.
1887 * Makefile.in (stamp-mk.com): Reference new variable
1888 VMS_OTHER_OBJS for list of non-local object files, instead of

1907 (macro): Likewise. For M_LA_AB permit a difference expression
1908 when generating embedded PIC code between an arbitrary symbol and
1909 a symbol in the .text section.
1910 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
1911 BFD_RELOC_PCREL_LO16 to be emitted.

1951 (hppa_tc_symbol): Likewise.
1953 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
1954 elf_tc_make_sections stuff. It was there to support PA braindamage
1955 which has been fixed, and in the case of elf_tc_make_sections is
1956 redundant with elf_tc_final_processing.

1976 don't spew remainder of input file in error message.
1977 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
1978 message with reloc type and try to process remainder of file.

1986 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
1988 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1990 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
1991 flag rather than signedp field. Only permit extended range if
1992 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
1993 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
1995 * config/tc-ppc.c (ppc_size): New static variable.
1996 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
1997 (md_begin): If an instruction has a size specific flag set, only
1998 add it if we are assembling that size.

2002 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2003 cross section PC relative relocs right for COFF and ELF.
2005 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2007 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
2008 (OBJ_PROCESS_STAB): Don't define.

2012 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2013 the type of symbol set symbols which happen to be in the absolute
2014 or undefined section.

2018 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2019 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),

2030 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2031 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2033 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2034 branch with an instruction that uses $at, in case the branch is
2036 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2037 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2038 to make it pcrel_offset.
2039 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2040 reloc->address; another gruesome hack to get gas reloc handling to
2043 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2045 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2048 (emit_insn): New function.
2049 (md_assemble): Call it.
2050 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2052 (lituse_pending): New variable. Set by anything that generates a
2053 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2054 tested by code that might want to emit a LITUSE reloc.
2055 (emit_unaligned_io): New function. Currently calls md_assemble,
2056 but it should eventually be converted to generate the insn itself
2057 and call emit_insn directly.
2058 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2059 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2060 emit_bis_r): Likewise.
2061 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2062 (alpha_ip, label get_macro): Don't emit the final instruction if
2064 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2065 unaligned memory access macros.
2066 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2067 the value can't be resolved.
2069 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2071 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2072 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2073 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2085 * config/tc-mips.c (enum mips_pic_level): New enum.
2086 (mips_pic): Change from int to enum mips_pic_level. Change all
2087 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2088 (load_address): Handle EMBEDDED_PIC.
2089 (macro): Handle EMBEDDED_PIC in all PIC cases.
2090 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2091 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2092 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2093 works). Do not permit -G with SVR4_PIC.
2094 (s_abicalls): Warn if -G was used, and force -G 0.
2095 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2096 anything but a.out, not just for ELF. For ECOFF, don't generate a
2097 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2099 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2101 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2103 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2104 parameters to avoid losing when compiling with HP CC.
2105 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2107 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2109 * Makefile.in (config-stamp): If `defs' is defined, emit a
2110 preprocessor directive to create a macro named by this value into
2111 config.new; don't explicitly go for BFD_ASSEMBLER.
2112 * configure.in: Define `defs', not `BFDDEF'. Set it to
2113 MANY_SEGMENTS for any obj-coffbfd target.
2114 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2115 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2117 (LOCAL_LOADLIBES): Deleted.
2118 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2119 * config/m88kcoff.mt (TDEFINES): Ditto.
2120 * config/ebmon29k.mt: Deleted.

2123 * config/sparc.mt: Deleted.
2124 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

2145 bfd_set_symtab is called.
2146 (dump_section_relocs): Note whether a symbol is a section symbol
2148 (adjust_reloc_syms): For now, always supply an absolute symbol for
2149 fixups without symbols but not yet `done'. Use section_symbol to
2150 get the symbol, instead of going directly for abs_symbol.
2151 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2152 reloc is not a section symbol and is not in the symbol table.
2153 (set_symtab): New function, broken out from write_object_file.
2154 Counts symbol table instead of relying on an earlier count.
2155 (write_object_file): Call set_symtab, but do it after potentially
2156 invoking the *_frob_file macros. Don't bother counting symbols.
2157 Call symbol_remove, instead of expanding it in place. Moved the
2158 conditionalized `object_file_size' declaration down to
2159 conditionalized block where it's used. When using the absolute
2160 symbol for a fixup without a symbol, set sy_used_in_reloc.
2161 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2162 the correct symbol for the absolute section.
2164 * subsegs.c (section_symbol): Use symbol_new instead of
2165 symbol_make, since we may want it to go into the symbol table.
2166 Make the new symbol have internal linkage. If
2167 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2168 symbol with the newly created GAS symbol.
2169 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2170 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2175 (in_signed_range): New function.
2177 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2178 (sparc_ip, label "immediate"): Reject constants for pcrel
2179 instructions only if the relocation type indicates a "call"
2180 instruction and the offset is within range of a "jmpl %g0". If
2181 it's not in range, use the absolute section symbol plus an offset.
2182 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2184 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2186 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2189 * configure.in: Eliminated all targets using obj-coff but not
2190 defining BFD_ASSEMBLER; I think all such targets that are
2191 supported will be matched by real CPU-OS combinations earlier in
2193 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2194 some comments about the dpx2 configuration, but left it disabled,
2195 since it couldn't be reached before.
2196 (target a29k-amd-ebmonold): Deleted.
2198 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2206 the 'j' operand if there are no further alternatives for this
2209 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2210 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2211 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2213 * config/tc-mips.c (mips_align): Take new argument, label, and use
2214 it instead of global insn_label.
2215 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2216 call to mips_emit_delay and pass it to mips_align.
2218 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2220 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2222 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2223 argument to a .callinfo directive. Don't loop forever on errors.
2225 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2226 use pre-defined registers as arguments.

2231 S_IS_EXTERNAL when deciding whether to discard a symbol.
2233 * config-gas.com: Scan Makefile.in, not version.c, for current
2234 version number. Delete all versions of temp files when finished
2235 with them. Create config.h.
2237 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2238 values to reduce number of lookups with S_GET_VALUE. Skip debug
2239 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2240 holger@botbso.rhein-main.de.)
2241 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2242 field. (Also from Holger Teutsch.) Watch for a would-be register
2243 mask that spans frags.
2245 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2246 this_base, not line_base. (Patch from Andreas Arens,

2249 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2250 look local if they're exported or undefined. Used to be done for
2253 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2254 Get it from the looked-up symbol, instead of using the string from
2255 the input stream, which is no longer null-terminated.
2256 (LEX_PCT): New macro, defaults to 0.
2257 (lex_type): Use it for `%'.
2259 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2260 (vip_op): Now static, and returns void. Callers changed. Added
2262 (vip): Ditto. Call as_fatal directly if a program bug is

2309 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2310 0xffff for 'j' to be compatible with MIPS assembler. These
2311 numbers are actually treated as negative.

2322 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this
2323 work. It still doesn't. It now fails to compile, instead of
2324 silently compiling to do nothing.
2325 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
2327 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

4266 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4267 the table, require that the one without bit 0x1000000 set come
4268 first. Require further that it be case 'b' or 'P'. The a29k
4269 opcode table already meets these constraints.
4270 (machine_ip): When handling case 'i' or 'A', make sure that the
4271 appropriate opcode really exists by looking at the next entry in

4326 * write.c (write_relocs): For relocs that are pc_relative and
4327 pcrel_offset and not partial_inplace, adjust reloc->addend to

4378 OPTIONAL_REGISTER_PREFIX if either is already defined.
4380 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4382 * configure.in: Set bfd_gas for all sparc targets. Added facility
4383 for keeping or rejecting configurations still under development;
4384 default is to assume production environment, and reject configs
4385 still being worked on. Mark Elf configurations (except sparc and
4386 i386) as developmental. Deleted cases matching some generic names
4387 in favor of more specific names. (E.g., when we get Alpha

4405 for functions only used within tc-hppa.c, likewise for structures,
4406 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4407 conditional code in a few small places.
4409 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4410 structures, global variables, forward declarations together.

4412 conditional code -- try to group conditional code together
4413 into a few places. Make all functions and variables which
4414 are only used within tc-hppa.c static. PARAMize all functions.
4415 Add comments to functions. Delete unused functions, variables,
4416 #defines, etc. Delete unused members within structures. Delete
4417 ldil;ble hacks -- it is believed they were installed to work
4418 around old gas bugs. Avoid using mixed case for local
4419 functions, variables, and structures. Fix formatting problems
4420 not found by GNU-indent. Add FIXME notices for things which
4421 should be worked on the near future. Delete lots of old
4422 useless (1.36 PA-SOM) code.
4424 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type

4451 a multiple of the section alignment rather than always a
4454 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4455 bits are zero (eg they specify no relocations), then do not even
4456 bother adding their entries to thesymextn section.

4501 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4503 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4504 ELF, since the ELF object format does not have these type of
4505 relocations. Change the abort into as as_bad and return
4506 BFD_RELOC_NONE to silence compiler warnings.
4507 (md_assemble): Keep track of the instruction size. Allow white
4508 space between the $ and the constant for compatibility with older
4509 gases and other assemblers.
4510 (i386_operand): Skip spaces between $ and expression.

5584 * Extensive changes to permit symbols to contain any expression
5585 type and to delay the computation of the expression until the
5586 value is actually needed. This permits setting symbols to values
5587 calculated based on object code size. Expressions were changed to
5588 no longer be in a section, to stop the overloading of segment and
5589 expression type that previously occurred.

5677 (previous_section, previous_subsection): New vars.
5678 (obj_elf_section): Save current place in case DWARF code wants us
5679 to pop back to it. Handle unquoted section name as well as quoted
5680 section name. Don't crash on invalid strings.
5681 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

5793 sy_resolved and sy_resolving single bit fields.
5794 * symbols.c (symbol_new): Don't initialize sy_forward field.

6942 avoid some redefinition complaints on some systems.

6953 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

6960 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
6962 * Makefile.in: add dvi target; as-$(config).texinfo might live in
6963 srcdir, might be in objdir.

6993 dropping a space immediately following an identifier.

6995 lines; I don't think that can be done portably.
6996 * config/tc-mips.c (macro): Use $AT if target register is zero in
6997 load instruction, which it can be for a floating point load.

7490 * obj-vms.c (final_forward_reference): New function, used to help
7491 resolve the data types of as many struct elements as possible
7492 when some part of the struct is not fully defined by the compiler.
7493 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
7495 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7496 as symbols as well in the object file. Look for external functions
7497 that start with "__vt.", and turn them into variables, since the
7498 g++ compiler is incapable of doing this.
7499 * tc-vax.c: Add '1' option for backward compatibility with older GCC
7501 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
7502 * input-scrub.c (as_where): Fix bug where as would crash if we did not
7503 have the name of the source file yet.

7506 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
7508 * read.c (s_data): Always use "data_section", since it'll map to
7509 SEG_DATA or SEG_E1 if needed.
7510 (s_lcomm): Likewise with bss_section.
7511 (s_fill): Use memset, not bzero.
7513 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

7529 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
7530 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

7534 (section_alignment): Declare only if not BFD_ASSEMBLER.
7535 (big_section, reg_section, pass1_section, diff_section,
7536 absent_section, text_section, data_section, bss_section): If
7537 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7538 mapping to segT enum values.
7539 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7540 if these are used or defined, if BFD_ASSEMBLER.
7541 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7542 subseg_new split into two functions.
7543 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7545 * as.h (volatile): Don't define if already defined.
7546 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7548 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7549 declare with format attribute for -Wformat checking.
7551 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7553 * app.c, config/tc-*.c: Don't include read.h, since it is already
7556 * These are based on patches from Minh Tran-le
7557 <mtranle@paris.intellicorp.com>.
7558 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7559 obj_format coffbfd and gas_target i386coff for target.
7560 (i[34]86-*-isc*): New host (uses sysv).
7561 * config/i386aix.mt: Removed (no longer used).
7562 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7564 (LDFLAGS): Added, defined as -shlib.
7565 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7566 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7567 (DOT_LABEL_PREFIX): Define.
7568 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7569 name rather than L0\001.
7570 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7572 * symbols.c, symbols.h (local_bss_counter): Removed.

7581 (size_section): Restored sanity check.
7582 (do_relocs_for): Base section address on s_paddr rather than
7583 computing it. Adjust a29k R_IHIHALF special case to account for
7584 section paddr (used to require paddr to be zero). If there are no
7585 reclos, set s_relptr to 0. Set relocation size in object_headers.
7586 (fill_section): Always set s_vaddr here, removing
7587 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7588 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7589 Set STYP_INFO for .comment.

7593 H_{SET,GET}_* macros.
7594 (do_linenos_for): Set lineno size in object_headers.
7595 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7596 set s_vaddr here. If string_byte_count remains 4, set it back to
7597 0, and only write strings out if there are some. Call
7598 fill_section before do_relocs_for and do_linenos_for.
7599 (obj_coff_section): Handle optional quoted second argument giving
7600 section characteristics.
7601 (obj_coff_bss): Added to handle .bss.
7602 (obj_coff_ident): Added to handle .ident (puts string in .comment

7608 adjustment (already happened only for common symbols, but this is
7610 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

7622 (do_scrub_next_char): For \", return " not '.
7623 (symbol_chars): Now const.
7625 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7626 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7628 * config/obj-coff.h: Don't use #elif.
7630 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7631 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

7658 using ZERO_BASED_SEGMENTS.
7659 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7660 never set segment address for SEG_E2 (.bss) and don't write out
7661 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7662 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7663 definitions, and don't merge tags with non-tags. Check for .bf
7664 rather than just checking whether the second character is b and
7665 the third character is f.
7666 (obj_coff_val): gcc can generate values which we don't handle
7667 correctly; discard information for now, since it only affects the
7668 debugging information.

7670 (yank_symbols): Don't merge labels.
7671 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7968 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7969 sections starting from zero, rather than making them consecutive.
7970 This makes subsequent reloc calculations easier, esp if the object
7971 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7972 allocate lcomm in .data rather than in .bss. It seems that some
7973 tools can't cope with a non-zero sized bss before linkage.
7975 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7977 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
7978 throughout. That enum no longer means what we thought it meant.

7999 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8001 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8002 .word is < -32768 or > 32767. The -J flag causes the error to be
8003 ignored. This is to catch over-sized switches generated by gcc on
8004 systems which don't support the broken .word hack.
8005 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8006 write.c (fixup_segment): check for signed .word overflow if
8007 WARN_SIGNED_OVERFLOW_WORD.

8036 From Steve Chamberlain:
8037 Makefile.in: Handle m68*-*-coff*.
8038 read.c, read.h: add mult argument to s_space
8040 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8041 Motorola and MIT syntax; gas can now assemble either type of

8051 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8053 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8056 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8058 * Makefile.in (LIBS): Include opcode library.

8085 * config/tc-m68k.c (init_table): Now const. Always include 68851
8086 data, so that "bc" is available to 68040 cache instructions.
8087 Added "tt0", "tt1", and 68ec030 variants.
8088 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8089 (enum _register): Added TT0, TT1.
8090 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8091 line number correctly in "internal error" messages. Don't print
8092 architecture-mismatch message for operand errors.
8094 From Colin Smith (colin@wrs.com):
8095 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

8117 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8118 has already been formatted (but may still contain %-characters).
8121 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8123 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8124 written with indirection on the last two operands, which can be
8125 either data or address registers. Added a new operand type 'r'
8126 which accepts either register type. Added '(' to notend stuff in
8127 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8463 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8464 copyrights to '92, changed some from Cygnus to FSF.
8466 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8468 * expr.c: If an expression is single comma, then return with
8469 SEG_ABSENT rather than an error - since the sparc front end does
8470 really strange things with things like fbge,a
8472 * as.h: include bfd.h if using many sections
8473 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8474 local labels didn't work.
8475 * listing.c (list_symbol_table): don't core dump when there's no
8477 * write.c, write.h: call fix_new with the right number of args on
8479 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8482 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8484 * app.c: MRI compatibility - allow single quote to start a string.
8485 * as.c: fix typo recently introduced.
8486 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8487 * expr.c: Much rewriting, to accomodate MRI syntax for
8488 expressions. Also easier to read now.
8489 * listing.c: Put back defuns
8490 * read.c: modified to accept MRI syntax, put back listing pseudo
8491 ops so that an assembler built with NO_LISTING ignores list ops
8493 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8494 machine is a SPARC or a 29K.
8495 * config/obj-aout.c: added s_sect pseudo op
8496 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8497 fill in the timestamp.
8498 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8499 anymore, define all the relocs which the tc-<x> bit will use so we
8500 can translate from them to the coff types.
8501 * config/tc-a29k.c: reloc_type isn't ane enum any more
8502 * config/tc-m68k.c: Added NO_RELOC definition.
8504 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8506 * Makefile.in: put header files before C source for TAGS; remove
8507 references to non-existent syscalls.h.
8509 * read.c, write.c subsegs.c: back out the .bss changes.
8511 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8513 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8517 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8519 * symbols.c (local_label_name): symbols now start with ^A.
8521 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8522 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8523 generate these sections. .align: will use NOP_OPCODE or 0
8524 for padding. This is just for being nice to the
8527 * expr.c (operand): changed to generate local label "\001L0"
8528 starting with a ^A so that it is recognized as a local label.
8530 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8532 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8533 i/o opcodes - inb, inw, outb and outw. string manipulation with
8534 att syntax - scmp, slod, smov, ssca, ssto.
8536 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8537 to just after .file .
8539 In obj_crawl_symbol_chain() where it tries to put the external
8540 symbols apart, with the condition:
8541 (!S_IS_DEFINED(symbolP) &&
8542 !S_IS_DEBUG(symbolP) &&
8543 !SF_GET_STATICS(symbolP))
8544 it was moving too many symbols out. So I switch it back to the
8546 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8548 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8549 so that we don't use the F_RELFLG which make the linker complain
8550 that somebody has stripped the relocation info.
8552 Also, the AIX ld program require that the relocation table
8553 is sorted by r_vaddr like the standard ATT assembler does.
8555 [he also changed the sizeof(struct ...)'s into the coff
8556 style FOOSZ macros. I'm not sure this is right, but I can't
8557 remember why. xoxorich.]
8559 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8561 * Makefile.in, configure.in, doc: use the doc. Build it, install
8564 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8566 * read.c: white space and comments only.
8568 * configure.in: use the new atof-ns32.c for ns32k.
8570 * write.c: comment change only.
8572 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8573 aren't yet integrated.
8575 * tc-i860.[hc]: blew off the dust. Something must still be done
8576 about conflicting relocation types.
8578 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8581 * tc-i960.c, tc-sparc.c: white space and comments only.
8583 * tc-a29k.h: delete duplicate macro definition.
8585 * new file atof-ns32k.c copied from hack's last unreleased gas.
8587 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8589 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8592 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8593 ChangeLog's prior to this are sketchy at best. I have logs.
8594 They just aren't ChangeLogs.
