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

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

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

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

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

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

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

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

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

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

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

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

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

1426 * config/obj-vms.c: Replaced unchecked uses of malloc with
1429 * listing.c (list_symbol_table): Only test BFD64, not
1432 * config/obj-coff.c (fixup_segment) [BFD_ASSEMBLER]
1433 [DIFF_EXPR_OK]: Don't check pcrel, just convert it.
1435 * config/obj-vms.c: Removed lots of extra semicolons after
1436 compound statements.
1437 (strchr): Don't declare here.
1439 * config/ho-vax.h (realloc): Declare.
1441 * config/ho-vms.h (strchr, strdup): Declare.

1449 new VMS symbol-type macros; signed and unsigned quadword integers,
1450 for `long long' support. Their values come from the existing
1451 DSC$K_DTYPE_QU and DSC$K_DTYPE_Q macros in <descrip.h>. The
1452 VMS debugger now recognizes `long long' variables correctly.
1453 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1454 for gcc2's predefined types "long double" (same as double, as
1455 per gcc's current state), "long long int", "long long unsigned
1456 int", and final `otherwise' case (to avoid uninitialized type
1457 and size fields). [caveat: predefined types "complex int",
1458 "complex float", "complex double", and "complex long double" are
1461 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
1462 of 0, because the latter indicates success rather than failure
1463 when passed to `exit' or return from `main' compiled by gcc2.
1465 * config/obj-vms.c (array_suffix, generate_suffix): replace two
1466 hardcoded `0xa3's with macro DBG_S_C_ADVANCED_TYPE from obj-vms.h.
1467 (VMS_typedef_parse): eliminate redundant if-then-else when
1468 allocating new symbol entry and linking it to VMS_Symbol_type_list.
1470 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
1472 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret
1473 the contents of the GAS_VERSION string when falling back to it for
1474 language processor identification.
1476 * make-gas.com, vmsconf.sh (ENVIRON): fix misspelling of
1477 `psect_attr' in linker options.

1897 which has been fixed, and in the case of elf_tc_make_sections is
1898 redundant with elf_tc_final_processing.

1917 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
1918 don't spew remainder of input file in error message.
1919 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
1920 message with reloc type and try to process remainder of file.

1932 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
1933 flag rather than signedp field. Only permit extended range if
1934 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
1935 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
1937 * config/tc-ppc.c (ppc_size): New static variable.
1938 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
1939 (md_begin): If an instruction has a size specific flag set, only
1940 add it if we are assembling that size.

1944 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
1945 cross section PC relative relocs right for COFF and ELF.
1947 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

1972 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
1973 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
1975 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
1976 branch with an instruction that uses $at, in case the branch is
1978 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
1979 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
1980 to make it pcrel_offset.
1981 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to

1991 (md_assemble): Call it.
1992 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
1994 (lituse_pending): New variable. Set by anything that generates a
1995 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
1996 tested by code that might want to emit a LITUSE reloc.
1997 (emit_unaligned_io): New function. Currently calls md_assemble,
1998 but it should eventually be converted to generate the insn itself
1999 and call emit_insn directly.
2000 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2001 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2002 emit_bis_r): Likewise.

2004 (alpha_ip, label get_macro): Don't emit the final instruction if
2006 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2007 unaligned memory access macros.

2013 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2014 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2015 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2030 (load_address): Handle EMBEDDED_PIC.
2031 (macro): Handle EMBEDDED_PIC in all PIC cases.
2032 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2033 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2034 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2035 works). Do not permit -G with SVR4_PIC.
2036 (s_abicalls): Warn if -G was used, and force -G 0.
2037 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2038 anything but a.out, not just for ELF. For ECOFF, don't generate a
2039 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2041 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.

2046 parameters to avoid losing when compiling with HP CC.
2047 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2049 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2051 * Makefile.in (config-stamp): If `defs' is defined, emit a
2052 preprocessor directive to create a macro named by this value into
2053 config.new; don't explicitly go for BFD_ASSEMBLER.
2054 * configure.in: Define `defs', not `BFDDEF'. Set it to
2055 MANY_SEGMENTS for any obj-coffbfd target.
2056 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2057 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,

2087 bfd_set_symtab is called.
2088 (dump_section_relocs): Note whether a symbol is a section symbol
2090 (adjust_reloc_syms): For now, always supply an absolute symbol for
2091 fixups without symbols but not yet `done'. Use section_symbol to
2092 get the symbol, instead of going directly for abs_symbol.
2093 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2094 reloc is not a section symbol and is not in the symbol table.
2095 (set_symtab): New function, broken out from write_object_file.
2096 Counts symbol table instead of relying on an earlier count.
2097 (write_object_file): Call set_symtab, but do it after potentially
2098 invoking the *_frob_file macros. Don't bother counting symbols.
2099 Call symbol_remove, instead of expanding it in place. Moved the
2100 conditionalized `object_file_size' declaration down to
2101 conditionalized block where it's used. When using the absolute
2102 symbol for a fixup without a symbol, set sy_used_in_reloc.
2103 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2104 the correct symbol for the absolute section.
2106 * subsegs.c (section_symbol): Use symbol_new instead of
2107 symbol_make, since we may want it to go into the symbol table.
2108 Make the new symbol have internal linkage. If
2109 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2110 symbol with the newly created GAS symbol.
2111 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2112 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2117 (in_signed_range): New function.
2119 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2120 (sparc_ip, label "immediate"): Reject constants for pcrel
2121 instructions only if the relocation type indicates a "call"
2122 instruction and the offset is within range of a "jmpl %g0". If
2123 it's not in range, use the absolute section symbol plus an offset.
2124 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2126 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2128 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2131 * configure.in: Eliminated all targets using obj-coff but not
2132 defining BFD_ASSEMBLER; I think all such targets that are
2133 supported will be matched by real CPU-OS combinations earlier in
2135 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2136 some comments about the dpx2 configuration, but left it disabled,
2137 since it couldn't be reached before.
2138 (target a29k-amd-ebmonold): Deleted.
2140 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2148 the 'j' operand if there are no further alternatives for this
2151 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2152 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2153 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2155 * config/tc-mips.c (mips_align): Take new argument, label, and use
2156 it instead of global insn_label.
2157 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2158 call to mips_emit_delay and pass it to mips_align.
2160 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2162 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2164 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2165 argument to a .callinfo directive. Don't loop forever on errors.

2173 S_IS_EXTERNAL when deciding whether to discard a symbol.
2175 * config-gas.com: Scan Makefile.in, not version.c, for current

2180 values to reduce number of lookups with S_GET_VALUE. Skip debug
2181 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2182 holger@botbso.rhein-main.de.)
2183 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2184 field. (Also from Holger Teutsch.) Watch for a would-be register
2185 mask that spans frags.
2187 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2188 this_base, not line_base. (Patch from Andreas Arens,
2189 ari@obelix.av.rwth-aachen.de.)
2191 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2192 look local if they're exported or undefined. Used to be done for
2195 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2196 Get it from the looked-up symbol, instead of using the string from
2197 the input stream, which is no longer null-terminated.
2198 (LEX_PCT): New macro, defaults to 0.
2199 (lex_type): Use it for `%'.
2201 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2251 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2252 0xffff for 'j' to be compatible with MIPS assembler. These

2840 still needs to be applied. Set fx_done and clear fx_addsy both,
2841 for now. If TC_HANDLES_FX_DONE isn't defined, assume md_apply_fix

2865 somehow. Rename "punt_it" label to "punt_it_if_unused" to reflect
2867 (EMIT_SECTION_SYMBOLS): Default to 1.
2868 (adjust_reloc_syms): Don't create a new symbol for an absolute

3837 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
3838 applied are in range. Use bfd_put_32 rather than inserting each

3953 of interest to the linker. ENTRY/EXIT relocations for SOM are
3954 an example of marker relocations.
3955 * write.c (write_relocs): Instead of assuming size of a relocation
3956 is 4 bytes, pick up the size from relocation itself.

4326 default is to assume production environment, and reject configs
4327 still being worked on. Mark Elf configurations (except sparc and
4328 i386) as developmental. Deleted cases matching some generic names
4329 in favor of more specific names. (E.g., when we get Alpha

4355 into a few places. Make all functions and variables which
4356 are only used within tc-hppa.c static. PARAMize all functions.
4357 Add comments to functions. Delete unused functions, variables,
4358 #defines, etc. Delete unused members within structures. Delete
4359 ldil;ble hacks -- it is believed they were installed to work
4360 around old gas bugs. Avoid using mixed case for local
4361 functions, variables, and structures. Fix formatting problems
4362 not found by GNU-indent. Add FIXME notices for things which
4363 should be worked on the near future. Delete lots of old
4364 useless (1.36 PA-SOM) code.

4443 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4445 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4446 ELF, since the ELF object format does not have these type of
4447 relocations. Change the abort into as as_bad and return
4448 BFD_RELOC_NONE to silence compiler warnings.
4449 (md_assemble): Keep track of the instruction size. Allow white
4450 space between the $ and the constant for compatibility with older
4451 gases and other assemblers.

6895 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

6935 dropping a space immediately following an identifier.

6938 * config/tc-mips.c (macro): Use $AT if target register is zero in

7013 prototypes for all static functions. Moved existing minimal
7014 debugging format support info #ifndef OBJ_ECOFF blocks.

7063 * make-gas.com: Find obstack.obj if it's not in the current
7065 * read.c (s_ignore): Don't declare is_end_of_line. It's
7066 redundant, and triggers a VMS gcc compiler bug.
7068 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7069 current segment as an argument. (Ignored in all cases but VMS.)
7070 All callers and definitions changed.

7094 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7097 * configure.in: mips-bsd configuration was missing format spec.
7100 * Makefile.in (Makefile): Depends on configure.in.
7102 * config/tc-mips.c (append_insn): Don't check for alignment of
7103 frag in memory; alignment of instructions in section is a separate

7123 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7124 constants are accepted, but symbolic values are not. GCC will not
7125 generate the latter currently.
7127 * frags.c (frag_init): New function.
7128 (zero_address_frag, bss_address_frag): Now initialized at run
7130 * as.c (main): Call frag_init.

7401 (operand): Treat zero byte as end-of-operand.
7403 * configure.in (per-target): Look for with_bfd_assembler option.
7404 For now, only accept "no", until the merge is done.
7406 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7407 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7408 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7409 * read.c: Finish conversion to S_* macros in the VMS only
7410 parts of the program. Add "const" modifier to hex_value.
7411 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7413 * expr.c: Add "const" modifier to hex_value.
7414 * symbols.c: Finish conversion to S_* macros in the VMS only
7415 parts of the program. Add "const" modifier to
7416 md_[long,short]_jump_size. Remove declaration of const_flag
7417 (which will be declared in obj-vms.h).
7418 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7419 Fix arguments to VMS_write_object_file.
7420 * config-gas.com: New file. Script for VMS systems to set up the
7421 configuration to build gas for VMS, and create config.status.

7429 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7430 types of malformed stabs. Change parsing algorithm so that we are
7431 more certain of having all of the information that we need on hand.
7432 * obj-vms.c (final_forward_reference): New function, used to help
7433 resolve the data types of as many struct elements as possible
7434 when some part of the struct is not fully defined by the compiler.

7437 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7438 as symbols as well in the object file. Look for external functions

7474 otherwise, use seg_name array.
7475 (seg_name): Declare only if not BFD_ASSEMBLER.
7476 (section_alignment): Declare only if not BFD_ASSEMBLER.
7477 (big_section, reg_section, pass1_section, diff_section,
7478 absent_section, text_section, data_section, bss_section): If
7479 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7480 mapping to segT enum values.
7481 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7482 if these are used or defined, if BFD_ASSEMBLER.
7483 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7484 subseg_new split into two functions.

7487 * as.h (volatile): Don't define if already defined.
7488 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7490 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7491 declare with format attribute for -Wformat checking.
7493 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7495 * app.c, config/tc-*.c: Don't include read.h, since it is already
7498 * These are based on patches from Minh Tran-le
7499 <mtranle@paris.intellicorp.com>.
7500 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7501 obj_format coffbfd and gas_target i386coff for target.
7502 (i[34]86-*-isc*): New host (uses sysv).
7503 * config/i386aix.mt: Removed (no longer used).
7504 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7506 (LDFLAGS): Added, defined as -shlib.
7507 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7508 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7509 (DOT_LABEL_PREFIX): Define.
7510 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7511 name rather than L0\001.
7512 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7514 * symbols.c, symbols.h (local_bss_counter): Removed.
7515 * write.c (write_object_file): bss no longer uses
7516 local_bss_counter. Pass correct data and bss size to
7517 VMS_write_object_file.
7518 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
7519 argument, rather than using local_bss_counter.

7521 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
7522 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
7523 (size_section): Restored sanity check.
7524 (do_relocs_for): Base section address on s_paddr rather than
7525 computing it. Adjust a29k R_IHIHALF special case to account for
7526 section paddr (used to require paddr to be zero). If there are no
7527 reclos, set s_relptr to 0. Set relocation size in object_headers.
7528 (fill_section): Always set s_vaddr here, removing
7529 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7530 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7531 Set STYP_INFO for .comment.
7532 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7533 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7535 H_{SET,GET}_* macros.
7536 (do_linenos_for): Set lineno size in object_headers.
7537 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7538 set s_vaddr here. If string_byte_count remains 4, set it back to
7539 0, and only write strings out if there are some. Call
7540 fill_section before do_relocs_for and do_linenos_for.
7541 (obj_coff_section): Handle optional quoted second argument giving
7542 section characteristics.
7543 (obj_coff_bss): Added to handle .bss.
7544 (obj_coff_ident): Added to handle .ident (puts string in .comment
7546 (obj_coff_lcomm): Put common symbols in .bss, not .data.
7547 (fixup_mdeps): Change to segment. Call frag_wane after
7549 (fixup_segment): Explicitly check S_IS_COMMON before making 386
7550 adjustment (already happened only for common symbols, but this is
7552 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

7563 * app.c (app_push): Use memcpy, not bcopy.
7564 (do_scrub_next_char): For \", return " not '.
7565 (symbol_chars): Now const.
7567 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7568 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7570 * config/obj-coff.h: Don't use #elif.
7572 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7573 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
7575 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

7599 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7600 using ZERO_BASED_SEGMENTS.
7601 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7602 never set segment address for SEG_E2 (.bss) and don't write out
7603 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7604 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7605 definitions, and don't merge tags with non-tags. Check for .bf
7606 rather than just checking whether the second character is b and
7607 the third character is f.
7608 (obj_coff_val): gcc can generate values which we don't handle
7609 correctly; discard information for now, since it only affects the
7610 debugging information.
7611 (tag_find_or_name): Don't insert tags in the symbol table.
7612 (yank_symbols): Don't merge labels.
7613 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7616 (obj_coff_section): Accept and ignore a trailing quoted string, as
7617 used in AT&T i386 syntax.
7618 (fixup_segment): Take segment as argument. On the i386, adjust PC
7619 relative addends by the segment vaddr.
7620 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
7621 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

7668 options. Updated options documentation for m68k. Some minor
7669 wording/punctuation changes.

7758 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
7759 could be doing emulation.
7761 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7764 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
7767 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
7769 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

7793 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7795 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
7796 constant will not fit in an immediate field.
7797 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
7799 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

7832 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
7834 * Support for i386-sysv.
7835 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7854 fix i960+non-bfd coff bit rot.
7855 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
7856 support for C source listings. (obj_coff_endef): look in the right

7859 * tc-m68k.c (get_num): make it work for all segments, not just the
7862 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
7864 * configure.in: recognize i386-*-bsd emulation.

7873 * tc-z8k.c: lots of bug fixes
7875 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7877 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7878 #elif, since it is not supported by old compilers.
7879 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7880 couple of expressions in tc-m68k.c.
7882 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7884 * read.c (cons): If NO_RELOC is defined, use it.
7886 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
7888 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
7890 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
7891 local labels to start with a .) and set REGISTER_PREFIX to %.
7892 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
7894 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
7896 * messages.c: Comment changes.
7898 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
7900 * as.h: Test if __STDC__ is defined only, don't test its value.
7901 * messages.c: If __STDC__ is not defined, define NO_STDARG.
7903 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
7905 * listing.c (debugging_pseudo): Add stabs and stabn as things to
7908 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7910 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7911 sections starting from zero, rather than making them consecutive.
7912 This makes subsequent reloc calculations easier, esp if the object
7913 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7914 allocate lcomm in .data rather than in .bss. It seems that some
7915 tools can't cope with a non-zero sized bss before linkage.
7917 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7919 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
7920 throughout. That enum no longer means what we thought it meant.
7922 * tc-m68k.c (md_assemble, md_parse_option): Handle new
7923 "-mno-688[58]1" options.
7925 * tc-m68k.c: Added CPU32 support.
7927 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7929 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

7933 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
7934 Change LIBDEPS dependence to LIBS.
7936 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
7938 * Makefile.in (install): if $(tooldir) exists, install as in
7941 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7943 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7944 .word is < -32768 or > 32767. The -J flag causes the error to be
7945 ignored. This is to catch over-sized switches generated by gcc on
7946 systems which don't support the broken .word hack.
7947 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7948 write.c (fixup_segment): check for signed .word overflow if
7949 WARN_SIGNED_OVERFLOW_WORD.
7951 * write.c (fixup_segment): fixed missing parens in expression
7952 checking for byte or word overflow.

8436 machine is a SPARC or a 29K.
8437 * config/obj-aout.c: added s_sect pseudo op
8438 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8439 fill in the timestamp.

8451 * read.c, write.c subsegs.c: back out the .bss changes.
8453 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8455 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

8461 * symbols.c (local_label_name): symbols now start with ^A.
8463 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8464 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8465 generate these sections. .align: will use NOP_OPCODE or 0
8466 for padding. This is just for being nice to the
8469 * expr.c (operand): changed to generate local label "\001L0"
8470 starting with a ^A so that it is recognized as a local label.
8472 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8474 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8475 i/o opcodes - inb, inw, outb and outw. string manipulation with
8476 att syntax - scmp, slod, smov, ssca, ssto.
8478 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8479 to just after .file .
8481 In obj_crawl_symbol_chain() where it tries to put the external
8482 symbols apart, with the condition:
8483 (!S_IS_DEFINED(symbolP) &&
8484 !S_IS_DEBUG(symbolP) &&
8485 !SF_GET_STATICS(symbolP))
8486 it was moving too many symbols out. So I switch it back to the
8488 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8490 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8491 so that we don't use the F_RELFLG which make the linker complain
8492 that somebody has stripped the relocation info.
8494 Also, the AIX ld program require that the relocation table
8495 is sorted by r_vaddr like the standard ATT assembler does.
8497 [he also changed the sizeof(struct ...)'s into the coff
8498 style FOOSZ macros. I'm not sure this is right, but I can't
8499 remember why. xoxorich.]

8503 * Makefile.in, configure.in, doc: use the doc. Build it, install
8506 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8508 * read.c: white space and comments only.
8510 * configure.in: use the new atof-ns32.c for ns32k.
8512 * write.c: comment change only.
8514 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8515 aren't yet integrated.
8517 * tc-i860.[hc]: blew off the dust. Something must still be done
8518 about conflicting relocation types.
8520 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8523 * tc-i960.c, tc-sparc.c: white space and comments only.
8525 * tc-a29k.h: delete duplicate macro definition.
8527 * new file atof-ns32k.c copied from hack's last unreleased gas.
8529 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8531 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8534 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8535 ChangeLog's prior to this are sketchy at best. I have logs.
8536 They just aren't ChangeLogs.
