125 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
126 not symbol_new, for symbols holding expression values.
127 * expr.h (make_expr_symbol): Move declaration here.
128 * write.c (fix_new_exp): Handle O_add by creating an
129 expression-valued symbol, and calling fix_new_exp recursively.
130 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
131 undefined symbol and a constant, fold the constant into the fixup,
132 and refer to the undefined symbol directly. Then process the
133 fixup again from scratch.
134 (write_object_file): Before calling adjust_reloc_syms, make a pass
135 through the symbol list trying to resolve values.
137 * write.c (print_fixup): New routine, for debugging.
138 (write_relocs): Call bfd_install_relocation. Deleted various
139 hacks for working around problems with bfd_perform_relocation.

158 RELOC_EXPANSION_POSSIBLE.
160 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
162 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
163 here. Use them for deciding which PRINTF*LIKE macro definitions

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

191 (listing_listing): Iterate fetching lines while line number is too
192 low, and we haven't run off the end of the input file.
194 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.

223 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
225 * config/vms-conf.h: new file, manually derived from conf.in.
226 * config-gas.com: use it, and eliminate obsolete "host.h".

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

245 * config/tc-mips.c (md_shortopts): Remove E.
246 (md_longopts): Add EB and EL.
247 (md_parse_option): Handle -EB and -EL as separate options, rather
248 than as a single -E option with an argument.
250 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
252 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
253 involving global symbols too.
255 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
257 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
259 * configure.in: Test for remove, not delete. Fix cross-assembler

271 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
272 many others): new macros; values obtained from "DSTRECRDS.SDL".
273 * config/obj-vms.h (various): use them.
274 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
275 representation (only enum bitfields can avoid being bitstrings).
276 (bitfield_suffix, setup_basic_type): new routines.
277 (VMS_typedef_parse): use them. Now recognize bitfields of all
278 integral types, not just type `int'. Caveat: the representation
279 used for bitfields still does not work for objects placed in
280 registers, and gcc's optimizer sometimes puts small structs there.
282 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
284 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
286 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
287 (tc_frob_label): define this to call vms_check_for_special_label,
288 and declare the latter.

293 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
294 and `gcc2_compiled.' labels; they won't reach here any more.
295 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
296 double', use `vax_g_doubles' flag to select type of double.
297 (VMS_write_object_file) [traceback setup]: don't pass symbols
298 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
299 and TBT_Routine_End functions.
301 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
303 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
304 S_GET_VALUE() to avoid many repeated function calls.
305 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
306 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
307 gets requested. [All the HACK_DEC_C_STARTUP code appears to
308 be obsolete; gcc does it automatically for vms target. It's
309 also misnamed, because it is for the "VAX C" run-time library,
310 not the newer "DEC C" one which has much different startup code.]
311 {various}: use `S_SET_xxx(symbol,new_value)' rather than
312 `S_GET_xxx(symbol) = new_value'.

316 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,

321 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
323 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
325 * expr.c (expr): Don't reduce the difference of two symbols in the
326 same frag if the symbols are not in normal sections.
328 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
329 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.

331 * config/tc-hppa.c: Delete whitespace at EOL.
332 (struct hppa_fix_struct): Delete fx_unwind field and all references.
333 (fix_new_hppa): Last arg is now a pointer to an int. Do not
334 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
335 fixups, store 32bits of unwind information in the fx_addnumber
337 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
338 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
339 pointer to 32 bits of unwind info.
340 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
341 pointer to the dummy symbol; set the addend field to fx_addnumber.
342 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
343 rather than &bfd_XXX_section.
345 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
347 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
348 value by one; discard adjustments previously being made. From
351 VMS- and Vax-related changes from Pat Rankin:
352 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
353 * vmsconf.sh: no longer have make-gas.com echo text about needing
354 to modify the gcc-vms driver when intending to use with gcc 1.x.
355 * as.c (parse_options): suppress 'v' from std_short_options and
356 eliminate VMS-specific conditional initialization;
357 [default case]: check for '-v' if md_parse_options doesn't recognize
359 [default case, #if VMS]: check for filename argument when '-v' seen;
361 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
362 for O_big literal operands (double floats and long long ints);
363 [VMS, md_shortopts]: add second colon after 'v';
364 (md_parse_options) [VMS, case 'v']: check for argument, so
365 caller can handle `-v' w/o arg.

417 * gdbinit.in: New file, created from old .gdbinit.
419 * aclocal.m4 (GAS_GDBINIT): Deleted.
420 * configure.in: Don't use it. Instead, generate .gdbinit from
421 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,

1425 * config/obj-coff.c (fixup_segment) [!BFD_ASSEMBLER]
1426 [DIFF_EXPR_OK]: Do conversion to pc-relative for difference, even
1427 if pcrel is already set.
1429 * read.c (potable): Add this_gcc_requires_the_gnu_assembler in all
1430 lower-case, in case we're ignoring case of opcodes in the input
1433 * doc/as.texinfo (.section): Document as unavailable for a.out
1436 * config/tc-alpha.c (machine): New variable.
1437 (load_insn): New macro.
1438 (load_insn_table): New function.
1439 (md_begin): Call load_insn_table, once for basic instructions and
1440 once for appropriate PAL instruction table.
1441 (md_parse_option): Set `machine' based on -m##### arguments.
1442 * config/alpha-opcode.h (alpha_pal21064_opcodes): Split out from

1461 * Makefile.in (VERSION): Updated to cygnus-2.3.1.
1463 * config/obj-vms.c: Replaced unchecked uses of malloc with
1466 * listing.c (list_symbol_table): Only test BFD64, not
1469 * config/obj-coff.c (fixup_segment) [BFD_ASSEMBLER]

1489 VMS debugger now recognizes `long long' variables correctly.
1490 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1491 for gcc2's predefined types "long double" (same as double, as
1492 per gcc's current state), "long long int", "long long unsigned
1493 int", and final `otherwise' case (to avoid uninitialized type
1494 and size fields). [caveat: predefined types "complex int",
1495 "complex float", "complex double", and "complex long double" are
1498 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
1499 of 0, because the latter indicates success rather than failure

1858 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
1860 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
1862 * vmsconf.sh: In generated file, get ".obj" suffix right, build
1863 source files from other directories into objects in the current
1864 directory, and specify PSECT attributes explicitly to linker.
1865 Also added missing label.
1866 * Makefile.in (stamp-mk.com): Reference new variable

1933 elf_tc_make_sections stuff. It was there to support PA braindamage
1934 which has been fixed, and in the case of elf_tc_make_sections is

1955 don't spew remainder of input file in error message.
1956 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error

1969 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
1970 flag rather than signedp field. Only permit extended range if
1971 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.

1974 * config/tc-ppc.c (ppc_size): New static variable.
1975 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
1976 (md_begin): If an instruction has a size specific flag set, only

1981 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
1982 cross section PC relative relocs right for COFF and ELF.
1984 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2009 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2010 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2012 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2013 branch with an instruction that uses $at, in case the branch is
2015 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2016 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2017 to make it pcrel_offset.
2018 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to

2028 (md_assemble): Call it.
2029 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2031 (lituse_pending): New variable. Set by anything that generates a
2032 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2033 tested by code that might want to emit a LITUSE reloc.
2034 (emit_unaligned_io): New function. Currently calls md_assemble,
2035 but it should eventually be converted to generate the insn itself
2036 and call emit_insn directly.
2037 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2038 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2039 emit_bis_r): Likewise.
2040 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2041 (alpha_ip, label get_macro): Don't emit the final instruction if
2043 (alpha_ip, case 'B', subcase 'd'): New case, for subword and

2050 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2051 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2052 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2067 (load_address): Handle EMBEDDED_PIC.
2068 (macro): Handle EMBEDDED_PIC in all PIC cases.
2069 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2070 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2071 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2072 works). Do not permit -G with SVR4_PIC.
2073 (s_abicalls): Warn if -G was used, and force -G 0.
2074 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2075 anything but a.out, not just for ELF. For ECOFF, don't generate a
2076 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2078 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.

2086 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2088 * Makefile.in (config-stamp): If `defs' is defined, emit a
2089 preprocessor directive to create a macro named by this value into
2090 config.new; don't explicitly go for BFD_ASSEMBLER.
2091 * configure.in: Define `defs', not `BFDDEF'. Set it to
2092 MANY_SEGMENTS for any obj-coffbfd target.
2093 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2094 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2096 (LOCAL_LOADLIBES): Deleted.
2097 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2098 * config/m88kcoff.mt (TDEFINES): Ditto.

2124 bfd_set_symtab is called.
2125 (dump_section_relocs): Note whether a symbol is a section symbol
2127 (adjust_reloc_syms): For now, always supply an absolute symbol for
2128 fixups without symbols but not yet `done'. Use section_symbol to
2129 get the symbol, instead of going directly for abs_symbol.
2130 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2131 reloc is not a section symbol and is not in the symbol table.
2132 (set_symtab): New function, broken out from write_object_file.
2133 Counts symbol table instead of relying on an earlier count.
2134 (write_object_file): Call set_symtab, but do it after potentially
2135 invoking the *_frob_file macros. Don't bother counting symbols.
2136 Call symbol_remove, instead of expanding it in place. Moved the
2137 conditionalized `object_file_size' declaration down to
2138 conditionalized block where it's used. When using the absolute
2139 symbol for a fixup without a symbol, set sy_used_in_reloc.
2140 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2141 the correct symbol for the absolute section.
2143 * subsegs.c (section_symbol): Use symbol_new instead of
2144 symbol_make, since we may want it to go into the symbol table.
2145 Make the new symbol have internal linkage. If
2146 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2147 symbol with the newly created GAS symbol.
2148 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2149 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2156 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2157 (sparc_ip, label "immediate"): Reject constants for pcrel
2158 instructions only if the relocation type indicates a "call"
2159 instruction and the offset is within range of a "jmpl %g0". If
2160 it's not in range, use the absolute section symbol plus an offset.
2161 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2163 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2165 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2168 * configure.in: Eliminated all targets using obj-coff but not
2169 defining BFD_ASSEMBLER; I think all such targets that are
2170 supported will be matched by real CPU-OS combinations earlier in
2172 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2173 some comments about the dpx2 configuration, but left it disabled,
2174 since it couldn't be reached before.
2175 (target a29k-amd-ebmonold): Deleted.
2177 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2185 the 'j' operand if there are no further alternatives for this
2188 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2189 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2190 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2192 * config/tc-mips.c (mips_align): Take new argument, label, and use
2193 it instead of global insn_label.
2194 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2195 call to mips_emit_delay and pass it to mips_align.
2197 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2199 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2201 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2202 argument to a .callinfo directive. Don't loop forever on errors.
2204 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2205 use pre-defined registers as arguments.

2210 S_IS_EXTERNAL when deciding whether to discard a symbol.
2212 * config-gas.com: Scan Makefile.in, not version.c, for current

2217 values to reduce number of lookups with S_GET_VALUE. Skip debug
2218 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2219 holger@botbso.rhein-main.de.)
2220 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2221 field. (Also from Holger Teutsch.) Watch for a would-be register
2222 mask that spans frags.
2224 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2225 this_base, not line_base. (Patch from Andreas Arens,

2228 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2229 look local if they're exported or undefined. Used to be done for
2232 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2233 Get it from the looked-up symbol, instead of using the string from
2234 the input stream, which is no longer null-terminated.
2235 (LEX_PCT): New macro, defaults to 0.
2236 (lex_type): Use it for `%'.
2238 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2288 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2289 0xffff for 'j' to be compatible with MIPS assembler. These
2290 numbers are actually treated as negative.

2306 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

4245 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4246 the table, require that the one without bit 0x1000000 set come
4247 first. Require further that it be case 'b' or 'P'. The a29k
4248 opcode table already meets these constraints.
4249 (machine_ip): When handling case 'i' or 'A', make sure that the
4250 appropriate opcode really exists by looking at the next entry in

4305 * write.c (write_relocs): For relocs that are pc_relative and
4306 pcrel_offset and not partial_inplace, adjust reloc->addend to

4357 OPTIONAL_REGISTER_PREFIX if either is already defined.
4359 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4361 * configure.in: Set bfd_gas for all sparc targets. Added facility
4362 for keeping or rejecting configurations still under development;
4363 default is to assume production environment, and reject configs
4364 still being worked on. Mark Elf configurations (except sparc and
4365 i386) as developmental. Deleted cases matching some generic names
4366 in favor of more specific names. (E.g., when we get Alpha

4384 for functions only used within tc-hppa.c, likewise for structures,
4385 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4386 conditional code in a few small places.
4388 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4389 structures, global variables, forward declarations together.

4391 conditional code -- try to group conditional code together
4392 into a few places. Make all functions and variables which
4393 are only used within tc-hppa.c static. PARAMize all functions.
4394 Add comments to functions. Delete unused functions, variables,
4395 #defines, etc. Delete unused members within structures. Delete
4396 ldil;ble hacks -- it is believed they were installed to work
4397 around old gas bugs. Avoid using mixed case for local
4398 functions, variables, and structures. Fix formatting problems
4399 not found by GNU-indent. Add FIXME notices for things which
4400 should be worked on the near future. Delete lots of old
4401 useless (1.36 PA-SOM) code.
4403 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type

4420 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
4421 of elf32_symbol_type.
4422 (pa_export_args): Likewise.

4430 a multiple of the section alignment rather than always a
4433 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4434 bits are zero (eg they specify no relocations), then do not even
4435 bother adding their entries to thesymextn section.

4479 of text, data and bss sections to 4.
4480 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4482 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4483 ELF, since the ELF object format does not have these type of
4484 relocations. Change the abort into as as_bad and return
4485 BFD_RELOC_NONE to silence compiler warnings.
4486 (md_assemble): Keep track of the instruction size. Allow white
4487 space between the $ and the constant for compatibility with older
4488 gases and other assemblers.
4489 (i386_operand): Skip spaces between $ and expression.

5564 type and to delay the computation of the expression until the
5565 value is actually needed. This permits setting symbols to values

6921 avoid some redefinition complaints on some systems.

6932 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

6939 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
6941 * Makefile.in: add dvi target; as-$(config).texinfo might live in

6972 dropping a space immediately following an identifier.

6974 lines; I don't think that can be done portably.
6975 * config/tc-mips.c (macro): Use $AT if target register is zero in

7002 to be on a single line.
7004 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
7006 * Makefile.in (config.h): Create file, writing out definitions of

7008 (ALL_CFLAGS): No longer define TARGET_CPU.
7010 * Makefile.in (check): Print a message, instead of quitting
7013 * as.c (main): Don't catch any signals, for now.

7050 prototypes for all static functions. Moved existing minimal
7051 debugging format support info #ifndef OBJ_ECOFF blocks.

7100 * make-gas.com: Find obstack.obj if it's not in the current
7102 * read.c (s_ignore): Don't declare is_end_of_line. It's
7103 redundant, and triggers a VMS gcc compiler bug.
7105 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7106 current segment as an argument. (Ignored in all cases but VMS.)
7107 All callers and definitions changed.

7131 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7134 * configure.in: mips-bsd configuration was missing format spec.
7137 * Makefile.in (Makefile): Depends on configure.in.
7139 * config/tc-mips.c (append_insn): Don't check for alignment of
7140 frag in memory; alignment of instructions in section is a separate

7160 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7161 constants are accepted, but symbolic values are not. GCC will not
7162 generate the latter currently.
7164 * frags.c (frag_init): New function.
7165 (zero_address_frag, bss_address_frag): Now initialized at run
7167 * as.c (main): Call frag_init.

7438 (operand): Treat zero byte as end-of-operand.
7440 * configure.in (per-target): Look for with_bfd_assembler option.
7441 For now, only accept "no", until the merge is done.
7443 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7444 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7445 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7446 * read.c: Finish conversion to S_* macros in the VMS only
7447 parts of the program. Add "const" modifier to hex_value.
7448 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7450 * expr.c: Add "const" modifier to hex_value.
7451 * symbols.c: Finish conversion to S_* macros in the VMS only
7452 parts of the program. Add "const" modifier to
7453 md_[long,short]_jump_size. Remove declaration of const_flag
7454 (which will be declared in obj-vms.h).
7455 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7456 Fix arguments to VMS_write_object_file.
7457 * config-gas.com: New file. Script for VMS systems to set up the
7458 configuration to build gas for VMS, and create config.status.
7459 * make-gas.com: Redone to work with new scheme.

7465 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7466 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7467 types of malformed stabs. Change parsing algorithm so that we are
7468 more certain of having all of the information that we need on hand.
7469 * obj-vms.c (final_forward_reference): New function, used to help
7470 resolve the data types of as many struct elements as possible
7471 when some part of the struct is not fully defined by the compiler.
7472 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
7474 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7475 as symbols as well in the object file. Look for external functions
7476 that start with "__vt.", and turn them into variables, since the
7477 g++ compiler is incapable of doing this.
7478 * tc-vax.c: Add '1' option for backward compatibility with older GCC
7480 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
7481 * input-scrub.c (as_where): Fix bug where as would crash if we did not
7482 have the name of the source file yet.
7483 * config/ho-vms.h: define HO_VMS, not HO_VAX.
7485 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
7487 * read.c (s_data): Always use "data_section", since it'll map to
7488 SEG_DATA or SEG_E1 if needed.
7489 (s_lcomm): Likewise with bss_section.
7490 (s_fill): Use memset, not bzero.
7492 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

7504 * Changes for BFD_ASSEMBLER:
7505 * obj.h (obj_crawl_symbol_chain): Declare only if not
7507 (obj_header_append, obj_pre_write_hook): Ditto.
7508 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
7509 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
7510 (segment_name) If BFD_ASSEMBLER, look up BFD section name;

7514 (big_section, reg_section, pass1_section, diff_section,
7515 absent_section, text_section, data_section, bss_section): If
7516 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7517 mapping to segT enum values.

7519 if these are used or defined, if BFD_ASSEMBLER.
7520 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7521 subseg_new split into two functions.
7522 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7524 * as.h (volatile): Don't define if already defined.
7525 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7527 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7528 declare with format attribute for -Wformat checking.
7530 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7532 * app.c, config/tc-*.c: Don't include read.h, since it is already
7535 * These are based on patches from Minh Tran-le
7536 <mtranle@paris.intellicorp.com>.
7537 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7538 obj_format coffbfd and gas_target i386coff for target.
7539 (i[34]86-*-isc*): New host (uses sysv).
7540 * config/i386aix.mt: Removed (no longer used).
7541 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7543 (LDFLAGS): Added, defined as -shlib.
7544 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7545 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7546 (DOT_LABEL_PREFIX): Define.
7547 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7548 name rather than L0\001.

7551 * symbols.c, symbols.h (local_bss_counter): Removed.
7552 * write.c (write_object_file): bss no longer uses

7560 (size_section): Restored sanity check.
7561 (do_relocs_for): Base section address on s_paddr rather than
7562 computing it. Adjust a29k R_IHIHALF special case to account for
7563 section paddr (used to require paddr to be zero). If there are no
7564 reclos, set s_relptr to 0. Set relocation size in object_headers.
7565 (fill_section): Always set s_vaddr here, removing
7566 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7567 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7568 Set STYP_INFO for .comment.

7573 (do_linenos_for): Set lineno size in object_headers.
7574 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7575 set s_vaddr here. If string_byte_count remains 4, set it back to
7576 0, and only write strings out if there are some. Call
7577 fill_section before do_relocs_for and do_linenos_for.
7578 (obj_coff_section): Handle optional quoted second argument giving
7579 section characteristics.
7580 (obj_coff_bss): Added to handle .bss.
7581 (obj_coff_ident): Added to handle .ident (puts string in .comment

7584 (fixup_mdeps): Change to segment. Call frag_wane after
7586 (fixup_segment): Explicitly check S_IS_COMMON before making 386
7587 adjustment (already happened only for common symbols, but this is
7589 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

7601 (do_scrub_next_char): For \", return " not '.
7602 (symbol_chars): Now const.
7604 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7605 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7607 * config/obj-coff.h: Don't use #elif.
7609 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7610 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

7637 using ZERO_BASED_SEGMENTS.
7638 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7639 never set segment address for SEG_E2 (.bss) and don't write out
7640 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7641 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7642 definitions, and don't merge tags with non-tags. Check for .bf
7643 rather than just checking whether the second character is b and
7644 the third character is f.
7645 (obj_coff_val): gcc can generate values which we don't handle
7646 correctly; discard information for now, since it only affects the
7647 debugging information.

7649 (yank_symbols): Don't merge labels.
7650 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7798 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7801 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

7830 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7832 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
7833 constant will not fit in an immediate field.
7834 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

7869 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
7871 * Support for i386-sysv.
7872 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7909 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
7910 * tc-z8k.c: lots of bug fixes
7912 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7914 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7915 #elif, since it is not supported by old compilers.
7916 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7917 couple of expressions in tc-m68k.c.
7919 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7921 * read.c (cons): If NO_RELOC is defined, use it.
7923 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
7925 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
7927 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
7928 local labels to start with a .) and set REGISTER_PREFIX to %.
7929 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
7931 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
7933 * messages.c: Comment changes.
7935 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

7945 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7947 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7948 sections starting from zero, rather than making them consecutive.
7949 This makes subsequent reloc calculations easier, esp if the object
7950 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7951 allocate lcomm in .data rather than in .bss. It seems that some
7952 tools can't cope with a non-zero sized bss before linkage.
7954 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7956 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
7957 throughout. That enum no longer means what we thought it meant.

7978 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7980 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7981 .word is < -32768 or > 32767. The -J flag causes the error to be
7982 ignored. This is to catch over-sized switches generated by gcc on
7983 systems which don't support the broken .word hack.
7984 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7985 write.c (fixup_segment): check for signed .word overflow if
7986 WARN_SIGNED_OVERFLOW_WORD.

8015 From Steve Chamberlain:
8016 Makefile.in: Handle m68*-*-coff*.
8017 read.c, read.h: add mult argument to s_space
8019 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8020 Motorola and MIT syntax; gas can now assemble either type of

8064 * config/tc-m68k.c (init_table): Now const. Always include 68851
8065 data, so that "bc" is available to 68040 cache instructions.
8066 Added "tt0", "tt1", and 68ec030 variants.
8067 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8068 (enum _register): Added TT0, TT1.
8069 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass

8096 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8097 has already been formatted (but may still contain %-characters).
8100 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8102 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8103 written with indirection on the last two operands, which can be
8104 either data or address registers. Added a new operand type 'r'
8105 which accepts either register type. Added '(' to notend stuff in
8106 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8453 local labels didn't work.
8454 * listing.c (list_symbol_table): don't core dump when there's no
8456 * write.c, write.h: call fix_new with the right number of args on
8458 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8461 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8463 * app.c: MRI compatibility - allow single quote to start a string.
8464 * as.c: fix typo recently introduced.
8465 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8466 * expr.c: Much rewriting, to accomodate MRI syntax for
8467 expressions. Also easier to read now.
8468 * listing.c: Put back defuns
8469 * read.c: modified to accept MRI syntax, put back listing pseudo
8470 ops so that an assembler built with NO_LISTING ignores list ops
8472 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8473 machine is a SPARC or a 29K.
8474 * config/obj-aout.c: added s_sect pseudo op
8475 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8476 fill in the timestamp.
8477 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8478 anymore, define all the relocs which the tc-<x> bit will use so we
8479 can translate from them to the coff types.
8480 * config/tc-a29k.c: reloc_type isn't ane enum any more
8481 * config/tc-m68k.c: Added NO_RELOC definition.
8483 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8485 * Makefile.in: put header files before C source for TAGS; remove
8486 references to non-existent syscalls.h.
8488 * read.c, write.c subsegs.c: back out the .bss changes.
8490 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8492 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8496 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8498 * symbols.c (local_label_name): symbols now start with ^A.
8500 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8501 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8502 generate these sections. .align: will use NOP_OPCODE or 0
8503 for padding. This is just for being nice to the
8506 * expr.c (operand): changed to generate local label "\001L0"
8507 starting with a ^A so that it is recognized as a local label.
8509 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8511 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8512 i/o opcodes - inb, inw, outb and outw. string manipulation with
8513 att syntax - scmp, slod, smov, ssca, ssto.
8515 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8516 to just after .file .
8518 In obj_crawl_symbol_chain() where it tries to put the external
8519 symbols apart, with the condition:
8520 (!S_IS_DEFINED(symbolP) &&
8521 !S_IS_DEBUG(symbolP) &&
8522 !SF_GET_STATICS(symbolP))
8523 it was moving too many symbols out. So I switch it back to the
8525 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8527 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8528 so that we don't use the F_RELFLG which make the linker complain
8529 that somebody has stripped the relocation info.
8531 Also, the AIX ld program require that the relocation table
8532 is sorted by r_vaddr like the standard ATT assembler does.
8534 [he also changed the sizeof(struct ...)'s into the coff
8535 style FOOSZ macros. I'm not sure this is right, but I can't
8536 remember why. xoxorich.]
8538 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8540 * Makefile.in, configure.in, doc: use the doc. Build it, install
8543 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8545 * read.c: white space and comments only.
8547 * configure.in: use the new atof-ns32.c for ns32k.
8549 * write.c: comment change only.
8551 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8552 aren't yet integrated.
8554 * tc-i860.[hc]: blew off the dust. Something must still be done
8555 about conflicting relocation types.
8557 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8560 * tc-i960.c, tc-sparc.c: white space and comments only.
8562 * tc-a29k.h: delete duplicate macro definition.
8564 * new file atof-ns32k.c copied from hack's last unreleased gas.
8566 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8568 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8571 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8572 ChangeLog's prior to this are sketchy at best. I have logs.
8573 They just aren't ChangeLogs.
8580 version-control: never
