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

82 Print segment name. Don't call print_expr_1 on an undefined
84 (print_expr_1): Fix whitespace before printing X_add_number.
86 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
87 not symbol_new, for symbols holding expression values.
88 * expr.h (make_expr_symbol): Move declaration here.
89 * write.c (fix_new_exp): Handle O_add by creating an
90 expression-valued symbol, and calling fix_new_exp recursively.
91 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
92 undefined symbol and a constant, fold the constant into the fixup,
93 and refer to the undefined symbol directly. Then process the
94 fixup again from scratch.
95 (write_object_file): Before calling adjust_reloc_syms, make a pass
96 through the symbol list trying to resolve values.
98 * write.c (print_fixup): New routine, for debugging.
99 (write_relocs): Call bfd_install_relocation. Deleted various
100 hacks for working around problems with bfd_perform_relocation.

108 * config/tc-mips.c: Include subsegs.h.
109 (md_apply_fix): If an unconditional b or bal overflows, and we are
110 not assembling PIC code, replace it with a j or jal.
112 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.

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

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

169 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
170 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
171 zero. Don't call obj_frob_forward_symbol.

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

197 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
198 from the csect of the enclosing block.
200 * config/tc-mips.c (insns_since_cache_access): Remove.
201 (append_insn): Remove setting of insns_since_cache_access, and

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

230 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
232 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
233 many others): new macros; values obtained from "DSTRECRDS.SDL".
234 * config/obj-vms.h (various): use them.
235 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
236 representation (only enum bitfields can avoid being bitstrings).
237 (bitfield_suffix, setup_basic_type): new routines.
238 (VMS_typedef_parse): use them. Now recognize bitfields of all
239 integral types, not just type `int'. Caveat: the representation
240 used for bitfields still does not work for objects placed in
241 registers, and gcc's optimizer sometimes puts small structs there.
243 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
245 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
247 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
248 (tc_frob_label): define this to call vms_check_for_special_label,
249 and declare the latter.
250 * config/obj-vms.c (vax_g_doubles): declare this file-scope
252 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
253 (vms_check_for_special_label): new routine (tc_frob_label).
254 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
255 and `gcc2_compiled.' labels; they won't reach here any more.
256 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
257 double', use `vax_g_doubles' flag to select type of double.
258 (VMS_write_object_file) [traceback setup]: don't pass symbols
259 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
260 and TBT_Routine_End functions.
262 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
264 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
265 S_GET_VALUE() to avoid many repeated function calls.
266 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
267 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
268 gets requested. [All the HACK_DEC_C_STARTUP code appears to
269 be obsolete; gcc does it automatically for vms target. It's
270 also misnamed, because it is for the "VAX C" run-time library,
271 not the newer "DEC C" one which has much different startup code.]
272 {various}: use `S_SET_xxx(symbol,new_value)' rather than
273 `S_GET_xxx(symbol) = new_value'.

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

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

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

440 value to pass to fix_new_exp.
441 (md_assemble): Change 32-bit reloc against GOT_symbol into a GOTPC
443 (i386_operand): Initialize disp_reloc field to NO_RELOC. Handle

1442 VMS debugger now recognizes `long long' variables correctly.
1443 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1444 for gcc2's predefined types "long double" (same as double, as
1445 per gcc's current state), "long long int", "long long unsigned
1446 int", and final `otherwise' case (to avoid uninitialized type
1447 and size fields). [caveat: predefined types "complex int",
1448 "complex float", "complex double", and "complex long double" are
1451 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
1452 of 0, because the latter indicates success rather than failure

1456 hardcoded `0xa3's with macro DBG_S_C_ADVANCED_TYPE from obj-vms.h.

1817 directory, and specify PSECT attributes explicitly to linker.
1818 Also added missing label.

1927 * config/tc-ppc.c (ppc_size): New static variable.
1928 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
1929 (md_begin): If an instruction has a size specific flag set, only
1930 add it if we are assembling that size.

1965 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
1966 branch with an instruction that uses $at, in case the branch is

1970 to make it pcrel_offset.
1971 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to

1981 (md_assemble): Call it.
1982 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
1984 (lituse_pending): New variable. Set by anything that generates a
1985 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
1986 tested by code that might want to emit a LITUSE reloc.
1987 (emit_unaligned_io): New function. Currently calls md_assemble,
1988 but it should eventually be converted to generate the insn itself
1989 and call emit_insn directly.
1990 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
1991 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

2003 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2004 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

2021 (macro): Handle EMBEDDED_PIC in all PIC cases.
2022 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2023 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2024 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2025 works). Do not permit -G with SVR4_PIC.
2026 (s_abicalls): Warn if -G was used, and force -G 0.
2027 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2028 anything but a.out, not just for ELF. For ECOFF, don't generate a

2039 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2041 * Makefile.in (config-stamp): If `defs' is defined, emit a
2042 preprocessor directive to create a macro named by this value into
2043 config.new; don't explicitly go for BFD_ASSEMBLER.
2044 * configure.in: Define `defs', not `BFDDEF'. Set it to
2045 MANY_SEGMENTS for any obj-coffbfd target.
2046 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2047 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,

2077 bfd_set_symtab is called.
2078 (dump_section_relocs): Note whether a symbol is a section symbol
2080 (adjust_reloc_syms): For now, always supply an absolute symbol for
2081 fixups without symbols but not yet `done'. Use section_symbol to
2082 get the symbol, instead of going directly for abs_symbol.
2083 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2084 reloc is not a section symbol and is not in the symbol table.
2085 (set_symtab): New function, broken out from write_object_file.
2086 Counts symbol table instead of relying on an earlier count.
2087 (write_object_file): Call set_symtab, but do it after potentially
2088 invoking the *_frob_file macros. Don't bother counting symbols.
2089 Call symbol_remove, instead of expanding it in place. Moved the
2090 conditionalized `object_file_size' declaration down to
2091 conditionalized block where it's used. When using the absolute
2092 symbol for a fixup without a symbol, set sy_used_in_reloc.
2093 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2094 the correct symbol for the absolute section.
2096 * subsegs.c (section_symbol): Use symbol_new instead of
2097 symbol_make, since we may want it to go into the symbol table.
2098 Make the new symbol have internal linkage. If
2099 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2100 symbol with the newly created GAS symbol.
2101 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2102 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2107 (in_signed_range): New function.
2109 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2110 (sparc_ip, label "immediate"): Reject constants for pcrel
2111 instructions only if the relocation type indicates a "call"
2112 instruction and the offset is within range of a "jmpl %g0". If
2113 it's not in range, use the absolute section symbol plus an offset.
2114 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2116 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2118 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2121 * configure.in: Eliminated all targets using obj-coff but not
2122 defining BFD_ASSEMBLER; I think all such targets that are
2123 supported will be matched by real CPU-OS combinations earlier in
2125 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2126 some comments about the dpx2 configuration, but left it disabled,
2127 since it couldn't be reached before.
2128 (target a29k-amd-ebmonold): Deleted.
2130 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2138 the 'j' operand if there are no further alternatives for this
2141 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2142 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2143 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2145 * config/tc-mips.c (mips_align): Take new argument, label, and use
2146 it instead of global insn_label.
2147 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2148 call to mips_emit_delay and pass it to mips_align.
2150 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2152 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2154 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2155 argument to a .callinfo directive. Don't loop forever on errors.

2163 S_IS_EXTERNAL when deciding whether to discard a symbol.
2165 * config-gas.com: Scan Makefile.in, not version.c, for current
2166 version number. Delete all versions of temp files when finished
2167 with them. Create config.h.
2169 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2170 values to reduce number of lookups with S_GET_VALUE. Skip debug
2171 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2172 holger@botbso.rhein-main.de.)
2173 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2174 field. (Also from Holger Teutsch.) Watch for a would-be register
2175 mask that spans frags.
2177 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2178 this_base, not line_base. (Patch from Andreas Arens,

2182 look local if they're exported or undefined. Used to be done for
2185 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

2187 the input stream, which is no longer null-terminated.
2188 (LEX_PCT): New macro, defaults to 0.
2189 (lex_type): Use it for `%'.
2191 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2241 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2242 0xffff for 'j' to be compatible with MIPS assembler. These

4316 default is to assume production environment, and reject configs
4317 still being worked on. Mark Elf configurations (except sparc and
4318 i386) as developmental. Deleted cases matching some generic names
4319 in favor of more specific names. (E.g., when we get Alpha

4345 into a few places. Make all functions and variables which
4346 are only used within tc-hppa.c static. PARAMize all functions.
4347 Add comments to functions. Delete unused functions, variables,
4348 #defines, etc. Delete unused members within structures. Delete
4349 ldil;ble hacks -- it is believed they were installed to work
4350 around old gas bugs. Avoid using mixed case for local
4351 functions, variables, and structures. Fix formatting problems
4352 not found by GNU-indent. Add FIXME notices for things which
4353 should be worked on the near future. Delete lots of old
4354 useless (1.36 PA-SOM) code.

4374 of elf32_symbol_type.
4375 (pa_export_args): Likewise.

4383 a multiple of the section alignment rather than always a
4386 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4387 bits are zero (eg they specify no relocations), then do not even
4388 bother adding their entries to thesymextn section.

4433 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4435 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4436 ELF, since the ELF object format does not have these type of
4437 relocations. Change the abort into as as_bad and return
4438 BFD_RELOC_NONE to silence compiler warnings.
4439 (md_assemble): Keep track of the instruction size. Allow white
4440 space between the $ and the constant for compatibility with older
4441 gases and other assemblers.

6885 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

6892 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

6925 dropping a space immediately following an identifier.

6927 lines; I don't think that can be done portably.
6928 * config/tc-mips.c (macro): Use $AT if target register is zero in

7053 * make-gas.com: Find obstack.obj if it's not in the current
7055 * read.c (s_ignore): Don't declare is_end_of_line. It's
7056 redundant, and triggers a VMS gcc compiler bug.
7058 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7059 current segment as an argument. (Ignored in all cases but VMS.)
7060 All callers and definitions changed.

7118 (zero_address_frag, bss_address_frag): Now initialized at run
7120 * as.c (main): Call frag_init.

7391 (operand): Treat zero byte as end-of-operand.
7393 * configure.in (per-target): Look for with_bfd_assembler option.
7394 For now, only accept "no", until the merge is done.
7396 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7397 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

7403 * expr.c: Add "const" modifier to hex_value.
7404 * symbols.c: Finish conversion to S_* macros in the VMS only
7405 parts of the program. Add "const" modifier to
7406 md_[long,short]_jump_size. Remove declaration of const_flag
7407 (which will be declared in obj-vms.h).
7408 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7409 Fix arguments to VMS_write_object_file.
7410 * config-gas.com: New file. Script for VMS systems to set up the
7411 configuration to build gas for VMS, and create config.status.

7419 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7420 types of malformed stabs. Change parsing algorithm so that we are
7421 more certain of having all of the information that we need on hand.

7427 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7428 as symbols as well in the object file. Look for external functions

7472 if these are used or defined, if BFD_ASSEMBLER.
7473 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7474 subseg_new split into two functions.
7475 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7477 * as.h (volatile): Don't define if already defined.
7478 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7480 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7481 declare with format attribute for -Wformat checking.
7483 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7485 * app.c, config/tc-*.c: Don't include read.h, since it is already
7488 * These are based on patches from Minh Tran-le
7489 <mtranle@paris.intellicorp.com>.
7490 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7491 obj_format coffbfd and gas_target i386coff for target.
7492 (i[34]86-*-isc*): New host (uses sysv).
7493 * config/i386aix.mt: Removed (no longer used).
7494 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7496 (LDFLAGS): Added, defined as -shlib.
7497 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7498 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7499 (DOT_LABEL_PREFIX): Define.
7500 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7501 name rather than L0\001.
7502 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7504 * symbols.c, symbols.h (local_bss_counter): Removed.
7505 * write.c (write_object_file): bss no longer uses
7506 local_bss_counter. Pass correct data and bss size to
7507 VMS_write_object_file.

7511 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
7512 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
7513 (size_section): Restored sanity check.
7514 (do_relocs_for): Base section address on s_paddr rather than
7515 computing it. Adjust a29k R_IHIHALF special case to account for
7516 section paddr (used to require paddr to be zero). If there are no
7517 reclos, set s_relptr to 0. Set relocation size in object_headers.
7518 (fill_section): Always set s_vaddr here, removing
7519 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7520 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7521 Set STYP_INFO for .comment.
7522 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7523 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7525 H_{SET,GET}_* macros.
7526 (do_linenos_for): Set lineno size in object_headers.
7527 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7528 set s_vaddr here. If string_byte_count remains 4, set it back to
7529 0, and only write strings out if there are some. Call
7530 fill_section before do_relocs_for and do_linenos_for.
7531 (obj_coff_section): Handle optional quoted second argument giving
7532 section characteristics.
7533 (obj_coff_bss): Added to handle .bss.
7534 (obj_coff_ident): Added to handle .ident (puts string in .comment
7536 (obj_coff_lcomm): Put common symbols in .bss, not .data.
7537 (fixup_mdeps): Change to segment. Call frag_wane after
7539 (fixup_segment): Explicitly check S_IS_COMMON before making 386
7540 adjustment (already happened only for common symbols, but this is
7542 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
7543 * config/tc-i386.c (s_bss): Don't use if I386COFF.

7554 (do_scrub_next_char): For \", return " not '.
7555 (symbol_chars): Now const.
7557 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7558 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7560 * config/obj-coff.h: Don't use #elif.
7562 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7563 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

7589 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7590 using ZERO_BASED_SEGMENTS.
7591 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7592 never set segment address for SEG_E2 (.bss) and don't write out
7593 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7594 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7595 definitions, and don't merge tags with non-tags. Check for .bf
7596 rather than just checking whether the second character is b and
7597 the third character is f.
7598 (obj_coff_val): gcc can generate values which we don't handle
7599 correctly; discard information for now, since it only affects the
7600 debugging information.

7602 (yank_symbols): Don't merge labels.
7603 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7609 relative addends by the segment vaddr.
7610 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
7611 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

7748 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
7749 could be doing emulation.
7751 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7754 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

7783 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7785 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
7786 constant will not fit in an immediate field.
7787 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

7822 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
7824 * Support for i386-sysv.
7825 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7849 * tc-m68k.c (get_num): make it work for all segments, not just the
7852 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
7854 * configure.in: recognize i386-*-bsd emulation.

7863 * tc-z8k.c: lots of bug fixes
7865 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7867 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7868 #elif, since it is not supported by old compilers.
7869 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7870 couple of expressions in tc-m68k.c.
7872 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7874 * read.c (cons): If NO_RELOC is defined, use it.
7876 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
7878 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
7880 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
7881 local labels to start with a .) and set REGISTER_PREFIX to %.
7882 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
7884 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
7886 * messages.c: Comment changes.
7888 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

7891 * messages.c: If __STDC__ is not defined, define NO_STDARG.
7893 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
7895 * listing.c (debugging_pseudo): Add stabs and stabn as things to
7898 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7900 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7901 sections starting from zero, rather than making them consecutive.
7902 This makes subsequent reloc calculations easier, esp if the object
7903 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7904 allocate lcomm in .data rather than in .bss. It seems that some
7905 tools can't cope with a non-zero sized bss before linkage.
7907 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7909 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
7910 throughout. That enum no longer means what we thought it meant.
7912 * tc-m68k.c (md_assemble, md_parse_option): Handle new
7913 "-mno-688[58]1" options.
7915 * tc-m68k.c: Added CPU32 support.
7917 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

7923 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
7924 Change LIBDEPS dependence to LIBS.
7926 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
7928 * Makefile.in (install): if $(tooldir) exists, install as in
7931 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7933 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7934 .word is < -32768 or > 32767. The -J flag causes the error to be
7935 ignored. This is to catch over-sized switches generated by gcc on
7936 systems which don't support the broken .word hack.
7937 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7938 write.c (fixup_segment): check for signed .word overflow if
7939 WARN_SIGNED_OVERFLOW_WORD.
7941 * write.c (fixup_segment): fixed missing parens in expression
7942 checking for byte or word overflow.
7944 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
7945 obj-coffbfd.c (fixup_segment): check for signed .word overflow if

7953 Support for i386 coff
7954 * obj-coffbfd.h : added stuff
7955 * tc-i386.c (tc_coff_fix2rtype): new function
7956 * tc-i386.h : new coff defines
7958 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)

7972 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
7973 Motorola and MIT syntax; gas can now assemble either type of

8055 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8056 written with indirection on the last two operands, which can be
8057 either data or address registers. Added a new operand type 'r'
8058 which accepts either register type. Added '(' to notend stuff in
8059 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8398 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8400 * expr.c: If an expression is single comma, then return with
8401 SEG_ABSENT rather than an error - since the sparc front end does
8402 really strange things with things like fbge,a
8404 * as.h: include bfd.h if using many sections
8405 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8406 local labels didn't work.

8409 * write.c, write.h: call fix_new with the right number of args on
8411 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8414 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8416 * app.c: MRI compatibility - allow single quote to start a string.

8418 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8419 * expr.c: Much rewriting, to accomodate MRI syntax for
8420 expressions. Also easier to read now.
8421 * listing.c: Put back defuns
8422 * read.c: modified to accept MRI syntax, put back listing pseudo
8423 ops so that an assembler built with NO_LISTING ignores list ops
8425 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8426 machine is a SPARC or a 29K.
8427 * config/obj-aout.c: added s_sect pseudo op
8428 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8429 fill in the timestamp.
8430 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8431 anymore, define all the relocs which the tc-<x> bit will use so we
8432 can translate from them to the coff types.
8433 * config/tc-a29k.c: reloc_type isn't ane enum any more
8434 * config/tc-m68k.c: Added NO_RELOC definition.
8436 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)

8449 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8451 * symbols.c (local_label_name): symbols now start with ^A.
8453 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8454 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8455 generate these sections. .align: will use NOP_OPCODE or 0
8456 for padding. This is just for being nice to the
8459 * expr.c (operand): changed to generate local label "\001L0"
8460 starting with a ^A so that it is recognized as a local label.
8462 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8464 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8465 i/o opcodes - inb, inw, outb and outw. string manipulation with
8466 att syntax - scmp, slod, smov, ssca, ssto.
8468 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8469 to just after .file .
8471 In obj_crawl_symbol_chain() where it tries to put the external
8472 symbols apart, with the condition:
8473 (!S_IS_DEFINED(symbolP) &&
8474 !S_IS_DEBUG(symbolP) &&
8475 !SF_GET_STATICS(symbolP))
8476 it was moving too many symbols out. So I switch it back to the
8478 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8480 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8481 so that we don't use the F_RELFLG which make the linker complain
8482 that somebody has stripped the relocation info.
8484 Also, the AIX ld program require that the relocation table
8485 is sorted by r_vaddr like the standard ATT assembler does.
8487 [he also changed the sizeof(struct ...)'s into the coff
8488 style FOOSZ macros. I'm not sure this is right, but I can't
8489 remember why. xoxorich.]

8493 * Makefile.in, configure.in, doc: use the doc. Build it, install
8496 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8498 * read.c: white space and comments only.
8500 * configure.in: use the new atof-ns32.c for ns32k.
8502 * write.c: comment change only.
8504 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8505 aren't yet integrated.
8507 * tc-i860.[hc]: blew off the dust. Something must still be done
8508 about conflicting relocation types.
8510 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8513 * tc-i960.c, tc-sparc.c: white space and comments only.
8515 * tc-a29k.h: delete duplicate macro definition.
8517 * new file atof-ns32k.c copied from hack's last unreleased gas.
8519 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8521 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8524 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8525 ChangeLog's prior to this are sketchy at best. I have logs.
8526 They just aren't ChangeLogs.
