47 If PC-relative fixup refers to a PLT entry for a symbol in the
48 current section, don't reduce it.
50 * write.c (adjust_reloc_syms): Exit loop through a label. If
51 DEBUG5 is defined, print out each fixup before and after
53 (fixup_segment): If DEBUG5 is defined, print out each fixup before

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

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

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

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

178 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
179 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is

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

206 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
207 from the csect of the enclosing block.
209 * config/tc-mips.c (insns_since_cache_access): Remove.
210 (append_insn): Remove setting of insns_since_cache_access, and

213 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
215 * config/tc-mips.c (md_shortopts): Remove E.
216 (md_longopts): Add EB and EL.
217 (md_parse_option): Handle -EB and -EL as separate options, rather
218 than as a single -E option with an argument.
220 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
222 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
223 involving global symbols too.
225 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
227 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
229 * configure.in: Test for remove, not delete. Fix cross-assembler

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

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

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

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

386 Update for autoconf 1.118:
387 * gdbinit.in: New file, created from old .gdbinit.
389 * aclocal.m4 (GAS_GDBINIT): Deleted.
390 * configure.in: Don't use it. Instead, generate .gdbinit from
391 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
392 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
393 to ensure that older versions of autoconf aren't used.
394 * Makefile.in: Added @configure_input@ line.

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

450 (md_assemble): Change 32-bit reloc against GOT_symbol into a GOTPC
452 (i386_operand): Initialize disp_reloc field to NO_RELOC. Handle

1427 Fri May 27 10:05:53 1994 Ken Raeburn (raeburn@cygnus.com)
1429 Merged in changes from gas-2.3 net release:
1431 * Makefile.in (VERSION): Updated to cygnus-2.3.1.
1433 * config/obj-vms.c: Replaced unchecked uses of malloc with
1436 * listing.c (list_symbol_table): Only test BFD64, not
1439 * config/obj-coff.c (fixup_segment) [BFD_ASSEMBLER]
1440 [DIFF_EXPR_OK]: Don't check pcrel, just convert it.
1442 * config/obj-vms.c: Removed lots of extra semicolons after
1443 compound statements.
1444 (strchr): Don't declare here.
1446 * config/ho-vax.h (realloc): Declare.

1458 DSC$K_DTYPE_QU and DSC$K_DTYPE_Q macros in <descrip.h>. The
1459 VMS debugger now recognizes `long long' variables correctly.
1460 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1461 for gcc2's predefined types "long double" (same as double, as
1462 per gcc's current state), "long long int", "long long unsigned
1463 int", and final `otherwise' case (to avoid uninitialized type
1464 and size fields). [caveat: predefined types "complex int",
1465 "complex float", "complex double", and "complex long double" are
1468 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
1469 of 0, because the latter indicates success rather than failure
1470 when passed to `exit' or return from `main' compiled by gcc2.
1472 * config/obj-vms.c (array_suffix, generate_suffix): replace two
1473 hardcoded `0xa3's with macro DBG_S_C_ADVANCED_TYPE from obj-vms.h.
1474 (VMS_typedef_parse): eliminate redundant if-then-else when
1475 allocating new symbol entry and linking it to VMS_Symbol_type_list.
1477 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
1479 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret
1480 the contents of the GAS_VERSION string when falling back to it for
1481 language processor identification.
1483 * make-gas.com, vmsconf.sh (ENVIRON): fix misspelling of
1484 `psect_attr' in linker options.

1512 * config/tc-hppa.c (pa_parse_fp_cmp_cond): Report an error
1513 on a partial completer match.

1900 (hppa_tc_symbol): Likewise.
1902 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
1903 elf_tc_make_sections stuff. It was there to support PA braindamage
1904 which has been fixed, and in the case of elf_tc_make_sections is
1905 redundant with elf_tc_final_processing.

1924 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
1925 don't spew remainder of input file in error message.
1926 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
1927 message with reloc type and try to process remainder of file.
1929 * doc/Makefile.in (install-info-as, install-info-gasp): New
1930 targets, now explicitly checking $(srcdir) for info files.
1931 (install-info): Depend on both of them; do nothing more.

1939 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
1940 flag rather than signedp field. Only permit extended range if
1941 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
1942 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
1944 * config/tc-ppc.c (ppc_size): New static variable.
1945 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
1946 (md_begin): If an instruction has a size specific flag set, only
1947 add it if we are assembling that size.

1951 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
1952 cross section PC relative relocs right for COFF and ELF.
1954 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1956 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
1957 (OBJ_PROCESS_STAB): Don't define.

1962 the type of symbol set symbols which happen to be in the absolute
1963 or undefined section.

1979 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
1980 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
1982 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
1983 branch with an instruction that uses $at, in case the branch is
1985 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
1986 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
1987 to make it pcrel_offset.
1988 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
1989 reloc->address; another gruesome hack to get gas reloc handling to

1994 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
1997 (emit_insn): New function.
1998 (md_assemble): Call it.
1999 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2001 (lituse_pending): New variable. Set by anything that generates a
2002 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2003 tested by code that might want to emit a LITUSE reloc.
2004 (emit_unaligned_io): New function. Currently calls md_assemble,
2005 but it should eventually be converted to generate the insn itself
2006 and call emit_insn directly.
2007 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2008 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2009 emit_bis_r): Likewise.
2010 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2011 (alpha_ip, label get_macro): Don't emit the final instruction if
2013 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2014 unaligned memory access macros.

2018 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2020 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2021 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2022 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2034 * config/tc-mips.c (enum mips_pic_level): New enum.
2035 (mips_pic): Change from int to enum mips_pic_level. Change all
2036 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2037 (load_address): Handle EMBEDDED_PIC.
2038 (macro): Handle EMBEDDED_PIC in all PIC cases.
2039 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2040 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2041 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2042 works). Do not permit -G with SVR4_PIC.
2043 (s_abicalls): Warn if -G was used, and force -G 0.
2044 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2045 anything but a.out, not just for ELF. For ECOFF, don't generate a
2046 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2048 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2050 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2052 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2053 parameters to avoid losing when compiling with HP CC.
2054 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2056 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2058 * Makefile.in (config-stamp): If `defs' is defined, emit a
2059 preprocessor directive to create a macro named by this value into
2060 config.new; don't explicitly go for BFD_ASSEMBLER.
2061 * configure.in: Define `defs', not `BFDDEF'. Set it to
2062 MANY_SEGMENTS for any obj-coffbfd target.
2063 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2064 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2066 (LOCAL_LOADLIBES): Deleted.
2067 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2068 * config/m88kcoff.mt (TDEFINES): Ditto.

2072 * config/sparc.mt: Deleted.
2073 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

2094 bfd_set_symtab is called.
2095 (dump_section_relocs): Note whether a symbol is a section symbol
2097 (adjust_reloc_syms): For now, always supply an absolute symbol for
2098 fixups without symbols but not yet `done'. Use section_symbol to
2099 get the symbol, instead of going directly for abs_symbol.
2100 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2101 reloc is not a section symbol and is not in the symbol table.
2102 (set_symtab): New function, broken out from write_object_file.
2103 Counts symbol table instead of relying on an earlier count.
2104 (write_object_file): Call set_symtab, but do it after potentially
2105 invoking the *_frob_file macros. Don't bother counting symbols.
2106 Call symbol_remove, instead of expanding it in place. Moved the
2107 conditionalized `object_file_size' declaration down to
2108 conditionalized block where it's used. When using the absolute
2109 symbol for a fixup without a symbol, set sy_used_in_reloc.
2110 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2111 the correct symbol for the absolute section.
2113 * subsegs.c (section_symbol): Use symbol_new instead of
2114 symbol_make, since we may want it to go into the symbol table.
2115 Make the new symbol have internal linkage. If
2116 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2117 symbol with the newly created GAS symbol.
2118 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2119 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2124 (in_signed_range): New function.
2126 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2127 (sparc_ip, label "immediate"): Reject constants for pcrel
2128 instructions only if the relocation type indicates a "call"
2129 instruction and the offset is within range of a "jmpl %g0". If
2130 it's not in range, use the absolute section symbol plus an offset.
2131 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2133 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2135 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2138 * configure.in: Eliminated all targets using obj-coff but not
2139 defining BFD_ASSEMBLER; I think all such targets that are
2140 supported will be matched by real CPU-OS combinations earlier in
2142 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2143 some comments about the dpx2 configuration, but left it disabled,
2144 since it couldn't be reached before.
2145 (target a29k-amd-ebmonold): Deleted.
2147 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2155 the 'j' operand if there are no further alternatives for this
2158 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2159 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2160 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2162 * config/tc-mips.c (mips_align): Take new argument, label, and use
2163 it instead of global insn_label.
2164 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2165 call to mips_emit_delay and pass it to mips_align.
2167 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2169 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2171 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2172 argument to a .callinfo directive. Don't loop forever on errors.
2174 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2175 use pre-defined registers as arguments.

2179 * write.c (write_object_file): Check both S_IS_LOCAL and
2180 S_IS_EXTERNAL when deciding whether to discard a symbol.
2182 * config-gas.com: Scan Makefile.in, not version.c, for current
2183 version number. Delete all versions of temp files when finished
2184 with them. Create config.h.
2186 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2187 values to reduce number of lookups with S_GET_VALUE. Skip debug
2188 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2189 holger@botbso.rhein-main.de.)
2190 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2191 field. (Also from Holger Teutsch.) Watch for a would-be register
2192 mask that spans frags.
2194 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2195 this_base, not line_base. (Patch from Andreas Arens,
2196 ari@obelix.av.rwth-aachen.de.)
2198 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2199 look local if they're exported or undefined. Used to be done for
2202 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2203 Get it from the looked-up symbol, instead of using the string from
2204 the input stream, which is no longer null-terminated.
2205 (LEX_PCT): New macro, defaults to 0.
2206 (lex_type): Use it for `%'.
2208 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2209 (vip_op): Now static, and returns void. Callers changed. Added
2211 (vip): Ditto. Call as_fatal directly if a program bug is

2258 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2259 0xffff for 'j' to be compatible with MIPS assembler. These
2260 numbers are actually treated as negative.

2276 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

4215 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4216 the table, require that the one without bit 0x1000000 set come
4217 first. Require further that it be case 'b' or 'P'. The a29k
4218 opcode table already meets these constraints.
4219 (machine_ip): When handling case 'i' or 'A', make sure that the

4332 for keeping or rejecting configurations still under development;
4333 default is to assume production environment, and reject configs
4334 still being worked on. Mark Elf configurations (except sparc and
4335 i386) as developmental. Deleted cases matching some generic names
4336 in favor of more specific names. (E.g., when we get Alpha

4362 into a few places. Make all functions and variables which
4363 are only used within tc-hppa.c static. PARAMize all functions.
4364 Add comments to functions. Delete unused functions, variables,
4365 #defines, etc. Delete unused members within structures. Delete
4366 ldil;ble hacks -- it is believed they were installed to work
4367 around old gas bugs. Avoid using mixed case for local
4368 functions, variables, and structures. Fix formatting problems
4369 not found by GNU-indent. Add FIXME notices for things which
4370 should be worked on the near future. Delete lots of old
4371 useless (1.36 PA-SOM) code.

4450 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4452 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4453 ELF, since the ELF object format does not have these type of
4454 relocations. Change the abort into as as_bad and return
4455 BFD_RELOC_NONE to silence compiler warnings.
4456 (md_assemble): Keep track of the instruction size. Allow white
4457 space between the $ and the constant for compatibility with older
4458 gases and other assemblers.

6902 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

6909 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

6942 dropping a space immediately following an identifier.

6944 lines; I don't think that can be done portably.
6945 * config/tc-mips.c (macro): Use $AT if target register is zero in

7020 prototypes for all static functions. Moved existing minimal
7021 debugging format support info #ifndef OBJ_ECOFF blocks.

7070 * make-gas.com: Find obstack.obj if it's not in the current
7072 * read.c (s_ignore): Don't declare is_end_of_line. It's
7073 redundant, and triggers a VMS gcc compiler bug.
7075 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7076 current segment as an argument. (Ignored in all cases but VMS.)
7077 All callers and definitions changed.

7130 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7131 constants are accepted, but symbolic values are not. GCC will not
7132 generate the latter currently.
7134 * frags.c (frag_init): New function.
7135 (zero_address_frag, bss_address_frag): Now initialized at run
7137 * as.c (main): Call frag_init.

7408 (operand): Treat zero byte as end-of-operand.
7410 * configure.in (per-target): Look for with_bfd_assembler option.
7411 For now, only accept "no", until the merge is done.
7413 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7414 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7415 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7416 * read.c: Finish conversion to S_* macros in the VMS only
7417 parts of the program. Add "const" modifier to hex_value.
7418 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7420 * expr.c: Add "const" modifier to hex_value.
7421 * symbols.c: Finish conversion to S_* macros in the VMS only
7422 parts of the program. Add "const" modifier to
7423 md_[long,short]_jump_size. Remove declaration of const_flag
7424 (which will be declared in obj-vms.h).
7425 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7426 Fix arguments to VMS_write_object_file.
7427 * config-gas.com: New file. Script for VMS systems to set up the
7428 configuration to build gas for VMS, and create config.status.

7435 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7436 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7437 types of malformed stabs. Change parsing algorithm so that we are
7438 more certain of having all of the information that we need on hand.

7444 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7445 as symbols as well in the object file. Look for external functions

7477 (obj_header_append, obj_pre_write_hook): Ditto.
7478 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
7479 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
7480 (segment_name) If BFD_ASSEMBLER, look up BFD section name;
7481 otherwise, use seg_name array.
7482 (seg_name): Declare only if not BFD_ASSEMBLER.
7483 (section_alignment): Declare only if not BFD_ASSEMBLER.
7484 (big_section, reg_section, pass1_section, diff_section,
7485 absent_section, text_section, data_section, bss_section): If
7486 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7487 mapping to segT enum values.
7488 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7489 if these are used or defined, if BFD_ASSEMBLER.
7490 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7491 subseg_new split into two functions.
7492 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7494 * as.h (volatile): Don't define if already defined.
7495 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7497 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7498 declare with format attribute for -Wformat checking.
7500 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7502 * app.c, config/tc-*.c: Don't include read.h, since it is already
7505 * These are based on patches from Minh Tran-le
7506 <mtranle@paris.intellicorp.com>.
7507 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7508 obj_format coffbfd and gas_target i386coff for target.
7509 (i[34]86-*-isc*): New host (uses sysv).
7510 * config/i386aix.mt: Removed (no longer used).
7511 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7513 (LDFLAGS): Added, defined as -shlib.
7514 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7515 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7516 (DOT_LABEL_PREFIX): Define.
7517 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7518 name rather than L0\001.
7519 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7521 * symbols.c, symbols.h (local_bss_counter): Removed.
7522 * write.c (write_object_file): bss no longer uses
7523 local_bss_counter. Pass correct data and bss size to
7524 VMS_write_object_file.
7525 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
7526 argument, rather than using local_bss_counter.

7528 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
7529 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
7530 (size_section): Restored sanity check.
7531 (do_relocs_for): Base section address on s_paddr rather than
7532 computing it. Adjust a29k R_IHIHALF special case to account for
7533 section paddr (used to require paddr to be zero). If there are no
7534 reclos, set s_relptr to 0. Set relocation size in object_headers.
7535 (fill_section): Always set s_vaddr here, removing
7536 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7537 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7538 Set STYP_INFO for .comment.
7539 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7540 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7542 H_{SET,GET}_* macros.
7543 (do_linenos_for): Set lineno size in object_headers.
7544 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7545 set s_vaddr here. If string_byte_count remains 4, set it back to
7546 0, and only write strings out if there are some. Call
7547 fill_section before do_relocs_for and do_linenos_for.
7548 (obj_coff_section): Handle optional quoted second argument giving
7549 section characteristics.
7550 (obj_coff_bss): Added to handle .bss.
7551 (obj_coff_ident): Added to handle .ident (puts string in .comment
7553 (obj_coff_lcomm): Put common symbols in .bss, not .data.
7554 (fixup_mdeps): Change to segment. Call frag_wane after
7556 (fixup_segment): Explicitly check S_IS_COMMON before making 386
7557 adjustment (already happened only for common symbols, but this is
7559 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
7560 * config/tc-i386.c (s_bss): Don't use if I386COFF.

7570 * app.c (app_push): Use memcpy, not bcopy.
7571 (do_scrub_next_char): For \", return " not '.
7572 (symbol_chars): Now const.
7574 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7575 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7577 * config/obj-coff.h: Don't use #elif.
7579 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7580 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
7582 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

7604 SEG_BSS, fill with NOP_OPCODE.
7605 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
7606 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7607 using ZERO_BASED_SEGMENTS.
7608 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7609 never set segment address for SEG_E2 (.bss) and don't write out
7610 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7611 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7612 definitions, and don't merge tags with non-tags. Check for .bf
7613 rather than just checking whether the second character is b and
7614 the third character is f.
7615 (obj_coff_val): gcc can generate values which we don't handle
7616 correctly; discard information for now, since it only affects the
7617 debugging information.
7618 (tag_find_or_name): Don't insert tags in the symbol table.
7619 (yank_symbols): Don't merge labels.
7620 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7623 (obj_coff_section): Accept and ignore a trailing quoted string, as
7624 used in AT&T i386 syntax.
7625 (fixup_segment): Take segment as argument. On the i386, adjust PC
7626 relative addends by the segment vaddr.
7627 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
7628 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
7629 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

7675 options. Updated options documentation for m68k. Some minor
7676 wording/punctuation changes.

7730 xrealloc from xrealloc.c.
7731 * xrealloc.c: Deleted.
7732 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.

7765 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
7766 could be doing emulation.
7768 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7771 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
7774 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
7776 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

7798 consistently const, and always initialized them. Included read.h.
7800 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7802 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
7803 constant will not fit in an immediate field.
7804 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
7806 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

7839 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
7841 * Support for i386-sysv.
7842 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7846 (fill_section): Don't set STYP_NOLOAD for .bss section.
7847 (fixup_segment): 386 uses strange common symbol format.

7861 fix i960+non-bfd coff bit rot.
7862 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
7863 support for C source listings. (obj_coff_endef): look in the right
7864 part of the symbol for the symbol name
7866 * tc-m68k.c (get_num): make it work for all segments, not just the
7869 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
7871 * configure.in: recognize i386-*-bsd emulation.
7873 Thu Oct 1 23:05:12 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

7877 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7879 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
7880 * tc-z8k.c: lots of bug fixes
7882 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7884 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7885 #elif, since it is not supported by old compilers.
7886 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7887 couple of expressions in tc-m68k.c.
7889 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7891 * read.c (cons): If NO_RELOC is defined, use it.
7893 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
7895 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
7897 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
7898 local labels to start with a .) and set REGISTER_PREFIX to %.
7899 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
7901 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
7903 * messages.c: Comment changes.
7905 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
7907 * as.h: Test if __STDC__ is defined only, don't test its value.
7908 * messages.c: If __STDC__ is not defined, define NO_STDARG.
7910 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
7912 * listing.c (debugging_pseudo): Add stabs and stabn as things to
7915 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7917 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7918 sections starting from zero, rather than making them consecutive.
7919 This makes subsequent reloc calculations easier, esp if the object
7920 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7921 allocate lcomm in .data rather than in .bss. It seems that some
7922 tools can't cope with a non-zero sized bss before linkage.
7924 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7926 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
7927 throughout. That enum no longer means what we thought it meant.
7929 * tc-m68k.c (md_assemble, md_parse_option): Handle new
7930 "-mno-688[58]1" options.
7932 * tc-m68k.c: Added CPU32 support.
7934 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7936 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
7938 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7940 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
7941 Change LIBDEPS dependence to LIBS.
7943 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
7945 * Makefile.in (install): if $(tooldir) exists, install as in
7948 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7950 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7951 .word is < -32768 or > 32767. The -J flag causes the error to be
7952 ignored. This is to catch over-sized switches generated by gcc on

8443 machine is a SPARC or a 29K.
8444 * config/obj-aout.c: added s_sect pseudo op
8445 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8446 fill in the timestamp.
8447 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8448 anymore, define all the relocs which the tc-<x> bit will use so we

8450 * config/tc-a29k.c: reloc_type isn't ane enum any more
8451 * config/tc-m68k.c: Added NO_RELOC definition.
8453 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8455 * Makefile.in: put header files before C source for TAGS; remove
8456 references to non-existent syscalls.h.
8458 * read.c, write.c subsegs.c: back out the .bss changes.
8460 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8462 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

8468 * symbols.c (local_label_name): symbols now start with ^A.
8470 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8471 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8472 generate these sections. .align: will use NOP_OPCODE or 0
8473 for padding. This is just for being nice to the
8476 * expr.c (operand): changed to generate local label "\001L0"
8477 starting with a ^A so that it is recognized as a local label.
8479 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8481 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8482 i/o opcodes - inb, inw, outb and outw. string manipulation with
8483 att syntax - scmp, slod, smov, ssca, ssto.
8485 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8486 to just after .file .
8488 In obj_crawl_symbol_chain() where it tries to put the external
8489 symbols apart, with the condition:
8490 (!S_IS_DEFINED(symbolP) &&
8491 !S_IS_DEBUG(symbolP) &&
8492 !SF_GET_STATICS(symbolP))
8493 it was moving too many symbols out. So I switch it back to the
8495 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8497 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8498 so that we don't use the F_RELFLG which make the linker complain
8499 that somebody has stripped the relocation info.
8501 Also, the AIX ld program require that the relocation table
8502 is sorted by r_vaddr like the standard ATT assembler does.
8504 [he also changed the sizeof(struct ...)'s into the coff
8505 style FOOSZ macros. I'm not sure this is right, but I can't
8506 remember why. xoxorich.]
8508 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8510 * Makefile.in, configure.in, doc: use the doc. Build it, install
8513 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8515 * read.c: white space and comments only.
8517 * configure.in: use the new atof-ns32.c for ns32k.
8519 * write.c: comment change only.
8521 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8522 aren't yet integrated.
8524 * tc-i860.[hc]: blew off the dust. Something must still be done
8525 about conflicting relocation types.
8527 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8530 * tc-i960.c, tc-sparc.c: white space and comments only.
8532 * tc-a29k.h: delete duplicate macro definition.
8534 * new file atof-ns32k.c copied from hack's last unreleased gas.
8536 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8538 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8541 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8542 ChangeLog's prior to this are sketchy at best. I have logs.
8543 They just aren't ChangeLogs.
8550 version-control: never
