14 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
17 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
18 processing if add_symbol is undefined or in expr_section.

20 constant-valued symbol, convert to O_symbol and re-reduce.
21 (S_GET_VALUE): If symbol needs resolving, resolve it.
22 (indent_level): No longer static.
23 (print_symbol_value_1): Don't print frag address if it matches
24 zero_address_frag. Don't print "resolving" if already resolved.
25 Print segment name. Don't call print_expr_1 on an undefined
27 (print_expr_1): Fix whitespace before printing X_add_number.
29 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
30 not symbol_new, for symbols holding expression values.
31 * expr.h (make_expr_symbol): Move declaration here.
32 * write.c (fix_new_exp): Handle O_add by creating an
33 expression-valued symbol, and calling fix_new_exp recursively.
34 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
35 undefined symbol and a constant, fold the constant into the fixup,
36 and refer to the undefined symbol directly. Then process the
37 fixup again from scratch.
38 (write_object_file): Before calling adjust_reloc_syms, make a pass
39 through the symbol list trying to resolve values.
41 * write.c (print_fixup): New routine, for debugging.

49 * Makefile.in (gasp.o): Depends upon config.h.
51 * config/tc-mips.c: Include subsegs.h.
52 (md_apply_fix): If an unconditional b or bal overflows, and we are
53 not assembling PIC code, replace it with a j or jal.
55 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
56 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
58 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
60 * write.c (write_relocs): Add file name and line number to
61 as_fatal calls. Handle bfd_reloc_overflow case specifically when
62 RELOC_EXPANSION_POSSIBLE.
64 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
66 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
67 here. Use them for deciding which PRINTF*LIKE macro definitions
69 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
70 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
71 default definitions matching what we were doing before.
72 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
73 always use the varargs form if not using stdarg. It's safe to
74 always use vfprintf, because libiberty will provide it if the
75 native system doesn't. Also, always make format be const.
76 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
78 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
80 * config/tc-mips.c (load_register): Always use addiu when adding a
81 constant to $zero--no need to use daddiu.
82 (macro): Hack the -mips3 overflow tests to not fail when offsetT
85 * symbols.h (copy_symbol_attributes): Declare.
87 Thu Sep 22 21:58:24 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

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

111 * symbols.c (copy_symbol_attributes): New function. Copies BFD
112 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
113 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
114 zero. Don't call obj_frob_forward_symbol.

123 md_estimate_size_before_relax, md_ri_to_chars,
124 md_create_short_jump, md_create_long_jump.
125 (brtab_emit): Use data_section, not SEG_DATA.
127 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
129 * config/vms-conf.h: new file, manually derived from conf.in.
130 * config-gas.com: use it, and eliminate obsolete "host.h".
132 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
134 * config/tc-ppc.c (ppc_current_block): New static variable.
135 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

139 (ppc_es): Clear ppc_current_block.
140 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
141 from the csect of the enclosing block.
143 * config/tc-mips.c (insns_since_cache_access): Remove.
144 (append_insn): Remove setting of insns_since_cache_access, and
145 special 4600 handling; it turns out not to be required.
147 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
149 * config/tc-mips.c (md_shortopts): Remove E.
150 (md_longopts): Add EB and EL.
151 (md_parse_option): Handle -EB and -EL as separate options, rather
152 than as a single -E option with an argument.
154 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
156 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
157 involving global symbols too.
159 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
161 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
163 * configure.in: Test for remove, not delete. Fix cross-assembler
165 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
168 * read.c (pseudo_set, case O_symbol): If
169 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
170 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.

175 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
176 many others): new macros; values obtained from "DSTRECRDS.SDL".
177 * config/obj-vms.h (various): use them.
178 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
179 representation (only enum bitfields can avoid being bitstrings).
180 (bitfield_suffix, setup_basic_type): new routines.
181 (VMS_typedef_parse): use them. Now recognize bitfields of all
182 integral types, not just type `int'. Caveat: the representation
183 used for bitfields still does not work for objects placed in
184 registers, and gcc's optimizer sometimes puts small structs there.
186 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
188 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
190 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
191 (tc_frob_label): define this to call vms_check_for_special_label,
192 and declare the latter.
193 * config/obj-vms.c (vax_g_doubles): declare this file-scope
195 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
196 (vms_check_for_special_label): new routine (tc_frob_label).
197 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
198 and `gcc2_compiled.' labels; they won't reach here any more.
199 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
200 double', use `vax_g_doubles' flag to select type of double.
201 (VMS_write_object_file) [traceback setup]: don't pass symbols
202 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
203 and TBT_Routine_End functions.
205 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
207 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
208 S_GET_VALUE() to avoid many repeated function calls.
209 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
210 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
211 gets requested. [All the HACK_DEC_C_STARTUP code appears to
212 be obsolete; gcc does it automatically for vms target. It's
213 also misnamed, because it is for the "VAX C" run-time library,
214 not the newer "DEC C" one which has much different startup code.]
215 {various}: use `S_SET_xxx(symbol,new_value)' rather than
216 `S_GET_xxx(symbol) = new_value'.
218 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
220 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,

225 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
227 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
229 * expr.c (expr): Don't reduce the difference of two symbols in the
230 same frag if the symbols are not in normal sections.
232 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
233 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
234 (obj_attach_unwind_info): Do not define. Not needed anymore.
235 * config/tc-hppa.c: Delete whitespace at EOL.
236 (struct hppa_fix_struct): Delete fx_unwind field and all references.
237 (fix_new_hppa): Last arg is now a pointer to an int. Do not
238 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
239 fixups, store 32bits of unwind information in the fx_addnumber
241 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
242 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
243 pointer to 32 bits of unwind info.
244 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
245 pointer to the dummy symbol; set the addend field to fx_addnumber.
246 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
247 rather than &bfd_XXX_section.
249 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
251 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
252 value by one; discard adjustments previously being made. From
255 VMS- and Vax-related changes from Pat Rankin:
256 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
257 * vmsconf.sh: no longer have make-gas.com echo text about needing
258 to modify the gcc-vms driver when intending to use with gcc 1.x.
259 * as.c (parse_options): suppress 'v' from std_short_options and
260 eliminate VMS-specific conditional initialization;
261 [default case]: check for '-v' if md_parse_options doesn't recognize
263 [default case, #if VMS]: check for filename argument when '-v' seen;
265 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
266 for O_big literal operands (double floats and long long ints);
267 [VMS, md_shortopts]: add second colon after 'v';
268 (md_parse_options) [VMS, case 'v']: check for argument, so
269 caller can handle `-v' w/o arg.

320 Update for autoconf 1.118:
321 * gdbinit.in: New file, created from old .gdbinit.
323 * aclocal.m4 (GAS_GDBINIT): Deleted.
324 * configure.in: Don't use it. Instead, generate .gdbinit from
325 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
326 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
327 to ensure that older versions of autoconf aren't used.
328 * Makefile.in: Added @configure_input@ line.

382 disp_reloc field to reloc() function, and use TC_RELOC to generate
383 value to pass to fix_new_exp.

416 st_Global. Don't set the index of an external st_Proc or
417 st_StaticProc symbol unless it is also a local symbol.
419 * read.c (read_a_source_file): The second argument to as_where is
420 unsigned int *, not int *.
422 Thu Sep 8 17:18:24 1994 Kung Hsu (kung@mexican.cygnus.com)
424 * config/obj-ecoff.h : Change names to OBJ_GENERATE_ASM_LINENO,
425 and generate_asm_lineno.
426 * config/obj-elf.h : ditto.
428 * read.c (read_a_source_file): if no file when inst is read, set

460 * Makefile.in (CC_FOR_TARGET, NM_FOR_TARGET, OBJDUMP_FOR_TARGET,
461 install, uninstall): Don't use "brokensed" hack any more, the new

464 Update for autoconf beta 1.112:
465 * aclocal.m4 (GAS_CHECK_DECL_NEEDED, GAS_WORKING_ASSERT): New
467 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
468 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
469 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
470 message to try to ease confusion about autoconf's

1312 (control_regs): New pointer.
1313 (m68k_ip): Use control_regs instead of testing CPU every time.

1894 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
1895 and -many (all architectures).
1897 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1906 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
1908 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
1909 branch with an instruction that uses $at, in case the branch is
1911 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
1912 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
1913 to make it pcrel_offset.
1914 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
1915 reloc->address; another gruesome hack to get gas reloc handling to
1918 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1920 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
1923 (emit_insn): New function.
1924 (md_assemble): Call it.
1925 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
1927 (lituse_pending): New variable. Set by anything that generates a
1928 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
1929 tested by code that might want to emit a LITUSE reloc.
1930 (emit_unaligned_io): New function. Currently calls md_assemble,
1931 but it should eventually be converted to generate the insn itself
1932 and call emit_insn directly.
1933 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
1934 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
1935 emit_bis_r): Likewise.

1944 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1946 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
1947 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
1948 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

1960 * config/tc-mips.c (enum mips_pic_level): New enum.
1961 (mips_pic): Change from int to enum mips_pic_level. Change all

1963 (load_address): Handle EMBEDDED_PIC.
1964 (macro): Handle EMBEDDED_PIC in all PIC cases.
1965 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
1966 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
1967 -non_shared to use NO_PIC (this is how the Irix 5 assembler
1968 works). Do not permit -G with SVR4_PIC.
1969 (s_abicalls): Warn if -G was used, and force -G 0.
1970 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
1971 anything but a.out, not just for ELF. For ECOFF, don't generate a
1972 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
1974 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
1976 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1978 * config/tc-hppa.c (create_new_space): Use ints, not chars as
1979 parameters to avoid losing when compiling with HP CC.
1980 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
1982 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1984 * Makefile.in (config-stamp): If `defs' is defined, emit a
1985 preprocessor directive to create a macro named by this value into
1986 config.new; don't explicitly go for BFD_ASSEMBLER.
1987 * configure.in: Define `defs', not `BFDDEF'. Set it to
1988 MANY_SEGMENTS for any obj-coffbfd target.
1989 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
1990 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
1992 (LOCAL_LOADLIBES): Deleted.
1993 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
1994 * config/m88kcoff.mt (TDEFINES): Ditto.

2020 bfd_set_symtab is called.
2021 (dump_section_relocs): Note whether a symbol is a section symbol
2023 (adjust_reloc_syms): For now, always supply an absolute symbol for
2024 fixups without symbols but not yet `done'. Use section_symbol to
2025 get the symbol, instead of going directly for abs_symbol.
2026 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2027 reloc is not a section symbol and is not in the symbol table.
2028 (set_symtab): New function, broken out from write_object_file.
2029 Counts symbol table instead of relying on an earlier count.
2030 (write_object_file): Call set_symtab, but do it after potentially
2031 invoking the *_frob_file macros. Don't bother counting symbols.
2032 Call symbol_remove, instead of expanding it in place. Moved the
2033 conditionalized `object_file_size' declaration down to
2034 conditionalized block where it's used. When using the absolute
2035 symbol for a fixup without a symbol, set sy_used_in_reloc.
2036 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2037 the correct symbol for the absolute section.
2039 * subsegs.c (section_symbol): Use symbol_new instead of
2040 symbol_make, since we may want it to go into the symbol table.
2041 Make the new symbol have internal linkage. If
2042 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2043 symbol with the newly created GAS symbol.
2044 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2045 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2052 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2053 (sparc_ip, label "immediate"): Reject constants for pcrel
2054 instructions only if the relocation type indicates a "call"
2055 instruction and the offset is within range of a "jmpl %g0". If
2056 it's not in range, use the absolute section symbol plus an offset.
2057 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2059 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2061 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2064 * configure.in: Eliminated all targets using obj-coff but not
2065 defining BFD_ASSEMBLER; I think all such targets that are
2066 supported will be matched by real CPU-OS combinations earlier in
2068 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2069 some comments about the dpx2 configuration, but left it disabled,
2070 since it couldn't be reached before.
2071 (target a29k-amd-ebmonold): Deleted.
2073 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2081 the 'j' operand if there are no further alternatives for this
2084 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2085 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2086 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2088 * config/tc-mips.c (mips_align): Take new argument, label, and use
2089 it instead of global insn_label.
2090 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2091 call to mips_emit_delay and pass it to mips_align.
2093 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2095 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2097 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2098 argument to a .callinfo directive. Don't loop forever on errors.
2100 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2101 use pre-defined registers as arguments.

2106 S_IS_EXTERNAL when deciding whether to discard a symbol.
2108 * config-gas.com: Scan Makefile.in, not version.c, for current
2109 version number. Delete all versions of temp files when finished
2110 with them. Create config.h.
2112 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2113 values to reduce number of lookups with S_GET_VALUE. Skip debug
2114 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2115 holger@botbso.rhein-main.de.)
2116 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2117 field. (Also from Holger Teutsch.) Watch for a would-be register
2118 mask that spans frags.
2120 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2121 this_base, not line_base. (Patch from Andreas Arens,

2124 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2125 look local if they're exported or undefined. Used to be done for
2128 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2129 Get it from the looked-up symbol, instead of using the string from
2130 the input stream, which is no longer null-terminated.
2131 (LEX_PCT): New macro, defaults to 0.
2132 (lex_type): Use it for `%'.
2134 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2184 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2185 0xffff for 'j' to be compatible with MIPS assembler. These

4255 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4257 * configure.in: Set bfd_gas for all sparc targets. Added facility
4258 for keeping or rejecting configurations still under development;
4259 default is to assume production environment, and reject configs
4260 still being worked on. Mark Elf configurations (except sparc and
4261 i386) as developmental. Deleted cases matching some generic names
4262 in favor of more specific names. (E.g., when we get Alpha

4280 for functions only used within tc-hppa.c, likewise for structures,
4281 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4282 conditional code in a few small places.
4284 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4285 structures, global variables, forward declarations together.

4287 conditional code -- try to group conditional code together
4288 into a few places. Make all functions and variables which
4289 are only used within tc-hppa.c static. PARAMize all functions.
4290 Add comments to functions. Delete unused functions, variables,
4291 #defines, etc. Delete unused members within structures. Delete
4292 ldil;ble hacks -- it is believed they were installed to work
4293 around old gas bugs. Avoid using mixed case for local
4294 functions, variables, and structures. Fix formatting problems
4295 not found by GNU-indent. Add FIXME notices for things which
4296 should be worked on the near future. Delete lots of old
4297 useless (1.36 PA-SOM) code.

4311 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
4312 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
4314 * config/tc-hppa.c: Likewise.
4316 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
4317 of elf32_symbol_type.
4318 (pa_export_args): Likewise.
4319 (elf_hppa_final_processing): Likewise.

4326 a multiple of the section alignment rather than always a
4329 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4330 bits are zero (eg they specify no relocations), then do not even
4331 bother adding their entries to thesymextn section.

4372 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
4373 call strchr for each character to see if it is a special char,
4374 instead add a second loop over special_chars. Set alignment
4375 of text, data and bss sections to 4.
4376 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4378 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4379 ELF, since the ELF object format does not have these type of
4380 relocations. Change the abort into as as_bad and return
4381 BFD_RELOC_NONE to silence compiler warnings.
4382 (md_assemble): Keep track of the instruction size. Allow white
4383 space between the $ and the constant for compatibility with older
4384 gases and other assemblers.

6768 a29k .bss section; the mondfe program doesn't like it.

6789 source directory, if that's not the current directory.
6791 * configure.in (per-host): Accept MIPS host with BSD version

6817 avoid some redefinition complaints on some systems.
6818 (const, volatile): Don't need these conditionally defined if we
6819 use CONST and VOLATILE from ansidecl.h.
6820 (seg_name): Use CONST, not const.

6824 * config/tc-mips.c: Reindented to GNU standards.
6826 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
6828 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
6829 (fixup_segment): Add a29k special case; the linker is not prepared
6830 to see a segment offset here.
6832 * app.c (do_scrub_next_char): Added new state, 10, modifying state

6835 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
6837 * Makefile.in: add dvi target; as-$(config).texinfo might live in
6838 srcdir, might be in objdir.
6840 * doc/Makefile.in: dvi depends on as.dvi

6868 dropping a space immediately following an identifier.
6869 * expr.c, write.c: Rewrote assert expressions to not use multiple
6870 lines; I don't think that can be done portably.
6871 * config/tc-mips.c (macro): Use $AT if target register is zero in
6872 load instruction, which it can be for a floating point load.

6885 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
6886 z8k-opc.h, not z8k.h.
6888 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
6891 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

6946 prototypes for all static functions. Moved existing minimal
6947 debugging format support info #ifndef OBJ_ECOFF blocks.

6996 * make-gas.com: Find obstack.obj if it's not in the current
6998 * read.c (s_ignore): Don't declare is_end_of_line. It's
6999 redundant, and triggers a VMS gcc compiler bug.
7001 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7002 current segment as an argument. (Ignored in all cases but VMS.)
7003 All callers and definitions changed.
7005 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)

7330 * expr.c (operand): If character other than comma or newline is a
7331 logical end-of-line character, use the newline case.
7332 From Eric Youngdale:
7333 (operand): Set X_add_number field for floating-point numbers.
7334 (operand): Treat zero byte as end-of-operand.
7336 * configure.in (per-target): Look for with_bfd_assembler option.
7337 For now, only accept "no", until the merge is done.
7339 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7340 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

7346 * expr.c: Add "const" modifier to hex_value.
7347 * symbols.c: Finish conversion to S_* macros in the VMS only

7349 md_[long,short]_jump_size. Remove declaration of const_flag
7350 (which will be declared in obj-vms.h).
7351 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7352 Fix arguments to VMS_write_object_file.
7353 * config-gas.com: New file. Script for VMS systems to set up the
7354 configuration to build gas for VMS, and create config.status.
7355 * make-gas.com: Redone to work with new scheme.
7356 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
7358 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
7359 will swap bytes if needed on a big endian system. Use throughout
7361 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7362 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7363 types of malformed stabs. Change parsing algorithm so that we are
7364 more certain of having all of the information that we need on hand.
7365 * obj-vms.c (final_forward_reference): New function, used to help
7366 resolve the data types of as many struct elements as possible

7384 SEG_DATA or SEG_E1 if needed.
7385 (s_lcomm): Likewise with bss_section.
7386 (s_fill): Use memset, not bzero.
7388 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

7410 (big_section, reg_section, pass1_section, diff_section,
7411 absent_section, text_section, data_section, bss_section): If
7412 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7413 mapping to segT enum values.
7414 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7415 if these are used or defined, if BFD_ASSEMBLER.
7416 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7417 subseg_new split into two functions.
7418 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7420 * as.h (volatile): Don't define if already defined.
7421 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7423 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7424 declare with format attribute for -Wformat checking.
7426 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7428 * app.c, config/tc-*.c: Don't include read.h, since it is already
7431 * These are based on patches from Minh Tran-le
7432 <mtranle@paris.intellicorp.com>.
7433 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7434 obj_format coffbfd and gas_target i386coff for target.

7436 * config/i386aix.mt: Removed (no longer used).
7437 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7439 (LDFLAGS): Added, defined as -shlib.
7440 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7441 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7442 (DOT_LABEL_PREFIX): Define.
7443 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7444 name rather than L0\001.
7445 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7447 * symbols.c, symbols.h (local_bss_counter): Removed.
7448 * write.c (write_object_file): bss no longer uses
7449 local_bss_counter. Pass correct data and bss size to
7450 VMS_write_object_file.
7451 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
7452 argument, rather than using local_bss_counter.

7456 (size_section): Restored sanity check.
7457 (do_relocs_for): Base section address on s_paddr rather than
7458 computing it. Adjust a29k R_IHIHALF special case to account for
7459 section paddr (used to require paddr to be zero). If there are no
7460 reclos, set s_relptr to 0. Set relocation size in object_headers.
7461 (fill_section): Always set s_vaddr here, removing
7462 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7463 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.

7468 H_{SET,GET}_* macros.
7469 (do_linenos_for): Set lineno size in object_headers.
7470 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7471 set s_vaddr here. If string_byte_count remains 4, set it back to
7472 0, and only write strings out if there are some. Call
7473 fill_section before do_relocs_for and do_linenos_for.
7474 (obj_coff_section): Handle optional quoted second argument giving
7475 section characteristics.

7503 * config/obj-coff.h: Don't use #elif.
7505 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

7545 (yank_symbols): Don't merge labels.
7546 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7692 could be doing emulation.
7694 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7697 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

7767 * Support for i386-sysv.
7768 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7806 * tc-z8k.c: lots of bug fixes
7808 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7810 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7811 #elif, since it is not supported by old compilers.
7812 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7813 couple of expressions in tc-m68k.c.
7815 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

7841 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7843 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7844 sections starting from zero, rather than making them consecutive.
7845 This makes subsequent reloc calculations easier, esp if the object
7846 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7847 allocate lcomm in .data rather than in .bss. It seems that some
7848 tools can't cope with a non-zero sized bss before linkage.

7871 * Makefile.in (install): if $(tooldir) exists, install as in
7874 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7876 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7877 .word is < -32768 or > 32767. The -J flag causes the error to be
7878 ignored. This is to catch over-sized switches generated by gcc on
7879 systems which don't support the broken .word hack.
7880 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7881 write.c (fixup_segment): check for signed .word overflow if
7882 WARN_SIGNED_OVERFLOW_WORD.

7901 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
7903 * input-scrub.c (input_scrub_push): call input_file_begin, not
7905 messages.c (as_perror): print ": " between the passed in error and
7906 the strerror, like perror does.
7908 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
7910 * Makefile.in: use gas_target instead of modifying target_cpu.
7911 From Steve Chamberlain:
7912 Makefile.in: Handle m68*-*-coff*.
7913 read.c, read.h: add mult argument to s_space
7915 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
7916 Motorola and MIT syntax; gas can now assemble either type of

7922 (size_section) removed bad sanity check
7923 (fill_section) added rs_machine_dependent case
7924 (write_object_file) call fixup_mdeps
7925 (fixup_segment) set fx_subsy to 0.
7926 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
7928 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
7931 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7933 * Makefile.in (LIBS): Include opcode library.
7935 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

7955 tc-i960.c (md_ri_to_chars): Always output bout object file in
7956 little endian byte order (used to use endianness of host).
7958 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7960 * config/tc-m68k.c (init_table): Now const. Always include 68851
7961 data, so that "bc" is available to 68040 cache instructions.
7962 Added "tt0", "tt1", and 68ec030 variants.
7963 (md_assemble): Complain if 68000 (only) and 68881 are specified.
7964 (enum _register): Added TT0, TT1.

7996 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
7998 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
7999 written with indirection on the last two operands, which can be
8000 either data or address registers. Added a new operand type 'r'
8001 which accepts either register type. Added '(' to notend stuff in
8002 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8114 characteristics have been), default to 68020. Don't need extra
8115 quotes around error string.

8197 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
8199 * write.c (write_object_file): keep the fix_tail clean, which
8200 fixes a bug in -R where relocations were being lost.
8202 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
8204 * configure.in: recognize m680x0 as having sun3 emulation mode for

8248 * write.c (write_object_file): For b.out format, round up section
8249 start addresses to match required alignment.
8251 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8253 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8254 where gcc looks for it.
8256 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
8258 * Makefile.in: Changed some lines to be less confusing for some

8328 * expr.c (operand): if can't work out what sort of operand it is,
8329 then look through FLT_CHARS for a hint.
8331 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8333 * Makefile.in, configure.in: removed traces of namesubdir,

8337 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8338 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8339 copyrights to '92, changed some from Cygnus to FSF.
8341 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8343 * expr.c: If an expression is single comma, then return with
8344 SEG_ABSENT rather than an error - since the sparc front end does
8345 really strange things with things like fbge,a
8347 * as.h: include bfd.h if using many sections
8348 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8349 local labels didn't work.
8350 * listing.c (list_symbol_table): don't core dump when there's no
8352 * write.c, write.h: call fix_new with the right number of args on
8354 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8357 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8359 * app.c: MRI compatibility - allow single quote to start a string.
8360 * as.c: fix typo recently introduced.
8361 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8362 * expr.c: Much rewriting, to accomodate MRI syntax for
8363 expressions. Also easier to read now.
8364 * listing.c: Put back defuns
8365 * read.c: modified to accept MRI syntax, put back listing pseudo
8366 ops so that an assembler built with NO_LISTING ignores list ops
8368 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8369 machine is a SPARC or a 29K.
8370 * config/obj-aout.c: added s_sect pseudo op
8371 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8372 fill in the timestamp.
8373 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8374 anymore, define all the relocs which the tc-<x> bit will use so we
8375 can translate from them to the coff types.
8376 * config/tc-a29k.c: reloc_type isn't ane enum any more
8377 * config/tc-m68k.c: Added NO_RELOC definition.
8379 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8381 * Makefile.in: put header files before C source for TAGS; remove
8382 references to non-existent syscalls.h.
8384 * read.c, write.c subsegs.c: back out the .bss changes.
8386 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8388 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8392 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8394 * symbols.c (local_label_name): symbols now start with ^A.
8396 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8397 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8398 generate these sections. .align: will use NOP_OPCODE or 0
8399 for padding. This is just for being nice to the
8402 * expr.c (operand): changed to generate local label "\001L0"
8403 starting with a ^A so that it is recognized as a local label.
8405 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8407 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8408 i/o opcodes - inb, inw, outb and outw. string manipulation with
8409 att syntax - scmp, slod, smov, ssca, ssto.
8411 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8412 to just after .file .
8414 In obj_crawl_symbol_chain() where it tries to put the external
8415 symbols apart, with the condition:
8416 (!S_IS_DEFINED(symbolP) &&
8417 !S_IS_DEBUG(symbolP) &&
8418 !SF_GET_STATICS(symbolP))
8419 it was moving too many symbols out. So I switch it back to the
8421 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8423 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8424 so that we don't use the F_RELFLG which make the linker complain
8425 that somebody has stripped the relocation info.
8427 Also, the AIX ld program require that the relocation table
8428 is sorted by r_vaddr like the standard ATT assembler does.
8430 [he also changed the sizeof(struct ...)'s into the coff
8431 style FOOSZ macros. I'm not sure this is right, but I can't
8432 remember why. xoxorich.]
8434 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8436 * Makefile.in, configure.in, doc: use the doc. Build it, install

8441 * read.c: white space and comments only.
8443 * configure.in: use the new atof-ns32.c for ns32k.
8445 * write.c: comment change only.
8447 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8448 aren't yet integrated.
8450 * tc-i860.[hc]: blew off the dust. Something must still be done
8451 about conflicting relocation types.
8453 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8456 * tc-i960.c, tc-sparc.c: white space and comments only.
8458 * tc-a29k.h: delete duplicate macro definition.
8460 * new file atof-ns32k.c copied from hack's last unreleased gas.
8462 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
