3 * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New
4 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF

8 (reloc): Always permit return of 8- and 16-bit relocation types.
9 Add a space after "pc-relative" in the error message.
10 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
11 BFD_RELOC_386_GOTOFF relocs.

22 referring to PLT entries.
23 * write.c (fix_new_internal): Initialize fx_plt to zero.
24 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
25 Don't adjust fx_offset by frag address, since S_GET_VALUE now
26 includes the frag address.
27 (fixup_segment): Changed local var PCREL to type int, added PLT.
28 If PC-relative fixup refers to a PLT entry for a symbol in the
29 current section, don't reduce it.
31 * write.c (adjust_reloc_syms): Exit loop through a label. If
32 DEBUG5 is defined, print out each fixup before and after
34 (fixup_segment): If DEBUG5 is defined, print out each fixup before
36 (print_fixup): Added prototype. Show address on first line. Show
37 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

61 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
64 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
65 processing if add_symbol is undefined or in expr_section.
66 (resolve_symbol_value, case O_add): For symbol plus

70 (print_symbol_value_1): Don't print frag address if it matches
71 zero_address_frag. Don't print "resolving" if already resolved.
72 Print segment name. Don't call print_expr_1 on an undefined
74 (print_expr_1): Fix whitespace before printing X_add_number.
76 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
77 not symbol_new, for symbols holding expression values.
78 * expr.h (make_expr_symbol): Move declaration here.
79 * write.c (fix_new_exp): Handle O_add by creating an
80 expression-valued symbol, and calling fix_new_exp recursively.
81 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
82 undefined symbol and a constant, fold the constant into the fixup,
83 and refer to the undefined symbol directly. Then process the
84 fixup again from scratch.
85 (write_object_file): Before calling adjust_reloc_syms, make a pass
86 through the symbol list trying to resolve values.
88 * write.c (print_fixup): New routine, for debugging.
89 (write_relocs): Call bfd_install_relocation. Deleted various
90 hacks for working around problems with bfd_perform_relocation.

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

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

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

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

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

186 (ppc_es): Clear ppc_current_block.
187 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
188 from the csect of the enclosing block.
190 * config/tc-mips.c (insns_since_cache_access): Remove.
191 (append_insn): Remove setting of insns_since_cache_access, and
192 special 4600 handling; it turns out not to be required.

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

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

267 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
268 not &bfd_abs_section.

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

368 * gdbinit.in: New file, created from old .gdbinit.
370 * aclocal.m4 (GAS_GDBINIT): Deleted.
371 * configure.in: Don't use it. Instead, generate .gdbinit from
372 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,

426 fixup is not local, to prevent relocations against externals from
428 (md_assemble): Initialize disp_reloc field to NO_RELOC. Pass
429 disp_reloc field to reloc() function, and use TC_RELOC to generate
430 value to pass to fix_new_exp.
431 (md_assemble): Change 32-bit reloc against GOT_symbol into a GOTPC
433 (i386_operand): Initialize disp_reloc field to NO_RELOC. Handle

464 st_StaticProc symbol unless it is also a local symbol.
466 * read.c (read_a_source_file): The second argument to as_where is
467 unsigned int *, not int *.

1432 VMS debugger now recognizes `long long' variables correctly.
1433 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1434 for gcc2's predefined types "long double" (same as double, as
1435 per gcc's current state), "long long int", "long long unsigned
1436 int", and final `otherwise' case (to avoid uninitialized type
1437 and size fields). [caveat: predefined types "complex int",
1438 "complex float", "complex double", and "complex long double" are
1441 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
1442 of 0, because the latter indicates success rather than failure

1807 directory, and specify PSECT attributes explicitly to linker.
1808 Also added missing label.

1898 don't spew remainder of input file in error message.
1899 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
1900 message with reloc type and try to process remainder of file.

1912 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
1913 flag rather than signedp field. Only permit extended range if
1914 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
1915 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
1917 * config/tc-ppc.c (ppc_size): New static variable.
1918 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
1919 (md_begin): If an instruction has a size specific flag set, only
1920 add it if we are assembling that size.

1924 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
1925 cross section PC relative relocs right for COFF and ELF.
1927 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

1953 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
1955 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
1956 branch with an instruction that uses $at, in case the branch is
1958 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
1959 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
1960 to make it pcrel_offset.
1961 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
1962 reloc->address; another gruesome hack to get gas reloc handling to

1967 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
1970 (emit_insn): New function.
1971 (md_assemble): Call it.
1972 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
1974 (lituse_pending): New variable. Set by anything that generates a
1975 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
1976 tested by code that might want to emit a LITUSE reloc.
1977 (emit_unaligned_io): New function. Currently calls md_assemble,
1978 but it should eventually be converted to generate the insn itself
1979 and call emit_insn directly.
1980 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
1981 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
1982 emit_bis_r): Likewise.

1991 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1993 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
1994 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
1995 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2010 (load_address): Handle EMBEDDED_PIC.
2011 (macro): Handle EMBEDDED_PIC in all PIC cases.
2012 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2013 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2014 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2015 works). Do not permit -G with SVR4_PIC.
2016 (s_abicalls): Warn if -G was used, and force -G 0.
2017 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2018 anything but a.out, not just for ELF. For ECOFF, don't generate a
2019 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2021 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2023 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2025 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2026 parameters to avoid losing when compiling with HP CC.
2027 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2029 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2031 * Makefile.in (config-stamp): If `defs' is defined, emit a
2032 preprocessor directive to create a macro named by this value into
2033 config.new; don't explicitly go for BFD_ASSEMBLER.
2034 * configure.in: Define `defs', not `BFDDEF'. Set it to
2035 MANY_SEGMENTS for any obj-coffbfd target.
2036 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2037 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2039 (LOCAL_LOADLIBES): Deleted.
2040 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2041 * config/m88kcoff.mt (TDEFINES): Ditto.

2067 bfd_set_symtab is called.
2068 (dump_section_relocs): Note whether a symbol is a section symbol
2070 (adjust_reloc_syms): For now, always supply an absolute symbol for
2071 fixups without symbols but not yet `done'. Use section_symbol to
2072 get the symbol, instead of going directly for abs_symbol.
2073 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2074 reloc is not a section symbol and is not in the symbol table.
2075 (set_symtab): New function, broken out from write_object_file.
2076 Counts symbol table instead of relying on an earlier count.
2077 (write_object_file): Call set_symtab, but do it after potentially
2078 invoking the *_frob_file macros. Don't bother counting symbols.
2079 Call symbol_remove, instead of expanding it in place. Moved the
2080 conditionalized `object_file_size' declaration down to
2081 conditionalized block where it's used. When using the absolute
2082 symbol for a fixup without a symbol, set sy_used_in_reloc.
2083 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2084 the correct symbol for the absolute section.
2086 * subsegs.c (section_symbol): Use symbol_new instead of
2087 symbol_make, since we may want it to go into the symbol table.
2088 Make the new symbol have internal linkage. If
2089 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2090 symbol with the newly created GAS symbol.
2091 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2092 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2097 (in_signed_range): New function.
2099 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2100 (sparc_ip, label "immediate"): Reject constants for pcrel
2101 instructions only if the relocation type indicates a "call"
2102 instruction and the offset is within range of a "jmpl %g0". If
2103 it's not in range, use the absolute section symbol plus an offset.
2104 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2106 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2108 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2111 * configure.in: Eliminated all targets using obj-coff but not
2112 defining BFD_ASSEMBLER; I think all such targets that are
2113 supported will be matched by real CPU-OS combinations earlier in
2115 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2116 some comments about the dpx2 configuration, but left it disabled,
2117 since it couldn't be reached before.
2118 (target a29k-amd-ebmonold): Deleted.
2120 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2128 the 'j' operand if there are no further alternatives for this
2131 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2132 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2133 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2135 * config/tc-mips.c (mips_align): Take new argument, label, and use
2136 it instead of global insn_label.
2137 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2138 call to mips_emit_delay and pass it to mips_align.
2140 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2142 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

2153 S_IS_EXTERNAL when deciding whether to discard a symbol.
2155 * config-gas.com: Scan Makefile.in, not version.c, for current
2156 version number. Delete all versions of temp files when finished
2157 with them. Create config.h.

2160 values to reduce number of lookups with S_GET_VALUE. Skip debug
2161 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2162 holger@botbso.rhein-main.de.)
2163 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2164 field. (Also from Holger Teutsch.) Watch for a would-be register
2165 mask that spans frags.
2167 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2168 this_base, not line_base. (Patch from Andreas Arens,
2169 ari@obelix.av.rwth-aachen.de.)
2171 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2172 look local if they're exported or undefined. Used to be done for
2175 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2176 Get it from the looked-up symbol, instead of using the string from
2177 the input stream, which is no longer null-terminated.
2178 (LEX_PCT): New macro, defaults to 0.
2179 (lex_type): Use it for `%'.
2181 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2231 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2232 0xffff for 'j' to be compatible with MIPS assembler. These

2249 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

4304 * configure.in: Set bfd_gas for all sparc targets. Added facility
4305 for keeping or rejecting configurations still under development;
4306 default is to assume production environment, and reject configs
4307 still being worked on. Mark Elf configurations (except sparc and
4308 i386) as developmental. Deleted cases matching some generic names
4309 in favor of more specific names. (E.g., when we get Alpha

4335 into a few places. Make all functions and variables which
4336 are only used within tc-hppa.c static. PARAMize all functions.
4337 Add comments to functions. Delete unused functions, variables,
4338 #defines, etc. Delete unused members within structures. Delete
4339 ldil;ble hacks -- it is believed they were installed to work
4340 around old gas bugs. Avoid using mixed case for local
4341 functions, variables, and structures. Fix formatting problems
4342 not found by GNU-indent. Add FIXME notices for things which
4343 should be worked on the near future. Delete lots of old
4344 useless (1.36 PA-SOM) code.

4363 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
4364 of elf32_symbol_type.
4365 (pa_export_args): Likewise.

4373 a multiple of the section alignment rather than always a
4376 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4377 bits are zero (eg they specify no relocations), then do not even
4378 bother adding their entries to thesymextn section.

4423 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4425 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4426 ELF, since the ELF object format does not have these type of
4427 relocations. Change the abort into as as_bad and return
4428 BFD_RELOC_NONE to silence compiler warnings.
4429 (md_assemble): Keep track of the instruction size. Allow white
4430 space between the $ and the constant for compatibility with older
4431 gases and other assemblers.

6875 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

6882 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

6915 dropping a space immediately following an identifier.

6917 lines; I don't think that can be done portably.
6918 * config/tc-mips.c (macro): Use $AT if target register is zero in

7043 * make-gas.com: Find obstack.obj if it's not in the current
7045 * read.c (s_ignore): Don't declare is_end_of_line. It's
7046 redundant, and triggers a VMS gcc compiler bug.

7108 (zero_address_frag, bss_address_frag): Now initialized at run
7110 * as.c (main): Call frag_init.

7381 (operand): Treat zero byte as end-of-operand.
7383 * configure.in (per-target): Look for with_bfd_assembler option.
7384 For now, only accept "no", until the merge is done.
7386 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7387 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

7393 * expr.c: Add "const" modifier to hex_value.
7394 * symbols.c: Finish conversion to S_* macros in the VMS only
7395 parts of the program. Add "const" modifier to
7396 md_[long,short]_jump_size. Remove declaration of const_flag
7397 (which will be declared in obj-vms.h).
7398 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7399 Fix arguments to VMS_write_object_file.
7400 * config-gas.com: New file. Script for VMS systems to set up the

7462 if these are used or defined, if BFD_ASSEMBLER.
7463 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7464 subseg_new split into two functions.
7465 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7467 * as.h (volatile): Don't define if already defined.

7470 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7471 declare with format attribute for -Wformat checking.
7473 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7475 * app.c, config/tc-*.c: Don't include read.h, since it is already
7478 * These are based on patches from Minh Tran-le
7479 <mtranle@paris.intellicorp.com>.
7480 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7481 obj_format coffbfd and gas_target i386coff for target.
7482 (i[34]86-*-isc*): New host (uses sysv).
7483 * config/i386aix.mt: Removed (no longer used).
7484 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7486 (LDFLAGS): Added, defined as -shlib.
7487 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7488 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7489 (DOT_LABEL_PREFIX): Define.
7490 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7491 name rather than L0\001.
7492 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7494 * symbols.c, symbols.h (local_bss_counter): Removed.
7495 * write.c (write_object_file): bss no longer uses
7496 local_bss_counter. Pass correct data and bss size to
7497 VMS_write_object_file.
7498 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
7499 argument, rather than using local_bss_counter.

7503 (size_section): Restored sanity check.
7504 (do_relocs_for): Base section address on s_paddr rather than
7505 computing it. Adjust a29k R_IHIHALF special case to account for
7506 section paddr (used to require paddr to be zero). If there are no
7507 reclos, set s_relptr to 0. Set relocation size in object_headers.
7508 (fill_section): Always set s_vaddr here, removing
7509 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7510 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7511 Set STYP_INFO for .comment.
7512 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7513 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7515 H_{SET,GET}_* macros.
7516 (do_linenos_for): Set lineno size in object_headers.
7517 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7518 set s_vaddr here. If string_byte_count remains 4, set it back to
7519 0, and only write strings out if there are some. Call
7520 fill_section before do_relocs_for and do_linenos_for.
7521 (obj_coff_section): Handle optional quoted second argument giving
7522 section characteristics.
7523 (obj_coff_bss): Added to handle .bss.
7524 (obj_coff_ident): Added to handle .ident (puts string in .comment
7526 (obj_coff_lcomm): Put common symbols in .bss, not .data.
7527 (fixup_mdeps): Change to segment. Call frag_wane after
7529 (fixup_segment): Explicitly check S_IS_COMMON before making 386
7530 adjustment (already happened only for common symbols, but this is
7532 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
7533 * config/tc-i386.c (s_bss): Don't use if I386COFF.

7543 * app.c (app_push): Use memcpy, not bcopy.
7544 (do_scrub_next_char): For \", return " not '.
7545 (symbol_chars): Now const.
7547 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7548 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7550 * config/obj-coff.h: Don't use #elif.
7552 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7553 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

7579 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7580 using ZERO_BASED_SEGMENTS.
7581 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7582 never set segment address for SEG_E2 (.bss) and don't write out
7583 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7584 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7585 definitions, and don't merge tags with non-tags. Check for .bf
7586 rather than just checking whether the second character is b and
7587 the third character is f.
7588 (obj_coff_val): gcc can generate values which we don't handle
7589 correctly; discard information for now, since it only affects the
7590 debugging information.
7591 (tag_find_or_name): Don't insert tags in the symbol table.
7592 (yank_symbols): Don't merge labels.
7593 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7597 used in AT&T i386 syntax.
7598 (fixup_segment): Take segment as argument. On the i386, adjust PC
7599 relative addends by the segment vaddr.
7600 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
7601 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

7738 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
7739 could be doing emulation.
7741 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7744 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

7773 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7775 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
7776 constant will not fit in an immediate field.
7777 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

7812 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
7814 * Support for i386-sysv.
7815 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7839 * tc-m68k.c (get_num): make it work for all segments, not just the
7842 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
7844 * configure.in: recognize i386-*-bsd emulation.

7853 * tc-z8k.c: lots of bug fixes
7855 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7857 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7858 #elif, since it is not supported by old compilers.
7859 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7860 couple of expressions in tc-m68k.c.
7862 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7864 * read.c (cons): If NO_RELOC is defined, use it.
7866 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
7868 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
7870 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
7871 local labels to start with a .) and set REGISTER_PREFIX to %.
7872 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
7874 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
7876 * messages.c: Comment changes.
7878 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

7881 * messages.c: If __STDC__ is not defined, define NO_STDARG.
7883 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
7885 * listing.c (debugging_pseudo): Add stabs and stabn as things to
7888 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7890 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7891 sections starting from zero, rather than making them consecutive.
7892 This makes subsequent reloc calculations easier, esp if the object
7893 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7894 allocate lcomm in .data rather than in .bss. It seems that some
7895 tools can't cope with a non-zero sized bss before linkage.
7897 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7899 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
7900 throughout. That enum no longer means what we thought it meant.
7902 * tc-m68k.c (md_assemble, md_parse_option): Handle new
7903 "-mno-688[58]1" options.
7905 * tc-m68k.c: Added CPU32 support.
7907 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7909 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

7913 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
7914 Change LIBDEPS dependence to LIBS.
7916 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
7918 * Makefile.in (install): if $(tooldir) exists, install as in
7921 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7923 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7924 .word is < -32768 or > 32767. The -J flag causes the error to be
7925 ignored. This is to catch over-sized switches generated by gcc on
7926 systems which don't support the broken .word hack.
7927 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7928 write.c (fixup_segment): check for signed .word overflow if
7929 WARN_SIGNED_OVERFLOW_WORD.
7931 * write.c (fixup_segment): fixed missing parens in expression
7932 checking for byte or word overflow.
7934 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
7935 obj-coffbfd.c (fixup_segment): check for signed .word overflow if

7943 Support for i386 coff
7944 * obj-coffbfd.h : added stuff
7945 * tc-i386.c (tc_coff_fix2rtype): new function
7946 * tc-i386.h : new coff defines
7948 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
7950 * input-scrub.c (input_scrub_push): call input_file_begin, not

7962 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
7963 Motorola and MIT syntax; gas can now assemble either type of

8045 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8046 written with indirection on the last two operands, which can be
8047 either data or address registers. Added a new operand type 'r'
8048 which accepts either register type. Added '(' to notend stuff in
8049 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8388 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8390 * expr.c: If an expression is single comma, then return with
8391 SEG_ABSENT rather than an error - since the sparc front end does
8392 really strange things with things like fbge,a
8394 * as.h: include bfd.h if using many sections
8395 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so

8404 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8406 * app.c: MRI compatibility - allow single quote to start a string.

8408 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8409 * expr.c: Much rewriting, to accomodate MRI syntax for
8410 expressions. Also easier to read now.
8411 * listing.c: Put back defuns
8412 * read.c: modified to accept MRI syntax, put back listing pseudo
8413 ops so that an assembler built with NO_LISTING ignores list ops
8415 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8416 machine is a SPARC or a 29K.
8417 * config/obj-aout.c: added s_sect pseudo op
8418 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8419 fill in the timestamp.
8420 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8421 anymore, define all the relocs which the tc-<x> bit will use so we
8422 can translate from them to the coff types.
8423 * config/tc-a29k.c: reloc_type isn't ane enum any more
8424 * config/tc-m68k.c: Added NO_RELOC definition.
8426 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)

8439 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8441 * symbols.c (local_label_name): symbols now start with ^A.
8443 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8444 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8445 generate these sections. .align: will use NOP_OPCODE or 0
8446 for padding. This is just for being nice to the
8449 * expr.c (operand): changed to generate local label "\001L0"
8450 starting with a ^A so that it is recognized as a local label.
8452 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8454 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8455 i/o opcodes - inb, inw, outb and outw. string manipulation with
8456 att syntax - scmp, slod, smov, ssca, ssto.
8458 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8459 to just after .file .
8461 In obj_crawl_symbol_chain() where it tries to put the external
8462 symbols apart, with the condition:
8463 (!S_IS_DEFINED(symbolP) &&
8464 !S_IS_DEBUG(symbolP) &&
8465 !SF_GET_STATICS(symbolP))
8466 it was moving too many symbols out. So I switch it back to the
8468 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8470 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8471 so that we don't use the F_RELFLG which make the linker complain
8472 that somebody has stripped the relocation info.
8474 Also, the AIX ld program require that the relocation table
8475 is sorted by r_vaddr like the standard ATT assembler does.
8477 [he also changed the sizeof(struct ...)'s into the coff
8478 style FOOSZ macros. I'm not sure this is right, but I can't
8479 remember why. xoxorich.]

8483 * Makefile.in, configure.in, doc: use the doc. Build it, install
8486 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8488 * read.c: white space and comments only.
8490 * configure.in: use the new atof-ns32.c for ns32k.
8492 * write.c: comment change only.
8494 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8495 aren't yet integrated.
8497 * tc-i860.[hc]: blew off the dust. Something must still be done
8498 about conflicting relocation types.
8500 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8503 * tc-i960.c, tc-sparc.c: white space and comments only.
8505 * tc-a29k.h: delete duplicate macro definition.
8507 * new file atof-ns32k.c copied from hack's last unreleased gas.
8509 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8511 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8514 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8515 ChangeLog's prior to this are sketchy at best. I have logs.
8516 They just aren't ChangeLogs.
