1997 * configure.in: Set bfd_gas for all sparc targets in one place,
1998 instead of separately for each. Correctly handle user-supplied
1999 "--enable-bfd-gas" option.
2001 * gdbinit.in: Move "break abort" to end, in case gdb complains.

2011 (indent_level): No longer static.
2012 (print_symbol_value_1): Don't print frag address if it matches

2016 (print_expr_1): Fix whitespace before printing X_add_number.
2018 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
2019 not symbol_new, for symbols holding expression values.
2020 * expr.h (make_expr_symbol): Move declaration here.
2021 * write.c (fix_new_exp): Handle O_add by creating an
2022 expression-valued symbol, and calling fix_new_exp recursively.
2023 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2024 undefined symbol and a constant, fold the constant into the fixup,
2025 and refer to the undefined symbol directly. Then process the
2026 fixup again from scratch.
2027 (write_object_file): Before calling adjust_reloc_syms, make a pass
2028 through the symbol list trying to resolve values.
2030 * write.c (print_fixup): New routine, for debugging.
2031 (write_relocs): Call bfd_install_relocation. Deleted various
2032 hacks for working around problems with bfd_perform_relocation.
2034 * Makefile.in (VERSION): Update to 2.4.90.
2036 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

2049 * write.c (write_relocs): Add file name and line number to
2050 as_fatal calls. Handle bfd_reloc_overflow case specifically when
2051 RELOC_EXPANSION_POSSIBLE.
2053 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2055 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
2056 here. Use them for deciding which PRINTF*LIKE macro definitions

2059 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
2060 default definitions matching what we were doing before.
2061 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2062 always use the varargs form if not using stdarg. It's safe to
2063 always use vfprintf, because libiberty will provide it if the
2064 native system doesn't. Also, always make format be const.
2065 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

2081 deciding whether to record it.
2082 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
2083 false (if defined) as well as checking for reg_section.
2084 (listing_listing): Iterate fetching lines while line number is too
2085 low, and we haven't run off the end of the input file.
2087 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2089 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

2098 * config/ho-*.h: Now-unused files deleted.
2100 * symbols.c (copy_symbol_attributes): New function. Copies BFD
2101 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
2102 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
2103 zero. Don't call obj_frob_forward_symbol.

2106 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
2108 * config/tc-i960.c: Lots of whitespace, comment reformatting,
2110 (strchr): Don't declare.

2112 md_estimate_size_before_relax, md_ri_to_chars,
2113 md_create_short_jump, md_create_long_jump.
2114 (brtab_emit): Use data_section, not SEG_DATA.
2116 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2118 * config/vms-conf.h: new file, manually derived from conf.in.
2119 * config-gas.com: use it, and eliminate obsolete "host.h".

2128 (ppc_es): Clear ppc_current_block.
2129 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
2130 from the csect of the enclosing block.
2132 * config/tc-mips.c (insns_since_cache_access): Remove.
2133 (append_insn): Remove setting of insns_since_cache_access, and
2134 special 4600 handling; it turns out not to be required.
2136 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2138 * config/tc-mips.c (md_shortopts): Remove E.
2139 (md_longopts): Add EB and EL.
2140 (md_parse_option): Handle -EB and -EL as separate options, rather

2150 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
2152 * configure.in: Test for remove, not delete. Fix cross-assembler
2154 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
2157 * read.c (pseudo_set, case O_symbol): If
2158 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
2159 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
2160 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
2162 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
2164 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
2165 many others): new macros; values obtained from "DSTRECRDS.SDL".
2166 * config/obj-vms.h (various): use them.
2167 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
2168 representation (only enum bitfields can avoid being bitstrings).
2169 (bitfield_suffix, setup_basic_type): new routines.
2170 (VMS_typedef_parse): use them. Now recognize bitfields of all
2171 integral types, not just type `int'. Caveat: the representation
2172 used for bitfields still does not work for objects placed in
2173 registers, and gcc's optimizer sometimes puts small structs there.
2175 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2177 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2178 bit from const_flag.
2179 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
2180 (tc_frob_label): define this to call vms_check_for_special_label,
2181 and declare the latter.
2182 * config/obj-vms.c (vax_g_doubles): declare this file-scope
2184 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
2185 (vms_check_for_special_label): new routine (tc_frob_label).
2186 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2187 and `gcc2_compiled.' labels; they won't reach here any more.
2188 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2189 double', use `vax_g_doubles' flag to select type of double.
2190 (VMS_write_object_file) [traceback setup]: don't pass symbols
2191 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
2192 and TBT_Routine_End functions.

2196 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
2197 S_GET_VALUE() to avoid many repeated function calls.
2198 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
2199 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2200 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2201 be obsolete; gcc does it automatically for vms target. It's
2202 also misnamed, because it is for the "VAX C" run-time library,
2203 not the newer "DEC C" one which has much different startup code.]
2204 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2205 `S_GET_xxx(symbol) = new_value'.
2207 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2209 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
2210 not &bfd_abs_section.
2212 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2214 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
2216 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
2218 * expr.c (expr): Don't reduce the difference of two symbols in the
2219 same frag if the symbols are not in normal sections.
2221 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
2222 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
2223 (obj_attach_unwind_info): Do not define. Not needed anymore.
2224 * config/tc-hppa.c: Delete whitespace at EOL.
2225 (struct hppa_fix_struct): Delete fx_unwind field and all references.
2226 (fix_new_hppa): Last arg is now a pointer to an int. Do not
2227 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
2228 fixups, store 32bits of unwind information in the fx_addnumber
2230 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
2231 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
2232 pointer to 32 bits of unwind info.
2233 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
2234 pointer to the dummy symbol; set the addend field to fx_addnumber.
2235 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
2236 rather than &bfd_XXX_section.
2238 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2240 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
2241 value by one; discard adjustments previously being made. From
2244 VMS- and Vax-related changes from Pat Rankin:
2245 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
2246 * vmsconf.sh: no longer have make-gas.com echo text about needing
2247 to modify the gcc-vms driver when intending to use with gcc 1.x.
2248 * as.c (parse_options): suppress 'v' from std_short_options and
2249 eliminate VMS-specific conditional initialization;
2250 [default case]: check for '-v' if md_parse_options doesn't recognize
2252 [default case, #if VMS]: check for filename argument when '-v' seen;
2254 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
2255 for O_big literal operands (double floats and long long ints);
2256 [VMS, md_shortopts]: add second colon after 'v';
2257 (md_parse_options) [VMS, case 'v']: check for argument, so
2258 caller can handle `-v' w/o arg.

2311 * .gdbinit: Deleted.
2312 * aclocal.m4 (GAS_GDBINIT): Deleted.

2316 to ensure that older versions of autoconf aren't used.
2317 * Makefile.in: Added @configure_input@ line.
2318 (configure): Deleted rule.
2320 Tue Sep 13 12:08:20 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2322 * config/obj-coff.c (fixup_segment): After handling the difference
2323 of two symbols from the same segment, set fx_subsy to NULL, to

3383 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
3384 for gcc2's predefined types "long double" (same as double, as

3388 "complex float", "complex double", and "complex long double" are
3391 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
3392 of 0, because the latter indicates success rather than failure

3751 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
3753 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
3755 * vmsconf.sh: In generated file, get ".obj" suffix right, build
3756 source files from other directories into objects in the current
3757 directory, and specify PSECT attributes explicitly to linker.
3758 Also added missing label.
3759 * Makefile.in (stamp-mk.com): Reference new variable

3777 argument, the reloc type.
3778 (load_register): Pass reloc type to macro_build for 'u'.
3779 (macro): Likewise. For M_LA_AB permit a difference expression
3780 when generating embedded PIC code between an arbitrary symbol and
3781 a symbol in the .text section.
3782 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and

3823 (hppa_tc_symbol): Likewise.
3825 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
3826 elf_tc_make_sections stuff. It was there to support PA braindamage
3827 which has been fixed, and in the case of elf_tc_make_sections is
3828 redundant with elf_tc_final_processing.
3830 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3848 don't spew remainder of input file in error message.
3849 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
3850 message with reloc type and try to process remainder of file.

3862 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
3863 flag rather than signedp field. Only permit extended range if
3864 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
3865 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
3867 * config/tc-ppc.c (ppc_size): New static variable.
3868 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
3869 (md_begin): If an instruction has a size specific flag set, only
3870 add it if we are assembling that size.

3874 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
3875 cross section PC relative relocs right for COFF and ELF.
3877 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3879 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

3884 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
3885 the type of symbol set symbols which happen to be in the absolute
3886 or undefined section.

3890 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
3891 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
3892 and -many (all architectures).

3902 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3903 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3905 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3906 branch with an instruction that uses $at, in case the branch is
3908 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3909 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3910 to make it pcrel_offset.
3911 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3912 reloc->address; another gruesome hack to get gas reloc handling to
3915 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3917 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3920 (emit_insn): New function.
3921 (md_assemble): Call it.
3922 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3924 (lituse_pending): New variable. Set by anything that generates a
3925 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3926 tested by code that might want to emit a LITUSE reloc.
3927 (emit_unaligned_io): New function. Currently calls md_assemble,
3928 but it should eventually be converted to generate the insn itself
3929 and call emit_insn directly.
3930 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3931 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3932 emit_bis_r): Likewise.
3933 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3934 (alpha_ip, label get_macro): Don't emit the final instruction if
3936 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3937 unaligned memory access macros.
3938 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3939 the value can't be resolved.
3941 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3943 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3944 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3945 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

3957 * config/tc-mips.c (enum mips_pic_level): New enum.
3958 (mips_pic): Change from int to enum mips_pic_level. Change all
3959 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3960 (load_address): Handle EMBEDDED_PIC.
3961 (macro): Handle EMBEDDED_PIC in all PIC cases.
3962 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3963 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3964 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3965 works). Do not permit -G with SVR4_PIC.
3966 (s_abicalls): Warn if -G was used, and force -G 0.
3967 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3968 anything but a.out, not just for ELF. For ECOFF, don't generate a
3969 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3971 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3973 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3975 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3976 parameters to avoid losing when compiling with HP CC.
3977 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3979 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3981 * Makefile.in (config-stamp): If `defs' is defined, emit a
3982 preprocessor directive to create a macro named by this value into
3983 config.new; don't explicitly go for BFD_ASSEMBLER.
3984 * configure.in: Define `defs', not `BFDDEF'. Set it to
3985 MANY_SEGMENTS for any obj-coffbfd target.
3986 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3987 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3989 (LOCAL_LOADLIBES): Deleted.
3990 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3991 * config/m88kcoff.mt (TDEFINES): Ditto.
3992 * config/ebmon29k.mt: Deleted.

4017 bfd_set_symtab is called.
4018 (dump_section_relocs): Note whether a symbol is a section symbol
4020 (adjust_reloc_syms): For now, always supply an absolute symbol for
4021 fixups without symbols but not yet `done'. Use section_symbol to
4022 get the symbol, instead of going directly for abs_symbol.
4023 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4024 reloc is not a section symbol and is not in the symbol table.
4025 (set_symtab): New function, broken out from write_object_file.
4026 Counts symbol table instead of relying on an earlier count.
4027 (write_object_file): Call set_symtab, but do it after potentially
4028 invoking the *_frob_file macros. Don't bother counting symbols.
4029 Call symbol_remove, instead of expanding it in place. Moved the
4030 conditionalized `object_file_size' declaration down to
4031 conditionalized block where it's used. When using the absolute
4032 symbol for a fixup without a symbol, set sy_used_in_reloc.
4033 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4034 the correct symbol for the absolute section.
4036 * subsegs.c (section_symbol): Use symbol_new instead of
4037 symbol_make, since we may want it to go into the symbol table.
4038 Make the new symbol have internal linkage. If
4039 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4040 symbol with the newly created GAS symbol.
4041 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
4042 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

4049 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
4050 (sparc_ip, label "immediate"): Reject constants for pcrel
4051 instructions only if the relocation type indicates a "call"
4052 instruction and the offset is within range of a "jmpl %g0". If
4053 it's not in range, use the absolute section symbol plus an offset.
4054 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
4056 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
4058 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
4061 * configure.in: Eliminated all targets using obj-coff but not
4062 defining BFD_ASSEMBLER; I think all such targets that are
4063 supported will be matched by real CPU-OS combinations earlier in
4065 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
4066 some comments about the dpx2 configuration, but left it disabled,
4067 since it couldn't be reached before.
4068 (target a29k-amd-ebmonold): Deleted.
4070 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4078 the 'j' operand if there are no further alternatives for this
4081 * config/obj-coffbfd.c (adjust_stab_section): Initialize
4082 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
4083 is not SEG_UNKNOWN rather than checking whether it is >= 0.
4085 * config/tc-mips.c (mips_align): Take new argument, label, and use
4086 it instead of global insn_label.
4087 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
4088 call to mips_emit_delay and pass it to mips_align.
4090 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4092 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
4094 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
4095 argument to a .callinfo directive. Don't loop forever on errors.
4097 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
4098 use pre-defined registers as arguments.

4103 S_IS_EXTERNAL when deciding whether to discard a symbol.
4105 * config-gas.com: Scan Makefile.in, not version.c, for current

4110 values to reduce number of lookups with S_GET_VALUE. Skip debug
4111 symbols to avoid "a really nasty bug". (From Holger Teutsch,
4112 holger@botbso.rhein-main.de.)
4113 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
4114 field. (Also from Holger Teutsch.) Watch for a would-be register
4115 mask that spans frags.
4117 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
4118 this_base, not line_base. (Patch from Andreas Arens,

4121 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
4122 look local if they're exported or undefined. Used to be done for
4125 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
4126 Get it from the looked-up symbol, instead of using the string from
4127 the input stream, which is no longer null-terminated.
4128 (LEX_PCT): New macro, defaults to 0.
4129 (lex_type): Use it for `%'.
4131 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

4181 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
4182 0xffff for 'j' to be compatible with MIPS assembler. These
4183 numbers are actually treated as negative.

4196 silently compiling to do nothing.
4197 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
4199 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

5766 Delete dead code. Simplify.
5767 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
5768 applied are in range. Use bfd_put_32 rather than inserting each

5847 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
5848 standard hpux include files to pick up various function decls.
5850 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

5883 of interest to the linker. ENTRY/EXIT relocations for SOM are
5884 an example of marker relocations.
5885 * write.c (write_relocs): Instead of assuming size of a relocation
5886 is 4 bytes, pick up the size from relocation itself.

5916 pass new argument for i, j and o cases.
5917 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

6138 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
6139 the table, require that the one without bit 0x1000000 set come
6140 first. Require further that it be case 'b' or 'P'. The a29k
6141 opcode table already meets these constraints.
6142 (machine_ip): When handling case 'i' or 'A', make sure that the

6198 * write.c (write_relocs): For relocs that are pc_relative and
6199 pcrel_offset and not partial_inplace, adjust reloc->addend to

6252 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
6254 * configure.in: Set bfd_gas for all sparc targets. Added facility
6255 for keeping or rejecting configurations still under development;
6256 default is to assume production environment, and reject configs
6257 still being worked on. Mark Elf configurations (except sparc and
6258 i386) as developmental. Deleted cases matching some generic names
6259 in favor of more specific names. (E.g., when we get Alpha

6277 for functions only used within tc-hppa.c, likewise for structures,
6278 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
6279 conditional code in a few small places.
6281 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
6282 structures, global variables, forward declarations together.

6284 conditional code -- try to group conditional code together
6285 into a few places. Make all functions and variables which
6286 are only used within tc-hppa.c static. PARAMize all functions.
6287 Add comments to functions. Delete unused functions, variables,
6288 #defines, etc. Delete unused members within structures. Delete
6289 ldil;ble hacks -- it is believed they were installed to work
6290 around old gas bugs. Avoid using mixed case for local
6291 functions, variables, and structures. Fix formatting problems
6292 not found by GNU-indent. Add FIXME notices for things which
6293 should be worked on the near future. Delete lots of old
6294 useless (1.36 PA-SOM) code.

6323 a multiple of the section alignment rather than always a
6326 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
6327 bits are zero (eg they specify no relocations), then do not even
6328 bother adding their entries to thesymextn section.

6373 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
6375 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
6376 ELF, since the ELF object format does not have these type of
6377 relocations. Change the abort into as as_bad and return
6378 BFD_RELOC_NONE to silence compiler warnings.
6379 (md_assemble): Keep track of the instruction size. Allow white
6380 space between the $ and the constant for compatibility with older
6381 gases and other assemblers.

7456 * Extensive changes to permit symbols to contain any expression
7457 type and to delay the computation of the expression until the
7458 value is actually needed. This permits setting symbols to values
7459 calculated based on object code size. Expressions were changed to
7460 no longer be in a section, to stop the overloading of segment and
7461 expression type that previously occurred.
7463 * as.c (big_section, pass1_section, diff_section, absent_section):
7465 (expr_section): Added (used for dummy symbols which hold

7549 (previous_section, previous_subsection): New vars.
7550 (obj_elf_section): Save current place in case DWARF code wants us
7551 to pop back to it. Handle unquoted section name as well as quoted
7552 section name. Don't crash on invalid strings.
7553 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

7665 sy_resolved and sy_resolving single bit fields.
7666 * symbols.c (symbol_new): Don't initialize sy_forward field.

8865 dropping a space immediately following an identifier.
8866 * expr.c, write.c: Rewrote assert expressions to not use multiple
8867 lines; I don't think that can be done portably.
8868 * config/tc-mips.c (macro): Use $AT if target register is zero in
8869 load instruction, which it can be for a floating point load.

8943 prototypes for all static functions. Moved existing minimal
8944 debugging format support info #ifndef OBJ_ECOFF blocks.

8993 * make-gas.com: Find obstack.obj if it's not in the current
8995 * read.c (s_ignore): Don't declare is_end_of_line. It's
8996 redundant, and triggers a VMS gcc compiler bug.
8998 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8999 current segment as an argument. (Ignored in all cases but VMS.)
9000 All callers and definitions changed.

9024 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9027 * configure.in: mips-bsd configuration was missing format spec.
9030 * Makefile.in (Makefile): Depends on configure.in.
9032 * config/tc-mips.c (append_insn): Don't check for alignment of
9033 frag in memory; alignment of instructions in section is a separate

9054 constants are accepted, but symbolic values are not. GCC will not
9055 generate the latter currently.
9057 * frags.c (frag_init): New function.
9058 (zero_address_frag, bss_address_frag): Now initialized at run
9060 * as.c (main): Call frag_init.

9350 * config-gas.com: New file. Script for VMS systems to set up the
9351 configuration to build gas for VMS, and create config.status.
9352 * make-gas.com: Redone to work with new scheme.
9353 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
9355 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
9356 will swap bytes if needed on a big endian system. Use throughout
9358 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9359 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9360 types of malformed stabs. Change parsing algorithm so that we are
9361 more certain of having all of the information that we need on hand.
9362 * obj-vms.c (final_forward_reference): New function, used to help
9363 resolve the data types of as many struct elements as possible
9364 when some part of the struct is not fully defined by the compiler.
9365 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
9367 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9368 as symbols as well in the object file. Look for external functions
9369 that start with "__vt.", and turn them into variables, since the
9370 g++ compiler is incapable of doing this.
9371 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9373 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9374 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9375 have the name of the source file yet.

9381 SEG_DATA or SEG_E1 if needed.
9382 (s_lcomm): Likewise with bss_section.
9383 (s_fill): Use memset, not bzero.
9385 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9407 (big_section, reg_section, pass1_section, diff_section,
9408 absent_section, text_section, data_section, bss_section): If
9409 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
9410 mapping to segT enum values.
9411 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
9412 if these are used or defined, if BFD_ASSEMBLER.
9413 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
9414 subseg_new split into two functions.
9415 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
9417 * as.h (volatile): Don't define if already defined.
9418 (had_errors, had_warnings): Provide prototypes for ANSI C even if
9420 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
9421 declare with format attribute for -Wformat checking.
9423 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
9425 * app.c, config/tc-*.c: Don't include read.h, since it is already
9428 * These are based on patches from Minh Tran-le
9429 <mtranle@paris.intellicorp.com>.
9430 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
9431 obj_format coffbfd and gas_target i386coff for target.
9432 (i[34]86-*-isc*): New host (uses sysv).
9433 * config/i386aix.mt: Removed (no longer used).
9434 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9436 (LDFLAGS): Added, defined as -shlib.
9437 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9438 * config/te-sco386.h (LOCAL_LABEL): Don't define.
9439 (DOT_LABEL_PREFIX): Define.
9440 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
9441 name rather than L0\001.
9442 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
9444 * symbols.c, symbols.h (local_bss_counter): Removed.

9453 (size_section): Restored sanity check.
9454 (do_relocs_for): Base section address on s_paddr rather than
9455 computing it. Adjust a29k R_IHIHALF special case to account for
9456 section paddr (used to require paddr to be zero). If there are no
9457 reclos, set s_relptr to 0. Set relocation size in object_headers.
9458 (fill_section): Always set s_vaddr here, removing
9459 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9460 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9461 Set STYP_INFO for .comment.

9465 H_{SET,GET}_* macros.
9466 (do_linenos_for): Set lineno size in object_headers.
9467 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9468 set s_vaddr here. If string_byte_count remains 4, set it back to
9469 0, and only write strings out if there are some. Call
9470 fill_section before do_relocs_for and do_linenos_for.
9471 (obj_coff_section): Handle optional quoted second argument giving
9472 section characteristics.
9473 (obj_coff_bss): Added to handle .bss.
9474 (obj_coff_ident): Added to handle .ident (puts string in .comment

9494 (do_scrub_next_char): For \", return " not '.
9495 (symbol_chars): Now const.
9497 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9498 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9500 * config/obj-coff.h: Don't use #elif.
9502 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9503 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

9532 never set segment address for SEG_E2 (.bss) and don't write out
9533 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
9534 (obj_coff_endef): Don't merge labels or symbols awaiting forward
9535 definitions, and don't merge tags with non-tags. Check for .bf
9536 rather than just checking whether the second character is b and
9537 the third character is f.
9538 (obj_coff_val): gcc can generate values which we don't handle
9539 correctly; discard information for now, since it only affects the
9540 debugging information.

9542 (yank_symbols): Don't merge labels.
9543 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

9840 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9841 sections starting from zero, rather than making them consecutive.
9842 This makes subsequent reloc calculations easier, esp if the object
9843 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9844 allocate lcomm in .data rather than in .bss. It seems that some
9845 tools can't cope with a non-zero sized bss before linkage.
9847 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9849 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

9871 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
9873 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
9874 .word is < -32768 or > 32767. The -J flag causes the error to be
9875 ignored. This is to catch over-sized switches generated by gcc on
9876 systems which don't support the broken .word hack.
9877 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
9878 write.c (fixup_segment): check for signed .word overflow if
9879 WARN_SIGNED_OVERFLOW_WORD.

9908 From Steve Chamberlain:
9909 Makefile.in: Handle m68*-*-coff*.

9922 (fixup_segment) set fx_subsy to 0.
9923 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
9925 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
9928 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

9955 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9957 * config/tc-m68k.c (init_table): Now const. Always include 68851
9958 data, so that "bc" is available to 68040 cache instructions.
9959 Added "tt0", "tt1", and 68ec030 variants.
9960 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9961 (enum _register): Added TT0, TT1.
9962 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9963 line number correctly in "internal error" messages. Don't print
9964 architecture-mismatch message for operand errors.
9966 From Colin Smith (colin@wrs.com):
9967 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

9989 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9990 has already been formatted (but may still contain %-characters).
9993 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9995 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9996 written with indirection on the last two operands, which can be
9997 either data or address registers. Added a new operand type 'r'
9998 which accepts either register type. Added '(' to notend stuff in
9999 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

10310 * Makefile.in: added tooldir and program_prefix.
10312 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
10314 * write.{c,h} (fix_new): Make these declarations consistent.
10316 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
10318 * Makefile.in (strerror.o): Add rule so that broken Sun make can
10321 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10323 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10325 * expr.c (operand): if can't work out what sort of operand it is,
10326 then look through FLT_CHARS for a hint.
10328 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10330 * Makefile.in, configure.in: removed traces of namesubdir,
10331 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10332 copyrights to '92, changed some from Cygnus to FSF.
10334 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10335 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10336 copyrights to '92, changed some from Cygnus to FSF.
10338 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10340 * expr.c: If an expression is single comma, then return with
10341 SEG_ABSENT rather than an error - since the sparc front end does
10342 really strange things with things like fbge,a
10344 * as.h: include bfd.h if using many sections
10345 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10346 local labels didn't work.
10347 * listing.c (list_symbol_table): don't core dump when there's no
10349 * write.c, write.h: call fix_new with the right number of args on
10351 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10354 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10356 * app.c: MRI compatibility - allow single quote to start a string.
10357 * as.c: fix typo recently introduced.
10358 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10359 * expr.c: Much rewriting, to accomodate MRI syntax for
10360 expressions. Also easier to read now.
10361 * listing.c: Put back defuns
10362 * read.c: modified to accept MRI syntax, put back listing pseudo
10363 ops so that an assembler built with NO_LISTING ignores list ops
10365 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10366 machine is a SPARC or a 29K.
10367 * config/obj-aout.c: added s_sect pseudo op
10368 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10369 fill in the timestamp.
10370 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10371 anymore, define all the relocs which the tc-<x> bit will use so we
10372 can translate from them to the coff types.
10373 * config/tc-a29k.c: reloc_type isn't ane enum any more
10374 * config/tc-m68k.c: Added NO_RELOC definition.
10376 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10378 * Makefile.in: put header files before C source for TAGS; remove
10379 references to non-existent syscalls.h.
10381 * read.c, write.c subsegs.c: back out the .bss changes.
10383 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10385 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10387 * a.out.h: removed.
10389 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10391 * symbols.c (local_label_name): symbols now start with ^A.
10393 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10394 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10395 generate these sections. .align: will use NOP_OPCODE or 0
10396 for padding. This is just for being nice to the
10399 * expr.c (operand): changed to generate local label "\001L0"
10400 starting with a ^A so that it is recognized as a local label.
10402 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10404 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10405 i/o opcodes - inb, inw, outb and outw. string manipulation with
10406 att syntax - scmp, slod, smov, ssca, ssto.
10408 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10409 to just after .file .
10411 In obj_crawl_symbol_chain() where it tries to put the external
10412 symbols apart, with the condition:
10413 (!S_IS_DEFINED(symbolP) &&
10414 !S_IS_DEBUG(symbolP) &&
10415 !SF_GET_STATICS(symbolP))
10416 it was moving too many symbols out. So I switch it back to the
10418 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10420 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10421 so that we don't use the F_RELFLG which make the linker complain
10422 that somebody has stripped the relocation info.
10424 Also, the AIX ld program require that the relocation table
10425 is sorted by r_vaddr like the standard ATT assembler does.
10427 [he also changed the sizeof(struct ...)'s into the coff
10428 style FOOSZ macros. I'm not sure this is right, but I can't
10429 remember why. xoxorich.]
10431 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
10433 * Makefile.in, configure.in, doc: use the doc. Build it, install
10436 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10438 * read.c: white space and comments only.
10440 * configure.in: use the new atof-ns32.c for ns32k.
10442 * write.c: comment change only.
10444 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10445 aren't yet integrated.
10447 * tc-i860.[hc]: blew off the dust. Something must still be done
10448 about conflicting relocation types.
10450 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10453 * tc-i960.c, tc-sparc.c: white space and comments only.
10455 * tc-a29k.h: delete duplicate macro definition.
10457 * new file atof-ns32k.c copied from hack's last unreleased gas.
10459 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10461 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10464 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10465 ChangeLog's prior to this are sketchy at best. I have logs.
10466 They just aren't ChangeLogs.
