2003 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2005 * configure.in: Set bfd_gas for all sparc targets in one place,
2006 instead of separately for each. Correctly handle user-supplied
2007 "--enable-bfd-gas" option.
2009 * gdbinit.in: Move "break abort" to end, in case gdb complains.

2019 (indent_level): No longer static.
2020 (print_symbol_value_1): Don't print frag address if it matches

2024 (print_expr_1): Fix whitespace before printing X_add_number.
2026 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
2027 not symbol_new, for symbols holding expression values.
2028 * expr.h (make_expr_symbol): Move declaration here.
2029 * write.c (fix_new_exp): Handle O_add by creating an
2030 expression-valued symbol, and calling fix_new_exp recursively.
2031 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2032 undefined symbol and a constant, fold the constant into the fixup,
2033 and refer to the undefined symbol directly. Then process the
2034 fixup again from scratch.
2035 (write_object_file): Before calling adjust_reloc_syms, make a pass
2036 through the symbol list trying to resolve values.
2038 * write.c (print_fixup): New routine, for debugging.
2039 (write_relocs): Call bfd_install_relocation. Deleted various
2040 hacks for working around problems with bfd_perform_relocation.
2042 * Makefile.in (VERSION): Update to 2.4.90.
2044 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

2057 * write.c (write_relocs): Add file name and line number to
2058 as_fatal calls. Handle bfd_reloc_overflow case specifically when
2059 RELOC_EXPANSION_POSSIBLE.
2061 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2063 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
2064 here. Use them for deciding which PRINTF*LIKE macro definitions

2067 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
2068 default definitions matching what we were doing before.
2069 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2070 always use the varargs form if not using stdarg. It's safe to
2071 always use vfprintf, because libiberty will provide it if the
2072 native system doesn't. Also, always make format be const.
2073 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

2089 deciding whether to record it.
2090 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
2091 false (if defined) as well as checking for reg_section.
2092 (listing_listing): Iterate fetching lines while line number is too
2093 low, and we haven't run off the end of the input file.
2095 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2097 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
2099 * ecoff.c (ecoff_generate_asm_lineno): check if

2106 * config/ho-*.h: Now-unused files deleted.
2108 * symbols.c (copy_symbol_attributes): New function. Copies BFD
2109 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
2110 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
2111 zero. Don't call obj_frob_forward_symbol.

2120 md_estimate_size_before_relax, md_ri_to_chars,
2121 md_create_short_jump, md_create_long_jump.
2122 (brtab_emit): Use data_section, not SEG_DATA.
2124 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2126 * config/vms-conf.h: new file, manually derived from conf.in.

2137 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
2138 from the csect of the enclosing block.
2140 * config/tc-mips.c (insns_since_cache_access): Remove.
2141 (append_insn): Remove setting of insns_since_cache_access, and
2142 special 4600 handling; it turns out not to be required.
2144 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2146 * config/tc-mips.c (md_shortopts): Remove E.
2147 (md_longopts): Add EB and EL.
2148 (md_parse_option): Handle -EB and -EL as separate options, rather

2158 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
2160 * configure.in: Test for remove, not delete. Fix cross-assembler
2162 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to

2166 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
2167 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
2168 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
2170 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
2172 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
2173 many others): new macros; values obtained from "DSTRECRDS.SDL".
2174 * config/obj-vms.h (various): use them.
2175 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
2176 representation (only enum bitfields can avoid being bitstrings).
2177 (bitfield_suffix, setup_basic_type): new routines.
2178 (VMS_typedef_parse): use them. Now recognize bitfields of all
2179 integral types, not just type `int'. Caveat: the representation
2180 used for bitfields still does not work for objects placed in
2181 registers, and gcc's optimizer sometimes puts small structs there.
2183 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2185 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2186 bit from const_flag.
2187 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

2192 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
2193 (vms_check_for_special_label): new routine (tc_frob_label).
2194 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2195 and `gcc2_compiled.' labels; they won't reach here any more.
2196 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2197 double', use `vax_g_doubles' flag to select type of double.
2198 (VMS_write_object_file) [traceback setup]: don't pass symbols
2199 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
2200 and TBT_Routine_End functions.

2204 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
2205 S_GET_VALUE() to avoid many repeated function calls.
2206 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
2207 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2208 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2209 be obsolete; gcc does it automatically for vms target. It's
2210 also misnamed, because it is for the "VAX C" run-time library,
2211 not the newer "DEC C" one which has much different startup code.]
2212 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2213 `S_GET_xxx(symbol) = new_value'.
2215 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2217 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
2218 not &bfd_abs_section.
2220 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2222 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
2224 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
2226 * expr.c (expr): Don't reduce the difference of two symbols in the
2227 same frag if the symbols are not in normal sections.
2229 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
2230 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
2231 (obj_attach_unwind_info): Do not define. Not needed anymore.
2232 * config/tc-hppa.c: Delete whitespace at EOL.
2233 (struct hppa_fix_struct): Delete fx_unwind field and all references.
2234 (fix_new_hppa): Last arg is now a pointer to an int. Do not
2235 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
2236 fixups, store 32bits of unwind information in the fx_addnumber
2238 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
2239 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
2240 pointer to 32 bits of unwind info.
2241 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
2242 pointer to the dummy symbol; set the addend field to fx_addnumber.
2243 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
2244 rather than &bfd_XXX_section.
2246 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2248 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
2249 value by one; discard adjustments previously being made. From
2252 VMS- and Vax-related changes from Pat Rankin:
2253 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
2254 * vmsconf.sh: no longer have make-gas.com echo text about needing
2255 to modify the gcc-vms driver when intending to use with gcc 1.x.
2256 * as.c (parse_options): suppress 'v' from std_short_options and
2257 eliminate VMS-specific conditional initialization;
2258 [default case]: check for '-v' if md_parse_options doesn't recognize

2262 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
2263 for O_big literal operands (double floats and long long ints);
2264 [VMS, md_shortopts]: add second colon after 'v';
2265 (md_parse_options) [VMS, case 'v']: check for argument, so
2266 caller can handle `-v' w/o arg.

2270 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET
2271 is defined, put the tx_offset into the r_offset.

2311 Rewrite handling of program_transform_name.
2313 * configure.in: Test for functions unlink and delete.

2319 * .gdbinit: Deleted.
2320 * aclocal.m4 (GAS_GDBINIT): Deleted.

2324 to ensure that older versions of autoconf aren't used.
2325 * Makefile.in: Added @configure_input@ line.
2326 (configure): Deleted rule.
2328 Tue Sep 13 12:08:20 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2330 * config/obj-coff.c (fixup_segment): After handling the difference
2331 of two symbols from the same segment, set fx_subsy to NULL, to

3759 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
3761 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
3763 * vmsconf.sh: In generated file, get ".obj" suffix right, build
3764 source files from other directories into objects in the current
3765 directory, and specify PSECT attributes explicitly to linker.
3766 Also added missing label.

3785 argument, the reloc type.
3786 (load_register): Pass reloc type to macro_build for 'u'.
3787 (macro): Likewise. For M_LA_AB permit a difference expression
3788 when generating embedded PIC code between an arbitrary symbol and
3789 a symbol in the .text section.
3790 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
3791 BFD_RELOC_PCREL_LO16 to be emitted.

3799 * subsegs.c (subsegs_begin): Call memset with args in the correct
3801 (subseg_get): Clear newly allocated seginfo, set its pointer slots
3802 to NULL instead of 0.

3806 * config/tc-hppa.c (pa_procend): Handle case where label was
3807 defined after the .proc directive.
3809 * config/tc-hppa.c (pa_procend): Give an error if we encounter a

3831 (hppa_tc_symbol): Likewise.
3833 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
3834 elf_tc_make_sections stuff. It was there to support PA braindamage
3835 which has been fixed, and in the case of elf_tc_make_sections is
3836 redundant with elf_tc_final_processing.
3838 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3840 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

3856 don't spew remainder of input file in error message.
3857 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
3858 message with reloc type and try to process remainder of file.
3860 * doc/Makefile.in (install-info-as, install-info-gasp): New
3861 targets, now explicitly checking $(srcdir) for info files.
3862 (install-info): Depend on both of them; do nothing more.

3866 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
3868 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3870 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
3871 flag rather than signedp field. Only permit extended range if
3872 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
3873 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
3875 * config/tc-ppc.c (ppc_size): New static variable.
3876 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
3877 (md_begin): If an instruction has a size specific flag set, only
3878 add it if we are assembling that size.
3880 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3882 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
3883 cross section PC relative relocs right for COFF and ELF.
3885 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3887 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
3888 (OBJ_PROCESS_STAB): Don't define.

3892 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
3893 the type of symbol set symbols which happen to be in the absolute
3894 or undefined section.

3898 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
3899 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
3900 and -many (all architectures).
3902 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3904 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
3905 involving a function symbol which is not a plabel to zero.

3910 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3911 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3913 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3914 branch with an instruction that uses $at, in case the branch is
3916 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3917 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3918 to make it pcrel_offset.
3919 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3920 reloc->address; another gruesome hack to get gas reloc handling to
3923 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3925 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3928 (emit_insn): New function.
3929 (md_assemble): Call it.
3930 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3932 (lituse_pending): New variable. Set by anything that generates a
3933 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3934 tested by code that might want to emit a LITUSE reloc.
3935 (emit_unaligned_io): New function. Currently calls md_assemble,
3936 but it should eventually be converted to generate the insn itself
3937 and call emit_insn directly.
3938 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3939 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3940 emit_bis_r): Likewise.
3941 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3942 (alpha_ip, label get_macro): Don't emit the final instruction if
3944 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3945 unaligned memory access macros.
3946 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3947 the value can't be resolved.
3949 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3951 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3952 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3953 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3955 (mips_force_relocation): New function.
3956 (md_apply_fix): Set fixP->fx_done appropriately.
3957 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

3965 * config/tc-mips.c (enum mips_pic_level): New enum.
3966 (mips_pic): Change from int to enum mips_pic_level. Change all
3967 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3968 (load_address): Handle EMBEDDED_PIC.
3969 (macro): Handle EMBEDDED_PIC in all PIC cases.
3970 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3971 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3972 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3973 works). Do not permit -G with SVR4_PIC.
3974 (s_abicalls): Warn if -G was used, and force -G 0.
3975 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3976 anything but a.out, not just for ELF. For ECOFF, don't generate a
3977 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3979 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3981 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3983 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3984 parameters to avoid losing when compiling with HP CC.
3985 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3987 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3989 * Makefile.in (config-stamp): If `defs' is defined, emit a
3990 preprocessor directive to create a macro named by this value into
3991 config.new; don't explicitly go for BFD_ASSEMBLER.
3992 * configure.in: Define `defs', not `BFDDEF'. Set it to
3993 MANY_SEGMENTS for any obj-coffbfd target.
3994 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3995 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3997 (LOCAL_LOADLIBES): Deleted.
3998 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3999 * config/m88kcoff.mt (TDEFINES): Ditto.
4000 * config/ebmon29k.mt: Deleted.
4001 * config/h8300hds.mt: Deleted.
4002 * config/ic960coff.mt: Deleted.
4003 * config/sparc.mt: Deleted.
4004 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

4006 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
4007 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

4025 bfd_set_symtab is called.
4026 (dump_section_relocs): Note whether a symbol is a section symbol
4028 (adjust_reloc_syms): For now, always supply an absolute symbol for
4029 fixups without symbols but not yet `done'. Use section_symbol to
4030 get the symbol, instead of going directly for abs_symbol.
4031 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4032 reloc is not a section symbol and is not in the symbol table.
4033 (set_symtab): New function, broken out from write_object_file.
4034 Counts symbol table instead of relying on an earlier count.
4035 (write_object_file): Call set_symtab, but do it after potentially
4036 invoking the *_frob_file macros. Don't bother counting symbols.
4037 Call symbol_remove, instead of expanding it in place. Moved the
4038 conditionalized `object_file_size' declaration down to
4039 conditionalized block where it's used. When using the absolute
4040 symbol for a fixup without a symbol, set sy_used_in_reloc.
4041 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4042 the correct symbol for the absolute section.
4044 * subsegs.c (section_symbol): Use symbol_new instead of
4045 symbol_make, since we may want it to go into the symbol table.
4046 Make the new symbol have internal linkage. If
4047 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4048 symbol with the newly created GAS symbol.
4049 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
4050 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

4055 (in_signed_range): New function.
4057 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
4058 (sparc_ip, label "immediate"): Reject constants for pcrel
4059 instructions only if the relocation type indicates a "call"
4060 instruction and the offset is within range of a "jmpl %g0". If
4061 it's not in range, use the absolute section symbol plus an offset.
4062 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
4064 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
4066 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
4069 * configure.in: Eliminated all targets using obj-coff but not
4070 defining BFD_ASSEMBLER; I think all such targets that are
4071 supported will be matched by real CPU-OS combinations earlier in
4073 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
4074 some comments about the dpx2 configuration, but left it disabled,
4075 since it couldn't be reached before.
4076 (target a29k-amd-ebmonold): Deleted.
4078 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4086 the 'j' operand if there are no further alternatives for this
4089 * config/obj-coffbfd.c (adjust_stab_section): Initialize
4090 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
4091 is not SEG_UNKNOWN rather than checking whether it is >= 0.
4093 * config/tc-mips.c (mips_align): Take new argument, label, and use
4094 it instead of global insn_label.
4095 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
4096 call to mips_emit_delay and pass it to mips_align.
4098 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4100 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
4102 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
4103 argument to a .callinfo directive. Don't loop forever on errors.
4105 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
4106 use pre-defined registers as arguments.

4111 S_IS_EXTERNAL when deciding whether to discard a symbol.
4113 * config-gas.com: Scan Makefile.in, not version.c, for current
4114 version number. Delete all versions of temp files when finished
4115 with them. Create config.h.
4117 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
4118 values to reduce number of lookups with S_GET_VALUE. Skip debug
4119 symbols to avoid "a really nasty bug". (From Holger Teutsch,
4120 holger@botbso.rhein-main.de.)
4121 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
4122 field. (Also from Holger Teutsch.) Watch for a would-be register
4123 mask that spans frags.
4125 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
4126 this_base, not line_base. (Patch from Andreas Arens,
4127 ari@obelix.av.rwth-aachen.de.)
4129 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
4130 look local if they're exported or undefined. Used to be done for
4133 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
4134 Get it from the looked-up symbol, instead of using the string from
4135 the input stream, which is no longer null-terminated.
4136 (LEX_PCT): New macro, defaults to 0.
4137 (lex_type): Use it for `%'.
4139 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
4140 (vip_op): Now static, and returns void. Callers changed. Added
4142 (vip): Ditto. Call as_fatal directly if a program bug is

4189 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
4190 0xffff for 'j' to be compatible with MIPS assembler. These
4191 numbers are actually treated as negative.

4201 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
4202 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this
4203 work. It still doesn't. It now fails to compile, instead of
4204 silently compiling to do nothing.
4205 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
4207 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits
4210 Handle Alpha load-immediate-FP pseudo-instructions:

5774 Delete dead code. Simplify.
5775 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
5776 applied are in range. Use bfd_put_32 rather than inserting each

5892 an example of marker relocations.
5893 * write.c (write_relocs): Instead of assuming size of a relocation
5894 is 4 bytes, pick up the size from relocation itself.

6146 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
6147 the table, require that the one without bit 0x1000000 set come
6148 first. Require further that it be case 'b' or 'P'. The a29k
6149 opcode table already meets these constraints.
6150 (machine_ip): When handling case 'i' or 'A', make sure that the

6206 * write.c (write_relocs): For relocs that are pc_relative and
6207 pcrel_offset and not partial_inplace, adjust reloc->addend to

6260 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
6262 * configure.in: Set bfd_gas for all sparc targets. Added facility
6263 for keeping or rejecting configurations still under development;
6264 default is to assume production environment, and reject configs
6265 still being worked on. Mark Elf configurations (except sparc and
6266 i386) as developmental. Deleted cases matching some generic names
6267 in favor of more specific names. (E.g., when we get Alpha

6285 for functions only used within tc-hppa.c, likewise for structures,
6286 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
6287 conditional code in a few small places.
6289 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
6290 structures, global variables, forward declarations together.

6292 conditional code -- try to group conditional code together
6293 into a few places. Make all functions and variables which
6294 are only used within tc-hppa.c static. PARAMize all functions.
6295 Add comments to functions. Delete unused functions, variables,
6296 #defines, etc. Delete unused members within structures. Delete
6297 ldil;ble hacks -- it is believed they were installed to work
6298 around old gas bugs. Avoid using mixed case for local
6299 functions, variables, and structures. Fix formatting problems
6300 not found by GNU-indent. Add FIXME notices for things which
6301 should be worked on the near future. Delete lots of old
6302 useless (1.36 PA-SOM) code.

6331 a multiple of the section alignment rather than always a
6334 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
6335 bits are zero (eg they specify no relocations), then do not even
6336 bother adding their entries to thesymextn section.

6381 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
6383 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
6384 ELF, since the ELF object format does not have these type of
6385 relocations. Change the abort into as as_bad and return
6386 BFD_RELOC_NONE to silence compiler warnings.
6387 (md_assemble): Keep track of the instruction size. Allow white
6388 space between the $ and the constant for compatibility with older
6389 gases and other assemblers.

7462 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
7464 * Extensive changes to permit symbols to contain any expression
7465 type and to delay the computation of the expression until the
7466 value is actually needed. This permits setting symbols to values
7467 calculated based on object code size. Expressions were changed to
7468 no longer be in a section, to stop the overloading of segment and
7469 expression type that previously occurred.
7471 * as.c (big_section, pass1_section, diff_section, absent_section):
7473 (expr_section): Added (used for dummy symbols which hold

7557 (previous_section, previous_subsection): New vars.
7558 (obj_elf_section): Save current place in case DWARF code wants us
7559 to pop back to it. Handle unquoted section name as well as quoted
7560 section name. Don't crash on invalid strings.
7561 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

7673 sy_resolved and sy_resolving single bit fields.
7674 * symbols.c (symbol_new): Don't initialize sy_forward field.

8873 dropping a space immediately following an identifier.
8874 * expr.c, write.c: Rewrote assert expressions to not use multiple
8875 lines; I don't think that can be done portably.
8876 * config/tc-mips.c (macro): Use $AT if target register is zero in
8877 load instruction, which it can be for a floating point load.

8951 prototypes for all static functions. Moved existing minimal
8952 debugging format support info #ifndef OBJ_ECOFF blocks.

9001 * make-gas.com: Find obstack.obj if it's not in the current
9003 * read.c (s_ignore): Don't declare is_end_of_line. It's
9004 redundant, and triggers a VMS gcc compiler bug.
9006 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9007 current segment as an argument. (Ignored in all cases but VMS.)
9008 All callers and definitions changed.

9032 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9035 * configure.in: mips-bsd configuration was missing format spec.
9038 * Makefile.in (Makefile): Depends on configure.in.
9040 * config/tc-mips.c (append_insn): Don't check for alignment of
9041 frag in memory; alignment of instructions in section is a separate

9062 constants are accepted, but symbolic values are not. GCC will not
9063 generate the latter currently.
9065 * frags.c (frag_init): New function.
9066 (zero_address_frag, bss_address_frag): Now initialized at run
9068 * as.c (main): Call frag_init.

9358 * config-gas.com: New file. Script for VMS systems to set up the
9359 configuration to build gas for VMS, and create config.status.
9360 * make-gas.com: Redone to work with new scheme.
9361 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
9363 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
9364 will swap bytes if needed on a big endian system. Use throughout
9366 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
9367 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
9368 types of malformed stabs. Change parsing algorithm so that we are
9369 more certain of having all of the information that we need on hand.
9370 * obj-vms.c (final_forward_reference): New function, used to help
9371 resolve the data types of as many struct elements as possible
9372 when some part of the struct is not fully defined by the compiler.

9375 * obj-vms.c (VMS_write_object_file): Define all vtable psects
9376 as symbols as well in the object file. Look for external functions
9377 that start with "__vt.", and turn them into variables, since the
9378 g++ compiler is incapable of doing this.
9379 * tc-vax.c: Add '1' option for backward compatibility with older GCC
9381 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
9382 * input-scrub.c (as_where): Fix bug where as would crash if we did not
9383 have the name of the source file yet.

9389 SEG_DATA or SEG_E1 if needed.
9390 (s_lcomm): Likewise with bss_section.
9391 (s_fill): Use memset, not bzero.
9393 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

9415 (big_section, reg_section, pass1_section, diff_section,
9416 absent_section, text_section, data_section, bss_section): If
9417 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
9418 mapping to segT enum values.
9419 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
9420 if these are used or defined, if BFD_ASSEMBLER.
9421 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
9422 subseg_new split into two functions.
9423 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
9425 * as.h (volatile): Don't define if already defined.
9426 (had_errors, had_warnings): Provide prototypes for ANSI C even if
9428 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
9429 declare with format attribute for -Wformat checking.
9431 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
9433 * app.c, config/tc-*.c: Don't include read.h, since it is already
9436 * These are based on patches from Minh Tran-le
9437 <mtranle@paris.intellicorp.com>.
9438 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
9439 obj_format coffbfd and gas_target i386coff for target.
9440 (i[34]86-*-isc*): New host (uses sysv).
9441 * config/i386aix.mt: Removed (no longer used).
9442 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
9444 (LDFLAGS): Added, defined as -shlib.
9445 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
9446 * config/te-sco386.h (LOCAL_LABEL): Don't define.
9447 (DOT_LABEL_PREFIX): Define.
9448 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
9449 name rather than L0\001.

9461 (size_section): Restored sanity check.
9462 (do_relocs_for): Base section address on s_paddr rather than
9463 computing it. Adjust a29k R_IHIHALF special case to account for
9464 section paddr (used to require paddr to be zero). If there are no
9465 reclos, set s_relptr to 0. Set relocation size in object_headers.
9466 (fill_section): Always set s_vaddr here, removing
9467 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
9468 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
9469 Set STYP_INFO for .comment.

9473 H_{SET,GET}_* macros.
9474 (do_linenos_for): Set lineno size in object_headers.
9475 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
9476 set s_vaddr here. If string_byte_count remains 4, set it back to
9477 0, and only write strings out if there are some. Call
9478 fill_section before do_relocs_for and do_linenos_for.
9479 (obj_coff_section): Handle optional quoted second argument giving
9480 section characteristics.
9481 (obj_coff_bss): Added to handle .bss.

9502 (do_scrub_next_char): For \", return " not '.
9503 (symbol_chars): Now const.
9505 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
9506 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
9508 * config/obj-coff.h: Don't use #elif.
9510 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
9511 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

9540 never set segment address for SEG_E2 (.bss) and don't write out
9541 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
9542 (obj_coff_endef): Don't merge labels or symbols awaiting forward
9543 definitions, and don't merge tags with non-tags. Check for .bf
9544 rather than just checking whether the second character is b and
9545 the third character is f.
9546 (obj_coff_val): gcc can generate values which we don't handle
9547 correctly; discard information for now, since it only affects the
9548 debugging information.

9550 (yank_symbols): Don't merge labels.
9551 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

9848 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9849 sections starting from zero, rather than making them consecutive.
9850 This makes subsequent reloc calculations easier, esp if the object
9851 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9852 allocate lcomm in .data rather than in .bss. It seems that some
9853 tools can't cope with a non-zero sized bss before linkage.

9881 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
9882 .word is < -32768 or > 32767. The -J flag causes the error to be
9883 ignored. This is to catch over-sized switches generated by gcc on
9884 systems which don't support the broken .word hack.
9885 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
9886 write.c (fixup_segment): check for signed .word overflow if
9887 WARN_SIGNED_OVERFLOW_WORD.

9965 * config/tc-m68k.c (init_table): Now const. Always include 68851
9966 data, so that "bc" is available to 68040 cache instructions.
9967 Added "tt0", "tt1", and 68ec030 variants.
9968 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9969 (enum _register): Added TT0, TT1.
9970 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9971 line number correctly in "internal error" messages. Don't print
9972 architecture-mismatch message for operand errors.

9997 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9998 has already been formatted (but may still contain %-characters).
10001 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10003 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10004 written with indirection on the last two operands, which can be
10005 either data or address registers. Added a new operand type 'r'
10006 which accepts either register type. Added '(' to notend stuff in
10007 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

10318 * Makefile.in: added tooldir and program_prefix.
10320 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
10322 * write.{c,h} (fix_new): Make these declarations consistent.
10324 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
10326 * Makefile.in (strerror.o): Add rule so that broken Sun make can
10329 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10331 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10333 * expr.c (operand): if can't work out what sort of operand it is,
10334 then look through FLT_CHARS for a hint.
10336 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
10338 * Makefile.in, configure.in: removed traces of namesubdir,
10339 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10340 copyrights to '92, changed some from Cygnus to FSF.
10342 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
10343 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
10344 copyrights to '92, changed some from Cygnus to FSF.
10346 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10348 * expr.c: If an expression is single comma, then return with
10349 SEG_ABSENT rather than an error - since the sparc front end does
10350 really strange things with things like fbge,a
10352 * as.h: include bfd.h if using many sections
10353 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
10354 local labels didn't work.
10355 * listing.c (list_symbol_table): don't core dump when there's no
10357 * write.c, write.h: call fix_new with the right number of args on
10359 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
10362 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
10364 * app.c: MRI compatibility - allow single quote to start a string.
10365 * as.c: fix typo recently introduced.
10366 * as.h : Don't include aout/reloc.h - it's not right for COFF!
10367 * expr.c: Much rewriting, to accomodate MRI syntax for
10368 expressions. Also easier to read now.
10369 * listing.c: Put back defuns
10370 * read.c: modified to accept MRI syntax, put back listing pseudo
10371 ops so that an assembler built with NO_LISTING ignores list ops
10373 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
10374 machine is a SPARC or a 29K.
10375 * config/obj-aout.c: added s_sect pseudo op
10376 * config/obj-coffbfd.c: lints, set the filehdr flags right and
10377 fill in the timestamp.
10378 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
10379 anymore, define all the relocs which the tc-<x> bit will use so we
10380 can translate from them to the coff types.
10381 * config/tc-a29k.c: reloc_type isn't ane enum any more
10382 * config/tc-m68k.c: Added NO_RELOC definition.
10384 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
10386 * Makefile.in: put header files before C source for TAGS; remove
10387 references to non-existent syscalls.h.
10389 * read.c, write.c subsegs.c: back out the .bss changes.
10391 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
10393 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
10395 * a.out.h: removed.
10397 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
10399 * symbols.c (local_label_name): symbols now start with ^A.
10401 * read.c, subsegs.c, write.c obj-coff.c: added handling of
10402 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
10403 generate these sections. .align: will use NOP_OPCODE or 0
10404 for padding. This is just for being nice to the
10407 * expr.c (operand): changed to generate local label "\001L0"
10408 starting with a ^A so that it is recognized as a local label.
10410 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
10412 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
10413 i/o opcodes - inb, inw, outb and outw. string manipulation with
10414 att syntax - scmp, slod, smov, ssca, ssto.
10416 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
10417 to just after .file .
10419 In obj_crawl_symbol_chain() where it tries to put the external
10420 symbols apart, with the condition:
10421 (!S_IS_DEFINED(symbolP) &&
10422 !S_IS_DEBUG(symbolP) &&
10423 !SF_GET_STATICS(symbolP))
10424 it was moving too many symbols out. So I switch it back to the
10426 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
10428 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
10429 so that we don't use the F_RELFLG which make the linker complain
10430 that somebody has stripped the relocation info.
10432 Also, the AIX ld program require that the relocation table
10433 is sorted by r_vaddr like the standard ATT assembler does.
10435 [he also changed the sizeof(struct ...)'s into the coff
10436 style FOOSZ macros. I'm not sure this is right, but I can't
10437 remember why. xoxorich.]
10439 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
10441 * Makefile.in, configure.in, doc: use the doc. Build it, install
10444 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
10446 * read.c: white space and comments only.
10448 * configure.in: use the new atof-ns32.c for ns32k.
10450 * write.c: comment change only.
10452 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
10453 aren't yet integrated.
10455 * tc-i860.[hc]: blew off the dust. Something must still be done
10456 about conflicting relocation types.
10458 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
10461 * tc-i960.c, tc-sparc.c: white space and comments only.
10463 * tc-a29k.h: delete duplicate macro definition.
10465 * new file atof-ns32k.c copied from hack's last unreleased gas.
10467 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
10469 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
10472 * nearly everything. flush ChangeLog, package as gas-1.92.1.
10473 ChangeLog's prior to this are sketchy at best. I have logs.
10474 They just aren't ChangeLogs.
