+ (chain_frchains_together_1): Set fix_tail field.
+ (chain_frchains_together): Set frags_chained.
+
+
+ * config/tc-mips.c (s_option): Only refer to g_switch_* variables

+ or one depending on M68KCOFF.
+
+ * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
+ Define as macros instead of enumerators, since the Apollo compiler
+ can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
+ type.
+ (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
+ (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,

+
+ * listing.c (list_symbol_table): Don't print register symbols as

+
+ * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip

+ when BFD_ASSEMBLER is not defined, and all conditionals relating

+ subspaces.
+
+
+ * ecoff.c (first_proc_ptr): New static variable.

+ as well as as.new.
+
+
+ * expr.c (operand): Try to parse "0f" and "0b" sequences as
+ floating point and binary numbers respectively; if it doesn't
+ work, treat them as local labels.

+ * configure.in: Set ALL_OBJ_DEPS in output Makefile.
+
+ (Charles Bailey):
+ * vmsconf.sh: In generated file, get ".obj" suffix right, build
+ source files from other directories into objects in the current
+ directory, and specify PSECT attributes explicitly to linker.
+ Also added missing label.
+ * Makefile.in (stamp-mk.com): Reference new variable
+ VMS_OTHER_OBJS for list of non-local object files, instead of
+ listing them here.
+ (VMS_OTHER_OBJS): New variable, added more libiberty files.
+ * make-gas.com: Regenerated.

+ order.
+ (subseg_get): Clear newly allocated seginfo, set its pointer slots

+
+ * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
+ elf_tc_make_sections stuff. It was there to support PA braindamage

+ redundant with elf_tc_final_processing.
+
+
+ * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the
+ manufacturer.
+
+
+ * config/tc-mips.c (mips_ip): For case 'o', when generating

+ (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
+ value into the file if the fixup will not generate a reloc.
+
+
+ * config/tc-sparc.c (s_reserve): If section passed isn't bss,
+ don't spew remainder of input file in error message.
+ (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error

+
+ * doc/Makefile.in (install-info-as, install-info-gasp): New
+ targets, now explicitly checking $(srcdir) for info files.
+ (install-info): Depend on both of them; do nothing more.
+
+
+ * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
+
+
+ * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED

+
+ * config/tc-ppc.c (ppc_size): New static variable.
+ (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.

+
+ * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
+ RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),

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

+ but it should eventually be converted to generate the insn itself
+ and call emit_insn directly.
+ (emit_load_unal, emit_store_unal, emit_byte_manip_r,
+ emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,

+ the value can't be resolved.
+
+
+ * config/tc-mips.c (md_parse_option): For -membedded-pic, force
+ the -G value to 0x7fffffff. For SVR4 PIC options, don't call
+ bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
+ -membedded-pic.
+ (mips_force_relocation): New function.
+ (md_apply_fix): Set fixP->fx_done appropriately.

+ (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If

+ -non_shared to use NO_PIC (this is how the Irix 5 assembler
+ works). Do not permit -G with SVR4_PIC.
+ (s_abicalls): Warn if -G was used, and force -G 0.
+ (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
+ anything but a.out, not just for ELF. For ECOFF, don't generate a
+ BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
+
+ * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
+
+
+ * config/tc-hppa.c (create_new_space): Use ints, not chars as
+ parameters to avoid losing when compiling with HP CC.
+ (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
+
+
+ * Makefile.in (config-stamp): If `defs' is defined, emit a
+ preprocessor directive to create a macro named by this value into
+ config.new; don't explicitly go for BFD_ASSEMBLER.

+ (dump_section_relocs): Note whether a symbol is a section symbol
+ or not.
+ (adjust_reloc_syms): For now, always supply an absolute symbol for
+ fixups without symbols but not yet `done'. Use section_symbol to

+ (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
+ reloc is not a section symbol and is not in the symbol table.
+ (set_symtab): New function, broken out from write_object_file.
+ Counts symbol table instead of relying on an earlier count.
+ (write_object_file): Call set_symtab, but do it after potentially
+ invoking the *_frob_file macros. Don't bother counting symbols.
+ Call symbol_remove, instead of expanding it in place. Moved the
+ conditionalized `object_file_size' declaration down to
+ conditionalized block where it's used. When using the absolute
+ symbol for a fixup without a symbol, set sy_used_in_reloc.
+ (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
+ the correct symbol for the absolute section.
+
+ * subsegs.c (section_symbol): Use symbol_new instead of
+ symbol_make, since we may want it to go into the symbol table.
+ Make the new symbol have internal linkage. If
+ obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
+ symbol with the newly created GAS symbol.
+ (obj_sec_sym_ok_for_reloc): Default to always returning 0.
+ * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

+ (sparc_ip, label "immediate"): Reject constants for pcrel
+ instructions only if the relocation type indicates a "call"
+ instruction and the offset is within range of a "jmpl %g0". If
+ it's not in range, use the absolute section symbol plus an offset.
+ (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
+ _BASE13 cases.
+ (tc_gen_reloc): Permit BFD_RELOC_SPARC13.

+ * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
+ MANY_SEGMENTS).
+
+ * configure.in: Eliminated all targets using obj-coff but not
+ defining BFD_ASSEMBLER; I think all such targets that are
+ supported will be matched by real CPU-OS combinations earlier in
+ the case statement.
+ (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
+ some comments about the dpx2 configuration, but left it disabled,
+ since it couldn't be reached before.
+ (target a29k-amd-ebmonold): Deleted.
+
+
+ * config/tc-hppa.c (pa_import): Correctly handle importing of an
+ already defined symbol.
+
+

+ the 'j' operand if there are no further alternatives for this
+ instruction.
+
+ * config/obj-coffbfd.c (adjust_stab_section): Initialize
+ stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
+ is not SEG_UNKNOWN rather than checking whether it is >= 0.
+
+ * config/tc-mips.c (mips_align): Take new argument, label, and use
+ it instead of global insn_label.
+ (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
+ call to mips_emit_delay and pass it to mips_align.
+
+
+ * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
+
+ * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
+ argument to a .callinfo directive. Don't loop forever on errors.
+
+ * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
+ use pre-defined registers as arguments.
+
+
+ * write.c (write_object_file): Check both S_IS_LOCAL and
+ S_IS_EXTERNAL when deciding whether to discard a symbol.
+
+ * config-gas.com: Scan Makefile.in, not version.c, for current
+ version number. Delete all versions of temp files when finished
+ with them. Create config.h.
+
+ * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
+ values to reduce number of lookups with S_GET_VALUE. Skip debug
+ symbols to avoid "a really nasty bug". (From Holger Teutsch,
+ (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
+ field. (Also from Holger Teutsch.) Watch for a would-be register
+ mask that spans frags.
+
+ * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
+ this_base, not line_base. (Patch from Andreas Arens,
+
+ * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
+ look local if they're exported or undefined. Used to be done for
+ i960 only.
+
+ * read.c (s_lcomm, s_comm): Print symbol name being redefined.
+ Get it from the looked-up symbol, instead of using the string from
+ the input stream, which is no longer null-terminated.
+ (LEX_PCT): New macro, defaults to 0.
+ (lex_type): Use it for `%'.
+
+ * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
+ (vip_op): Now static, and returns void. Callers changed. Added
+ forward decl.
+ (vip): Ditto. Call as_fatal directly if a program bug is
+ detected.
+ (op_hash): Let default initialization suffice.
+
+ * Makefile.in (literal.o): Provide dependencies.
+
+ * configure.in: Set new makefile variable OPCODES_LIB.
+ * Makefile.in (LIBS): Use it.
+
+ * Makefile.in (make-gas.com, stamp-mk.com): New targets.
