with the preceding instruction even if .set nobopt has been seen.
.set nobopt actually controls whether to bring up an instruction
from the branch target, which gas does not currently support.
BFD_ASSEMBLER is not defined, and all conditionals relating to such code. No
such targets remain.
Fixes for stabs-in-coff:
* config/obj-coff.c: Include subsegs.h.
(coff_frob_section): New function.
(obj_coff_init_stab_section): New function.
* config/obj-coff.h (obj_coff_init_stab_section, coff_frob_section): Declare.
(obj_frob_section): New macro; uses coff_frob_section.
(INIT_STAB_SECTION): New macro; uses obj_coff_init_stab_section.
defaults for defined, private, and spnum fields for the
$TEXT$ and $PRIVATE$ spaces. Do not clobber spnum. Do
not reset the segment if just updating a space.
(pa_spaces_begin): Set BFD section flags for all built-in
subspaces.
(add_procedure): Set first_proc_ptr if it hasn't been set.
(ecoff_build_lineno): If the first procedure does not start at
address zero, insert a dummy line to compensate.
* configure.in: Set ALL_OBJ_DEPS in output Makefile.
Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu> (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.
* config/ho-vms.h (unlink): Define as delete.
* config-gas.com: Fix quoting on TARGET_CANONICAL definition. Delete files
before creating them.
* config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
certain cases of 'i', 'j' and 'o'. Change 'u' to take an
argument, the reloc type.
(load_register): Pass reloc type to macro_build for 'u'.
(macro): Likewise. For M_LA_AB permit a difference expression
when generating embedded PIC code between an arbitrary symbol and
a symbol in the .text section.
(mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
BFD_RELOC_PCREL_LO16 to be emitted.
(md_apply_fix): Check that most relocs are not PC relative.
Handle BFD_RELOC_PCREL_HI16_S and BFD_RELOC_PCREL_LO16.
(tc_gen_reloc): Change #error to as_fatal. Handle
BFD_RELOC_PCREL_LO16 and BFD_RELOC_PCREL_HI16_S.
* subsegs.c (subsegs_begin): Call memset with args in the correct
order.
(subseg_get): Clear newly allocated seginfo, set its pointer slots
to NULL instead of 0.
Fixes a problem observed in sparc-lynx progressive.
macro_build for nori case.
(SWITCH_TABLE): Define.
(mips_force_relocation): Force a relocation for a switch table
entry.
(md_apply_fix): Write switch table entry value into file.
(tc_gen_reloc): Use BFD_RELOC_GPREL32 for a switch table entry,
and set the addend to the difference between the reloc address and
the subtrahend.
(elf_tc_make_sections): Likewise.
(hppa_tc_make_sections, hppa_tc_symbol): Delete extern decls.
* config/tc-hppa.c (hppa_tc_make_sections): Delete function.
(hppa_tc_symbol): Likewise.
* config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
elf_tc_make_sections stuff. It was there to support PA braindamage
which has been fixed, and in the case of elf_tc_make_sections is
redundant with elf_tc_final_processing.
embedded PIC code, accept the difference between two local symbols
as being constant.
(mips_force_relocation): Only force a reloc to be generated for a
PC relative fixup.
(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.
flag rather than signedp field. Only permit extended range if
PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
(ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
(md_begin): If an instruction has a size specific flag set, only
add it if we are assembling that size.
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
do the right thing.
(T12): New macro.
(emit_insn): New function.
(md_assemble): Call it.
(alpha_force_relocation): Handle BFD_RELOC_26, for call_pal instructions.
(lituse_pending): New variable. Set by anything that generates a LITERAL
reloc, cleared by anything that generates a LITUSE reloc, tested by code that
might want to emit a LITUSE reloc.
(emit_unaligned_io): New function. Currently calls md_assemble, 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, emit_bis_r): Likewise.
(alpha_ip, case 'I'): Handle with BFD_RELOC_23.
(alpha_ip, label get_macro): Don't emit the final instruction if the opcode is
zero.
(alpha_ip, case 'B', subcase 'd'): New case, for subword and unaligned memory
access macros.
(md_apply_fix): Handle BFD_RELOC_26. Generate an error message if the value
can't be resolved.
(mips_pic): Change from int to enum mips_pic_level. Change all
uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
(load_address): Handle EMBEDDED_PIC.
(macro): Handle EMBEDDED_PIC in all PIC cases.
(md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
-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.
is called.
(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 get the symbol,
instead of going directly for abs_symbol.
(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.
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.
with S_GET_VALUE. Skip debug symbols to avoid "a really nasty bug". (From
Holger Teutsch, holger@botbso.rhein-main.de.)
(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/alpha-opcode.h (ldif, ldig, ldis, ldit): New patterns.
* config/tc-alpha.c (lit8_sec, lit4_sec, lit8_sym, lit4_sym): New variables.

(obj_coff_section): Declare.
(obj_pseudo_table): Make it available only if MANY_SECTIONS.
(obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this work. It
still doesn't. It now fails to compile, instead of silently compiling to do
nothing.
* config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if MANY_SECTIONS.
(OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits a warning.

little-endian object files.
* config/tc-i960.c (md_reloc_size): Don't define at all if BFD or
BFD_ASSEMBLER is defined.

normal 32-bit relocations.
(md_apply_fix): For callx relocations, store zero.
(tc_bout_fix_to_chars): Store symbol idx for all callx relocations, regardless
of link-relax setting.
(tc_coff_fix2rtype, tc_coff_sizemachdep): New functions.
(i960_handle_align) [! OBJ_BOUT]: If link-relax option is selected, print an
error message and clear it.
* config/tc-i960.h (BFD_ARCH, COFF_FLAGS, COFF_MAGIC, TC_COUNT_RELOC,
TC_COFF_FIX2RTYPE, TC_COFF_SIZEMACHDEP, tc_fix_adjustable): New macros.
(tc_coff_fix2rtype, tc_coff_sizemachdep): Declare.
(objdump_start): Deleted unused proc.
(objdump_start_common): Merged into objdump_start_no_subdir.
* gas/alpha/fp.exp: Use objdump instead of objdump_start_no_subdir, since the
former actually waits for objdump to finish. Specify .rdata section only.
Make comment indicate Alpha architecture rather than SPARC.
* gas/alpha/fp.d: Omit .reginfo patterns. Just use "." to match
against ASCII code 0x2a ("*", special in regexp).

OBJ_COFF specific "bi" and "ei".
(md_parse_option): Fix handling of -u. Make -m601 set
PPC_OPCODE_601. If OBJ_ELF, accept -V and -Q.
(ppc_set_cpu): New function.
(ppc_arch): New function.
(md_begin): Call ppc_set_cpu.
(ppc_insert_operand): For a signed operand accept an unsigned
value, for IBM compatibility.

BFD_RELOC_8.
(2) move explanation of new MIPS options from summary section to MIPS-options
section; add summaries in appropriate spots.
(3) usual minor rephrasing in passing.
* config/obj-coffbfd.c (obj_coff_init_stab_section): Use memset
instead of memcpy to zero the initial stab symbol, duh.
* config/obj-elf.c (obj_elf_init_stab_section): Ditto.
* config/obj-som.c (obj_som_init_stab_section): Ditto.
precedence questions.
(addr32): New static variable.
(md_parse_option): Set it for "-32addr".
(load_symbol_address): If addr32 is set, use ldl instead of ldq.
return type to valueT, to agree with tc.h.
(alpha_do_align): Local static array nop_pattern is now unsigned
char, to avoid overflow warnings.
* tc-alpha.h (md_section_align): Delete declaration.
* obj-ecoff.c (ecoff_frob_file): Ensure that ecoff_data for
output bfd is non-null before indirecting through it.
Crock to get GP set right:
* tc-alpha.c (alpha_frob_ecoff_data): Renamed from alpha_frob_file.
* tc-alpha.h (tc_frob_file): Macro deleted.
* obj-ecoff.c (ecoff_frob_file) [TC_ALPHA]: Call alpha_frob_ecoff_data, then
fill in optional-header info with gp value and register masks.
* config/obj-coffbfd.c (obj_coff_init_stab_section): Zero the
initial stab symbol after allocating it.
* config/obj-elf.c (obj_elf_init_stab_section): Ditto.
This fixes a critical bug observed in Q4 for Lynx.
* subsegs.h (struct frchain): If BFD_ASSEMBLER, added new fields
fix_root and fix_tail.
(segment_info_type): If BFD_ASSEMBLER, don't define fix_tail
field.
* write.c (fix_new_internal): If BFD_ASSEMBLER, set fix_rootP and
fix_tailP based on frchain_now, not seg_info (now_seg).

* subsegs.c (subseg_change): Don't clear fix_tail field.
(subseg_get): Likewise.
* literal.c (add_to_literal_pool): Look through the relocs via
frchain_now, not seginfo.

fragP->fr_var, and cast it to long.
ecoff_undefined.
(ecoff_frob_symbol): Don't check ecoff_undefined.
(ecoff_build_symbols): Get size of an undefined symbol from
sym->ecoff_extern_size, not S_GET_VALUE (sym).
declare it differently.
(Actually, the only use is in xmalloc; if xmalloc didn't also zero out the
region of memory, I'd delete the function altogether and use the libiberty
version...)
dot_bss_symbol): Don't define if BFD_ASSEMBLER.
(obj_symbol_to_chars): bfd_coff_swap_aux_out now takes more
arguments.
(coff_line_base): Renamed from line_base. Changed all uses.
(coff_add_linesym): Renamed from add_line_sym. Made non-static.
Changed all uses.

This version formats cleanly under makeinfo, and in Cygnus format.
Default FSF format works without error, but tables of machine
instructions for some machines have stupid page boundaries (FSF
version uses larger page size).
