* obj-coffbfd.h (TARGET_FORMAT) [TC_I960]: Ditto.
* obj-coff.c (coff_frob_section): Round up the size of every section to a
multiple of the alignment, so that BFD doesn't surprise us.
Eliminate many simple differences between the two COFF back ends:
* obj-coffbfd.c: Removed all uses of DEFUN and DEFUN_VOID. Made minor
stylistic changes, deleted some register declarations.
(stack_top): Deleted.
(symbol_to_chars): Use absolute_section and reg_section instead of the
corresponding SEG_* symbols.
(obj_coff_endef, tag_find_or_make, fixup_segment): Likewise.
(stack typedef, stack_init, stack_delete, stack_push, stack_pop): Moved to just
after pseudo-op table. All functions now static.
(stack_delete): Removed declaration.
(tag_init, tag_insert, tag_find_or_make, tag_find): Moved to just after stack
functions.
* obj-coffbfd.h: Reordered some declarations and macros.
(stack_init, stack_delete, stack_push, stack_pop): Don't declare.
(stack typedef): Deleted.
(SYMBOLS_NEED_BACKPOINTERS): Always undef then define; don't test.
(SYM_AUXENT): New macro.
(SA_GET_*, SA_SET_*): Define in terms of SYM_AUXENT when feasible.
(SF_GET_*, SF_SET_*): Define in terms of SF_GET when feasible.
(SA_GET_SYM_TAGNDX, SA_GET_SYM_ENDNDX, SA_SET_SYM_TAGNDX, SA_SET_SYM_ENDNDX,
object_headers typedef, data_section_header, text_section_header): Delete
non-BFD_HEADERS versions, since we always define that symbol now.
* obj-coff.c (stack_top): Deleted.
(obj_coff_endef, obj_coff_dim, obj_coff_line, obj_coff_size, obj_coff_scl,
obj_coff_tag, obj_coff_type, obj_coff_val): Change argument name from "ignored"
to "ignore".
(obj_coff_val): Use frag_now_fix.
(obj_pseudo_table): Removed IGNORE_DEBUG version, since it doesn't get used.
(stack typedef, stack_init, stack_delete, stack_push, stack_pop): Moved to just
after pseudo-op table. All functions now static.
(tag_init, tag_insert, tag_find_or_make, tag_find): Moved to just after stack
functions.
* obj-coff.h: Reordered some declarations and macros. Protected against
multiple inclusions.
(stack_init, stack_delete, stack_push, stack_pop): Don't declare.
(stack typedef): Deleted.
(SYMBOLS_NEED_BACKPOINTERS): Always undef then define; don't test.
(stdoutput): Deleted declaration.
(TARGET_FORMAT) [TC_I386]: Don't define if already defined.
BFD_ASSEMBLER.
* subsegs.c (subseg_change): Initialize fix_tail field.
(subseg_get): Likewise.
* write.c (frags_chained): New static variable.
(fix_new_internal): If frags_chained is set, use fix_root and
fix_tail from seg_info (now_seg), rather than frchain_now.
(chain_frchains_together_1): Set fix_tail field.
(chain_frchains_together): Set frags_chained.
REGISTER_PREFIX_OPTIONAL, if defined, or zero.
(m68k_reg_parse): If flag_reg_prefix_optional is set, permit register prefix to
be absent.
(m68k_ip_op): Accept `&' also for immediate constants.
(insert_reg): Don't bother with (two!?) sanity checks of the symbol table when
inserting each register.
(m68k_parse_long_option): New function. Set flag_reg_prefix_optional if
"register-prefix-optional" is passed.
* tc-m68k.h (REGISTER_PREFIX): Always define if not already defined.
(OPTIONAL_REGISTER_PREFIX): Don't define.
(REGISTER_PREFIX_OPTIONAL): If not already defined, define as zero
or one depending on M68KCOFF.
Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
* 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, R_DIR16, and
R_DIR32 relocs.
* tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC): Use Apollo versions.
[TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is, do include the
optional header for Apollo target.
(COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
* tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%' can be used within a
label name.
* tc-m68k.h (m68k_init_after_args): Declare.
(tc_init_after_args): Define as m68k_init_after_args.
* tc-m68k.c (m68k_init_after_args): New function, containing one-shot code from
md_assemble. Added warning for combination of 68040 and 68851.
(md_assemble): Startup-time code deleted.
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.
