table if it's already been set in the output bfd.
(symbol_begin) [! EMIT_SECTION_SYMBOLS] [RELOC_REQUIRES_SYMBOL]: Don't use
bfd_abs_section.symbol for gas absolute symbol.
* 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.
