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.
