(mips_ip): Use RDATA_SECTION_NAME, not .rdata.
(s_change_sec): Likewise.
going through md_number_to_chars. This permits handling symbolic

* 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"

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.

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.

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.

when generating embedded PIC code between an arbitrary symbol and

BFD_RELOC_PCREL_LO16 to be emitted.

entry.
(md_apply_fix): Write switch table entry value into file.

(hppa_tc_make_sections, hppa_tc_symbol): Delete extern decls.
* config/tc-hppa.c (hppa_tc_make_sections): Delete function.
(hppa_tc_symbol): Likewise.

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.

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.

add it if we are assembling that size.
branch with an instruction that uses $at, in case the branch is
later expanded.

(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.

access macros.

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.
