* config/mips-opcode.h: Moved to opcode/mips.h.
* config/tc-mips.c: Include opcode/mips.h rather than
mips-opcode.h.
(append_insn): An extra NOP is only needed after instructions
which set HI or LO, not after instructions which read it.
(macro_build, mips_ip): Support new 'E', 'G' and 'B' arguments.
(macro): cfc1 and ctc1 now take "t,G" rather than "t,d".
* config/tc-mips.h (struct mips_opcode): Don't define.
* config/mips-big.mt, config/mips-lit.mt (TARG_CPU_DEPENDENTS):
Set to $(srcdir)/../include/opcode/mips.h.
Get the MIPS assembler up to speed with other gas changes:
* config/obj-ecoff.c (ecoff_set_vma, ecoff_frob_symbol):
Removed; don't change the symbol value.
(ecoff_build_symbols, ecoff_build_procs, ecoff_frob_file): Use
bfd_asymbol_value rather than S_GET_VALUE to include section
vma in symbol value.
(ecoff_frob_file): Ignore BSF_SECTION_SYM symbols, since ECOFF
doesn't output them. Set the vma of sections.
* config/obj-ecoff.h: Don't define obj_frob_symbol.
* config/tc-mips.c (tc_gen_reloc): Adjustment by section vma is no
longer necessary.
(various): use valueT rather than long.
