disable warning about all NOPS that the assembler generates.
(macro): Warn NOPS generated only if warn_nops is not 0.
(md_shortopts): Add `n'.
(md_parse_option): Set warn_nops to 1 for `n'.
* config/tc-mips.c (md_apply_fix): Don't adjust common
extern/weak symbols for ELF.

(my_getExpression): Likewise.
(md_apply_fix): Likewise. Use "valueT" rather than "long" for "value".
(mips16_extended_frag): Remove code concerned with avoiding
locking in a frag address now that symbols are not finalized until
relaxation is complete. Cater for first relaxation pass having
bogus addresses. Use relax_marker to reliably determine whether a
symbol frag has been reached on the current pass.
* config/tc-mips.c: Support ELF64 for traditional MIPS targets.
* Makefile.am: (TARG_ENV_HFILES): Add tc-mips.h.
* Makefile.in: Regenerated.

* config/tc-mips.c (mips_target_format): Return elf32-tradbigmips or
elf32-tradlittlemips for traditional mips targets.
* config/tc-mips.c (md_estimate_size_before_relax): Duplicate the
test for Link Once sections as in adjust_reloc_syms.
* config/te-tmips.h: New file for traditional mips targets. Define
TE_TMIPS.

mips_elf_next_lo16_relocation, and generalize to look
for any relocation type.

(mips_rtype_to_howto): Likewise.
(mips_elf_calculate_relocation): Handle new relocs.
(_bfd_mips_elf_relocate_section): REL_HI16/REL_LO16 relocs
are paired. The addend for R_MIPS_GNU_REL16_S2
is shifted right two bits.
In gas/:
* config/tc-mips.c (mips_ip): Don't put stuff in .rodata
when embedded-pic.
* config/tc-mips.c (SWITCH_TABLE): The ELF embedded-pic
implementation doesn't have special handling for switch
statements.
(macro_build): Allow for code in sections other than .text.
(macro): Likewise.
(mips_ip): Likewise.
(md_apply_fix): Do pc-relative relocation madness for MIPS ELF.
Don't perform relocs if we will be outputting them.
(tc_gen_reloc): For ELF, just use fx_addnumber for pc-relative
relocations. Allow BFD_RELOC_16_PCREL_S2 relocs when
embedded-pic.

expected failure.
In include/elf:
* mips.h: Add R_MIPS_GNU_REL_HI16, R_MIPS_GNU_REL_LO16,
R_MIPS_GNU_REL16_S2, R_MIPS_PC64 and R_MIPS_PC32 relocation
numbers.

mips_emit_delays,macro_build,load_register,load_addresss,
macro,macro2,mips_ip,s_cprestore,s_cpadd): Simplify
and/or use new ISA_xxx macros in expressions involving
ISA, particularly mips_opts.isa.
