mips_cpu is 5000, set interlocks and cop_interlocks.
(mips_ip): Give a better error message if the ISA level is wrong.
(md_parse_option): Recognize -mcpu=[v][r]5000.
* config/tc-mips.c (load_register): Remove unnecessary code that
was causing the high 32bits of 64bit constants to be lost.
Fixes PR10503. The compiler was producing the assembler code:
dli $3,0xfffffffffffff
when constructing the softfloat library. Unfortunately it was being
incorrectly assembled.
* config/tc-mips.c: Added cop_interlocks, to avoid NOP insertion
between co-processor comparisons and branches for the VR4300.
The preliminary documentation was slightly unclear on this issue, but
NEC have confirmed that there is an interlock within the CPU.
(mips_target_format): If mips_64, return elf64 targets rather than
elf32 ones.
(md_longopts): Add "32" and "64".
(md_parse_option): Handle -32 and -64.

a 4 byte one.

new fixup to mips_hi_fixup_list. Change all callers.
(mips_ip): Set imm_unmatched_hi when appropriate.

(s_extern): Don't declare.

expression.

(macro): Handle mips_big_got for M_LA_AB, M_JAL_A, and load and
store macros.

(mips_emit_delays): Likewise.
(mips_ip): Only permit INSN_4010 instructions if mips_4010.
(md_longopts): Add "m4010" and "no-m4010".

(md_parse_option): In case 'g', set mips_debug to debugging level.
(mips_local_label): New function.
* tc-mips.h (LOCAL_LABEL): Call mips_local_label.
(mips_local_label): Declare.
PR 6978.
* config/obj-multi.h (obj_frob_symbol, obj_frob_file, S_GET_SIZE, S_SET_SIZE,
S_GET_ALIGN, S_SET_ALIGN, obj_copy_symbol_attributes, OBJ_PROCESS_STAB): New
macros.
* config/tc-mips.c: Protect against redefining them also when including
obj-elf.h. Test only OBJ_ELF for including elf/mips.h.
* config/tc-mips.c (mips_target_format): Changed to a function, checking flavor
and byte order at run time.

(md_begin, mips_ip, md_parse_option, s_change_sec, s_option, s_abicalls,
nopic_need_relax): Check USE_GLOBAL_POINTER_OPT at run time, instead of
compiling conditionally on GPOPT.
(GPOPT): Don't define.
(md_shortopts): Always include -G.
(RDATA_SECTION_NAME): Select at run time.
(md_begin): Test for ELF format at run time instead of compile time.
(mips_ip, s_change_sec): Ditto.
(md_parse_option, cases OPTION_CALL_SHARED and OPTION_NON_SHARED): Ditto.
(OPTION_CALL_SHARED, OPTION_NON_SHARED, mips_regmask_frag): Define
unconditionally.
(nopic_need_relax): New static function, split out from
md_estimate_size_before_relax.
(md_estimate_size_before_relax): Call it.
(load_address, macro): In NO_PIC branches, if nopic_need_relax returns nonzero,
don't attempt GP optimization.

* as.c (main): Call frag_init before subsegs_begin.
* frags.c (frag_append_1_char): New function.
* frags.h (frag_append_1_char): Declare it.

* subsegs.h (struct frchain): New field frch_obstack, intended to eventually
replace global `frags' obstack.
* subsegs.c (subseg_set_rest): Use frag_now_fix instead of accessing `frags'
directly. Initialize fields of new frchainS explicitly instead of with memset.
* config/obj-coff.c (obj_coff_ln) [!BFD_ASSEMBLER]: Use frag_now_fix.

already set. For -mcpu=, just set mips_cpu, not mips_isa.
