* config/tc-hppa.h (tc_frob_label): Define.
* config/tc-mips.c: Many changes to support simple assembler
optimization.
(insn_label, prev_insn, prev_prev_insn, dummy_opcode,
prev_insn_valid, prev_insn_frag, prev_insn_where,
prev_insn_fixp, prev_insn_is_delay_slot): New static
variables.
(insn_uses_reg, mips_no_prev_insn, mips_emit_delays,
mips_align, s_stringer, s_mips_space): New static functions.
(mips_define_label): New global function.
(md_pseudo_table): For "ascii", "asciz", "asciiz", call
s_stringer. Changed argument to float_cons from 0 or 1 to 'f'
or 'd'. For "space" call s_mips_space.
(md_begin): Call mips_no_prev_insn.
(append_insn): Only insert necessary NOP instructions.
(macro): Call mips_emit_delays before setting mips_noreorder.
Increment and decrement mips_noreorder rather than using
save_reorder_condition. Don't bother to use noreorder in
M_L_DOB and M_L_DAB, since append_insn will not insert a NOP.
(md_atof): Handle floating point numbers correctly for both
big and little endian targets.
(s_align, s_cons): Call mips_align rather than frag_align.
(s_change_seg, s_cons): Call mips_emit_delays.
(s_float_cons): Let float_cons do the work.
(s_mipsset): Call mips_emit_delays when setting noreorder.
* config/tc-mips.h (tc_frob_label): Define to be
mips_define_label.
