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. + * config/obj-ecoff.c (ecoff_build_symbols, ecoff_build_procs, ecoff_frob_files): Consistently use S_GET_VALUE rather than bfd_asymbol_value.
