+
+ * write.c (print_fixup): Use TC_FIX_DATA_PRINT (if defined) to
+ print out MD fields of fix.
+ * frags.c (frag_var, frag_variant): Use TC_FRAG_INIT macro (if
+ defined) to initialize MD fields in frag.
+ * as.h (struct frag, ns32k support): Rename ns32k to fr_ns32k.
+ Delete pcrel_adjust. Add fr_opcode_fragP, fr_opcode_offset.
+ * config/tc-ns32k.h: Add comments. Remove obsolete
+ BFD_FAST_SECTION_FILL definition, change prototypes for
+ fix_new_ns32k and fix_new_ns32k_exp to add new arguments
+ opcode_frag and opcode_offset and remove pcrel_adjust.
+ (TC_FIX_TYPE): add opcode_fragP and opcode_offset fields.
+ (TC_FIX_DATA_PRINT): new macro to print out TC_FIX_TYPE.
+ (TC_FRAG_INIT): new macro to initialize machine dependent field in
+ frags.
+ (frag_opcode_frag, frag_opcode_offset, frag_bsr): macros to access
+ MD fields in frag structure.
+ (fix_im_disp, fix_bit_fixP, fix_opcode_frag, fix_opcode_offset,
+ fix_bsr): macros to access MD fields in fix structure.
+ * config/tc-ns32k.c: Avoid overlength lines. Align comments. Don't
+ use struct opcode_location as these fields are now in the frag
+ structure.
+ (convert_iif): Call frag_more as it is needed instead
+ of trying to allocate for the whole insn. Avoid call of frag_more
+ with negative argument.
+ (md_pcrel_adjust, md_fix_pcrel_adjust, md_apply_fix,
+ md_estimate_size_before_relax, md_pcrel_from,
+ tc_aout_fix_to_chars): use accessor macros to get md fields in fix
+ and frag structures.
+ (fix_new_ns32k, fix_new_ns32k_exp): add new arguments opcode_frag and
+ opcode_offset and remove pcrel_adjust.
+ (convert_iif, cons_fix_new_ns32k): call fix_new_ns32k,
+ fix_new_ns32k_exp with changed arguments.

- * tc-mips.c (md_begin): Reorganize setting of default values so
- that mips_cpu depends on TARGET_CPU, and mips_opts.isa depends on
- mips_cpu.
- (md_parse_option): Remove all code that sets defaults; md_begin
- handles all of this now.
