* write.c (print_fixup): Use TC_FIX_DATA_PRINT (if defined) to

Browse Source 
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.
