	* config/tc-mips.h (tc_frag_data_type, TC_FRAG_TYPE): New.
	* config/tc-mips.c: Use signed add for n32 address arithmetic.
	(append_insn): When filling delay slots with instructions
	that have fixups that tc_gen_reloc might consider modifyable
	in variant frags, start a new frag.
	(load_address): Generate GOT_DISP with of without offset
	depending on whether symbol is local.  For -xgot, use
	GOT_PAGE/GOT_OFST or GOT_HI16/GOT_LO16.
	(macro) <M_DLA_AB, M_LA_AB>: Likewise.
	<M_JAL_A>: In NewABI, use CALL16 or GOT_DISP for small got,
	CALL_HI16/CALL_LO16 or GOT_PAGE/GOT_OFST for big got.
	<ld_st>: In NewABI with small got, always use
	GOT_PAGE/GOT_OFST, with the latter in the load/store
	instruction.  With big got, use GOT_HI16/GOT_LO16 or
	GOT_PAGE/GOT_OFST.
	(tc_gen_reloc): Adjust variant frags with GOT_DISP in NewABI.
	Add tc_frag_data.tc_fr_offset to addends.  Decay CALL16,
	GOT_OFST and GOT_DISP to GOT_DISP in NewABI.
	(md_convert_frag): Use memmove for safe copying of overlapping
	regions.

	(M68HC11-Modifiers): New section for operand modifiers.
	(M68HC11-Directives): New section for specific assembler directives.

	64-bit addresses that are not sign extensions of 32 bits only if
	we don't support 64-bit address constants.

	as 32 or 64 bits if addresses are 32-bit wide but registers are
	64-bit wide.

2003-04-05  Stephane Carrez  <stcarrez@nerim.fr>

	* config/tc-m68hc11.c (M6811_OP_CALL_ADDR): New internal define.
	(M6811_OP_PAGE_ADDR): New internal define.
	(get_operand): New modifier %page and %addr to obtain page and 
	address part of a far-function.
	(fixup8): Use BFD_RELOC_M68HC11_PAGE for a %page modifier; don't 
	complain on overflow for the BFD_RELOC_M68HC11_PAGE and truncation
	relocs.
	(fixup16): Use BFD_RELOC_M68HC11_LO16 for a %addr modifier.

	STATE_UNDEXED_OFFSET types when the symbol is not absolute.
	(tc_m68hc11_fix_adjustable): Check for BFD_RELOC_M68HC11_LO16
	instead of BFD_RELOC_LO16; temporarily make the BFD_RELOC_32
	on the symbol itself so that DWARF2 strings are merged correctly.
