Ian Lance Taylor 8ff6f40e74 * read.c (read_a_source_file): If NO_PSEUDO_DOT is defined, look
up opcodes as pseudo-ops even if they don't start with '.'.
	* config/tc-m88k.h (NO_PSEUDO_DOT): Define.
	* config/tc-m88k.c (md_assemble): Removed special pseudo-op
	handling.
	(md_apply_fix): Set fx_offset to the upper 16 bits of the reloc.
	Output the low 16 bits for RELOC_HI16, not the high 16 bits.
	* config/obj-coffbfd.c (do_relocs_for): If TC_M88K, set the
	r_offset field of the reloc to the fixup offset.
	(fixup_segments): If TC_M88K, don't warn about fixup overflows.
	* doc/as.texinfo: Minor updates.
