xcoffout.c (xcoffout_declare_function): Add documentation. 

	* xcoffout.c (xcoffout_declare_function): Add documentation.
	* rs6000.c (num_insns_constant_wide): Use TARGET_POWERPC64 not
	TARGET_64BIT.  Compare constant to -1, not bit pattern.
	(easy_fp_constant): Use TARGET_POWERPC64 not TARGET_64BIT.
	(expand_block_move): Allow 8 DImode loads for PowerPC64.  Fix
	gen_movsi typos.
