	PR target/20813
	* config/rs6000/default64.h (TARGET_DEFAULT): Add MASK_PPC_GFXOPT.
	* config/rs6000/rs6000.c (processor_target_table): Rename rs64a to
	rs64.  Add MASK_PPC_GFXOPT to powerpc64 and rs64.
	(rs6000_init_libfuncs): Set TFmode optabs to xlq names if
	TARGET_XL_COMPAT.
	* doc/invoke.texi (PowerPC options): Change rs64a to rs64.
