	Backport from trunk
	2015-03-03  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR 65138/target
	* config/rs6000/rs6000-cpus.def (powerpc64le): Add new generic
	processor type for 64-bit little endian PowerPC.

	* config/rs6000/rs6000.c (rs6000_option_override_internal): If
	-mdebug=reg, print TARGET_DEFAULT.  Fix logic to use
	TARGET_DEFAULT if there is no default cpu.  Fix -mdebug=reg
	printing built-in mask so it does not pass NULL pointers.

	* config/rs6000/rs6000-tables.opt: Regenerate.

	* doc/invoke.texi (IBM RS/6000 and PowerPC options): Document
	-mcpu=powerpc64le.

	Backport from trunk
	2015-01-19  David Edelsohn  <dje.gcc@gmail.com>

	* config/rs6000/default64.h: Include rs6000-cpus.def.
	(TARGET_DEFAULT) [LITTLE_ENDIAN]: Use ISA 2.7 (POWER8).
	(TARGET_DEFAULT) [BIG_ENDIAN]: Use POWER4.
	* config/rs6000/driver-rs6000.c (detect_processor_aix): Add POWER7
	and POWER8.
	* config/rs6000/linux64.h (PROCESSOR_DEFAULT64): Always default to
	POWER8.
	* config/rs6000/rs6000.c (rs6000_file_start): Emit .machine
	pseudo-op to specify assembler dialect.
