[gcc/testsuite]
2014-03-12  Michael Meissner  <meissner@linux.vnet.ibm.com>

	* gcc.target/powerpc/p8vector-int128-1.c: New test to test ISA
	2.07 128-bit arithmetic.
	* gcc.target/powerpc/p8vector-int128-2.c: Likewise.

	* gcc.target/powerpc/timode_off.c: Restrict cpu type to power5,
	due to when TImode is allowed in VSX registers, the allowable
	address modes for TImode is just a single indirect address in
	order for the value to be loaded and store in either GPR or VSX
	registers.  This affects the generated code, and it would cause
	this test to fail, when such an option is used.
