	Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures. No code review, as discussed with Hal Finkel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@277624 91177308-0d34-0410-b5e6-96231b3b80d8
2015-02-05	[PowerPC] Implement the vclz instructions for PWR8	Bill Schmidt
	Patch by Kit Barton. Add the vector count leading zeros instruction for byte, halfword, word, and doubleword sizes. This is a fairly straightforward addition after the changes made for vpopcnt: 1. Add the correct definitions for the various instructions in PPCInstrAltivec.td 2. Make the CTLZ operation legal on vector types when using P8Altivec in PPCISelLowering.cpp Test Plan Created new test case in test/CodeGen/PowerPC/vec_clz.ll to check the instructions are being generated when the CTLZ operation is used in LLVM. Check the encoding and decoding in test/MC/PowerPC/ppc_encoding_vmx.s and test/Disassembler/PowerPC/ppc_encoding_vmx.txt respectively. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@228301 91177308-0d34-0410-b5e6-96231b3b80d8
