Chandler Carruth f2d7693fbb Begin teaching the X86 target how to efficiently codegen patterns that ... use the zero-undefined variants of CTTZ and CTLZ. These are just simple patterns for now, there is more to be done to make real world code using these constructs be optimized and codegen'ed properly on X86. The existing tests are spiffed up to check that we no longer generate unnecessary cmov instructions, and that we generate the very important 'xor' to transform bsr which counts the index of the most significant one bit to the number of leading (most significant) zero bits. Also they now check that when the variant with defined zero result is used, the cmov is still produced. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146974 91177308-0d34-0410-b5e6-96231b3b80d8		2011-12-20 11:19:37 +00:00
