patterns generated by clang for transpose of a matrix in generic vectors. This is made of two parts: 1) Propagating vector extracts of hi/lo half into their users 2) Recognizing an insertion of even elements followed by the odd elements as an unpack. Testcase to come, but this shrinks the # of shuffle instructions generated on x86 from ~40 to the minimal 8. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110734 91177308-0d34-0410-b5e6-96231b3b80d8 |
