Hal Finkel 1523211990 Add an optional ability to expand larger BUILD_VECTORs with shuffles ... This adds the ability to expand large (meaning with more than two unique defined values) BUILD_VECTOR nodes in terms of SCALAR_TO_VECTOR and (legal) vector shuffles. There is now no limit of the size we are capable of expanding this way, although we don't currently do this for vectors with many unique values because of the default implementation of TLI's shouldExpandBuildVectorWithShuffles function. There is currently no functional change to any existing targets because the new capabilities are not used unless some target overrides the TLI shouldExpandBuildVectorWithShuffles function. As a result, I've not included a test case for the new functionality in this commit, but regression tests will (at least) be added soon when I commit support for the PPC QPX vector instruction set. The benefit of committing this now is that it makes the shouldExpandBuildVectorWithShuffles callback, which had to be added for other reasons regardless, fully functional. I suspect that other targets will also benefit from tuning the heuristic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205243 91177308-0d34-0410-b5e6-96231b3b80d8		2014-03-31 19:42:55 +00:00
