Andrea Di Biagio 5144469bb4 [DAGCombiner] Avoid introducing an illegal build_vector when folding a sign_extend. ... Make sure that we don't introduce illegal build_vector dag nodes when trying to fold a sign_extend of a build_vector. This fixes a regression introduced by r200234. Added test CodeGen/X86/fold-vector-sext-crash.ll to verify that llc no longer crashes with an assertion failure due to an illegal build_vector of type MVT::v4i64. Thanks to Ilia Filippov for spotting this regression and for providing a reproducible test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200313 91177308-0d34-0410-b5e6-96231b3b80d8		2014-01-28 12:53:56 +00:00
