Arnold Schwaighofer b40f14eb89 LoopVectorizer: Truncate i64 trip counts of i32 phis if necessary ... In signed arithmetic we could end up with an i64 trip count for an i32 phi. Because it is signed arithmetic we know that this is only defined if the i32 does not wrap. It is therefore safe to truncate the i64 trip count to a i32 value. Fixes PR18049. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195787 91177308-0d34-0410-b5e6-96231b3b80d8		2013-11-26 22:11:23 +00:00
