Fix that by adding a cast to the shift expander. This came up with vector shifts on sse-less X86 CPUs. <2 x i64> = shl <2 x i64> <2 x i64> -> i64,i64 = shl i64 i64; shl i64 i64 -> i32,i32,i32,i32 = shl_parts i32 i32 i64; shl_parts i32 i32 i64 Now we cast the last two i64s to the right type. Fixes the crash in PR14668. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173615 91177308-0d34-0410-b5e6-96231b3b80d8
