Currently AArch64FastISel crashes if it tries to extend an integer into an MVT::i128. This can happen by creating 128 bit integers like so: typedef unsigned int uint128_t __attribute__((mode(TI))); typedef int sint128_t __attribute__((mode(TI))); This patch makes EmitIntExt check for their presence and then falls back to SelectionDAG. Tests included. rdar://17516686 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212492 91177308-0d34-0410-b5e6-96231b3b80d8
