Hi Nikita,
This commit seems to cause a crash running llc -O0 on the following IR:
target triple = "thumbv7k-apple-darwin" define hidden void @foo(<2 x i64> *%ptr) { entry: %0 = load <2 x i64>, <2 x i64>* %ptr, align 8 %1 = call <2 x i64> @llvm.usub.sat.v2i64(<2 x i64> zeroinitializer, <2 x i64> %0) %2 = bitcast i64* undef to <2 x i64>* store <2 x i64> %1, <2 x i64>* %2, align 8 ret void }
; Function Attrs: nounwind readnone speculatable declare <2 x i64> @llvm.usub.sat.v2i64(<2 x i64>, <2 x i64>)
Could you take a look?
