failing test case
This bitcode (which compiles fine with release 3.6):
target datalayout = "e-m:e-p:32:32-f64:32:64-f80:32-n8:16:32-S128"
target triple = "arm--linux-eabi"
define void @test() {
%1 = fptoui <16 x float> undef to <16 x i8>
store <16 x i8> %1, <16 x i8>* undef
ret void
}
compiled like this:
llc cast_f32x16_to_i8x16.ll -march=arm -mattr=+neon
produces this error:
llc: third_party/llvm/llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:6485:
