<pre>Test case test.c:
------------------------------------------------------------------
#include "arm_neon.h"
uint64_t dotests_type_legalizer(int64x1_t in0) {
return vget_lane_u64(vorn_u64(vcgez_s64(in0),
in0),
0);
}
------------------------------------------------------------------
To RUN:
clang -O3 --target=arm64-linux-gnu -c test.c
The Error information is as following:
/lib/CodeGen/SelectionDAG/LegalizeTypes.h:506: llvm::SDValue
llvm::DAGTypeLegalizer::GetScalarizedVector(llvm::SDValue): Assertion
`ScalarizedOp.getNode() && "Operand wasn't scalarized?"' failed.
AArch64 backend once also had such assertion failure. It was fixed in the
backend <a href="http://llvm.org/viewvc/llvm-project?view=revision&revision=201381">http://llvm.org/viewvc/llvm-project?view=revision&revision=201381</a>.</pre>
