--- Comment #3 from Jan Beich <[email protected]> ---
Clang 6.0.1 on 12.0 and devel/llvm70 before ports r490610 don't crash. Can
someone bisect, minimize and submit upstream for feedback?

$ sh nir_constant_expressions-9b094e.sh
Assertion failed: (!TLI.isOperationLegalOrCustom(N->getOpcode(), WideVecVT) &&
"Target supports vector op, but scalar requires expansion?"), function
WidenVectorResult, file
/usr/src/contrib/llvm/lib/CodeGen/SelectionDAG/LegalizeVectorTypes.cpp, line
2532.
Abort trap
