[LLVMdev] SelectionDAG constant folding leads to assertion failure
My experimental code calls DAG.getNode to construct a unary node with
a flag result. Unfortunately the argument turns out to be constant, so
lib/CodeGen/SelectionDAG/SelectionDAG.cpp:2332 calls VT.getSizeInBits
on the flag type, which isSimple(), so we call V.getSizeInBits at
ValueTypes.h:560 and fail at ValueTypes.h:240:
clang: .../include/llvm/CodeGen/ValueTypes.h:240: unsigned int
