Use [accepts-invalid] and [rejects-valid] instead
llvm:codegen
Extended Description
it looks like switch lowering is creating an invalid phi node. To reproduce, use:
$ llvm-as < bugpoint-reduced-simplified.ll | llc -fast
This seems to only occur with -fast. Maybe switch lowering depends on critical edges being split or
something? -fast is used for -O0 compiles.
