-// Regression test for #41697. Using dump-mir was triggering
-// artificial cycles: during type-checking, we had to get the MIR for
-// the constant expressions in `[u8; 2]`, which in turn would trigger
-// an attempt to get the def-path, which in turn would request the
-// types of the impl, which would trigger a cycle. We suppressed this
-// cycle now by forcing mir-dump to avoid asking for types of an impl.
