// Issue 61188 pointed out a case where we hit an ICE during code gen:
|
|
// the compiler assumed that `PartialEq` was always implemented on any
|
|
// use of a `const` item in a pattern context, but the pre-existing
|
|
// structural-match checking was too shallow
|
|
// (see rust-lang/rust#62307), and so we hit cases where we were
|
|
// trying to dispatch to `PartialEq` on types that did not implement
|
|
// that trait.
