//! Verify that we correctly handle fn pointer provenance in MIR optimizations.
//! By asking to inline `static_fnptr::bar`, we have two copies of `static_fnptr::foo`, one in the
//! auxiliary crate and one in the local crate CGU.
//! `baz` must only consider the versions from upstream crate, and not try to compare with the
//! address of the CGU-local copy.
//! Related issue: #123670
