tests/run-make/share-generics-export-again/rmake.rs

// When crates had different optimization levels, a bug caused
// incorrect symbol name generations. -Z share-generics could
// also fail to re-export upstream generics on multiple compile
// runs of the same dynamic library.

// This test repeatedly compiles an rlib and a dylib with these flags
// to check if this bug ever returns.

// See https://github.com/rust-lang/rust/pull/68277
// See https://github.com/rust-lang/rust/issues/64319
//@ ignore-cross-compile
