// This test case makes sure that two identical invocations of the compiler | ||
// (i.e. same code base, same compile-flags, same compiler-versions, etc.) | ||
// produce the same output. In the past, symbol names of monomorphized functions | ||
// were not deterministic (which we want to avoid). | ||
// | ||
// The test tries to exercise as many different paths into symbol name | ||
// generation as possible: | ||
// | ||
// - regular functions | ||
// - generic functions | ||
// - methods | ||
// - statics | ||
// - closures | ||
// - enum variant constructors | ||
// - tuple struct constructors | ||
// - drop glue | ||
// - FnOnce adapters | ||
// - Trait object shims | ||
