// 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
