// This test case makes sure that two identical invocations of the compiler
2+
// (i.e. same code base, same compile-flags, same compiler-versions, etc.)
3+
// produce the same output. In the past, symbol names of monomorphized functions
4+
// were not deterministic (which we want to avoid).
5+
//
6+
// The test tries to exercise as many different paths into symbol name
7+
// generation as possible:
8+
//
9+
// - regular functions
10+
// - generic functions
11+
// - methods
12+
// - statics
13+
// - closures
14+
// - enum variant constructors
15+
// - tuple struct constructors
16+
// - drop glue
17+
// - FnOnce adapters
18+
// - Trait object shims
19+
// - Fn Pointer shims
