| 1 | +// 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 |

| 23 | +// FIXME(Oneirical): two of these test blocks will apparently fail on windows |
| 24 | +// FIXME(Oneirical): try it on test-various |
