// This test case makes sure that the compiler does not try to re-use anything
|
||
|
|
// from the incremental compilation cache if the cache was produced by a
|
||
|
|
// different compiler version. This is tested by artificially forcing the
|
||
|
|
// emission of a different compiler version in the header of rpass1 artifacts,
|
||
|
|
// and then making sure that the only object file of the test program gets
|
||
|
|
// re-translated although the program stays unchanged.

// The `l33t haxx0r` Rust compiler is known to produce incr. comp. artifacts
