Function common_inputs_stamp

pub(crate) fn common_inputs_stamp(config: &Config) -> Stamp

Returns the most recent last-modified timestamp from among the input files that are considered relevant to all tests (e.g. the compiler, std, and compiletest itself).

(Some of these inputs aren’t actually relevant to all tests, but they are common to some subset of tests, and are hopefully unlikely to be modified while working on other tests.)
