Ccache – a fast C/C++ compiler cache

ccache uses cryptographic hashing of file contents, in addition to matching compiler arguments, so you can be sure that the code matches.

It uses a cryptographic hash of the _inputs_ to the compiler, but there is no way to verify that the cached artifact matches the _output_ of the compiler without actually compiling it yourself.
