| # A full build of llvm, clang, lld, and lldb takes about 250MB | |
| # of ccache space. There's not much reason to have more than this, | |
| # because we usually won't need to save cache entries from older | |
| # builds. Also, there is an overall 10GB cache limit, and each | |
| # run creates a new cache entry so we want to ensure that we have | |
| # enough cache space for all the tests to run at once and still | |
