| # Libc's build is relatively small comparing with other components of LLVM. |
| # A fresh fullbuild takes about 190MiB of uncompressed disk space, which can |
| # be compressed into ~40MiB. Limiting the cache size to 1G should be enough. |
| # Prefer sccache as it is more modern. |
| # Do not use direct GHAC access even though it is supported by sccache. GHAC rejects |
| # frequent small object writes. |
