# 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.

# - MPFR is required by some of the mathlib tests.
