ccache is a compiler cache. It acts as a caching pre-processor to C/C++ compilers, using the -E compiler switch and a hash to detect when a compilation can be satisfied from cache. This often results in a 5 to 10 times speedup in common compilations. PR: 234971 Approved by: bdrewery Author: Oleg Sidorkin <osidorkin@gmail.com>
