I wonder if anyone considered adding ccache support for
buildworld/release targets. ccache is a tool, which wraps around gcc,
allowing to cache object files generated by the compiler to greatly
speed-up compilation of the same code over and over
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.
It can benefit both individual developers (less burden to test changes
via full buildworld), and tinderboxes.
Another interesting use is for package building cluster - it should be
possible to set-up NFS folder shared among all nodes to hold cached
objects for all ports in the tree to reduce turnaround time by the order
