You can get statistics on the cache (its size, number of hits,

misses, etc.) by running +make ccache-stats+.



The make target +ccache-options+ and the +CCACHE_OPTIONS+ variable

provide more generic access to the ccache. For example



-----------------

# set cache limit size

make CCACHE_OPTIONS="--max-size=5G" ccache-options



# zero statistics counters

make CCACHE_OPTIONS="--zero-stats" ccache-options
