[Spice-devel] [PATCH 3/4] stat: use a better design for statistic functions
Frediano Ziglio

Wed Dec 2 03:43:09 PST 2015
make sure code compile with statistics enabled or disabled.
Dummy (empty) structures and functions are used instead of preprocessor.
Also fix a problem as stat_compress_init did not initialize clock
field.
