-// This file defines the 'Statistic' class, which is designed to be an easy way
-// to expose various success metrics from passes. These statistics are printed
-// at the end of a run, when the -stats command line option is enabled on the
-// command line.
-//
-// This is useful for reporting information like the number of instructions
-// simplified, optimized or removed by various transformations, like this:
-//
-// static Statistic<> NumInstsKilled("gcse", "Number of instructions killed");
-//
-// Later, in the code: ++NumInstsKilled;
