-//===-- Statistic.cpp - Easy way to expose stats information --------------===//
-//
-// This file implements 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<> NumInstEliminated("GCSE - Number of instructions killed");
-//
-// Later, in the code: ++NumInstEliminated;
-//
