+// to expose various metrics from passes. These statistics are printed at the

//
// 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");
+// static Statistic NumInstsKilled("gcse", "Number of instructions killed");
//
// Later, in the code: ++NumInstsKilled;
//
+// NOTE: Statistics *must* be declared as global variables.
