// 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
// 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");
+// static Statistic<> NumInstsKilled("gcse", "Number of instructions killed");
//
-// Later, in the code: ++NumInstEliminated;
+// Later, in the code: ++NumInstsKilled;
//

-// DebugFlag - This boolean is set to true if the '-debug' command line option
-// is specified. This should probably not be referenced directly, instead, use
-// the DEBUG macro below.
-//
-extern bool DebugFlag;
-
-// DEBUG macro - This macro should be used by passes to emit debug information.
-// In the '-debug' option is specified on the commandline, and if this is a
-// debug build, then the code specified as the option to the macro will be
-// executed. Otherwise it will not be. Example:
-//
-// DEBUG(cerr << "Bitset contains: " << Bitset << "\n");
-//
-#ifdef NDEBUG
-#define DEBUG(X)
-#else
-#define DEBUG(X) \
- do { if (DebugFlag) { X; } } while (0)
