// This file defines the 'Statistic' class, which is designed to be an easy way
|
|
// to expose various metrics from passes. These statistics are printed at the
|
|
// end of a run (from llvm_shutdown), when the -stats command line option is
|
|
// passed 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;
|
|
//
|
|
// NOTE: Statistics *must* be declared as global variables.
