//===-- StatisticReporter.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;
|
||
|
|
//
