-//===- BlockProfiling.cpp - Insert counters for block profiling -----------===//

-//
-// This pass instruments the specified program with counters for basic block or
-// function profiling.  This is the most basic form of profiling, which can tell
-// which blocks are hot, but cannot reliably detect hot paths through the CFG.
-// Block profiling counts the number of times each basic block executes, and
-// function profiling counts the number of times each function is called.
-//
-// Note that this implementation is very naive.  Control equivalent regions of
-// the CFG should not require duplicate counters, but we do put duplicate
-// counters in.
