+<h2>Abstract:</h2>
+<blockquote>
+<p>
+Profiling monitors a programâs execution flow via the insertion of
+counters at key points in the program. Profiling information can then
+be used by a compilerâs optimization passes to increase the
+performance of frequently executed sections of code. This document
+describes the implementation of edge profiling, path profiling and a
+method with which to combine profiles in the Low Level Virtual Machine
+(LLVM) compiler infrastructure.
