+// This file declares variants of the libFuzzer compare, division, switch and
+// gep hooks that accept an additional caller_pc argument that can be used to
+// pass a custom value that is recorded as the caller's instruction pointer
+// ("program counter"). This allows synthetic program counters obtained from
+// Java coverage information to be used with libFuzzer's value profile, with
+// which it records detailed information about the result of compares and
+// associates it with particular coverage locations.
+//
+// Note: Only the lower 9 bits of the caller_pc argument are used by libFuzzer.
