-|* 
-|* This file implements the call back routines for the gcov profiling
-|* instrumentation pass. Link against this library when running code through
-|* the -insert-gcov-profiling LLVM pass.
-|*
-|* We emit files in a corrupt version of GCOV's "gcda" file format. These files
-|* are only close enough that LCOV will happily parse them. Anything that lcov
-|* ignores is missing.
-|*
-|* TODO: gcov is multi-process safe by having each exit open the existing file
-|* and append to it. We'd like to achieve that and be thread-safe too.
