This project grew into an insanely powerful tool. It's called DynamoRIO and is still under active development and use today. It's one of the coolest technologies I've ever worked with.

It's used by the winafl fuzzer to provide basic block coverage for black box binaries.

Yes, I have poked around DynamoRIO a few times. It's now geared toward dynamically modifying binaries for various purposes from code coverage to fuzzing to performance and memory profiling.

There doesn't appear to currently be a turn-key solution similar to the original Dynamo. DynamoRIO could be used to put a small conditional tracing stub at the start of every basic block at application startup time, and then do some binary rewriting, similar to the original Dynamo, but it doesn't seem there are downloadable binaries that currently do this.

This dynamic optimization would be much easier and lower overhead (but less general) with cooperation from the compiler.
