Bob, Justin, I've just committed a poor man's coverage implementation that works with asan. http://llvm.org/viewvc/llvm-project?rev=194701&view=rev http://llvm.org/viewvc/llvm-project?rev=194702&view=rev It provides only function-level boolean coverage (i.e. no counters, just "visited or not"), but is very fast and very simple (no extra sections to the binary file, etc)
