The issue is when instrumented objects interact with gcc object,, for instance running instrumented binaries on usual distros like Ubuntu. I haven't tested on a all-clang/all-thumb system, but from my understanding is clang thumb use the FP similar no arm mode (differerent than gcc), so it should work.
