Can you tell us if you're continuing to use the same approach as described in one of the LLVM meetings, i.e. instrument at the clang AST level? Also, do you generate GCOV files, some yaml, or is this a separate format? And finally in the meeting you had given how you assign counters to the blocks, an algorithm to minimize the number of insertions. Is that algorithm a well-known one or a
