Using hex format allows to better interpret IDs: the first digits represent the thread number, the last digits represent the ID within a thread The main change is in callback.h: PRIu64 -> PRIx64 The patch also guards RUN/CHECK lines in openmp/runtime/tests/ompt with clang-format on/off comments and clang-formats the directory. --------- Co-authored-by: Kaloyan Ignatov <kaloyan.ignatov@rwth-aachen.de>
