No, if you select -fprofile-update=atomic, then the updates shall be

This function could use a __gthread_mutex_t mutex for updates. This ends
up probably with quite a bad performance.

This avoids having to modify all the CC1_SPEC definitions in the targets.

move_sese_in_condition has most of that CFG manipulation (but
it performs sth different)
