For a different approach to this issue: if helgrind can't reliably detect
atomic operations, as discussed before, and if VALGRIND_HG_ENABLE_CHECKING is
broken (see my previous email in this thread), then a simple solution is to
add suppressions.
{
QBasicAtomicPointer_load
Helgrind:Race
fun:_ZNK19QBasicAtomicPointer*loadAcquireEv
}
has cut down the noise considerably in my tests.
Plus a few similar ones, like QBasicAtomicInt.
Historically we had Qt-related suppressions in a suppression file shipped with
KDE, but there are many more Qt users than the KDE developers. Would it be OK
to ship a qt5.supp file within valgrind, and load it unconditionnally, like
xfree-4.supp is currently handled?
