I don't see any command line options which limit helgrind to ignoring
read/write or write/read conflicts and only displaying write/write conflicts.
Would that be hard to add?
We have situations where we think only 1 thread updates some counter, and
periodically, another thread reads the value for display. If there's a
conflict, we don't really care whether the display shows the before or the
after value. However, we are interested in knowing if some other code path
tries to update the value i.e. we care about write/write conflicts.
