[Valgrind-users] Limiting helgrind to finding only write-write conflicts

[Phil L. <plo...@sa...>]

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.
