Here is the caller graph for this function:

bool stm::ByteLoggingUndoLogEntry::filter ( void **  lower, void **  upper  )

inline

The bytelog implementation of the filter operation support any sort of intersection possible.

Here is the call graph for this function:

bool stm::ByteLoggingUndoLogEntry::filterSlow ( void **  lower, void **  upper  )

private

We outline the slowpath filter. If this /ever/ happens it will be such a corner case that it just doesn't matter. Plus this is an abort path anyway.
