[PATCH v4 4/4] merge-ort: miscellaneous touch-ups

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Elijah Newren <newren@xxxxxxxxx>

Add some notes in the code about invariants with match_mask when adding
pairs.  Also add a comment that seems to have been left out in my work
of pushing these changes upstream.
