[PATCH] D21675: New ODR checker for modules

[Richard Trieu via Phabricator via cfe-commits]

rtrieu updated this revision to Diff 86142.
rtrieu added a comment.

Changes made to the ODR hash algorithm:

Separated Decl and Type pointers into their own DenseMap's.
Removed the queue of pointers to process at the end.  Instead, process pointers at first use.
Save Boolean values and add them together at the end to reduce bits wasted.  Shrinks data from bools 32x.

With these changes, the overhead is now 1-1.5%
