[PATCH] D56435: We can improve the performance (generally) by memo-izing the action to map a debug location to its function summary.

[Wei Mi via Phabricator via llvm-commits]

wmi added a comment.

Seems the compile time saving is got mainly because there are multiple instructions sharing the same debug location, is my understanding correct?

If the understanding is correct, the memorized mapping seems only useful inside of each function, and is it better to clean the map at the end of runOnFunction instead of holding all the entries for the module?
