[PATCH] D149800: [WIP][PGO] Add ability to mark cold functions as optsize/minsize/optnone

[David Li via Phabricator via cfe-commits]

davidxl added a comment.

This patch uses a cleaner method than the previous effort. There is some differences:

1. yamauchi's patch works for both iFDO and autoFDO, while this patch limits to iFDO
2. yamauchi's patch also handles size optimization (IIRC) at granularity smaller than function

Longer term, the previous functionality should fold into the new framework.
