--- Comment #6 from H. Peter Anvin <hpa at zytor dot com> --- Unfortunately that's not really possible given the way the way the level does runtime patching (which isn't going to change, sorry.) At the very least we would need a *lot* more compiler support to give LTO all the information that it needs; say a *very* minimum LTO would need to support ORC metadata.
