[PATCH] D77849: [calcspillweights] mark LiveIntervals from INLINEASM_BR defs as not spillable

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

Using LiveIntervals in any way is not an option to solve this. They are not available in all fast regalloc and other allocators. The constraints need to be expressed with copies that are terminators, and splitting blocks when necessary
