[PATCH] D151227: RFC: LiveIntervalCalc: Always split separate components

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

The MIR is a standalone thing with rules on its own independent of the LiveIntervals. LiveIntervals is supposed to be a reflection of the MIR, it doesn't make sense to have restrictions on the MIR because of LiveIntervals. The implication there is some MIR which exists that's valid under -O0 but not with LiveIntervals suggests brokenness
