[PATCH] D124308: [MachineScheduler] exclude INLINEASM from schedule when it would increase register pressure

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

Do you have a feeling for how well this heuristic works for non-X86? I wonder if it would be better to be conservative and only have it in `X86InstrInfo::isSchedulingBoundary`, that way you could also hardcode some values instead of fiddeling with `getRegPressureLimit`.
