[PATCH] D30744: Improve machine schedulers for in-order processors

[Andrew Trick via Phabricator via llvm-commits]

I think what Matthias was getting at is that you can add a new ProcResource to model issue constraints. If you have a dual issue machine then any instruction that can't be grouped would simply consume both issue resources. Another option might be to use the begin/end group flags.

A SingleIssue flag seems like special casing a problem that needs a general solution.
