 Add a change in pressure to the pressure diff of a given instruction. More...
 

Detailed Description

List of PressureChanges in order of increasing, unique PSetID.

Use a small fixed number, because we can fit more PressureChanges in an empty SmallVector than ever need to be tracked per register class. If more PSets are affected, then we only track the most constrained.
