This is expected and within a reasonable amount for the APIs in question. We took a change to the LSRA heuristics which gave an overall size win, but which resulted in some size regressions in other APIs. As Jakob pointed out, a lot of this is just due to slightly different register selection resulting in different spillage and there's not much that can be done without changing how LSRA works more deeply.

The regression in Burgers is pretty sizeable, did you look at that one in any detail?
