Regression reported by AWFY: misc-basic-arguments: from 38ms to 40.3ms The regression appears for JM only. The regression appeared between changesets dcf78e64e1bd and 43e09a8466c2, which only includes Bug 804636 part 3 among the changes made to the JS engine.
Yeah that was kind of expected, it removed the loop test analysis from JM+TI. I'm tempted to close this as WONTFIX, the new baseline compiler will also not have these optimizations. JM+Ion is the configuration we ship and that's what we should not regress imo...
