I think we can make it work, though. The important thing is that the ByteCodeParser needs to use the firstFreeRegister operand to decode how to lay out the call as if it was a normal call, and then to emit a sled of SetLocal's representing the arguments - again, as if this had been a normal call. Those SetLocals would be ImmediateSet. Anyway, it'l be super amazing. 971680 2 222130 fpizlo 2014-01-24 11:43:39 -0800 Created attachment 222130 getting there It still has OSR exit issues but it's starting to look like something. 971715 3
