Dear all, thank you, Claes, Vladimir, and Paul, for your reviews. See http://cr.openjdk.java.net/~mhaupt/8143211/webrev.01/ for the next round.
The difference to the previous version is, roughly, as follows. Rev 01 ... ... honours the possibility of there being more than one loop in a LambdaForm; InvokerBytecodeGenerator now has extra state summarising characteristics of the loops, while the concrete types are extracted from the LambdaForm during the actual compilation step. ... does away with the extra intrinsic data for loops. Instead, the LambdaFormEditor is used to create (and cache) an appropriate LambdaForm as a specialisation of a template. This was a very good suggestion from Vladimir (thanks!), and it makes the code much more tidy in my opinion. ... contains various small fixes that were suggested. Things I think should be expressed in other issues rather than being piggybacked on this one: * Removing IntrinsicMethodHandle. * Taking care of Transform cache cleanup.
