Deferred compilation of methods without backbranches based on simple invocation countes.
156.02 KB, patch
Details | Diff | Splinter Review
Methods with bounded execution time do not require on stack replacement for efficient adaptive compilation or recompilation. Dynamic compilation can be delayed until a method is determined to be hot, using, e.g., an invocation counter. One simple conservative approximation of bounded execution time is lack of back branches.
This is an old dirty patch, here for archiving purposes only. Relies on older versions background compilation patches (not factored out). At the time of testing, performance was flat.
