8044102: Ensure bechmark exclude list for Octane benchmarks is in only one place, project.properties, and fix benchmark harness Reviewed-by: attila, sundar

8044012: Integrate the latest best known performance flags int ant octane jobs, and make sure that it's easy to compare 'ant octane-nashorn' and 'ant octane-v8' at the push of a button. (or rather; the entry of a command line) Reviewed-by: jlaskey, sundar

8043632: Parallelize class installation and various script fixes. Reviewed-by: sundar, attila

8043611: Move timing dependent benchmark for apply2call specialization to currently_failing. It is dependent that nothing takes machine time when doing the two runs, causing spurious assertions. Suggest running octane.raytrace manually instead to verify that this works, or incorporating it in the nightly test suite Reviewed-by: sundar, attila

8043633: In order to remove global state outside of contexts, make sure Timing class is an instance and not a static global collection of data. Move into Context. Move -Dnashorn.timing to an official logging option. Reviewed-by: sundar, attila

8033105: Make sure Nashorn test harness can run zlib benchmark Reviewed-by: attila, hannesw

8040655: When processing a RewriteException debug object, the return value has already been reset to null. We need to catch this value before that. Reviewed-by: attila, lagergren Contributed-by: matherey.nunez@oracle.com

8040102: Remove all references to Unsafe and definition of anonymous clases from the code Summary: As the catch combinator optimization is now part of java.lang.invoke we don't need to put our own in the boot class path in any configuration anymore. Furthermore, with the completion of the array performance subtask of optimistic typing, we can remove the experimental (commented out) Unsafe accessors in the ArrayData classes Reviewed-by: attila, jlaskey

8040089: Apply to call transform was incomplete. Now passes all tests and performance is back Reviewed-by: hannesw, attila, sundar, jlaskey

8038799: Guard and unbox boxed primitives types on setting them in Properties to avoid megamorphisism Reviewed-by: attila, jlaskey

8027043: Turn global accesses into MethodHandle.constant, with one chance of reassignment, e.g. x = value occuring once in the global scope is ok, twice is not. Reviewed-by: attila, sundar, jlaskey

8038416: Access to undefined scoped variables deoptimized too much Reviewed-by: jlaskey, lagergren

8038406: Testability: as a first step of moving loggers away from the process global space, the Debug object now supports logging POJOs from log entries as an event queue, which can be introspected from test scripts. This is way better than screen scraping brittle and subject-to-change log output. Reviewed-by: attila, hannesw, sundar

8033334: Make sure that scope depth information is maintained in the RecompilableScriptFunctionDatas, to avoid unnecessary slow proto linkage when doing on demand compilation Summary: Compute RecompiledScriptFunctionDatas eagerly, annotate them with scope depth information and use them in recompilations. Reviewed-by: attila, hannesw, jlaskey

8037086: Check that deoptimizing recompilations are correct Reviewed-by: attila, lagergren

8036986: Test should check that correctly type is returned running with optimistic. If optimistic assumption was wrong we should get the right one. Summary: This uses the inspection framework for generated code to ensure optimisim. Reviewed-by: attila, lagergren Contributed-by: matherey.nunez@oracle.com

8037177: -Dnashorn.optimistic should be enabled by default, meaning that it has to be explicitly set to false to run with the jdk 8 style conservative types Summary: This will be the new default setting, so the explicit flag should be removed, and instead reverse checked for explicitly DISABLED optimistic types. In the future, we might remove the flag altogether. Reviewed-by: attila, hannesw

8036127: Prototype filter needs to be applied to getter guard as well, not just getter Summary: This manifests itself as a bug in optimistic types, as inner functions may access properties of the wrong type, but it is also a bug in tip. Without optimistic types, we have been unable to find a reproducer due to more similar PropertyMaps Reviewed-by: attila, jlaskey, sundar
