8037967: Broke the build, by commiting without saving the last review comment Reviewed-by: jlaskey, hannesw

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

8035836: Array performance improvements Summary: Implement typed arrays with native byte buffers and do fast linking for all continuous arrays Reviewed-by: attila, jlaskey, sundar, hannesw
