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

8043605: Enable history for empty property maps Reviewed-by: jlaskey, sundar

8043608: Make equality tests inline better Reviewed-by: lagergren, sundar

8043504: Octane test harness was missing argument to print_always at one callsite, causing erroneous logging Reviewed-by: sundar, attila

8043431: Fix yet another corner case of JDK-8041995 Reviewed-by: hannesw, lagergren

8034206: Make parts of code pipeline reusable in order to facilitate faster warmup and faster lazy compilation. Reviewed-by: hannesw, attila

8043235: Type-based optimizations interfere with continuation methods Reviewed-by: jlaskey, lagergren

8043133: Fix corner cases of JDK-8041995 Reviewed-by: hannesw, lagergren

8044154: Nashorn : all tests failed with java.security.AccessControlException Reviewed-by: attila, sundar

8043137: Collapse long sequences of NOP in Nashorn bytecode output Reviewed-by: jlaskey, lagergren

8043004: Reduce variability at JavaAdapter call sites Reviewed-by: lagergren, sundar

8043003: Use strongly referenced generic invokers Reviewed-by: lagergren, sundar

8043002: Improve performance of Nashorn equality operators Reviewed-by: lagergren, sundar

8042118: Separate types from symbols Reviewed-by: hannesw, lagergren

8037572: Add more test cases to check static types Reviewed-by: attila, lagergren

8041625: AccessorProperty currentType must only by Object.class when non-primitive, and scoping followup problem for lazily generated with bodies Reviewed-by: jlaskey, attila

8038398: OptimisticRecompilationTest fails on staging repo nashorn/jdk9/nashorn due to test framework Reviewed-by: attila, lagergren

8041995: Problems when loading tree expressions with several optimistic program points when optimistically initializing ObjectNodes Reviewed-by: jlaskey, attila

8041905: Fix apply2call bug that prevented avatar.js unit tests from running correctly Reviewed-by: attila, hannesw

8041434: Add synchronization to the common global constants structure Reviewed-by: attila, hannesw

8038426: Move all loggers from process wide scope into Global scope Reviewed-by: attila, hannesw

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

Merge

8039746: Transform applies to calls wherever possible, for ScriptFunctions and JSObjects. Reviewed-by: hannesw, attila, sundar, jlaskey

8040024: BranchOptimizer produces bad code for NaN FP comparison Reviewed-by: jlaskey, lagergren

8039044: Expand undefined intrinsics for all commutative combinators of scrict undefined checks Reviewed-by: jlaskey, hannesw

8038945: Simplify strict undefined checks Reviewed-by: jlaskey, hannesw

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

8038396: fix for the compiler expression evaluator to be more inquisitive about types Reviewed-by: hannesw, lagergren

8037534: Use scope types to determine optimistic types Reviewed-by: hannesw, lagergren
