# GraalVM Changelog ## `tip` ### Graal * Made initialization of Graal runtime lazy in hosted mode. * Added supported for new 'jrelibrary' dependency type in mx/projects. * Java projects with compliance level higher than the JDKs specified by JAVA_HOME and EXTRA_JAVA_HOMES are ignored once mx/projects has been processed. * ResolvedJavaType.resolveMethod now takes a context type used to perform access checks. It now works correctly regarding default methods. * Removed Java based compilation queue (CompilationQueue.java). * Enabled use of separate class loader (via -XX:+UseGraalClassLoader) for classes loaded from graal.jar to hide them from application classes. ### Truffle * New flag -G:+TraceTruffleCompilationCallTree to print the tree of inlined calls before compilation. * `truffle.jar`: strip out build-time only dependency into a seperated JAR file (`truffle-dsl-processor.jar`) * New flag -G:+TraceTruffleCompilationAST to print the AST before compilation. * New experimental TypedObject interface added. * Renamed flag -G:+TruffleSplittingEnabled to -G:+TruffleSplitting * New flag -G:+TruffleSplittingNew to enable the experimental splitting mode based on function arguments. * New flag -G:+TruffleSplittingTypedInstanceStamps to enable splitting for TypedObject instances. * New flag -G:+TruffleSplittingClassInstanceStamps to enable splitting for Java object instances except TypedObject. * New flag -G:TruffleSplittingStartCallCount=3 which sets the number of minimal calls until splitting is performed. * New flag -G:-TruffleSplittingAggressive if enabled splits every function call. * ... ## Version 0.3 9-May-2014, [Repository Revision](http://hg.openjdk.java.net/graal/graal/rev/graal-0.3) ### Graal * Explicit support for oop compression/uncompression in high level graph. * LIRGenerator refactoring. * Explicit types for inputs (InputType enum). * Added graal.version system property to Graal enabled VM builds. * Transitioned to JDK 8 as minimum JDK level for Graal. * Added support for stack introspection. * New MatchRule facility to convert multiple HIR nodes into specialized LIR ### Truffle * The method `CallTarget#call` takes now a variable number of Object arguments. * Support for collecting stack traces and for accessing the current frame in slow paths (see `TruffleRuntime#getStackTrace`). * Renamed `CallNode` to `DirectCallNode`. * Renamed `TruffleRuntime#createCallNode` to `TruffleRuntime#createDirectCallNode`. * Added `IndirectCallNode` for calls with a changing `CallTarget`. * Added `TruffleRuntime#createIndirectCallNode` to create an `IndirectCallNode`. * `DirectCallNode#inline` was renamed to `DirectCallNode#forceInlining()`. * Removed deprecated `Node#adoptChild`. ## Version 0.2 25-Mar-2014, [Repository Revision](http://hg.openjdk.java.net/graal/graal/rev/graal-0.2) ### Graal * Use HotSpot stubs for certain array copy operations. * New methods for querying memory usage of individual objects and object graphs in Graal API (`MetaAccessProvider#getMemorySize`, `MetaUtil#getMemorySizeRecursive`). * Added tiered configuration (C1 + Graal). * Initial security model for Graal [GRAAL-22](https://bugs.openjdk.java.net/browse/GRAAL-22). * New (tested) invariant that equality comparisons for `JavaType`/`JavaMethod`/`JavaField` values use `.equals()` instead of `==`. * Made graph caching compilation-local. * Added AllocSpy tool for analyzing allocation in Graal using the [Java Allocation Instrumenter](https://code.google.com/p/java-allocation-instrumenter/). * Initial support for memory arithmetic operations on x86. * Expanded Debug logging/dumping API to avoid allocation when this Debug facilities are not enabled. ### Truffle * New API `TruffleRuntime#createCallNode` to create call nodes and to give the runtime system control over its implementation. * New API `RootNode#getCachedCallNodes` to get a weak set of `CallNode`s that have registered to call the `RootNode`. * New API to split the AST of a call-site context sensitively. `CallNode#split`, `CallNode#isSplittable`, `CallNode#getSplitCallTarget`, `CallNode#getCurrentCallTarget`, `RootNode#isSplittable`, `RootNode#split`. * New API to inline a call-site into the call-graph. `CallNode#isInlinable`, `CallNode#inline`, `CallNode#isInlined`. * New API for the runtime environment to register `CallTarget`s as caller to the `RootNode`. `CallNode#registerCallTarget`. * Improved API for counting nodes in Truffle ASTs. `NodeUtil#countNodes` can be used with a `NodeFilter`. * New API to declare the cost of a Node for use in runtime environment specific heuristics. See `NodeCost`, `Node#getCost` and `NodeInfo#cost`. * Removed old API for `NodeInfo#Kind` and `NodeInfo#kind`. As a replacement the new `NodeCost` API can be used. * Changed `Node#replace` reason parameter type to `CharSequence` (to enable lazy string building) * Deprecated `Node#adoptChild` and `Node#adoptChildren`, no longer needed in node constructor * New `Node#insert` method for inserting new nodes into the tree (formerly `adoptChild`) * New `Node#adoptChildren` helper method that adopts all (direct and indirect) children of a node * New API `Node#atomic` for atomic tree operations * Made `Node#replace` thread-safe ## Version 0.1 5-Feb-2014, [Repository Revision](http://hg.openjdk.java.net/graal/graal/rev/graal-0.1) ### Graal * Initial version of a dynamic Java compiler written in Java. * Support for multiple co-existing GPU backends ([GRAAL-1](https://bugs.openjdk.java.net/browse/GRAAL-1)). * Fixed a compiler bug when running RuneScape ([GRAAL-7](https://bugs.openjdk.java.net/browse/GRAAL-7)). * Bug fixes ([GRAAL-4](https://bugs.openjdk.java.net/browse/GRAAL-4), [GRAAL-5](https://bugs.openjdk.java.net/browse/GRAAL-5)). ### Truffle * Initial version of a multi-language framework on top of Graal. * Update of the [Truffle Inlining API](http://mail.openjdk.java.net/pipermail/graal-dev/2014-January/001516.html).
