# GraalVM Changelog ## `tip` ### 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 * ... ### Truffle * Support for collecting stack traces and for accessing the current frame in slow paths * 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(). * ... ## 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#adoptChild`, 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).
