[SPARC] Emit compareAndSwap for AtomicInteger and AtomicLong, Removing o7 register from usable ones, as this register is always overwritten, when using Call or JumpAndLink instructions in SPARC, even callee does not overwrite explicitly, implicit exception is defined when doing integer division, parameter constraint narrowed to only register on Unary2Op, Fix SPARCTestOp, as it did a compare instead of an and with condition codes

# 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).
