Use {Node}Gen#create instead of {Node}Factory#create to create new instances of nodes. +* Implemented a new generated code layout that reduces the code size. +* Changed all methods enclosed in a @TypeSystem must now be static. +* Changed all methods enclosed in generated type system classes are now static. +* Deprecated the type system constant used in the generated type system classes. +* Changed NodeFactory implementations are no longer generated by default. Use {Node}Gen#create instead of {Node}Factory#create to create new instances of nodes. * Added @GenerateNodeFactory to generate NodeFactory implementations for this node and its subclasses. - +* Deprecated @NodeAssumptions for removal in the next release. +* Deprecated experimental @Implies for removal in the next release. +* Added new package c.o.t.api.dsl.examples to the c.o.t.api.dsl project containing documented and debug-able Truffle-DSL use cases. +* Changed "typed execute methods" are no longer required for use as specialization return type or parameter. It is now sufficient to declare them in the @TypeSystem. +* Added @Cached annotation to express specialization local state. +* Added Specialization#limit to declare a limit expression for the maximum number of specialization instantiations. +* Changed syntax and semantics of Specialization#assumptions and Specialization#guards. They now use a Java like expression syntax. +* Changed guard expressions that do not bind any dynamic parameter are invoked just once per specialization instantiation. They are now asserted to be true on the fast path. +* Renamed @ImportGuards to @ImportStatic. ## Version 0.6 19-Dec-2014, [Repository Revision](http://hg.openjdk.java.net/graal/graal/shortlog/graal-0.6)

A cached parameter value is initialized once using the + * initializer expression at specialization instantiation. For each call of the specialization + * method the cached value is provided by using the annotated parameter from the method body. Cache + * initializers are potentially executed before guard expressions declared in + * {@link Specialization#guards()}. + * </p> + * <p> + * A typical specialization may define multiple dynamic and multiple cached parameters. Dynamic + * parameter values are typically provided by executing child nodes of the operation. Cached + * parameters are initialized and stored once per specialization instantiation. Cached parameters + * are always constant at compile time. You may verify this by invoking + * {@link CompilerAsserts#compilationConstant(Object)} on any cached parameter. For consistency + * between specialization declarations cached parameters must be declared last in a specialization + * method. + * </p> + * <p> + * The initializer expression of a cached parameter is defined using a subset of Java. This subset + * includes field/parameter accesses, function calls, type exact infix comparisons (==, !=, <, <=, + * >, >=) and integer literals. The return type of the initializer expression must be assignable to + * the parameter type. If the annotated parameter type is derived from {@link Node} then the + * {@link Node} instance is allowed to use the {@link Node#replace(Node)} method to replace itself. + * Bound elements without receivers are resolved using the following order: + * <ol> + * <li>Dynamic and cached parameters of the enclosing specialization.</li> + * <li>Fields defined using {@link NodeField} for the enclosing node.</li> + * <li>Public constructors of the type of the annotated parameter using the <code>new</code> keyword + * as method name.</li> + * <li>Public and static methods or fields of the type of the annotated parameter.</li> + * <li>Non-private, static or virtual methods or fields of enclosing node.</li> + * <li>Non-private, static or virtual methods or fields of super types of the enclosing node.</li> + * <li>Public and static methods or fields imported using {@link ImportStatic}.</li> + * </ol> + * + * The following examples explain the intended use of the {@link Cached} annotation.

The operand parameter is representing + * the dynamic value of the operand while the cachedOperand is initialized once at first execution + * of the specialization (specialization instantiation time). + * + * <pre> + * @Specialization + * void doCached(int operand, @Local("operand") int cachedOperand) { + * CompilerAsserts.compilationConstant(cachedOperand); + * ... + * } + * + * Example executions: + * execute(1) => doCached(1, 1) // new instantiation, localOperand is bound to 1 + * execute(0) => doCached(0, 1) + * execute(2) => doCached(2, 1) + * + * </pre> + * + * </li> + * <li> + * We extend the previous example by a guard for the cachedOperand value to be equal to the dynamic + * operand value. This specifies that the specialization is instantiated for each individual operand + * value that is provided. There are a lot of individual <code>int</code> values and for each + * individual <code>int</code> value a new specialization would get instantiated. The + * {@link Specialization#limit()} property defines a limit for the number of specializations that + * can get instantiated. If the specialization instantiation limit is reached then no further + * specializations are instantiated. Like for other specializations if there are no more + * specializations defined an {@link UnsupportedSpecializationException} is thrown.

In other words <code>doNormal</code> is more generic than <code>doCached</code> . The + * <code>doNormal</code> specialization uses <code>contains="doCached"</code> to specify + * that all instantiations of <code>doCached</code> get removed if <code>doNormal</code> is + * instantiated. Alternatively if the <code>contains</code> relation is omitted then all + * <code>doCached</code> instances remain but no new instances are created. + * + * <code> + * @Specialization(guards = "==(operand, cachedOperand)") + * void doCached(int operand, @Cached("operand") int cachedOperand) { + * CompilerAsserts.compilationConstant(cachedOperand); + * ... + * } + * + * @Specialization(contains = "doCached") + * void doNormal(int operand) {...} + * + * Example executions with contains = "doCached": + * execute(0) => doCached(0, 0) // new instantiation, cachedOperand is bound to 0 + * execute(1) => doCached(1, 1) // new instantiation, cachedOperand is bound to 1 + * execute(1) => doCached(1, 1) + * execute(2) => doCached(2, 2) // new instantiation, cachedOperand is bound to 2 + * execute(3) => doNormal(3) // new instantiation of doNormal due to limit overflow; doCached gets removed. + * execute(1) => doNormal(1) + * + * Example executions without contains = "doCached": + * execute(0) => doCached(0, 0) // new instantiation, cachedOperand is bound to 0 + * execute(1) => doCached(1, 1) // new instantiation, cachedOperand is bound to 1 + * execute(1) => doCached(1, 1) + * execute(2) => doCached(2, 2) // new instantiation, cachedOperand is bound to 2 + * execute(3) => doNormal(3) // new instantiation of doNormal due to limit overflow + * execute(1) => doCached(1, 1) + * + * </code> + * + * </li> + * <li> + * This next example shows how methods from the enclosing node can be used to initialize cached + * parameters.

Multiple + * specializations can be defined in a node representing an operation. A specialization defines + * which kind of input is expected using the method signature and the annotation attributes. The + * specialized semantics of the operation are defined using the body of the annotated Java method. A + * specialization method must be declared in a class that is derived from {@link Node} that + * references a {@link TypeSystem}. At least one specialization must be defined per operation. If no + * specialization is valid for the given set of input values then an + * {@link UnsupportedSpecializationException} is thrown instead of invoking any specialization + * method. + * </p> + * <p> + * A specialization must have at least as many parameters as there are {@link NodeChild} annotations + * declared for the enclosing operation node. These parameters are declared in the same order as the + * {@link NodeChild} annotations (linear execution order). We call such parameters dynamic input + * parameters. Every specialization that is declared within an operation must have an equal number + * of dynamic input parameters. + * </p> + * <p> + * The supported kind of input values for a specialization are declared using guards. A + * specialization may provide declarative specifications for four kinds of guards: + * <ul> + * <li><b>Type guards</b> optimistically assume the type of an input value. A value that matches the + * type is cast to its expected type automatically. Type guards are modeled using the parameter type + * of the specialization method. Types used for type guards must be defined in the + * {@link TypeSystem}. If the type of the parameter is {@link Object} then no type guard is used for + * the dynamic input parameter.</li> + * + * <li><b>Expression guards</b> optimistically assume the return value of a user-defined expression + * to be <code>true</code>. Expression guards are modeled using Java expressions that return a + * <code>boolean</code> value. If the guard expression returns <code>false</code>, the + * specialization is no longer applicable and the operation is re-specialized. Guard expressions are + * declared using the {@link #guards()} attribute.</li> + * + * <li><b>Event guards</b> trigger re-specialization in case an exception is thrown in the + * specialization body. The {@link #rewriteOn()} attribute can be used to declare a list of such + * exceptions. Guards of this kind are useful to avoid calculating a value twice when it is used in + * the guard and its specialization.</li> + * + * <li><b>Assumption guards</b> optimistically assume that the state of an {@link Assumption} + * remains <code>true</code>. Assumptions can be assigned to specializations using the + * {@link #assumptions()} attribute.</li> + * </ul> + * </p> + * <p> + * The enclosing {@link Node} of a specialization method must have at least one <code>public</code> + * and non-<code>final</code> execute method. An execute method is a method that starts with + * 'execute'. If all execute methods declare the first parameter type as {@link Frame}, + * {@link VirtualFrame} or {@link MaterializedFrame} then the same frame type can be used as + * optional first parameter of the specialization. This parameter does not count to the number of + * dynamic parameters. + * </p> + * <p> + * A specialization method may declare multiple parameters annotated with {@link Cached}. Cached + * parameters are initialized and stored once per specialization instantiation. For consistency + * between specialization declarations cached parameters must be declared last in a specialization + * method. + * </p> + * <p> + * If the operation is re-specialized or if it is executed for the first time then all declared + * specializations of the operation are tried in declaration order until the guards of the first + * specialization accepts the current input values. The new specialization is then added to the + * chain of current specialization instances which might consist of one (monomorph) or multiple + * instances (polymorph). If an assumption of an instantiated specialization is violated then + * re-specialization is triggered again. + * </p> + * <p> + * With guards in combination with cached parameters it is possible that multiple instances of the + * same specialization are created.
