* ObjPtr<>-ify UnstartedRuntime, fix 2 stale reference uses.Vladimir Marko2018-05-231-74/+2
| | | | | | Test: Rely on TreeHugger. Bug: 31113334 Change-Id: I35f76c3e3b94dfca18dbe67aba065a1270f4e5ee
* ART: Update invoke-custom implementationOrion Hodson2018-03-081-0/+7
| | | | | | | | | | | | | | | | | | | Adds type checking for bootstrap arguments and support for variable arity bootstrap arguments. Adds tests for malformed bootstrap arguments, variable arity bootstrap arguments, and invocation arguments to passed to the CallSite's MethodHandle. Removes unnecessary wrapping when j.l.Error's are raised during BSM invocation. Removes BSM argument type checking from verifier. This is now performed during invocation.

* ART: Intrinsify polymorphic signature methodsOrion Hodson2017-11-011-8/+17
| | | | | | | | | | | | | | | Adds VarHandle accessor method to list of intrinsics. Adds code to interpreter to ensure intrinsics with polymorphic signatures are initialized. Rename most uses of InvokePolymorphic to InvokeMethodHandle (and similar changes) to be clear that the particular code path applies to MethodHandle instances rather than VarHandle.

* ART: Make method handle runtime code callable from compiler.Orion Hodson2017-01-061-48/+15
| | | | | | | | | | | Most of this change is moving the existing method handles code, but it also introduces a new header file, common_dex_operations.h, that has some operations taken from interpreter_common.{h,cc} that are also used by method handles (perform call, set field, get field).

* method_handles: Complete support for emulated stack frames.Narayan Kamath2016-10-281-12/+127
| | | | | | | | | | | | Most of this change is a refactor that templatizes the code that performs argument conversions. This allows us to copy arguments between two shadow frames, or an emulated stack frame and a shadow frame. Test: make test-art-host Bug: 30550796 Change-Id: I23e65735a2dbd28f3c7b7d1ccf9762e77e0cf1f1
* Interpreter: Add support for method handle transforms [Part 1].Narayan Kamath2016-10-261-9/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Method handle transformations are implemented in Java by subclasses of java.lang.invoke.Transformers.Transformer. Transformer extends MethodHandle and provides a transformer method defined like so: public static class TransformerImpl extends Transformer { @Override public void transform(EmulatedStackFrame emulatedStackFrame) throws Throwable { } } An EmulatedStackFrame is synthesized by the runtime based on the caller stack frame and arguments specified by the instruction. It will contain all input arguments to the method their associated types. It will also exactly match the method type specified by the target handle (i.e, argument coversions are performed by the runtime). The transformer method operates on supplied EmulatedStackFrame and other instance state to synthesize the transformation. In some cases, these transformations will end up calling other signature polymorphic methods. In those cases, the transformer can construct an EmulatedStackFrame and issue the invoke passing that through as the single input argument. For e.g, EmulatedStackFrame sf = EmulatedStackFrame.newInstance(); sf.pushArgument("foo", String.class); sf.pushIntArgument(42); // The callsite type for this polymorphic invoke is // (Ldalvik/system/EmulatedStackFrame)V; delegate.invoke(sf); The runtime will treat such polymorphic invokes specially and unmarshal this EmulatedStackFrame on to the callee stack frame based on the type and number of arguments contained in the EmulatedStackFrame and the declared type of the target method handle. In this change : Adds the basic plumbing for transformer invokes. In particular, the code for marshaling and unmarshaling emulated stack frames isn't implemented and will be added in a follow up method. This plumbing is sufficient to implement a test case of a method handle transform that doesn't need any input arguments, so is trivially implementable without proper EmulatedStackFrame support. bug: 30550796 Test: make test-art-host Change-Id: Iafa29accaef26d0a33f8b83713bed5d929df547e
* method_handles: Minor refactor of PerformArgumentConversions.Narayan Kamath2016-10-241-2/+9
| | | | | | | | | | | | Separate out a method that can perform a single argument conversion. Useful for Field setters and also for future use in transforming handles where the input source will not be a stack frame. Also remove unnecessary JValue* argument. bug: 30550796 Test: make test-art-host Change-Id: I75a63800839dbf1016a2c362169e138c83f34e4c
* interpreter: support for non-exact invokes.Narayan Kamath2016-10-141-0/+25
| | | | | | | | | | Performs primitive argument conversions as well as boxing and unboxing operations. Support for return value conversions will be added in a follow up change. Test: make test-art-host Change-Id: I2e3348ff64a5826e477f87c12a7d5c390eb3a653
* Basic implementation of invoke / invoke-polymorphic.Narayan Kamath2016-10-051-0/+51
Basic switch interpreter support for invoke-polymorphic. This change allows for virtual/interface and static invokes on method handles. Support for direct invokes (including constructors) and field getters and setters will be added in follow up changes. Bug: 30550796 Test: make test-art-host Change-Id: Ieb3a991d974060d930d56467908d5c7c11d0e38e
