| * SI-6710 / PR 5072 follow-up: fix Unit.box / Unit.unboxLukas Rytz2016-04-201-2/+2
| | | | | | | | | | | | | | The backend replaces .box / .unbox methods by corresponding invocations to BoxesRunTime, but not for Unit. This commit restores the body of `Unit.box` and `Unit.unbox`.

| | | | | | | | Because it was its only call site.
* | Inline ScalaRunTime.arrayElementClass at call sites.Sébastien Doeraene2016-04-135-23/+10
| | | | | | | | | | | | | | | | | | | | This method was awful. Not only it was using run-time type tests to essentially encode compile-time overloading. But it also did 2 slightly different things for the Class case and ClassTag case. All in all, it is much more readable to inline the appropriate implementation at every call site.
* | Move ScalaRunTime.isAnyVal to reify.phases.Reify.Sébastien Doeraene2016-04-131-5/+0
| | | | | | | | Because that is the only call site of that method.
* | Hide ScalaRunTime.isTuple inside stringOf.Sébastien Doeraene2016-04-131-2/+3
| | | | | | | | Because it is otherwise unused.
* | Remove dead-code runtime hash() methods.Sébastien Doeraene2016-04-132-44/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | ScalaRunTime had a bunch of overloads of the `hash()` method, but only the `Any` version is ever used by the codegen. Worse, their implementation was not in sync with the actual implementations in BoxesRunTime, called by the `Any` version. For example, hash(0x80000000L) != hash(0x80000000L: Any) This commit simply removes all of this dead code. Similarly, we remove BoxesRunTime.hashFromObject(), which was never called either.
* | Inline ArrayRuntime methods in ScalaRunTime.array_clone().Sébastien Doeraene2016-04-132-35/+9
|/ | | | | | | | | | | | | | Support for Array[T].clone() was introduced in 36ef60e68c03bc1c7fd2e910ae7d70d4ec32d3bf. At the time, all calls to array.clone() were redirected to ScalaRunTime.array_clone(), which meant that array_clone() itself could not be implemented in terms of `x.clone()`. A Java binding was necessary. Now, the rewriting to `array_clone()` is only done for unbounded generic arrays. Since all the calls within `array_clone()` are monomorphic arrays, the rewriting is not applied, and the Java binding is unnecessary.

* Generate AnyVal source stubs from sbtStefan Zeiger2016-04-069-18/+18
| | | | | | | | | | | | The sbt command `generateSources` now generates both the AnyVal sources and the tuple/function sources (previously done by `genprod`). Source generation is part of the sbt build, the `scala.tools.cmd.gen` package is removed from `scala-compiler`. This simplifies bootstrapping. Generated sources are still in the same location and checked into git. The shell scripts `tools/codegen` and `tools/codegen-anyvals` are also removed. The ant build and the build scripts do not call these. Regenerating sources is a manual step at the moment.

* SI-6710 Clarify stub methods in primitive value classesLukas Rytz2016-04-019-27/+36
| | | | | | | | | - Replaces the implementations of box/unbox in AnyVal companions by `???`, the methods are only stubs, and the impls did not correspond to the actual behavior. The doc comment already points to the actual implementation in BoxesRunTime. - Replaces the body of `getClass` from `null` to `???` and clarifies in a comment why the overrides exist.

Notice how `apply$mcB$sp` is looking pretty SAMmy: ``` @FunctionalInterface public interface JFunction0$mcB$sp extends JFunction0 { @Override public byte apply$mcB$sp(); @Override default public Object apply() { return BoxesRunTime.boxToByte(this.apply$mcB$sp()); } } ``` Contrast this with our specialized standard FunctionN: ``` public interface Function0<R> { public R apply(); default public byte apply$mcB$sp() { return BoxesRunTime.unboxToByte(this.apply()); } } public interface Function0$mcB$sp extends Function0<Object> { } ``` The single abstract method in `Function0$mcB$sp` is `apply`, and the method that would let us avoid boxing, if it were abstract, is `apply$mcB$sp`... TODO (after M4): - do same for specialized functions (issues with boxing?) - remove scala/runtime/java8/JFunction* (need new STARR?)
