| * | | | | SI-6710 / PR 5072 follow-up: fix Unit.box / Unit.unboxLukas Rytz2016-04-204-10/+133
| |/ / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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`.

| * | | | | Inline ScalaRunTime.arrayElementClass at call sites.Sébastien Doeraene2016-04-137-33/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | | | Remove dead-code runtime hash() methods.Sébastien Doeraene2016-04-136-94/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Doeraene2016-04-133-44/+18
| |/ / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This happens for Java annotations: the annotation type and `classOf` annotation arguments are not erased, the annotationInfos of a symbol are not touched in the compiler pipeline. - If T is an alias to a value class, ensure that `classOf[T]` erases to the value class by calling `dealiasWiden` in erasure.

Stripping is sound when the expected type is `Function0` for this expression, but that's no longer a given, since we could be expecting any nullary SAM. Also sweep up a bit around `typedEta`. Encapsulate the, erm, creative encoding of `m _` as `Typed(m, Function(Nil, EmptyTree))`.
