* 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.

| | | | | | | | | | | | | | | | | | | | | | The original code came from 2008, (a4ace382), at which point we probably couldn't use JDK 1.5+ methods. I haven't changed `unsignedCompare` yet to use the standard library version, as it our version might have different performance characteristics.

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?)

In those cases, tail and possibly head were overridden so the head/tail pattern can be used with less of a performance penalty. Speed improvements on head/tail pattern are (for sets/maps of size 1024, unless otherwise specified): ``` BitSet 190x HashSet 250x Set 400x Set2 9x Set4 12x HashMap 430x ListMap 2500x // size 128 Map 430x ``` Note: `ListMap` is actually `init`/`last` because it's maintained in reverse order. Altered ListMap docs to explain that reverse traversal is the fast way to do it. All tested sets/maps that were already fast are still fast. Test code is reproduced below, except it does ListSet with head/tail which doesn't show the improvement: ```scala object BenchTailSetMap { val th = new ichi.bench.Thyme val standard = 1 to 1024 val sets = Map[String, Set[Int]]( "Set" -> (Set.empty[Int] ++ standard), "Set4"-> Set(4, 7, 2, 1), "Set2"-> Set(3, 4), "HashSet" -> (collection.immutable.HashSet.empty[Int] ++ standard), "BitSet" -> (collection.immutable.BitSet.empty ++ standard), "SortedSet" -> (collection.immutable.SortedSet.empty[Int] ++ standard), "ListSet" -> (collection.immutable.ListSet.empty[Int] ++ standard) ) val pairs = standard.map(i => i -> i.toString) // ListMap implementation is HORRIBLE, O(n^3) tail! Cut down size. val maps = Map[String, Map[Int, String]]( "Map" -> (Map.empty[Int, String] ++ pairs), "HashMap" -> (collection.immutable.HashMap.empty[Int, String] ++ pairs), "SortedMap" -> (collection.immutable.SortedMap.empty[Int, String] ++ pairs), "ListMap" -> (collection.immutable.ListMap.empty[Int, String] ++ pairs.take(128)) ) def hts(s: Set[Int]) = { var si = s var x = 0 while (si.nonEmpty) { x += si.head si = si.tail } x } def htm(m: Map[Int, String]) = { var mi = m var x = 0 while (mi.nonEmpty) { x += mi.head._2.length mi = mi.tail } x } def run() { sets.toList.sortBy(_._1).foreach{ case (name, s) => th.pbench(hts(s), s.size, name) } maps.toList.sortBy(_._1).foreach{ case (name, m) => th.pbench(htm(m), m.size, name) } } } ```
