From 7d51b3fd1569917cb804363bd418466a306f5c89 Mon Sep 17 00:00:00 2001 From: Jason Zaugg Date: Mon, 6 Jun 2016 14:24:38 +1000 Subject: Emit trait method bodies in statics And use this as the target of the default methods or statically resolved super or $init calls. The call-site change is predicated on `-Yuse-trait-statics` as a stepping stone for experimentation / bootstrapping. I have performed this transformation in the backend, rather than trying to reflect this in the view from Scala symbols + ASTs. We also need to add an restriction related to invokespecial to Java parents: to support a super call to one of these to implement a super accessor, the interface must be listed as a direct parent of the class. The static method names has a trailing $ added to avoid duplicate name and signature errors in classfiles. --- test/files/run/t7700.scala | 16 +++++++++------- 1 file changed, 9 insertions(+), 7 deletions(-) (limited to 'test/files/run/t7700.scala') diff --git a/test/files/run/t7700.scala b/test/files/run/t7700.scala index 76d16b808c..fd13666467 100644 --- a/test/files/run/t7700.scala +++ b/test/files/run/t7700.scala @@ -7,11 +7,13 @@ trait C[@specialized U] { def bar[A](u: U) = u } -object Test extends App { - val declared = classOf[C[_]].getDeclaredMethods.sortBy(_.getName) - println(declared.mkString("\n")) - object CInt extends C[Int] { def foo(i: Int) = i } - object CAny extends C[Any] { def foo(a: Any) = a } - assert(CInt.foo(1) == 1) - assert(CAny.foo("") == "") +object Test { + def main(args: Array[String]) { + val declared = classOf[C[_]].getDeclaredMethods.sortBy(_.getName) + println(declared.mkString("\n")) + object CInt extends C[Int] { def foo(i: Int) = i } + object CAny extends C[Any] { def foo(a: Any) = a } + assert(CInt.foo(1) == 1) + assert(CAny.foo("") == "") + } } -- cgit v1.2.3
