From bb23d766bceccecc99280b543001bc70e16afbc9 Mon Sep 17 00:00:00 2001 From: Paul Phillips Date: Tue, 14 Feb 2012 22:04:30 -0800 Subject: Specialization action. The crickets at http://www.scala-lang.org/node/11901 were in unanimous agreement that I should proceed as suggested. - No arguments to @specialize gets you 10/10, not 9/10 - Fixed bugs in AnyRef specialization revealed by trying to use it - Specialized Function1 on AnyRef. - Changed AnyRef specialization to use OBJECT_TAG, not TVAR_TAG. - Deprecated SpecializableCompanion in favor of Specializable, which has the virtue of being public so it can be referenced from outside the library. - Cooked up mechanism to group specializable types so we don't have to repeat ourselves quite so much, and create a few groups for illustrative purposes. I'm not too serious about those names but I used up all my name-thinking-up brain for the day. - Updated genprod and friends since I had to regenerate Function1. - Put tests for a bunch of remaining specialization bugs in pending. Closes SI-4740, SI-4770, SI-5267. --- test/pending/pos/t4012.scala | 7 +++++++ 1 file changed, 7 insertions(+) create mode 100644 test/pending/pos/t4012.scala (limited to 'test/pending/pos/t4012.scala') diff --git a/test/pending/pos/t4012.scala b/test/pending/pos/t4012.scala new file mode 100644 index 0000000000..9b8a1b0dbe --- /dev/null +++ b/test/pending/pos/t4012.scala @@ -0,0 +1,7 @@ +trait C1[+A] { + def head: A = sys.error("") +} +trait C2[@specialized +A] extends C1[A] { + override def head: A = super.head +} +class C3 extends C2[Char] \ No newline at end of file -- cgit v1.2.3
