|\ | | | | the scanner is now less eager about deprecations
| * changes the flags to not depend on partestEugene Burmako2012-12-281-1/+1
| | | | | | | | | | | | Due to some reason, partest always enables -deprecation. Since Paul has just submitted a pull request, which removes this behavior, I'm updating the flags to make sure this test works even after Paul's change.
| * the scanner is now less eager about deprecationsEugene Burmako2012-12-253-0/+20
| | | | | | | | | | | | When healing braces it isn't very useful to report deprecation warnings, especially since this process is just simple context-free skimming, which can't know about what positions can accept what identifiers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Investigating the useful output of devWarning (-Xdev people, it's good for you) led back to this comment: "normalize to get rid of type aliases" You may know that this is not all the normalizing does. Normalizing also turns TypeRefs with unapplied arguments (type constructors) into PolyTypes. That means that when typedParentType would call typedTypeConstructor it would find its parent had morphed into a PolyType. Not that it noticed; it would blithely continue and unwittingly discard the type arguments by way of appliedType (which smoothly logged the incident, thank you appliedType.) The simplification of typedTypeConstructor: There was a whole complicated special treatment of AnyRef here which appears to have become unnecessary. Removed special treatment and lit a candle for regularity. Updated lots of tests regarding newly not-so-special AnyRef.

Uncurry was using fresh names for the apply method parameters during Function expansion. (The parameter names in the tree were actually correct, they just had synthetic symbols with "x$1" etc.) 2. When adding specialized overrides, the parameter names of the overriden method were used, rather than the parameter names from the overriding method in the class to which we are adding methods. The upshot of this is that when you're stopped in the debugger in the body of, say, `(i: Int) => i * i`, you see `v1` rather than `i`. This commit changes Uncurry and SpecializeTypes to remedy this.

It checks whether a parent can have value arguments or not and more importantly, it synthesizes constructors and super calls. This approach is fundamentally incompatible with upcoming type macros. Take for example the following two snippets of code: `class C extends A(2)` `class D extends A(2) with B(3)` In the first snippet, `A` might be a type macro, therefore the super call `A.super(2)` eagerly emitted by the parser might be meaningless. In the second snippet parser will report an error despite that `B` might be a type macro which expands into a trait. Unfortunately we cannot simply augment the parser with the `isTypeMacro` check. This is because to find out whether an identifier refers to a type macro, one needs to perform a typecheck, which the parser cannot do. Therefore we need a deep change in how parent types and constructors are processed by the compiler, which is implemented in this commit.
