haxe's Issues

[analyzer_side_effect_rewrite] redundant temp var 

class Main {
    static function main() {}

    static function f(o1:{m:haxe.ds.IntMap<{f:Int}>}, o2:{f:Int}) {

        inline function get(o) return if (o > 0) o else 0;

        o1.m.get(0).f = get(o2.f);
    }
}

this branch:

Main.f = function(o1,o2) {
    var tmp = o1.m.h[0];
    var o = o2.f;
    tmp.f = o > 0?o:0;
};

current development:

Main.f = function(o1,o2) {
    var o = o2.f;
    o1.m.h[0].f = o > 0?o:0;
};

C++ broken

After merging development I'm seeing this:

Error: ./src/unit/MyList.cpp: In member function ‘virtual unit::MyList unit::MyList_obj::flatMap(Dynamic)’:
./src/unit/MyList.cpp:115:30: error: ‘T’ is not a member of ‘unit::MyList {aka hx::ObjectPtr<unit::MyList_obj>}’
./src/unit/MyList.cpp:115:30: error: ‘T’ is not a member of ‘unit::MyList {aka hx::ObjectPtr<unit::MyList_obj>}’
./src/unit/MyList.cpp:115:46: error: template argument 1 is invalid
./src/unit/MyList.cpp:155:32: error: ‘virtual unit::MyList unit::MyList_obj::flatMap(Dynamic)’ cannot appear in a constant-expression
./src/unit/MyList.cpp:155:43: error: template argument 1 is invalid

This suggests a broken AST, but the weird part is that the Java target works just fine.

Flash broken

I've seen that error in Haxe before, so it may or may not be a core issue. We should still try to find out what the problem is.

C# failing due to weird unit.Either type

So I've merged development branch into higher_kinded_types_reloaded today, which went surprisingly smooth. The Java target is working now, but C# fails with a Not_found exception. I printed that to find that it looks for unit.Either in a list of interfaces, which is very strange because from what I can tell that type is actually an enum.

The relevant lookup can be found here: https://github.com/Simn/haxe/blob/higher_kinded_types_reloaded/gencommon.ml#L4653

This suggests that we have a TInst where the class argument is an enum?! I don't know how to interpret this error.

@frabbit: Any idea?
