           Summary: Wrong code for delegate call
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: wrong-code
          Severity: major
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: maxim maxim-fomin.ru

import std.stdio;

struct S
{
    int i;
    void bar()
    {
        ++i;
    }
    void foo() immutable
    {
        void delegate() dg1 = &bar;
        dg1(); // comment out to fix

        void delegate() dg2;
        dg2.ptr = cast(void*)&this;
        dg2.funcptr = cast(void function())&S.bar;
        dg2();
    }
}

void main()
{
    immutable S s;
    writeln(s.i);
    s.foo();
    writeln(s.i);
}

Without dg1() call, dmd arranges registers's content correctly. However in
presence of dg1 call it incorrectly rearranges them so that [rex.W callq] calls
this pointer, not function pointer.
