Clean up trivial default constructors now.

Also implement a fun standards bug regarding aggregates. Doug, if you'd
like, I can un-implement that bug if you think it is truly a defect.

The bug is that non-special-member constructors are never considered
user-provided, so the following is an aggregate:

struct foo {
  foo(int);
};

It's kind of bad, but the solution isn't obvious - should

struct foo {
  foo (int) = delete;
};

be an aggregate or not?

13 years agoRelax the conversion rules for Objective-C GC qualifiers a
Douglas Gregor [Sun, 8 May 2011 06:09:53 +0000 (06:09 +0000)]
Relax the conversion rules for Objective-C GC qualifiers a
bit by allowing __weak and __strong to be added/dropped as part of
implicit conversions (qualification conversions in C++). A little
history: GCC lets one add/remove/change GC qualifiers just about
anywhere, implicitly. Clang did roughly the same before, but we
recently normalized the semantics of qualifiers across the board to
get a semantics that we could reason about (yay). Unfortunately, this
tightened the screws a bit too much for GC qualifiers, where it's
common to add/remove these qualifiers at will.

Overall, we're still in better shape than we were before: we don't
permit directly changing the GC qualifier (e.g., __weak -> __strong),
so type safety is improved. More importantly, we're internally
consistent in our handling of qualifiers, and the logic that allows
adding/removing GC qualifiers (but not adding/removing address
spaces!) only touches two obvious places.
