- Replace calling -zone with 'nil'. -zone is obsolete in ARC.
- Allow removing retain/release on a static global var.
- Fix assertion hit when scanning for name references outside a NSAutoreleasePool scope.
- Automatically add bridged casts for results of objc method calls and when calling CFRetain, for example:
NSString *s;
CFStringRef ref = [s string]; -> CFStringRef ref = (__bridge CFStringRef)([s string]);
ref = s.string; -> ref = (__bridge CFStringRef)(s.string);
ref = [NSString new]; -> ref = (__bridge_retained CFStringRef)([NSString new]);
ref = [s newString]; -> ref = (__bridge_retained CFStringRef)([s newString]);
ref = [[NSString alloc] init]; -> ref = (__bridge_retained CFStringRef)([[NSString alloc] init]);
ref = [[s string] retain]; -> ref = (__bridge_retained CFStringRef)([s string]);
ref = CFRetain(s); -> ref = (__bridge_retained CFTypeRef)(s);
ref = [s retain]; -> ref = (__bridge_retained CFStringRef)(s);
- Emit migrator error when trying to cast to CF type the result of autorelease/release:
for
CFStringRef f3() {
return (CFStringRef)[[[NSString alloc] init] autorelease];
}
emits:
t.m:12:10: error: [rewriter] it is not safe to cast to 'CFStringRef' the result of 'autorelease' message; a __bridge cast may result in a pointer to a destroyed object and a __bridge_retained may leak the object
return (CFStringRef)[[[NSString alloc] init] autorelease];
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
t.m:12:3: note: [rewriter] remove the cast and change return type of function to 'NSString *' to have the object automatically autoreleased
return (CFStringRef)[[[NSString alloc] init] autorelease];
^
- Before changing attributes to weak/unsafe_unretained, check if the backing ivar
is set to a +1 object, in which case use 'strong' instead.

Language-design credit goes to a lot of people, but I particularly want
to single out Blaine Garst and Patrick Beard for their contributions.
Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself,
in no particular order.

- Kill unnecessary #includes in .cpp files. This is an automatic
sweep so some things removed are actually used, but happen to be
included by a previous header. I tried to get rid of the obvious
examples and this was the easiest way to trim the #includes in one
fell swoop.
- We now return to regularly scheduled development.
