to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

A ConstantExpr class represents a full expression that's in a context where a
constant expression is required. This class reflects the path the evaluator
took to reach the expression rather than the syntactic context in which the
expression occurs.
In the future, the class will be expanded to cache the result of the evaluated
expression so that it's not needlessly re-evaluated

uncovered.
This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.
I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

track whether the referenced declaration comes from an enclosing
local context. I'm amenable to suggestions about the exact meaning
of this bit.

- 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 -zone is obsolete in ARC.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.
