[arcmt] More automatic transformations and safety improvements; rdar://9615812 : - 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 -zone is obsolete in ARC.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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136208 91177308-0d34-0410-b5e6-96231b3b80d8

Automatic Reference Counting. 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133103 91177308-0d34-0410-b5e6-96231b3b80d8

Give some convenient idiomatic accessors to Stmt::child_range and Stmt::const_child_range, then make a bunch of places use them instead of the individual iterator accessors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125450 91177308-0d34-0410-b5e6-96231b3b80d8

Fix bug in ParentMap::isConsumedExpr. A BinaryOperator always "consumes" the value of its subexpressions unless it is a comma (in which case it doesn't consume the left subexpression). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68628 91177308-0d34-0410-b5e6-96231b3b80d8

Fix: <rdar://problem/6740387>. Sending nil to an object that returns a struct should only be an error if that value is consumed. This fix was largely accomplished by moving 'isConsumedExpr' back to ParentMap. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68195 91177308-0d34-0410-b5e6-96231b3b80d8

More #include cleaning - 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54632 91177308-0d34-0410-b5e6-96231b3b80d8
