2011-07-27[arcmt] More automatic transformations and safety improvements; rdar://9615812 :Argyrios Kyrtzidis
- 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 -zone is obsolete in ARC.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

2011-07-27Clean up the analysis of the collection operand to ObjCJohn McCall
for-in statements; specifically, make sure to close over any temporaries or cleanups it might require. In ARC, this has implications for the lifetime of the collection, so emit it with a retain and release it upon exit from the loop. rdar://problem/9817306 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136204 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-27In Microsoft mode, if we are within a templated function and we can't ↵Francois Pichet
resolve Identifier during BuildCXXNestedNameSpecifier, then extend the SS with Identifier. This will have the effect of resolving Identifier during template instantiation. The goal is to be able to resolve a function call whose nested-name-specifier is located inside a dependent base class. class C { public: static void foo2() { } }; template <class T> class A { public: typedef C D; }; template <class T> class B : public A<T> { public: void foo() { D::foo2(); } }; Note that this won't work if the NestedNameSpecifier refers to a type. This fixes 1 error when parsing the MSVC 2010 standard headers file with clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136203 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-26This patch implements as much of the narrowing conversion error specified byJeffrey Yasskin
[dcl.init.list] as is possible without generalized initializer lists or full constant expression support, and adds a c++0x-compat warning in C++98 mode. The FixIt currently uses a typedef's basename without qualification, which is likely to be incorrect on some code. If it's incorrect on too much code, we should write a function to get the string that refers to a type from a particular context. The warning is currently off by default. I'll fix LLVM and clang before turning it on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136181 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-26Disable the optimization that skips emission of complete, non-virtualDouglas Gregor
destructors of abstract classes. It's undefined behavior to actually call the destructor (e.g., via delete), but the presence of code that calls this destructor doesn't make the program ill-formed.

2011-07-26This patch extends the previous patch by starting to incorporate more ↵Jonathan D. Turner
functionality, like lookup-by-name and exporting lookup tables, into the module manager. Methods now have documentation. A few more functions have been switched over to the new iterator style and away from manual/explicit iteration. Ultimately we want to move away from name lookup here, as symlinks make filenames not a safe unique value, but we use it here as a stopgap before better measures are in place (namely instead using FileEntry* from a global FileManager). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136107 91177308-0d34-0410-b5e6-96231b3b80d8
