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 -zone is obsolete in ARC.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

2011-07-26Re-fix r136172 so it isn't an error; apparently, some people are fond of ↵Eli Friedman
their undefined behavior. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136183 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. Fixes <rdar://problem/9819242>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136180 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-26Diagnose trying to delete a pointer to an abstract class with a non-virtual ↵Eli Friedman
destructor. PR10504. I'm not completely sure the standard allows us to reject this, but if it doesn't, it should. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136172 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-26A couple minor issues with Sema for delete:Eli Friedman
1. Attempting to delete an expression of incomplete class type should be an error, not a warning. 2. If someone tries to delete a pointer to an incomplete class type, make sure we actually emit the delete expression after we warn. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136161 91177308-0d34-0410-b5e6-96231b3b80d8

@interface Foo : NSObject @property (readonly) id myProp; @end @implementation Foo @synthesize myProp; @end t.m:9:13: error: ARC forbids synthesizing a property of an Objective-C object with unspecified storage attribute @synthesize myProp; ^ which is fine, we want the ownership of the synthesized ivar to be explicit. But we should _not_ emit an error for the following cases, because we can get the ownership either from the declared ivar or from the property type: @interface Foo : NSObject { __weak id _myProp1; id myProp2; } @property (readonly) id myProp1; @property (readonly) id myProp2; @property (readonly) __strong id myProp3; @end @implementation Foo @synthesize myProp1 = _myProp1; @synthesize myProp2; @synthesize myProp3; @end  rdar://9844006. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136155 91177308-0d34-0410-b5e6-96231b3b80d8

PreprocessingRecord::getTotalMemory(). Most of the memory was already reported; but now we report more memory from side data structures. Fixes <rdar://problem/9379717>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136150 91177308-0d34-0410-b5e6-96231b3b80d8

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
