2013-01-04[arcmt] Allow removing an -autorelease of a variable initialized in the ↵Argyrios Kyrtzidis
previous statement. rdar://11074996 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171485 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-04[arcmt] Adds brackets in case statements that "contain" initialization of ↵Argyrios Kyrtzidis
retaining variable, thus emitting the "switch case is in protected scope" error. rdar://12952016 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171484 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-08[arcmt] When we already removed a __weak, don't try to change it to ↵Argyrios Kyrtzidis

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 -zone is obsolete in ARC.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
2011-07-18[arcmt] NSInvocation's [get/set]ReturnValue and [get/set]Argument are only safeArgyrios Kyrtzidis
with __unsafe_unretained parameters. Emit error for strong/weak ones. rdar://9206226 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135381 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14[arcmt] Don't remove retains/releases on a global variable, flag them with ↵Argyrios Kyrtzidis
errors. rdar://9402555. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135213 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13[arcmt] For properties rewrite 'assign' -> 'weak or unsafe_unretained', ↵Argyrios Kyrtzidis
'retain' -> 'strong', and add 'weak or unsafe_unretained' when 'assign' is missing. rdar://9496219&9602589. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135065 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-12[arcmt] Before applying '__weak' check whether the objc class is annotated ↵Argyrios Kyrtzidis
with objc_arc_weak_reference_unavailable or is in a list of classes not supporting 'weak'. rdar://9489367. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135002 91177308-0d34-0410-b5e6-96231b3b80d8
