2013-04-24[analyzer] IvarInvalidation: correctly handle cases where only partial ↵Anna Zaks
invalidators exist - If only partial invalidators exist and there are no full invalidators in @implementation, report every ivar that has not been invalidated. (Previously, we reported the first Ivar in the list, which could actually have been invalidated by a partial invalidator. The code assumed you cannot have only partial invalidators.) - Do not report missing invalidation method declaration if a partial invalidation method declaration exists. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180170 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-14objective-C: synthesize properties in order of theirFariborz Jahanian
declarations to synthesize their ivars in similar determinstic order so they are laid out in a determinstic order. // rdar://13192366 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175214 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-09[analyzer] Invalidation checker: move the "missing implementation" checkAnna Zaks
The missing definition check should be in the same category as the missing ivar validation - in this case, the intent is to invalidate in the given class, as described in the declaration, but the implementation does not perform the invalidation. Whereas the MissingInvalidationMethod checker checks the cases where the method intention is not to invalidate. The second checker has potential to have a much higher false positive rate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174787 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-08[analyzer] Split IvarInvalidation into two checkersAnna Zaks
Separate the checking for the missing invalidation methods into a separate checker so that it can be turned on/off independently. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174781 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-08[analyzer] IvarInvalidation: add annotation for partial invalidationAnna Zaks
The new annotation allows having methods that only partially invalidate IVars and might not be called from the invalidation methods directly (instead, are guaranteed to be called before the invalidation occurs). The checker is going to trust the programmer to call the partial invalidation method before the invalidator.This is common in cases when partial object tear down happens before the death of the object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174779 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-16Rework the traversal of Objective-C categories and extensions toDouglas Gregor
consider (sub)module visibility. The bulk of this change replaces myriad hand-rolled loops over the linked list of Objective-C categories/extensions attached to an interface declaration with loops using one of the four new category iterator kinds: visible_categories_iterator: Iterates over all visible categories and extensions, hiding any that have their "hidden" bit set. This is by far the most commonly used iterator. known_categories_iterator: Iterates over all categories and extensions, ignoring the "hidden" bit. This tends to be used for redeclaration-like traversals. visible_extensions_iterator: Iterates over all visible extensions, hiding any that have their "hidden" bit set. known_extensions_iterator: Iterates over all extensions, whether they are visible to normal name lookup or not. The effect of this change is that any uses of the visible_ iterators will respect module-import visibility. See the new tests for examples. Note that the old accessors for categories and extensions are gone; there are *Raw() forms for some of them, for those (few) areas of the compiler that have to manipulate the linked list of categories directly. This is generally discouraged. Part two of <rdar://problem/10634711>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172665 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-10[analyzer] Allow IvarInvalidation checker to suppress warnings viaAnna Zaks
assertions. To ensure that custom assertions/conditional would also be supported, just check if the ivar that needs to be invalidated or set to nil is compared against 0. Unfortunately, this will not work for code containing 'assert(IvarName)' git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172147 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-10[analyzer] Fix non-determinizm introduced in r172104.Anna Zaks
In some cases, we just pick any ivar that needs invalidation and attach the warning to it. Picking the first from DenseMap of pointer keys was triggering non-deterministic output. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172134 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-10[analyzer] Add more checks to the ObjC Ivar Invalidation checker.Anna Zaks
Restructured the checker so that it could easily find two new classes of issues: - when a class contains an invalidatable ivar, but no declaration of an invalidation method - when a class contains an invalidatable ivar, but no definition of an invalidation method in the @implementation. The second case might trigger some false positives, for example, when the method is defined in a category. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172104 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-07[analyzer] Fix a false positive in the ivar invalidation checker.Anna Zaks
When a property is "inherited" through both a parent class and directly through a protocol, we should not require the child to invalidate it since the backing ivar belongs to the parent class.

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

2012-09-29[analyzer] Re-implement IvarInvalidationChecker so that it verifies thatAnna Zaks
the validation occurred. The original implementation was pessimistic - we assumed that ivars which escape are invalidated. This version is optimistic, it assumes that the ivars will always be explicitly invalidated: either set to nil or sent an invalidation message. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164868 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-26[analyzer] Add experimental ObjC invalidation method checker.Anna Zaks
This checker is annotation driven. It checks that the annotated invalidation method accesses all ivars of the enclosing objects that are objects of type, which in turn contains an invalidation method. This is driven by __attribute((annotation("objc_instance_variable_invalidator")). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164716 91177308-0d34-0410-b5e6-96231b3b80d8
