Summary:
In clang-tidy we'd like to know the name of the checker producing each
diagnostic message. PathDiagnostic has BugType and Category fields, which are
both arbitrary human-readable strings, but we need to know the exact name of the
checker in the form that can be used in the CheckersControlList option to
enable/disable the specific checker.
This patch adds the CheckName field to the CheckerBase class, and sets it in
the CheckerManager::registerChecker() method, which gets them from the
CheckerRegistry.
Checkers that implement multiple checks have to store the names of each check
in the respective registerXXXChecker method.

- 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.
llvm-svn: 180170
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.
llvm-svn: 174787
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.

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.

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)'
llvm-svn: 172147
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.
llvm-svn: 172134
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.
llvm-svn: 172104
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.

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.
llvm-svn: 169237
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.
llvm-svn: 164868
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")).
