We won't synthesize a getter for such a property, but we will allow
the user to define a +1 method for it.

http://lab.llvm.org:8011/builders/clang-x86_64-darwin10-gdb went back green
before it processed the reverted 178663, so it could not have been the culprit.
Revert "Revert 178663."
This reverts commit 4f8a3eb2ce5d4ba422483439e20c8cbb4d953a41.
llvm-svn: 178682
For variables and functions clang used to store two storage classes. The one
"as written" in the code and a patched one, which, for example, propagates
static to the following decls.
This apparently is from the days clang lacked linkage computation. It is now
redundant and this patch removes it.

property which is not auto-synthesized.
Buttom line is that if hueristics determine
that there will be a user implemented setter,
no warning will be issued. // rdar://13388503

when property autosynthesis does not synthesize a property.
When property is declared 'readonly' in a super class and
is redeclared 'readwrite' in a subclass. When a property
autosynthesis causes it to share 'ivar' with another property.

lexical declarations looking for properties when we could more
efficiently check for property mismatches at property declaration
time. Good for ~1% of -fsyntax-only time when most of the properties
we're checking against come from an AST file.

did a redundant traversal of the lexical declarations in the
superclass. Instead, when we declare a new property, look into the
superclass to see whether we're redeclaring the property. Goot for 1%
of -fsyntax-only time on Cocoa.h and a little less than 3% on my
modules test case.

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.

has inconsistent ownership with the backing ivar, point the error location to the
ivar.
Pointing to the ivar (instead of the @synthesize) is better since this is where a fix is needed.
Also provide the location of @synthesize via a note.
This also fixes the problem where an auto-synthesized property would emit an error without
any location.

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.

source locations in places where it is necessary for diagnostics. By itself,
this causes assertions, so while I'm here, also fix property synthesis
for properties of C++ class type so we use so we properly set up a scope
and mark variable declarations.

Then, switch users of PropertyIfSetterOrGetter and LookupPropertyDecl
(the latter by name) over to findPropertyDecl. This actually makes
-Wreceiver-is-weak a bit stronger than it was before.
llvm-svn: 165628
Old algorithm:
1. See if the name looks like a getter or setter.
2. Use the name to look up a property in the current ObjCContainer
and all its protocols.
3. If the current container is an interface, also look in all categories
and superclasses (and superclass categories, and so on).
New algorithm:
1. See if the method is marked as a property accessor. If so, look through
all properties in the current container and find one that has a matching
selector.
2. Find all overrides of the method using ObjCMethodDecl's
getOverriddenMethods. This collects methods in superclasses and protocols
(as well as superclass categories, which isn't really necessary), and
checks if THEY are accessors. This part is not done recursively, since
getOverriddenMethods is already recursive.
This lets us handle getters and setters that do not match the property
names.
llvm-svn: 165627
This more accurately reflects its use: this flag is set when a method
matches the getter or setter name for a property in the same class,
and does not actually specify whether or not the definition of the method
will be synthesized (either implicitly or explicitly with @synthesize).
This renames the setter and backing field as well, and changes the
(soon-to-be-obsolete?) XML dump format to use 'property_accessor'
instead of 'synthesized'.
llvm-svn: 165626
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")).
