Fariborz Jahanian 6c9ee7b0c8 Objective-C. Issue more warning diagnostic when certain
properties are not synthesized in property auto-synthesis,
as it can potentiall lead to runtime errors.

Fariborz Jahanian b93355e9b1 Objective-C. deprecated attribute is not inherited on methods
overriden in interfaces and protocols (this is already the case
for properties). rdar://16068470

Ted Kremenek b79ee57080 Implemented delayed processing of 'unavailable' checking, just like with 'deprecated'.
Fixes <rdar://problem/15584219> and <rdar://problem/12241361>.

This change looks large, but all it does is reuse and consolidate
the delayed diagnostic logic for deprecation warnings with unavailability
warnings.  By doing so, it showed various inconsistencies between the
diagnostics, which were close, but not consistent.  It also revealed
some missing "note:"'s in the deprecated diagnostics that were showing
up in the unavailable diagnostics, etc.

This change also changes the wording of the core deprecation diagnostics.
Instead of saying "function has been explicitly marked deprecated"
we now saw "'X' has been been explicitly marked deprecated".  It
turns out providing a bit more context is useful, and often we
got the actual term wrong or it was not very precise
 (e.g., "function" instead of "destructor").  By just saying the name
of the thing that is deprecated/deleted/unavailable we define
this issue away.  This diagnostic can likely be further wordsmithed
to be shorter.

Ted Kremenek cb42dbe7ad Refine 'deprecated' checking for Objective-C classes/methods.
- If a deprecated class refers to another deprecated class, do not warn.
- @implementations of a deprecated class can refer to other deprecated things.

Fixes <rdar://problem/15407366> and <rdar://problem/15466783>.

Fariborz Jahanian f021889036 -Wdeprecated warning to include reference (as a note)
to the declaration in this patch. // rdar://10893232

Patrick Beard acfbe9e1f2 Added a new attribute, objc_root_class, which informs the compiler when a root class is intentionally declared.
The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger
the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698>

Ted Kremenek 6eb25628c5 Revert r145999. This turned out to be a bad idea. Unfortunately, 'id' is used so profusely
in many APIs and large codebases that this made the deprecated warning trigger happy to
the point of not being useful.

Richard Trieu 553b2b2e5d Modify how the -verify flag works. Currently, the verification string and
diagnostic message are compared.  If either is a substring of the other, then
no error is given.  This gives rise to an unexpected case:

  // expect-error{{candidate function has different number of parameters}}

will match the following error messages from Clang:

  candidate function has different number of parameters (expected 1 but has 2)
  candidate function has different number of parameters

It will also match these other error messages:

  candidate function
  function has different number of parameters
  number of parameters

This patch will change so that the verification string must be a substring of
the diagnostic message before accepting.  Also, all the failing tests from this
change have been corrected.  Some stats from this cleanup:

87 - removed extra spaces around verification strings
70 - wording updates to diagnostics
40 - extra leading or trailing characters (typos, unmatched parens or quotes)
35 - diagnostic level was included (error:, warning:, or note:)
18 - flag name put in the warning (-Wprotocol)

John McCall ad31b5f2cb Propagate the deprecated and unavailable attributes from a
@property declaration to the autogenerated methods.  I'm uncertain
whether this should apply to attributes in general, but these are
a reasonable core.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).
