2013-04-10Handle "typeof" in Objective-C format string checking. This previously crashed.Ted Kremenek
Yes, this came from actual code. Fixes <rdar://problem/13557053>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179155 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-10Add support for computing the exception specification for an inheritingRichard Smith
constructor. This isn't quite perfect (as usual, we don't handle default arguments correctly yet, and we don't deal with copy/move constructors for arguments correctly either, but this will be fixed when we implement core issue 1351. This completes our support for inheriting constructors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179154 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-10Suppress -Wunused-variable for variables declared in headers, which may inMatt Beaumont-Gay
fact be defined and used in another TU. Reshuffle some test cases because we suppress -Wunused-variable after we've emitted an error. This fixes PR15558. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179138 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-08<rdar://problem/13584715> Converted constant expressions are expected to ↵Douglas Gregor
have integral values. We were assuming that any expression used as a converted constant expression would either not have a folded constant value or would be an integer, which is not the case for some ill-formed constant expressions. Because converted constant expressions are only used where integral values are expected, we can simply treat this as an error path. If that ever changes, we'll need to widen the interface of Sema::CheckConvertedConstantExpression() anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179068 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-08<rdar://problem/13540899> Collect using directives from all of the semantic ↵Douglas Gregor
contexts not represented by scopes. This fixes a regression I introduced in r178136, where we would not consider the using directives from the semantic declaration contexts that aren't represented by the lexical scopes (Scope) when performing unqualified name lookup. This lead to horribly funny diagnostics like "no identifier named 'foo'; did you mean 'foo'?". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179067 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-06Rework how ObjC method inherit deprecated/availability.Ted Kremenek
New rule: - Method decls in @implementation are considered "redeclarations" and inherit deprecated/availability from the @interface. - All other cases are consider overrides, which do not inherit deprecated/availability. For example: (a) @interface redeclares a method in an adopted protocol. (b) A subclass redeclares a method in a superclass. (c) A protocol redeclares a method from another protocol it adopts. The idea is that API authors should have the ability to easily move availability/deprecated up and down a class/protocol hierarchy. A redeclaration means that the availability/deprecation is a blank slate.

2013-04-04Use isExternalLinkage instead of hasExternalLinkage.Rafael Espindola
Having these not be the same makes an easy to misuse API. We should audit the uses and probably rename to something like foo->hasExternalLinkage(): The c++ standard one. That is UniqueExternalLinkage or ExternalLinkage. foo->hasUniqueExternalLinkage(): Is UniqueExternalLinkage. foo->hasCogeGenExternalLinkage(): Is ExternalLinkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178768 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-04Fix a recent linkage regression.Rafael Espindola
Now that we don't have a semantic storage class, use the linkage. Thanks to Bruce Stephens for reporting this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178766 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-04Avoid computing the linkage instead of avoiding caching it.Rafael Espindola
This mostly reverts 178733, but keeps the tests. I don't claim to understand how hidden sub modules work or when we need to see them (is that documented?), but this has the same semantics and avoids adding hasExternalLinkageUncached which has the same foot gun potential as the old hasExternalLinkage. Last but not least, not computing linkage when it is not needed is more efficient. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178739 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-04Fix linkage related crash.Rafael Espindola
This test was exactly the opposite of what it should be. We should check if there old decl has linkage (where it makes sense) and if the new decl has the extern keyword. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178735 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-04Fix 41 of the 61 tests which fail with modules enabled: we were computing andRichard Smith
caching the linkage for a declaration before we set up its redeclaration chain, when determining whether a declaration could be a redeclaration of something from an unimported submodule. We actually want to look at the declaration as if it were not a redeclaration here, so compute the linkage but don't cache it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178733 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-03<rdar://problem/13560075> Teach name lookup for builtin names to find hidden ↵Douglas Gregor
declarations. Normal name lookup ignores any hidden declarations. When name lookup for builtin declarations fails, we just synthesize a new declaration at the point of use. With modules, this could lead to multiple declarations of the same builtin, if one came from a (hidden) submodule that was later made visible. Teach name lookup to always find builtin names, so we don't create these redundant declarations in the first place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178711 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-03Don't compute a patched/semantic storage class.Rafael Espindola
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178663 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-03Escape more @ signs in Doxygen comments.Jordan Rose

2013-04-02Add -Wstatic-local-in-inline, which warns about using a static localJohn McCall
