2013-05-21Merging r182266:Bill Wendling
------------------------------------------------------------------------ r182266 | rnk | 2013-05-20 07:02:37 -0700 (Mon, 20 May 2013) | 13 lines Implement __declspec(selectany) under -fms-extensions selectany only applies to externally visible global variables. It has the effect of making the data weak_odr. The MSDN docs suggest that unused definitions can only be dropped at linktime, so Clang uses weak instead of linkonce. MSVC optimizes away references to constant selectany data, so it must assume that there is only one definition, hence weak_odr.

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.

2013-04-03Don'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

2013-02-26Be more careful in applying pragma weak. Fixes pr14974.Rafael Espindola
GCC applies a pragma weak to a decl if it matches the mangled name. We used to apply if it matched the plain name. This patch is a compromise: we apply the pragma only if it matches the name and the decl has C language linkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176110 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-26Unify clang/llvm attributes for asan/tsan/msan (Clang part)Kostya Serebryany
These are two related changes (one in llvm, one in clang). LLVM: - rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode) - rename thread_safety => sanitize_thread - rename no_uninitialized_checks -> sanitize_memory CLANG: - add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis)) - add __attribute__((no_sanitize_thread)) - add __attribute__((no_sanitize_memory)) for S in address thread memory If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not set llvm attribute sanitize_S git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176076 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-18Replace TypeLoc llvm::cast support to be well-defined.David Blaikie
The TypeLoc hierarchy used the llvm::cast machinery to perform undefined behavior by casting pointers/references to TypeLoc objects to derived types and then using the derived copy constructors (or even returning pointers to derived types that actually point to the original TypeLoc object). Some context is in this thread: http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-December/056804.html Though it's spread over a few months which can be hard to read in the mail archive. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175462 91177308-0d34-0410-b5e6-96231b3b80d8

MarkMemberReferenced instead of marking functions referenced directly. An audit of callers to MarkFunctionReferenced and DiagnoseUseOfDecl also caused a few other changes: * don't mark functions odr-used when considering them for an initialization sequence. Do mark them referenced though. * the function nominated by the cleanup attribute should be diagnosed. * operator new/delete should be diagnosed when building a 'new' expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174951 91177308-0d34-0410-b5e6-96231b3b80d8

Remove "IsMSDeclspec" argument from Align attribute since the arguments in Attr.td should only model those appear in source code.

the diagnostic's warn_ name. Switch some places (notably C++11 attributes) which really wanted an error over to a different diagnostic. Finally, suppress the diagnostic entirely for __ptr32, __ptr64 and __w64, to avoid producing diagnostics in important system headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173788 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-28Finish semantic analysis for [[carries_dependency]] attribute.Richard Smith
This required plumbing through a new flag to determine whether a ParmVarDecl is actually a parameter of a function declaration (as opposed to a function typedef etc, where the attribute is prohibited). Weirdly, this attribute (just like [[noreturn]]) cannot be applied to a function type, just to a function declaration (and its parameters). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173726 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-24PR14922: when printing an attribute, use the real syntax of the attribute ↵Michael Han
(GNU, C++11, MS Declspec) instead of hardcoded GNU syntax. Introduce a spelling index to Attr class, which is an index into the attribute spelling list of an attribute defined in Attr.td. This index will determine the actual spelling used by an attribute, as it incorporates both the syntax and naming of the attribute. When constructing an attribute AST node, the spelling index is computed based on attribute kind, scope (if it's a C++11 attribute), and name, then passed to Attr that will use the index to print itself. Thanks to Richard Smith for the idea and review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173358 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-12Disable caching of visibility.Rafael Espindola
The testcase in pr14929 shows that this is extremely hard to do. If we choose to apply the attribute, that causes the visibility of some decls to change and that can happen really late (during codegen). Current gcc warns and ignores the attribute in this testcase with a warning. This suggest that the correct solution is to find a point in the compilation where we can compute the visibility and * assert it was never computed before * reject any attempts to compute it again in the future (with warnings). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172305 91177308-0d34-0410-b5e6-96231b3b80d8
