2012-04-20Fix bug where a class's (deleted) copy constructor would be implicitly given aRichard Smith
non-const reference parameter type if the class had any subobjects with deleted copy constructors. This causes a rejects-valid if the class's copy constructor is explicitly defaulted (as happens for some implementations of std::pair etc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155218 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-19Thread safety analysis: split warnings into two groups: attribute warningsDeLesley Hutchins
which are checked in the parser, and analysis warnings that require the full analysis. This allows attribute syntax to be checked independently of the full thread safety analysis. Also introduces a new warning for the case where a string is used as a lock expression; this allows the analysis to gracefully handle expressions that would otherwise cause a parse error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155129 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-19In mergeVisibility, if we already have an explicit visibility, keep it.Rafael Espindola
This fixes the included testcase and lets us simplify the code a bit. It does require using mergeWithMin when merging class information to its members. Expand the comments to explain why that works. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155103 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-19In mergeVisibilityWithMin, let an implicit hidden symbol take precedence overRafael Espindola
an explicit default one. This means that with -fvisibility hidden we now produce a hidden symbol for template <typename T> class DEFAULT foo { void bar() {} }; class zed {}; template class foo<zed>; This matches the behaviour of gcc 4.7. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155102 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-19Now that we check visibility attributes in an appropriate order,Rafael Espindola
there is no need for mergeVisibily to ever increase the visibility. Not doing so lets us replace an incorrect use of mergeVisibilityWithMin. The testcase struct HIDDEN RECT { int top; }; DEFAULT RECT foo = {0}; shows that we should give preference to one of the attributes instead of keeping the minimum. We still get this testcase wrong because mergeVisibily handles two explicit visibilities incorrectly, but this is a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155101 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-17Switches the JSONCompilationDatabase to use the YAML parser.Manuel Klimek
This will allow us to delete the JSON parser from llvm. The biggest change is a general change of strategy - instead of storing StringRef's to the values for the command line and directory in the input buffer, we store ScalarNode*'s. The reason is that the YAML parser's getRawValue on ScalarNodes returns a string that includes the quotes in case of double quoted strings. For the same reason we're removing the JSON parsing part of the command line parsing - this means an extra copy for a command line when it is requested (and only when it is requested). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154929 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-17Implement DR1330 in C++11 mode, to support libstdc++4.7 which uses it.Richard Smith
We have a new flavor of exception specification, EST_Uninstantiated. A function type with this exception specification carries a pointer to a FunctionDecl, and the exception specification for that FunctionDecl is instantiated (if needed) and used in the place of the function type's exception specification. When a function template declaration with a non-trivial exception specification is instantiated, the specialization's exception specification is set to this new 'uninstantiated' kind rather than being instantiated immediately. Expr::CanThrow has migrated onto Sema, so it can instantiate exception specs on-demand. Also, any odr-use of a function triggers the instantiation of its exception specification (the exception specification could be needed by IRGen). In passing, fix two places where a DeclRefExpr was created but the corresponding function was not actually marked odr-used. We used to get away with this, but don't any more. Also fix a bug where instantiating an exception specification which refers to function parameters resulted in a crash. We still have the same bug in default arguments, which I'll be looking into next. This, plus a tiny patch to fix libstdc++'s common_type, is enough for clang to parse (and, in very limited testing, support) all of libstdc++4.7's standard headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154886 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-16Implement C++11 [expr.prim.general]p3, which permits the use of 'this'Douglas Gregor
in the declaration of a non-static member function after the (optional) cv-qualifier-seq, which in practice means in the exception specification and late-specified return type. The new scheme here used to manage 'this' outside of a member function scope is more general than the Scope-based mechanism previously used for non-static data member initializers and late-parsesd attributes, because it can also handle the cv-qualifiers on the member function. Note, however, that a separate pass is required for static member functions to determine whether 'this' was used, because we might not know that we have a static function until after declaration matching. Finally, this introduces name mangling for 'this' and for the implicit 'this', which is intended to match GCC's mangling. Independent verification for the new mangling test case would be appreciated. Fixes PR10036 and PR12450. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154799 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-13Implement the missing pieces needed to support libstdc++4.7's <atomic>:Richard Smith
__atomic_test_and_set, __atomic_clear, plus a pile of undocumented __GCC_* predefined macros. Implement library fallback for __atomic_is_lock_free and __c11_atomic_is_lock_free, and implement __atomic_always_lock_free. Contrary to their documentation, GCC's __atomic_fetch_add family don't multiply the operand by sizeof(T) when operating on a pointer type. libstdc++ relies on this quirk. Remove this handling for all but the __c11_atomic_fetch_add and __c11_atomic_fetch_sub builtins. Contrary to their documentation, __atomic_test_and_set and __atomic_clear take a first argument of type 'volatile void *', not 'void *' or 'bool *', and __atomic_is_lock_free and __atomic_always_lock_free have an argument of type 'const volatile void *', not 'void *'. With this change, libstdc++4.7's <atomic> passes libc++'s atomic test suite, except for a couple of libstdc++ bugs and some cases where libc++'s test suite tests for properties which implementations have latitude to vary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154640 91177308-0d34-0410-b5e6-96231b3b80d8

We should not deserialize unused declarations from the PCH file.
