2012-05-07Refactor DelayedDiagnostics so that it keeps diagnostics inJohn McCall
separate pools owned by the RAII objects that keep pushing decl state. This gives us quite a bit more flexibility. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156289 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-02Revert most of r154844, which was disabled in r155975. Keep around theRichard Smith
refactorings in that revision, and some of the subsequent bugfixes, which seem to be relevant even without delayed exception specification parsing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156031 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-16Implement the last part of C++ [class.mem]p2, delaying the parsing ofDouglas Gregor
exception specifications on member functions until after the closing '}' for the containing class. This allows, for example, a member function to throw an instance of its own class. Fixes PR12564 and a fairly embarassing oversight in our C++98/03 support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154844 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

2012-02-21Implement name mangling for lambda expressions that occur within theDouglas Gregor

2012-02-21Implement name mangling for lambda expressions that occur within theDouglas Gregor
default arguments of function parameters. This simple-sounding task is complicated greatly by two issues: (1) Default arguments aren't actually a real context, so we need to maintain extra state within lambda expressions to track when a lambda was actually in a default argument. (2) At the time that we parse a default argument, the FunctionDecl doesn't exist yet, so lambda closure types end up in the enclosing context. It's not clear that we ever want to change that, so instead we introduce the notion of the "effective" context of a declaration for the purposes of name mangling. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151011 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-07When we notice that a member function is defined with "= delete" or "=Douglas Gregor
default", make a note of which is used when creating the initial declaration.

2011-02-14When parsing an out-of-line member function declaration, we must delayJohn McCall
access-control diagnostics which arise from the portion of the declarator following the scope specifier, just in case access is granted by friending the individual method. This can also happen with in-line member function declarations of class templates due to templated-scope friend declarations. We were really playing fast-and-loose before with this sort of thing, and it turned out to work because *most* friend functions are in file scope. Making us delay regardless of context exposed several bugs with how we were manipulating delay. I ended up needing a concept of a context that's independent of the declarations in which it appears, and then I actually had to make some things save contexts correctly, but delay should be much cleaner now. I also encapsulated all the delayed-diagnostics machinery in a single subobject of Sema; this is a pattern we might want to consider rolling out to other components of Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125485 91177308-0d34-0410-b5e6-96231b3b80d8

used in the default function argument as "used". Instead, when we actually use the default argument, make another pass over the expression to mark any used declarations as "used" at that point. This addresses two kinds of related problems: 1) We were marking some declarations "used" that shouldn't be, because we were marking them too eagerly. 2) We were failing to mark some declarations as "used" when we should, if the first time it was instantiated happened to be an unevaluated context, we wouldn't mark them again at a later point.
