2012-01-27Avoid redundant NNS qualification in constructor/destructor names.Abramo Bagnara
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149124 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-18constexpr: converted constant expression handling for enumerator values, caseRichard Smith
values and non-type template arguments of integral and enumeration types. This change causes some legal C++98 code to no longer compile in C++11 mode, by enforcing the C++11 rule that narrowing integral conversions are not permitted in the final implicit conversion sequence for the above cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148439 91177308-0d34-0410-b5e6-96231b3b80d8

appropriate or when GCC requires it) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148292 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-14De-virtualize getPreviousDecl() and getMostRecentDecl() when we knowDouglas Gregor
we have a redeclarable type, and only use the new virtual versions (getPreviousDeclImpl() and getMostRecentDeclImpl()) when we don't have that type information. This keeps us from penalizing users with strict type information (and is the moral equivalent of a "final" method). Plus, settle on the names getPreviousDecl() and getMostRecentDecl() throughout. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148187 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-14Introduce Decl::getPreviousDecl() and Decl::getMostRecentDecl(),Douglas Gregor
virtual functions that provide previous/most recent redeclaration information for any declaration. Use this to eliminate the redundant, less efficient getPreviousDecl() functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148184 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-13Convert SemaTemplate*.cpp to pass a callback object to CorrectTypo.Kaelyn Uhrain
The change to SemaTemplateVariadic.cpp improves the typo correction results in certain situations, while the change to SemaTemplate.cpp does not change existing behavior. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148155 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-23Fix several issues related to specializations and explicit instantiations.Nico Weber
Explicit instantiations following specializations are no-ops and hence have no PointOfInstantiation. That was done correctly in most cases, but for a specialization -> instantiation decl -> instantiation definition chain, the definition didn't realize that it was a no-op. Fix that. Also, when printing diagnostics for these no-ops, get the diag location from the decl name location. Add many test cases, one of them not yet passing (but it failed the same way before this change). Fixes http://llvm.org/pr11558 and more. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147225 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-20When performing name lookup for a redeclaration, ignore moduleDouglas Gregor
visibility restrictions. This ensures that all declarations of the same entity end up in the same redeclaration chain, even if some of those declarations aren't visible. While this may seem unfortunate to some---why can't two C modules have different functions named 'f'?---it's an acknowedgment that a module does not introduce a new "namespace" of names. As part of this, stop merging the 'module-private' bit from previous declarations to later declarations, because we want each declaration in a module to stand on its own because this can effect, for example, submodule visibility. Note that this notion of names that are invisible to normal name lookup but are available for redeclaration lookups is how we should implement friend declarations and extern declarations within local function scopes. I'm not tackling that problem now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146980 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. Previously, we would wait until later to handle default/delete as a definition, but this is too late: when adding the declaration, we already treated the declaration as "user-provided" when in fact it was merely "user-declared". Fixes PR10861 and PR10442, along with a bunch of FIXMEs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144011 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-03When we're checking a friend function template in an out-of-line classDouglas Gregor
definition, we may not have a scope corresponding to the namespace where that friend function template actually lives. Work around this issue by faking up a scope with the appropriate DeclContext. This is a bit of a hack, but it fixes <rdar://problem/10204947>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143614 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-01When we see an out-of-line definition of a member class template thatDouglas Gregor
does not match any declaration in the class (or class template), be sure to mark it as invalid. Fixes PR10924 / <rdar://problem/10119422>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143504 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-27Fix some cases where a CK_IntegralCast was being used to convert an lvalue to anRichard Smith
rvalue. An assertion to catch this is in ImpCastExprToType will follow, but vector operations currently trip over this (due to omitting the usual arithmetic conversions). Also add an assert to catch missing lvalue-to-rvalue conversions on the LHS of ->. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143155 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25Check for unexpanded parameter packs in the name that guards aDouglas Gregor
Microsoft __if_exists/__if_not_exists statement. Also note that we weren't traversing DeclarationNameInfo *at all* within the RecursiveASTVisitor, which would be rather fatal for variadic templates. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142906 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-20There's no point in marking a declaration invalid just because itDouglas Gregor
shadows a template parameter. Complain about the shadowing (or not, under -fms-extensions), but don't invalidate the declaration. Merely forget about the template parameter declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142596 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-14Implement function template specialization at class scope extension in ↵Francois Pichet
Microsoft mode. A new AST node is introduced: ClassScopeFunctionSpecialization. This node holds a FunctionDecl that is not yet specialized; then during the class template instantiation the ClassScopeFunctionSpecialization will spawn the actual function specialization. Example: template <class T> class A { public: template <class U> void f(U p) { } template <> void f(int p) { } // <== class scope specialization }; This extension is necessary to parse MSVC standard C++ headers, MFC and ATL code. BTW, with this feature in, clang can parse (-fsyntax-only) all the MSVC 2010 standard header files without any error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137573 91177308-0d34-0410-b5e6-96231b3b80d8
