2009-09-25Use explicitly-specified template argument lists to help namingDouglas Gregor
explicit template specializations, when available. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82824 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-25Declarators can now properly represent template-ids, e.g., forDouglas Gregor
template void f<int>(int); ~~~~~~ Previously, we silently dropped the template arguments. With this change, we now use the template arguments (when available) as the explicitly-specified template arguments used to aid template argument deduction for explicit template instantiations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82806 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-24WIP implementation of explicit function template specialization. ThisDouglas Gregor
first implementation recognizes when a function declaration is an explicit function template specialization (based on the presence of a template<> header), performs template argument deduction + ambiguity resolution to determine which template is being specialized, and hooks There are many caveats here: - We completely and totally drop any explicitly-specified template arguments on the floor - We don't diagnose any of the extra semantic things that we should diagnose. - I haven't looked to see that we're getting the right linkage for explicit specializations On a happy note, this silences a bunch of errors that show up in libstdc++'s <iostream>, although Clang still can't get through the entire header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82728 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-24Refactor the representation of qualifiers to bring ExtQualType out of theJohn McCall
Type hierarchy. Demote 'volatile' to extended-qualifier status. Audit our use of qualifiers and fix a few places that weren't dealing with qualifiers quite right; many more remain. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82705 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-21Change all the Type::getAsFoo() methods to specializations of Type::getAs().John McCall
Several of the existing methods were identical to their respective specializations, and so have been removed entirely. Several more 'leaf' optimizations were introduced. The getAsFoo() methods which imposed extra conditions, like getAsObjCInterfacePointerType(), have been left in place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82501 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-16Improved representation and support for friend class templates. Angst about ↵John McCall

2009-09-15When implicitly declaring operators new, new[], delete, and delete[],Douglas Gregor
give them the appropriate exception specifications. This, unfortunately, requires us to maintain and/or implicitly generate handles to namespace "std" and the class "std::bad_alloc". However, every other approach I've come up with was more hackish, and this standard requirement itself is quite the hack. Fixes PR4829. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81939 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-13Perform the C++ specific semantic checks of a function declaration after ↵Anders Carlsson

2009-09-08Fix PR4922, where Sema would complete tentative definitions in nondeterminsticChris Lattner
order because it was doing so while iterating over a densemap. There are still similar problems in other places, for example WeakUndeclaredIdentifiers is still written to the PCH file in a nondeterminstic order, and we emit warnings about #pragma weak in nondeterminstic order. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81236 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-05Start emitting ElaboratedTypes in C++ mode. Support the effort in variousJohn McCall
ways: remove elab types during desugaring, enhance pretty-printing to allow tags to be suppressed without suppressing scopes, look through elab types when associating a typedef name with an anonymous record type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81065 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-30Improve diagnostics for missing members. This renames the ↵Anders Carlsson
err_typecheck_no_member to err_typecheck_no_member_deprecated.

2009-08-28Omnibus friend decl refactoring. Instead of cloning AST classes for friendJohn McCall
declarations of same, introduce a single AST class and add appropriate bits (encoded in the namespace) for whether a decl is "real" or not. Much hackery about previously-declared / not-previously-declared, but it's essentially mandated by the standard that friends alter lookup, and this is at least fairly non-intrusive. Refactor the Sema methods specific to friends for cleaner flow and less nesting. Incidentally solve a few bugs, but I remain confident that we can put them back. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80353 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-27Implement instantiation of the declarations of member functionDouglas Gregor
templates within class templates, producing a member function template of a class template specialization. If you can parse that, I'm sorry. Example: template<typename T> struct X { template<typename U> void f(T, U); }; When we instantiate X<int>, we now instantiate the declaration X<int>::f, which looks like this: template<typename U> void X<int>::f(int, U); The path this takes through TemplateDeclInstantiator::VisitCXXMethodDecl is convoluted and ugly, but I don't know how to improve it yet. I'm resting my hopes on the multi-level substitution required to instantiate definitions of nested templates, which may simplify this code as well. More testing to come... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80252 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-26When we know that we are parsing a class-name, implicitly construct aDouglas Gregor
TypenameType if getTypeName is looking at a member of an unknown specialization. This allows us to properly parse class templates that derived from type that could only otherwise be described by a typename type, e.g., template<class T> struct X {}; template<typename T> struct Y : public X<T>::X { }; Fixes PR4381. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80123 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-26Improve diagnostics and recovery when the nested-name-specifier of aDouglas Gregor
qualified name does not actually refer into a class/class template/class template partial specialization. Improve printing of nested-name-specifiers to eliminate redudant qualifiers. Also, make it possible to output a nested-name-specifier through a DiagnosticBuilder, although there are relatively few places that will use this leeway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80056 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-25Improve support for out-of-line definitions of nested templates andDouglas Gregor
their members, including member class template, member function templates, and member classes and functions of member templates. To actually parse the nested-name-specifiers that qualify the name of an out-of-line definition of a member template, e.g., template<typename X> template<typename Y> X Outer<X>::Inner1<Y>::foo(Y) { return X(); } we need to look for the template names (e.g., "Inner1") as a member of the current instantiation (Outer<X>), even before we have entered the scope of the current instantiation. Since we can't do this in general (i.e., we should not be looking into all dependent nested-name-specifiers as if they were the current instantiation), we rely on the parser to tell us when it is parsing a declaration specifier sequence, and, therefore, when we should consider the current scope specifier to be a current instantiation. Printing of complicated, dependent nested-name-specifiers may be somewhat broken by this commit; I'll add tests for this issue and fix the problem (if it still exists) in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80044 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-25Implement out-of-line definitions of nested class templates. Most ofDouglas Gregor
the logic is there for out-of-line definitions with multiple levels of nested templates, but this is still a work-in-progress: we're having trouble determining when we should look into a dependent nested-name-specifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80003 91177308-0d34-0410-b5e6-96231b3b80d8
