template partial specializations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73254 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-12Improve template argument deduction to keep track of why templateDouglas Gregor
argument deduction failed. For example, given template<typename T> struct is_same<T, T> { ... }; template argument deduction will fail for is_same<int, float>, and now reports enough information Right now, we don't do anything with this extra information, but it can be used for informative diagnostics that say, e.g., "template argument deduction failed because T was deduced to 'int' in one context and 'float' in another". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73237 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-12It's an error to use a function declared in a class definition as a default ↵Anders Carlsson
argument before the function has been declared. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73234 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-11Once we have deduced the template arguments of a class templateDouglas Gregor
partial specialization, substitute those template arguments back into the template arguments of the class template partial specialization to see if the results still match the original template arguments. This code is more general than it needs to be, since we don't yet diagnose C++ [temp.class.spec]p9. However, it's likely to be needed for function templates. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73196 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-10Template argument deduction for member pointers.Douglas Gregor

2009-06-05Start of a Sema implementation for #pragma weak. This isn't really theEli Friedman
right approach, but I'm still not sure what the best way to go about this is. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72912 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-05Several improvements to template argument deduction:Douglas Gregor
- Once we have deduced template arguments for a class template partial specialization, we use exactly those template arguments for instantiating the definition of the class template partial specialization. - Added template argument deduction for non-type template parameters. - Added template argument deduction for dependently-sized array types. With these changes, we can now implement, e.g., the remove_reference type trait. Also, Daniel's Ackermann template metaprogram now compiles properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72909 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04When performing template argument deduction, ensure that multipleDouglas Gregor
deductions of the same template parameter are equivalent. This allows us to implement the is_same type trait (!). Also, move template argument deduction into its own file and update a few build systems with this change (grrrr). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72819 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-31Initial infrastructure for class template partial specialization. HereDouglas Gregor
we have the basics of declaring and storing class template partial specializations, matching class template partial specializations at instantiation time via (limited) template argument deduction, and using the class template partial specialization's pattern for instantiation. This patch is enough to make a simple is_pointer type trait work, but not much else. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72662 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-30Remove VarDecl from CheckInitializerTypes now that CXXConstructExpr doesn't ↵Anders Carlsson
need to take a VarDecl anymore. (It still does, but it won't for long) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72630 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-30Add Sema::MaybeBindToTemporary which takes an expression and (if needed) ↵Anders Carlsson
wraps it in a CXXBindTemporaryExpr. Use this when creating CXXTemporaryObjectExprs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72629 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-29If a declarator group declares a type, make sure to add that declaration Eli Friedman
to the DeclGroup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72559 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-28When we parse a tag specifier, keep track of whether that tagDouglas Gregor
specifier resulted in the creation of a new TagDecl node, which happens either when the tag specifier was a definition or when the tag specifier was the first declaration of that tag type. This information has several uses, the first of which is implemented in this commit: 1) In C++, one is not allowed to define tag types within a type specifier (e.g., static_cast<struct S { int x; } *>(0) is ill-formed) or within the result or parameter types of a function. We now diagnose this. 2) We can extend DeclGroups to contain information about any tags that are declared/defined within the declaration specifiers of a variable, e.g., struct Point { int x, y, z; } p; This will help improve AST printing and template instantiation, among other things. 3) For C99, we can keep track of whether a tag type is defined within the type of a parameter, to properly cope with cases like, e.g., int bar(struct T2 { int x; } y) { struct T2 z; } We can also do similar things wherever there is a type specifier, e.g., to keep track of where the definition of S occurs in this legal C99 code: (struct S { int x, y; } *)0 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72555 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Reimplement much of the way that we track nested classes in theDouglas Gregor
parser. Rather than placing all of the delayed member function declarations and inline definitions into a single bucket corresponding to the top-level class, we instead mirror the nesting structure of the nested classes and place the delayed member functions into their appropriate place. Then, when we actually parse the delayed member function declarations, set up the scope stack the same way as it was when we originally saw the declaration, so that we can find, e.g., template parameters that are in scope. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72502 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Simplify, and improve the performance of, template instantiation forDouglas Gregor
declaration references. The key realization is that dependent Decls, which actually require instantiation, can only refer to the current instantiation or members thereof. And, since the current context during instantiation contains all of those members of the current instantiation, we can simply find the real instantiate that matches up with the "current instantiation" template. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72486 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-27Initial stab at a generalized operation for determining theDouglas Gregor
instantiation of a declaration from the template version (or version that lives in a template) and a given set of template arguments. This needs much, much more testing, but it suffices for simple examples like typedef T* iterator; iterator begin(); git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72461 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-20Introduce a new kind of RAII class, ASTOwningVector, which is anDouglas Gregor
