2009-10-13When explicitly specializing a member that is a template, mark theDouglas Gregor
template as a specialization. For example, this occurs with: template<typename T> struct X { template<typename U> struct Inner { /* ... */ }; }; template<> template<typename T> struct X<int>::Inner { T member; }; We need to treat templates that are member specializations as special in two contexts: - When looking for a definition of a member template, we look through the instantiation chain until we hit the primary template *or a member specialization*. This allows us to distinguish between the primary "Inner" definition and the X<int>::Inner definition, above. - When computing all of the levels of template arguments needed to instantiate a member template, don't add template arguments from contexts outside of the instantiation of a member specialization, since the user has already manually substituted those arguments. Fix up the existing test for p18, which was actually wrong (but we didn't diagnose it because of our poor handling of member specializations of templates), and add a new test for member specializations of templates. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83974 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13Improve the internal representation and semantic analysis of friendDouglas Gregor
function templates. This commit ensures that friend function templates are constructed as FunctionTemplateDecls rather than partial FunctionDecls (as they previously were). It then implements template instantiation for friend function templates, injecting the friend function template only when no previous declaration exists at the time of instantiation. Oh, and make sure that explicit specialization declarations are not friends. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83970 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-13Teach sema and codegen about the difference between address of labels,Chris Lattner
which is a common idiom to improve PIC'ness of code using the addr of label extension. This implementation is a gross hack, but the only other alternative would be to teach evalutate about this horrid combination. While GCC allows things like "&&foo - &&bar + 1", people don't use this in practice. This implements PR5131. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83957 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13reimplement codegen for indirect goto with the following advantages:Chris Lattner
1. CGF now has fewer bytes of state (one pointer instead of a vector). 2. The generated code is determinstic, instead of getting labels in 'map order' based on pointer addresses. 3. Clang now emits one 'indirect goto switch' for each function, instead of one for each indirect goto. This fixes an M*N = N^2 IR size issue when there are lots of address-taken labels and lots of indirect gotos. 4. This also makes the default cause do something useful, reducing the size of the jump table needed (by one). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83952 91177308-0d34-0410-b5e6-96231b3b80d8
