2011-05-01Remove the type traits UTT_IsLvalueExpr and UTT_IsRvalueExpr.Chandler Carruth
As might be surmised from their names, these aren't type traits, they're expression traits. Amazingly enough, they're expression traits that we have, and fully implement. These "type" traits are even parsed from the same tokens as the expression traits. Luckily, the parser only tried the expression trait parsing for these tokens, so this was all just a pile of dead code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130643 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-23Implement basic __is_trivial type-trait support, enough to close PR9472.Chandler Carruth
This introduces a few APIs on the AST to bundle up the standard-based logic so that programmatic clients have access to exactly the same behavior. There is only one serious FIXME here: checking for non-trivial move constructors and move assignment operators. Those bits need to be added to the declaration and accessors provided. This implementation should be enough for the uses of __is_trivial in libstdc++ 4.6's C++98 library implementation. Ideas for more thorough test cases or any edge cases missing would be appreciated. =D git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130057 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-04Teach Sema::ActOnCXXNestedNameSpecifier and Sema::CheckTemplateIdTypeDouglas Gregor

2011-03-02Push nested-name-specifier source-location information into dependentDouglas Gregor
template specialization types. This also required some parser tweaks, since we were losing track of the nested-name-specifier's source location information in several places in the parser. Other notable changes this required: - Sema::ActOnTagTemplateIdType now type-checks and forms the appropriate type nodes (+ source-location information) for an elaborated-type-specifier ending in a template-id. Previously, we used a combination of ActOnTemplateIdType and ActOnTagTemplateIdType that resulted in an ElaboratedType wrapped around a DependentTemplateSpecializationType, which duplicated the keyword ("class", "struct", etc.) and nested-name-specifier storage. - Sema::ActOnTemplateIdType now gets a nested-name-specifier, which it places into the returned type-source location information. - Sema::ActOnDependentTag now creates types with source-location information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126808 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-01Reinstate the introduction of source-location information forDouglas Gregor
nested-name-speciciers within elaborated type names, e.g., enum clang::NestedNameSpecifier::SpecifierKind Fixes in this iteration include: (1) Compute the type-source range properly for a dependent template specialization type that starts with "template template-id ::", as in a member access expression dep->template f<T>::f() This is a latent bug I triggered with this change (because now we're checking the computed source ranges for dependent template specialization types). But the real problem was... (2) Make sure to set the qualifier range on a dependent template specialization type appropriately. This will go away once we push nested-name-specifier locations into dependent template specialization types, but it was the source of the valgrind errors on the buildbots. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126765 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-01Reinstate r126737, extending the generation of type-source locationDouglas Gregor
information for qualifier type names throughout the parser to address several problems. The commit message from r126737: Push nested-name-specifier source location information into elaborated name types, e.g., "enum clang::NestedNameSpecifier::SpecifierKind". Aside from the normal changes, this also required some tweaks to the parser. Essentially, when we're looking at a type name (via getTypeName()) specifically for the purpose of creating an annotation token, we pass down the flag that asks for full type-source location information to be stored within the returned type. That way, we retain source-location information involving nested-name-specifiers rather than trying to reconstruct that information later, long after it's been lost in the parser. With this change, test/Index/recursive-cxx-member-calls.cpp is showing much improved results again, since that code has lots of nested-name-specifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126748 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-24Retain complete source-location information for C++Douglas Gregor
nested-name-specifiers throughout the parser, and provide a new class (NestedNameSpecifierLoc) that contains a nested-name-specifier along with its type-source information. Right now, this information is completely useless, because we don't actually store the source-location information anywhere in the AST.

a pack expansion, e.g., the parameter pack Values in: template<typename ...Types> struct Outer { template<Types ...Values> struct Inner; }; This new implementation approach introduces the notion of an "expanded" non-type template parameter pack, for which we have already expanded the types of the parameter pack (to, say, "int*, float*", for Outer<int*, float*>) but have not yet expanded the values. Aside from creating these expanded non-type template parameter packs, this patch updates template argument checking and non-type template parameter pack instantiation to make use of the appropriate types in the parameter pack. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123845 91177308-0d34-0410-b5e6-96231b3b80d8
