* Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth2012-12-041-3/+3
| | | | | | | | | | | | | uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. llvm-svn: 169237
* Fix CXXRecordDecl::forallBases to not look through bases which are dependentRichard Smith2012-11-221-9/+3

* Fix typo correction of one qualified name to another.David Blaikie2012-10-121-1/+2
| | | | | | | | | | | | | | When suggesting "foo::bar" as a correction for "fob::bar" we mistakenly replaced only "bar" with "foo::bar" producing "fob::foo::bar" which was broken. This corrects that replacement in as many places as I could find & provides test cases for all those cases I could find a test case for. There are a couple that don't seem to be reachable (one looks entirely dead, the other just doesn't seem to ever get called with a namespace to namespace change).

* Move Sema::RequireCompleteType() and Sema::RequireCompleteExprType()Douglas Gregor2012-05-041-3/+2
| | | | | | | | | | | off PartialDiagnostic. PartialDiagnostic is rather heavyweight for something that is in the critical path and is rarely used. So, switch over to an abstract-class-based callback mechanism that delays most of the work until a diagnostic is actually produced. Good for ~11k code size reduction in the compiler and 1% speedup in -fsyntax-only on the code in <rdar://problem/11004361>. llvm-svn: 156176
* In C++11 mode, implement the C++11 semantics forDouglas Gregor2012-05-011-2/+5
| | | | | | | | | | | [basic.lookup.classref]p1 and p4, which concerns name lookup for nested-name-specifiers and template names, respectively, in a member access expression. C++98/03 forces us to look both in the scope of the object and in the current scope, then compare the results. C++11 just takes the result from the scope of the object, if something is found. Fixes <rdar://problem/11328502>. llvm-svn: 155935

| | | | | | | | | | | | | | | | | | | | | | | | resolve Identifier during BuildCXXNestedNameSpecifier, then extend the SS with Identifier. This will have the effect of resolving Identifier during template instantiation. The goal is to be able to resolve a function call whose nested-name-specifier is located inside a dependent base class. class C { public: static void foo2() { } }; template <class T> class A { public: typedef C D; }; template <class T> class B : public A<T> { public: void foo() { D::foo2(); } }; Note that this won't work if the NestedNameSpecifier refers to a type.

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. llvm-svn: 126765

* It turns out that basically every caller to RequireCompleteDeclContextJohn McCall2010-05-011-18/+9

* Make the InjectedClassNameType the canonical type of the current instantiationJohn McCall2010-04-271-55/+16
| | | | | | | | | | | | | | | | of a class template or class template partial specialization. That is to say, in template <class T> class A { ... }; or template <class T> class B<const T*> { ... }; make 'A<T>' and 'B<const T*>' sugar for the corresponding InjectedClassNameType when written inside the appropriate context. This allows us to track the current instantiation appropriately even inside AST routines. It also allows us to compute a DeclContext for a type much more efficiently, at some extra cost every time we write a template specialization (which can be optimized, but I've left it simple in this patch). llvm-svn: 102407

However, there are still benefits to typo-correcting with keywords: - We don't make stupid suggestions when the user typed something that is similar to a keyword. - We can suggest the keyword in a diagnostic (did you mean "static_cast"?), even if we can't recover and therefore don't have a fix-it. llvm-svn: 101274
