2011-03-24Insomniac refactoring: change how the parser allocates attributes so thatJohn McCall

2011-03-16When we're inserting a synthesized label declaration for aDouglas Gregor
forward-looking "goto" statement, make sure to insert it *after* the last declaration in the identifier resolver's declaration chain that is either outside of the function/block/method's scope or that is declared in that function/block/method's specific scope. Previously, we could end up inserting the label ahead of declarations in inner scopes, confusing C++ name lookup. Fixes PR9491/<rdar://problem/9140426> and <rdar://problem/9135994>. Note that the crash-on-invalid PR9495 is *not* fixed. That's a separate issue. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127737 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-14When synthesizing a label declaration based on a goto statement thatDouglas Gregor
cannot yet be resolved, be sure to push the new label declaration into the right place within the identifier chain. Otherwise, name lookup in C++ gets confused when searching for names that are lexically closer than the label.

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

2011-02-17Step #2/N of __label__ support: keep pushing LabelDecl forward,Chris Lattner
making them be template instantiated in a more normal way and make them handle attributes like other decls.

2011-02-17Step #1/N of implementing support for __label__: split labels intoChris Lattner
LabelDecl and LabelStmt. There is a 1-1 correspondence between the two, but this simplifies a bunch of code by itself. This is because labels are the only place where we previously had references to random other statements, causing grief for AST serialization and other stuff. This does cause one regression (attr(unused) doesn't silence unused label warnings) which I'll address next. This does fix some minor bugs: 1. "The only valid attribute " diagnostic was capitalized. 2. Various diagnostics printed as ''labelname'' instead of 'labelname' 3. This reduces duplication of label checking between functions and blocks. Review appreciated, particularly for the cindex and template bits. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125733 91177308-0d34-0410-b5e6-96231b3b80d8
