2012-03-08Implement C++11 [lex.ext]p10 for string and character literals: a ud-suffix notRichard Smith
starting with an underscore is ill-formed. Since this rule rejects programs that were using <inttypes.h>'s macros, recover from this error by treating the ud-suffix as a separate preprocessing-token, with a DefaultError ExtWarn. The approach of treating such cases as two tokens is under discussion for standardization, but is in any case a conforming extension and allows existing codebases to keep building while the committee makes up its mind. Reword the warning on the definition of literal operators not starting with underscores (which are, strangely, legal) to more explicitly state that such operators can't be called by literals. Remove the special-case diagnostic for hexfloats, since it was both triggering in the wrong cases and incorrect. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152287 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-08[libclang] Enhance clang_getOverriddenCursors.Argyrios Kyrtzidis
Basically the current design is: -for an implementation method, show as overridden the interface method. This is not useful, and is inconsistent with the C++ side -for an interface method, show as overridden the protocols methods (this is desirable) and the methods from the categories; methods from categories are not useful since they are considered the same method (same USR). -If there is a protocol method or category method reported, it does not check the super class for overridden methods. This is really problematic since overridden methods from super class is what we want to give back. Change clang_getOverriddenCursors to show as overridden any method in the class's base class, its protocols, or its categories' protocols, that has the same selector and is of the same kind (class or instance). If no such method exists, the search continues to the class's superclass, its protocols, and its categories, and so on. A method from an Objective-C implementation is considered to override the same methods as its corresponding method in the interface. rdar://10967206 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152270 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-07AST representation for user-defined literals, plus just enough of semanticRichard Smith
analysis to make the AST representation testable. They are represented by a new UserDefinedLiteral AST node, which is a sugared CallExpr. All semantic properties, including full CodeGen support, are achieved for free by this representation. UserDefinedLiterals can never be dependent, so no custom instantiation behavior is required. They are mangled as if they were direct calls to the underlying literal operator. This matches g++'s apparent behavior (but not its actual mangling, which is broken for literal-operator-ids). User-defined *string* literals are now fully-operational, but the semantic analysis is quite hacky and needs more work. No other forms of user-defined literal are created yet, but the AST support for them is present. This patch committed after midnight because we had already hit the quota for new kinds of literal yesterday. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152211 91177308-0d34-0410-b5e6-96231b3b80d8

By default, such a PCH file will be rejected with an error when trying to load it. [libclang] Allow clang_saveTranslationUnit to create a PCH file even if compiler errors occurred. -Have libclang API calls accept a PCH that had compiler errors.

2012-03-07Refactor Clang sema attribute handling.Michael Han
This submission improves Clang sema handling by using Clang tablegen to generate common boilerplate code. As a start, it implements AttributeList enumerator generation and case statements for AttributeList::getKind. A new field "SemaHandler" is introduced in Attr.td and by default set to 1 as most of attributes in Attr.td have semantic checking in Sema. For a small number of attributes that don't appear in Sema, the value is set to 0. Also there are a small number of attributes that only appear in Sema but not in Attr.td. Currently these attributes are still hardcoded in Sema AttributeList. Reviewed by Delesley Hutchins. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152169 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-07AST: fix build since r152060Dylan Noblesmith
The declarations of the operators no longer matched. The definitions in ASTContext.h had 'throw()' removed, but it was still present in Attr.h. Somehow the buildbots missed this. clang merely warns about a missing 'throw()' specification and suggested a Fix-It adding it back, but gcc 4.5 is not so forgiving and gives an error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152167 91177308-0d34-0410-b5e6-96231b3b80d8

the new Objective-C NSArray/NSDictionary/NSNumber literal syntax. This introduces a new library, libEdit, which provides a new way to support migration of code that improves on the original ARC migrator.

NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features.

2012-03-06AST: Move several Type::is...Type() functions to be inline.Daniel Dunbar
- These functions are both (a) very commonly called and (b) excellent candidates for CSE in the callers in which they are commonly used. - That isHalfType() is hot makes me sad, but it is trivially when inlined (and a huge waste of time when not!!!). - The extra IsEnumDeclComplete() function is a hack to break the cycle between Type.h and Decl.h, I'm not sure of how to do this more cleanly, but am open to ideas. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152126 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-05Fix a small difference in sema and codegen views of what needs to be output.Rafael Espindola
In the included testcase, soma thinks that we already have a definition after we see the out of line decl. Codegen puts it in a deferred list, to be output if a use is seen. This would break when we saw an explicit template instantiation definition, since codegen would not be notified.
