2009-07-16Avoid crashing for the enclosed test case.Steve Naroff
This is fallout from the recent ObjCObjectPointerType rework. I'll work on fixing this tomorrow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75870 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-15Handle some more fallout with the conversion of using PointerType forTed Kremenek
Objective-C pointers to using ObjCObjectPointerType. Now the checking for 'attribute ((nonnull))' in Sema doesn't emit an error when trying to apply that attribute to a parameter that is an Objective-C pointer (this is a regression). To prevent this regression from occuring in the future, the 'nonnull.c' test was moved to test/SemaObjC and renamed 'nonnull.m'. I also enhanced the tests to show that function calls involved a NULL Objective-C pointer constant does not trigger a warning. This is consistent with GCC, but should likely be fixed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75856 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-15Implement the ObjC pseudo built-in types as clang "BuiltinType's". I say ↵Steve Naroff
pseudo built-in types, since Sema still injects a typedef for recognition (i.e. they aren't truly built-ins from a parser perspective). This removes the static data/methods on ObjCObjectPointerType while preserving the nice API (no need to fiddle with ASTContext:-). This patch also adds Type::isObjCBuiltinType(). This should be the last fairly large patch related to recrafting the ObjC type system. The follow-on patches should be fairly small. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75808 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-14Add a "TypeSpecStartLoc" to FieldDecl. Patch contributed by Enea Zaffanella.Steve Naroff
Note: One day, it might be useful to consider adding this info to DeclGroup (as the comments in FunctionDecl/VarDecl suggest). For now, I think this works fine. I considered moving this to ValueDecl (a common ancestor of FunctionDecl/VarDecl/FieldDecl), however this would add overhead to EnumConstantDecl (which would burn memory and isn't necessary). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75635 91177308-0d34-0410-b5e6-96231b3b80d8

- Declaration context of ParmVarDecls (that we got from the Declarator) was not their containing function. - C++ out-of-line method definitions didn't get an access specifier.

2009-07-10This patch includes a conceptually simple, but very intrusive/pervasive change. Steve Naroff
The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches. This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic. By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time. Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75314 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-07Make ASTContext explicitly keep track of the declaration for the CDouglas Gregor
FILE type, rather than using name lookup to find FILE within the translation unit. Within precompiled headers, FILE is treated as yet another "special type" (like __builtin_va_list). This change should provide a performance improvement (not verified), since the lookup into the translation unit declaration forces the (otherwise unneeded) construction of a large hash table. More importantly, with precompiled headers, the construction of that table requires deserializing most of the top-level declarations from the precompiled header, which are then unused. Fixes PR 4509. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74911 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-02Add support for retrieving the Doxygen comment associated with a givenDouglas Gregor
declaration in the AST. The new ASTContext::getCommentForDecl function searches for a comment that is attached to the given declaration, and returns that comment, which may be composed of several comment blocks. Comments are always available in an AST. However, to avoid harming performance, we don't actually parse the comments. Rather, we keep the source ranges of all of the comments within a large, sorted vector, then lazily extract comments via a binary search in that vector only when needed (which never occurs in a "normal" compile). Comments are written to a precompiled header/AST file as a blob of source ranges. That blob is only lazily loaded when one requests a comment for a declaration (this never occurs in a "normal" compile). The indexer testbed now supports comment extraction. When the -point-at location points to a declaration with a Doxygen-style comment, the indexer testbed prints the associated comment block(s). See test/Index/comments.c for an example. Some notes: - We don't actually attempt to parse the comment blocks themselves, beyond identifying them as Doxygen comment blocks to associate them with a declaration. - We won't find comment blocks that aren't adjacent to the declaration, because we start our search based on the location of the declaration. - We don't go through the necessary hops to find, for example, whether some redeclaration of a declaration has comments when our current declaration does not. Similarly, we don't attempt to associate a \param Foo marker in a function body comment with the parameter named Foo (although that is certainly possible). - Verification of my "no performance impact" claims is still "to be done". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74704 91177308-0d34-0410-b5e6-96231b3b80d8
