This will let us do things like verify that tags match during template instantation, as well as signal that an elaborated type specifier was used for clients that actually care. Optimally, the TypeLoc hierarchy should be adjusted to carry tag location information as well. llvm-svn: 81057

* Implement the ObjC pseudo built-in types as clang "BuiltinType's". I say ↵Steve Naroff2009-07-151-0/+2
| | | | | | | | | | | | 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. llvm-svn: 75808

* This patch includes a conceptually simple, but very intrusive/pervasive change. Steve Naroff2009-07-101-1/+1
| | | | | | | | | | | | 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. llvm-svn: 75314
* Make ASTContext explicitly keep track of the declaration for the CDouglas Gregor2009-07-071-0/+1
| | | | | | | | | | | | | | | | | 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. llvm-svn: 74911
* Introduce the notion of "Relocatable" precompiled headers, which are builtDouglas Gregor2009-07-071-35/+94
| | | | | | | | | | | | with a particular system root directory and can be used with a different system root directory when the headers it depends on have been installed. Relocatable precompiled headers rewrite the file names of the headers used when generating the PCH file into the corresponding file names of the headers available when using the PCH file. Addresses <rdar://problem/7001604>. llvm-svn: 74885
* Keep track of the Expr used to describe the size of an array type,Douglas Gregor2009-07-061-0/+19

* Add support for retrieving the Doxygen comment associated with a givenDouglas Gregor2009-07-021-2/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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". llvm-svn: 74704
* De-ASTContext-ify DeclContext.Argyrios Kyrtzidis2009-06-301-5/+4
| | | | | | | Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating". Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit. llvm-svn: 74506

Next step is to remove ObjCQualifiedInterfaceType. After that, I will remove the magic TypedefType for 'id' (installed by Sema). This work will enable various simplifications throughout clang (when dealing with ObjC types). No functionality change. llvm-svn: 73649
