* __builtin_object_size refinements. Ensure we handle expressions withMike Stump2009-10-271-2/+62
| | | | | | | | | | side-effects up front, as when we switch to the llvm intrinsic call for __builtin_object_size later, it will have two evaluations. We also finish off the intrinsic version of the code so we can just turn it on once llvm has the intrinsic. llvm-svn: 85324

* Change all the Type::getAsFoo() methods to specializations of Type::getAs().John McCall2009-09-211-5/+5
| | | | | | | | | | | Several of the existing methods were identical to their respective specializations, and so have been removed entirely. Several more 'leaf' optimizations were introduced. The getAsFoo() methods which imposed extra conditions, like getAsObjCInterfacePointerType(), have been left in place. llvm-svn: 82501

| | | | | | | | | | | | | | | | | | | | Type::getAsReferenceType() -> Type::getAs<ReferenceType>() Type::getAsRecordType() -> Type::getAs<RecordType>() Type::getAsPointerType() -> Type::getAs<PointerType>() Type::getAsBlockPointerType() -> Type::getAs<BlockPointerType>() Type::getAsLValueReferenceType() -> Type::getAs<LValueReferenceType>() Type::getAsRValueReferenceType() -> Type::getAs<RValueReferenceType>() Type::getAsMemberPointerType() -> Type::getAs<MemberPointerType>() Type::getAsReferenceType() -> Type::getAs<ReferenceType>() Type::getAsTagType() -> Type::getAs<TagType>() And remove Type::getAsReferenceType(), etc. This change is similar to one I made a couple weeks ago, but that was partly reverted pending some additional design discussion. With Doug's pending smart pointer changes for Types, it seemed natural to take this approach. llvm-svn: 77510
* This patch fixes the implementations of the __has_trivial_destructorDouglas Gregor2009-07-231-1/+1

* Per offline discussion with Steve Naroff, add back Type::getAsXXXType() methodsTed Kremenek2009-07-171-4/+4
| | | | | | | | | until Doug Gregor's Type smart pointer code lands (or more discussion occurs). These methods just call the new Type::getAs<XXX> methods, so we still have reduced implementation redundancy. Having explicit getAsXXXType() methods makes it easier to set breakpoints in the debugger. llvm-svn: 76193

| | | | | | Type::getAsMemberPointerType(), Type::getAsTagType(), and Type::getAsRecordType() with their Type::getAs<XXX> equivalents. llvm-svn: 76139
* Add member template 'Type::getAs<T>', which converts a Type* to a respective T*.Ted Kremenek2009-07-161-3/+3
| | | | | | | | | | | | | | | | | | | | | This method is intended to eventually replace the individual Type::getAsXXXType<> methods. The motivation behind this change is twofold: 1) Reduce redundant implementations of Type::getAsXXXType() methods. Most of them are basically copy-and-paste. 2) By centralizing the implementation of the getAs<Type> logic we can more smoothly move over to Doug Gregor's proposed canonical type smart pointer scheme. Along with this patch: a) Removed 'Type::getAsPointerType()'; now clients use getAs<PointerType>. b) Removed 'Type::getAsBlockPointerTypE()'; now clients use getAs<BlockPointerType>. llvm-svn: 76098
* Rename RecordLayout.h to ASTRecordLayout.hAnders Carlsson2009-07-141-1/+1

* This patch includes a conceptually simple, but very intrusive/pervasive change. Steve Naroff2009-07-101-1/+2
| | | | | | | | | | | | 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

* Implement Eli's feedback for vecto constant expressions;Nate Begeman2009-07-011-5/+52

* De-ASTContext-ify DeclContext.Argyrios Kyrtzidis2009-06-301-2/+2
| | | | | | | 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

| | | | | | | | | | | | | | "aligned" attribute. Previously, we were skipping over these attributes when we jumped directly to the canonical type. Now, ASTContext::getTypeInfo walks through typedefs and other "non-canonical" types manually, looking for "aligned" attributes on typedefs. As part of this change, I moved the GNU-specific logic (such as determining the alignment of void or of a function pointer) out of the expression evaluator and into ASTContext::getTypeInfo. llvm-svn: 70497
