2009-07-29Change uses of:Ted Kremenek
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77510 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-17Per offline discussion with Steve Naroff, add back Type::getAsXXXType() methodsTed Kremenek
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76193 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-16Add member template 'Type::getAs<T>', which converts a Type* to a respective T*.Ted Kremenek
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>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76098 91177308-0d34-0410-b5e6-96231b3b80d8

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

2009-03-28Change compound assignment operators to keep track of both the promoted Eli Friedman
LHS type and the computation result type; this encodes information into the AST which is otherwise non-obvious. Fix Sema to always come up with the right answer for both of these types. Fix IRGen and the analyzer to account for these changes. This fixes PR2601. The approach is inspired by PR2601 comment 2. Note that this changes real *= complex in CodeGen from a silent miscompilation to an explicit error. I'm not really sure that the analyzer changes are correct, or how to test them... someone more familiar with the analyzer should check those changes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67889 91177308-0d34-0410-b5e6-96231b3b80d8
