2009-10-20Remove default argument for ImpCastExprToType. Add appropriate argument Eli Friedman
to all callers. Switch a few other users of CK_Unknown to proper cast kinds. Note that there are still some situations where we end up with CK_Unknown; they're pretty easy to find with grep. There are still a few missing conversion kinds, specifically pointer/int/float->bool and the various combinations of real/complex float/int->real/complex float/int. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84623 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-21Change all the Type::getAsFoo() methods to specializations of Type::getAs().John McCall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82501 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-205 cleanups to ObjCObjectPointerType work:Steve Naroff
- Remove Sema::CheckPointeeTypesForAssignment(), a temporary API I added to ease migration to ObjCObjectPointerType. Convert Sema::CheckAssignmentConstraints() to no longer depend on the temporary API. - Sema::ConvertDeclSpecToType(): Replace a couple FIXME's with an important comment/example. - Sema::GetTypeForDeclarator(): Get the protocol's from the interface, NOT the declspec (to support the following C typedef idiom: "typedef C<P> T; T *obj"). - Sema::ObjCQualifiedIdTypesAreCompatible(): Removed some dead code. - ASTContext::getObjCEncodingForTypeImpl(): Some minor cleanups. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76443 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
2009-07-13Fix 5 issues from Chris's feedback on ↵Steve Naroff
http://llvm.org/viewvc/llvm-project?view=rev&revision=75314. Still more to come...just wanted to get the no-brainers out of the way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75477 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
2009-06-30De-ASTContext-ify DeclContext.Argyrios Kyrtzidis
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74506 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-17First step toward fixing <rdar://problem/6613046> refactor clang objc type ↵Steve Naroff
representation. Add a type (ObjCObjectPointerType) and remove a type (ObjCQualifiedIdType). This large/tedious patch is just a first step. 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73649 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-24PCH support for the global method pool (= instance and factory methodDouglas Gregor
pools, combined). The methods in the global method pool are lazily loaded from an on-disk hash table when Sema looks into its version of the hash tables. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69989 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-24Eliminate Sema::ObjCImplementations, relying instead on name lookup. What's ↵Douglas Gregor
good for uniformity is good for PCH (or is it the other way around?). As part of this, make ObjCImplDecl inherit from NamedDecl (since ObjCImplementationDecls now need to have names so that they can be found). This brings ObjCImplDecl very, very close to ObjCContainerDecl; we may be able to merge them soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69941 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Eliminate Sema::ObjCProtocols. Instead, we place ObjCProtocolDecls inDouglas Gregor
their own namespace (IDNS_Protocol) and use the normal name-lookup routines to find them. Aside from the simplification this provides (one less DenseMap!), it means that protocols will be lazily deserialized from PCH files. Make the code size of the selector table block match the code size of the type and decl blocks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69939 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Eliminate the three SmallVectors in ObjCImplDecl (for instanceDouglas Gregor
methods, class methods, and property implementations) and instead place all of these entities into the DeclContext. This eliminates more linear walks when looking for class or instance methods and should make PCH (de-)serialization of ObjCDecls trivial (and lazy). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69849 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-07Tweak Sema::ActOnInstanceMessage() to look for a class method when dealing ↵Steve Naroff
with qualified id's. This change is motivated by our desire to not support the "Class<foo>" idiom. Note that the change makes perfect sense (since all ObjC classes are also id/instances). This allow us to document a simple migration path...change "Class <foo>" to "id <foo>".
