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
2009-07-17Replaced Type::getAsLValueReferenceType(), Type::getAsRValueReferenceType(), ↵Ted Kremenek
Type::getAsMemberPointerType(), Type::getAsTagType(), and Type::getAsRecordType() with their Type::getAs<XXX> equivalents. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76139 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
2009-07-14Introduce Type::isAnyPointerType() and convert all clients (suggested by Chris).Steve Naroff
I don't love the name, however it simplifies the code and is a worthwhile change. If/when we come up with a better name, we can do a search/replace. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75650 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10Remove some unused code from an experiment that I didn't like.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75315 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

Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating".

2009-06-22Rework the way we track which declarations are "used" duringDouglas Gregor
compilation, and (hopefully) introduce RAII objects for changing the "potentially evaluated" state at all of the necessary places within Sema and Parser. Other changes: - Set the unevaluated/potentially-evaluated context appropriately during template instantiation. - We now recognize three different states while parsing or instantiating expressions: unevaluated, potentially evaluated, and potentially potentially evaluated (for C++'s typeid). - When we're in a potentially potentially-evaluated context, queue up MarkDeclarationReferenced calls in a stack. For C++ typeid expressions that are potentially evaluated, we will play back these MarkDeclarationReferenced calls when we exit the corresponding potentially potentially-evaluated context. - Non-type template arguments are now parsed as constant expressions, so they are not potentially-evaluated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73899 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-19Keep track of when declarations are "used" according to C andDouglas Gregor
C++. This logic is required to trigger implicit instantiation of function templates and member functions of class templates, which will be implemented separately.

2009-05-20Introduce a new expression type, CXXUnresolvedConstructExpr, toDouglas Gregor
describe the construction of a value of a given type using function syntax, e.g., T(a1, a2, ..., aN) when the type or any of its arguments are type-dependent. In this case, we don't know what kind of type-construction this will be: it might construct a temporary of type 'T' (which might be a class or non-class type) or might perform a conversion to type 'T'. Also, implement printing of and template instantiation for this new expression type. Due to the change in Sema::ActOnCXXTypeConstructExpr, our existing tests cover template instantiation of this new expression node. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72176 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-14Implement explicit instantiations of member classes of class templates, e.g.,Douglas Gregor
template<typename T> struct X { struct Inner; }; template struct X<int>::Inner; This change is larger than it looks because it also fixes some a problem with nested-name-specifiers and tags. We weren't requiring the DeclContext associated with the scope specifier of a tag to be complete. Therefore, when looking for something like "struct X<int>::Inner", we weren't instantiating X<int>. This, naturally, uncovered a problem with member pointers, where we were requiring the left-hand side of a member pointer access expression (e.g., x->*) to be a complete type. However, this is wrong: the semantics of this expression does not require a complete type (EDG agrees). Stuart vouched for me. Blame him. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71756 91177308-0d34-0410-b5e6-96231b3b80d8

in C++, taking into account conversions to the "composite pointer type" so that we can compare, e.g., a pointer to a derived class to a pointer to a base class. Also, upgrade the "comparing distinct pointer types" from a warning to an error for C++, since this is clearly an error. Turns out that we hadn't gone through and audited this code for C++, ever.

2009-04-25This is a pretty big cleanup for how invalid decl/type are handle.Chris Lattner
This gets rid of a bunch of random InvalidDecl bools in sema, changing us to use the following approach: 1. When analyzing a declspec or declarator, if an error is found, we set a bit in Declarator saying that it is invalid. 2. Once the Decl is created by sema, we immediately set the isInvalid bit on it from what is in the declarator. From this point on, sema consistently looks at and sets the bit on the decl. This gives a very clear separation of concerns and simplifies a bunch of code. In addition to this, this patch makes these changes: 1. it renames DeclSpec::getInvalidType() -> isInvalidType(). 2. various "merge" functions no longer return bools: they just set the invalid bit on the dest decl if invalid. 3. The ActOnTypedefDeclarator/ActOnFunctionDeclarator/ActOnVariableDeclarator methods now set invalid on the decl returned instead of returning an invalid bit byref. 4. In SemaType, refering to a typedef that was invalid now propagates the bit into the resultant type. Stuff declared with the invalid typedef will now be marked invalid. 5. Various methods like CheckVariableDeclaration now return void and set the invalid bit on the decl they check. There are a few minor changes to tests with this, but the only major bad result is test/SemaCXX/constructor-recovery.cpp. I'll take a look at this next. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70020 91177308-0d34-0410-b5e6-96231b3b80d8
