2009-11-21This patch implements objective-c's 'SEL' type as a built-inFariborz Jahanian
type and fixes a long-standing code gen. crash reported in at least two PRs and a radar. (radar 7405040 and pr5025). There are couple of remaining issues that I would like for Ted. and Doug to look at: Ted, please look at failure in Analysis/MissingDealloc.m. I have temporarily added an expected-warning to make the test pass. This tests has a declaration of 'SEL' type which may not co-exist with the new changes. Doug, please look at a FIXME in PCHWriter.cpp/PCHReader.cpp. I think the changes which I have ifdef'ed out are correct. They need be considered for in a few Indexer/PCH test cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89561 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-21Added rudimentary C++0x attribute support.Sean Hunt
The following attributes are currently supported in C++0x attribute lists (and in GNU ones as well): - align() - semantics believed to be conformant to n3000, except for redeclarations and what entities it may apply to - final - semantics believed to be conformant to CWG issue 817's proposed wording, except for redeclarations - noreturn - semantics believed to be conformant to n3000, except for redeclarations - carries_dependency - currently ignored (this is an optimization hint) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89543 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-19Cope with an amusingly little anomaly with dependent types andDouglas Gregor
incomplete array initialization, where we have the following in a template: int a[] = { 1, 2, something-value-dependent }; // ... sizeof(a); The type of "a" appears to be a non-dependent IncompleteArrayType, but treating it as such makes the sizeof(a) fail at template definition time. We now correctly handle this by morphing the IncompleteArrayType into a DependentSizedArrayType with a NULL expression, indicating that its size has no corresponding expression (and, therefore, the type is distinct from others). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89366 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-18Incremental progress on using declarations. Split UnresolvedUsingDecl intoJohn McCall
two classes, one for typenames and one for values; this seems to have some support from Doug if not necessarily from the extremely-vague-on-this-point standard. Track the location of the 'typename' keyword in a using-typename decl. Make a new lookup result for unresolved values and deal with it in most places. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89184 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-16First part of changes to eliminate problems with cv-qualifiers andDouglas Gregor
sugared types. The basic problem is that our qualifier accessors (getQualifiers, getCVRQualifiers, isConstQualified, etc.) only look at the current QualType and not at any qualifiers that come from sugared types, meaning that we won't see these qualifiers through, e.g., typedefs: typedef const int CInt; typedef CInt Self; Self.isConstQualified() currently returns false! Various bugs (e.g., PR5383) have cropped up all over the front end due to such problems. I'm addressing this problem by splitting each qualifier accessor into two versions: - the "local" version only returns qualifiers on this particular QualType instance - the "normal" version that will eventually combine qualifiers from this QualType instance with the qualifiers on the canonical type to produce the full set of qualifiers. This commit adds the local versions and switches a few callers from the "normal" version (e.g., isConstQualified) over to the "local" version (e.g., isLocalConstQualified) when that is the right thing to do, e.g., because we're printing or serializing the qualifiers. Also, switch a bunch of Context.getCanonicalType(T1).getUnqualifiedType() == Context.getCanonicalType(T2).getQualifiedType() expressions over to Context.hasSameUnqualifiedType(T1, T2) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88969 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-11Template argument deduction for template template parameters. ThisDouglas Gregor
permits, among other things, ripping apart and reconstructing templates via partial specialization: template<typename T> struct DeepRemoveConst { typedef T type; }; template<typename T> struct DeepRemoveConst<const T> { typedef typename DeepRemoveConst<T>::type type; }; template<template<typename> class TT, typename T> struct DeepRemoveConst<TT<T> > { typedef TT<typename DeepRemoveConst<T>::type> type; }; Also, fix a longstanding thinko in the code handling partial ordering of class template partial specializations. We were performing the second deduction without clearing out the results of the first deduction. It's amazing we got through so much code with such a horrendous error :( git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86893 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11Introduce a new representation for template templateDouglas Gregor
parameters. Rather than storing them as either declarations (for the non-dependent case) or expressions (for the dependent case), we now (always) store them as TemplateNames. The primary change here is to add a new kind of TemplateArgument, which stores a TemplateName. However, making that change ripples to every switch on a TemplateArgument's kind, also affecting TemplateArgumentLocInfo/TemplateArgumentLoc, default template arguments for template template parameters, type-checking of template template arguments, etc. This change is light on testing. It should fix several pre-existing problems with template template parameters, such as: - the inability to use dependent template names as template template arguments - template template parameter default arguments cannot be instantiation However, there are enough pieces missing that more implementation is required before we can adequately test template template parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86777 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-22When building types from declarators, instead of building two types (one forJohn McCall
the DeclaratorInfo, one for semantic analysis), just build a single type whose canonical type will reflect the semantic analysis (assuming the type is well-formed, of course). To make that work, make a few changes to the type system: * allow the nominal pointee type of a reference type to be a (possibly sugared) reference type. Also, preserve the original spelling of the reference type. Both of these can be ignored on canonical reference types. * Remove ObjCProtocolListType and preserve the associated source information on the various ObjC TypeLocs. Preserve the spelling of protocol lists except in the canonical form. * Preserve some level of source type structure on parameter types, but canonicalize on the canonical function type. This is still a WIP. Drops code size, makes strides towards accurate source location representation, slight (~1.7%) progression on Cocoa.h because of complexity drop. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84907 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-18When performing template-substitution into a type, don't just replace theJohn McCall
TemplateTypeParmType with the substituted type directly; instead, replace it with a SubstTemplateTypeParmType which will note that the type was originally written as a template type parameter. This makes it reasonable to preserve source information even through template substitution. Also define the new SubstTemplateTypeParmType class, obviously. For consistency with current behavior, we stringize these types as if they were the underlying type. I'm not sure this is the right thing to do. At any rate, I paled at adding yet another clause to the don't-desugar 'if' statement, so I extracted a function to do it. The new function also does The Right Thing more often, I think: e.g. if we have a chain of typedefs leading to a vector type, we will now desugar all but the last one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84412 91177308-0d34-0410-b5e6-96231b3b80d8
