2011-09-13[PCH] Fix a regression that r139441 introduced (decls were getting passedArgyrios Kyrtzidis
to the consumer without being fully deserialized). The regression was on compiling boost.python and it was too difficult to get a reduced test case unfortunately. Also modify the logic of how objc methods are getting passed to the consumer; codegen depended on receiving objc methods before the implementation decl. Since the interesting objc methods are ones with a body and such methods only exist inside an ObjCImplDecl, deserialize and pass to consumer all the methods of ObCImplDecl when we see one. Fixes http://llvm.org/PR10922 & rdar://10117105. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139644 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Switch LangOptions over to a .def file that describes header of theDouglas Gregor
language options. Use that .def file to declare the LangOptions class and initialize all of its members, eliminating a source of annoying initialization bugs. AST serialization changes are next up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139605 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-10Clean up our handling of Objective-C definitions in AST files. RatherDouglas Gregor
than having CodeGen check whether a declaration comes from an AST file (which it shouldn't know or care about), make sure that the AST writer and reader pass along "interesting" declarations that CodeGen needs to know about. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139441 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-08Allow C++0x enumerations with a fixed underlying type inDouglas Gregor
Objective-C. The @encode'ing of such an enumeration type is the same as its underlying type. <rdar://problem/5276348>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139297 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-08Implement the Objective-C 'instancetype' type, which is an alias ofDouglas Gregor
'id' that can be used (only!) via a contextual keyword as the result type of an Objective-C message send. 'instancetype' then gives the method a related result type, which we have already been inferring for a variety of methods (new, alloc, init, self, retain). Addresses <rdar://problem/9267640>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139275 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02Extend the ASTContext constructor to delay the initialization ofDouglas Gregor
builtin types (When requested). This is another step toward making ASTUnit build the ASTContext as needed when loading an AST file, rather than doing so after the fact. No actual functionality change (yet). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138985 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01Teach ASTContext and Preprocessor to hold on to references to the sameDouglas Gregor
LangOptions, rather than making distinct copies of LangOptions. Granted, LangOptions doesn't actually get modified, but this will eventually make it easier to construct ASTContext and Preprocessor before we know all of the LangOptions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138959 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-14Implement function template specialization at class scope extension in ↵Francois Pichet
Microsoft mode. A new AST node is introduced: ClassScopeFunctionSpecialization. This node holds a FunctionDecl that is not yet specialized; then during the class template instantiation the ClassScopeFunctionSpecialization will spawn the actual function specialization. Example: template <class T> class A { public: template <class U> void f(U p) { } template <> void f(int p) { } // <== class scope specialization }; This extension is necessary to parse MSVC standard C++ headers, MFC and ATL code. BTW, with this feature in, clang can parse (-fsyntax-only) all the MSVC 2010 standard header files without any error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137573 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12metadata generated by the compiler does not include the weak Fariborz Jahanian

2011-08-12Switch the __int128_t and __uint128_t types over to predefined typesDouglas Gregor
in the AST format, which are built lazily by the ASTContext when requested. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137437 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12Switch the Objective-C 'SEL' type over to a predefined type in theDouglas Gregor

2011-08-12Move the creation of the predefined typedef for Objective-C's 'id'Douglas Gregor
type over into the AST context, then make that declaration a predefined declaration in the AST format. This ensures that different AST files will at least agree on the (global) declaration ID for 'id', and eliminates one of the "special" types in the AST file format. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137429 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-11Encapsulate the Objective-C id/Class/SEL "redefinition" types inDouglas Gregor
ASTContext with accessors/mutators. The only functional change is that the AST writer won't bother writing the id/Class/SEL redefinition type if it hasn't been explicitly set; previously, it ended up being written as a synonym for the built-in id/Class/SEL. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137349 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-09Move the creation of the record type for the state of Objective-C fastDouglas Gregor
enumerations from the ASTContext into CodeGen, so that we don't need to serialize it to AST files. This appears to be the last of the low-hanging fruit for SpecialTypes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137124 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-09Don't serialize the block descriptor or block extended descriptorDouglas Gregor
types to AST files; they're only used by debug info generation anyway, and shouldn't ever exist in the AST anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137122 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-09Move the construction of the RecordDecl representing the runtimeDouglas Gregor
layout of a constant NSString from the ASTContext over to CodeGen, since this is solely CodeGen's responsibility. Eliminates one of the unnecessary "special" types that we serialize. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137121 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-22Add a const overload for ObjCInterfaceDecl::all_declared_ivar_begin.Jordy Rose
This was previously not-const only because it has to lazily construct a chain of ivars the first time it is called (and after the chain is invalidated). In practice, all the clients were just const_casting their const Decls; all those now-unnecessary const_casts have been removed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135741 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-01[ARC] When casting from a pointer to an objective-c object with known ↵Argyrios Kyrtzidis
ownership, if the cast type has no ownership specified, implicitly "transfer" the ownership of the cast'ed type to the cast type: id x; static_cast<NSString**>(&x); // Casting as (__strong NSString**).

2011-07-01Introduce the notion of instantiation dependence into Clang's AST. ADouglas Gregor
type/expression/template argument/etc. is instantiation-dependent if it somehow involves a template parameter, even if it doesn't meet the requirements for the more common kinds of dependence (dependent type, type-dependent expression, value-dependent expression). When we see an instantiation-dependent type, we know we always need to perform substitution into that instantiation-dependent type. This keeps us from short-circuiting evaluation in places where we shouldn't, and lets us properly implement C++0x [temp.type]p2. In theory, this would also allow us to properly mangle instantiation-dependent-but-not-dependent decltype types per the Itanium C++ ABI, but we aren't quite there because we still mangle based on the canonical type in cases like, e.g., template<unsigned> struct A { }; template<typename T> void f(A<sizeof(sizeof(decltype(T() + T())))>) { } template void f<int>(A<sizeof(sizeof(int))>); and therefore get the wrong answer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134225 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-15Eliminate a 'default' case in template argument deduction, where weDouglas Gregor
were just punting on template argument deduction for a number of type nodes. Most of them, obviously, didn't matter. As a consequence of this, make extended vector types (via the ext_vector_type attribute) actually work properly for several important cases: - If the attribute appears in a type-id (i.e, not attached to a typedef), actually build a proper vector type - Build ExtVectorType whenever the size is constant; previously, we were building DependentSizedExtVectorType when the size was constant but the type was dependent, which makes no sense at all. - Teach template argument deduction to handle ExtVectorType/DependentSizedExtVectorType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133060 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-27Objective-C doesn't consider the use of incomplete types as methodDouglas Gregor
parameter types to be ill-formed. However, it relies on the completeness of method parameter types when producing metadata, e.g., for a protocol, leading IR generating to crash in such cases.
