git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155082 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-14Add an AttributedStmt type to represent a statement with C++11 attributesRichard Smith
attached. Since we do not support any attributes which appertain to a statement (yet), testing of this is necessarily quite minimal. Patch by Alexander Kornienko! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154723 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-10Remove BlockDeclRefExpr and introduce a bit on DeclRefExpr toJohn McCall
track whether the referenced declaration comes from an enclosing local context. I'm amenable to suggestions about the exact meaning of this bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152491 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-07AST representation for user-defined literals, plus just enough of semanticRichard Smith
analysis to make the AST representation testable. They are represented by a new UserDefinedLiteral AST node, which is a sugared CallExpr. All semantic properties, including full CodeGen support, are achieved for free by this representation. UserDefinedLiterals can never be dependent, so no custom instantiation behavior is required. They are mangled as if they were direct calls to the underlying literal operator. This matches g++'s apparent behavior (but not its actual mangling, which is broken for literal-operator-ids). User-defined *string* literals are now fully-operational, but the semantic analysis is quite hacky and needs more work. No other forms of user-defined literal are created yet, but the AST support for them is present. This patch committed after midnight because we had already hit the quota for new kinds of literal yesterday. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152211 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-06Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,Ted Kremenek
NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features. Docs are forthcoming to document the implementation and behavior of these features. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152137 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-24Implement a new type trait __is_trivially_constructible(T, Args...)Douglas Gregor
that provides the behavior of the C++11 library trait std::is_trivially_constructible<T, Args...>, which can't be implemented purely as a library. Since __is_trivially_constructible can have zero or more arguments, I needed to add Yet Another Type Trait Expression Class, this one handling arbitrary arguments. The next step will be to migrate UnaryTypeTrait and BinaryTypeTrait over to this new, more general TypeTrait class. Fixes the Clang side of <rdar://problem/10895483> / PR12038. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151352 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-14Implement AST (de-)serialization for lambda expressions.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150491 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-27Reimplement (de-)serialization of Objective-C categories to eliminateDouglas Gregor
the direct serialization of the linked-list structure. Instead, use a scheme similar to how we handle redeclarations, with redeclaration lists on the side. This addresses several issues: - In cases involving mixing and matching of many categories across many modules, the linked-list structure would not be consistent across different modules, and categories would get lost. - If a module is loaded after the class definition and its other categories have already been loaded, we wouldn't see any categories in the newly-loaded module. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149112 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-17Delay the creation of the built-in Objective-C class 'Protocol' byDouglas Gregor
moving it from a "special type" to a predefined declaration, as we do for id, Class, and SEL. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148313 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-15Completely re-implement (de-)serialization of redeclarationDouglas Gregor
chains, again. The prior implementation was very linked-list oriented, and the list-splicing logic was both fairly convoluted (when loading from multiple modules) and failed to preserve a reasonable ordering for the redeclaration chains. This new implementation uses a simpler strategy, where we store the ordered redeclaration chains in an array-like structure (indexed based on the first declaration), and use that ordering to add individual deserialized declarations to the end of the existing chain. That way, the chain mimics the ordering from its modules, and a bug somewhere is far less likely to result in a broken linked list. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148222 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-01Eliminate ObjCForwardProtocolDecl, which is redundant now thatDouglas Gregor
ObjCProtocolDecl modules forward declarations properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147415 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-31Implement support for module requirements, which indicate the languageDouglas Gregor
features needed for a particular module to be available. This allows mixed-language modules, where certain headers only work under some language variants (e.g., in C++, std.tuple might only be available in C++11 mode). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147387 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-27Eliminate ObjCClassDecl, which is redundant now that ObjCInterfaceDeclDouglas Gregor
covers both declarations (@class) and definitions (@interface) of an Objective-C class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147299 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-22Serialize the AST reader's mapping from canonical declarations to theDouglas Gregor
set of (previously-canonical) declaration IDs to the module file, so that future AST reader instances that load the module know which declarations are merged. This is important in the fairly tricky case where a declaration of an entity, e.g., @class X; occurs before the import of a module that also declares that entity. We merge the declarations, and record the fact that the declaration of X loaded from the module was merged into the (now canonical) declaration of X that we parsed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147181 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-19Eliminate the first->last redeclaration map from the AST fileDouglas Gregor
format. It's no longer being used, now that we have a new implementation of redeclaration chains. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146905 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-17Completely re-implement (de-)serialization of declarationDouglas Gregor
chains. The previous implementation relied heavily on the declaration chain being stored as a (circular) linked list on disk, as it is in memory. However, when deserializing from multiple modules, the different chains could get mixed up, leading to broken declaration chains. The new solution keeps track of the first and last declarations in the chain for each module file. When we load a declaration, we search all of the module files for redeclarations of that declaration, then splice together all of the lists into a coherent whole (along with any redeclarations that were actually parsed). As a drive-by fix, (de-)serialize the redeclaration chains of TypedefNameDecls, which had somehow gotten missed previously. Add a test of this serialization. This new scheme creates a redeclaration table that is fairly large in the PCH file (on the order of 400k for Cocoa.h's 12MB PCH file). The table is mmap'd in and searched via a binary search, but it's still quite large. A future tweak will eliminate entries for declarations that have no redeclarations anywhere, and should drastically reduce the size of this table. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146841 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-08Implement umbrella directories for modules, which are similar toDouglas Gregor
umbrella headers in the sense that all of the headers within that directory (and eventually its subdirectories) are considered to be part of the module with that umbrella directory. However, unlike umbrella headers, which are expected to include all of the headers within their subdirectories, Clang will automatically include all of the headers it finds in the named subdirectory. The intent here is to allow a module map to trivially turn a subdirectory into a module, where the module's structure can mimic the directory structure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146165 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-05When writing a module file, keep track of the set of (sub)modules thatDouglas Gregor
it imports, establishing dependencies at the (sub)module granularity. This is not a user-visible change (yet). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145808 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-03Implement support for precompiled headers, preambles, and serializedDouglas Gregor
"main" files that import modules. When loading any of these kinds of AST files, we make the modules that were imported visible into the translation unit that loaded the PCH file or preamble. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145737 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-02Introduce a module import declaration, so that we properly represent, e.g.,Douglas Gregor
__import_module__ std.vector; in the AST. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145725 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-02Implement (de-)serialization of the set of exported modules in aDouglas Gregor
module map. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145695 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-01Switch the ID numbers used for submodule IDs in the AST reader over toDouglas Gregor
a standard global/local scheme, so that submodule definitions will eventually be able to refer to submodules in other top-level modules. We'll need this functionality soonish. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145549 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-30Implement (de-)serialization of the description of a module and itsDouglas Gregor
submodules. This information will eventually be used for name hiding when dealing with submodules. For now, we only use it to ensure that the module "key" returned when loading a module will always be a module (rather than occasionally being a FileEntry). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145497 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-16Implement (de-)serialization of the buffer contents for an overriddenDouglas Gregor
file in the source manager. This allows us to properly create and use modules described by module map files without umbrella headers (or with incompletely umbrella headers). More generally, we can actually build a PCH file that makes use of file -> buffer remappings, which could be useful in libclang in the future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144830 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-06Change the AST representation of operations on Objective-CJohn McCall
property references to use a new PseudoObjectExpr expression which pairs a syntactic form of the expression with a set of semantic expressions implementing it. This should significantly reduce the complexity required elsewhere in the compiler to deal with these kinds of expressions (e.g. IR generation's special l-value kind, the static analyzer's Message abstraction), at the lower cost of specifically dealing with the odd AST structure of these expressions. It should also greatly simplify efforts to implement similar language features in the future, most notably Managed C++'s properties and indexed properties. Most of the effort here is in dealing with the various clients of the AST. I've gone ahead and simplified the ObjC rewriter's use of properties; other clients, like IR-gen and the static analyzer, have all the old complexity *and* all the new complexity, at least temporarily. Many thanks to Ted for writing and advising on the necessary changes to the static analyzer. I've xfailed a small diagnostics regression in the static analyzer at Ted's request. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143867 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-28[PCH] Keep track of file-level declarations that are contained by files.Argyrios Kyrtzidis
Introduce a FILE_SORTED_DECLS [de]serialization record that contains a file sorted array of file-level DeclIDs in a PCH/Module. The rationale is to allow "targeted" deserialization of decls inside a range of a source file. Cocoa PCH increased by 0.8% Difference of creation time for Cocoa PCH is below the noise level. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143238 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-27[PCH] Pull the location out of the serialized declarations and put it in the ↵Argyrios Kyrtzidis
array of decl bit offsets. This allows us to easily get at the location of a decl without deserializing it. It increases size of Cocoa PCH by only 0.2%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143123 91177308-0d34-0410-b5e6-96231b3b80d8

r142914: "Introduce a placeholder type for "pseudo object"" r142915: "Pull the pseudo-object stuff into its own file." git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142921 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25Introduce a placeholder type for "pseudo object"John McCall
expressions: expressions which refer to a logical rather than a physical l-value, where the logical object is actually accessed via custom getter/setter code. A subsequent patch will generalize the AST for these so that arbitrary "implementing" sub-expressions can be provided. Right now the only client is ObjC properties, but this should be generalizable to similar language features, e.g. Managed C++'s __property methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142914 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25Implement support for dependent Microsoft __if_exists/__if_not_existsDouglas Gregor
statements. As noted in the documentation for the AST node, the semantics of __if_exists/__if_not_exists are somewhat different from the way Visual C++ implements them, because our parsed-template representation can't accommodate VC++ semantics without serious contortions. Hopefully this implementation is "good enough". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142901 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-21[PCH] When serializing Stmts, keep track of when sub statements are ↵Argyrios Kyrtzidis
referenced again and in such a case just write out a reference of a previously serialized Stmt, instead of serializing it all over again. This saves memory + space + [de]serializing time, and avoids blowing up memory with pathological cases. rdar://10293911 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142696 91177308-0d34-0410-b5e6-96231b3b80d8

committed at the moment to help support C++0x <atomic>, but it should be a solid base for implementing the full specification of C1x _Atomic. Thanks to Jeffrey Yasskin for the thorough review! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141330 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19Introduce PreprocessingRecord::getPreprocessedEntitiesInRange()Argyrios Kyrtzidis
which will do a binary search and return a pair of iterators for preprocessed entities in the given source range. Source ranges of preprocessed entities are stored twice currently in the PCH/Module file but this will be fixed in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140058 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-15[PCH] Overhaul how preprocessed entities are [de]serialized.Argyrios Kyrtzidis
-Use an array of offsets for all preprocessed entities -Get rid of the separate array of offsets for just macro definitions; for references to macro definitions use an index inside the preprocessed entities array. -Deserialize each preprocessed entity lazily, at first request; not in bulk. Paves the way for binary searching of preprocessed entities that will offer efficiency and will simplify things on the libclang side a lot. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139809 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
2011-09-01Support importing of ObjC categories from modules.Argyrios Kyrtzidis
The initial incentive was to fix a crash when PCH chaining categories to an interface, but the fix was done in the "modules way" that I hear is popular with the kids these days. Each module stores the local chain of categories and we combine them when the interface is loaded. We also warn if non-dependent modules introduce duplicate named categories. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138926 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-17In the AST file format, eliminate the CHAINED_METADATA record. Instead,Douglas Gregor
all AST files have a normal METADATA record that has the same form regardless of whether we refer to a chained PCH or any other kind of AST file. Introduce the IMPORTS record, which describes all of the AST files that are imported by this AST file, and how (as a module, a PCH file, etc.). Currently, we emit at most one entry to this record, to support chained PCH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137869 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

2011-08-12Move 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
2011-08-12In the serialized AST format, make the translation unit a "predefined"Douglas Gregor
declaration that never actually gets serialized. Instead, serialize the various kinds of update records (lexical decls, visible decls, the addition of an anonymous namespace) for the translation unit, even if we're not chaining. This way, we won't have to deal with multiple loaded translation unit declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137395 91177308-0d34-0410-b5e6-96231b3b80d8
