* Substantially alter the design of the Objective C type AST by introducingJohn McCall2010-05-151-13/+10
| | | | | | | | | | | | | | | | | | | | | ObjCObjectType, which is basically just a pair of one of {primitive-id, primitive-Class, user-defined @class} with a list of protocols. An ObjCObjectPointerType is therefore just a pointer which always points to one of these types (possibly sugared). ObjCInterfaceType is now just a kind of ObjCObjectType which happens to not carry any protocols. Alter a rather large number of use sites to use ObjCObjectType instead of ObjCInterfaceType. Store an ObjCInterfaceType as a pointer on the decl rather than hashing them in a FoldingSet. Remove some number of methods that are no longer used, at least after this patch. By simplifying ObjCObjectPointerType, we are now able to easily remove and apply pointers to Objective-C types, which is crucial for a certain kind of ObjC++ metaprogramming common in WebKit. llvm-svn: 103870

* Make the InjectedClassNameType the canonical type of the current instantiationJohn McCall2010-04-271-1/+2
| | | | | | | | | | | | | | | | of a class template or class template partial specialization. That is to say, in template <class T> class A { ... }; or template <class T> class B<const T*> { ... }; make 'A<T>' and 'B<const T*>' sugar for the corresponding InjectedClassNameType when written inside the appropriate context. This allows us to track the current instantiation appropriately even inside AST routines. It also allows us to compute a DeclContext for a type much more efficiently, at some extra cost every time we write a template specialization (which can be optimized, but I've left it simple in this patch). llvm-svn: 102407

* Remove the capture, serialization, and deserialization of commentDouglas Gregor2010-03-191-20/+0
| | | | | | | | ranges as part of the ASTContext. This code is not and was never used, but contributes ~250k to the size of the Cocoa.h precompiled header. llvm-svn: 99007
* Implement serialization and lazy deserialization of the preprocessingDouglas Gregor2010-03-191-3/+86
| | | | | | | | | | | | | | | | | | | | | | | | record (which includes all macro instantiations and definitions). As with all lay deserialization, this introduces a new external source (here, an external preprocessing record source) that loads all of the preprocessed entities prior to iterating over the entities. The preprocessing record is an optional part of the precompiled header that is disabled by default (enabled with -detailed-preprocessing-record). When the preprocessor given to the PCH writer has a preprocessing record, that record is written into the PCH file. When the PCH reader is given a PCH file that contains a preprocessing record, it will be lazily loaded (which, effectively, implicitly adds -detailed-preprocessing-record). This is the first case where we have sections of the precompiled header that are added/removed based on a compilation flag, which is unfortunate. However, this data consumes ~550k in the PCH file for Cocoa.h (out of ~9.9MB), and there is a non-trivial cost to gathering this detailed preprocessing information, so it's too expensive to turn on by default. In the future, we should investigate a better encoding of this information. llvm-svn: 99002
* Fix header-search problems with precompiled headers, where theDouglas Gregor2010-03-161-15/+15
| | | | | | | | | | | | | | | | | | | | | | presence or absence of header map arguments when using the precompiled header would cause Clang to get confused about which headers had already been included/imported, along with their controlling macros. The fundamental problem is that the serialization of the header search information was relying on the UIDs of FileEntry objects at PCH generation time and PCH load time to be equivalent, which effectively means that we had to probe the same files in the same order. Differing header map arguments caused an extra FileEntry lookup, but it's easy to imagine other minor command-line arguments triggering this problem. Header-search information is now encoded along with the source-location entry for a file, so that we register information about a file's properties as a header at the same time we create the FileEntry for that file. Fixes <rdar://problem/7743243>. llvm-svn: 98636

* Create a new InjectedClassNameType to represent bare-word references to the John McCall2010-03-101-0/+9
| | | | | | | | | | | | | injected class name of a class template or class template partial specialization. This is a non-canonical type; the canonical type is still a template specialization type. This becomes the TypeForDecl of the pattern declaration, which cleans up some amount of code (and complicates some other parts, but whatever). Fixes PR6326 and probably a few others, primarily by re-establishing a few invariants about TypeLoc sizes. llvm-svn: 98134

* Add VarDecl::isThisDeclarationADefinition(), which properly encapsulates the ↵Sebastian Redl2010-01-311-5/+3
| | | | | | logic for when a variable declaration is a (possibly tentativ) definition. Add a few functions building on this, and shift C tentative definition handling over to this new functionality. This shift also kills the Sema::TentativeDefinitions map and instead simply stores all declarations in the renamed list. The correct handling for multiple tentative definitions is instead shifted to the final walk of the list. llvm-svn: 94968
