2010-06-29Support C++ friend declarations for PCH.Argyrios Kyrtzidis
This commit 'introduces' a slightly different way to restore the state of the AST object. It makes PCHDeclReader/PCHDeclWriter friends and gives them access to the private members of the object. The rationale is to avoid using/modifying the AST interfaces for PCH read/write so that to: -Avoid complications with objects that have side-effects during creation or when using some setters. -Not 'pollute' the AST interface with methods only used by the PCH reader/writer -Allow AST objects to be read-only. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107219 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-28Modify the way sub-statements are stored and retrieved from PCH.Argyrios Kyrtzidis
Before this commit, sub-stmts were stored as encountered and when they were placed in the Stmts stack we had to know what index each stmt operand has. This complicated supporting variable sub-stmts and sub-stmts that were contained in TypeSourceInfos, e.g. x = sizeof(int[1]); would crash PCH. Now, sub-stmts are stored in reverse order, from last to first, so that when reading them, in order to get the next sub-stmt we just need to pop the last stmt from the stack. This greatly simplified the way stmts are written and read (just use PCHWriter::AddStmt and PCHReader::ReadStmt accordingly) and allowed variable stmt operands and TypeSourceInfo exprs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107087 91177308-0d34-0410-b5e6-96231b3b80d8

As part of this, pull together trapv handling into the same enum. This also add support for NSW multiplies. This also makes PCH disagreement on overflow behavior silent, since it really doesn't matter except for warnings and codegen (no macros get defined etc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106956 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-16Implement first TD-based usage of attributes.Sean Hunt
Currently, there are two effective changes: - Attr::Kind has been changed to attr::Kind, in a separate namespace rather than the Attr class. This is because the enumerator needs to be visible to parse. - The class definitions for the C++0x attributes other than aligned are generated by TableGen. The specific classes generated by TableGen are controlled by an array in TableGen (see the accompanying commit to the LLVM repository). I will be expanding the amount of code generated as I develop the new attributes system while initially keeping it confined to these attributes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106172 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-11Split DependentNameType into two types. DependentNameType represents theJohn McCall
case of an elaborated-type-specifier like 'typename A<T>::foo', and DependentTemplateSpecializationType represents the case of an elaborated-type-specifier like 'typename A<T>::template B<T>'. The TypeLoc representation of a DependentTST conveniently exactly matches that of an ElaboratedType wrapping a TST. Kill off the explicit rebuild methods for RebuildInCurrentInstantiation; the standard implementations work fine because the nested name specifier is computable in the newly-entered context. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105801 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-15Substantially alter the design of the Objective C type AST by introducingJohn McCall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103870 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-27Make the InjectedClassNameType the canonical type of the current instantiationJohn McCall
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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102407 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-19Remove the capture, serialization, and deserialization of commentDouglas Gregor

2010-03-19Implement serialization and lazy deserialization of the preprocessingDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99002 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-16Fix header-search problems with precompiled headers, where theDouglas Gregor
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.

2010-03-10Create a new InjectedClassNameType to represent bare-word references to the John McCall
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.
