2010-08-18Generate Attr subclasses with TableGen.Sean Hunt
Now all classes derived from Attr are generated from TableGen. Additionally, Attr* is no longer its own linked list; SmallVectors or Attr* are used. The accompanying LLVM commit contains the updates to TableGen necessary for this. Some other notes about newly-generated attribute classes: - The constructor arguments are a SourceLocation and a Context&, followed by the attributes arguments in the order that they were defined in Attr.td - Every argument in Attr.td has an appropriate accessor named getFoo, and there are sometimes a few extra ones (such as to get the length of a variadic argument). Additionally, specific_attr_iterator has been introduced, which will iterate over an AttrVec, but only over attributes of a certain type. It can be accessed through either Decl::specific_attr_begin/end or the global functions of the same name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111455 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-11Speculatively revert r110610 " Make ObjCInterfaceDecl redeclarable,Douglas Gregor

2010-08-09- Make ObjCInterfaceDecl redeclarable, and create separate decl nodes for ↵Sebastian Redl
forward declarations and the definition. - Eagerly create ObjCInterfaceTypes for declarations. - The two above changes lead to a 0.5% increase in memory use and no speed regression when parsing Cocoa.h. On the other hand, now chained PCH works when there's a forward declaration in one PCH and the interface definition in another. - Add HandleInterestingDecl to ASTConsumer. PCHReader passes the "interesting" decls it finds to this function instead of HandleTopLevelDecl. The default implementation forwards to HandleTopLevelDecl, but ASTUnit's handler for example ignores them. This fixes a potential crash when lazy loading of PCH data would cause ASTUnit's "top level" declaration collection to change while being iterated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110610 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-29Merge PCHWriterDecl.cpp's isRequiredDecl and ↵Argyrios Kyrtzidis
CodeGenModule::MayDeferGeneration into a new function, DeclIsRequiredFunctionOrFileScopedVar. This is essentially a CodeGen predicate that is also needed by the PCH mechanism to determine whether a decl needs to be deserialized during PCH loading for codegen purposes. Since this logic is shared by CodeGen and the PCH mechanism, move it to the ASTContext, thus CodeGenModule's GetLinkageForFunction/GetLinkageForVariable and the GVALinkage enum is moved out of CodeGen. This fixes current (and avoids future) codegen-from-PCH bugs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109784 91177308-0d34-0410-b5e6-96231b3b80d8

by PCHReader. Currently, adding it to visible decls of a PCH'ed translation unit has no effect because adding visible decls before deserialization has no effect (the decls won't be visible).

2010-07-03Lazily declare default constructors. We now delay the construction ofDouglas Gregor
declarations for implicit default constructors, copy constructors, copy assignment operators, and destructors. On a "simple" translation unit that includes a bunch of C++ standard library headers, we generate relatively few of these implicit declarations now: 4/159 implicit default constructors created 18/236 implicit copy constructors created 70/241 implicit copy assignment operators created 0/173 implicit destructors created And, on this translation unit, this optimization doesn't really provide any benefit. I'll do some more performance measurements soon, but this completes the implementation work for <rdar://problem/8151045>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107551 91177308-0d34-0410-b5e6-96231b3b80d8

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
2010-06-09Tweak our handling of the notion of a standard conversion sequenceDouglas Gregor
being a subsequence of another standard conversion sequence. Instead of requiring exact type equality for the second conversion step, require type *similarity*, which is type equality with cv-qualifiers removed at all levels. This appears to match the behavior of EDG and VC++ (albeit not GCC), and feels more intuitive. Big thanks to John for the line of reasoning that supports this change: since cv-qualifiers are orthogonal to the second conversion step, we should ignore them in the type comparison. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105678 91177308-0d34-0410-b5e6-96231b3b80d8
