Always deserialize from PCH file scoped variables with non trivial constructor/destructor. Fixes http://llvm.org/PR7692 llvm-svn: 109501 2010-07-27 20:56:10 +08:00			`// Header for PCH test cxx-required-decls.cpp`

Merge PCHWriterDecl.cpp's isRequiredDecl and 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. llvm-svn: 109784 2010-07-30 02:15:58 +08:00

Make sure C++ variable definitions are actually passed to the consumer when loaded from PCH. llvm-svn: 110322 2010-08-05 17:47:59 +08:00
