2009-04-25various "is invalid" cleanups for C++ ctors/dtors.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70021 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-25This is a pretty big cleanup for how invalid decl/type are handle.Chris Lattner
This gets rid of a bunch of random InvalidDecl bools in sema, changing us to use the following approach: 1. When analyzing a declspec or declarator, if an error is found, we set a bit in Declarator saying that it is invalid. 2. Once the Decl is created by sema, we immediately set the isInvalid bit on it from what is in the declarator. From this point on, sema consistently looks at and sets the bit on the decl. This gives a very clear separation of concerns and simplifies a bunch of code. In addition to this, this patch makes these changes: 1. it renames DeclSpec::getInvalidType() -> isInvalidType(). 2. various "merge" functions no longer return bools: they just set the invalid bit on the dest decl if invalid. 3. The ActOnTypedefDeclarator/ActOnFunctionDeclarator/ActOnVariableDeclarator methods now set invalid on the decl returned instead of returning an invalid bit byref. 4. In SemaType, refering to a typedef that was invalid now propagates the bit into the resultant type. Stuff declared with the invalid typedef will now be marked invalid. 5. Various methods like CheckVariableDeclaration now return void and set the invalid bit on the decl they check. There are a few minor changes to tests with this, but the only major bad result is test/SemaCXX/constructor-recovery.cpp. I'll take a look at this next. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70020 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-16Fix a crash bug when comparing overload quality of conversion operators with ↵Sebastian Redl
conversion constructors. Remove an atrocious amount of trailing whitespace in the overloaded operator mangler. Sorry, couldn't help myself. Change the DeclType parameter of Sema::CheckReferenceInit to be passed by value instead of reference. It wasn't changed anywhere. Let the parser handle C++'s irregular grammar around assignment-expression and conditional-expression. And finally, the reason for all this stuff: implement C++ semantics for the conditional operator. The implementation is complete except for determining lvalueness. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69299 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-12Parse deleted member functions. Parsing member declarations goes through a ↵Sebastian Redl
different code path that I forgot previously. Implement the rvalue reference overload dance for returning local objects. Returning a local object first tries to find a move constructor now. The error message when no move constructor is defined (or is not applicable) and the copy constructor is deleted is quite ugly, though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68902 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-29Push DeclGroup much farther throughout the compiler. Now the variousChris Lattner
productions (except the already broken ObjC cases like @class X,Y;) in the parser that can produce more than one Decl return a DeclGroup instead of a Decl, etc. This allows elimination of the Decl::NextDeclarator field, and exposes various clients that should look at all decls in a group, but which were only looking at one (such as the dumper, printer, etc). These have been fixed. Still TODO: 1) there are some FIXME's in the code about potentially using DeclGroup for better location info. 2) ParseObjCAtDirectives should return a DeclGroup due to @class etc. 3) I'm not sure what is going on with StmtIterator.cpp, or if it can be radically simplified now. 4) I put a truly horrible hack in ParseTemplate.cpp. I plan to bring up #3/4 on the mailing list, but don't plan to tackle #1/2 in the short term. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68002 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-28Introduce a new OpaquePtr<N> struct type, which is a simple POD wrapper for aChris Lattner
pointer. Its purpose in life is to be a glorified void*, but which does not implicitly convert to void* or other OpaquePtr's with a different UID. Introduce Action::DeclPtrTy which is a typedef for OpaquePtr<0>. Change the entire parser/sema interface to use DeclPtrTy instead of DeclTy*. This makes the C++ compiler enforce that these aren't convertible to other opaque types. We should also convert ExprTy, StmtTy, TypeTy, AttrTy, BaseTy, etc, but I don't plan to do that in the short term. The one outstanding known problem with this patch is that we lose the bitmangling optimization where ActionResult<DeclPtrTy> doesn't know how to bitmangle the success bit into the low bit of DeclPtrTy. I will rectify this with a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67952 91177308-0d34-0410-b5e6-96231b3b80d8
