2010-02-11Clean up ownership of 'AttributeList' objects in Parser. ApparentlyTed Kremenek
we would just leak them all over the place, with no clear ownership of these objects at all. AttributeList objects would get leaked on both error and non-error paths. Note: I introduced the usage of llvm::OwningPtr<AttributeList> to manage these objects, which is particularly useful for methods with multiple return sites. In at least one method I used them even when they weren't strictly necessary because it clarified the ownership semantics and made the code easier to read. Should the excessive 'take()' and 'reset()' calls become a performance issue we can always re-evaluate. Note+1: I believe I have not introduced any double-frees, but it would be nice for someone to review this. This fixes <rdar://problem/7635046>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95847 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-10Improve code completion by introducing patterns for the various C andDouglas Gregor
C++ grammatical constructs that show up in top-level (namespace-level) declarations, member declarations, template declarations, statements, expressions, conditions, etc. For example, we now provide a pattern for static_cast<type>(expr) when we can have an expression, or using namespace identifier; when we can have a using directive. Also, improves the results of code completion at the beginning of a top-level declaration. Previously, we would see value names (function names, global variables, etc.); now we see types, namespace names, etc., but no values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93134 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-25Eliminate CXXConditionDeclExpr with extreme prejudice.Douglas Gregor
All statements that involve conditions can now hold on to a separate condition declaration (a VarDecl), and will use a DeclRefExpr referring to that VarDecl for the condition expression. ForStmts now have such a VarDecl (I'd missed those in previous commits). Also, since this change reworks the Action interface for if/while/switch/for, use FullExprArg for the full expressions in those expressions, to ensure that we're emitting Note that we are (still) not generating the right cleanups for condition variables in for statements. That will be a follow-on commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89817 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-28Get rid of some useless uses of NoExtensions. The philosophy here is Eli Friedman
that if we're going to print an extension warning anyway, there's no point to changing behavior based on NoExtensions: it will only make error recovery worse. Note that this doesn't cause any behavior change because NoExtensions isn't used by the current front-end. I'm still considering what to do about the remaining use of NoExtensions in IdentifierTable.cpp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70273 91177308-0d34-0410-b5e6-96231b3b80d8

For something like this: $ cat t2.c #define bool int void f(int x, int y) { bool b = !x && y; } We used to produce: $ clang-cc t2.c -ast-dump typedef char *__builtin_va_list; void f(int x, int y) (CompoundStmt 0x2201f10 <t2.c:3:22, line:5:1> (DeclStmt 0x2201ef0 <line:2:14> <---- 0x2201a20 "int b = (BinaryOperator 0x2201ed0 <line:4:10, col:16> 'int' '&&' (UnaryOperator 0x2201e90 <col:10, col:11> 'int' prefix '!'

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
