llvm::Type::isSingleValueType. Currently these two functions have
the same behavior, but soon isFirstClassType will return true for
struct and array types.
Clang may some day want to use of isFirstClassType for some of
these some day as an optimization, but it'll require some
consideration.

tracked object to "escape": it's reference count might be incremented by the
called function, thus causing an object's lifetime to extend beyond when the
local reference count is decremented to 0.

actually work (instead of crashing llc), and there's enough info emitted
to get line number information in gdb. This should hopefully be helpful
for debugging non-working programs.
I got rid of the begin/endregion calls because the implementation wasn't
working; someone who knows the debugging info a bit better might try to
add it. I really have no clue how a compiler is supposed to emit them.
This commit shouldn't have any effect without -g.

lib/CodeGen/CGExpr.cpp and to change include/clang/AST/Attr.h to
use its own enum for visibility types instead of using
llvm::GlobalValue::VisibilityTypes. These changes eliminate
dependencies in the AST library on LLVM's VMCore library.

in Sema, per discussion on mailing list. This doesn't cause any changes
in the test results. I'll probably add some more tests at some point,
but it's an open question what we need to accept to be compatible with
real code.
This doesn't touch the existing isConstantExpr method on Expr; that
should be addressed somehow eventually (either removed or refined to
whatever is appropriate).

consensus was that it was fine; iso646 is trivial.
We actually don't need that many headers overall... on Ubuntu, at least,
all we need are stdint.h, stdarg.h, limits.h, and float.h to stop
depending on having gcc's headers around for normal code.
On a side note, the path searching needs some improvement; I had to
hardcode the path to my header directory into clang.cpp to get the
driver to use it consistently.

as far as I can tell, and it fixes code like test/CodeGen/functions.c.
(Whatever performance effect it might have, crashing on a
construct like this isn't really acceptable; I've run into this
multiple times.)

extend beyond the end of the function.
I'm not completely sure this is the right way to fix this bug, so
someone familiar with the parser should double-check.

Fixed a bug in ParmVarDecl::param_end(): Handle the case where there are no
ParmVarDecls for a FunctionDecl, but its function prototype has formal arguments
(can happen with typedefs).

1) Sema::ParseAST now constructs a TranslationUnit object to own the top-level Decls, which releases the top-level Decls upon exiting ParseAST.
2) Bug fix: TranslationUnit::~TranslationUnit handles the case where a Decl is added more than once as a top-level Decl.
3) Decl::Destroy is now a virtual method, obviating the need for a special dispatch based on DeclKind.
3) FunctionDecl::Destroy now releases its Body using its Destroy method.
4) Added Stmt::Destroy and Stmt::DestroyChildren, which recursively delete the child ASTs of a Stmt and call their dstors. We may need to special case dstor/Destroy methods for particular Stmt subclasses that own other dynamically allocated objects besides AST nodes.
5) REGRESSION: We temporarily are not deallocating attributes; a FIXME is provided.
