which produces really bad code. This could be done in instcombine, but it's
probably better to do it in the front-end instead.

They are actually grammatically considered definitions and parsed
accordingly.

This fixes the outstanding bugs regarding defaulting functions after
their declarations.

We now really nicely diagnose the following construct (try it!)

int foo() = delete, bar;

Still todo: Defaulted functions other than default constructors
            Test cases (including for the above construct)

llvm-svn: 131228

defaulted default constructors.

As it happens, making sure that we handle out-of-line defaulted
functions properly will involved making sure that we actually parse them
correctly, so that's coming after.

llvm-svn: 131224

We still don't parse out-of-line defaults correctly, which is needed to
get the full effect out of this patch.

Fix PR9902: correctly substitute alias templates within the template in which they are defined: provide an empty list of arguments for each containing template context during substitution.

llvm-svn: 131211

argument deduction failures. Only implemented in C++0x, since this is
a significant change in behavior from C++98/03.

nested of an out-of-line declaration, only require a 'template<>'
header for each enclosing class template that hasn't been previously
specialized; previously, we were requiring 'template<>' for enclosing
class templates and members of class templates that hadn't been
previously specialized. Fixes <rdar://problem/9422013>.

This means we get C++0x jump-across-intializer semantics correct.

In Microsoft mode, allow conversion from pointer to integral type no matter what size the integral type is. Necessary to parse MFC code.

void f(char *ptr) {
  char var = (char)ptr;

then teach -Wreturn-type to handle the same.  Net effect:  we now correctly

that they are C++0x extensions, and put them in the appropriate
group. We already support most of the semantics. Addresses
<rdar://problem/9407525>.

llvm-svn: 131153

Wait, what?

So, we run Clang (and LLVM) tests in an environment where the md5sum of the
input files becomes a component of the path. When testing the preprocessor,
the path becomes part of the output (in line directives). In this test, we
were grepping for the absence of "abc" in the output. When the stars aligned
properly, the md5sum component of the path contained "abc" and the test
failed. Oops.

I've edited one diagnostic which would print "copy constructor" for copy
constructors and "constructor" for any other constructor. If anyone is
extremely enamored with this, it can be reinstated with a simple boolean
flag rather than calling getSpecialMember, which is inappropriate.
