The start of some work on getting -mno-mmx working the way we want it to.

llvm-svn: 134300

Make clang behave in a gcc-compatible way in the presence of multiple flags for the same x86 target feature (e.g. -mno-sse -msse).  gcc uses a somewhat unintuitive algorithm here in that the enabled SSE instructions is based on the order of the *last* flag for *each* feature-level, so that "-mno-sse -msse2" only enables SSE2, but "-mno-sse -msse2 -msse" enables all SSE levels.

Issue reported on cfe-dev.

-Remove unnecessary 'return'.
-Remove unnecessary 'if' check (llvm_unreachable make sure attrStr will be non-null)
-Add a test of transferring ownership to a reference cast type.

cast type has no ownership specified, implicitly "transfer" the ownership of the cast'ed type
to the cast type:

cast type has no ownership specified, implicitly "transfer" the ownership of the cast'ed type

int f(int x) {
  if (int foo = f(bar)) {}
  return 0;
}

Clang produces the following error messages:

paren_imbalance.cc:2:19: error: use of undeclared identifier 'bar'
  if (int foo = f(bar)) {}
                  ^
paren_imbalance.cc:2:26: error: expected ')'
  if (int foo = f(bar)) {}
                        ^
paren_imbalance.cc:2:6: note: to match this '('
  if (int foo = f(bar)) {}
     ^

The second error is incorrect.  This patch will stop Clang from producing an error on parenthesis imbalance during error recovery when there isn't one.

Fix for PR7410. Allow functions in a derived class that improperly overwrite a virtual function in the base class to be inserted into the derived class function list to prevent extra errors every time the derived class is used.

llvm-svn: 134251

Fix AST representations of alias-declarations which define tag types. Inside classes, the tag types need to have an associated access specifier, and inside function definitions, they need to be included in the declarations of the DeclStmt. These issues manifested as assertions during template instantiation, and also in a WIP constexpr patch.

llvm-svn: 134250

This is kindof questionable but seems to do more-or-less the right thing.
This is not a particularly friendly part of the ABI.

llvm-svn: 134227

type/expression/template argument/etc. is instantiation-dependent if
it somehow involves a template parameter, even if it doesn't meet the
requirements for the more common kinds of dependence (dependent type,
type-dependent expression, value-dependent expression).

When we see an instantiation-dependent type, we know we always need to
perform substitution into that instantiation-dependent type. This
keeps us from short-circuiting evaluation in places where we
shouldn't, and lets us properly implement C++0x [temp.type]p2.

In theory, this would also allow us to properly mangle
instantiation-dependent-but-not-dependent decltype types per the
Itanium C++ ABI, but we aren't quite there because we still mangle
based on the canonical type in cases like, e.g.,

  template<unsigned> struct A { };
  template<typename T>
    void f(A<sizeof(sizeof(decltype(T() + T())))>) { }
  template void f<int>(A<sizeof(sizeof(int))>);

and therefore get the wrong answer.

llvm-svn: 134225

that serve as the base template name of an unresolved-name to
be mangled as a substitution.
