Extended Description

While attempting to compile as much of my entire freebsd system with clang, as I could, compiling graphics/opencv-core with it core dumps every time.

Here is a link to the appropriate persistence file:

http://www.thesouthernlibertarian.com/llvm.tgz

And on IRC I was told this:

lib/CodeGen/CGBuiltin.cpp:86: clang::CodeGen::RValue EmitBinaryAtomic(clang::CodeGen::CodeGenFunction&, llvm::AtomicRMWInst::BinOp, const clang::CallExpr*): Assertion `CGF.getContext().hasSameUnqualifiedType(T, E->getArg(0)->getType()->getPointeeType())' failed.
include that in the PR
and that it applies to both 3.0 and ToT

[efriedma-quic]

Reduced testcase:
template struct Ptr {
void f();
};
template inline void Ptr<_Tp>::f() {
int* _refcount;
__sync_fetch_and_add(_refcount, 1);
}
void f(Ptr *a) { a->f(); }

Yet another atomic builtin template instantiation bug.

Fixed in Clang r145248.
