From 7edd9ddc979f112287ff5184590830c67ea991bf Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Wed, 26 Feb 2014 23:39:46 +0000 Subject: tests/test-int128: Don't use __noclone__ attribute on clang clang doesn't support the __noclone__ attribute and emits a warning about it. Fortunately clang also implements a mechanism for asking if a particular attribute is implemented; use it. We assume that if the compiler doesn't support __has_attribute() then it must be GCC and must support __noclone__.
