+
+We don't target this yet, and some llvm versions incorrectly enable it based
+on cpu string, causing crashes.
+(Albeit this is a losing battle, it is pretty much guaranteed when the next
+new feature comes along llvm will mistakenly enable it on some future cpu,
+thus we would have to proactively disable all new features as llvm adds them.)
+
+This should fix https://bugs.freedesktop.org/show_bug.cgi?id=94291 (untested)
