Subject: [PATCH 07/12] builtin: add predefines for __ATOMIC_RELAXED & friends
Date: Sun, 18 Oct 2020 00:56:28 +0200
Message-ID: <20201017225633.53274-8-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20201017225633.53274-1-luc.vanoostenryck@gmail.com>

The __atomic_*() builtins take an int argument to specify the
desired memory ordering. The different admissible values are
predefined by the compiler, so do that too for Sparse.
