From 8913cd95b2f815687f356574fde35179d292cbd1 Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Mon, 16 Nov 2015 13:51:01 +0000 Subject: [PATCH] configure.ac: test for the same atomic function as the one we use Unlikely that we'll hit a case where __sync_fetch_and_add is present while __sync_add_and_fetch isn't. Regardless let's keep things sane and consistent.
