From 6ba7f5cccd68b2f014c5a6b71cbc39e045a3d14d Mon Sep 17 00:00:00 2001 From: Ben Pfaff Date: Mon, 15 Jul 2013 14:14:05 -0700 Subject: [PATCH] test-atomic: Re-enable atomic read-write-modify tests. This reverts commit 05d299e0ccca80736cd4438c3224540c5448a7d4 (test-atomic: Drop atomic read-modify-write tests for the moment.) because the test for detecting whether GCC support atomic operation built-ins has been fixed.
