--- Comment #36 from Alan Modra <amodra at gmail dot com> 2012-11-02 02:13:20 UTC --- The change I mention in #c22 http://gcc.gnu.org/viewcvs?view=revision&revision=184110 tests for atomic ops on all of bool, short, int and long long, where the previous test was for *either* atomic bool or atomic short. My fix for powerpc removed the long long test. Does mips lack atomic on bool or short?
