--- Comment #8 from Oleg Endo <olegendo at gcc dot gnu.org> 2012-10-01 13:49:44 UTC --- Hm, we still have libgcc/config/sh/linux-atomic.S around, which provides gUSA only implementations of atomic functions. How about replacing this with a C implementation instead? The C functions would then simply invoke the __builtin atomic functions. Would that be OK to do?
