+Subject: [PATCH 08/54] [Patch, microblaze]: Fix atomic side effects. In
+ atomic_compare_and_swapsi, add side effects to prevent incorrect assumptions
+ during optimization. Previously, the outputs were considered unused; this
+ generated assembly code with undefined side effects after invocation of the
+ atomic.
