non-386 atomic_load_acq(). %eax is an input since its value is used in the cmpxchg instruction, but we don't care what value it is, so setting it to a specific value is just wasteful. Thus, it is being used without being initialized as the warning stated, but it is ok for it to be used because its value isn't important. Thus, we are only sort of lying when we say it is an output only operand. - Add "cc" to the clobber list for atomic_load_acq() since the cmpxchgl changes ZF. |
