Most methods of Bool currently rely on the last bit, but
CAS
generates the int value to match
old
based on the user's inputand so it assumes the value is either
1
or0
.The only reason we relid on the last bit is that
Toggle
wasimplemented using an atomic add. We can instead implement
Toggle
using a loop aroundCAS
.Fixes #61.
