//! # CASPT, CASPAT, CASPALT, CASPLT
//!
//! This instruction reads a pair of 64-bit doublewords from memory, and compares them against the values held in the first pair of registers. If the comparison is equal, the values in the second pair of registers are written to memory. If the comparison is not equal, the architecture permits writing the value read from the location to memory. If the writes are performed, the reads and writes occur atomically such that no other modification of the memory location can take place between the reads and writes.
