AtomicRMWInst - an instruction that atomically reads a memory location, combines it with another value, and then stores the result back. Returns the old value.
Definition at line 556 of file Instructions.h.
This enumeration lists the possible modifications atomicrmw can make. In the descriptions, 'p' is the pointer to the instruction's memory location, 'old' is the initial value of *p, and 'v' is the other value passed to the instruction. These instructions always return 'old'.
