STSMIN, STSMINL Atomic signed minimum on word or doubleword in memory, without return This instruction atomically loads a 32-bit word or 64-bit doubleword from memory, compares it against the value held in a register, and stores the smaller value back to memory, treating the values as signed numbers. STSMIN does not have release semantics. STSMINL stores to memory with release semantics, as described in Load-Acquire, Store-Release. For information about addressing modes, see Load/Store addressing modes. If PSTATE.DIT is 1, the timing of this instruction is insensitive to the value of the data being loaded or stored.
