PMINUQ

Computes the minimum of two unsigned 64-bit integers and stores the result in the destination operand.

The following table covers what the source and destinations can be:

DO NOT support LOCK

This instruction is available only in 64-bit mode. It is NOT supported in compatibility mode.

The destination operand SHALL NOT be the same as the source operand for memory-to-memory operations, as the instruction requires a register or memory source and a register or memory destination according to the XMM/SSE specification; however, standard PMINUQ operates on XMM registers. If utilizing the PMINUQ mnemonic for general-purpose registers (via extensions), ensure the operands are u64.

The instruction operates on 128-bit XMM registers, processing two u64 elements in parallel (SIMD). Failure to align memory operands to 16-byte boundaries MAY result in performance degradation or general protection faults depending on the alignment check flags.
