Given a register of 4 bytes (or 16 for SIMD), there has to be an efficient way to sort the bytes in-register with a few instructions.
Thanks in advance.

Look up an efficient sorting network for N = the number of bytes you care about (4 or 16). Convert that to a sequence of compare and exchange instructions. (For N=16 that’ll be more than ‘a few’, though.)
