NettetI tried an SSSE3 version to take advantage of PALIGNR instead of MOVSS + SHUFPS, but it wasn't as advantageous as I had hoped -- 10% faster on Core 2, but 7% slower on Atom. One reason is that PALIGNR is a shift instruction, so on Atom it still requires pipe 0, while MOVSS is a cheap instruction that can fit in a pipe 1 hole. NettetThe Cortex-M3 Instruction Set.

The lower 9 bits of the value are shifted left by 9 bits and replace the 9 bits occupied by the destination reference in the destination address. An example of how this code might be used is as follows: delivery winston salem food
