Although the PIC origins go back into the 1970s, it does not mean that newer CPUs
have better opcodes...

The MAC-instructions of the PPC: About 40 in all combinations from halfword/word,
(un)signed, (un)saturated, overflow en/disabled and so on. So it should be clear
what the difference between "maclhwsuo" and "machhwso" is...

PS:Ah, wait, I've forgot another 20 "negative MAC" variants like nmachhwso:
"Negative Multiply Accumulate High Halfword to Word Saturate Signed with Overflow"
