Review an Instruction: MSR

I’m still working my way alphabetically (ususally) through the instruction set, picking instructions you should learn. We are in the M’s and there’s a plethora of multiply instructions we can review. I’m also selecting instructions I haven’t already covered. Today’s instruction is Multiply Single Register (MSR), which provides an easy way to multiply two single-precision register values without much setup. The result should be single-precision if you want to use this instruction. Read about MSG here.
