mr 4,11
mr 3,10
Actually, I'd swap the two mr instructions to never
have an instruction that uses the result from the
previous one.
Bad GCC. No biscuit.
Should we file a PR?
This is scheduled just fine. Every pair of instructions here can
execute together (on most CPUs, if not all); all instructions after
it are dependent on previous instructions. There also is no issue
(group) restriction that makes this scheduling suboptimal afaics.
