Good point well made but can you explain why changing a B to a BE in a tight
loop results in 43% difference?
But aren't those two completely different cases (even if it is the same
instruction)? The first is an unconditional branch, the second one a
conditional branch. That probably makes a big difference to the processor.
Where I expect the unconditional one to be faster than the conditional one.
I assume it is 43% faster than the conditional one? If it is the other way
around I will be very surprised as well.
No. It's the opposite which is why I originally posted. The
unconditional branch is slower and I want to know why.
Fred!
