- ylk1 7y agoGreat article as usual! Nice analysis. btw, just wondering, were you a processor architect in your previous roles?
- BeeOnRope 7y agoNo, my training and background is on the software side and so the hardware stuff is only a hobby.
- fluffything 7y agoIs zeroing a mask register a common operation? I'd suspect that setting all mask bits would be much more common. I mean, if you are going to zero the register, the real optimization would be to completely skip emitting any instructions for the operation you are going to perform, since it probably isn't going to do anything if the mask is cleared.
