agreed on 64bit. Also this advise is old it hasn't popped up out of nowhere. I still recall it being crucial back in the early 2000's to improve performance. And today it remains very valid because of 32 bit IoT systems.
- rwmj 3y agoRight, on 32 bit you do want to omit frame pointers so %ebp can be used as a general register. (Fedora is on the verge of dropping 32 bit platforms entirely.)
