alt Hacker NewsFair enough, I've only really ever found assembly level optimization on embedded microcontrollers to make any degree of sense. Performance optimization usually means something along the lines of "convince co-workers not to implement their own bubble sort" in my lines of work
Yeah, I've also come across a lot of assembly code which was faster 10 years ago, but where the compiler now beats it. So for a while now my take has been to mostly avoid asm, but if needed always have a compiled version, and always do runtime performance detection to select optimal version.
