If thats true, it seems like you could make a great optimization pass which chooses a code layout in order to make the program run faster. I wonder how predictable code layout is on performance across different CPUs.
Sounds like an interesting problem!
- nerpderp82 4y agoTotally agree, area is ripe for a lot of experimentation and data visualization. I think it would be fun to see what is the minimal amount of insertions or shifts in layout to get the most pathological decrease in performance. Could be a great vehicle to challenge performance assumptions we all have.
