Curious to know... at which point did it become favourable to do a 32-byte align rather than a 16-byte align on x86 processors? Should the compiler start favouring 32-byte aligns for loops, say?


"11.3μop cache"

I couldn't find the 32byte align in that doc though. I must have picked that up elsewhere. (I think).
