Yes locals are given to the cpu
Angel: Don't worry about that. If you have too many of them, they will end in the second level cache and then in the regular RAM, its not like in ASM where it must reside in CPU. Beside that: Don't think you will fill up 512kbyte that easy ;-) (thats the minimum actual have like AMD64 - AMD does not need them that much their connection too ram beats Intel to death - and goes up to 2MB of second level cache)
