Re: rv(64) address space size


attached at my comments.

like everything else, performance is always a function of the implementation. same ISA, different implementation, different performance.

there are several themes to this thread.

1. do nothing for rv57 (keep INTEL)
2. add a some trivial stuff to rv57 (va translation) - NOTE the comment on what ARM has done
3. do something better for rv64 (currently intel has no rv64)

clearly the application space needs to be considered to answer the above themes.

having done this too many times, my philosophy is to make a system call as efficient as a subroutine call/return. and make pointer dereferencing as secure as we can make it.

Trojan Horse Pointers are EVIL.

have a happy and safe thanksgiving
