Should be faster since they explicitly bypass the MMU and don't take TLB
miss traps. However, the current scheme using gcc macros is not optimal
since gcc can't do as good a job at scheduling the instructions. The best
solution would be to modify gcc so pointers could be explicitly assocated
with ASIs.
you mean something like
void *foo __attribute__((__ASIXXX___));
? telling the compiler to generate all instructions with foo with
the appropriate ASI ? hmm... shouldn't be too hard to do ?
