hi all, from my experience, the __sync_compare_and_swap_16 functions have the signatures: __sync_compare_and_swap_16 (type *ptr, type oldval, type newval) that doesn't quite map to the CMPXCHG16B instruction, since the ptr argument is required to be 16 byte aligned ... i am not sure, but shouldn't the signature be something like: __sync_compare_and_swap_16 (type __attribute__ ((__aligned__(16))) *ptr, type oldval, type newval) ? (at least for the x86_64 architecture) thanks in advance, tim -- tim@xxxxxxxxxx http://tim.klingt.org The composer makes plans, music laughs. Morton Feldman
