Your jargon and majority of asm constraint wordage in the GCC manual remains unclear for me. I'm just a GCC user, which wants to use new CPU instructions with old compiler version. I have no any intention to modify GCC by myself. Understood. In that case I think your only option is to use local register variables to put your variables in specific registers, and write your asm that way. http://gcc.gnu.org/onlinedocs/gcc/Local-Reg-Vars.html Ian
