I recently committed several GMP assembly functions for powerpc32 using Altivec registers and instructions. I also reinstalled my system (a Pegasos2) recently, from an obsolete snapshot I got from somebody on the net, to a much less obsolete system. With the new assembly code *and* with the new

i was wrong, i misread the first question, and he told me, GMP is in userspace. by kernel handling of the SIMD regs he meant the switch from one userspace task to another, i think. what do you mean by in a limited context? Can you use SIMD in kernel code regs if you avoid preemtion? joerg On
