Oh right correct we are inside the instruction and in a case we have very few arguments, and only 32-bit. If we allow the target to allocate scratch registers themselves, it's probably better to do that via a function. -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurel...@aurel32.net http://www.aurel32.net
