> If the count is actually zero, we can end up doing x << 0 (a left shift of > zero). Does hppa handle this correctly? Does it, for The hardware doesn't support a left shift of zero, so at the moment the expanders and patterns require that the shift length be greater than zero. I recently fixed a bug in this area. Should copies be generated for this case? Dave -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31169
