...the reduction itself and outside of the loop. In your example you have for () *a = a++; … the “*a=“ part being a true use in the loop. This is a problem because at that point you would have to reduce the vectorized reduction. I.e if we wrote “a" as (pointer reduction, VF=2) as: %a_red = phi <2 x i32*> [preheader, <%a, 0>], [loop, %a_red_next] %a_red_next = gep %a_red, <3, 3> you would have to compute the value of “a” for the loop on every iteration from the vectorized reduction. %a_red = phi <2 x i32*> [preheader, <%a, 0>], [loop, %a_red_n...

Hi, We've got a fairly simple samba setup (no ldap/winbind etc) and until recently everything worked fine (using samba-2.2.5). But after switching to samba-2.2.6 w2k-clients fail to run the netlogon-scripts. When i look at the client it says: logonserver=\\<workstationname> BTW. The output of "nmblookup -S CPB" (to me) seems to say that CPB is the logonserver. querying CPB
