As I remember it, a taken branch acts as a stop whereas a non-taken branch doesn't (so if no explicit stop bit is following a branch, then it must be OK for the entire group to be executed in parallel). I suppose it's possible the definition changed or that my (admittedly bad) memory is playing tricks on me. ;-)

Hello, in the definition of the BRL_COND_FSYS_BUBBLE_DOWN macro in arch/ia64/kernel/gate.S, shouldn't there be a stop bit after the brl.cond instruction? According to the Intel specs, the current definition (which has no stop bit) triggers undefined behavior.
