Yes, that is the same case for the x86/x86-64. All taken branches are 
trapped, so the trap handler needs to look at the instruction to 
determine whether it is a call, ret, or regular branch.

What does the ppc MSR[BE] do with the branch instructions used for 
implementing the atomic operations? Want to make sure that the atomic 
operations work correctly.
