Hi

I'm wondering why FreeBSD has to simulate branches when the faulting
instruction is in the branch delay slot.
I'm curious about MipsEmulateBranch function, which is defined in
http://bxr.su/FreeBSD/sys/mips/mips/trap.c#MipsEmulateBranch

Why can't you just restart execution from the branch instruction?
