[llvm-dev] MBB reordering vs. MBB fall-through

[Dr. ERDI Gergo via llvm-dev]

Hi,

Is it valid for an MBB to not have a final unconditional jump if the jump 
would be to the next MBB anyway? If yes, how is that supposed to interact 
with MBB reordering?

I'm asking because I've encountered a problem with the AVR backend where 
an MBB falls through to the wrong MBB due to reordering, and I'd like to 
know if the problem is having fall-throughs in the first place, or not 
communicating their presence somehow with other parts of LLVM.

Thanks,
 	Gergo
