llvm dev - Apr 2021 - Successors of MBB

Hello All,
In my implementation of EmitInstrWithCustomInserter I have two branches in
machine basic block so this MBB has 3 successors (two from branches and one
fallthrough) but I've not found such a solution in other targets. I wonder
if there is any restriction for the number of successors for MBB?

There is no restriction.  For example, indirect branches can have multiple (more
than two) targets.
