◆ canFallThrough()
| bool MachineBasicBlock::canFallThrough | ( | ) |
Return true if the block can implicitly transfer control to the block after it by falling off the end of it.
This should return false if it can reach the block after it, but it uses an explicit branch to do so (e.g., a table jump). True is a conservative answer.

Various pieces of code can cause excess edges in the CFG to be inserted.
If we have proven that MBB can only branch to DestA and DestB, remove any other MBB successors from the CFG. DestA and DestB can be null. Besides DestA and DestB, retain other edges leading to LandingPads (currently there can be only one; we don't check or require that here). Note it is possible that DestA and/or DestB are LandingPads.

| void MachineBasicBlock::transferSuccessors | ( | MachineBasicBlock * | FromMBB | ) |
Transfers all the successors from MBB to this machine basic block (i.e., copies all the successors FromMBB and remove all the successors from FromMBB).

◆ transferSuccessorsAndUpdatePHIs()
| void MachineBasicBlock::transferSuccessorsAndUpdatePHIs | ( | MachineBasicBlock * | FromMBB | ) |
Transfers all the successors, as in transferSuccessors, and update PHI operands in the successor blocks which refer to FromMBB to refer to this.

◆ updateTerminator()
| void MachineBasicBlock::updateTerminator | ( | ) |
Update the terminator instructions in block to account for changes to the layout.
If the block previously used a fallthrough, it may now need a branch, and if it previously used branching it may now be able to use a fallthrough.

◆ validateSuccProbs()
| void MachineBasicBlock::validateSuccProbs | ( | ) | const |
Validate successors' probabilities and check if the sum of them is approximate one.
This only works in DEBUG mode.
