bool MachineBasicBlock::canFallThrough

(

)

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.

computeRegisterLiveness - Return whether (physical) register Reg has been <def>ined and not <kill>ed as of just before MI.

bool MachineBasicBlock::CorrectExtraCFGEdges	(	MachineBasicBlock *	DestA,

CorrectExtraCFGEdges - 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.

const

isLayoutSuccessor - Return true if the specified MBB will be emitted immediately after this block, such that if this block exits by falling through, control will transfer to the specified MBB. Note that MBB need not be a successor at all, for example if this block ends with an unconditional branch to some other block.
