MIIsInTerminatorSequence()

static bool MIIsInTerminatorSequence ( const MachineInstr &  MI )

static

Given that the input MI is before a partial terminator sequence TSeq, return true if M + TSeq also a partial terminator sequence.

A Terminator sequence is a sequence of MachineInstrs which at this point in lowering copy vregs into physical registers, which are then passed into terminator instructors so we can satisfy ABI constraints. A partial terminator sequence is an improper subset of a terminator sequence (i.e. it may be the whole terminator sequence).
