Function Documentation

static void classifyCondBranch ( MachineInstr *  I, MachineBasicBlock *&  TBB, SmallVectorImpl< MachineOperand > &  Cond  )

static

Takes apart a given conditional branch MachineInstr (see isCondBranch), setting TBB to the destination basic block and populating the Cond vector with data necessary to recreate the conditional branch at a later date. First element will be the opcode, and subsequent ones define the conditions being branched on in an instruction-specific manner.

static bool isCondBranch ( unsigned  Opc )

static

Does the Opcode represent a conditional branch that we can remove and re-add at the end of a basic block?
