示例1: RemoveBranch
unsigned WebAssemblyInstrInfo::RemoveBranch(MachineBasicBlock &MBB) const {
MachineBasicBlock::instr_iterator I = MBB.instr_end();
unsigned Count = 0;
while (I != MBB.instr_begin()) {
--I;
if (I->isDebugValue())
continue;
if (!I->isTerminator())
break;
// Remove the branch.
I->eraseFromParent();
I = MBB.instr_end();
++Count;
}
return Count;
}
示例2: ReplaceUsesOfBlockWith
/// ReplaceUsesOfBlockWith - Given a machine basic block that branched to
/// 'Old', change the code and CFG so that it branches to 'New' instead.
void MachineBasicBlock::ReplaceUsesOfBlockWith(MachineBasicBlock *Old,
MachineBasicBlock *New) {
assert(Old != New && "Cannot replace self with self!");
MachineBasicBlock::instr_iterator I = instr_end();
while (I != instr_begin()) {
--I;
if (!I->isTerminator()) break;
// Scan the operands of this machine instruction, replacing any uses of Old
// with New.
for (unsigned i = 0, e = I->getNumOperands(); i != e; ++i)
if (I->getOperand(i).isMBB() &&
I->getOperand(i).getMBB() == Old)
I->getOperand(i).setMBB(New);
}
// Update the successor information.
replaceSuccessor(Old, New);
}
