<pre>1.
lvm/lib/CodeGen/MachinePipeliner.cpp:963]: (style) Condition
'Phi.getOperand(i+1).getMBB()==Loop' is always true
Source code is
for (unsigned i = 1, e = Phi.getNumOperands(); i != e; i += 2)
if (Phi.getOperand(i + 1).getMBB() != Loop)
InitVal = Phi.getOperand(i).getReg();
else if (Phi.getOperand(i + 1).getMBB() == Loop)
LoopVal = Phi.getOperand(i).getReg();
Suggest new code
for (unsigned i = 1, e = Phi.getNumOperands(); i != e; i += 2)
if (Phi.getOperand(i + 1).getMBB() != Loop)
InitVal = Phi.getOperand(i).getReg();
else
LoopVal = Phi.getOperand(i).getReg();</pre>
