- Instruction *InstCombiner::visitXor(BinaryOperator &I) {

- if (Op0I && Op1I && Op0I->isShift() &&
- Op0I->getOpcode() == Op1I->getOpcode() &&
- Op0I->getOperand(1) == Op1I->getOperand(1) &&
- (Op1I->hasOneUse() || Op1I->hasOneUse())) {
- ...
- }
- Most likely this is what should be written here: (Op0I->hasOneUse() || Op1I->hasOneUse()).
- This suspicious code was found in Clang project by PVS-Studio static code analyzer.
- Warning message is:
- V501 There are identical sub-expressions to the left and to the right of the '||' operator: Op1I->hasOneUse () || Op1I->hasOneUse () LLVMInstCombine instcombineandorxor.cpp 2246
