For the following code: Type * type = IntegerType::getInt32Ty(getGlobalContext()); IRBuilder<> builder(BB); std::set<Value *> Vset; Value * Vresult=0; for(std::set<Value*>::iterator Vit=Vset.begin();Vit!=Vset.end();Vit++) { Vresult=builder.CreateOr(Vit, Vresult, "WaitOr"); } Vset is inserted in previous loop by 0 or 1 The error is error: no matching member function for call to 'CreateOr' Vresult=builder.CreateOr(Vit, Vresult, "WaitOr"); Which input is wrong in the CreateOr() ? -- * R...

...lds to handle this kind of pattern be a welcome enhancement? I don't know if it's possible to make the matchers handle this case without adding a new matcher. Eg: // ((~A & B) | A) -> (A | B) if (match(Op0, m_c_And(m_Not(m_Specific(Op1)), m_Value(A)))) return BinaryOperator::CreateOr(A, Op1); Is there a way to make "m_Not(m_Specific())" match an inverted compare?
