<div>Hi,</div><div><br></div><div>I was playing with the Constant::getAllOnesValue() method and found that it doesn't handles</div><div>PointerTypes correctly. When receiving a "i32*" argument, it was returning with </div><div>some big integer vector, such as <12113216 x i32>.</div><div><br></div><div>When you call this method passing a PointerType, the following code is executed:</div><div><br></div><div>00152 VectorType *VTy = cast<VectorType>(Ty);</div><div>00153 return ConstantVector::getSplat(VTy->getNumElements(),</div><div>00154 getAllOnesValue(VTy->getElementType()</div><div><br></div><div>When VTy->getNumElements() is called, it returns the value of the instance variable NumElements</div><div>present in VectorType objects, but we passed in a PointerType (SequentialType), which doesn't have</div><div>this variable but have at the same position one variable representing the type of the pointed thing.</div><div><br></div><div>00309 class SequentialType : public CompositeType {</div><div>00310 Type *ContainedType; </div><div><br></div><div>So getNumElements() will return some part of the value of ContainedType (an address), which</div><div>explains that big integer vectors.</div><div><br></div><div>Do you think this is an expected behaviour or a bug?</div><div><br></div><div>Regards,</div><div>Gabriel</div><div><br></div> </div></body>
