[LLVMdev] get value

[Alexandru Ionut Diaconescu]

Hi Cristianno,

Thank you, it works :) 

with an extra cast:
                                    Value *v ......
                                    ConstantInt* RR = (ConstantInt *)v;
                                    uint64_t VV = (RR->getValue()).getLimitedValue();
                                    errs()<<"\nRR  "<<VV<<"\n";

Hi Alexandru,

if you have a Value pointer named v, you could use the method v->getValue().getLimitedValue(), which returns uint64_t, that can be casted as int.

Hope I could help,
