How to create a 64 bit ConstInt having a value of -1?
I tried the following:
- ConstantInt::get(Type::getInt64Ty(Ctx), APInt(0xFFFFFFFFFFFFFFFF, 64,
false))
- ConstantInt::get(Type::getInt64Ty(Ctx), APInt(-1, 64))
I am receiving the following error: Assertion `NumBits <= MAX_INT_BITS &&
"bitwidth too large" failed

Thanks & Regards,
Dipanjan

How to achieve this?
Thx
