How to shift bits in a 2-5 byte long bytes object in python?

NettetIn the bit shift version the key instruction is shll $2, %eax which is a shift left logical - there's the divide, and everything else is just moving values around. In the divide version, you can see the idivl %r8d - but just above that is a cltd (convert long to double) and some additional logic around the spill and reload. Nettet25. feb. 2024 · First of all if it is int - and it is unsigned you can be sure that all the left shifted bits are 0 -'s.
