First: we don't have any rotate vtables or opcodes. Shall these be considered as a TODO? > ...

And that as well as the above int rotate seems to make these operations rather arbitrary. What about: rotl Pdest, Psrc, 32 # rotate left by 1 32-bitwise rotr Pdest, Psrc, 64 # rotate right by 1 64-bitwise, expand if needed or/and: rotl Pdest, Psrc, n, 32 # rotate left by n 32-bitwise rotl Pdest, n, 32 # rotate left in place by n 32-bitwise leo
