Function eikon3ds_core::arch::register_specified_shift::rotate_right

pub fn rotate_right(
    val: u32,
    shift_amount: u32,
    carry_flag: bool
) -> ShiftResults

Rotates bits right by a register specified amount.

Bits moved out of the right-hand end are rotated back into the left-hand end. If the shift amount is specified is zero, the carry-out is the old carry flag and val is untouched. Otherwise, the shift amount is repeatedly subtracted by 32 until its in the range of 1..=32. Once the shift amount is in range, if the shift amount is zero, this means the original shift amount was outside the range of an integer so the val is untouched and the carry out is bit 31 of val. If the shift amount is greater than zero, the shift functions identically as instruction_specified_shift::rotate_right using the newly in range shift amount.
