Shift 32-bit Integer Immediate
Shift 64-bit Integer Immediate
Compare Single Precision Floating Point
Shift a 32-bit integer by the count specified in the seven bit, two’s complement
immediate value. A positive number indicates a left shift and a negative
number indicates a right shift. This instruction may also be used to copy a 32-
bit integer from one register to another using a shift value of 0.

Shift[6:0]:
Compares two single precision floating point numbers and stores an integer
representing the result in the ARM920T register; the highest four bits of the
integer result match the N, Z, C, and V bits, respectively, in the ARM920T’s
program status register, while the bottom 28 bits are zeros. If Rd = 15, then the
four status bits are stored in the ARM status register, CPSR.
