Rd:
Compares two double 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.
