DescriptionPerform a division of and save quotient in and remainder in .
.text:00000EEE MOVS R0, R4 ; R0 = 0x7365 .text:00000EF0 LDR R1, [SP,#0x1BB8+current_prime_number] ; R1 = 0x2 .text:00000EF2 BL __aeabi_uidivmod ; division R0/R1. R0 = quotient = 0x39b2, R1 = remainder = 0x1 .text:00000EF6 LSLS R1, R1, #0x10 .text:00000EF8 LSRS R1, R1, #0x10 .text:00000EFA BNE loc_F5C
The above example could be illustrated as follows in python
>>> r0 = 0x7365 >>> r1 = 0x2 >>> (quotient, remainder) = (r0/r1, r0%r1) >>> hex(quotient) '0x39b2' >>> hex(remainder) '0x1'
