I need to multiply a*17 without using the multiply instructions in ARM assembly language. I

Error from ARM-assembly instruction 'MULS' with constant. the MUL instruction is very dangerous because ARM architecture does not consider the signed or unsigned for MUL. The explanation shows that just lower 32 bit value of multiplication is stored into the destination register. Therefore the result of each signed or unsigned multiplication is the same., Operation The MUL instruction multiplies the values from Rn and Rm, and places the least significant 32 bits of the result in Rd. Register restrictions Rn must be different from Rd in architectures before ARMv6. You cannot use PC for any register. You can use SP in ARM instructions but this is deprecated in ARMv6T2 and above..
