LDR r0, = 0x7E0C0A2B ; MOV wont work

MOV r1, #0 ;r1 = 0

MOV r2,r0 ; r2 = r0

MOV r4, #0 ; r4 = 0

countone ; loop

MOVS r2, r2, LSR #1

CLZ r3, r2

ADD r1,r1,r4 ; Now Add carry bit

CMP r3, #0

BNE stop ; if r3 not equal to 0, then LSB is 0, dont perform ADD as adding 0 doesn't make sense

ADD r1, r1, #1 ; if r3 is set to 0 then LSB is 1,add 1 to r1

CMP r2, #0 ; compare r2 and 0

BNE countone ; branch if not equal to loop

stop B stop

END
