Write a program that counts the number of bits equal to one in r1, and stores the result in r2. for example, if r1=x0a0c, then r2=x0004 after the program runs. to receive credit, you can only modify the contents of r1 and r2, and no other register, and your solution should have no more than 9 lines of code.

MOV R1, $0A0C    ;

  MOV R2, #0 ;

L1 : MOV R1, R1, LSL #1 ;

  ADC R2, R2, #1 ;

  CMP R1, #0 ;

  BNE L1    ;
