Example 1. Object File memcpy32.asm

            .global C_MEMCPY      
C_MEMCPY: .asmfunc stack_usage(12)

      CMP   r2, #0                  ; CHECK FOR n == 0
      BXEQ  lr                ;
      STMFD sp!, {r0, lr}           ; SAVE RETURN VALUE AND ADDRESS
      TST   r1, #0x3          ; CHECK ADDRESS ALIGNMENT
      BNE   _unaln                  ; IF NOT WORD ALIGNED, HANDLE SPECIALLY
      TST   r0, #0x3          ;
      BNE   _saln             ;

_aln: CMP   r2, #16                 ; CHECK FOR n >= 16
      BCC   _l16              ;
      STMFD sp!, {r4}         ;
      SUB   r2, r2, #16       ;

As shown in Example 2, the disassembler can produce disassembly from the object file, memcpy32.obj. The first two lines are entered on the command line.
