user: 提供的汇编代码用C语言表示会是什么样子:

```asm
<usage>:
  endbr64
  push   %rbp
  mov    %rsp,%rbp
  sub    $0x10,%rsp
  mov    %edi,-0x4(%rbp)
  lea    D4(%rip),%rax
  mov    %rax,%rdi
  call   <printf@plt>
  mov    -0x4(%rbp),%eax
  mov    %eax,%edi
  call   <exit@plt>
  nop
  leave
  ret

tool: D4: Usage: smd_pkt_loopback_test [OPTIONS] [PARAMS] [TEST_TYPE]...
Runs the loopback test with parameters specified
over a SMD PKT device.  /dev/smd_pkt_loopback will beused if a device is not specified

OPTIONS can be:
  -v, --verbose         run with debug messages on (NOTE:
                           currently has no effect).
  -h, --help            print this help message and exit
  -c, --nocheck         donot check the integrity of data
  -w, --blocking_write use blocking writes

PARAMS can be:
  -b, --bytes           write/read buffer size (default 2 bytes)
  -i, --iterations      number of test iterations (default 1)
  -p, --pattern         pattern to be written (default 0xfa)
  -d, --delay TIME      delay after iterations/2 by TIME seconds
  -f, --file            The character device to use (default
                           /dev/smd_pkt_loopback)

TEST_TYPE can be:
  -n, --nominal         run standard functionality tests
  -a, --adversarial     run tests that try to break the
                          driver, not supported currently
  -s, --stress          run tests that try to maximize the
                          capacity of the driver,
                          not supported currently
  -r, --repeatability   run 10 iterations of both the
                          nominal and adversarial tests,
                          not supported currently
