Testing the plugin

This plugin is used by rasm2 and r2. You can verify that the plugin is properly loaded with this command:

  1. $ rasm2 -L | grep mycpu
  2. _d  mycpu        My CPU disassembler  (LGPL3)

Let’s open an empty file using the ‘mycpu’ arch and write some random code there.

  1. $ r2 -
  2.  -- I endians swap
  3. [0x00000000]> e asm.arch=mycpu
  4. [0x00000000]> woR
  5. [0x00000000]> pd 10
  6.            0x00000000    888e         mov r8, 14
  7.            0x00000002    b2a5         ifnot r10, r5
  8.            0x00000004    3f67         ret
  9.            0x00000006    7ef6         bl r15, r6
  10.            0x00000008    2701         xor r0, 1
  11.            0x0000000a    9826         mov r2, 6
  12.            0x0000000c    478d         xor r8, 13
  13.            0x0000000e    6b6b         store r6, 11
  14.            0x00000010    1382         add r8, r2
  15.            0x00000012    7f15         ret

Yay! it works.. and the mandatory oneliner too!

  1. r2 -nqamycpu -cwoR -cpd' 10' -
