The Official Radare2 Book

Testing the plugin

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

$ rasm2 -L | grep mycpu

_d mycpu My CPU disassembler (LGPL3)

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

$ r2 -

-- I endians swap

[0x00000000]> e asm.arch=mycpu

[0x00000000]> woR

[0x00000000]> pd 10

0x00000000 888e mov r8, 14

0x00000002 b2a5 ifnot r10, r5

0x00000004 3f67 ret

0x00000006 7ef6 bl r15, r6

0x00000008 2701 xor r0, 1

0x0000000a 9826 mov r2, 6

0x0000000c 478d xor r8, 13

0x0000000e 6b6b store r6, 11

0x00000010 1382 add r8, r2

0x00000012 7f15 ret

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