16  xb <addr> [<len>]
17        prints validity bits for <len> (or 1) bytes at <addr>
18            bit values 0 = valid, 1 = invalid, __ = unaddressable byte
19        Then prints the bytes values below the corresponding validity bits
20        in a layout similar to the gdb command 'x /<len>xb <addr>'
21        Example: xb 0x........ 10
22  get_vbits <addr> [<len>]
23        Similar to xb, but only prints the validity bytes by group of 4.

27  check_memory [addressable|defined] <addr> [<len>]
28        check that <len> (or 1) bytes at <addr> have the given accessibility
29            and outputs a description of <addr>
