[lldb-dev] Disassembling issue

Hi everyone,

I'm trying to have lldb being able to debug my architecture. It does it
well after loading my elf. But then I run it, stop it in middle, try to
disassemble and at that point it seems that I lost some information about
my architecture. lldb tries to disassemble it for x86, which in not
possible with my toolchain.

Here is a log of what I am doing:

(lldb) file test
Current executable set to 'test' (dpu).
(lldb) dis -s 0x80000000
test[0x80000000] <+0>:  jnz    id, 0x80000020
test[0x80000008] <+8>:  move   r0, 0xff
test[0x80000010] <+16>: release r0, 0x0, nz, 0x80000018
test[0x80000018] <+24>: sub    r0, r0, 0x1, pl, 0x80000010
(lldb) r
Process 21312 launched: '/home/rjodin/work/dpu_tools/llvm/lldb/test/test'
Process 21312 stopped
* thread #1, name = 'DPUthread0', stop reason = Thread stopped
    frame #0: 0x0000000080000090
(lldb) dis -s 0x80000000
error: Unable to find Disassembler plug-in for the 'x86_64' architecture.

Any ideas of what I am missing in my implementation?
