The error is coming from source/Commands/CommandObjectDisassemble.cpp . It’s
not able to create the disassembler for your architecture. The call to
Disassembler::FindPlugin fails.
My guess is something in the call to MCDisasmInstance::Create in
source/Plugins/Disassembler/llvm/DisassemblerLLVMC.cpp is failing. Step through
that and make sure everything there is working.

Subject: [EXT] [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`__bootstrap:
test[0x80000000] <+0>: jnz id, 0x80000020
test[0x80000008] <+8>: move r0, 0xff

test[0x80000018] <+24>: sub r0, r0, 0x1, pl, 0x80000010
(lldb) r

(lldb) dis -s 0x80000000
error: Unable to find Disassembler plug-in for the 'x86_64' architecture.
(lldb)
Any ideas of what I am missing in my implementation?
Thanks,
