Line 309 in 94bf7a3

r0, r1, r2 = line.op_str.split(", ")

In qdb/utils.py::handle_bnj_arm(),

elif line.mnemonic == "add":
        r0, r1, r2 = line.op_str.split(", ")

the disassembly line parsing for the instruction

add pc, pc, r2, lsl #2.

fails with a too many values to unpack (expected 3) error.

To reproduce, use the opcode b'\x02\xf1\x8f\xe0' and run a single-step using do_step()

First of all, thanks for using qdb. Second, this occurred due to un-handled logical bits shifting, PR #1044 should be a fix for this.
