[Lldb-commits] [PATCH] D16853: Use BKPT instead of UDF for arm/thumb breakpoints

GDB doesnt use bkpt instruction for user debugging for the reason that it interferes with jtag debug probes. I am not sure if LLDB will be ever used with a jtag probe in near future but still a jtag prob might be connected to the same hardware which is using LLDB to debug a user space application.

heres a discussion which happened some years back on similar issues:

I am fine with using bkpt as long as it helps us debug IT blocks and doesnt interfere with any of our currently functionality.
