Hi,

I managed to run gdb "make check" on a real arm cortex-m3 board.
During this regression test, I saw many failures are caused by "Cannot
insert hardware breakpoint 8" and "You may have requested too many
hardware breakpoints/watchpoints". It's true that my arm board only
supports limited number breakpoints. So how to workaround this
limitation for regression test? Thanks.

BR,
Terry

You may want to turn these off:

set breakpoint auto-hw on/off
set can-use-hw-watchpoints 1/0
