ok, so if I understood the system, when SOFTWARE_SINGLE_STEP_P=1,
SOFTWARE_SINGLE_STEP is the function which emulates the singlestepping using
breakpoints.
but if I don't define SOFTWARE_SINGLE_STEP_P, or if I define it to 1, then
do I have to provide a specialized SOFTWARE_SINGLE_STEP_P() ? There is no
such thing in tm-arm.h.
