Hi folks,
I noticed that with 3.x release that the GDB options (-S -s) for certain CPU 
results in very weird stepping.Usually stops afer a few steps, whilst the stub 
continues responding the PC doesnt update, however, I have only deeply looked 
at the m68k.
In the case of the m68K the SR gets the trace bit set (T=10b), and the PC 
doesnt update.The m68k gdbstub, and main gdbstub seem mostly unchanged.But it 
seems the INSN handling has changed greatly for the m68k.
Does anyone have any ideas what happened?
