Hello,
I'd like to propose that the GDB remote protocol be extended to support
a cycle step command. This command would be used when either
interacting with physical control devices such as JTAG or (more often)
cycle accurate simulators.
Possible syntaxes include:
QCycle=<NR>
and i<NR>
comments suggestions additional data people thing may be needed. Unlike
the ``S'' and ``C'' commands I've not included an address. Changing the
address in a cycle accurate model can get very complex.
Exactly what a cycle is would be target dependant.
Andrew
