    [XTENSA] Remove non-rt signal handling · 29c4dfd9
    Chris Zankel authored
    The non-rt signal handling was never really used, so we don't break
    anything. This patch also cleans up the signal stack-frame to make
    it independent from the processor configuration. It also improves
    the method used for controlling single-stepping. We now save and
    restore the 'icountlevel' register that controls single stepping
    and set or clear the saved state to enable or disable it.
