[PATCH for-6.1 v4 09/15] hw/core: Introduce TCGCPUOps.debug_check_breakpoint

Posted by Richard Henderson 4 years, 6 months ago

New hook to return true when an architectural breakpoint is
to be recognized and false when it should be suppressed.

First use must wait until other pieces are in place.
