Fix scripted probe breakpoints The documentation for make-breakpoint from the Guile API and the `spec' variant of the gdb.Breakpoint constructor from the Python API state that the format acceptable for location strings is the same as that accepted by the break command. However, using the -probe qualifier at the beginning of the location string causes a GDB internal error as it attempts to decode a probe location in the wrong code path. Without this functionality, there doesn't appear to be another way to set breakpoints on probe points from Python or Guile scripts. This patch introduces a new helper function that returns a breakpoint_ops instance appropriate for a parsed location and updates the Guile and Python bindings to use said function, rather than the current hard-coded use of bkpt_breakpoint_ops. Since this logic is duplicated in the handling of the `break' and `trace' commands, those are also updated to call into the new helper function. gdb/ChangeLog: 2019-12-10 George Barrett <bob@bob131.so> Fix scripted probe breakpoints. * breakpoint.c (tracepoint_probe_breakpoint_ops): Move declaration forward.
