(SUBDIR_PYTHON_SRCS): Add py-unwind.c. (py-unwind.o): New recipe. * NEWS: mention Python frame unwinding. * data-directory/Makefile.in (PYTHON_FILE_LIST): Add gdb/unwinder.py and gdb/command/unwinder.py * python/lib/gdb/__init__.py (packages): Add frame_unwinders list. (execute_unwinders): New function. * python/lib/gdb/command/unwinders.py: New file. * python/lib/gdb/unwinder.py: New file. * python/py-objfile.c (objfile_object): Add frame_unwinders field. (objfpy_dealloc): Decrement frame_unwinders reference count. (objfpy_initialize): Create frame_unwinders list. (objfpy_get_frame_unwinders): New function. (objfpy_set_frame_unwinders): Ditto. (objfile_getset): Add frame_unwinders attribute to Objfile. * python/py-progspace.c (pspace_object): Add frame_unwinders field. (pspy_dealloc): Decrement frame_unwinders reference count. (pspy_initialize): Create frame_unwinders list. (pspy_get_frame_unwinders): New function. (pspy_set_frame_unwinders): Ditto. (pspy_getset): Add frame_unwinders attribute to gdb.Progspace. * python/py-unwind.c: New file. * python/python-internal.h (pspy_get_name_unwinders): New prototype. (objpy_get_frame_unwinders): New prototype. (gdbpy_initialize_unwind): New prototype. * python/python.c (gdbpy_apply_type_printers): Call gdbpy_initialize_unwind. gdb/doc/ChangeLog: * doc/python.texi (Writing a Frame Unwinder in Python): Add section. gdb/testsuite/ChangeLog: * gdb.python/py-unwind-maint.c: New file. * gdb.python/py-unwind-maint.exp: New test. * gdb.python/py-unwind-maint.py: New file. * gdb.python/py-unwind.c: New file. * gdb.python/py-unwind.exp: New test. * gdb.python/py-unwind.py: New test. --- gdb/python/python-internal.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'gdb/python/python-internal.h') diff --git a/gdb/python/python-internal.h b/gdb/python/python-internal.h index 4c4d32a..0581b33 100644 --- a/gdb/python/python-internal.h +++ b/gdb/python/python-internal.h @@ -391,12 +391,14 @@ PyObject *pspace_to_pspace_object (struct program_space *) CPYCHECKER_RETURNS_BORROWED_REF; PyObject *pspy_get_printers (PyObject *, void *); PyObject *pspy_get_frame_filters (PyObject *, void *); +PyObject *pspy_get_frame_unwinders (PyObject *, void *); PyObject *pspy_get_xmethods (PyObject *, void *); PyObject *objfile_to_objfile_object (struct objfile *) CPYCHECKER_RETURNS_BORROWED_REF; PyObject *objfpy_get_printers (PyObject *, void *); PyObject *objfpy_get_frame_filters (PyObject *, void *); +PyObject *objfpy_get_frame_unwinders (PyObject *, void *); PyObject *objfpy_get_xmethods (PyObject *, void *); PyObject *gdbpy_lookup_objfile (PyObject *self, PyObject *args, PyObject *kw); @@ -491,6 +493,8 @@ int gdbpy_initialize_arch (void) CPYCHECKER_NEGATIVE_RESULT_SETS_EXCEPTION; int gdbpy_initialize_xmethods (void) CPYCHECKER_NEGATIVE_RESULT_SETS_EXCEPTION; +int gdbpy_initialize_unwind (void) + CPYCHECKER_NEGATIVE_RESULT_SETS_EXCEPTION; struct cleanup *make_cleanup_py_decref (PyObject *py); struct cleanup *make_cleanup_py_xdecref (PyObject *py); -- cgit v1.1
