Introduce gdb.FinishBreakpoint in Python
* Makefile.in (SUBDIR_PYTHON_OBS): Add py-finishbreakpoint.o. (SUBDIR_PYTHON_SRCS): Add python/py-finishbreakpoint.c. Add build rule for this file. * infcmd.c (print_return_value): Split to create get_return_value. (get_return_value): New function based on print_return_value. Handle case where stop_registers are not set. * inferior.h (get_return_value): New prototype. * python/py-breakpoint.c (bppy_pending_object): Make non-static. (gdbpy_breakpoint_created): Set is_py_finish_bp is necessary. (struct breakpoint_object): Move to python-internal.h (BPPY_REQUIRE_VALID): Likewise. (BPPY_SET_REQUIRE_VALID): Likewise. (gdbpy_breakpoint_created): Initialize is_finish_bp. (gdbpy_should_stop): Add pre/post hooks before/after calling stop method. * python/python-internal.h (breakpoint_object_type): Add as extern. (bppy_pending_object): Likewise. (typedef struct breakpoint_object) Removed. (struct breakpoint_object): Moved from py-breakpoint.c. Add field is_finish_bp. (BPPY_REQUIRE_VALID): Moved from py-breakpoint.c. (BPPY_SET_REQUIRE_VALID): Likewise. (frame_object_to_frame_info): New prototype. (gdbpy_initialize_finishbreakpoints): New prototype. (bpfinishpy_is_finish_bp): Likewise. (bpfinishpy_pre_stop_hook): Likewise. (bpfinishpy_post_stop_hook): Likewise. * python/py-finishbreakpoint.c: New file. * python/py-frame.c(frame_object_to_frame_info): Make non-static and accept PyObject instead of frame_object. (frapy_is_valid): Don't cast to frame_object. (frapy_name): Likewise. (frapy_type): Likewise. (frapy_unwind_stop_reason): Likewise. (frapy_pc): Likewise. (frapy_block): Likewise. (frapy_function): Likewise. (frapy_older): Likewise. (frapy_newer): Likewise. (frapy_find_sal): Likewise. (frapy_read_var): Likewise. (frapy_select): Likewise. * python/python.c (gdbpy_is_stopped_at_finish_bp): New noop function. (_initialize_python): Add gdbpy_initialize_finishbreakpoints. * python/python.h: Include breakpoint.h (gdbpy_is_stopped_at_finish_bp): New prototype. doc/ * gdb.texinfo (Finish Breakpoints in Python): New subsection. (Python API): Add menu entry for Finish Breakpoints. testsuite/ * Makefile.in (EXECUTABLES): Add py-finish-breakpoint and py-finish-breakpoint2 (MISCALLANEOUS): Add py-events-shlib.so and py-events-shlib-nodebug.so * gdb.python/py-breakpoint.exp (mult_line): Define and use variable instead of line number. * gdb.python/py-finish-breakpoint.c: New file. * gdb.python/py-finish-breakpoint.exp: New file. * gdb.python/py-finish-breakpoint.py: New file. * gdb.python/py-finish-breakpoint2.cc: New file. * gdb.python/py-finish-breakpoint2.exp: New file. * gdb.python/py-finish-breakpoint2.py: New file.
