gdb/ 2009-03-05 Tom Tromey <tromey@redhat.com> Add support for convenience functions in Python. * Makefile.in (SUBDIR_PYTHON_OBS): Add python-function.o. (SUBDIR_PYTHON_SRCS): Add python-function.c. (python-function.o): New target. * eval.c: Include "python/python.h" and <ctype.h>. (evaluate_subexp_standard): Handle values of type TYPE_CODE_INTERNAL_FUNCTION. * gdbtypes.h (type_code): Add TYPE_CODE_INTERNAL_FUNCTION. * parse.c (write_exp_string): Remove duplicate word in comment. * python/python-function.c: New file. * python/python-internal.h (gdbpy_initialize_functions): Add prototype. * python/python.c (_initialize_python): Call gdbpy_initialize_functions. * valprint.c (value_check_printable): Handle values of type TYPE_CODE_INTERNAL_FUNCTION. * value.c: Include "cli/cli-decode.h". (internal_function): New struct. (functionlist, internal_fn_type): New static variables. (lookup_only_internalvar, lookup_internalvar): Add const qualifier to name argument. (create_internalvar): Likewise. Initialize new field. (set_internal_var): Fix typo in comment. Don't allow assignment to canonical variable. (value_create_internal_function, value_internal_function_name, call_internal_function, function_command, function_destroyer, add_internal_function): New functions. (_initialize_values): Create `function' placeholder command. Initialize internal_fn_type. * value.h (lookup_only_internalvar, create_internalvar, lookup_internalvar): Add const qualifier to name argument. (internal_function_fn, add_internal_function, call_internal_function, value_internal_function_name): Add prototypes. (struct internalvar) <canonical>: New field. gdb/doc/ 2008-03-05 Tom Tromey <tromey@redhat.com> * gdb.texinfo (Convenience Vars): Document convenience functions. (Functions In Python): New node. (Python API): Update. gdb/testsuite/ 2009-03-05 Thiago Jung Bauermann <bauerman@br.ibm.com> * gdb.python/python-function.exp: New file.
