Remove apply_val_pretty_printer parameter valaddr
This patch removes the parameter valaddr of extension_language_ops::apply_val_pretty_printer and remove const from "struct value *val". valaddr can be got in each extension language's implementation of apply_val_pretty_printer. gdb: 2016-11-11 Yao Qi <yao.qi@linaro.org> * cp-valprint.c (cp_print_value): Remove local base_valaddr. * extension-priv.h (struct extension_language_ops) <apply_val_pretty_printer>: Remove the second parameter. Remove const from "struct value *". Callers updated. * extension.c (apply_ext_lang_val_pretty_printer): Update comments. Remove parameter valaddr. Remove const from "struct value *". * extension.h (apply_ext_lang_val_pretty_printer): Update declaration. * guile/guile-internal.h (gdbscm_apply_val_pretty_printer): Update declaration. * guile/scm-pretty-print.c (gdbscm_apply_val_pretty_printer): Remove parameter valaddr. Remove const from "struct value *". * python/py-prettyprint.c (gdbpy_apply_val_pretty_printer): Likewise. * python/python-internal.h (gdbpy_apply_val_pretty_printer): Update declaration.
