Subject: Introduce generic_value_print_ptr
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2a5b130bcb6f376b6a28d8378172ed3f9b92e9d9;p=binutils-gdb.git

Introduce generic_value_print_ptr

This introduces generic_value_print_ptr, a value-based analogue of
generic_val_print_ptr, and changes generic_value_print to use it.

gdb/ChangeLog
2020-03-13  Tom Tromey  <tom@tromey.com>

	* valprint.c (generic_value_print): Call generic_value_print_ptr.
	* valprint.c (generic_value_print_ptr): New function.
