Subject: Use scoped_value_mark in value_print
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ce3acbe9fa876647649cc88f94264a5c56bf46a1;p=binutils-gdb.git

Use scoped_value_mark in value_print

Switching the low-level printing to use the value API means we will be
using more temporary values.  This adds a scoped_value_mark to
value_print, so that these intermediates are destroyed in a timely
way.
