Subject: Fix crash with "maint print arc"
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=509e6230915a050d510a36ca9482193c76a6a216;p=binutils-gdb.git

Fix crash with "maint print arc"

Luis noticed that "maint print arc" would crash, because the command
handler did not find "show" in the command name, violating an
invariant.  This patch fixes the bug by changing the registration to
use add_basic_prefix_cmd instead.
