Subject: Use gdb_bfd_ref_ptr in target_bfd
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ade72a3453670d518ba14fe47bc7a64df81ce766;p=binutils-gdb.git

Use gdb_bfd_ref_ptr in target_bfd

I noticed that target_bfd was using manual reference counting for the
BFD it held.  This patch changes it to use gdb_bfd_ref_ptr instead.

Tested by the buildbot.
