From 06333fea767dc1eaf88ac286293fcbaa0ef2de9e Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Fri, 11 May 2018 12:36:19 -0600 Subject: Make "cbfd" a gdb_bfd_ref_ptr This changes program_space::cbfd to be a gdb_bfd_ref_ptr. This makes it somewhat less error-prone to use, because now it manages the reference counting automatically. Tested by the buildbot. 2018-05-16 Tom Tromey * gdbcore.h (core_bfd): Redefine. * corelow.c (core_target::close): Update.
