From 3d98c46092341c1373d960d0a66ca502d5b7ee7f Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Fri, 20 Mar 2020 03:55:17 -0700 Subject: plugin: Don't invoke LTO-wrapper Don't invoke LTO-wrapper since the LTO wrapper approach is not only slow but also unreliable. For GCC 10 or newer, LDPT_ADD_SYMBOLS_V2 will be used. bfd/ * configure.ac (HAVE_EXECUTABLE_SUFFIX): Removed. (EXECUTABLE_SUFFIX): Likewise. * config.in: Regenerated. * configure: Likewise. * plugin.c (bfd_plugin_close_and_cleanup): Defined as _bfd_generic_close_and_cleanup.
