--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
There is code in the driver to disable adding `-z now -z relro` but it looks
like it is not working for some reason:
if (!any_link_options_p && !static_p)
{
#if defined HAVE_LD_PIE && defined LD_PIE_SPEC
save_switch (LD_PIE_SPEC, 0, NULL, /*validated=*/true,
/*known=*/false);
#endif
/* These are passed straight down to collect2 so we have to break
it up like this. */
if (HAVE_LD_NOW_SUPPORT)
{
add_infile ("-z", "*");
add_infile ("now", "*");
}
if (HAVE_LD_RELRO_SUPPORT)
{
add_infile ("-z", "*");
add_infile ("relro", "*");
}
}
Oh any_link_options_p just means -r, -shared, -no-pie, -pie was passed. It
does not include -Wl, options.
