Here is the patch with slightly tweaked install.texi and the all the
regenerated bits too.
Bootstrapped/regtested on x86_64-linux and i686-linux (without any of
--enable-cet*/--disable-cet, with no -fct-protection -mcet in libraries,
change compared to previous bootstrap), additionally tested
(non-bootstrap build) with --enable-cet=auto, --disable-cet and --enable-cet .
Ok for trunk?
2018-04-18 Jakub Jelinek <jakub@redhat.com>
* config/cet.m4 (GCC_CET_FLAGS): Default to --disable-cet, replace
--enable-cet=default with --enable-cet=auto.
* doc/install.texi: Document --disable-cet being the default and
--enable-cet=auto.
* configure: Regenerated.
