--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
I don't think PTA_SHSTK is needed since -mshstk is only used to enable CET
in run-time library which is backward compatible.  GCC run-time libraries
are compiled with -mshstk when CET is enabled.  As for IBT, ENDBR is
generated with -fcf-protection for all processors.

The whole CET thing is backward compatible.  We don't need to add PTA_SHSTK
to Tiger Lake.
