libunwind/tests/Makefile.am
H.J. Lu 155b3d90f4 x86-64: Add a configure option to enable Intel CET 
1. Add a configure option, --enable-cet, to compile libunwind with
   "-mshstk -fcf-protection" and link with -Wl,-z,cet-report=error.
   CET is always enabled if -fcf-protection is on by default.
2. Add a frames field to struct cursor and update unw_step to cont stack
frames to pop.
3. Update x86_64_sigreturn to pop 4 shadow stack frames.
4. Update x86_64_local_resume to pop the same number of shadow stack
frames as the regular stack frames.
5. Update _Ux86_64_setcontext to pop 2 shadow stack frames.

There are no failures with

$ ./configure --enable-cet
$ make -j12
$ GLIBC_TUNABLES=glibc.cpu.hwcaps=SHSTK make check

on Linux when shadow stack is enabled.
