Control-flow Enforcement Technology (CET) provides the following
capabilities to defend against ROP/JOP style control-flow subversion
attacks:
- Shadow Stack - return address protection to defend against Return
Oriented Programming,
- Indirect branch tracking - free branch protection to defend
Thanks for the feedback. I'll redo the patch according to your comments.

The revised patch is attached. The differences are in what options are defined
and propagated to Makefiles for CET enabling.
Ok for trunk?

According to the description of inssp instruction from Intel CET it adusts the
shadow stack pointer (ssp) only by value in the range of [0..255]. As a number
of adjustment could be greater than 255 there should be a loop generated to
adjust ssp.

This is a follow up patch for pr83488 to fix an error in setting
OPTION_MASK_ISA_AVX512VNNI_SET and OPTION_MASK_ISA_AVX512F_SET bits.
There were both set in ix86_isa_flags2 while being defined in
different ISA sets. Additionally move OPTION_MASK_ISA_AVX512VNNI_SET
to ix86_isa_flags as it can be use

ENDBR32 and RDSSPD are multi-byte NOPs on x86-64 processors and
newer x86 processors, starting Pentium Pro. They are UD on older 32-bit
processors. Detect this at configure time and adjust the default value

MPX is going to be deprecated in gcc-8. Control-flow protection support is in

The incspp instruction from CET accepts only the value in the range of 0-255.
The patch fixes the typo in the loop to handle this.
I'm checking in the fix as obvious.
