Comment (by cypherpunks):

 > The SafeStack enforcement mechanism is now part of the Clang compiler
 https://clang.llvm.org/docs/SafeStack.html

 > SafeStack is a component of Code-Pointer Separation (CPS).
 > CPS is a simplified version of Code-Pointer Integrity (CPI).
 But
 > compiling dynamic libraries with SafeStack is not supported.
 > SafeStack was tested on Linux, FreeBSD and MacOSX.
 Instead of CPS/CPI Clang prefers #20361.
