Intel Control-flow Enforcement Technology (CET): https://software.intel.com/en-us/articles/intel-sdm
contains shadow stack (SHSTK) and indirect branch tracking (IBT). When CET is enabled, ELF object files must be marked with .note.gnu.property section. Also when IBT is enabled, all indirect branch targets must start with ENDBR instruction and notrack prefix can be used to disable IBT on indirect branch. This patch series defines 3 macros: 1. X86_ENDBR. Defined as endbr32/endbr64 if CET is enabled. 2. X86_NOTRACK. Defined as notrack prefix if CET is enabled. 3. X86_GNU_PROPERTY. Add a .note.gnu.property section to mark Intel CET support if needed. and uses them to enable Intel CET. Tested with $ CC="gcc -Wl,-z,cet-report=error -fcf-protection" ./configure in i686, x32 and x86-64 modes on Linux CET machine. H.J.
