Add -z cet-report=[none|warning|error] to report the missing Intel Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK) properties in input .note.gnu.property section. -z cet-report=none, which is the default, will make the linker not report missing properties in input files. -z cet-report=warning will make the linker issue a warning for missing properties in input files. -z cet-report=error will make the linker issue an error for missing properties in input files. Note that -z ibt will turn off the missing IBT property report and -z shstk will turn off the missing SHSTK property report. Supported for Linux/i386 and Linux/x86_64. bfd/ * elf-linker-x86.h (elf_x86_cet_report): New.
