Igor Tsimbalist 14e335edc8 CET shouldn't be enabled in 32-bit run-time libraries by defualt ... 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 for enable_cet. GCC will enable CET in 32-bit run-time libraries in any case if --enable-cet is used to configure GCC. PR target/84148 * config/cet.m4: Check if target support multi-byte NOPS (SSE). * libatomic/configure: Regenerate. * libbacktrace/configure: Likewise. * libgcc/configure: Likewise. * libgfortran/configure: Likewise. * libgomp/configure: Likewise. * libitm/configure: Likewise. * libmpx/configure: Likewise. * libobjc/configure: Likewise. * libquadmath/configure: Likewise. * libsanitizer/configure: Likewise. * libssp/configure: Likewise. * libstdc++-v3/configure: Likewise. * libvtv/configure: Likewise.
