Igor Tsimbalist 1ecae1fc23 Enable building libgcc with CET options. ... Enable building libgcc with CET options by default on Linux/x86 if binutils supports CET v2.0. It can be disabled with --disable-cet. It is an error to configure GCC with --enable-cet if bintuiils doesn't support CET v2.0. ENDBR instruction is added to __morestack_large_model since it is called indirectly. 2017-11-17 Igor Tsimbalist <igor.v.tsimbalist@intel.com> config/ * cet.m4: New file. gcc/ * config.gcc (extra_headers): Add cet.h for x86 targets. * config/i386/cet.h: New file. * doc/install.texi: Add --enable-cet/--disable-cet. libgcc/ * Makefile.in (configure_deps): Add $(srcdir)/../config/cet.m4. (CET_FLAGS): New. * config/i386/morestack.S: Include <cet.h>. (__morestack_large_model): Add _CET_ENDBR at function entrance. * config/i386/resms64.h: Include <cet.h>. * config/i386/resms64f.h: Likewise. * config/i386/resms64fx.h: Likewise. * config/i386/resms64x.h: Likewise. * config/i386/savms64.h: Likewise. * config/i386/savms64f.h: Likewise. * config/i386/t-linux (HOST_LIBGCC2_CFLAGS): Add $(CET_FLAGS). (CRTSTUFF_T_CFLAGS): Likewise. * configure.ac: Include ../config/cet.m4. Set and substitute CET_FLAGS. * configure: Regenerated. From-SVN: r254868		2017-11-17 14:34:39 +01:00
