Marek Polacek 258d7149f9 configure: Implement --enable-host-bind-now ... As promised in the --enable-host-pie patch, this patch adds another configure option, --enable-host-bind-now, which adds -z now when linking the compiler executables in order to extend hardening. BIND_NOW with RELRO allows the GOT to be marked RO; this prevents GOT modification attacks. This option does not affect linking of target libraries; you can use LDFLAGS_FOR_TARGET=-Wl,-z,relro,-z,now to enable RELRO/BIND_NOW. c++tools/ChangeLog: * configure.ac (--enable-host-bind-now): New check. * configure: Regenerate. gcc/ChangeLog: * configure.ac (--enable-host-bind-now): New check. Add -Wl,-z,now to LD_PICFLAG if --enable-host-bind-now. * configure: Regenerate. * doc/install.texi: Document --enable-host-bind-now. lto-plugin/ChangeLog: * configure.ac (--enable-host-bind-now): New check. Link with -z,now. * configure: Regenerate.		2022-11-22 20:47:49 -05:00
