This patch implements the --enable-host-pie configure option which makes the compiler executables PIE. This can be used to enhance protection against ROP attacks, and can be viewed as part of a wider trend to harden binaries. It is similar to the option --enable-host-shared, except that --e-h-s won't add -shared to the linker flags whereas --e-h-p will add -pie. It is different from --enable-default-pie because that option just adds an implicit -fPIE/-pie when the compiler is invoked, but the compiler itself isn't PIE. Since r12-5768-gfe7c3ecf, PCH works well with PIE, so there are no PCH regressions. When building the compiler, the build process may use various in-tree libraries; these need to be built with -fPIE so that it's possible to use them when building a PIE. For instance, when --with-included-gettext is in effect, intl object files must be compiled with -fPIE. Similarly, when building in-tree gmp, isl, mpfr and mpc, they must be compiled with -fPIE. I plan to add an option to link with -Wl,-z,now. ChangeLog: * Makefile.def: Pass $(PICFLAG) to AM_CFLAGS for gmp, mpfr, mpc, and isl. * Makefile.in: Regenerate. * Makefile.tpl: Set PICFLAG. * configure.ac (--enable-host-pie): New check. Set PICFLAG after this check. * configure: Regenerate. c++tools/ChangeLog: * Makefile.in: Rename PIEFLAG to PICFLAG. Set LD_PICFLAG. Use it. Use pic/libiberty.a if PICFLAG is set. * configure.ac (--enable-default-pie): Set PICFLAG instead of PIEFLAG. (--enable-host-pie): New check. * configure: Regenerate. fixincludes/ChangeLog: * Makefile.in: Set and use PICFLAG and LD_PICFLAG. Use the "pic" build of libiberty if PICFLAG is set. * configure.ac: * configure: Regenerate. gcc/ChangeLog: * Makefile.in: Set LD_PICFLAG. Use it. Set enable_host_pie. Remove NO_PIE_CFLAGS and NO_PIE_FLAG. Pass LD_PICFLAG to ALL_LINKERFLAGS. Use the "pic" build of libiberty if --enable-host-pie. * configure.ac (--enable-host-shared): Don't set PICFLAG here. (--enable-host-pie): New check. Set PICFLAG and LD_PICFLAG after this check. * configure: Regenerate. * doc/install.texi: Document --enable-host-pie. gcc/d/ChangeLog: * Make-lang.in: Remove NO_PIE_CFLAGS. intl/ChangeLog: * Makefile.in: Use @PICFLAG@ in COMPILE as well. * configure.ac (--enable-host-shared): Don't set PICFLAG here. (--enable-host-pie): New check. Set PICFLAG after this check. * configure: Regenerate. libcody/ChangeLog: * Makefile.in: Pass LD_PICFLAG to LDFLAGS. * configure.ac (--enable-host-shared): Don't set PICFLAG here. (--enable-host-pie): New check. Set PICFLAG and LD_PICFLAG after this check. * configure: Regenerate. libcpp/ChangeLog: * configure.ac (--enable-host-shared): Don't set PICFLAG here. (--enable-host-pie): New check. Set PICFLAG after this check. * configure: Regenerate. libdecnumber/ChangeLog: * configure.ac (--enable-host-shared): Don't set PICFLAG here. (--enable-host-pie): New check. Set PICFLAG after this check. * configure: Regenerate. libiberty/ChangeLog: * configure.ac: Also set shared when enable_host_pie. * configure: Regenerate. zlib/ChangeLog: * configure.ac (--enable-host-shared): Don't set PICFLAG here. (--enable-host-pie): New check. Set PICFLAG after this check. * configure: Regenerate.
