2023-06-22configure: Implement --enable-host-bind-nowMarek Polacek2-0/+18
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.

2023-06-15configure: Implement --enable-host-pieMarek Polacek3-8/+31
[ This is my third attempt to add this configure option. The first version was approved but it came too late in the development cycle. The second version was also approved, but I had to revert it: <https://gcc.gnu.org/pipermail/gcc-patches/2022-November/607082.html>. I've fixed the problem (by moving $(PICFLAG) from INTERNAL_CFLAGS to ALL_COMPILERFLAGS). Another change is that since r13-4536 I no longer need to touch Makefile.def, so this patch is simplified. ] 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.

2023-03-31c++tools: Fix Makefile to properly clean and rebuild [PR101834]Jonathan Wakely1-5/+7
The c++tools makefile doesn't remove progressively more files in each of mostlyclean, clean, and distclean. Instead, each removes a different set of files (and some files are not removed by any target). Use prerequisites so that everything is removed. Also, building in the $objdir/c++tools directory doesn't work, because the INSTALL variable is never set. It works when building from the top-level because INSTALL is set in the environment when recursively invoking make for sub-directories. c++tools/ChangeLog: PR bootstrap/101834 * Makefile.in (INSTALL): Set variable. (mostlyclean): Mark as a phony target. (clean): Add mostlyclean as a prerequisite. (distclean): Add clean as a prerequisite and remove more files. (maintainer-clean): Add distclean as a prerequisite.

2021-04-01modules : Make sure we include <map> in system.h.Iain Sandoe1-0/+2
It appears that many targets include the map header transitively in other std headers included from system.h. However there are some editions of clang/libc++ in Xcode that do not, which results in a bootstrap fail - since when resolver.h is included there is then a conflict in declaring abort(). The fix is to ensure that map is pulled in by system.h and before resolver.h is included.

2021-01-05build: libcody: Link with -lsocket -lnsl if necessary [PR98316]Rainer Orth3-1/+223
With the introduction of C++20 modules and libcody, cc1plus and cc1objplus gained a dependency on the socket functions. Before those were merged into libc in Solaris 11.4, one needed to link with -lsocket -lnsl on Solaris, so that merge broke the Solaris 11.3 build. While we already have 4 different checks for those libraries in the tree, I decided to import autoconf-archive's AX_LIB_SOCKET_NSL macro instead. At the same time, the patch only links libcody and the networking libs where needed (cc1plus, cc1objplus). Bootstrapped without regressions on i386-pc-solaris2.11 (Solaris 11.3 and 11.4), sparc-sun-solaris2.11, and x86_64-pc-linux-gnu. 2020-12-16 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> c++tools: PR c++/98316 * configure.ac: Include ../config/ax_lib_socket_nsl.m4.

2021-01-04[libcody] Remove some std::move [PR 98368]Nathan Sidwell1-3/+1
Compiling on clang showed a couple of pessimizations. Fixed thusly. libcody/ * client.cc (Client::ProcessResponse): Remove std::move inside ?: c++tools/ * resolver.cc (module_resolver::cmi_response): Remove std::move of temporary.

2020-12-23c++tools: Fix PIE [PR 98324]Nathan Sidwell3-2/+24
This adds --enable-default-pie support to c++tools, so that the sample server is build -fPIE if requested. PR bootstrap/98324 c++tools/ * Makefile.in: Add FLAGPIE. * configure.ac: Add --enable-default-pie support. * configure: Rebuilt.

2020-12-21c++tools: Fix exe suffix [PR 98409]Nathan Sidwell1-1/+1
I had a thinko about variable case, and, coupled with Make's behaviour of just consing up variables out of nothing, and linux not having an executable extension, didn't notice. PR other/98409 c++tools/ * Makefile.in: Fix exeext variable case.

2020-12-17bootstrap: Don't use strsignal [PR 98300]Nathan Sidwell1-1/+2
Sadly strsignal is nonportable, so signal numbers it is then. c++tools/ * server.cc (crash_signal): Don't use strsignal.
2020-12-17bootstrap: Fix some windows issues [PR 98300]Nathan Sidwell4-3/+726
When breaking out the sample server from the gcc/cp directory, it lost its check for mmap, and the sample resolver just assumed it was there. Fixed thusly. The non-mapping paths in module.cc weren't (recently) excercised, and led to a signedness warning. Finally I'd missed c++tools's config.h.in in the gcc_update script. There I took the opportunity of adding a 'tools' segment of the dependency lists. PR bootstrap/98300 contrib/ * gcc_update: Add c++tools/config.h.in. c++tools/ * configure.ac: Check for sys/mman.h. * resolver.cc: Don't assume mmap, O_CLOEXEC are available. Use xmalloc. * config.h.in: Regenerated. * configure: Regenerated. gcc/cp/ * module.cc: Fix ::read, ::write result signedness comparisons.
2020-12-17c++tools: Fix up c++tools for --with-gcc-major-version-onlyJakub Jelinek3-2/+28
Seems c++tools doesn't honor --with-gcc-major-version-only. Our distro uses that flag and so everything is installed in /usr/lib/gcc/<target>/11/... /usr/libexec/gcc/<target>/11/... except /usr/libexec/gcc/<target>/11.0.0/g++-mapper-server The following patch should fix that. 2020-12-17 Jakub Jelinek <jakub@redhat.com> * configure.ac: Add GCC_BASE_VER. * Makefile.in (version): Remove variable. (gcc_version): New variable. (libexecsubdir): Use $(gcc_version) instead of $(version). * configure: Regenerated.
