* configure: Allow host fragments to react to --enable-host-shared.Iain Sandoe2021-08-181-0/+8
| | | | | | | | | | | | | | | | | | | | | This makes the host_shared value available to host makefile fragments. It uses this to adjust Darwin's mdynamic-no-pic in the case that shared host resources are required. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> ChangeLog: * Makefile.in: Regenerate. * Makefile.tpl: Make the state of the configured host shared flag available to makefile fragements. config/ChangeLog: * mh-darwin: Require a non-shared host configuration to enable mdynamic-no-pic where that is supported.

* Darwin, config: Revise host config fragment.Iain Sandoe2021-07-091-24/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were two uses for the Darwin host config fragment: The first is to arrange for targets that support mdynamic-no-pic to be built with that enabled (since it makes a significant difference to the compiler performance). We can be more specific in the application of this, since it only applies to 32b hosts plus powerpc64-darwin9. The second was to work around a tool bug where -fno-PIE was not propagated to the link stage. This second use is redundant, since the buggy toolchain cannot bootstrap current GCC sources anyway. This makes the host fragment more specific and reduces the number of toolchains for which it is included which reduces clutter in configure lines. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> config/ChangeLog: * mh-darwin: Make this specific to handling the mdynamic-no-pic case. ChangeLog: * configure: Regenerate. * configure.ac: Adjust cases for which it is necessary to include the Darwin host config fragment.

* build: libcody: Link with -lsocket -lnsl if necessary [PR98316]Rainer Orth2021-01-051-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* libsanitizer: mid-end: Introduce stack variable handling for HWASANMatthew Malcomson2020-11-251-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handling stack variables has three features. 1) Ensure HWASAN required alignment for stack variables When tagging shadow memory, we need to ensure that each tag granule is only used by one variable at a time. This is done by ensuring that each tagged variable is aligned to the tag granule representation size and also ensure that the end of each object is aligned to ensure the start of any other data stored on the stack is in a different granule. This patch ensures the above by forcing the stack pointer to be aligned before and after allocating any stack objects. Since we are forcing alignment we also use `align_local_variable` to ensure this new alignment is advertised properly through SET_DECL_ALIGN. 2) Put tags into each stack variable pointer Make sure that every pointer to a stack variable includes a tag of some sort on it. The way tagging works is: 1) For every new stack frame, a random tag is generated. 2) A base register is formed from the stack pointer value and this random tag. 3) References to stack variables are now formed with RTL describing an offset from this base in both tag and value. The random tag generation is handled by a backend hook. This hook decides whether to introduce a random tag or use the stack background based on the parameter hwasan-random-frame-tag. Using the stack background is necessary for testing and bootstrap. It is necessary during bootstrap to avoid breaking the `configure` test program for determining stack direction. Using the stack background means that every stack frame has the initial tag of zero and variables are tagged with incrementing tags from 1, which also makes debugging a bit easier. Backend hooks define the size of a tag, the layout of the HWASAN shadow memory, and handle emitting the code that inserts and extracts tags from a pointer. 3) For each stack variable, tag and untag the shadow stack on function prologue and epilogue. On entry to each function we tag the relevant shadow stack region for each stack variable. This stack region is tagged to match the tag added to each pointer to that variable. This is the first patch where we use the HWASAN shadow space, so we need to add in the libhwasan initialisation code that creates this shadow memory region into the binary we produce. This instrumentation is done in `compile_file`. When exiting a function we need to ensure the shadow stack for this function has no remaining tags. Without clearing the shadow stack area for this stack frame, later function calls could get false positives when those later function calls check untagged areas (such as parameters passed on the stack) against a shadow stack area with left-over tag. Hence we ensure that the entire stack frame is cleared on function exit. config/ChangeLog: * bootstrap-hwasan.mk: Disable random frame tags for stack-tagging during bootstrap. gcc/ChangeLog: * asan.c (struct hwasan_stack_var): New.

Linking an empty program with the default linker script may succeed, however, which confuses libstdc++ configuration when programs that probe for the presence of various I/O features fail with link errors. 2020-02-12 Sandra Loosemore <sandra@codesourcery.com> PR libstdc++/79193 PR libstdc++/88999 config/ * no-executables.m4: Use a non-empty program to test for linker support. libgcc/ * configure: Regenerated. libgfortran/ * configure: Regenerated. libiberty/ * configure: Regenerated. libitm/ * configure: Regenerated. libobjc/ * configure: Regenerated. libquadmath/ * configure: Regenerated. libssp/ * configure: Regenerated. libstdc++v-3/ * configure: Regenerated.

First I failed to correctly regenerate all of the configure files it should have done. Second, there was a mistake in lib-link.m4, one of the conditions didn't use pure sh syntax, I wrote this: if x$lib_type = xauto || x$lib_type = xshared; then When I should have written this: if test "x$lib_type" = "xauto" || test "x$lib_type" = "xshared"; then These issues were raised on the mailing list in these messages: https://gcc.gnu.org/ml/gcc-patches/2020-01/msg01827.html https://gcc.gnu.org/ml/gcc-patches/2020-01/msg01921.html config/ChangeLog: * lib-link.m4 (AC_LIB_LINKFLAGS_BODY): Update shell syntax. gcc/ChangeLog: * configure: Regenerate. intl/ChangeLog: * configure: Regenerate. libcpp/ChangeLog: * configure: Regenerate. libstdc++-v3/ChangeLog: * configure: Regenerate.

Further, my motivation is really for linking libraries into GDB, however, the binutils-gdb/config/ directory is a copy of gcc/config/ so changes for GDB need to be approved by the GCC project first. After making this change in the gcc/config/ directory I've run autoreconf on all of the configure scripts in the GCC tree and a couple have been updated, so I'll use one of these to describe what my change does. Consider libcpp, this library links against libiconv. Currently if the user builds on a system with both static and dynamic libiconv installed then autotools will pick up the dynamic libiconv by default. This is almost certainly the right thing to do. However, if the user wants to link against static libiconv then things are a little harder, they could remove the dynamic libiconv from their system, but this is probably a bad idea (other things might depend on that library), or the user can build their own version of libiconv, install it into a unique prefix, and then configure gcc using the --with-libiconv-prefix=DIR flag. This works fine, but is somewhat annoying, the static library available, I just can't get autotools to use it. My change then adds a new flag --with-libiconv-type=TYPE, where type is either auto, static, or shared. The default auto, ensures we keep the existing behaviour unchanged. If the user configures with --with-libiconv-type=static then the configure script will ignore any dynamic libiconv it finds, and will only look for a static libiconv, if no static libiconv is found then the configure will continue as though there is no libiconv at all available. Similarly a user can specify --with-libiconv-type=shared and force the use of shared libiconv, any static libiconv will be ignored. As I've implemented this change within the AC_LIB_LINKFLAGS_BODY macro then only libraries configured using the AC_LIB_LINKFLAGS or AC_LIB_HAVE_LINKFLAGS macros will gain the new configure flag. If this is accepted into GCC then there will be follow on patches for binutils and GDB to regenerate some configure scripts in those projects. For GCC only two configure scripts needed updated after this commit, libcpp and libstdc++-v3, both of which link against libiconv. config/ChangeLog: * lib-link.m4 (AC_LIB_LINKFLAGS_BODY): Add new --with-libXXX-type=... option. Use this to guide the selection of either a shared library or a static library. libcpp/ChangeLog: * configure: Regenerate. libstdc++-v3/ChangeLog: * configure: Regenerate.

(That's not the latest automake version, but it's the one used by binutils-gdb, with which consistency is desirable, and in any case seems a useful incremental update that should make a future update to 1.16.1 easier.) The changes are generally similar to the binutils-gdb ones, and are copied from there where shared files and directories are involved (there are some further changes to such shared directories, however, which I'd expect to apply to binutils-gdb once this patch is in GCC). Largely, obsolete AC_PREREQ calls are removed, while many AC_LANG_SOURCE calls are added to avoid warnings from aclocal and autoconf. Multilib support is no longer included in core automake, meaning that multilib.am needs copying from automake's contrib directory into the GCC source tree. Autoconf 2.69 has Go support, so local copies of that support are removed. I hope the D support will soon be submitted to upstream autoconf so the local copy of that can be removed in a future update. Changes to how automake generates runtest calls mean quotes are removed from RUNTEST definitions in five lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm, libphobos, libvtv; some others have RUNTEST definitions without quotes, which are still OK); libgo and libphobos also get -Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST do not generate automake warnings. Note that the regeneration did not include regeneration of fixincludes/config.h.in (attempting such regeneration resulted in all the USED_FOR_TARGET conditionals disappearing; and I don't see anything in the fixincludes/ directory that would result in such conditionals being generated, unlike in the gcc/ directory). Also note that libvtv/testsuite/other-tests/Makefile.in was not regenerated; that directory is not listed as a subdirectory for which Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm not sure how it's meant to be regenerated. While I mostly fixed warnings should running aclocal / automake / autoconf, there were various such warnings from automake in the libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos directories that I did not fix, preferring to leave those to the relevant subsystem maintainers. Specifically, most of those warnings were of the following form (example from libgfortran): Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory, Makefile.am:48: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. I think it's best for the relevant maintainers to add subdir-objects and do any other associated Makefile.am changes needed. In some cases the paths in the warnings involved ../; I don't know if that adds any extra complications to the use of subdir-objects. I've tested this with native, cross and Canadian cross builds. The risk of any OS-specific issues should I hope be rather lower than if a libtool upgrade were included (we *should* do such an upgrade at some point, but it's more complicated - it involves identifying all our local libtool changes to see if any aren't included in the upstream version we update to, and reverting an upstream libtool patch that's inappropriate for use in GCC); I think it would be better to get this update into GCC so that people can test in different configurations and we can fix any issues found, rather than to try to get more and more testing done before it goes in. top level: 2018-10-31 Joseph Myers <joseph@codesourcery.com> PR bootstrap/82856 * multilib.am: New file.
