2020-02-12Use a non-empty test program to test ability to link.Sandra Loosemore2-2/+9
On bare-metal targets, I/O support is typically provided by a BSP and requires a linker script and/or hosting library to be specified on the linker command line. 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.
2020-01-24Add `--with-toolexeclibdir=' configuration optionMaciej W. Rozycki5-4/+49
Provide means, in the form of a `--with-toolexeclibdir=' configuration option, to override the default installation directory for target libraries, otherwise known as $toolexeclibdir. This is so that it is possible to get newly-built libraries, particularly the shared ones, installed in a common place, so that they can be readily used by the target system as their host libraries, possibly over NFS, without a need to manually copy them over from the currently hardcoded location they would otherwise be installed in. In the presence of the `--enable-version-specific-runtime-libs' option and for configurations building native GCC the option is ignored. config/ * toolexeclibdir.m4: New file. gcc/ * doc/install.texi (Cross-Compiler-Specific Options): Document `--with-toolexeclibdir' option. libada/ * Makefile.in (configure_deps): Add `toolexeclibdir.m4'. * configure.ac: Handle `--with-toolexeclibdir='. * configure: Regenerate. libatomic/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. libffi/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * include/Makefile.in: Regenerate. * man/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. libgcc/ * Makefile.in (configure_deps): Add `toolexeclibdir.m4'. * configure.ac: Handle `--with-toolexeclibdir='. * configure: Regenerate. libgfortran/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libgomp/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. libhsail-rt/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libitm/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. libobjc/ * Makefile.in (aclocal_deps): Add `toolexeclibdir.m4'. * aclocal.m4: Include `toolexeclibdir.m4'. * configure.ac: Handle `--with-toolexeclibdir='. * configure: Regenerate. liboffloadmic/ * plugin/configure.ac: Handle `--with-toolexeclibdir='. * plugin/Makefile.in: Regenerate. * plugin/aclocal.m4: Regenerate. * plugin/configure: Regenerate. * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libphobos/ * m4/druntime.m4: Handle `--with-toolexeclibdir='. * m4/Makefile.in: Regenerate. * libdruntime/Makefile.in: Regenerate. * src/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libquadmath/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libsanitizer/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * asan/Makefile.in: Regenerate. * interception/Makefile.in: Regenerate. * libbacktrace/Makefile.in: Regenerate. * lsan/Makefile.in: Regenerate. * sanitizer_common/Makefile.in: Regenerate. * tsan/Makefile.in: Regenerate. * ubsan/Makefile.in: Regenerate. libssp/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libstdc++-v3/ * acinclude.m4: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * doc/Makefile.in: Regenerate. * include/Makefile.in: Regenerate. * libsupc++/Makefile.in: Regenerate. * po/Makefile.in: Regenerate. * python/Makefile.in: Regenerate. * src/Makefile.in: Regenerate. * src/c++11/Makefile.in: Regenerate. * src/c++17/Makefile.in: Regenerate. * src/c++98/Makefile.in: Regenerate. * src/filesystem/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. libvtv/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. zlib/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate.

2019-09-05Improve PRNG jumping when using threadsJanne Blomqvist2-27/+32
Currently, when a new thread needs to use the RANDOM_NUMBER intrinsic, the per-thread PRNG state is initialized by copying the master state and then jumping forwards N*2**128 entries in the stream so that the PRNG streams for different threads don't alias each other, where N is the number of threads that have so far initialized the PRNG. With this patch the master state itself is jumped forwards once each time a new thread initializes the PRNG, thus obviating the need to jump through all the N-1 previous streams. Effectively turning an O(N) algorithm into an O(1) one.

When using posix_spawn or fork to launch a child process, the parent needs to wait for the child, otherwise the dead child is left as a zombie process.

2019-05-17libfortran/90038: Use posix_spawn instead of forkJanne Blomqvist6-13/+52
fork() semantics can be problematic. Most unix style OS'es have posix_spawn which can be used to replace fork + exec in many cases. For more information see e.g. https://www.microsoft.com/en-us/research/uploads/prod/2019/04/fork-hotos19.pdf This replaces the one use of fork in libgfortran with posix_spawn. 2019-05-17 Janne Blomqvist <jb@gcc.gnu.org> PR libfortran/90038 * configure.ac (AC_CHECK_FUNCS_ONCE): Check for posix_spawn. * intrinsics/execute_command_line (execute_command_line): Use posix_spawn. * Makefile.in: Regenerated. * config.h.in: Regenerated. * configure: Regenerated.
