2020-04-22libgfortran: Provide some further math library fallbacks [PR94694]Jakub Jelinek
The following patch provides some further math library fallbacks. fmaf can be implemented using fma if available, fma and fmal can use x * y + z as fallback, it is not perfect, but e.g. glibc on various arches has been using that as fallback for many years, and copysign/copysignl/fabs/fabsl can be implemented using corresponding __builtin_* if we make sure that gcc expands it inline instead of using a library call (these days it is expanded inline on most targets). 2020-04-22 Jakub Jelinek <jakub@redhat.com> PR libfortran/94694 PR libfortran/94586 * configure.ac: Add math func checks for fmaf, fma and fmal.

2020-02-12Use a non-empty test program to test ability to link.Sandra Loosemore
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. Rozycki
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.

2018-11-22Replace sync builtins with atomic builtinsJanne Blomqvist
The old __sync builtins have been deprecated for a long time now in favor of the __atomic builtins following the C++11/C11 memory model. This patch converts libgfortran to use the modern __atomic builtins. At the same time I weakened the consistency to relaxed for incrementing and decrementing the counter, and acquire-release when decrementing to check whether the counter is 0 and the unit can be freed. This is similar to e.g. std::shared_ptr in C++.

2018-10-31Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).Joseph Myers
This patch updates GCC to use autoconf 2.69 and automake 1.15.1. (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.

2018-09-21Use vectored writes when reporting errors and warnings.Janne Blomqvist
When producing error and warning messages, libgfortran writes a message by using many system calls. By using vectored writes (the POSIX writev function) when available and feasible to use without major surgery, we reduce the chance that output gets intermingled with other output to stderr. In practice, this is done by introducing a new function estr_writev in addition to the existing estr_write. In order to use this, the old st_vprintf is removed, replaced by direct calls of vsnprintf, allowing more message batching.

2018-08-13Use getentropy() for seeding PRNGJanne Blomqvist
The getentropy function, found on Linux, OpenBSD, and recently also FreeBSD, can be used to get random bytes to initialize the PRNG. It is similar to the traditional way of reading from /dev/urandom, but being a system call rather than a special file, it doesn't suffer from problems like running out of file descriptors, or failure when running in a container where /dev/urandom may not be available.
