A new release of the GNU Multiple Precision Arithmetic Library (GMP) is now available. The new release is identified as 5.0.3.
The new release can be downloaded from the main GNU ftp site: xz format: ftp://ftp.gnu.org/gnu/gmp/gmp-5.0.3.tar.xz bzip2 format: ftp://ftp.gnu.org/gnu/gmp/gmp-5.0.3.tar.bz2 These files can also be found from the main GMP domain, e.g. ftp://ftp.gmplib.org/pub/gmp/gmp-5.0.3.tar.xz. The changes between this release and the previous release are limited to various safe bug fixes and portability improvements. GMP 5.0 is the currently maintained stable release series; we recommend everyone to switch from earlier GMP releases to GMP 5.0.3. While GMP bugs do happen, the absolutely most common cause for incorrect computations with GMP is bugs in the compiler used for building he library. It cannot be said enough times: Please run "make check" after you've built GMP. And if "make check" stops with an error, do not use the compiled library. When this happens, you've almost surely run into a compiler bug, not a library bug, since we've of course made sure the library passes its own test suite. The first thing to try at this point is using a different compiler. See also http://gmplib.org/. GCC version 4.3.2 is known to miscompile this GMP release on all 64-bit platforms; this manifests itself at a check failure in tests/mpz/t-root.c. The GMP 5.0 release series would not have been possible without the very devoted work of Niels Möller and Marco Bodrato. Torbjörn Granlund coordinated the development and release, and did a fair amount of development work himself. Marc Glisse helped with the C++ wrapper. Changes between GMP version 5.0.2 and 5.0.3 BUGS FIXED * A few minor bugs related to portability fixed. * A slight timing leak of the powm_sec functions have been sealed. (This leak could possibly be used to extract the most significant few bits of the exponent. "Few" here means at most 10.) * The mpz_nextprime function now runs a safer number of pseudo-random prime tests. * A bug in division code possibly causing incorrect computation was fixed. SPEEDUPS * None, except indirectly through recognition of new CPUs, and through better tuning parameters. FEATURES * New CPUs recognised. * IBM S/390 are now supported in both 31/32-bit and 64-bit mode. (We have not been able to fully test this on any multilib machine, since IBM expired our guest account a few days before our release.) MISC * None. There is a public repository for GMP, please see the GMP web site at http://gmplib.org/ for more information. Torbjörn's work on GMP is sponsored by "Stiftelsen för Strategisk Forskning", through CIAM at KTH, http://www.ciam.kth.se/. -- Torbjörn _______________________________________________ GNU Announcement mailing list <info-gnu@gnu.org> https://lists.gnu.org/mailman/listinfo/info-gnu
