CVS commit: pkgsrc/devel/gmp



Module Name:    pkgsrc
Committed By:   wiz
Date:           Sun Aug 16 13:42:33 UTC 2009

Modified Files:
        pkgsrc/devel/gmp: Makefile distinfo

Log Message:
Update to 4.3.1. Add gnu-gpl-v3 to LICENSE, since README claims it
also affects some files.

Changes between GMP version 4.3.0 and 4.3.1

  Bugs:
  * Fixed bug in mpn_gcdext, affecting also mpz_gcdext and mpz_invert.
    The bug could cause a cofactor to have a leading zero limb, which
    could lead to crashes or miscomputation later on.
  * Fixed some minor documentation issues.

  Features:
  * Workarounds for various issues with Mac OS X's build tools.
  * Recognise more IBM "POWER" processor variants.

Changes between GMP version 4.2.X and 4.3.0

  Bugs:
  * Fixed bug in mpz_perfect_power_p with recognition of negative perfect
    powers that can be written both as an even and odd power.
  * We might accidentally have added bugs since there is a large amount of
    new code in this release.

  Speedups:
  * Vastly improved assembly code for x86-64 processors from AMD and Intel.
  * Major improvements also for many other processor families, such as
    Alpha, PowerPC, and Itanium.
  * New sub-quadratic mpn_gcd and mpn_gcdext, as well as improved basecase
    gcd code.
  * The multiply FFT code has been slightly improved.
  * Balanced multiplication now uses 4-way Toom in addition to schoolbook,
    Karatsuba, 3-way Toom, and FFT.
  * Unbalanced multiplication has been vastly improved.
  * Improved schoolbook division by means of faster quotient approximation.
  * Several new algorithms for division and mod by single limbs, giving
    many-fold speedups.
  * Improved nth root computations.
  * The mpz_nextprime function uses sieving and is much faster.
  * Countless minor tweaks.

  Features:
  * Updated support for fat binaries for x86_32 include current processors
  * Lots of new mpn internal interfaces.  Some of them will become public
    in a future GMP release.
  * Support for the 32-bit ABI under x86-apple-darwin.
  * x86 CPU recognition code should now default better for future
    processors.
  * The experimental nails feature does not work in this release, but
    it might be re-enabled in the future.

  Misc:
  * The gmp_version variable now always contains three parts.  For this
    release, it is "4.3.0".
