./devel/gmp, Library for arbitrary precision arithmetic

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 6.3.0, Package name: gmp-6.3.0, Maintainer: pkgsrc-users

GNU MP is a library for arbitrary precision arithmetic, operating on signed
integers, rational numbers, and floating point numbers. It has a rich set
of functions, and the functions have a regular interface.

GNU MP is designed to be as fast as possible, both for small operands and for
huge operands. The speed is achieved by using fullwords as the basic
arithmetic type, by using fast algorithms, by carefully optimized assembly
code for the most common inner loops for a lots of CPUs, and by a general
emphasis on speed (instead of simplicity or elegance).

The speed of GNU MP is believed to be faster than any other similar library.
The advantage for GNU MP increases with the operand sizes for certain
operations, since GNU MP in many cases has asymptotically faster algorithms.

Log message:
*/builtin.mk: Use ${_CROSS_DESTDIR:U} for build-time file checks.

These are questions about the target system, whose files at
build-time are all relative to ${_CROSS_DESTDIR} if it is defined,
i.e., if USE_CROSS_COMPILE is set to yes.

No change to native builds because ${_CROSS_DESTDIR:U} is empty in
them.  (Possible minor change by adding :Q to ${H_FOO} in command
lines, but if this makes a difference it likely fixes problems.)

Log message:
gmp: updated to 6.3.0

Changes between GMP version 6.2.* and 6.3.*.

  BUGS FIXED
  * A possible overflow of type int is avoided for mpz_cmp on huge operands.

  * A possible error condition when a malformed file is read with
    mpz_inp_raw is now correctly handled.

  FEATURES
  * New public function mpz_prevprime, companion of the existing
    mpz_nextprime.

  * New documented pointer types mpz_ptr, mpz_srcptr, and similar for
    other GMP types. Refer to the manual for full list and suggested
    usage. These types have been present in gmp.h at least since
    GMP-4.0, but previously not advertised to users.

  * Support for 64-bit Arm under Macos.

  * Support for the loongarch64 CPU family.

  * Support for building with LTO, link-time optimisations.

  SPEEDUPS
  * New special code for base = 2 in mpz_powm reduces the average time
    for the functions that test primality.

  * Speedup for the function mpz_nextprime on large operands.

  * Speedup for multiplications (some sizes only) thanks to new
    internal functions to compute small negacyclic products.

  * Special assembly code for IBM z13 and later "mainframe" CPUs, \ 
resulting in
    a huge speedup.

  * Improved assembly for several 64-bit x86 CPUs, Risc-V, 64-bit Arm.

Log message:
gmp: update to 6.2.1.

Fix some pkglint while here.

Changes between GMP version 6.2.0 and 6.2.1

  BUGS FIXED
  * A possible overflow of type int is avoided for mpz_cmp on huge operands.

  * Overflows are more carefully detected and reported for mpz_pow_ui.

  * A bug in longlong.h for aarch64 sub_ddmmss, not affecting GMP, was healed.

  * mini-gmp: mpz_out_str and mpq_out_str now correctly handle out of
    range bases.

  FEATURES
  * C90 compliance.

  * Initial support for Darwin on arm64, and improved portability.

  * Support for more processors.

  SPEEDUPS
  * None, except indirectly through recognition of new CPUs.
