The cross-compilation library packages for gmp are now also available in
the latest version.

GNU Multiple Precision Arithmetic Library

GMP is a free library for arbitrary precision arithmetic, operating on
signed integers, rational numbers, and floating point numbers. There is
no practical limit to the precision except the ones implied by the
available memory in the machine GMP runs on. GMP has a rich set of
functions, and the functions have a regular interface.

GMP 6.3 is upwardly source and binary compatible with 6.2, 6.1, 6.0,
5.1, 5.0, 4.x, and 3.x, except for applications that use the
semi-documented mpn_bdivmod function.

Changes between GMP version 6.2.* and 6.3.0


    A possible overflow of type int is avoided for mpz_cmp on huge

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


    New public function mpz_prevprime, companion of the existing

    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.


    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.
