This is "mini-gmp", a small implementation of a subset of GMP's mpn
and mpz interfaces.

It is intended for applications which need arithmetic on numbers
larger than a machine word, but which don't need to handle very large
numbers very efficiently. Those applications can include a copy of
mini-gmp to get a GMP-compatible interface with small footprint. One
can also arrange for optional linking with the real GMP library, using
mini-gmp as a fallback when for some reason GMP is not available, or
not desired as a dependency.

The supported GMP subset is declared in mini-gmp.h. The implemented
functions are fully compatible with the corresponding GMP functions,
as specified in the GMP manual, with a few exceptions:

  mpz_set_str, mpz_init_set_str, mpz_get_str, mpz_out_str and
  mpz_sizeinbase support only |base| <= 36;
  mpz_export and mpz_import support only NAILS = 0.

  The REALLOC_FUNC and FREE_FUNC registered with
  mp_set_memory_functions does not get the correct size of the
  allocated block in the corresponding argument. mini-gmp always
  passes zero for these rarely used arguments.

The implementation is a single file, mini-gmp.c.

The performance target for mini-gmp is to be at most 10 times slower
than the real GMP library, for numbers of size up to a few hundred
bits. No asymptotically fast algorithms are included in mini-gmp, so
it will be many orders of magnitude slower than GMP for very large
numbers.

You should never "install" mini-gmp. Applications can either just
#include mini-gmp.c (but then, beware that it defines several macros
and functions outside of the advertised interface). Or compile
mini-gmp.c as a separate compilation unit, and use the declarations in
mini-gmp.h.

The tests subdirectory contains a testsuite. To use it, you need GMP
and GNU make. Just run make check in the tests directory. If the
hard-coded compiler settings are not right, you have to either edit the
Makefile or pass overriding values on the make command line (e.g.,
make CC=cc check). Testing is not (yet) as thorough as for the real
GMP.

The current version was put together by Niels Möller
<nisse@@lysator.liu.se>, with a fair amount of copy-and-paste from the
GMP sources.

1.1.1.2
log
@initial import of GMP 6.1.2.  main changes from 5.1.3 below.

notes:
 - support for thumb-less ARM chips was in our port of 5.1.3, but a
   similar method has been provided upstream now
 - someone should look at the AVX failure reports, and fix them

Changes between GMP version 6.1.0 and 6.1.1

  FEATURES
  * Work around faulty cpuid on some recent Intel chips (this allows GMP to run
    on Skylake Pentiums).
  * Support thumb-less ARM chips.

Changes between GMP version 6.0.* and 6.1.0

  BUGS FIXED
  * The public function mpn_com is now correctly declared in gmp.h.
  * Healed possible failures of mpn_sec_sqr for non-cryptographic sizes for
    some obsolete CPUs.
  * Various problems related to precision for mpf have been fixed.
  * Fixed ABI incompatible stack alignment in calls from assembly code.
  * Fixed PIC bug in popcount affecting Intel processors using the 32-bit ABI.
  SPEEDUPS
  * Speedup for Intel Broadwell and Skylake through assembly code making use of
    new ADX instructions.
  * Square root is now faster when the remainder is not needed. Also the speed
    to compute the k-th root improved, for small sizes.
  FEATURES
  * New C++ functions gcd and lcm for mpz_class.
  * New public mpn functions mpn_divexact_1, mpn_zero_p, and mpn_cnd_swap.
  * New public mpq_cmp_z function, to efficiently compare rationals with
    integers.
  * Support for more 32-bit arm processors.
  * Support for AVX-less modern x86 CPUs. (Such support might be missing either
    because the CPU vendor chose to disable AVX, or because the running kernel
    lacks AVX context switch support.)
  * Support for NetBSD under Xen; we switch off AVX unconditionally under
    NetBSD since a bug in NetBSD makes AVX fail under Xen.
  MISC
  * Tuned values for FFT multiplications are provided for larger number on
    many platforms.

Changes between GMP version 5.1.* and 6.0.0
  BUGS FIXED
  * The function mpz_invert now considers any number invertible in Z/1Z.
  * The mpn multiply code now handles operands of more than 2^31 limbs
    correctly.  (Note however that the mpz code is limited to 2^32 bits on
    32-bit hosts and 2^37 bits on 64-bit hosts.)
  SPEEDUPS
  * Plain division of large operands is faster and more monotonous in operand
    size.
  * Major speedup for ARM, in particular ARM Cortex-A15, thanks to improved
    assembly.
  * Speedup for Intel Sandy Bridge, Ivy Bridge, Haswell, thanks to rewritten
    and vastly expanded assembly support.  Speedup also for the older Core 2
    and Nehalem.
  * Faster mixed arithmetic between mpq_class and double.
  FEATURES
  * Support for new Intel and AMD CPUs.
  * New public functions mpn_sec_mul and mpn_sec_sqr, implementing side-channel
    silent multiplication and squaring.
  * New public functions mpn_sec_div_qr and mpn_sec_div_r, implementing
    side-channel silent division.
  * New public functions mpn_cnd_add_n and mpn_cnd_sub_n.  Side-channel silent
    conditional addition and subtraction.
  * New public function mpn_sec_powm, implementing side-channel silent modexp.
  * New public function mpn_sec_invert, implementing side-channel silent
    modular inversion.
  * Better support for applications which use the mpz_t type, but nevertheless
    need to call some of the lower-level mpn functions.  See the documentation
    for mpz_limbs_read and related functions.
