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.
Version 6.1.0 is an upstream release fully binary and ABI compatible
with the 6.0.0 and 5.x versions.
GMP 6.1.0 release announcement
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.
The option --disable-assembly now disables all inlined asm.
Fixed bug affecting mini-gmp's bitwise functions mpz_setbit,
mpz_clrbit, and mpz_combit.
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
Speedup for Intel Broadwell and Skylake though 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.
Improved arm64 support.
New C++ functions gcd and lcm for mpz_class.
New public mpn functions mpn_divexact_1, mpn_zero_p, and
New public mpq_cmp_z function, to efficiently compare rationals with
Support for Darwin in all x86 code, thereby enabling fat builds on
Support for more 32-bit arm processors.
Support for compilation with clang/llvm on more platforms. Caution:
GMP triggers mis-compilation bugs in clang for many platforms, such
as arm, x86 (32-bit and 64-bit), powerpc, mips.
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.)
Stack usage trimmed; we believe 512 KiB is now sufficient for any
GMP call, irrespective of operand size.
Support for NetBSD under Xen; we switch off AVX unconditionally
under NetBSD since a bug in NetBSD makes AVX fail under Xen.
We now use manufacturers' code names for x86 CPUs, e.g., "haswell"
instead of names derived from the commercial brands.
Small improvements and better coverage for the test suite.
The various FreeBSD problems listed for 6.0.0 affect this release
Tuned values for FFT multiplications are provided for larger number
on many platforms.
This release would not have been possible without the continuous work of
improvement, revision and refinement by the whole GMP team: Torbjörn
Granlund, Niels Möller, Marco Bodrato, and Marc Glisse.
