gmp-6.3.0

[Bruce Dubbs]

New minor version.

[Xi Ruoyao]

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.
