GMP 4.1 News

GMP 4.1 release notes

GMP 4.1 is upwardly source and binary compatible with 4.0 and 3.x, except for applications that use the semi-documented mpn_bdivmod function.

Changes between GMP version 4.1.3 and 4.1.4

Bug fix to FFT multiplication code (crash for huge operands).
Bug fix to mpf_sub (miscomputation).
Support for powerpc64-gnu-linux.
Better support for AMD64 in 32-bit mode.
Upwardly binary compatible with 4.1.3, 4.1.2, 4.1.1, 4.1, 4.0.1, 4.0, and 3.x versions.

Bug fix for FFT multiplication code (miscomputation).
Bug fix to K6 assembly code for gcd.
Bug fix to IA-64 assembly code for population count.
Portability improvements, most notably functional AMD64 support.
mpz_export allows NULL for countp parameter.
Many minor bug fixes.
Upwardly binary compatible with 4.1.2, 4.1.1, 4.1, 4.0.1, 4.0, and 3.x versions.

Bug fixes.
Speed improvements.
Asymptotically fast conversion to/from strings (mpz, mpq, mpn levels), but also major speed improvements for tiny operands.
Further improved documentation.
Major speed improvments for HPPA 2.0 systems.
Major speed improvments for UltraSPARC systems.
Major speed improvments for IA-64 systems (but still sub-optimal code).
Extended test suite.
mpfr is back, with many bug fixes and portability improvements.
New function: mpz_ui_sub.
New functions: mpz_export, mpz_import.
Optimization for nth root functions (mpz_root, mpz_perfect_power_p).
Optimization for extended gcd (mpz_gcdext, mpz_invert, mpn_gcdext).
Generalized low-level number format, reserving a `nails' part of each limb. (Please note that this is really experimental; some functions are likely to compute garbage when nails are enabled.)
Nails-enabled Alpha 21264 assembly code, allowing up to 75% better performance. (Use --enable-nails=4 to enable it.)
More we've forgotten about...
Upwardly binary compatible with 4.0, 4.0.1, and 3.x versions.
