1.1.1.2 maekawa 6: Changes between MP version 3.0 and 3.1
7:
8: * Bug fixes.
9: * Improved `make check' running more tests.
10: * Tuned algorithm cutoff points for many machines. This will improve speed for
11: a lot of operations, in some cases by a large amount.
12: * Major speed improvments: Alpha 21264.
13: * Some speed improvments: Cray vector computers, AMD K6 and Athlon, Intel P5
14: and Pentium Pro/II/III.
15: * The mpf_get_prec function now works as it did in GMP 2.
16: * New utilities for auto-tuning and speed measuring.
17: * Multiplication now optionally uses FFT for very large operands. (To enable
18: it, pass --enable-fft to configure.)
19: * Support for new systems: Solaris running on x86, FreeBSD 5, HP-UX 11, Cray
20: vector computers, Rhapsody, Nextstep/Openstep, MacOS.
21: * Support for shared libraries on 32-bit HPPA.
22: * New integer functions: mpz_mul_si, mpz_odd_p, mpz_even_p.
23: * New Kronecker symbol functions: mpz_kronecker_si, mpz_kronecker_ui,
24: mpz_si_kronecker, mpz_ui_kronecker.

28: * New EXPERIMENTAL function layer for accurate floating-point arithmetic, mpfr.
29: To try it, pass --enable-mpfr to configure. See the mpfr subdirectory for
30: more information; it is not documented in the main GMP manual.
31:

33:
34: * Memory leaks in gmp_randinit and mpz_probab_prime_p fixed.

70:
71: * Many bug fixes.
72:
73: Changes between MP version 1.3.2 and 2.0
1.1 maekawa 74:
75: * Division routines in the mpz class have changed. There are three classes of
76: functions, that rounds the quotient to -infinity, 0, and +infinity,
77: respectively. The first class of functions have names that begin with
78: mpz_fdiv (f is short for floor), the second class' names begin with mpz_tdiv
79: (t is short for trunc), and the third class' names begin with mpz_cdiv (c is
80: short for ceil).
81:
82: The old division routines beginning with mpz_m are similar to the new
83: mpz_fdiv, with the exception that some of the new functions return useful
84: values.
85:
86: The old function names can still be used. All the old functions names will
87: now do floor division, not trunc division as some of them used to. This was
88: changed to make the functions more compatible with common mathematical
89: practice.
90:
91: The mpz_mod and mpz_mod_ui functions now compute the mathematical mod
92: function. I.e., the sign of the 2nd argument is ignored.
93:
94: * The mpq assignment functions do not canonicalize their results. A new
95: function, mpq_canonicalize must be called by the user if the result is not
96: known to be canonical.
97: * The mpn functions are now documented. These functions are intended for
98: very time critical applications, or applications that need full control over
99: memory allocation. Note that the mpn interface is irregular and hard to
100: use.
101: * New functions for arbitrary precision floating point arithmetic. Names
102: begin with `mpf_'. Associated type mpf_t.
103: * New and improved mpz functions, including much faster GCD, fast exact
104: division (mpz_divexact), bit scan (mpz_scan0 and mpz_scan1), and number
105: theoretical functions like Jacobi (mpz_jacobi) and multiplicative inverse
106: (mpz_invert).
107: * New variable types (mpz_t and mpq_t) are available that makes syntax of
108: mpz and mpq calls nicer (no need for & before variables). The MP_INT and
109: MP_RAT types are still available for compatibility.
110: * Uses GNU configure. This makes it possible to choose target architecture
111: and CPU variant, and to compile into a separate object directory.
112: * Carefully optimized assembly for important inner loops. Support for DEC
1.1.1.2 maekawa 113: Alpha, Amd 29000, HPPA 1.0 and 1.1, Intel Pentium and generic x86, Intel
1.1 maekawa 114: i960, Motorola MC68000, MC68020, MC88100, and MC88110, Motorola/IBM
115: PowerPC, National NS32000, IBM POWER, MIPS R3000, R4000, SPARCv7,
116: SuperSPARC, generic SPARCv8, and DEC VAX. Some support also for ARM,
117: Clipper, IBM ROMP (RT), and Pyramid AP/XP.
118: * Faster. Thanks to the assembler code, new algorithms, and general tuning.
119: In particular, the speed on machines without GCC is improved.
120: * Support for machines without alloca.
121: * Now under the LGPL.
122:
123: INCOMPATIBILITIES BETWEEN GMP 1 AND GMP 2
124:
125: * mpq assignment functions do not canonicalize their results.
126: * mpz division functions round differently.
127: * mpz mod functions now really compute mod.
128: * mpz_powm and mpz_powm_ui now really use mod for reduction.
