Daniel Mendler b800b761 2019-11-22T16:04:48 remove *_ll* setters/getters * they are non standard * they are incompatible with older compilers * u64/i64 functions should be used instead * these functions should be deprecated again in 1.x
Daniel Mendler f6a7bedb 2019-10-29T20:52:29 suffix _u32 -> _n of mp_(expt|log|root) functions, use int for now

Daniel Mendler bf9507a9 2019-10-24T22:02:29 replace mp_bool by stdbool * This gives the advantage that static analysis **understands** bool, but complains about using an enum type instead of bool. * If stdbool.h is not desired, true/false/bool can be replaced using sed as in the no-stdint-h branch. * We already include stdint.h and stdbool.h is not more harmful than this header

Daniel Mendler 71696549 2019-05-29T20:36:18 deprecate mp_expt_d and mp_n_root in favor of mp_expt and mp_root
Joachim Breitner 6c35dd7e 2019-07-15T12:15:10 Import stddef in tommath.h At least here (compiling for WebAssembly (`wasm32-unknown-unknown-wasm`), I need this, otherwise `size_t` is not available.

Francois Perrad 25ff85d2 2019-05-23T18:00:21 move cast inside macro
Daniel Mendler c7314fa4 2019-05-25T06:42:01 deprecate mp_n_root_ex and mp_expt_d_ex These functions were introduced to give some timing guarantees. However the guarantees are too weak to be useful. The functions seem to be unused essentially by downstream users.
Daniel Mendler 4b475aca 2019-05-26T09:29:58 fixes for msvc
Daniel Mendler bcec605a 2019-05-22T15:34:49 deprecate mp_prime_is_divisible and ltm_prime_tab * it is an implementation detail used for prime testing * there is upcoming work by @czurnieden regarding a generalised prime sieve * furthermore remove jacobi test (replaced by kronecker)
Daniel Mendler c7a7bd47 2019-05-23T16:37:34 MP_PREC is an internal macro, it should be defined in tommath_private.h
Daniel Mendler b0938d70 2019-05-24T11:48:27 remove obsolete comment
Daniel Mendler 9f607dd5 2019-05-23T17:00:47 disallow defining MP_DIGIT_BIT, only allow MP_8/16/31/32/64BIT
Daniel Mendler 0a9f5e9b 2019-05-24T10:21:54 use u32 i64 suffix
Daniel Mendler d7e1cb4a 2019-05-24T00:15:11 another proposal: use _ul and _l for the long macros
Daniel Mendler b58c9966 2019-05-23T23:39:47 use int32 and uint32 instead of sint and uint
Daniel Mendler d7959854 2019-05-23T11:12:30 improve comment in tommath.h, extend .gitignore
Daniel Mendler 3289c959 2019-05-20T10:41:06 introduce various mp_set_sint/mp_set_uint functions with precise types
Daniel Mendler 1af0de1f 2019-05-20T19:11:25 deprecate mp_tc_(and|or|xor) in favor of mp_(and|or|xor) * same behavior for positive numbers * generalisation for negative numbers, treating them as two complement * improve algorithm, iterate once over the digits, manually perform two complement * simplify mp_add_d, mp_sub_d * functions are safe in case of a==c or b==c * renamed mp_tc_div_2d to mp_signed_rsh (signed right shift)
Daniel Mendler 0dfa9da5 2019-05-19T12:53:49 make tommath_class.h and tommath_superclass.h private These headers are used for configuration during build time. Therefore they shouldn't be exposed as part of the public API.
Daniel Mendler 0b840b78 2019-05-17T20:53:24 make mp_word private mp_word is an internal type and it is problematic if it is exposed in the public api. See for example #216 - MSVC does not support 128 bit mp_words. But it is perfectly ok to use those internally in the library, as long as the library is compiled with GCC.
Daniel Mendler a8239c24 2019-05-13T11:32:42 deprecate mp_get_bit The return type of mp_get_bit was imprecise (either mp_err or mp_bool), therefore this function is deprecated in favor of s_mp_get_bit for now. If we need s_mp_get_bit to be public, we should add it under a different name. However since mp_set_bit is not available, I don't think there any downstream users (ab)using mp_int as bitsets.
Daniel Mendler 56e7a401 2019-05-13T02:46:11 deprecate mp_jacobi
Daniel Mendler 89bac3a7 2019-05-13T15:06:54 deprecate MP_RANGE
Daniel Mendler 4534056c 2019-05-13T00:22:18 use enums mp_err, mp_ord, mp_bool, mp_sign * MP_USE_ENUMS enables enums * Wc++-compat catches some implicit conversions if MP_USE_ENUMS is defined * 100% backwards compatible API/ABI if MP_USE_ENUMS is not defined
Francois Perrad 38116079 2019-05-13T17:51:07 literal suffix
Francois Perrad 2d508723 2019-05-13T17:36:12 const parameter
Daniel Mendler 7365442a 2019-05-10T23:59:46 No grow necessary in mp_set_int* functions * mp_set_int* always return MP_OKAY * remove return checks for mp_set_int* * introduce MP_MIN_PREC
Daniel Mendler adf9605d 2019-05-09T03:28:49 add warn_unused_result, found one missing check!
Francois Perrad cc703a84 2019-05-11T12:09:59 add missing parameter name in prototype
Daniel Mendler 0669e92e 2019-05-08T20:18:53 deprecate mp_prime_random_ex in favor of mp_prime_rand We can use the internal mp_rand generator now, since it generates numbers which are safe for crypto purposes.
Daniel Mendler e05215a8 2019-05-09T04:06:12 deprecate old macros, deprecate mp_rand_digit
Daniel Mendler 9ddf1e58 2019-05-07T12:26:46 support custom random data source via mp_rand_source * deprecate MP_PRNG_ENABLE_LTM_RNG * custom mp_rand_source is used always if set, which should be more aligned with user expectations * use custom source in tune.c * don't call random number generator once per digit, which is slow
Daniel Mendler 290c28c1 2019-05-07T09:49:26 deprecate PRIME_SIZE in favor of MP_PRIME_SIZE
Daniel Mendler 44d03a6f 2019-05-07T09:45:38 deprecate LTM_PRIME_* macros in favor of MP_PRIME_*
Daniel Mendler e2ee39b5 2019-04-26T12:39:26 deprecate ltm_prime_callback
Daniel Mendler 80f5fac5 2019-04-26T12:35:39 rename LTM_NO_FILE to MP_NO_FILE
Daniel Mendler 0337d48b 2019-04-25T19:35:19 add MP_NULL_TERMINATED
Daniel Mendler 250751be 2019-05-07T09:32:59 tommath.h: do not expose stdlib.h
Daniel Mendler 818d8fb7 2019-05-03T17:39:10 Rework handling of tunable cutoffs * In the default settings, a cutoff X can be modified at runtime by adjusting the corresponding X_CUTOFF variable. * Tunability of the library can be disabled at compile time by defining the MP_FIXED_CUTOFFS macro. * There is an additional file tommath_cutoffs.h, which defines the default cutoffs. These can be adjusted manually or by the autotuner.
Daniel Mendler 90eccd57 2019-04-25T15:36:35 prefix private macros by PRIVATE_
Daniel Mendler 632601f4 2019-04-13T17:34:11 MP_WARRAY is an internal macro
Daniel Mendler e45f75fd 2019-04-13T08:46:57 deprecate DIGIT_BIT, use MP_DIGIT_BIT
Daniel Mendler a8c76138 2019-04-12T21:15:56 deprecate macros in tommath.h * move MP_DEPRECATED to tommath.h since we need it later * add MP_DEPRECATED_PRAGMA
Daniel Mendler 87292ed1 2019-04-09T12:19:40 move mp_balance_mul to tommath_private.h

Daniel Mendler 70a30ae7 2019-04-07T02:29:28 remove footers
Daniel Mendler 5da4e0ac 2019-04-04T23:06:00 remove unnecessary size_t casts, fix Wconversion/Wsign-conversion issues Wconversion and Wsign-conversion is still not activated by default, since there are many issues in demo.c.
czurnieden 769218cc 2019-04-03T18:59:09 additional functions mp_incr and mp_decr
