cd60c4c9f9 [CI SKIP] Disable multiprecision in certain compilers. 2018-10-29 08:52:20 -06:00
Andrey Semashev
7c5def9d39 Disable Boost.Multiprecision tests for gcc 4.7 in C++11 mode. 
The compiler fails in Boost.TypeTraits which is used in Boost.Multiprecision.

791a139a51 Disable testing C++14 and 17 on clang 3.8 and 3.9. 
The compiler uses libstdc++ from gcc 4.8, which does not support C++14.
In particular, it is trying to import the missing ::gets function.

835ac98a23 Fail libgmpxx detection on Linux if libstdc++ is not used as the std library. 
libgmpxx was built against libstdc++, so if the application uses e.g. libc++,
linking fails because of the standard symbols mismatch.

e0646cb7ec Add template argument to green up build. Remove discrete log as we do not have an overflow-resistant mul_mod in boost. 2018-10-26 16:58:30 -06:00

2d463f3ee7 a*p % m may overflow, do not perform naive multiplication in unit tests or undefined behavior may result. [CI SKIP] 2018-10-26 11:19:43 -06:00

3f1603938c Revert change as the previous algorithm overflows for all inputs >= half the bit length of the type. 2018-10-25 18:05:14 -06:00

54d0e4c63e [ci skip] Trade out algorithm from 'The Joy of Factoring' to Wikipedia's version which reduces the number of required temporaries. In fact, the speedup is not large, but the code is more compact, and for larger types, the difference becomes more noticeable. 2018-10-25 14:28:39 -06:00
Nick Thompson
87e5b365d8 Return custom struct from extended Euclidean algorithm rather than tuple. Reduce number of operations for tests to reduce CI system workload. Disable discrete log tests until we have time to figure out why they are failing. 2018-10-25 09:38:16 -06:00
Nick Thompson
ada03a59d7 Remove dependency on boost.format, remove unfettered use of auto in order to move towards C++03 compatibility, use BOOST_THROW_EXCEPTION. 2018-10-24 14:29:22 -06:00

faa61cd911 [ci skip] It is *not* the case that a discrete log exists when the base and modulus are coprime. Take 4^x = 2 mod 5 as a counterexample. Change API accordingly. 2018-02-10 17:51:59 -06:00

Nick Thompson
b3966428c4 [ci skip] Add test of short int to see if there's any obvious places for overflow (none are obvious, but no guarantees they still aren't there). Print basic information about the test to console so that failures are easier to track down. 2018-02-10 13:56:11 -06:00
Nick Thompson
8c415f77b1 [ci skip] Use less verbose naming. Add asserts as verfication of algorithms is a negligible fraction of total runtime. Use boost::multiprecision::powm and boost::multiprecision::sqrt rather than one-offs. 2018-02-09 17:19:26 -06:00

Correct make_odd return type inconsistency
 2017-08-27 12:07:50 -04:00
Andrey Semashev
bc2349f71b Corrected make_odd return type inconsistency. 
Make gcd_traits<signed char>::make_odd return unsigned int, similar to all other gcd_traits specializations. Also, correct the local variable types that receive the result of make_odd to avoid warnings about unintended conversion.
