This directory contains 'mbench', a program written by Patrick PĂ©lissier
(INRIA) to bench MPFR for low precisions.
It is distributed under the terms of the GNU Lesser General Public License as
published by the Free Software Foundation; either version 3 of the License,
or (at your option) any later version.
To use the mbench program:
Build it:
make GMP=/dir/to/gmp MPFR=/dir/to/mpfr
Run it by specifying the functions you want to bench:
./mfv5 mpfr_add mpfr_mul mpfr_sub mpfr_div mpfr_sqrt
To have the lists of the available functions:
./mfv5 -l
Help usage:
./mfv5 -h
To build MFV5 with PARI/NTL/CLN/MAPM/ARPREC/CRLIBM support, build it with:
make GMP=/dir/to/gmp MPFR=/dir/to/mpfr PARI=/dir/to/pari ...
(It autodetects which library is available.)
Then use ./mfv5 -l to have the lists of the available functions.
To add a new function in MPFR (mpfr_toto), edit mfv5-mpfr.cc and add:
class mpfr_toto_test {
public:
int func (mpfr_ptr a, mpfr_srcptr b, mpfr_srcptr c, mp_rnd_t r) {
return mpfr_toto (a,b,r);
}
};
static mpfr_test<mpfr_toto_test> testtoto ("mpfr_toto");
Rebuild it and that's all.
