This directory contains 'mbench', a program written by Patrick Pélissier

(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. Thus a non-existent directory

can be given to disable a library installed on the system if it yields a

build failure.)

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.
