Using time-critical floating-point features on a CPU-by-CPU basis is ok, but needs to be done with care. Are these instructions unconditionally available? Are they affected by a hardware state "rounding mode" which could make the operation incorrect? Using floating-point in C for something time-critical is not good since GMP should run well on a broad set of CPUs, some of which will run such code poorly. -- Torbjörn Please encrypt, key id 0xC8601622 _______________________________________________ gmp-devel mailing list gmp-devel@gmplib.org https://gmplib.org/mailman/listinfo/gmp-devel
