Hi Andreas,

Yes that is possible, and that should remove all the annoying ULP file maintenance.
I think the maximum is 10 ULP currently, so if we accepted that for all math functions
then ULP testing would be almost useless. However we could set a target for each
function using a generic ULP file. Then the ULP checker would give a warning if the ULP
is larger (so each target generates a short list of cases that could be improved). If ULP is
larger than some maximum (which could be set per math function) you would get the
existing error.
Cheers,
Wilco
