Re: ERFC_SCALED compile-time simplification
I hope this is temporary and you will be working on getting this
and will remove this once GCC requires a new enough MPFR; MPFR has
more expertise on reviewing implementations of such functions and we'd
generally prefer to rely on their expertise rather than maintaining
That would be the better course, of course. I'd welcome such inclusion
into MPFR, would adapt gfortran accordingly (which would be trivial);
in the meantime, I'll file a feature request for MPFR.
Now, regarding me working to get this into MPFR, the thing is getting
it into gfortran and into MPFR have different requirements: MPFR
requires a proven, works-for-all-sizes algorithm, including correct
(and proven) bounds for the various domains, while for gfortran, all I
need is something that works for precisions implemented on GCC-
supported targets. While I am competent enough for the second one, the
scale of the first is outside my capabilities.
