GCC Spec2017 optimization Wiki

[Tamar Christina]

Hi Thomas,

In general our approach is to identify areas for improvement in a benchmark and provide a testcase that's independent of the benchmark when reporting it in a PR upstream.

This simplifies the problem and also allows people who don't have access to SPEC to contribute. Of course this is not always do-able but for a large part of the cases so far this has worked out well.

So I think that's the best way to handle the Fortran and other benchmarks.  For the bigger work items we may need to find an alternative.

Cheers,
Tamar

A few of them are written in Fortran.  As SPEC is closed source and costs are quite high, none of the gfortran maintainers (who are all volunteers) is in a position to contribute.

Any ideas how to do anything about that?
