Re: [Open64-devel] Fix to bug 917

My understanding is that the simplifier gets invoked by calling WN_CreateExp[0123] instead of WN_CreateExp[0123].

The BE uses the same const fold in simplifier. I think there is a way
to include simplifier in fortran FE. My question is, are you using
that? Or writing your own? If you are writing your own, I just want to
point out the potential problems in terms of rounding/... IEEE issue
