Well, there's an argument against it, all right, but the view that it's

appears to be a minority one. It's clear that quite a few people find
such
transformations useful. Those of you who want standard-conforming
behavior
don't have to use -ffast-math, after all.
OR, those who do not want standard conforming code probably ought to be
using -ffast-math. I *much* prefer to keep the compiler standards conforming.

I think there is general agreement on that (without -ffast-math). But Fariborz's change is done only with flag_unsafe_math_optimizations.



Yes. Just as many other transformations that are being done in the same routine.
