--- Comment #4 from Florian Weimer <fw at gcc dot gnu.org> ---
Does -mieee-fp still impact code generation on i386?  What about x86-64 with
SSE2?

I would expect that existing users of -mieee-fp receive an error when they
compile and link with a upgraded glibc, so I don't think the missing archive is
necessarily a problem we need to fix.

However, if there is no way to request the code generator to change behavior,
then we have a problem.
