--- Comment #2 from Ed Maste <emaste at freebsd.org> ---
To be clear, this is not a compiler bug: floatdidf comes from an assembly
routine in compiler-rt/lib/builtins/i386/floatdidf.S. I see there is a generic
C version in compiler-rt/lib/builtins/floatdidf.c that we might be able to use,
although preferably using the optimized one (via ifunc or such) when possible.
