--- Comment #6 from joseph at codesourcery dot com <joseph at codesourcery =

The documentation of the source tree structure in maint.texi is rather out=
=20
of date, but the basic idea is that you have a header in sysdeps/generic=20
that defines an inline function doing a trivial direct conversion from=20
float to double and then a version of that header in sysdeps/riscv/rvd=20
that makes special use of copysign to preserve the sign of a NaN.
