--- Comment #1 from John David Anglin <danglin at gcc dot gnu.org> ---
The following fails are also probably related:

FAIL: math/basic-test
FAIL: math/test-double-canonicalize
FAIL: math/test-float-canonicalize
FAIL: math/test-idouble-canonicalize
FAIL: math/test-ifloat-canonicalize

The basic-test fail is related to the treatment of signaling nans during
conversion:

dave@mx3210:~/gnu/glibc/objdir/math$ cat basic-test.out
Failure:  double x = (double) (long double) sNaN, !issignaling
Failure:  long double x = (long double) (double) sNaN, !issignaling

I filed a gcc bug report:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81120

However, as noted in the above, there are subtle issues involving the
conversion
of signaling nans.
