--- Comment #1 from Joseph Myers <jsm28 at gcc dot gnu.org> ---
Similar issues apply for x86_64 powl as well, including cases where the error
is in the other direction, e.g.:
Failure: Test: pow_downward (-0x2p+0, 0x1.fffffffffffffp+52)
Result:
is: -1.18973149535723176503e+4932 -0xf.fffffffffffffff00000p+16380
should be: -inf -inf
