Update.
2001-06-14 Roland McGrath <roland@frob.com> * configure.in: Let sysdeps Implies files in add-ons bring in sysdeps directories from the main source and other add-ons too. 2001-06-15 Jakub Jelinek <jakub@redhat.com> * math/test-misc.c (main): Add tests for nextafter and nexttoward with +-Inf as second argument. * sysdeps/generic/s_nexttowardf.c (__nexttowardf): Only check for NaN, not Inf. * sysdeps/i386/fpu/s_nextafterl.c (__nextafterl): Fix check for NaN. * sysdeps/i386/fpu/s_nexttoward.c: New. * sysdeps/i386/fpu/s_nexttowardf.c: New. * sysdeps/ieee754/ldbl-96/s_nexttoward.c (__nexttoward): Simplify check for NaN, optimize x==+-0 handling. * sysdeps/ieee754/ldbl-96/s_nexttowardf.c (__nexttowardf): Likewise. * sysdeps/ieee754/ldbl-96/s_nextafterl.c (__nextafterl): Simplify check for NaN, fix sign in x==+-0 case. * sysdeps/ia64/fpu/s_nexttoward.c: New. * sysdeps/ia64/fpu/s_nexttowardf.c: New. 2001-06-15 H.J. Lu <hjl@gnu.org> * rt/tst-aio2.c (do_test): Initialize cb.aio_offset to 0. * rt/tst-aio3.c (do_test): Likewise. * rt/tst-aio4.c (do_test): Likewise. * rt/tst-aio5.c (do_test): Likewise. * rt/tst-aio6.c (do_test): Likewise.
