[BZ #4096]
2007-03-01 Jakub Jelinek <jakub@redhat.com> [BZ #4096] * sysdeps/ieee754/dbl-64/e_pow.c (__ieee754_pow): Check for NaN earlier. * math/libm-test.inc (pow_test): Add more tests involving NaNs. * sysdeps/i386/fpu/e_powf.S (__ieee754_powf): Avoid invalid exception for x qNaN and y either +-inf or non-integer value. * sysdeps/i386/fpu/e_pow.S (__ieee754_pow): Likewise. * sysdeps/i386/fpu/e_powl.S (__ieee754_powl): Likewise. * sysdeps/x86_64/fpu/e_powl.S (__ieee754_powl): Likewise.
