Fix priority of >> vs +. * math/libm-test.c (basic_tests): Use the appropriate isnan and isinf function to test the value of the nan function. 1997-04-15 13:40 Ulrich Drepper <drepper@cygnus.com> * sysdeps/libm-i387/s_finite.S: Fix typo. * sysdeps/i386/fpu/__math.h: Add optimized versions of isgreater, isgreaterequal, isless, islessequal, islessgreater, and isunordered.
