Simplify the C99 isgreater macros. Although some support was added in GCC 2.97, not all targets added support until GCC 3.1. Therefore only use the builtins in math.h from GCC 3.1 onwards, and defer to generic macros otherwise. Improve the generic isunordered macro to use compares rather than call fpclassify twice - this is not only faster but also correct for signaling NaNs. * math/math.h: Improve handling of C99 isgreater macros. * sysdeps/alpha/fpu/bits/mathinline.h: Remove isgreater macros. * sysdeps/m68k/m680x0/fpu/bits/mathinline.h: Likewise. * sysdeps/powerpc/bits/mathinline.h: Likewise. * sysdeps/sparc/fpu/bits/mathinline.h: Likewise. * sysdeps/x86/fpu/bits/mathinline.h: Likewise. |
