It way for each platform to inline the isnan, isinf, finite, etc test in the libm function wrappers (i.e w_pow.c) Is uses macros defined in math-private.h to inline the various (redundent) tests required to set errno (if needed). The generic ./math/math_private.h maintains the status quo, but a platform can override math_private.h to define macros that work best for them. -- http://sourceware.org/bugzilla/show_bug.cgi?id=6406 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
