From 976e9d281b2900f988e14ef541b5716dbdd4849e Mon Sep 17 00:00:00 2001 From: Jeff Johnston Date: Thu, 26 Apr 2007 19:23:37 +0000 Subject: 2007-04-26 Patrick Mansfield * libc/include/ieeefp.h: use prefixed __ieeefp_ macros that can be overridden via machine/ieeefp.h. * libc/include/machine/ieeefp.h: Add SPU specific C99 and ieeefp macros for isnan and related macros. * libc/include/math.h: Allow C99 isfinite, isinf, and isnan to be overridden via machine/ieeefp.h. * libm/machine/spu/Makefile.am: Add new files. * libm/machine/spu/Makefile.in: Autogenerate with new files. * libm/machine/spu/sf_fpclassify.c: Add SPU specific __fpclassifyf. * libm/machine/spu/sf_finite.c: Add SPU specific finitef. * libm/machine/spu/sf_isinf.c: Add SPU specific isinff. * libm/machine/spu/sf_isinff.c: Add SPU specific __isinff. * libm/machine/spu/sf_isnan.c: Add SPU specific isnanf. * libm/machine/spu/sf_isnanf.c: Add SPU specific __isnanf. * libm/machine/spu/sf_nan.c: Add SPU specific nanf. --- newlib/libc/include/math.h | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'newlib/libc/include/math.h') diff --git a/newlib/libc/include/math.h b/newlib/libc/include/math.h index 3e96757c8..63cc99286 100644 --- a/newlib/libc/include/math.h +++ b/newlib/libc/include/math.h @@ -131,21 +131,29 @@ extern int __signbitd (double x); (__extension__ ({__typeof__(x) __x = (x); \ (sizeof (__x) == sizeof (float)) ? __fpclassifyf(__x) : __fpclassifyd(__x);})) +#ifndef isfinite #define isfinite(y) \ (__extension__ ({__typeof__(y) __y = (y); \ fpclassify(__y) != FP_INFINITE && fpclassify(__y) != FP_NAN;})) +#endif /* Note: isinf and isnan were once functions in newlib that took double * arguments.
