From 4680acecaac6a1bd2f8da06ed3e3403e8a66ed44 Mon Sep 17 00:00:00 2001 From: Christophe Lyon Date: Mon, 21 Sep 2020 15:22:30 +0000 Subject: [PATCH] libc/include/math.h: Remove parameter name As discussed in GCC bug 97088 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97088), parameters in prototypes of library functions should use reserved names, or no name at all. This patch removes the 'x' parameter name from extern int __isinff (float); extern int __isinfd (double); extern int __isnanf (float); extern int __isnand (double); extern int __fpclassifyf (float); extern int __fpclassifyd (double); extern int __signbitf (float); extern int __signbitd (double); to avoid possible clashes with user code in case someone uses before including Newlib's math.h (or uses some other conflicting definition) --- newlib/libc/include/math.h | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/newlib/libc/include/math.h b/newlib/libc/include/math.h index 5e6155c..ba1a8a1 100644 --- a/newlib/libc/include/math.h +++ b/newlib/libc/include/math.h @@ -201,14 +201,14 @@ extern int isnan (double); # define math_errhandling (_MATH_ERRHANDLING_ERRNO | _MATH_ERRHANDLING_ERREXCEPT) #endif -extern int __isinff (float x); -extern int __isinfd (double x); -extern int __isnanf (float x); -extern int __isnand (double x); -extern int __fpclassifyf (float x); -extern int __fpclassifyd (double x); -extern int __signbitf (float x); -extern int __signbitd (double x); +extern int __isinff (float); +extern int __isinfd (double); +extern int __isnanf (float); +extern int __isnand (double); +extern int __fpclassifyf (float); +extern int __fpclassifyd (double); +extern int __signbitf (float); +extern int __signbitd (double); /* Note: isinf and isnan were once functions in newlib that took double * arguments.
