From 722e363c4de410e67f24d0da3129c446074716bc Mon Sep 17 00:00:00 2001 From: Yaakov Selkowitz Date: Mon, 4 Apr 2016 14:13:21 -0500 Subject: math: guard BSD finite/isinf/isnan functions properly in math.h Now that we have properly functioning feature test macros, the BSD floating-point classification functions can go into math.h instead of the non-standard ieeefp.h, and not under the C99 guard: http://man7.org/linux/man-pages/man3/finite.3.html The isnan function was in earlier versions of SUS but removed starting with POSIX.1-2001, compare: http://pubs.opengroup.org/onlinepubs/007908799/xsh/math.h.html http://pubs.opengroup.org/onlinepubs/009695399/basedefs/math.h.html Note that the isinf and isnan functions (but not the variants) conflict with functions by the same name in C++11, hence they (and only they) need to be hidden: https://sourceware.org/git/?p=glibc.git;a=commit;h=d9b965fa56350d6eea9f7f438a0714c7ffbb183f https://sourceware.org/git/?p=glibc.git;a=commit;h=3c47c83a9730c20e602694505b9278c25637b0d0 Signed-off-by: Yaakov Selkowitz --- newlib/libc/include/ieeefp.h | 13 ------------- 1 file changed, 13 deletions(-) (limited to 'newlib/libc/include/ieeefp.h') diff --git a/newlib/libc/include/ieeefp.h b/newlib/libc/include/ieeefp.h index 2ffa456bb..2c042848b 100644 --- a/newlib/libc/include/ieeefp.h +++ b/newlib/libc/include/ieeefp.h @@ -241,19 +241,6 @@ typedef int fp_rdi; fp_rdi _EXFUN(fpgetroundtoi,(void)); fp_rdi _EXFUN(fpsetroundtoi,(fp_rdi)); -#undef isnan -#undef isinf - -int _EXFUN(isnan, (double)); -int _EXFUN(isinf, (double)); -int _EXFUN(finite, (double)); - - - -int _EXFUN(isnanf, (float)); -int _EXFUN(isinff, (float)); -int _EXFUN(finitef, (float)); - #define __IEEE_DBL_EXPBIAS 1023 #define __IEEE_FLT_EXPBIAS 127 -- cgit v1.2.3
