From 8fed86556b7e162d2926f0ba6a573ed193ff882f Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Thu, 5 Nov 2015 17:00:31 +0000 Subject: Don't redirect ldexp to scalbn in bits/math-finite.h (bug 19209). bits/math-finite.h maps ldexp functions to corresponding scalbn functions. This is (a) a namespace bug for C90, which has ldexp but not scalbn, and (b) in any case useless, since the ldexp and scalbn functions have identical semantics (for floating-point types with radix 2), and since the fix for bug 6803 are actually aliases (presumably the mapping was based around the old bug of scalbn not setting errno). This patch removes the bogus redirections. Tested for x86_64 and x86. [BZ #19209] * math/bits/math-finite.h (ldexp): Remove declaration. (ldexpf): Likewise. (ldexpl): Likewise. --- math/bits/math-finite.h | 9 --------- 1 file changed, 9 deletions(-) (limited to 'math') diff --git a/math/bits/math-finite.h b/math/bits/math-finite.h index e5f11b2..5dd8406 100644 --- a/math/bits/math-finite.h +++ b/math/bits/math-finite.h @@ -413,15 +413,6 @@ extern long double __REDIRECT_NTH (log2l, (long double), __log2l_finite); # endif #endif -/* ldexp. */ -extern double __REDIRECT_NTH (ldexp, (double, int), scalbn); -#ifdef __USE_ISOC99 -extern float __REDIRECT_NTH (ldexpf, (float, int), scalbnf); -# ifdef __MATH_DECLARE_LDOUBLE -extern long double __REDIRECT_NTH (ldexpl, (long double, int), scalbnl); -# endif -#endif - /* pow. */ extern double __REDIRECT_NTH (pow, (double, double), __pow_finite); #ifdef __USE_ISOC99 -- cgit v1.1
