From 4988e26b94a9397d934e43f9116b0d33b3a454b2 Mon Sep 17 00:00:00 2001 From: Zack Weinberg Date: Wed, 8 Jan 2020 14:28:23 -0500 Subject: [PATCH] MIPS: Fix circular definition of __LDBL_MANT_DIG__ in ieee754.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In commit aa706e13f4bfdf32a27c498902edf4f6006e433e, sysdeps/mips/ieee754/ieee754.h was changed to use GCC’s predefined macro __LDBL_MANT_DIG__, instead of including and using LDBL_MANT_DIG (and therefore polluting the user namespace with all of the macros defined in float.h). In order to support compilers that don’t provide __LDBL_MANT_DIG__, there is a fallback #if block which was supposed to include and then define __LDBL_MANT_DIG__ to LDBL_MANT_DIG. However, at some point during the development of the patch, a typo was introduced, causing the fallback block to define __LDBL_MANT_DIG__ to expand to __LDBL_MANT_DIG__. Correct this typo. --- sysdeps/mips/ieee754/ieee754.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sysdeps/mips/ieee754/ieee754.h b/sysdeps/mips/ieee754/ieee754.h index 75059f733b..62f17586f1 100644 --- a/sysdeps/mips/ieee754/ieee754.h +++ b/sysdeps/mips/ieee754/ieee754.h @@ -24,7 +24,7 @@ #ifndef __LDBL_MANT_DIG__ # include -# define __LDBL_MANT_DIG__ __LDBL_MANT_DIG__ +# define __LDBL_MANT_DIG__ LDBL_MANT_DIG #endif __BEGIN_DECLS
