From 79850e1025aabeccd3586c32ca259aa854607582 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 29 Sep 2021 17:38:32 +0000 Subject: [PATCH] Do not define tgmath.h fmaxmag, fminmag macros for C2X (bug 28397) C2X does not include fmaxmag and fminmag. When I updated feature test macro handling accordingly (commit 858045ad1c5ac1682288bbcb3676632b97a21ddf, "Update floating-point feature test macro handling for C2X", included in 2.34), I missed updating tgmath.h so it doesn't define the corresponding type-generic macros unless __STDC_WANT_IEC_60559_BFP_EXT__ is defined; I've now reported this as bug 28397. Adjust the conditionals in tgmath.h accordingly. Tested for x86_64. --- math/tgmath.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/math/tgmath.h b/math/tgmath.h index 9868353c463..3d7b0998df3 100644 --- a/math/tgmath.h +++ b/math/tgmath.h @@ -921,7 +921,9 @@ /* Like ilogb, but returning long int. */ # define llogb(Val) __TGMATH_UNARY_REAL_RET_ONLY (Val, llogb) +#endif +#if __GLIBC_USE (IEC_60559_BFP_EXT) /* Return value with maximum magnitude. */ # define fmaxmag(Val1, Val2) __TGMATH_BINARY_REAL_ONLY (Val1, Val2, fmaxmag) -- 2.39.2
