From 1c09524e4db3efd797ebcfcd8241bdb78f0b06f0 Mon Sep 17 00:00:00 2001 From: Tulio Magno Quites Machado Filho Date: Wed, 6 Jun 2018 12:27:39 -0300 Subject: powerpc64le: Fix TFtype in sqrtf128 when using -mabi=ieeelongdouble When building with -mlong-double-128 or -mabi=ibmlongdouble, TFtype represents the IBM 128-bit extended floating point type, while KFtype represents the IEEE 128-bit floating point type. The soft float implementation of e_sqrtf128 had to redefine TFtype and TF in order to workaround this issue. However, this behavior changes when -mabi=ieeelongdouble is used and the macros are not necessary. * sysdeps/powerpc/powerpc64/le/fpu/e_sqrtf128.c [__HAVE_FLOAT128_UNLIKE_LDBL] (TFtype, TF): Restrict TFtype and TF redirection to KFtype and KF only when the default long double type is not the IEEE 128-bit floating point type.
