Subject: powerpc64le: Avoid conflicting types for f64xfmaf128 when IFUNC is not used
X-Git-Tag: glibc-2.35~494
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=54ff4f1e39067bfd04fb2141710637a11ef88862;p=thirdparty%2Fglibc.git

powerpc64le: Avoid conflicting types for f64xfmaf128 when IFUNC is not used

Avoid defining f64xfmaf128 twice when building s_fmaf128.c.
This can be reproduced on powerpc64le whenever f128 functions do not
have IFUNC enabled, e.g. using "--with-cpu=power8 --disable-multi-arch", or
when using "-with-cpu=power9".

Fixes: b3f27d8150d4f ("Add narrowing fma functions")
