Subject: Use libm_alias_double in ldbl-128, ldbl-96 fma.
X-Git-Tag: glibc-2.27~719
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f85a176f3f411b7478c2b8cb2708973e8668e7fb;p=thirdparty%2Fglibc.git

Use libm_alias_double in ldbl-128, ldbl-96 fma.

This patch makes the ldbl-128 and ldbl-96 implementations of fma use
libm_alias_double.

Tested for x86_64, and tested with build-many-glibcs.py that installed
stripped shared libraries are unchanged by the patch.

	* sysdeps/ieee754/ldbl-128/s_fma.c: Include <libm-alias-double.h>.
	[!__fma] (fma): Define using libm_alias_double.
	* sysdeps/ieee754/ldbl-96/s_fma.c: Include <libm-alias-double.h>.
	[!__fma] (fma): Define using libm_alias_double.
