This patch continues the preparation for additional _FloatN / _FloatNx function aliases by using libm_alias_ldouble for sysdeps/x86_64/fpu long double functions, so that they can have _Float64x aliases added in future. Tested for x86_64, including build-many-glibcs.py tests that installed stripped shared libraries are unchanged by the patch. * sysdeps/x86_64/fpu/e_expl.S: Include <libm-alias-ldouble.h>. [USE_AS_EXPM1L] (expm1l): Define using libm_alias_ldouble. * sysdeps/x86_64/fpu/s_ceill.S: Include <libm-alias-ldouble.h>. (ceill): Define using libm_alias_ldouble. * sysdeps/x86_64/fpu/s_copysignl.S: Include <libm-alias-ldouble.h>. (copysignl): Define using libm_alias_ldouble. * sysdeps/x86_64/fpu/s_fabsl.S: Include <libm-alias-ldouble.h>. (fabsl): Define using libm_alias_ldouble. * sysdeps/x86_64/fpu/s_floorl.S: Include <libm-alias-ldouble.h>. (floorl): Define using libm_alias_ldouble. * sysdeps/x86_64/fpu/s_fmaxl.S: Include <libm-alias-ldouble.h>. (fmaxl): Define using libm_alias_ldouble. * sysdeps/x86_64/fpu/s_fminl.S: Include <libm-alias-ldouble.h>. (fminl): Define using libm_alias_ldouble. * sysdeps/x86_64/fpu/s_llrintl.S: Include <libm-alias-ldouble.h>. (llrintl): Define using libm_alias_ldouble. (lrintl): Likewise. * sysdeps/x86_64/fpu/s_nearbyintl.S: Include <libm-alias-ldouble.h>. (nearbyintl): Define using libm_alias_ldouble. * sysdeps/x86_64/fpu/s_truncl.S: Include <libm-alias-ldouble.h>. (truncl): Define using libm_alias_ldouble. * sysdeps/x86_64/x32/fpu/s_lrintl.S: Include <libm-alias-ldouble.h>. (lrintl): Define using libm_alias_ldouble.
