Subject: Use libm_alias_ldouble for SPARC fabsl.
X-Git-Tag: glibc-2.27~696
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=006e766437033d6565133ce356b55d7b301a7b58;p=thirdparty%2Fglibc.git

Use libm_alias_ldouble for SPARC fabsl.

This patch makes SPARC fabsl implementation use libm_alias_ldouble, to
prepare them for also defining _Float128 function aliases.

Tested with build-many-glibcs.py that installed stripped shared
libraries (sparc64-linux-gnu and sparcv9-linux-gnu) are unchanged by
the patch.

	* sysdeps/sparc/sparc32/fpu/s_fabsl.c: Include
	<libm-alias-ldouble.h>.
	(fabsl): Define using libm_alias_ldouble.
	* sysdeps/sparc/sparc64/fpu/s_fabsl.c: Include
	<libm-alias-ldouble.h>.
	(fabsl): Define using libm_alias_ldouble.
