Continuing the process of setting up common macros for libm function aliases, with a view to using them to define _FloatN / _FloatNx aliases in future, this patch adds a libm_alias_ldouble macro and uses it in the type-generic templates. Since math-type-macros-ldouble.h already did the appropriate thing for each symbol (weak_alias or long_double_symbol), this is just a straightforward rearrangement of code, to make the required logic available in a place that can also be used outside of the type-generic templates in future (in particular, to eliminate various wrappers for functions in ldbl-opt and ldbl-64-128). Tested for x86_64. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/libm-alias-ldouble.h: New file. * sysdeps/ieee754/ldbl-opt/libm-alias-ldouble.h: Likewise. * sysdeps/ieee754/ldbl-opt/math-type-macros-ldouble.h: Remove. * sysdeps/generic/math-type-macros-ldouble.h: Include <libm-alias-ldouble.h>. [!declare_mgen_alias] (declare_mgen_alias): Define to use libm_alias_ldouble.
