GLOBAL_IEEE754_END(log2l)
Use libm_alias_ldouble macros in sysdeps/ia64/fpu. Continuing the preparation for additional _FloatN / _FloatNx aliases, this patch makes long double functions in sysdeps/ia64/fpu use libm_alias_ldouble macros, so that they can have _Float64x aliases added in future. Most ia64 libm functions are defined using ia64-specific macros in libm-symbols.h. These are left unchanged, with libm-alias-ldouble.h included from libm-symbols.h (and the expectation that other libm-alias-*.h headers will be included from there as well in future), and libm_alias_ldouble_other then being used in most cases to define aliases for any additional types (currently the empty set). Functions that used weak_alias are converted to use libm_alias_ldouble. Tested (compilation only) with build-many-glibcs.py for ia64, including that installed stripped shared libraries are unchanged by the patch. * sysdeps/ia64/fpu/libm-symbols.h: Include <libm-alias-ldouble.h>. * sysdeps/ia64/fpu/e_acoshl.S (acoshl): Use libm_alias_ldouble_other. * sysdeps/ia64/fpu/e_acosl.S (acosl): Likewise. * sysdeps/ia64/fpu/e_asinl.S (asinl): Likewise. * sysdeps/ia64/fpu/e_atanhl.S (atanhl): Likewise. * sysdeps/ia64/fpu/e_coshl.S (coshl): Likewise. * sysdeps/ia64/fpu/e_exp10l.S (exp10l): Likewise. * sysdeps/ia64/fpu/e_exp2l.S (exp2l): Likewise. * sysdeps/ia64/fpu/e_fmodl.S (fmodl): Likewise. * sysdeps/ia64/fpu/e_hypotl.S (hypotl): Likewise. * sysdeps/ia64/fpu/e_lgammal_r.c (lgammal_r): Define using libm_alias_ldouble_r. * sysdeps/ia64/fpu/e_log2l.S (log2l): Use libm_alias_ldouble_other. * sysdeps/ia64/fpu/e_logl.S (logl): Likewise.
