This patch adds support for running libm tests for float128 in the case where the float128 functions are aliases of long double functions. In this case, the sysdeps Makeconfig file (i.e. sysdeps/ieee754/ldbl-128/Makeconfig) will need to define "float128-alias-fcts = yes" to enable the tests. Tested for x86_64. Also tested with build-many-glibcs.py; installed stripped shared libraries are unchanged by the patch. Also tested together with changes to enable the float128 aliases. * math/Makefile (test-types): Add $(type-float128-$(float128-alias-fcts)). * math/test-float128.h (TYPE_STR): Define conditional on [FLT128_MANT_DIG == LDBL_MANT_DIG]. (ULP_IDX): Likewise. (ULP_I_IDX): Likewise.
