From: "Gabriel F. T. Gomes" <gabriel@inconstante.eti.br> The functions in the nexttoward family are special, in the sense that they always have a long double argument, regardless of their suffix (i.e.: nexttowardf and nexttoward have a long double argument, besides the float and double arguments). On top of that, they are also special because nexttoward functions are not part of the _FloatN API, hence __nexttowardf128 do not exist. This patch adds 4 new function implementations for the new long double format: __nexttoward_to_ieee128 __nexttowardf_to_ieee128 __nexttowardieee128 (as an alias to __nextafterieee128) 2018-06-19 Gabriel F. T. Gomes <gabriel@inconstante.eti.br> Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com> * sysdeps/ieee754/ldbl-128ibm-compat/Versions: Add __nexttowardf_to_ieee128, __nexttowardieee128 and __nexttoward_to_ieee128. * sysdeps/ieee754/ldbl-128ibm-compat/s_nextafterf128.c: New file. * sysdeps/ieee754/ldbl-128ibm-compat/s_nexttowardf128.c: New file. --- sysdeps/ieee754/ldbl-128ibm-compat/Versions | 3 ++ .../ieee754/ldbl-128ibm-compat/s_nextafterf128.c | 20 ++++++++++++ .../ieee754/ldbl-128ibm-compat/s_nexttowardf128.c | 38 ++++++++++++++++++++++ 3 files changed, 61 insertions(+) create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/s_nextafterf128.c create mode 100644 sysdeps/ieee754/ldbl-128ibm-compat/s_nexttowardf128.c
