T. Gomes <gabrielftg@linux.ibm.com> Date: Thu Jul 11 11:47:25 2019 -0300 ldbl-128ibm-compat: Add argp_error and argp_failure No changes since v1. -- 8< -- Use the recently added, internal functions, __argp_error_internal and __argp_failure_internal, to provide argp_error and argp_failure that can take long double arguments with IEEE binary128 format on platforms where long double can also take double format or some non-IEEE format (currently, this means powerpc64le). Tested for powerpc64le.
