From 9f25935dda6973292e989302752d11e720e23c0c Mon Sep 17 00:00:00 2001 From: "Gabriel F. T. Gomes" Date: Thu, 11 Jul 2019 11:47:35 -0300 Subject: ldbl-128ibm-compat: Add error.h functions Use the recently added, internal functions, __error_at_line_internal and __error_internal, to provide error.h functions 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. Reviewed-by: Paul E.
