From de8aadd52c97f9a04d5e8709b16dc5baf9292a09 Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Mon, 13 Apr 2015 21:16:56 +0200 Subject: Set errno for log1p on pole/domain error. According to bug 6792, errno is not set to ERANGE/EDOM by calling log1p/log1pf/log1pl with x = -1 or x < -1. This patch adds a wrapper which sets errno in those cases and returns the value of the existing __log1p function. The log1p is now an alias to the wrapper function instead of __log1p. The files in sysdeps are reflecting these changes. The ia64 implementation sets errno by itself, thus the wrapper-file is empty. The libm-test is adjusted for log1p-tests to check errno.
