commit de8aadd52c97f9a04d5e8709b16dc5baf9292a09
Author: Stefan Liebler <stli@linux.vnet.ibm.com>
Date: Mon Apr 13 21:16:56 2015 +0200
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.
