Hi,
As of 04-07-2014, the latest version of crypto/sha/asm/sha512-x86_64.pl
(commit 29be3f6411) in the master branch shows the following at line 2309:
$code.=<<___ if ($SZ==4 && $shext);
Seeing that the variable $shext doesn't exist, but $shaext does, this
might be a typo.
Please find a (micro)patch attached to change this line to the following:
$code.=<<___ if ($SZ==4 && $shaext);
Cheers,
Peter Mosmans
