From 3e121542d8b7ab5201c47bbd3ba5611a23c54759 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Parm=C3=A9nides=20GV?= Date: Wed, 11 Jun 2014 11:56:59 +0200 Subject: Correctly connects to millipede. Location keyword on android.cfg isn't supported, EIP corresponding code has been commented out. I think we should support it in ics-openvpn, so that we can show the location instead of the server name. I've updated all opensssl, openvpn, etc. subprojects from rev 813 of ics-openvpn, and jni too. --- app/openssl/crypto/sha/asm/sha512-s390x.pl | 63 ++++++++++++++++++++---------- 1 file changed, 42 insertions(+), 21 deletions(-) (limited to 'app/openssl/crypto/sha/asm/sha512-s390x.pl') diff --git a/app/openssl/crypto/sha/asm/sha512-s390x.pl b/app/openssl/crypto/sha/asm/sha512-s390x.pl index e7ef2d5a..079a3fc7 100644 --- a/app/openssl/crypto/sha/asm/sha512-s390x.pl +++ b/app/openssl/crypto/sha/asm/sha512-s390x.pl @@ -26,6 +26,26 @@ # favour dual-issue z10 pipeline.
