From 27594eeae6f40a402bc3110f06d57975168e74e3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Parm=C3=A9nides=20GV?= Date: Thu, 4 Jun 2015 19:20:15 +0200 Subject: ics-openvpn as a submodule! beautiful ics-openvpn is now officially on GitHub, and they track openssl and openvpn as submodules, so it's easier to update everything. Just a git submodule update --recursive. I've also set up soft links to native modules from ics-openvpn in app, so that we don't copy files in Gradle (which was causing problems with the submodules .git* files, not being copied). That makes the repo cleaner. --- app/openssl/crypto/sha/asm/sha1-mips.pl | 354 -------------------------------- 1 file changed, 354 deletions(-) delete mode 100644 app/openssl/crypto/sha/asm/sha1-mips.pl (limited to 'app/openssl/crypto/sha/asm/sha1-mips.pl') diff --git a/app/openssl/crypto/sha/asm/sha1-mips.pl b/app/openssl/crypto/sha/asm/sha1-mips.pl deleted file mode 100644 index f1a702f3..00000000 --- a/app/openssl/crypto/sha/asm/sha1-mips.pl +++ /dev/null @@ -1,354 +0,0 @@ -#!/usr/bin/env perl - -# ==================================================================== -# Written by Andy Polyakov for the OpenSSL -# project.
