Raw Blame History

From: "Rodrigo R. Galvao" <rosattig@br.ibm.com>
Date: Wed, 11 Oct 2017 08:41:47 +0000
Subject: New patch proposal for PPC64 support
Create a patch for PPC64 support based on
https://github.com/LuaJIT/LuaJIT/pull/140.
It replaces the old patch since this new one is more likely to be merged
with luajit upstream.
Author: Rodrigo R. Galvao <rosattig@br.ibm.com>
