From 6523585c66c04cea54df50013df8886b589847d8 Mon Sep 17 00:00:00 2001 From: David Walter Seikel Date: Mon, 23 Jan 2012 23:36:30 +1000 Subject: Add luaproc and LuaJIT libraries. Two versions of LuaJIT, the stable release, and the dev version. Try the dev version first, until ih fails badly. --- libraries/luajit-2.0/src/lj_target_ppc.h | 279 +++++++++++++++++++++++++++++++ 1 file changed, 279 insertions(+) create mode 100644 libraries/luajit-2.0/src/lj_target_ppc.h (limited to 'libraries/luajit-2.0/src/lj_target_ppc.h') diff --git a/libraries/luajit-2.0/src/lj_target_ppc.h b/libraries/luajit-2.0/src/lj_target_ppc.h new file mode 100644 index 0000000..d8fbea6 --- /dev/null +++ b/libraries/luajit-2.0/src/lj_target_ppc.h @@ -0,0 +1,279 @@ +/* +** Definitions for PPC CPUs. +** Copyright (C) 2005-2011 Mike Pall.
