From b5187fa61b34ff94513fcf8f64ff5c588c211d06 Mon Sep 17 00:00:00 2001 From: Jesse Zhang Date: Wed, 17 Jul 2013 16:40:46 +0800 Subject: tremor: add a patch to build with arm thumb Add IT instructions so that it builds with thumb tunes. ARM mode won't be affected since IT is a pseudo-instruction in ARM mode.
