<pre>git bisect points to this patch which miscompiles libjpeg in Android compiled
for aarch64:
<a href="http://reviews.llvm.org/rL273755">http://reviews.llvm.org/rL273755</a>
Basic instructions on how to reproduce the problem are in
<a href="https://github.com/android-ndk/ndk/issues/110">https://github.com/android-ndk/ndk/issues/110</a>
I first thought that a change to GVN PRE was producing the wrong code, though
git bisect now points to this patch: most likely PRE exposes a pattern that is
then producing wrong code with the change to the scheduler.
I am still struggling reducing a testcase with bugpoint.</pre>
