Hmm... It looks like bug report is better.

> Copy that test to the AArch64 directory, change the triple to "aarch64-linux-gnu" and change the register patterns from r[0-9] to w[0-9].

I'd leave this move for separate commit from James, you or someone else from ARM.  It should be easier for you and this move is not related to my fix.

> Change the last (added) test in AArch64 to expect ldrh and see it pass.

If you move the test before I commit the patch I'll add new check there. If after you'll need to add it.

Thanks,
Evgeny
