Hi Jiangning,

Sorry I didn't get a chance to reply on Friday, and thanks for
reworking the patch.

Fair enough.

I think it looks pretty much OK now, though I'd be happier if there
was a test that we *weren't* generating fmla instructions all the time
(perhaps with a comment about it being intentional). It's a very
tempting "optimisation" to make.

I think you should commit, with or without that though. I'll take a
look over the revision after-wards.
