Yes, it looks good. I can deal with LDRcp and friends later.
Thanks.

What do you think about the attached patch? It's not tested yet, but it
shows what I
We can eliminate LDRcp, that's fine.
However, I still don't like the separate hook and targetinstrinfo
bit. Dan, can you have just a single isTriviallyReMaterializable hook
that encompass all these?

It's not necessary, but it seems cleaner :-).
In the ARM target, other than instructions that are always trivially
rematerialiable, there's only LDR, with a ReMat
Hi Dan,
Is this necessary? ARM is already doing this by marking trivially re-
materializable instructions with let isReMaterializable = 1.
