Hi Evan
If a livein is not used in the block. It's live through.
thanks for doing this. Does this mean that the value in the livein
register is available in all blocks reachable from this one? If so,
why is propagateEHRegister needed? Or does it mean that the value
is available in successor

No. It just means the value is not clobbered

Is this necessary? ARM is already doing this by marking trivially re-
materializable instructions with let isReMaterializable = 1.
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
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?
