...us, that would be wonderful :)
The analysis currently computes, internally, for a given BB:
EarliestLoadHoistBarrier (used to see if you can move something out of a
block)
LatestLoadHoistBarrier (used to find the latest safe insertion point in a
block, if any)
EarliestStoreSinkBarrier (insertion)
LatestStoreSinkBarrier (movement)
(stores are maythrow dependent, loads are
isGuaranteedToTransferExecutionToSuccessor dependent)
I'm still coming up with the external API, the users all want to know
either:
1. Can i move a load up out of this block to a direct predecessor
2. Can i move a store down out of this...
