[RFC] Being explicit in the cost model
Hi,
I have been working in the TargetTransformInfo layer for the last few weeks with several ongoing goals:

> Help empower the backends.
> Reduce the surface area of the API.

How shall I evaluate the latency of each instruction in LLVM IR?

similar job for LLVM IR?
Thanks!
