[PATCH] D58736: [System Model] Introduce a target system model

[David Greene via Phabricator via llvm-commits]

greened added a comment.

A larger design question I have about this is the proper place to put software prefetching configuration.  Right now it lives at the memory model level, in that a memory model specifies a cache heirachy along with a software prefetch configuration.  I wonder if we should allow for software prefetching configuration for each cache level, as targets might want different policies depending on which cache level they are prefetching into.  I don't think we have any examples of that in the codebase today but I can imagine cases where targets might want it.
