big.LITTLE will return 0 on getCacheLineSize(). See

Basically, with write-though, every store is a non-temporal store (Or
temporal stores being a write-through, depending on how to view it)

RFC: System (cache, etc.) model for LLVM
Hi,
thank you for sharing the system hierarchy model. IMHO it makes a lot
of sense, although I don't know which of today's passes would make use
of it. Here are my remarks.
I am wondering how one could model the following features using this
model, or whether they should be part of a performance model at all:
* ARM's big.LITTLE
* NUMA hierarchies (are the NUMA domains
