<pre>There has been a lot of activity on improving scheduler models recently, but
the documentation on explaining how to write a model and how it is used
(instruction scheduling, llvm-mca, etc.) is very poor.
<a href="http://llvm.org/docs/WritingAnLLVMBackend.html#instruction-scheduling">http://llvm.org/docs/WritingAnLLVMBackend.html#instruction-scheduling</a>
We could at least begin by writing up Javed/Florian's "Writing Great Machine
Schedulers" tutorial from the 2017 US DevMtg (llvm.org/devmtg/2017-10/).</pre>
