[LLVMdev] SchedMachineModel clarifications

[Mike Vermeulen]

If you haven't found it yet, the last public AMD Software Optimization
Guide for Family 15h is here:
http://developer.amd.com/wordpress/media/2012/03/47414_15h_sw_opt_guide.pdf

This one describes both Bulldozer and Piledriver processors.  Chapter 2
will given an overview of the Microarchitecture and Appendix B gives some
additional details on which pipes are used for where.

I haven't yet looked in detail at your patch to check your model, but at
minimum the comments, references and naming still all refer to Sandy Bridge
which is confusing at best - and leaves it a bit unclear what you've
intentionally changed and what is there because it was cloned from the
Sandy Bridge model but yet changed.

Do you have any performance measurements?
