Thanks Eli, I had no idea that OrderedBasicBlock existed! I'm now using this in a couple of places. I've also updated a couple of tests to highlight the register pressure changes. The scheduler does a good job, but it appears to struggle with some of the large blocks that we chuck at it and every cycle counts for these DSP kernels.
