The effect of Meltdown and Spectre in our communities

> While not explicitly designed for that, there have been good results with the RISC-V ISA: https://carrv.github.io/2017/papers/clark-rv8-carrv2017.pdf

That looks like RV8 on x86. I was more thinking of the other way round. Some ISA which gave the recompiler some control over execution units, to replicate some of the out-of-order things which are normally done internally using software and basic hardware, and possibly more control over the various caches. For intellectual interest, does anyone else have thoughts about what would be possible or necessary, and whether any interesting level of performance would be achievable?
