I'm in the process of implementing a very nice an "obvious" simplification: using the same number and arrangement/mapping of virtual registers to spill slots across all fragment partitions in a trace. This opens up the obvious question/hope/idea: now that the structure of spill slots is identical across fragment partitions: can we merge all the spilling/filling across partitions, where there once was no such merging? This would be a super nice things to have :-D
