In a world where the register allocator can aggressively remat misc. loads, will it still be interesting to identify spill reloads? You mentioned at one point that you have some scripts which know how to read some of these comments. Would it be possible for you to include these scripts with the...

The idea is to get a sense of how well regalloc is doing. And you can't remat everything. &g...
