Description Saam Barati 2021-12-21 18:31:23 PST
Probably will be a perf win for first run programs.
Comment 1 Saam Barati 2021-12-21 18:31:43 PST
If we add a new lightweight Baseline JIT, this probably isn't necessary.

Fixed latent regalloc bug in O0. I think this patch is mostly ready. But I'm going to implement exceptions in Air first, since that'll make some of the tier up logic nicer, and it's a nice to have anyways, since we want all tiers supporting all wasm features.
