Sean Stangl (Dec 18 2019 at 21:24): Sean Stangl (Dec 18 2019 at 21:24):@Benjamin Bouvier Are we ready to remove the basic-blocks feature gate and make it default?
fitzgen (he/him) (Dec 18 2019 at 21:26):is the plan to completely remove EBBs, or make them available-but-not-on-by-default? or first disable, but eventually remove?
Sean Stangl (Dec 18 2019 at 21:27):The plan is to remove them in the near-term. I'd still like to keep them as an optimization for one particular pass (I believe wasm IR to CLIF conversion) as an internal detail.
Sean Stangl (Dec 18 2019 at 21:28):The new regallocs that @Benjamin Bouvier and Julian Seward (who's not here!) are writing likely depend on non-ebb representations.

https://github.com/bytecodealliance/cranelift/commit/decec8bb4e29572c13e6e325c2c2ebb1a6ea7b4f <-- basic-blocks has been default for a few months now, fwiw. as soon as EBBs are removed i plan on closing https://github.com/bytecodealliance/cranelift/issues/1219.
Benjamin Bouvier (Dec 19 2019 at 08:16):Yes, the plan is to remove basic blocks entirely. If we wanted to keep them, we'd need either to maintain all the optimization passes so they work with EBBs, or disable them all. So I'm strongly in favor of removing them entirely.
Benjamin Bouvier (Dec 19 2019 at 08:17):For the bikeshedding matters, I think "Block" / "block" is better than "Bb" / "bb" as a replacement for "Ebb" / "ebb". We've had "Value" in the past, same number of letters, and fully-expanded is less ambiguous and more readable than the acronym.
