Hmm, some issues caused by my reimplementation of #5534 (GVN + idempotency) for egraphs; switching this to draft for now.
cfallin commented on issue #5587:
Pushed updates, but I'll factor out the idempotent-GVN updates for egraphs into a separate PR tomorrow then rebase this.
cfallin commented on issue #5587:
Rebased on the idempotency fix; should be ready to review now!

I think one final location to touch doc-wise would be here too perhaps?

Label Messager: wasmtime:config
It looks like you are changing Wasmtime's configuration options. Make sure to
complete this check list:
[ ] If you added a new
Config
method, you wrote extensive documentation for
it.<details>
Our documentation should be of the following form:
```text
Short, simple summary sentence.More details. These details can be multiple paragraphs. There should be
information about not just the method, but its parameters and results as
well.Is this method fallible? If so, when can it return an error?
Can this method panic? If so, when does it panic?
Example
Optional example here.
```</details>
[ ] If you added a new
Config
method, or modified an existing one, you
ensured that this configuration is exercised by the fuzz targets.<details>
For example, if you expose a new strategy for allocating the next instance
slot inside the pooling allocator, you should ensure that at least one of our
fuzz targets exercises that new strategy.Often, all that is required of you is to ensure that there is a knob for this
configuration option in [wasmtime_fuzzing::Config
][fuzzing-config] (or one
of its nestedstruct
s).Rarely, this may require authoring a new fuzz target to specifically test this
configuration. See [our docs on fuzzing][fuzzing-docs] for more details.</details>
[ ] If you are enabling a configuration option by default, make sure that it
has been fuzzed for at least two weeks before turning it on by default.[fuzzing-config]: https://github.com/bytecodealliance/wasmtime/blob/ca0e8d0a1d8cefc0496dba2f77a670571d8fdcab/crates/fuzzing/src/generators.rs#L182-L194

cfallin commented on issue #5587:
In an extremely amusing twist, adding the deprecation warning for the
cranelift_use_egraphs
config option makes our fuzz target build throw a warning (because it can configure Cranelift not to use egraphs), and this makes our no-warnings build fail. I'm going to just remove the deprecation warning for now to get this in and am happy to talk about ways to warn while still using it internally in a followup PR.
