dimitris-aspetakis opened PR #9150 from karouzakisp:main
to bytecodealliance:main
:
The option
--emit-opt-clif
follows the--emit-clif
implementation from wasmtime's CLI, but the output comes with the egraph optimizations applied. It has been helpful for work on #6260. From discussions in zulip, it seemed more generally desirable.
- I consider some small changes in
crates/cranelift/src/compiler.rs
to be a bit "hacky", probably due to my inexperience with the borrow checker...- The current state does not include support for the wasmtime explorer.

--emit-clif
and--emit-opt-clif
are the same) — I haven't created any since I'm not even sure about the CLI interface you would prefer.- The current state does not include support for the wasmtime explorer.

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

Thanks for this! As a possible alternative though, what do you think about not adding a new option but redefining
--emit-clif
as this option instead? That way optimized clif would be emitted by deafult and non-optimized clif could be emitted with-C opt-level=0
