alexcrichton opened PR #9741 from alexcrichton:pulley-default-target to bytecodealliance:main:

This commit updates the selection of the default target used by a Config to take into account the host architecture and possibly use Pulley instead of the host target itself. The goal here is that when a target isn't explicitly configured then Wasmtime is tasked with picking a reasonable default to execute code with. If neither Winch nor Cranelift has any support then the only way to possibly execute code would be with Pulley, so in these situations pulley becomes the default target.

The goal of this change is to make testing easier on 32-bit platforms where there is no compiler support. This means we won't have to update all tests to explicitly configure pulley on unsupported platforms. Additionally this means that an eventual wasmtime executable for 32-bit platforms will use Pulley by default and won't need any extra configuration.

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 nested structs).

  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.
