This somewhat cuts down on duplicate dependencies. `wast` is used in a much older version (`11.0.0`) by `witx`, and can be updated without issues there as well, but this at least gets us from 3 copies to 2.
* Wasmtime 0.15.0 and Cranelift 0.62.0. (#1398)
* Bump more ad-hoc versions.
* Add build.rs to wasi-common's Cargo.toml.
* Update the env var name in more places.
* Remove a redundant echo.
The `faerie` crate does this by default. `object` itself does not, but
it seems reasonable to make this change for parity between
`cranelift-faerie` and `cranelift-object`.
Experience with the `define_function` API has shown that returning
borrowed slices of `TrapSite` is not ideal: the returned slice
represents a borrow on the entire `Module`, which makes calling back
into methods taking `&mut self` a bit tricky.
To eliminate the problem, let's require the callers of `define_function`
to provide `TrapSink` instances. This style of API enables them to
control when and how traps are collected, and makes the `object` and
`faerie` backends simpler/more efficient by not having to worry about
trap collection.
This patch updates or removes all references to the Cranelift repository. It affects links in README documents, issues that were transferred to the Wasmtime repository, CI badges, and a small bunch of sundry items.
Update the documentation for the merger, and also for various changes in
Cranelift. Remove some old obsolete documentation, and convert the remaining
Sphinx files to Markdown. Some of the remaining content is still out of
date, but this is a step forward.
The current interface of `cranelift-module` requires consumers who want
to be informed about traps to discover that information through
`Module::Product`, which is backend-specific. Since it's advantageous
to manipulate this information in a backend-agnostic way, this patch
changes `Module::define_function{,_bytes}` to return information about
the traps contained in the function being defined.
This is useful for me because I name the module after the file, which
comes from the filesystem and may not be valid UTF8.
This change is backwards-compatible.
* move trap site definitions into cranelift-module
`cranelift-faerie` and `cranelift-object` already have identical
definitions of structures to represent trap sites. We might as well
merge them ahead of work to define functions via a raw slice of bytes
with associated traps, which will need some kind of common structure for
representing traps anyway.
* cranelift-module: add `define_function_bytes` interface
This interface is useful when the client needs to precisely specify the
ordering of bytes in a particular function.
* add comment about saving files for `perf`
* use new zeroinit API for faerie
* use bss for cranelift-object
* don't crash when initializing bss
* fix formatting
* Improve code locality

* use `as` instead of try_into() for usize -> u64
* don't allocate unnecessarily in `faerie`

This removes the need to call `finalize_definitions` for cranelift-object.
`finalize_definitions` is only intended for backends that produce
finalized functions and data objects, which cranelift-object does not.
