* Don't run the spec_testsuite tests if the submodule isn't checked out.
This way, if someone checks out the repository without checking out the
submodules, they can still run "cargo test".
Also, fix a warning in the generated test runner code.
* Print a message if the spec_testsuite submodule is not enabled.
* Move the `#[cfg(test)]` to the top-level `mod`.
* Update the README.md.
Feature the wasmtime.dev website, update WASI content.
With Lightbeam moving into the Wasmtime repo, it's no longer necessary
to use git submodules to build Wasmtime.
RedundantReloadRemover participates in the state-recycling machinery
implemented in cranelift-codegen/src/context.rs, whose goal it is to cache
per-pass state so it can be used for compilation of multiple functions without
reallocation. Unfortunately RedundantReloadRemover::run simply ignores the
cached state and reallocates it new for each function. This patch fixes that.
This reduces the number of malloc'd blocks by about 2%.
* Put misc_testsuite behind a feature gate
This PR puts building and generating of misc_testsuite behind
a feature gate "misc_testsuite". This is mainly to allow projects
which pull `wasi-common` as a dependency not to have to have
`wasm32-wasi` target installed in order to build it as it currently
is.
* Update the CI
* Rename feature to wasm_tests
* Explain integration testing in the README
This commit fixes a bug where at the end of an `if..else..end`'s consequent
block, we would sometimes erroneously jump to the `else` block instead of to the
following destination block. Not good!
* clif-util: Make the `-t` flag work with the `wasm` subcommand
The presence of the flag was checked in the code, so it was essentially already
supported, but it was not properly configured when constructing
the CLI arguments parser.
* clif-util: also enable the `-c` flag for the `wasm` subcommand
Similar to the parent commit, this functionality is already supported, just a
mix up of the CLI parser construction made it not show up.
This commit introduces initial support for multi-value Wasm. Wasm blocks and
calls can now take and return an arbitrary number of values.
The encoding for multi-value blocks means that we need to keep the contents of
the "Types" section around when translating function bodies. To do this, we
introduce a `WasmTypesMap` type that maps the type indices to their parameters
and returns, construct it when parsing the "Types" section, and shepherd it
through a bunch of functions and methods when translating function bodies.
This adds a `--always-lightbeam` option as well as an `--always-cranelift`
option, to allow the compilation strategy to be selected via the
command-line. This also enables regular testing for Lightbeam.
