This adds support for `.wat` tests in `cranelift-filetest`. The test runner translates the WAT to Wasm and then uses `cranelift-wasm` to translate the Wasm to CLIF. These tests are always precise output tests. The test expectations can be updated by running tests with the `CRANELIFT_TEST_BLESS=1` environment variable set, similar to our compile precise output tests. The test's expected output is contained in the last comment in the test file. The tests allow for configuring the kinds of heaps used to implement Wasm linear memory via TOML in a `;;!` comment at the start of the test. To get ISA and Cranelift flags parsing available in the filetests crate, I had to move the `parse_sets_and_triple` helper from the `cranelift-tools` binary crate to the `cranelift-reader` crate, where I think it logically fits. Additionally, I had to make some more bits of `cranelift-wasm`'s dummy environment `pub` so that I could properly wrap and compose it with the environment used for the `.wat` tests. I don't think this is a big deal, but if we eventually want to clean this stuff up, we can probably remove the dummy environments completely, remove `translate_module`, and fold them into these new test environments and test runner (since Wasmtime isn't using those things anyways).

//! Performs translation from a wasm module in binary format to the in-memory form
|
|
//! of Cranelift IR. More particularly, it translates the code of all the functions bodies and
|
|
//! interacts with an environment implementing the
|
|
//! [`ModuleEnvironment`](trait.ModuleEnvironment.html)
|
|
//! trait to deal with tables, globals and linear memory.
|
|
//!
|
|
//! The crate provides a `DummyEnvironment` struct that will allow to translate the code of the
|
|
//! functions but will fail at execution.
|
|
//!
|
|
//! The main function of this module is [`translate_module`](fn.translate_module.html).
