Sergey Pepyakin 6253dd6fdf Args refactor (#71)
* Refactor TryInto → FromRuntimeValue.

Replace `TryInto<T, E>` with `FromRuntimeValue`.

The main difference is that `FromRuntimeValue` is implemented for the concrete type of the value we create, rather than on `RuntimeValue`. This makes more sense to me and seems more clear.

The `try_into` method is now implemented on `RuntimeValue` itself.

And finally, `FromRuntimeValue` has been made public.

* Impl AsRef<[RuntimeValue]> for RuntimeArgs

This impl can be used as an escape hatch if the user wants to use the inner slice.

* Little doc fixes for RuntimeArgs.

Fix br_table validation (#67)
Fixes #63

Fix is simple: all labels refered by the br_table instruction must have same value type (or NoResult in case if they don't have result). So we just take the default label and check other labels against it.

Bump parity-wasm version (#64) 2018-02-21 18:00:32 +03:00
Sergey Pepyakin 73c1451a84 Bump parity-wasm version to 0.25 (#62) 2018-02-19 19:32:38 +03:00
Sergey Pepyakin 9140e869e2 Update spec testsuite; Fix instantiation bug (#61)
The bug was about instantiating a module with elements segment being out-of-bounds, however, it was with zero length. E.g.:

```
(module
  (table 0 anyfunc)
  (elem (i32.const 1))
)
```

In our impl there was no out-of-bounds, because there was no attempt to set any table entry.

This change adds early check for specifically this case.

Move spec testsuite into tests. (#56)
Move all spec testsuite into `/tests` directory.

So it means that several changes will happen:

- Compilation will share common dependencies in target directory. This should make CI builds faster. This also should reduce space requirements.
- Common Cargo.lock file
- `cargo test` will include spec tests.
- `cargo check --tests` will also include spec tests.

Use wasmi ValueType for RuntimeValue instead pwasm (#52)
`RuntimeValue::default` takes `parity_wasm::elements::ValueType` as an input parameter. 

This change fixes it to be wasmi's `ValueType`.

Remove old fixtures. (#54)
Remove all old test fixtures that migrated in this repo from the parity-wasm.

Also, use .wast files instead of compiled .wasm. I believe this is more convenient than testing a .wasm file and having a corresponding .wast file, which might go out of sync.

Sergey Pepyakin e273b9e40a Just bump framestack limits. (#50)
These limits seems to be picked arbitrary, and I just made it arbitrary larger.

We need to reconsider these limits, ideally providing to user a way to customize the limits.

FWIW, When the last time I've tried to run gcc's torture testsuite with wasmi it also bumped into this limit.

Fixes #41.
