* Use a type to represent wasm table indices.
* Use a type to represent wasm global variable indices.
* Use a type to represent wasm memory indices.
* Use a type to represent wasm signature indices.
* Use PrimaryMap instead of Vec to protect against using wrong indices.
* Update to rustfmt-preview.
* Run "cargo fmt --all" with rustfmt 0.4.1.
rustfmt 0.4.1 is the latest release of rustfmt-preview available on the
stable channel.
* Fix a long line that rustfmt 0.4.1 can't handle.
* Remove unneeded commas left behind by rustfmt.
Previously, cretonne-wasm used its own Local struct for identifying
local variables. However, now that cretonne-frontend provides a
Variable struct, just use that instead.
This type is not longer used in any public interface, it has become an
internal implementation detail.
Also remove some unused exported types from the crate.
This allows the environment to control the signatures used for direct
function calls. The signature and calling convention may depend on
whether the function is imported or local.
Also add WasmRuntime::declare_func_{import,type} to notify the runtime
about imported and local functions. This is necessary so the runtime
knows what function indexes are referring to .
Since imported and local functions are now declared to the runtime, it
is no longer necessary to return hashes mapping between WebAssembly
indexes and Cretonne entities.
Also stop return null entries for the imported functions in the
TranslationResult. Just return a vector of local functions.
