Nick Fitzgerald d5d3e46334 cli-support: Skip generating JS shims for imports when unnecessary ... After this change, any import that only takes and returns ABI-safe numbers (signed integers less than 64 bits and unrestricted floating point numbers) will be a direct import, and will not have a little JS shim in the middle. We don't have a great mechanism for testing the generated bindings' contents -- as opposed to its behavior -- but I manually verified that everything here does the Right Thing and doesn't have a JS shim: ```rust \#[wasm_bindgen] extern "C" { fn trivial(); fn incoming_i32() -> i32; fn incoming_f32() -> f32; fn incoming_f64() -> f64; fn outgoing_i32(x: i32); fn outgoing_f32(y: f32); fn outgoing_f64(z: f64); fn many(x: i32, y: f32, z: f64) -> i32; } ``` Furthermore, I verified that when our support for emitting native `anyref` is enabled, then we do not have a JS shim for the following import, but if it is disabled, then we do have a JS shim: ```rust \#[wasm_bindgen] extern "C" { fn works_when_anyref_support_is_enabled(v: JsValue) -> JsValue; } ``` Fixes #1636.		2019-07-11 15:44:16 -07:00
