These is one test failure remaining with V128 global variables. * Fix trunc_sat. We need both the largest float that can be converted to an int and the largest int, they are not the same number. * Implement calling of functions that take V128 by passing in two i64's. * Improve support for V128 in spectests. Parse binary modules with the same features as the outer spectest. Fix compilation error involving Result in emitted .rs file. Handle V128 in more cases when producing .rs file. Parse the wast script with SIMD enabled. * Adjust the WAVM spectest so that it parses with WABT and mostly passes with wasmer. Wabt is particular about ints not having decimal places and floats having decimal places. Wasmer does not support mutable globals or shared memory. Tests of shuffles are disabled. Some assert_invalid tests that wabt won't even parse are disabled. |

Wasmer Libraries
Wasmer is modularized into different libraries, separated into three main sections:
Runtime
The core of Wasmer is the runtime, which provides the necessary abstractions to create a good user experience when embedding.
The runtime is divided into two main libraries:
- runtime-core: The main implementation of the runtime.
- runtime: Easy-to-use API on top of
runtime-core.
Integrations
The integration builds on the Wasmer runtime and allow us to run WebAssembly files compiled for different environments.
Wasmer intends to support different integrations:
- WASI: run WebAssembly files with the WASI ABI.
- Emscripten: run Emscripten-generated WebAssembly files, such as Lua or nginx.
- Go ABI: we will work on this soon! Want to give us a hand? ✋
- Blazor: research period, see tracking issue
Backends
The Wasmer runtime is designed to support multiple compiler backends, allowing the user to tune the codegen properties (compile speed, performance, etc) to best fit their use case.
Currently, we support multiple backends for compiling WebAssembly to machine code:
- singlepass-backend: Single pass backend - super fast compilation, slower runtime speed
- clif-backend: Cranelift backend - slower compilation, normal runtime speed
- llvm-backend: LLVM backend - slow compilation, native runtime speed
