Nick Lewycky fa576093c2 Fix ExtraInfo on F32Add and similar.
We want to ignore the incoming pending NaN state (since the pending will propagate to the output if there was one on the input), and we want to add a new pending NaN state if we can (that is to say, if it isn't cancelled out by both inputs having arithmetic state). Do this by discarding the pending states on the inputs, intersecting them (to keep only the arithmetic state), then union in a pending nan state (which might do nothing, if it's arithmetic).

If the above sounds confusing, keep in mind that when a value is arithmetic, the act of performing the "NaN canonicalization" is a no-op. Thus, being arithmetic cancels out pending NaN states.

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
