Instead of ensuring outputs are arithmetic NaNs on every function, we tag them as pending such a check, so that a sequence of computation can have a single canonicalization step at the end. There's an extra wriggle for SIMD. The Wasm type system only indicates them as V128, so it's possible that we might do computations as F32x4Add, I8x16Add, F64x2Add in a row with no other computations in between. Thus, most SIMD functions apply pending canonicalizations to their inputs, even integer SIMD operations.
Wasmer LLVM backend
Wasmer is a standalone JIT WebAssembly runtime, aiming to be fully compatible with Emscripten, Rust and Go. Learn more.
This crate represents the LLVM backend integration for Wasmer.
Usage
Usage in Wasmer Standalone
If you are using the wasmer CLI, you can specify the backend with:
wasmer run program.wasm --backend=llvm
Usage in Wasmer Embedded
If you are using Wasmer Embedded, you can specify
the LLVM backend to the compile_with function:
use wasmer_llvm_backend::LLVMCompiler;
// ...
let module = wasmer_runtime_core::compile_with(&wasm_binary[..], &LLVMCompiler::new());
