SIMD · Issue #41 · WebAssembly/design (original) (raw)

We current suggest that we'll support SIMD.js (RFC).

The C++ standard committee is currently discuss adding explicit SIMD support as well as auto-vectorization hints to the language, and vector execution policies to executors. C++ isn't the only language that we want wasm to support, but we should make sure that what we implement can support C++! There may need to be some reconciliation between SIMD.js and C++ for the sake of wasm and not JavaScript.

Here are the recent relevant papers (older ones may also be relevant):

• SIMD Polymorphism
• Changes to vector_execution_policy
• SIMD Types: The Mask Type & Write-Masking
• SIMD Types: The Vector Type & Operations
• Language Extensions for Vector loop level parallelism
• An Abstract Model of Vector Parallelism
• SIMD Types: ABI Considerations
