To compile code to WebAssembly with SIMD instructions, just use the generic+simd128 CPU target:

    zig cc  -Ofast --target=wasm32-wasi -mcpu=generic+simd128 example.c
    zig c++ -Ofast --target=wasm32-wasi -mcpu=generic+simd128 example.cpp

Or with a build file:

    zig build -Drelease-fast -Dtarget=wasm32-wasi -Dcpu=generic+simd128
