Try it

(module
  (import "console" "log" (func $log (param i32)))
  (func $main
    v128.const f32x4 0 0 0 1.2
    v128.any_true

    call $log ;; log the result
  )
  (start $main)
)

WebAssembly.instantiateStreaming(fetch("{%wasm-url%}"), { console });

v128.any_true

The v128.any_true instruction.

Type

[input] -> [output]

input

The input v128 value interpretation. This can be an integer type (for example, i16x8) or floating point type (for example, f32x4).

output

The output value. This is an i32 type equal to 1 if the v128 input contains any non-zero bits, or 0 if all bits are 0.
