Function from64

src/parseTools.mjs:1027–1030

(x)

// Convert a pointer value under wasm64 from BigInt (used at local level API
// level) to Number (used in JS library code).  No-op under wasm32.
function from64(x) {
  if (!MEMORY64) return '';
  return `${x} = Number(${x});`;
}

// Like from64 above but generate an expression instead of an assignment
// statement.
