    [wasm/tools] Add import profiler · 4eb53245
    Ben L. Titzer authored
    Add a profiler for functions imported to WASM instances. This profiler
    is implemented entirely in JavaScript and monkey-patches
    WebAssembly.instantiate() and new WebAssembly.Instance() to instrument
    the imported functions to each instance in order to count their
    invocations and cumulative time.
