+The code for the benchmark can be found [here](https://gist.github.com/binji/b8e8bc0c0121235d9f1668bc447c7f8c).
+Note that this will not run properly without a WebAssembly implementation of `move_memory`. For my tests, I
+hacked a version of v8 to replace any exported function called `memcpy` or `memmove` with a new function with
+the following contents:
+
+```wasm
+(func (param $dst i32) (param $src i32) (param $size i32) (result i32)
+  get_local $dst
+  get_local $src
+  get_local $size
+  move_memory
+  get_local $dst)
+```
