Hi,  
Is there a way to save the output of `@code_native` to a txt file?  
My ouput is very long and I can’t copy it manually to a file because it is more than the terminal buffer.  
Thank you

I’m not sure if there’s a way to do this via the macro syntax, but you can use the function syntax to specify the `io` destination:

```julia
help?> code_native
search: code_native @code_native

  code_native([io=stdout,], f, types; syntax=:att, debuginfo=:default, binary=false, dump_module=true)

  Prints the native assembly instructions generated for running the method matching
  the given generic function and type signature to io.

```

The translation of `@code_native f(a,b)` is roughly `code_native(stdout, f, typeof((a,b)))`. Replace `stdout` with a file handle (created via `open`) to dump to a file, for example.
