How to understand @VIL in dalvik bycode

Question

I use ida open classes.dex, and it show

CODE:00189570                 invoke-virtual                  {v0, v1, menu}, <void MenuInflater.inflate(int, ref) imp. @ _def_MenuInflater_inflate@VIL>

I don't understand the @VIL in the end of line, what's it? the full code

//MainActivity.java
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

the full ida view

public boolean ro.rotry.MainActivity.onCreateOptionsMenu(
CODE:00189564       android.view.Menu menu)
CODE:00189564 this = v2
CODE:00189564 menu = v3
