View Thread: Tail. calls & Visual Studio lies

    Hi!
    I've been using tail. calls in my recent IL project and today I came across this post. If you go through it, you can see the performance differencies between call vs. tail. call instructions and the proof that the tail calls are barely optimized by .NET JITer. What a shame! Not only that the tail. calls are slow under .NET, but VS disassembly view lies you about the actual jitted code! Hope they'll improve the performance in .NET v4.0 (still dislike that v3.0 mess Expressionless)

    One may wonder what other things VS lies about...
