# Requirements:
#   clang - The classes/structs you want to dump must be used in code at least once, not just defined.
#   MSVC  - The classes/structs you want to dump must have "MEOW" in the name for "reportSingleClass" to work.
# Usage:
#   $ make dump_vtables file=test.cpp
dump_vtables:
  clang -cc1 -fdump-record-layouts -emit-llvm  $(file) > clang-vtable-layout-$(file).txt
  clang -cc1 -fdump-vtable-layouts -emit-llvm  $(file) > clang-record-layout-$(file).txt
  g++ -fdump-lang-class=$(file).txt $(file)
  cl.exe $(file) /d1reportSingleClassLayoutMEOW > msvc-single-class-vtable-layout-$(file).txt

/**
* 使用方法：
* 1. 用 Chrome 打开歌单的 web 页面（可以通过分享拿到链接，链接类似这样：http://music.163.com/playlist?id=xxx&userid=yyy）
* 2. 然后右键“检查”（如果有左上角有 device 选项，需要选择 Laptop 开头的，可以在 Edit/编辑 里添加）
* 3. 在 console 里输入下面脚本，即可输出 “歌曲名 - 歌手名” 格式的内容：

    Springsteen - Eric Church
    Chattahoochee - Alan Jackson
    Baby Now That I Found You - Alison Krauss
    Check Yes or No - George Strait

Enable bbr on Ubuntu 16.04

1. Make sure kernel version is 4.9 or newer:

   uname -r

   Install Hardware Enablement Stack (HWE) to update kernel automaticly:

# The trick is to link the DeviceSupport folder from the beta to the stable version.
# sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)

# Support iOS 15 devices (Xcode 13.0) with Xcode 12.5:
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

# Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions

# (A similar approach works for older versions too, just change the version number after DeviceSupport)
