GN Migration status

[Shruthi Sreekanta]

We have been making lots of progress on all platforms for GN migration (what's that?) and here are some of the wins we are proud to share, to mention a few:

• Android is done!!! Woohooo!!! Thank you agrieve/jbudorick/pkotwicz for the awesome work!
• Builds of Chromium (the public code) now work on all 6 platforms
• Windows CQ bots are now on GN
  
• GN works on most simplechrome and some ebuild CrOS builds
  
• GN works on Mac on most targets
• All builders are using MB to control whether to use GYP or GN via src-side files, so flips can be tested via the tryservers
  
• As a nice side effect, the migration has triggered some cleanup tasks, for instance, complicated and incorrect delay-loading on Windows
  

Below is the current brief status/estimates:

Platform	Owner	Ship with GN	Ready for developers	All bots flipped/GYP turned off
Linux	dpranke	Done	Done	May end (almost done here!)
Android	agrieve jbudorick	Done	Done	Done
Windows	brucedawson	M53	Done
ChromeOS	stevenjb	M53	Done for linux-chromeos and simple chrome
Mac	rsesek	M53	Done
iOS	sdefresne	M53	End of May

Here are the open GN migration bugs. If you are interested in helping, please reach out to me. If you have other specific questions, please contact me or any of the folks on the cc list.

Thanks,

Shruthi
