[llvm-dev] Porting improvements from llvm-bolt to LLVM

[Alexander Zaitsev via llvm-dev]

Hello.

I think you heard about Facebook's llvm-bolt binary optimizer 
(https://github.com/facebookincubator/BOLT 
https://code.fb.com/data-infrastructure/accelerate-large-scale-applications-with-bolt/).

This utility is based on LLVM. And I think it's possible to integrate 
some features from BOLT to llvm upstream. Probably PGO implementation 
can get some improvements, but I am not LLVM-developer, so I am not sure.

What do you think about the idea? Is it possible? Or bolt features are 
useless for LLVM?


Best regards

Alexander Zaitsev
