[llvm-dev] Why the binary size in trunk are smaller significantly?

[chuanqi.xcq via llvm-dev]

Hi all,

I am working on how to reduce the size of the binary produced for coroutine with `-g`.

In a private code bases, I find that the binary size produced in llvm-11 is 60M while the size produced in trunk is 51M.

I tried to find the patch who made this change in git log or in phabricator by keywords like `reduce`, 'size' or 'binary'. But I find nothing.

May I ask does anyone knows what patch makes the binary size smaller from llvm-11 to now?

thanks,
Chuanqi
