Description

Mozilla is publishing the PGO profiles for Linux at least (Windows is supposed to follow with Firefox 69 and macOS has no PGO) and the build as of Firefox 68 is still reproducible (including LTO): https://glandium.org/blog/?p=3923.

We should try this out for performance improvements.

That's really amazing! But what about MinGW?

Replying to cypherpunks:

There are no PGO profiles available for Windows which should be fixed soon. I guess we could then think about using PGO there as well.
