@YorikSar Based on the shown diff it doesn't look right 🤔

[YorikSar]

@infinisil diff between patches shows two places where conflicts happened: two in GCC package and one in meta itself. Conflicts in GCC boil down to the addition of mainProgram, and in meta - to lack of optimisation that landed separately in master and was not backported (I’ve replaced // with the new code here). If you inspect the new patch visually, it doesn’t have any additional pieces.

#409797 (comment) needs addressing first.
