profiles/base: [QA] mask USE=pch |
| 9 |
|
| 10 |
PCH is notoriously fragile & unstable. It often leads |
| 11 |
to (unclear) build failures and has questionable |
| 12 |
value in terms of performance, at least for the general |
| 13 |
case. |
| 14 |
|
| 15 |
Users are free to unmask it if they wish at their |
| 16 |
own risk. |
