Sorry, I meant for general automation. Our final spins (especially LTO/PGO builds) should remain whatever gives us maximum perf. (not making any claims myself here!) Our PGO/LTO builds can take 10x+ what our normal integration builds take if it nets us a few percentage points of runtime perf. I suppose it becomes a question of divergence between fast-building builds and 'final' PGO/fully-optimized builds. We already have this to some extent with PGO vs non-PGO builds. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
