But your contention is that fixing this will reduce build times, right? Did you observe a change in build times with dzbarsky's patch, or any of the other work that you have done? Or is the improvement in build times completely speculative at this point? I agree with Benjamin that our efforts may be better targeted at PCH, if headers are really a bottleneck. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
