Volodymyr Sapsai 83f4c3af02 [modules] Do not cache invalid state for modules that we attempted to load. ... Partially reverts 0a2be46cfd as it turned out to cause redundant module rebuilds in multi-process incremental builds. When a module was getting out of date, all compilation processes started at the same time were marking it as `ToBuild`. So each process was building the same module instead of checking if it was built by someone else and using that result. In addition to the work duplication, contention on the same .pcm file wasn't making builds faster. Note that for a single-process build this change would cause redundant module reads and validations. But reading a module is faster than building it and multi-process builds are more common than single-process. So I'm willing to make such a trade-off. rdar://problem/54395127 Reviewed By: dexonsmith Differential Revision: https://reviews.llvm.org/D72860		2020-01-16 17:12:41 -08:00
