I don't have measurements to corroborate this, but here's a mailing list thread where folks are talking about it (split across two URLs, the OP posted in April and then there was a followup in May): http://lists.llvm.org/pipermail/llvm-dev/2020-April/140938.html https://lists.llvm.org/pipermail/llvm-dev/2020-May/141482.html So there definitely seems to be *something* going on, and you are indeed not crazy. :)
