  "message": "Add statistics to Util/Transforms/FoldGlobals.cpp. (#7535)\n\nFollowing up on https://github.com/google/iree/pull/7312#discussion_r728261108, this adds more [statistics](https://mlir.llvm.org/docs/PassManagement/#pass-statistics) to IREE\u0027s compiler passes. I personally build with the CMake option `-DLLVM_FORCE_ENABLE_STATS\u003dON` so the `-pass-statistics` flag works in `RelWithDebInfo` builds, but we don\u0027t yet have anything like that configured on our CI or recommended in our developer documentation. See also https://github.com/google/iree/issues/6161#issuecomment-912635307 for how this could be useful.\r\n\r\nSample output on [bert_encoder_unrolled_fake_weights.mlir](https://github.com/google/iree/blob/main/iree/test/e2e/models/bert_encoder_unrolled_fake_weights.mlir) (fake weights are folded aggressively 😛):\r\n\r\n```\r\nmlir::iree_compiler::IREE::Util::`anonymous-namespace\u0027::FoldGlobalsPass\r\n  (S) 1113 global ops before folding - Number of util.global ops before folding\r\n  (S)    7 global ops after folding  - Number of util.global ops after folding\r\n```",
