Go's compiler now counts IR nodes to order functions more intelligently, while the benchmark harness stumbles on recent upgrades.

The compiler team landed a change that replaces statement-count heuristics with actual IR node counting during function compilation ordering [1]. This moves the needle on compile performance for large functions, though final numbers are still being benchmarked. Meanwhile, the benchmark suite hit friction after upgrading build targets: the Istio benchmark harness now invokes go build without an explicit output path, breaking when working directories shifted [2]. A follow-up fix is incoming to handle the Kubernetes builds that failed under the new go-build setup [3]. On the testing side, Alan Donovan landed a quick fix for a misspelled analyzer name in cmd/vet tests [4], keeping the vet suite clean heading into the next release cycle.
