  "message": "cmd/compile: make loop finder more aware of irreducible loops\n\nThe loop finder doesn\u0027t return good information if it\nencounters an irreducible loop.  Make a start on improving\nthis, and set a function-level flag to indicate when there\nis such a loop (and the returned information might be flaky).\n\nUse that flag to prevent the loop rotater from getting\nconfused; the existing code seems to depend on artifacts\nof the previous loop-finding algorithm. (There is one\nirreducible loop in the go library, in \"inflate.go\").\n\nChange-Id: If6e26feab38d9b009d2252d556e1470c803bde40\nReviewed-on: https://go-review.googlesource.com/42150\nRun-TryBot: David Chase \u003cdrchase@google.com\u003e\nTryBot-Result: Gobot Gobot \u003cgobot@golang.org\u003e\nReviewed-by: Cherry Zhang \u003ccherryyz@google.com\u003e\n",
