  "message": "cmd/compile,runtime: allocate defer records on the stack\n\nWhen a defer is executed at most once in a function body,\nwe can allocate the defer record for it on the stack instead\nof on the heap.\n\nThis should make defers like this (which are very common) faster.\n\nThis optimization applies to 363 out of the 370 static defer sites\nin the cmd/go binary.\n\nname     old time/op  new time/op  delta\nDefer-4  52.2ns ± 5%  36.2ns ± 3%  -30.70%  (p\u003d0.000 n\u003d10+10)\n\nFixes #6980\nUpdate #14939\n\nChange-Id: I697109dd7aeef9e97a9eeba2ef65ff53d3ee1004\nReviewed-on: https://go-review.googlesource.com/c/go/+/171758\nRun-TryBot: Keith Randall \u003ckhr@golang.org\u003e\nTryBot-Result: Gobot Gobot \u003cgobot@golang.org\u003e\nReviewed-by: Austin Clements \u003caustin@google.com\u003e\n",
