  "message": "cmd/compile: introduce LivenessMap and LivenessIndex\n\nCurrently liveness only produces a stack map index at each safe point,\nso the information is summarized in a map[*ssa.Value]int. We\u0027re about\nto have both a stack map index and a register map index, so replace\nthe int with a LivenessIndex type we can extend, and replace the map\nwith a LivenessMap that we can also change more easily in the future.\n\nThis also gives us an easy hook for defining the value that means \"not\na safe point\".\n\nPasses toolstash -cmp.\n\nFor #24543.\n\nChange-Id: Ic4c069839635efed4fd0f603899b80f8be3b56ec\nReviewed-on: https://go-review.googlesource.com/109347\nRun-TryBot: Austin Clements \u003caustin@google.com\u003e\nTryBot-Result: Gobot Gobot \u003cgobot@golang.org\u003e\nReviewed-by: Keith Randall \u003ckhr@golang.org\u003e\n",
