  "message": "internal/poly1305: Port sum_amd64.s to Avo\n\nThis implementation utilizes the same registers found in the reference\nimplementation, aiming to produce a minimal semantic diff between the\nAvo-generated output and the original hand-written assembly.\n\nTo verify the Avo implementation, the reference and Avo-generated\nassembly files are fed to `go tool asm`, capturing the debug output into\ncorresponding temp files. The debug output contains supplementary\nmetadata (line numbers, instruction offsets, and source file references)\nthat must be removed in order to obtain a semantic diff of the two\nfiles. This is accomplished via a small utility script written in awk.\n\nCommands used to verify Avo output:\n\nGOROOT\u003d$(go env GOROOT)\nASM_PATH\u003d\"internal/poly1305/sum_amd64.s\"\nREFERENCE\u003d\"b2d3a6a4b4d36521cd7f653879cf6981e7c5c340\"\n\ngo tool asm -o /dev/null -I \"$GOROOT\"/src/runtime -debug \\\n  \u003c(git cat-file -p \"$REFERENCE:$ASM_PATH\") \\\n  \u003e /tmp/reference.s\n\ngo tool asm -o /dev/null -I \"$GOROOT\"/src/runtime -debug \\\n  \"$ASM_PATH\" \\\n  \u003e /tmp/avo.s\n\nnormalize(){\n  awk \u0027{\n    $1\u003d$2\u003d$3\u003d\"\";\n    print substr($0,4)\n  }\u0027\n}\n\ndiff \u003c(normalize \u003c /tmp/reference.s) \u003c(normalize \u003c /tmp/avo.s)\n\nChange-Id: I80212c95d1b05335d7f6b73a3030b6f812f6105b\nReviewed-on: https://go-review.googlesource.com/c/crypto/+/600035\nReviewed-by: Roland Shoemaker \u003croland@golang.org\u003e\nReviewed-by: Filippo Valsorda \u003cfilippo@golang.org\u003e\nReviewed-by: Dmitri Shuralyov \u003cdmitshur@google.com\u003e\nLUCI-TryBot-Result: Go LUCI \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\n",
