This implementation utilizes the same registers found in the reference implementation, aiming to produce a minimal semantic diff between the Avo-generated output and the original hand-written assembly. To verify the Avo implementation, the reference and Avo-generated assembly files are fed to `go tool asm`, capturing the debug output into corresponding temp files. The debug output contains supplementary metadata (line numbers, instruction offsets, and source file references) that must be removed in order to obtain a semantic diff of the two files. This is accomplished via a small utility script written in awk. Commands used to verify Avo output: GOROOT=$(go env GOROOT) ASM_PATH="argon2/blamka_amd64.s" REFERENCE="b2d3a6a4b4d36521cd7f653879cf6981e7c5c340" go tool asm -o /dev/null -I "$GOROOT"/src/runtime -debug \ <(git cat-file -p "$REFERENCE:$ASM_PATH") \ > /tmp/reference.s go tool asm -o /dev/null -I "$GOROOT"/src/runtime -debug \ "$ASM_PATH" \ > /tmp/avo.s normalize(){ awk '{ $1=$2=$3=""; print substr($0,4) }' } diff <(normalize < /tmp/reference.s) <(normalize < /tmp/avo.s) Change-Id: I3567eb80ef80dff248225f17470122c0a4e6951e Reviewed-on: https://go-review.googlesource.com/c/crypto/+/600315 Reviewed-by: Filippo Valsorda <filippo@golang.org> LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com> Reviewed-by: Dmitri Shuralyov <dmitshur@google.com> Reviewed-by: Roland Shoemaker <roland@golang.org> |
