If you want to test, you'll need the dev branch of the code, do a cmake in the test/bench folder, then run ./bench-gf16 -fmuladdmp

This is unknown terrority for me.

The git looks older?

ander@bananapif3:~/git/ParPar$ git branch -a
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/dev
  remotes/origin/interface_redesign
  remotes/origin/master
sander@bananapif3:~/git/ParPar$ git checkout origin/dev
Note: switching to 'origin/dev'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

On the dev branch (right?), the node-gyp rebuild does not give a (real) error, so good? Where is the parpar binary now?

Oh sorry, I should've given clearer instructions, but it looks like you figured it out. Thanks for the effort!

Oof, probably should use a smaller test size - can add something like -z1024 to the bench-gf16 command to hopefully make the bench run faster.

And, yes, bench-gf16 contains vector commands, so looks good?

sander@bananapif3:~/git/ParPar/test/bench$ objdump -d bench-gf16  | awk '{ print $3 }' | sort -u | grep -E "^v" | head -10
vadd.vv
vand.vi

[animetosho]

Thank you! That's some interesting results.

[sanderjo]

I wrote a RVV detector: https://github.com/sanderjo/anything_everything/blob/main/rvv_detector/rvv_detector.py

... which I brute-force ran on ~/git/ParPar. See results below with only the files that do contain RVV code.

Is this what you expected?

[animetosho]

The results roughly look right to me.

In terms of your script, I'm not sure if instructions starting with v are guaranteed to all be vector related. But if it's just a quick script for yourself, it's probably sufficient.
