There seems to be some formatting applied to the stb_image.h in this PR. It's better to use the original header from upstream without changes

[arch-btw]

Oh yes, I see what you mean!
Is it possible by any chance that the original PR had custom formatting?

I'm just wondering because I checked every commit in the upstream repo starting at 2.28 (and the few commits leading up to it) and non of them match the file that we currently have in llama.cpp.

Then I verified the dev branch of upstream, but it doesn't match our current file either.

I also checked the shasum on this pull request and it matched the latest shasum of upstream:
594c2fe35d49488b4382dbfaec8f98366defca819d916ac95becf3e75f4200b3

Here are the steps that I took for this pull request:

1. Fork llama.cpp without making changes
2. Download stb_image.h from upstream
3. Delete stb_image.h from fork
4. Add stb_image.h to my fork without making any changes
5. Submit merge request

Feel free to let me know if I'm misunderstanding or how to proceed :)
Thank you!

Ah, you are right. I got confused.

Need to exclude stb_image.h from the editor config CI before merging
