How to view a file as if it was compiled with target_feature=+avx2,...?

[MadProbe]

I am doing development for code part of which is specifically optimized with avx2 under #[cfg(target_feature = "avx2")] and I want to see my file with the code as if I have compiled my project with -C target-feature=+avx2. How to do it? I am developing in VSCode BTW, if that may help to pin point exact actions for resolving this problem.

I don't think that's currently possible unfortunately.
