Do you know why it is alphabetical instead of declaration order?

No idea but we should ask

I got curious and looked around. Could it be this? cs.android.com/android/plat...

Thanks! Finally I have a good reason to rename all my variables to v01, v02, v03 etc... 😄 An excellent read, as always! 👏

x, y, and z are excellent choices :D

scary! Is it only android thing?

I will be very very careful when naming fields in protocol buffers going forward. Also be right back after having a couple of things I defined recently 😫.

If they all fit in the same cache line, no renaming necessary 😁

I sure hope this blog doesn't result in folks sacrificing readability in their projects for these small gains 😭

Amazing but please 🙏 put a disclaimer somewhere that while this sort of micro optimization can be beneficial in things like graphics & high frequency problems, it's not something your average dev should worry about I can already see the PRs from junior devs: "Romain Guy said to rename variables" 😂

Reminds me when lots of Android developers got rid of Enums at some point

Ah yes. The enum-gate of yore. I remember that era fondly

Thank you for your blog post. I often read that cache misses can drop performance. Which you also face when using data structures like linked lists (pointer chasing). But was not aware that this can reduce the performance so much.

Romain what have you done
