How much C have you written, and how much has gone through a high-performance optimizing compiler?

I don't know. Quite a bit - maybe written 300K lines and deleted > 200K lines. Most of it was compiled by gcc -O2 and/or MSVC. I've never relied on vectorization or used a lot of intrinsics, though.

I'm honestly quite surprised you've never run into surprising behavior caused by the optimizer handling undefined behavior…

Not that I'm aware of it.
