How does clang 2.7 hold up in 2021?
For people who aren't aware, Proebsting's law states: Compiler Advances Double Computing Power Every 18 Years Which is to say, if you upgrade your compiler every 18 years, you would expect on average your code to double in performance on the same hardware. Let's C about this It occurred to me that I could try to do an experiment. I could take a modern compiler and compare performance of generated code - along with perhaps a few other metrics - vs a 20-year-old one. At least this was my initial intention; however I've long wanted to do another experiment which is to figure out how LLVM has ch...
