ts properly. Probably with an allocation builtin, not allowing for custom allocators? > supports properly. There is nothing in this simple macro that isn't "proper". There are no ways it can break (although I still feel it would be nice to have expressions macros, not only token macros). The only requirement is you write it yourself. C in general doesn't like to give you canned things. It has made such mistakes in the past (see large parts of libc) and has actually learned from it. > Plus all C workarounds for "safe" code tend to fall apart when teams scale above 1 team member, as it keeps being proven by endless industry and academic reports. You could absolutely implement C with managed memory. It just wouldn't be a good idea. Use other languages if you want these tradeoffs. Some of the most massive codebases in the world are C. (Often disguised as "C++ by experienced devs"). They are maintainable, protected investments, many decades old, and still in working order, precisely because a minimalistic language approach leads to modular APIs. It scales very well, and the "problem" might be mostly that the defect rate per line doesn't go down as the lines go up. But the best feature of these codebases is that they exist, because C enables independent development of subsystems much better than the intertwingled messes and dead ends that most "statically-systematic" approaches lead to on non-trivial scales. It's a huge boon that I don't have to think about rewriting interfaces using multiple inheritance or virtual inheritance or template insanity or SFINAE or unique_ptr or move semantics or rvalue references or static assertions or compile time evaluation, or the next fad around the corner, every 5 years.

aswell code will work on Ryzen with no illegal instructions. With these very textual and probably super easy-to-parse bitset data, you should also be able to answer the "what previous things are missing" question as well. You should be able to see some historical divides with ssse3/sse4a and fma3/4 et al. * * * About the completeness of the check: trust me it is complete enough to only include all extant processors that are supersets of Haswell. POPCNT plus AVX2 narrows it down a quite lot.
