Static analysis/tracing absolutely can do a bunch of that kind of thing, particularly catching trivial cases.

But I think it's still a pretty important upgrade when those things are being checked by the compiler, for free, with guarantees, as part of every build, rather than using some side-tool that may be proprietary, deliver oodles of false positives, and so on.

What I mean is just fix that so it works. If you have split stacks the one for data doesn't have to track function call chains.

The advantage of using analysis tools is you only pay for that once. Not with every compile. And the tools are smarter than Rust. You also don't have safe vs unsafe code like you do with Rust.

You wouldn't just need split stacks for this, you'd need a spaghetti stack with some kind of heap allocation for frames. At which point perf goes out of the window already.

If you are using gcc, clang or vc++, to certain extent that is part of the compiler.

Just like C, following the UNIX principle, had compiler, assembler, linker, makefile, and linter since 1979. But people kept forgetting about the last piece of the puzzle and now it is a pain to bolt into existing code.
