It's public, but I doubt it still compiles against recent LLVM versions! I started it 8 years ago to get a better understanding how features like classes & operator overload would work in a JS-like language. It was really fun!

I remember that at the time there were very few resources on personality functions, even in the LLVM doc - I had to make a lot of research before finding your articles, which were extremely helpful!

I got reminded of them yesterday after someone pinged me on a Stack Overflow answer I made at the time, asking for an updated link; after I found your long-form article I figured it would be a good topic for HN as well :)

Mainly that exception handling doesn't have a single solution, even in GCC. I'm agreeing with you that this article only highlights one version of exception handling for one compiler.

There's also potential operating system involvement that's not really covered in this article.

“Standard C++” just specifies `throw` and `catch` (plus what happens when you traverse a block, nothrow declaration etc)

Every implementation has to do something to actually be standard C, and this is an example. It’s rather similar on other hardware, but as far as the standard goes that is irrelevant.

sjlj is still supported, at least on some platforms, e.g. MinGW.
