Rust to C compiler – 95.9% test pass rate, odd platforms

This is an update on the progress I have made on my Rust to C compiler. I am experimenting a bit with a new article format: instead of an overarching theme, this is more of a collection of smaller bits and pieces, sewn together.

So, the ability to just use a built-in emulated version of this intrinsic is amazing: this means I don’t need to fiddle around and find my own solution to this problem. For now, the plan is to get as close to standard-compliant C99(or maybe even ANSI C) as possible, and only use standard POSIX APIs(I need some threading support to properly initialise thread-locals). The main issue is that there exist some rather exotic r/lvalues which don’t map too well to C. They are quite hard to show without going into some more obscure features of Rust, like dynamically sized types.
