Clang Static Analyzer and the Z3 constraint solver (2022) (cambus.net)
As far as static analyzers are concerned, one of the most important point to consider is filtering out false positives as much as possible, in order for the reports to be actionable.

Ways to generate SSA (bernsteinbear.com)
Static Single Assignment is a program representation where each “variable” (though this term can be misleading) is assigned exactly once. Mostly the variables aren’t variables at all, but instead names for values—for expressions. SSA is used a lot in compilers. I’m making this page to catalog the papers I have found interesting and leave a couple of comments on them.

What would it take to add refinement types to Rust? (yoric.github.io)
A few years ago, on a whim, I wrote YAIOUOM. YAOIOUM was a static analyzer for Rust that checked that the code was using units of measures correctly, e.g. a distance in meters is not a distance in centimeters, dividing meters by seconds gave you a value in m / s (aka m * s^-1).
