The first time I think I saw the idea was [0], but I don't know if this is the post that got linked in the discussion threads. Rust didn't have fuel at all until after my changes, and I don't think it's necessary to use it as a limit unless you're letting the optimizer run on the optimizer's output until it stops changing. The number of optimizations Rustc can run is already finite because it doesn't do so. nonetheless, the idea isn't original to us. 0: http://blog.ezyang.com/2011/06/debugging-compilers-with-optimization-fuel/ http://blog.ezyang.com/2011/06/debugging-compilers-with-opti...
