Rust compiler documentation / same results on different OSs?

[VonDerWelt]

Where can I read about the internals of the rust compiler ?

How is it to be assured that compilation on different OSs works with the same results (Linux/Windows) ?

By running test suits on every plattform. This is the reason Rust has different tiers of support. Rust internal tests and tests for crates on crates.io are run on all tier 1 targets.
