Now now, chess programs written to compete with other chess programs
need all the performance they can get. You could argue that he should
be using C with inline assembly (and probably another compiler than
GCC), but wouldn't it be kind of neat if a competitive and readable
chess program was written in Ada? It would be a feather in the hat for
Ada's low-level features, which is what this is all about.

I would ask the GCC team, after looking at the intermediate code. I'm
sure they're not content with merely having the compiler generate
correct code.
