From ab870fa106e0e3f48db2c5ef0507d107b1b41a21 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 5 Dec 2024 14:29:13 +0100 Subject: rust: add a bit operation module The bindgen supports `static inline` function binding since v0.64.0 as an experimental feature (`--wrap-static-fns`), and stabilizes it after v0.70.0. But the oldest version of bindgen supported by QEMU is v0.60.1, so there's no way to generate the binding for deposit64() which is `static inline` (in include/qemu/bitops.h). Instead, implement it by hand in Rust and make it available for all unsigned types through an IntegerExt trait. Since it only involves bit operations, the Rust version of the code is almost identical to the original C version, but it applies to more types than just u64.
