| # This prepares a custom sysroot with our custom `alloc` instead of |
| # the standard one. |
| # |
| # This requires several hacks: |
| # - Unlike `core` and `alloc`, `std` depends on more than a dozen crates, |
| # including third-party crates that need to be downloaded, plus custom |
| # `build.rs` steps. Thus hardcoding things here is not maintainable. |
| # - `cargo` knows how to build the standard library, but it is an unstable |
| # feature so far (`-Zbuild-std`). |
| # - `cargo` only considers the use case of building the standard library |
| # to use it in a given package. Thus we need to create a dummy package |
| # and pick the generated libraries from there. |
| # - Since we only keep a subset of upstream `alloc` in-tree, we need |
| # to recreate it on the fly by putting our sources on top. |
| # - The usual ways of modifying the dependency graph in `cargo` do not seem |
| # to apply for the `-Zbuild-std` steps, thus we have to mislead it |
| # by modifying the sources in the sysroot. |
| # - To avoid messing with the user's Rust installation, we create a clone |
| # of the sysroot. However, `cargo` ignores `RUSTFLAGS` in the `-Zbuild-std` |
| # steps, thus we use a wrapper binary passed via `RUSTC` to pass the flag. |
| # |
| # In the future, we hope to avoid the whole ordeal by either: |
| # - Making the `test` crate not depend on `std` (either improving upstream |
| # or having our own custom crate). |
| # - Making the tests run in kernel space (requires the previous point). |
| # - Making `std` and friends be more like a "normal" crate, so that |
| # `-Zbuild-std` and related hacks are not needed. |
