# 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.
