83# The `html_logo_url` and `html_favicon_url` forms of the `doc` attribute
84# can be used to specify a custom logo. However:
85# - The given value is used as-is, thus it cannot be relative or a local file
86# (unlike the non-custom case) since the generated docs have subfolders.
87# - It requires adding it to every crate.
88# - It requires changing `core` which comes from the sysroot.
89#
90# Using `-Zcrate-attr` would solve the last two points, but not the first.
91# The https://github.com/rust-lang/rfcs/pull/3226 RFC suggests two new
92# command-like flags to solve the issue. Meanwhile, we use the non-custom case
93# and then retouch the generated files.

207# This prepares a custom sysroot with our custom `alloc` instead of
208# the standard one.
209#
210# This requires several hacks:
211# - Unlike `core` and `alloc`, `std` depends on more than a dozen crates,
212# including third-party crates that need to be downloaded, plus custom
213# `build.rs` steps. Thus hardcoding things here is not maintainable.
214# - `cargo` knows how to build the standard library, but it is an unstable
215# feature so far (`-Zbuild-std`).
216# - `cargo` only considers the use case of building the standard library
217# to use it in a given package. Thus we need to create a dummy package
218# and pick the generated libraries from there.
219# - Since we only keep a subset of upstream `alloc` in-tree, we need
220# to recreate it on the fly by putting our sources on top.
221# - The usual ways of modifying the dependency graph in `cargo` do not seem
222# to apply for the `-Zbuild-std` steps, thus we have to mislead it
223# by modifying the sources in the sysroot.
224# - To avoid messing with the user's Rust installation, we create a clone
225# of the sysroot. However, `cargo` ignores `RUSTFLAGS` in the `-Zbuild-std`
226# steps, thus we use a wrapper binary passed via `RUSTC` to pass the flag.
227#
228# In the future, we hope to avoid the whole ordeal by either:
229# - Making the `test` crate not depend on `std` (either improving upstream
230# or having our own custom crate).
231# - Making the tests run in kernel space (requires the previous point).
232# - Making `std` and friends be more like a "normal" crate, so that
233# `-Zbuild-std` and related hacks are not needed.
