--- Comment #16 from Jean-S=C3=A9bastien P=C3=A9dron <dumbbell@FreeBSD.org>=
 ---
The pull request to update the libc Git submodule in Rust was just merged:
https://github.com/rust-lang/rust/pull/39601

Thus all patches are in to build for and run on FreeBSD/aarch64.

The next step is asking upstream how to enable automatic creation of offici=
al
FreeBSD/aarch64 bootstraps.

In the meantime, it's probably possible we produce our own use it to build
packages of lang/rust-nightly, perhaps lang/rust too. For Cargo, I'm wonder=
ing
if we would need a devel/cargo-nightly. I'll play around that as soon as I =
can.

For sparc64, the patches are ready, but I can't get a working C++
cross-compiler: either I get compilation/link failures or the produced
executable segfaults. To be exact, I could obtain a working hello world with
base's libstdc++, but LLVM (built as part of the Rust build) requires libst=
dc++
4.7+.
