Hi. This package claims to support x32 ABI but there is no rust-1.47.0-x32-unknown-linux-gnu.tar.xz in /usr/portage/disfiles.
Comment 1 Henrik 2021-06-07 20:39:04 UTC
I can confirm it is still broken with 1.52.1 as well as dev-lang/rust for x32
Comment 2 Oleh Kravchenko 2021-08-24 16:03:59 UTC

Comment 3 Steven Newbury 2022-05-04 12:30:08 UTC
The upstream rust binary distribution *does* support x32 (x86_64-unknown-linux-gnux32) but as a target only, and requires the x32 rust-std (rustlib) component to be installed. The toolchain itself is amd64 only.

For the purpose of bootstrapping a native x32 Rust toolchain, this enough.  Patches follow...

WIP patch to build native x32 rust toolchain

This is WIP because -system-bootstrap isn't complete.  It currently only works with system-bootstrap, although both dev-lang/rust-bin (amd64) and dev-lang/rust (x32) both work to bootstrap.

Also, only tested with system-llvm.

To get !system-boostrap working requires adding the x32 rustlib matching the rust release used for internal bootstrapping  as I did for rust-bin.

rust-bin ebuild patch adding x32 target rustlib

Apologies, this version works for both when x32 is multilib_is_native and when it isn't.  Suffering from apparent brain failure.
