Thomas, All,
On 2021-05-18 22:54 +0200, Thomas Petazzoni spake thusly:
> This commit reworks how BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS is
> defined to more clearly map with the list of platforms supported by
> Rust as listed at
> https://doc.rust-lang.org/nightly/rustc/platform-support.html. Indeed,
> the situation is not as simple as a list of architectures, all
> supported for both glibc and musl.
>
> So instead, we take the approach of directly mapping with what's
> described at
> https://doc.rust-lang.org/nightly/rustc/platform-support.html, which
> means:
>
> * A list of Tier 1 platforms (in fact just 3 platforms)
>
> * A list of Tier 2 platforms with host tools (i.e where rustc and
> cargo themselves are available for the target, something that isn't
> relevant for Buildroot)
>
> * A list of Tier 2 platforms with no host tools support.
>
> For each platform, we add as a comment its Rust tuple name, as listed
> at https://doc.rust-lang.org/nightly/rustc/platform-support.html, and
> then the corresponding Buildroot architecture/libc dependency.
>
> This is obviously more verbose than it was, but it is also a lot
> easier to maintain.
>
> With this, a total of 16 new platforms are supported, 13 of which are
> musl-based. The additional non-musl platforms are ARMv5TE, RISC-V
> 64-bit and Sparc64.

Applied to next, thanks.
