* [Buildroot] [PATCH 0/2] Add support for more rust platforms @ 2021-05-18 20:54 Thomas Petazzoni 2021-05-18 20:54 ` [Buildroot] [PATCH 1/2] package/rustc: prepare for musl-based platforms support Thomas Petazzoni 2021-05-18 20:54 ` [Buildroot] [PATCH 2/2] package/rustc: add support for Tier 1 and Tier 2 platforms Thomas Petazzoni 0 siblings, 2 replies; 5+ messages in thread From: Thomas Petazzoni @ 2021-05-18 20:54 UTC (permalink / raw) To: buildroot Hello, This (small) patch series started from the patch from Nathaniel Husted enabling support for musl-based platforms in our Rust packaging. Unfortunately, the patch from Nathaniel was not entirely correct: indeed, not all CPU architectures have musl support in Rust, so simply replacing "depends on glibc" by "depends on glibc || musl" was not sufficient. Instead, Rust has a classification of platforms by how well they are supported: Tier 1 platforms, Tier 2 platforms with host tools, Tier 2 platforms without host tools, Tier 3 platforms. In order to make it easier to keep track of which platforms are supported, this patch series rewrites how package/rustc/Config.in.host declares which platforms are supported, to map directly with the Tier 1, Tier 2 with host tools and Tier 2 without host tools platforms. For the sake of simplicity, Tier 3 platforms are not supported at this point. With this patch series, 3 new glibc-based platforms are supported, and 13 new musl-based platforms are supported. The series is also available at: https://github.com/tpetazzoni/buildroot/commits/rustc-arches Thanks!

MORIN 1 sibling, 1 reply; 5+ messages in thread From: Thomas Petazzoni @ 2021-05-18 20:54 UTC (permalink / raw) To: buildroot 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.

The additional non-musl platforms are ARMv5TE, RISC-V > 64-bit and Sparc64. > > Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Applied to next, thanks. Regards, Yann E.
