Subject: [PATCH V16 0/7] Rust Support for powerpc
Date: Wed, 20 May 2026 12:16:22 +0530 [thread overview]
Message-ID: <20260520064630.1785283-1-mkchauras@gmail.com> (raw)
Enable experimental rust support for ppc64le and ppc32be. The patch for
ppc32 has been provided by Link Mauve[1] and ppc64le support[2] has been
merged over it. ppc32 needs some toolchain fixes mentioned in the patch
`rust: Add PowerPC support` and the discussion for that is done here[1].
This has been tested on
- powernv9 hardware
- pseries P11 hardware
- pseries(9, 10) qemu
- powernv(9, 10) qemu
- rustdoc on x86 and powerpc64le
- rusttest on x86 and powerpc64le
We are actively working with our LLVM team to get the target for ppc,
ppc64 and ppc64le in the rust compiler.
