hisi-riscv-rust v1.96.0-2 (riscv32imfc hard-float)

Custom Rust toolchain for the HiSilicon RISC-V family (WS63 + BS2X /
BS20·BS21·BS22), target riscv32imfc-unknown-none-elf (RV32IMFC_Zicsr,
hard-float ilp32f, no atomics) builtin — downstream builds need no
-Z build-std.

Multi-platform: linux x86_64/aarch64, macOS x86_64/aarch64, windows x86_64
(a tarball per host; the Windows build is best-effort).

Install (pick the tarball for your host; the rustup channel is hisi-riscv):

tar xzf hisi-riscv-rust-*-<your-host>.tar.gz
rustup toolchain link hisi-riscv "$PWD/stage2"

Each sysroot ships: rustc + cargo + rustfmt + clippy + rustdoc,
rust-analyzer-proc-macro-srv, rust-src, llvm-tools (rust-objcopy …),
and precompiled core/alloc for the target. Unix builds also include
rust-gdb / rust-lldb + pretty-printers.

ws63-rust v1.96.0-1 (riscv32imfc hard-float)

Custom Rust toolchain for the HiSilicon WS63 (RISC-V RV32IMFC_Zicsr,
hard-float ilp32f, no atomics). The riscv32imfc-unknown-none-elf
target is builtin — downstream builds need no -Z build-std.

Install:

tar xzf ws63-rust-*-x86_64-unknown-linux-gnu.tar.gz
rustup toolchain link ws63 "$PWD/stage2"

Sysroot ships: rustc + cargo + rustfmt + clippy + rustdoc,
rust-analyzer-proc-macro-srv (LSP proc-macro expansion), rust-src,
llvm-tools (rust-objcopy …), rust-gdb / rust-lldb + pretty-printers,
and precompiled core/alloc for the target.

ws63-rust 1.96.0 (riscv32imfc hard-float)

Custom rustc 1.96.0 (stable) with the HiSilicon WS63 target
riscv32imfc-unknown-none-elf (RV32IMFC_Zicsr, hardware single-float ilp32f, no atomics)
baked in as a builtin — build for it without -Z build-std (precompiled core/alloc included).

Host: x86_64-unknown-linux-gnu. sha256: 2880dc0b42e348c4d8cc5048dc7c7974bc143eeab95189fcba23c0e59b31aeaf
