rust: new package This new package provides rustc, the compiler for the Rust programming language, built from source. Currently, only the host variant is built. The Rust compiler uses LLVM as its backend: a copy of LLVM source code is provided and CMake is used to build it. It is possible to use a pre-built external copy. When LLVM/clang will be available in Buildroot, it would be possible to benefit from this feature and thus decrease build time. LLVM is configured to generate code for x86, ARM, PowerPC and MIPS architectures. The Rust compiler uses Cargo as its build system and is written in Rust. Therefore this package depends on cargo-bin and rust-bin. The internal build process is as follows: 1. stage0 compiler, provided by rust-bin, is used to build stage1 compiler. 2. stage1 compiler builds the final Rust compiler (stage2 compiler) and the standard library for the host architecture. 3. the standard library for the target architecture is built. The target architecture to support is given by the GNU/LLVM target triple. Rust supports some predefined targets [1]. As the build system expects the triple to be in the form of <arch>-unknown-<system> and Buildroot toolchain wrapper uses <arch>-buildroot-<system>, the package Makefile uses $(RUST_TARGET_NAME) defined in the rustc package and uses it instead of $(GNU_TARGET_NAME). When compiling Rust code with this compiler, the generated program only depends on the target C library, as it is statically linked to the Rust standard library and any other code from Rust packages (a.k.a. "crates"). If the jemalloc package is selected, support for this memory allocator will be enabled in the target standard library. The menuconfig entry for rustc is also updated to expose this provider.
