Clinging to Clang
summary
Clang serves as a usable cross‑compiler for Embedded Linux with concrete work: WebKit builds in 2297s vs 2838s (clang vs GCC), OpenEmbedded gets a meta‑layer called meta-clang, and the SDK exports CLANG_CC/CLANG_CXX. Clang provides clang-tidy/clang-format/static analyzer, compiler-rt, libc++/libc++abi and libunwind alternatives, and sanitizers; about 80–90% of packages compile, but Linux kernel and full glibc builds still require patches or a hybrid GCC/Clang toolchain.
