Series merged with style improvements, thanks. Please could you add a cross file in config/riscv/ for rv64gcv and use it in devtools/test-meson-builds.sh so we can test compiling with the vector extension? Another question about RISC-V maintenance in general, what do you think about other pending patches for RISC-V?
