// Note: the following two genrules and this host binary are working together.
//
// gen_riscv64_to_x86_64_intrinsics is C++ program, generated by python script,
// which does not accept any inputs and produces berberis/intrinsics/intrinsics.h
//
// Other modules are not supposed to use gen_riscv64_to_x86_64_intrinsics, they should only
// depend on libberberis_intrinsics_gen_asm_impl_headers_riscv64_to_x86_64
//
// So with 64-bit RISC V headers we have two-step operation:
//
//   gen_intrinsics
//   -> text_asm_intrinsics_process_bindings-inl.h
//      -> gen_riscv64_to_x86_64_intrinsics
//         -> libberberis_intrinsics_gen_asm_impl_headers_riscv64_to_x86_64
//
// Compare to single-step generation of common headers:
//
//   gen_intrinsics
//   -> libberberis_intrinsics_gen_public_headers_riscv64_to_x86_64
