<pre>This is correct. Targeting the floating-point extensions doesn't necessarily
mean you are using the hardfloat ABIs. To ensure that floating-point arguments
are passed in the floating-point registers for rv64g be sure to also pass to
clang the option `-mabi=lp64d`. I believe you can now also pass the option
--target=riscv64-linux and you'll implicitly get the `march` and `mabi` options
that you intended, and the values will be passed in the floating-point
registers (might require compiling clang from recent sources).</pre>
