Ah, thanks, that works.
How can support for behavior be detected?
The intrinsic spec says:
> The `__riscv_v_intrinsic` macro is the C macro to test the compiler's support

and recommends using:
```c
#ifdef __riscv_v_intrinsic
#include

I guess it should be `__attribute__((target("arch=+zv

This feature is quite important, without it we can't compile in RVV by default
