> Hello everyone! I removed the `register` keyword from `read_csr` function, which is used to check CPU vector length. Inside QEMU with RVV I see that the behavior is the same as with `register`. Furthermore, inside GDB I see that register used for `csrr vlenb` is `a0` with and without `register` keyword. With this fix `make hotspot` with latest clang used succeeded without any warnings.
