Subject: [PATCH] riscv: Fix warning in riscv_regno_ok_for_index_p
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The variable `regno` is currently not used in riscv_regno_ok_for_index_p(),
which triggers a compiler warning. Let's address this.

Fixes: 423604278ed5 ("riscv: Prepare backend for index registers")

gcc/ChangeLog:

	* config/riscv/riscv.cc (riscv_regno_ok_for_index_p):
	Remove parameter name from declaration of unused parameter.
