Subject: [PATCH 17/17] target/riscv: Remove gen_get_gpr
Date: Thu,  8 Jul 2021 21:26:08 -0700	[thread overview]
Message-ID: <20210709042608.883256-18-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210709042608.883256-1-richard.henderson@linaro.org>

This function is now unused.
The corresponding gen_set_gpr function is still in use.
