Subject: [PULL 16/68] target/nios2: Split PC out of env->regs[]
Date: Tue, 26 Apr 2022 11:18:15 -0700	[thread overview]
Message-ID: <20220426181907.103691-17-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220426181907.103691-1-richard.henderson@linaro.org>

It is cleaner to have a separate name for this variable.
