Subject: [PULL 23/31] accel/tcg: Un-inline icount_exit_request() for clarity
Date: Tue, 30 Jan 2024 09:01:13 +1000 [thread overview]
Message-ID: <20240129230121.8091-24-richard.henderson@linaro.org> (raw)
In-Reply-To: <20240129230121.8091-1-richard.henderson@linaro.org>
From: Philippe Mathieu-Daudé <philmd@linaro.org>
Convert packed logic to dumb icount_exit_request() helper.
No functional change intended.
