Subject: [PATCH 25/33] accel/tcg: Un-inline icount_exit_request() for clarity
Date: Sun, 28 Jan 2024 14:42:05 +1000	[thread overview]
Message-ID: <20240128044213.316480-26-richard.henderson@linaro.org> (raw)
In-Reply-To: <20240128044213.316480-1-richard.henderson@linaro.org>

From: Philippe Mathieu-Daudé <philmd@linaro.org>

Convert packed logic to dumb icount_exit_request() helper.
No functional change intended.
