Subject: [PATCH-for-8.0 2/3] softmmu: Restrict cpu_check_watchpoint / address_matches to TCG accel
Date: Tue, 28 Mar 2023 18:02:02 +0200	[thread overview]
Message-ID: <20230328160203.13510-3-philmd@linaro.org> (raw)
In-Reply-To: <20230328160203.13510-1-philmd@linaro.org>

Both cpu_check_watchpoint() and cpu_watchpoint_address_matches()
are specific to TCG system emulation. Declare them in "tcg-cpu-ops.h"
to be sure accessing them from non-TCG code is a compilation error.

Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
