Subject: [PULL 18/18] target/s390x: Exit tb after executing ex_value
Date: Thu, 7 Jul 2022 09:54:26 +0200 [thread overview]
Message-ID: <20220707075426.1163210-19-thuth@redhat.com> (raw)
In-Reply-To: <20220707075426.1163210-1-thuth@redhat.com>
From: Richard Henderson <richard.henderson@linaro.org>
When EXECUTE sets ex_value to interrupt the constructed instruction,
we implicitly disable interrupts so that the value is not corrupted.
Exit to the main loop after execution, so that we re-evaluate any
pending interrupts.
