Subject: [PULL 08/34] replay: use CF_NOIRQ for special exception-replaying TB
Date: Fri, 11 Feb 2022 12:30:33 +1100	[thread overview]
Message-ID: <20220211013059.17994-9-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220211013059.17994-1-richard.henderson@linaro.org>

From: Pavel Dovgalyuk <pavel.dovgalyuk@ispras.ru>

Commit aff0e204cb1f1c036a496c94c15f5dfafcd9b4b4 introduced CF_NOIRQ usage,
but one case was forgotten. Record/replay uses one special TB which is not
really executed, but used to cause a correct exception in replay mode.
This patch adds CF_NOIRQ flag for such block.
