Subject: [Qemu-devel] [PATCH 03/14] target/sh4: do not include DELAY_SLOT_TRUE in the TB state
Date: Tue,  2 May 2017 00:10:35 +0200	[thread overview]
Message-ID: <20170501221046.9369-4-aurelien@aurel32.net> (raw)
In-Reply-To: <20170501221046.9369-1-aurelien@aurel32.net>

DELAY_SLOT_TRUE is used as a dynamic condition for the branch after the
delay slot instruction. It is not used in code generation, so there is
no need to including in the TB state.
