[Qemu-devel] [PATCH v3 03/15] target/sh4: do not include DELAY_SLOT_TRUE


From: Aurelien Jarno
Subject: [Qemu-devel] [PATCH v3 03/15] target/sh4: do not include DELAY_SLOT_TRUE in the TB state
Date: Wed, 10 May 2017 20:26:24 +0200

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.
