[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 |
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.
