Subject: [Qemu-devel] [PATCH v4 4/6] target/arm/translate: ensure gen_goto_tb sets exit flags
Date: Thu, 13 Jul 2017 15:19:26 +0100 [thread overview]
Message-ID: <20170713141928.25419-5-alex.bennee@linaro.org> (raw)
In-Reply-To: <20170713141928.25419-1-alex.bennee@linaro.org>
As the gen_goto_tb function can do both static and dynamic jumps it
should also set the is_jmp field. This matches the behaviour of the
a64 code.
Signed-off-by: Alex Bennée <alex.bennee@linaro.org>

v4
- set s->is_jmp = DISAS_TB_JUMP in both cases
