Subject: [Qemu-devel] [PATCH 2/9] target/m68k: Replace DISAS_TB_JUMP with DISAS_NORETURN
Date: Fri, 11 May 2018 21:59:42 -0700	[thread overview]
Message-ID: <20180512045950.12386-4-richard.henderson@linaro.org> (raw)
In-Reply-To: <20180512045950.12386-1-richard.henderson@linaro.org>

We have exited the TB after using goto_tb; there is no
distinction from DISAS_NORETURN.
