[Qemu-devel] [PATCH v4 4/6] target/arm/translate: ensure gen_goto_tb set


From: Alex Bennée
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

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.

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