[Qemu-devel] [PATCH 02/22] translate-all: remove redundant !tcg_enabled


From: Emilio G. Cota
Subject: [Qemu-devel] [PATCH 02/22] translate-all: remove redundant !tcg_enabled check in dump_exec_info
Date: Sun, 9 Jul 2017 03:49:54 -0400

This check is redundant because it is already performed by the only
caller of dump_exec_info -- the caller was updated by b7da97eef
("monitor: Check whether TCG is enabled before running the "info jit"
code").

Checking twice wouldn't necessarily be too bad, but here the check also
returns with tb_lock held. So we can either do the check before tb_lock is
acquired, or just get rid of it. Given that it is redundant, I am going
for the latter option.
