Subject: [Qemu-devel] [PATCH v2 2/4] target-i386: Move TCG initialization check to tcg_x86_init()
Date: Fri, 18 Sep 2015 16:38:14 -0300 [thread overview]
Message-ID: <1442605096-14103-3-git-send-email-ehabkost@redhat.com> (raw)
In-Reply-To: <1442605096-14103-1-git-send-email-ehabkost@redhat.com>
Instead of requiring cpu.c to check if TCG was already initialized,
simply let the function be called multiple times.
Suggested-by: Igor Mammedov <imammedo@redhat.com>
