Subject: [Qemu-devel] [PATCH 1/9] target-i386: Move TCG initialization check to tcg_x86_init()
Date: Fri,  6 May 2016 15:11:24 -0300	[thread overview]
Message-ID: <1462558292-2126-2-git-send-email-ehabkost@redhat.com> (raw)
In-Reply-To: <1462558292-2126-1-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>
