From b7da97eef74bf834be244de0796ccb01db3985c9 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 26 Apr 2017 06:11:47 +0200 Subject: monitor: Check whether TCG is enabled before running the "info jit" code The "info jit" command currently aborts on Mac OS X with the message "qemu_mutex_lock: Invalid argument" when running with "-M accel=qtest". We should only call into the TCG code here if TCG has really been enabled and initialized.
