Subject: [Qemu-devel] [PULL 1/6] target-sh4: add flags markups for FP helpers
Date: Sun, 13 Sep 2015 23:18:40 +0200 [thread overview]
Message-ID: <1442179125-29608-2-git-send-email-aurelien@aurel32.net> (raw)
In-Reply-To: <1442179125-29608-1-git-send-email-aurelien@aurel32.net>
Most floating point helpers can trigger an exception, but don't change
the globals. Mark these helpers as TCG_CALL_NO_WG.
