Subject: [Qemu-devel] [PATCH 16/19] target-alpha: fix wrong usage of float64_eq_quiet()
Date: Tue, 12 Apr 2011 23:59:28 +0200	[thread overview]
Message-ID: <1302645571-20500-17-git-send-email-aurelien@aurel32.net> (raw)
In-Reply-To: <1302645571-20500-1-git-send-email-aurelien@aurel32.net>

On alpha, all NaN should trap during a comparison, not only sNaN. Fix
this by using float64_eq() instead of float64_eq_quiet().

Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
(cherry picked from commit 64990e0735007f75fe03123c1339366bcb496268)
