Subject: [Qemu-devel] [PATCH v2 20/20] target-i386: switch to softfloat
Date: Wed, 20 Apr 2011 12:12:09 +0200 [thread overview]
Message-ID: <1303294329-22634-21-git-send-email-aurelien@aurel32.net> (raw)
In-Reply-To: <1303294329-22634-1-git-send-email-aurelien@aurel32.net>
This increase the correctness (precision, NaN values, corner cases) on
non-x86 machines, and add the possibility to handle the exception
correctly.
