Subject: [Qemu-devel] [PATCH 06/11] target-i386: use floatx80 constants in helper_fld*_ST0()
Date: Sun, 15 May 2011 16:13:16 +0200 [thread overview]
Message-ID: <1305468801-6015-7-git-send-email-aurelien@aurel32.net> (raw)
In-Reply-To: <1305468801-6015-1-git-send-email-aurelien@aurel32.net>
Instead of using a table which doesn't correspond to anything from
physical in the CPU, use directly the constants in helper_fld*_ST0().
