Subject: [Qemu-devel] [PATCH] target-ppc: Fix vcmpbfp. Unordered Case
Date: Fri, 31 Oct 2014 11:39:54 -0500 [thread overview]
Message-ID: <1414773594-8014-1-git-send-email-tommusta@gmail.com> (raw)
Fix the implementation of Vector Compare Bounds Single Precision.
Specifically, fix the case where the operands are unordered -- since
the result is non-zero, the CR[6] field should be set to zero.
