Subject: target-ppc: Fix vcmpbfp. Unordered Case
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4007b8de6e1012675672d6e6e4fc08633b3a0023;p=qemu.git

target-ppc: Fix vcmpbfp. Unordered Case

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.
