i1 true ^= -1 in DAG matcher?
Hello,
It looks like that in the DAG matcher, the DAG has a xor with '-1' for
checking a true value vector
for instance,
%cmp4.i = icmp ne <8 x i32> %6, %5
%7 = xor <8 x i1> %cmp4.i, <i1 true, i1 true, i1 true, i1 true, i1 true, i1
true, i1 true, i1 true>
[use of %7]
results in vector of '-1' in the DAG. This also seems the reason why
