The abs1 function in ops_sse.h only works sorrectly when the result fits in a signed int. This is fine most of the time because we're only dealing with byte sized values. However pcmp_elen helper function uses abs1 to calculate the absolute value of a cpu register. This incorrectly truncates to 32 bits, and will give the wrong anser for the most negative value. Fix by open coding the saturation check before taking the absolute value. Signed-off-by: Paul Brook <paul@nowt.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |
