             Bug #: 56603
           Summary: Different _MM_HINT_TX values from ICC
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: hjl.tools@gmail.com
                CC: ubizjak@gmail.com


GCC defines:

/* Constants for use with _mm_prefetch.  */
enum _mm_hint
{
  _MM_HINT_T0 = 3, 
  _MM_HINT_T1 = 2, 
  _MM_HINT_T2 = 1, 
  _MM_HINT_NTA = 0
};

However, ICC defines

_MM_HINT_T0 = 1
_MM_HINT_T1 = 2
_MM_HINT_T2 = 3
_MM_HINT_NTA = 0

It seems a typo in GCC.
