            Bug ID: 67199
           Summary: ICE with compile bug related to vector_size
           Product: gcc
           Version: 4.9.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: zhongyunde at huawei dot com
  Target Milestone: ---

testcase:

__attribute__ ((vector_size (16))) g_73 = {0x15FE687EL, 0x5827DF98L,
0xF8411272L, 0x235E695EL};
__attribute__ ((vector_size (16))) g_1124;

int func_1(void)
{  
    __attribute__ ((vector_size (16))) l_1117 = {0x15FE688EL, 0x5827DF98L,
0xF8411272L, 0x235E695EL};
    __attribute__ ((vector_size (16))) zhong = ( g_73 <= g_73);
         g_1124 = (((g_73 < l_1117) == (zhong)) << 9)    ;

    return 0;
}

the following issue can be reproduced  with -O2 when the gcc built on 64 bits
system.
