             Bug #: 56778

           Summary: ICE on several benchmarks after r196775.

    Classification: Unclassified

           Product: gcc

           Version: 4.9.0

            Status: UNCONFIRMED

          Severity: normal

         Component: tree-optimization

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: ysrum...@gmail.com





We got ICE on several benchmarks that can be reproduced on the simple

test-case:

typedef struct {

  float a,b,c;

} S;



S * arr[100];



void bar (float *in[], int n)

{

  int i;

  for (i=0; i<n; i++)

    (*in)[i] = -arr[i]->b;

}



and compile on x86 with following options:



-march=core-avx2 -O3
