            Bug ID: 110915
           Summary: vector version of `x == MIN & x > y` is not optimized
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: missed-optimization
          Severity: enhancement
          Priority: P3
         Component: tree-optimization
          Assignee: pinskia at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

Example:
```
#include <limits.h>

#define vector __attribute__((vector_size(sizeof(unsigned)*2)))

vector signed fs(vector signed x, vector signed y)
{
  vector signed t = x == INT_MIN;
  vector signed t1 = x > y;
  return t & t1;
}
vector signed fu(vector unsigned x, vector unsigned y)
{
  vector signed t = x == 0;
  vector signed t1 = x > y;
  return t & t1;
}

 signed f2_1( signed x,  signed y)
{
   signed t = x == INT_MIN;
   signed t1 = x > y;
  return t & t1;
}
```

I am filing this as I am fixing the pointer version (PR 96695) and don't want
to lose track of this either.
