            Bug ID: 95433
           Summary: Failure to completely optimize simple compare after
                    operations
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gabravier at gmail dot com
  Target Milestone: ---

auto f(int x)
{
    return (2 * x) + 5 == 3;
}

This can be optimized to `x == -1`. This transformation is done by LLVM, but
not by GCC.
