            Bug ID: 96232
           Summary: Failure to optimize bool pattern equivalent to minus 1
           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: ---

int f(bool x)
{
    return x ? 0 : -1;
}

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