            Bug ID: 90978
           Summary: A suspicious code in df-scan.c since r160348
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: marxin at gcc dot gnu.org
                CC: hubicka at gcc dot gnu.org
  Target Milestone: ---

clang-static-analyzer reports the following projects:

$ cat -n gcc/df-scan.c | less

  3791        struct df_scan_problem_data *problem_data
  3792          = (struct df_scan_problem_data *) df_scan->problem_data;
  3793          gcc_unreachable ();
  3794        df->exit_block_uses = BITMAP_ALLOC (&problem_data->reg_bitmaps);
  3795        changed = true;

Is the gcc_unreachable a desirable code?
