            Bug ID: 104355
           Summary: Misleading -Warray-bounds documentation says "always
                    out of bounds"
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: documentation
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: redi at gcc dot gnu.org
  Target Milestone: ---

-Warray-bounds
      -Warray-bounds=3Dn
          This option is only active when -ftree-vrp is active
          (default for -O2 and above). It warns about subscripts
          to arrays that are always out of bounds. This warning
          is enabled by -Wall.

It's not true that it warns for "always out of bounds", as that implies no
false positives.=
