            Bug ID: 112425
           Summary: Invalid SARIF output when column number is zero
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dmalcolm at gcc dot gnu.org
  Target Milestone: ---

We use column number == 0 to mean "the whole line".

As noted in:
  https://gcc.gnu.org/pipermail/gcc-patches/2023-November/635446.html
SARIF requires column numbers to be >= 1

We should simply omit the attribute for such cases.
