            Bug ID: 116163
           Summary: RFE: add a linting tool for DegaGnu tests
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Keywords: internal-improvement
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dmalcolm at gcc dot gnu.org
  Target Milestone: ---

Sam's been doing great work lately fixing malformed dg directives in our
testsuite.

We chatted briefly on IRC about maybe having a linting tool to automate
detection of the common mistakes, so that we can prevent categories of mistakes
going forward.

Filing this RFE to capture this idea, and to give a place to record ideas for
things it could check.

Could probably be done as a simple Python 3 script under "contrib".
