            Bug ID: 109324
           Summary: Genrecog reports "source missing a mode?" for H8
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Keywords: build
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jdx at o2 dot pl
  Target Milestone: ---
            Target: h8300-elf

Unfortunately, I barely understand .md files, but I think genrecog is a bit
overzealous. It would be nice if these warnings could be muted somehow.
