            Bug ID: 116713
           Summary: [SH] __builtin_prefetch can't be used for store queues
           Product: gcc
           Version: 14.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: olegendo at gcc dot gnu.org
  Target Milestone: ---

In some cases  __builtin_prefetch will be eliminated and thus it can't be
reliably used for SH4 store queue writes.
