            Bug ID: 64461
           Summary: bad assembly generated for Coldfire targets
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org

Preprocessed RTEMS source which produces the error

Fails at -O1, -O2, and -Os. All RTEMS Coldfire BSPs appear to be failing to
build. I have not looked through all build logs yet to give a complete list of
CPU models impacted but all are Coldfires. For sure, 5235 and 5282 do this.
