            Bug ID: 64600
           Summary: arm-rtems ICE on valid code (-mcpu=xscale)
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: joel at gcc dot gnu.org

$ arm-rtems4.11-gcc --version
arm-rtems4.11-gcc (GCC) 5.0.0 20150114 (experimental)

Last hash per git: commit d4cbe45aae70e38c12f3cd7430427c98289d7882

The fix for 64460 is in place.

Attached test case compiles at -Os but not -O1 or -O2. 
-O2 without -mcpu=xscale also works.
