           Summary: Power PC setjmp broken on Altivec machines
           Product: Tools
           Version: unspecified
          Platform: powerpc
        OS/Version: RTEMS
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Newlib
        AssignedTo: joel.sherrill at oarcorp.com
        ReportedBy: norume at aps.anl.gov

The Power PC version of setjmp/longjmp in newlib-1.15.0 does not check that the
Altivec unit is enabled before attempting to save/restore.  A processor
exception results.

Till Straumann has sent a patch in a previous mailing list message, but the
patch hasn't seemed to make it into the patch file(s) on the RTEMS server.
