            Bug ID: 44167
           Summary: libunwind assumes all powerpc platforms have altivec
                    and FPU
           Product: Runtime Libraries
           Version: trunk
          Hardware: Other
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: libunwind
          Assignee: unassignedbugs at nondot.org
          Reporter: chmeeedalf at gmail.com

UnwindRegistersSave.S includes unconditional saving and loading of floating
point registers and altivec registers.  However, not all PowerPC platforms have
FPU or Altivec.  The PowerPC e500 uses a non-standard FPU, the SPE, which uses
the GPRs, and has no altivec.  The PowerPC e500mc and e5500 have a FPU but no
Altivec.
