           Summary: MultiSource/Applications/viterbi slow on X86/PPC with
                    LLC
           Product: libraries
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Common Code Generator Code
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: sabre at nondot.org


The X86 LLC ratio for viterbi is .75, the CBE ratio is 1.0.
The PPC LLC ratio for viterbi is .74, the CBE ratio is 0.96

We need to find out why native X86/PPC is 25% slower than the CBE or GCC.
