           Summary: APInt::toString prints extra digits when radix != 10 and
                    bitwidth > 64
           Product: libraries
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Support Libraries
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: rspencer at reidspencer.com


The rather naive implementation of APInt::toString for radix!=10 and bitwidth >
64 causes it to print more digits than the bit width of the APInt specifies. The
algorithm prints whole words, even if only a few bits of the highest order word
are used. It needs to not do this.
