          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

The code is never used and in fact is wrong especially for the 32_64 version, for example the nonSpeculativeBasicArithOp may require 6 GPRs while there are only 5 available on X86. So just remove such code to avoid potential confusions.

Patch forthcoming.
