Thanks for your hints, Filip. I will try the approach you suggested next time.

BTW, one thing I think need to clarify is that the performance result of 32-bit DFG I pasted before is for the comparison between DFG w/o and w/ this patch (i.e. both have DFG turned on).

Here's the comparsion between w/o DFG and w/ DFG after this change, tested on Linux ia32. We still have two cases failed to run (stanford-crypto-ccm produces wrong results and stanford-crypto-sha256-iterative crashes) and under investigations.

TEST                     COMPARISON            FROM                 TO             DETAILS
