[Bug c/53317] New: Conversion from __float128 to __int128

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53317

             Bug #: 53317
           Summary: Conversion from __float128 to __int128
    Classification: Unclassified
           Product: gcc
           Version: 4.6.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ahakkas@gmail.com


Conversion from __float128 to __int128 does not seem correct in gcc 4.6.3
version (gcc (GCC) 4.6.3 20120306 (Red Hat 4.6.3-2)). I am not aware if this
has been fixed in the later version. Here are a few examples: 

Input  = 0x00011002000E38000000080000000000   Result =
0x406F1802000E38000000080000000000
Correct result should be:                     Result =
0x406F1002000E38000000080000000000

Input  = 0x000115260000058B00022A4E00000164   Result =
0x406F3F6E000005EF00022A4E00000164
Correct result should be:                     Result =
0x406F15260000058B00022A4E00000164

Input  = 0x00014810000000000000000000033170   Result =
0x406F4810000331700000000000033170
Correct result should be:                     Result =
0x406F4810000000000000000000033170

Thanks.
