             Bug #: 56236

           Summary: incorrect debug info for decltype(nullptr)

    Classification: Unclassified

           Product: gcc

           Version: 4.6.2

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: debug

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: chihin...@oracle.com





g++ does not resolve decltype(nullptr) to base type nullptr_t, instead it

generate following: 



  < 1><0x000005d3>    DW_TAG_unspecified_type

                      DW_AT_name                  "decltype(nullptr)"



g++ should generate something like this:



< 1><0x000005d3>    DW_TAG_base_type

                      DW_AT_name                  "nullptr_t"

                      DW_AT_encoding              DW_ATE_boolean

                      DW_AT_byte_size             0x00000004



main() {

    int i;

    decltype(nullptr) np;



    np = 0;

    i = sizeof(np);

}
