           Summary: negative shift count in build_constants_constructor
                    for 16 bit pointer targets
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: java
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: amylaar@gcc.gnu.org


Currently, we can't compile java/constants.c with -Werror for any target
with 16 bit pointers - such as h8300, m32c, m68hc11, pdp11 or stormy16 -
because of a negative shift in build_constants_constructor.

The amended patch bootstrapped & regtested successfully
(including check-target-libjava) on i686-pc-linux-gnu.
