           Summary: unrecognizable insn on simple Java code
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: java
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: bothner at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu

jc1 crashes with an "unrecognizable insn" when compiling the
following code with -O:

class Type { int size; }

public class Dup
{
  public void emitDup (int size, int offset) {  }

  public void emitDup (Type type)
  { emitDup(type.size > 4 ? 2 : 1, 0);  }
}

This is simplified from Kawa, which fails to build
because of this.

This has been failing for a while on the mainline, but
it used to work.
