           Summary: bytecode created with gcj -C doesn't cache lookup from
                    synthetic class$ member
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: java
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: jsturm at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: all
  GCC host triplet: all
GCC target triplet: all

Given the following source file:

class A {
    Class a() {
        return A.class;
    }
}

gcj generates the following bytecode:

  0: ldc #31=<String "A">
  2: invokestatic #33=<Method A.class$ (java.lang.String)java.lang.Class>
  5: areturn

whereas other java compilers (e.g. jikes) generate similar to:

  0: getstatic #13=<Field A.class$A java.lang.Class>
  3: dup
  4: ifnonnull 18
  7: pop
  8: ldc #14=<String "[LA;">
 10: iconst_0
 11: invokestatic #19=<Method A.class$ (java.lang.String,boolean)java.lang.Class  
 14: dup
 15: putstatic #13=<Field A.class$A java.lang.Class>
 18: areturn

Note the A.class$A synthetic field which is absent from gcj output.

The lossage is particularly noticable in libjava.lang/SyncTest.java.
