Hi,

  I keep getting this error whenever I send a
mail to gcc@gcc.gnu.org. Can "pupuru@kornet.net"
be removed from the list please?

Thanks,
Ranjit.

I *think* I know what the problem is - the arguments'
size is not being computed correctly - it does not
affect Linux, but it does Win32.

The relevant code in gcc/java/expr.c is:

  for (tem = method_args; tem != NULL_TREE; tem = TREE_CHAIN (tem))
    {
      int arg_bits = TREE_INT_CST_LOW (TYPE_SIZE_UNIT (TREE_TYPE (tem)));
#ifdef PARM_BOUNDARY
      arg_bits = (((arg_bits + PARM_BOUNDARY - 1) / PARM_BOUNDARY)
                  * PARM_BOUNDARY);
#endif
      args_size += (arg_bits / BITS_PER_UNIT);

      args = tree_cons (NULL_TREE, tem, args);
    }

I had written this a long time ago (GCC 3.2/3.3-ish)
when it *did* work correctly. In the current mainline,
I see that for an integer argument (i686-pc-linux-gnu),
TYPE_SIZE is 32, but TYPE_SIZE_UNIT is 4.

Have TYPE_SIZE and TYPE_SIZE_UNIT reversed their meanings
in recent times or was the original code wrong to
begin with?

I was an utter newbie to GCC at that time, so I could
very well have been grossly mistaken:

Thanks,
Ranjit.

That address doesn't seem to be on the gcc mailing list, nor any other
kornet.net address.  Perhaps somebody already removed it.

Strange. I also got the same error when I 
sent a mail to the java@gcc.gnu.org list.

It seems to be a person named "Hoe-Seong Ha":

I found the address on the java list, and removed it.
