[Bug java/26007] New: initialized final static data should go in .rodata, not .data

[Bug java/26007] New: initialized final static data should go in .rodata, not .data

[green at redhat dot com]

For the following code...

public class b
{
  public static final int FOOBAR = 555;
}

..I would expect to see FOOBAR in .rodata.  However gcj currently places this
in .data.

If you poke through the .jar.so files we have in Fedora Core you'll see big
chunks of .data that should actually .rodata.

Note there are ticks for final static data to be changed IIRC.  I don't know
how useful they are or if they really are valid.

If you fix this, you need to also make sure the Method.set* never modifies the
data under any circumstances.  Attempts at modification will result in SIGSEGV
which is usually converted to NPE.  The real exception should probably be
IllegalAccessException if modification is attempted.

put it to .rodata is very useful to embebed system,this will release many
memory useage.
