OK, after spending a couple of hours learning powerpc assembly and the
gcc asm constraints I think that I have something that might be what is
needed for powerpc. Unfortunately it doesn't work correctly yet, but
looking at the output of --verbose I get the impression that we are
almost there. Here are the last 15 lines for sablevm --verbose Hello:

[verbose class: creating "[Ljava/util/Hashtable$HashEntry;"]
[verbose class: loading "java/util/StringTokenizer"]
[verbose class: loading "java/util/Enumeration"]
[verbose class: creating "[Ljava/lang/String;"]
[verbose class: loading "java/lang/StringBuffer"]
[verbose class: loading "java/lang/VMSecurityManager"]
[verbose class: loading "java/util/WeakHashMap$WeakBucket$WeakEntry"]
[verbose class: loading "java/io/BufferedInputStream"]
[verbose class: loading "java/io/FilterInputStream"]
[verbose class: loading "java/io/InputStream"]
[verbose class: loading "java/io/FileInputStream"]
[verbose class: loading "java/io/FileDescriptor"]
[verbose class: loading "java/lang/SecurityException"]
java/lang/ExceptionInInitializerError
[verbose gc: total gc time = 0 sec 0 usec]

Attached are my versions of the above files. If there is someone with
some powerpc knowledge on the list then I would highly appreciate it if
you could take a look.

Have to get some sleep now.

Cheers,
