Hi Sasha,

I tested your change.  Unfortunately it breaks our port.  You need to fix Unsigned to

If you want to, you can move loading the bci in this bytecode behind the loop.

Could you please fix indentation of relocInfo::none in call_c? Should
be aligned to call_c.

Best regards,

Please review the patch that ports template interpreter to the
little-endian PowerPC64.
I have tested it on linuxppc64le.
I need a sponsor.
