lwi is a macro defined in arch.inc, lis and li are simplified
mnemonics defined in appendix F of the Programming Environments
manual. I'll agree that it is annoying that really useful information
like this is hidden away in an appendix, but that's IBM for you :-/
I would be interested to know what Motorola mnemonics are missing. Not
that we could do anything about it, this is would be a matter for the
GCC team to fix.
