Where can I find the instruction sets for G4/G5? In particular, I want
to find out whether the instructions exist for, and the timings of:

32 bit integer * 32 bit integer = 32 bit integer
32 * 32 = 64
etc, and the same for floating point.

Look at the Motorola website. You're wanting stuff that will be covereed
(probably in more detail than you realized was possible...) by one of
sevearl PowerPC tech books, all of which can be had for the asking (or
at least, they could when I got mine) on the website. Sorry I can't be
more specific than that, but it's been a while since I tried to dig up
such information.

As an alternative to downloading the relevant manuals from the Freescale
and/or IBM WWW sites, there's a handy dandy ISA reference in the Help
menu of Shark (download and install the latest CHUD tools if you haven't
already).
