I dunno yet. Didn't seem to be lot's o' info in there
on the specifics of that. :^)
I would assume they would want to use the IA-64 engine
for IA-32 instructions. The IA-64 logic fetches instructions
in bundles of 3. Probably the IA-32 decode logic
tries to schedule each IA-32 instruction, as an
equivalent set of IA-64 instructions within a bundle.
Or perhaps they have separate logic.
