I can't get this to fail either on the tip of the trunk or r205320.
Are you still seeing this failure?

Can you include -v on your command line. It'd also be helpful if you could
include the intermediates generated by -save-temps.

--- Comment #6 from Jeffrey A. Law <law at redhat dot com> ---
Thanks. I've managed to reproduce the failure using those intermediate files.
However, I haven't managed to trigger the failure directly from source.
What's happening is we're getting into expand_shift_1:
Breakpoint 3, expand_shift_1 (code=LSHIFT_EXPR, mode=V8QImode,
shifted=0x200000000416e0e0, amount=0x2000000004010410, target=0x0, unsignedp=0)
The amount is (const_int 1)
V8Q8mode isn't a valid shift mode for the ia64 target (mode iterator for the
shifts uses VECINT24). Since there isn't a pattern for this, no libcall and
the generic bits don't know how to synthesize the shift, we trip the assertion
and die.
We get into this code trying to expand:

Clearly expanding a V8QImode multiply using a shift is a bad idea on Itanic.
What I don't see is how to stop the code form using shifts like this.
Regardless, the bug is confirmed, but given it's Itanic, it's certainly not
worthy of P1 status.
