Two papers about using GCC for virtual machines are also quite interesting. I think we are going to see more programs working in virtual machines, as the priorities shift from productivity to security and correctness. Managed code offers more flexibility than the native memory management hardwired into the CPU.
As for VLIW, we may see other attempts at getting it to the market. As the CPU frequencies are stuck around 2GHz, tricks that allow the CPU to do more per cycle are going to become more valuable. Good support in a free compiler is essential for making a competitive and open VLIW platform.

(It was a shame to see YARA stall. I really hoped that finally we'd be able to rid the world of reload...)

Not so sure: in the paper, they have a 4% average improvement in Spec2000 for x86, it'd be interesting to know the improvement when going from x86 to x86-64 mode.
And of course with 16 integer register instead of 8, the register allocator has then a far easier job..

(Of course sometimes you *have* to spill.)
The graph showing pretty much a complete absence of any execution-time
slowdowns was nice too.

Well the Power6 has a target of 4-5 GHz, so some are still trying to increase the clock frequency..

Please note that there are a wide variety of topics, not just IA64 ones. Abstracts can be viewed at the GCC Summit site, www.gccsummit.org
The copy of the proceedings on my people page will be vanishing shortly; it was intended solely for the printer.
