Best Gcc for IA64?

[Seima Rao]

Hi,

    I want to try out the full IA64 contribution to gcc.

    Please advise as to which gcc is sufficient?

    p.s. I am specifically looking for sw pipelining,
           global instr sched, interprocedural reg alloc,
          "the full VLIW works", etc.

Sincerely,
Seima Rao.
