Amount of bits is not an issue here at all, for example V8 already runs on x86-64 just fine.
Despite confusingly similar names ia32 and IA64 (Itanium) are *very* different architectures. I'd say generating efficient code for IA64 is much harder because compiler has to carefully schedule instructions in instruction bundles (IA64 is VLIW) to saturate execution units and avoid dreadful stalls. [though I heard that newest Itanium micro-architecture actually is more forgiving to poor scheduling and is capable of a good built-in out-of-order execution, but I am not closely following this things so I might be wrong] Vyacheslav Egorov On Sat, Apr 27, 2013 at 4:50 AM, <[email protected]> wrote: > Hi Folks, > > I'd like to spearhead a port to IA64 on OpenVMS, which does not support > IA32 subset.
