I'm sure they worked hard to make sure it sounded that way.  It's a big change, for sure. Some features look borrowed from processors such as MIPS R8000 and of course Alpha, since they had to buy out Alpha to settle patent infringments. The news media have been pretty quiet lately about the work which is surely going on under NDA's.  Not even the kind of speculation which you might think would feed off the situation; e.g. will gcc, linux, Monterey be ready for prime time before Windows, or will mass production be held until Windows is ready?  It looks clear now that they don't plan for IA64 to  displace IA32 soon, except in situations like the SGI parallel machines.

You can, but you have to build a cross-compiler first and, depending
on which OS you want to target, such a cross compiler may be more or
less challenging to build.  See the CrossGCC FAQ for (not too many)
details, and feel free to ask questions at the crossgcc mailing list.

Hi
Can i use gcc to compile ia64 code on ia32 platform.If so what are the
options to compile.
Thanks and Regards

I'm sure it's going to need some work.

Define "ready". GCC does not support the framework for the more advanced
(but necessary) optimizationtechniques like predication and speculative
loads. However, I have no doubts that this will change as soon as IA64 is
widely available ;)

As for "ready". GCC will definitely be ready to create (non-optimal) code
for the IA64. I don't know wether any special optimizations are currently
being developed for gcc, but I doubt it.

You mean "requires", not "enables" ;->

Well, although I _am_ a follower of the IA64 architecture, I am not sure
wether it will be that competitive, given the current schedule. There are
quite a few competing architectures.

Please note that all this is my personal opinion ;)

IA64

[Lynn Winebarger]

   I just saw a talk by Stephen Skedzielewski (manager of the IA64
compiler performance analysis team at Intel) giving an overview of
compilation techniques for the IA64 architecture.
   Is gcc ready/able for dealing with these kinds of issues?  (sounds like
the people at intel still aren't sure about how to look for the optimal
combination of all the different code optimizations their hardware
enables).

Just curious (because it sounds like a hard problem, and like the arch is
a vast improvement over the IA32 arch).
