Itanium cross-compiler for x86/64

Question

I need to compile my code for Itanium, but it seems that all of the compilers (ecc, gcc, orc) require an Itanium machine to do so. Any suggestions?

Answer 1

You need to set gcc up as a cross compiler. This involves building binutils and gcc yourself.

The IA64wiki at http://www.gelato.unsw.edu.au/IA64wiki/CrossCompilation has a tutorial on how to set this up.

Answer 2

I can only tell how I did it, perhaps not the best way or best tools.

I developed a very small priority-based Itanium kernel and test tasks long time ago. I started to develop it again (demand paging, fork system call...). The last time I compiled it is a week ago.

What I found is that compiling a cross compiler is a very hard task nowadays for IA64. And to get gcc and binutils to work together is an other problem. I tried many times compile cross compiler and binutils - no success). It seems that Itanium support has been forgotten, at least very much worse than some years again.

However, I found packages for the cross compiler, binutils and ski simulator binary. All starts working immediately (well, ski does not show TLB info).

I have Ubuntu 12, Linux kernel 3.2 AMD64

How to find the tools:

• Ski:
  • Ubuntu Sotfware Center: Ski/IA-64 instruction set simulator (binary)
• Cross tools (work together!):
  • gcc-ia64-linux-gnu-4.7.1-0.1.20120606.fc18.1.x86_64.rpm
  • binutils-ia64-linux-gnu-2.22.52.0.3-3.fc18.x86_64.rpm

(Hmm... I compiled the Kernel, I think that application library support can be bad or non existent?)

Answer 3

There's Itanium version of Windows, so of course Visual studio can generate code for Itanium
