Itanium (IA64) Assembly Language

Jackson Allen — Wed, 12 Apr 2006 17:38:38 GMT

Where can I find information on the IA64 Assembly Language, syntax, naming convention, the way it is used in HP-UX 11.X?

I have an application that has 2 routines that were written in AS for HPPA CPU. I need to port it to the Itanium CPU. One routine is a contditional spinlock, that is it locks memory, swaps a word in shared memory with a register, unlocks memory and returns a value to indicate it got the lock or not. The other just locks memory and clears the lock.

The idea of locking memory is it causes register moves to memory to complete and updates cache so other CPUs will be able to see the change.

Thanks:

You could take a look at Linux kernel sources, it has those locking primitives for multiple CPU architectures.

There is also this book which talks about Itanium for Programmers:
