If you've been working through the recipes so far, you're off to a great start toward working through the remaining recipes. Like IA32, we can make system calls on IA64 so that we can interact with the operating system and perform other tasks. I wish I could say that if you are a pro at making IA32 system calls, IA64 system calls would be a breeze.
So much has changed between the two that we'll have to carry over only a small part of our IA32 knowledge. We'll still have to set up registers and use system call numbers to perform these operations, but that's about it. The registers that we will use are different for IA64; we have more available to us, so we can have more arguments to our system calls if need be, and even the method for invoking the system call has changed. Fear not, though, because we will walk through these...
