Error in Chapter 9 - ABI

[rahul-ar]

For example, on IA64 a function descriptor consists of two components; the address of the function (that being a 64 bit, or 8 byte value) and the address of the global pointer (gp). The ABI specifies that r1 should always contain the gp value for a function. This means that when you call a function, it is the callees job to save their gp value, set r1 to be the new value (from the function descriptor) and then call the function.

In the above paragraph, it should be written that it is the caller's job to save the gp value[source]. Continuing, I think the word call should be formatted instead of the current then.
