assume that the called function will pop off the stack space used to
pass arguments, unless it takes a variable number of arguments.
+@item syscall_linkage
+@cindex @code{syscall_linkage} attribute
+This attribute is used to modify the IA64 calling convention by marking
+all input registers as live at all function exits. This makes it possible
+to restart a system call after an interrupt without having to save/restore
+the input registers. This also prevents kernel data from leaking into
+application code.

+@cindex @code{version_id} attribute
+This IA64 HP-UX attribute, attached to a global variable or function, renames a
symbol to contain a version string, thus allowing for function level
versioning. HP-UX system header files may use version level functioning
for some system calls.
