[ia64] compilation error with utrace script

[ia64] compilation error with utrace script

[Masami Hiramatsu]

Hi,

Just an error report.

I got compile errors on 2.6.30-rc2/ia64 with recent systemtap(yesterday afternoon).

the command was:
stap --vp 0003 -ve 'probe process("duptest").syscall {printf("%d(0x%x, 0x%x, 0x%x)\n",\
 $syscall, $arg1, $arg2, $arg3)} probe kernel.function("syscall_trace_enter")\
 {printf("KP:%d(0x%x, 0x%x, 0x%x)\n", $regs->r15,$arg0,$arg1,$arg2)}' -c ./duptest

Without utrace probe, stap ran correctly.

I assume that utrace version on upstream kernel is older than expected one.

I'm unsure of what is going on here.  I just built Roland's latest
utrace kernel on x86_64 (2.6.30-rc3), and the utrace tests build and run
correctly.
