[Xen-ia64-devel] Strange code in ivt.S

[tgingold@xxxxxxx]

Hi,

A few lines after ENTRY(break_fault), there is strange code (at least to me):
        movl r18=THIS_CPU(current_psr_ic_addr)
        ;;
        ld8 r18=[r18]    
        ;;
        cmp.eq p7,p0=r0,r17                     // is this a psuedo-cover?
(p7)    br.spnt.many dispatch_privop_fault

(r17 is cr.iim).

This seems buggy code related to old privify feature.
I think this creates garbage warning on the console when break 0 is
encountered in user code.

Tristan.
