[Xen-ia64-devel] VTi: break handling

[Tristan Gingold <Tristan.Gingold@xxxxxxxx>]

Hi,

in vmx_ivt.S:

// 0x2c00 Entry 11 (size 64 bundles) Break instruction (33)
ENTRY(vmx_break_fault)
    VMX_DBG_FAULT(11)
        mov r31=pr
    mov r19=11
    mov r30=cr.iim
    movl r29=0x1100
    ;;
>>    cmp.eq p6,p7=r30,r0
>>    (p6) br.sptk vmx_fault_11
    ;;
    cmp.eq  p6,p7=r29,r30
    (p6) br.dptk.few vmx_hypercall_dispatch
    (p7) br.sptk.many vmx_dispatch_break_fault
    ;;
    VMX_FAULT(11);
END(vmx_break_fault)

Is the '>>' section debug code ? I fear a bug here.

Thank you for comments,
Tristan.
