    Add arch_ptrace_stop · 1a669c2f
    Roland McGrath 提交于
    This adds support to allow asm/ptrace.h to define two new macros,
    arch_ptrace_stop_needed and arch_ptrace_stop.  These control special
    machine-specific actions to be done before a ptrace stop.  The new code
    compiles away to nothing when the new macros are not defined.  This is the
    case on all machines to begin with.
    
    On ia64, these macros will be defined to solve the long-standing issue of
    ptrace vs register backing store.
