 /* It's sometimes useful to be able to debug programs that you can't
    really stop for more than a fraction of a second.  To this end, the
    user can specify a tracepoint (like a breakpoint, but you don't
    stop at it), and specify a bunch of expressions to record the
    values of when that tracepoint is reached.  As the program runs,
    GDB collects the values.  At any point (possibly while values are
    still being collected), the user can display the collected values.
 
    This is used with remote debugging; we don't really support it on

        has.  However, the bitmask is reg_mask_len bytes long, so the
        valid register numbers run from 0 to reg_mask_len * 8 - 1.
 
        Also note that this mask may contain registers that are needed
        for the original collection expression to work, but that are
        not referenced by any bytecode.  This could, for example, occur
        when collecting a local variable allocated to a register; the
        compiler sets the mask bit and skips generating a bytecode whose
        result is going to be discarded anyway.
