This packet is not probed by default; the remote stub must request it,
by supplying an appropriate @samp{qSupported} response (@pxref{qSupported}).
+If the remote stub indicates it supports the augmented form of this

+contain a semicolon-separated list of @samp{@var{name}=@var{value}}
+arguments. The currently supported arguments are:

+@table @code

+A hexadecimal number specifying the address of the @samp{struct
+link_map} to start reading the library list from. If unset or zero
+then the first @samp{struct link_map} in the library list will be
+chosen as the starting point.

+@item prev=@var{address}
+A hexadecimal number specifying the address of the @samp{struct

+specified by the @samp{start} argument. If unset or zero then
