Subject: systemc: Partially implement the sc_module_name class.
X-Git-Tag: v19.0.0.0~1995
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7014f6948797efc74440d93a08285ddc1bca5d19;p=gem5.git

systemc: Partially implement the sc_module_name class.

This class is mostly implemented as defined by the spec, except that
it doesn't maintain the module name stack (which doesn't yet exist).
