public Address getPCAddress() {
		return entryList[0].pcaddr;
	}
Get the first code Address, within the function, where this symbol's storage actually
holds the value of the symbol.  If there is more than one mapping for the symbol, this
returns the code Address for the first mapping.  A null value indicates that the storage
is valid over the whole function (at least). If the value is non-null, the symbol storage
may be used for other purposes at prior locations.
@return the first use code Address or null
