Detailed Description

Describes a (register) storage location and the ways it might be split into lanes.

Member Function Documentation

bool LanedRegister::restoreXml	(	const Element *	el,
		const AddrSpaceManager *	manage
	)

Restore object from XML stream.

Read XML of the form <register name=".." vector_lane_sizes=".."/>

Parameters

el	is the particular register tag
manage	is used to map register names to storage info

Returns

true if the XML description provides lane sizes
