Member Function Documentation

addObject()

void StackLayout::addObject	(	const Value *	V,
		unsigned	Size,
		unsigned	Alignment,
		const StackColoring::LiveRange &	Range
	)

Add an object to the stack frame.

Value pointer is opaque and used as a handle to retrieve the object's offset in the frame later.
