Member Function Documentation

addObject()

void StackLayout::addObject	(	const Value *	V,
		unsigned	Size,
		Align	Alignment,
		const StackLifetime::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.

computeLayout()

void StackLayout::computeLayout

(

)

Run the layout computation for all previously added objects.

getObjectAlignment()

Align llvm::safestack::StackLayout::getObjectAlignment ( const Value *  V )
