	These classes are all managed with intrusive reference counting, so we also track a reference count.

Additional Inherited Members
Public Member Functions inherited from Halide::Internal::ExprNode< Ramp >
void	accept (IRVisitor *v) const override
	We use the visitor pattern to traverse IR nodes throughout the compiler, so we have a virtual accept method which accepts visitors.

Detailed Description

A linear ramp vector node.

This is vector with 'lanes' elements, where element i is 'base' + i*'stride'. This is a convenient way to pass around vectors without busting them up into individual elements. E.g. a dense vector load from a buffer can use a ramp node with stride 1 as the index.
